Reduce usage of PCB IP version flag in UDP code. Maybe we can figure out
a good way for dual-stack UDP when we manage to remove the flag (nearly)
entirely from the code.
Eliminate IP_PCB_IPVER_INPUT_MATCH macro
Eliminate IP_PCB_IPVER_EQ macro
Reduce PCB_ISIPV6 macro usage some more
Review with Simon: Remove dead code (since 2003)
Review with Simon: Init TCP/UDP/RAW PCBs with correct IP types in _new
functions to make my changes work correct
Together with Simon: Eliminate last instances of isipv6 member in pcbs;
Change signature of ip_output, ip_output_if, ip_output_if_src,
ip_output_hinted, ip_route, ip_netif_get_local_ip, ip_route_get_local_ip and
tcp_eff_send_mss not to take an isipv6 parameter. Use the IP version of the
destination address instead.

udp.c: Further udp_input simplifications
Implement UDP dual-stack PCB support
minor: Cleanups in raw/tcp/udp code by using macros and reducing #ifdefs
udp: udp_send and udp_send_chksum: Check for PCB NULL pointer and PCB
must not be the new IP_ANY_TYPE, but a real IPv4 and IPv6 address
No need for dual-stack code in ip4.c and icmp.c -> use ip4 only versions
Fix compile when PPPOE is enabled
Cleanup: Create new file ip.c and move dual-stack code from ipv4 and ipv6
folder in there
Add compatibility macro for udp_new_ip6()
Rework DHCP PCB handling: Old code registered one UDP PCB per netif where
DHCP was active and there was a special case in udp_input() for this. New
implementation uses one PCB for all netifs and removes special case in
udp_input().
Implement support for IP_ANY_TYPE in SNMP
Implement support for UDP IP_ANY_TYPE in netconn API
Implement dual-stack in SNMP for netconn API
Minor: Avoid ip_input() call indirection for when only IPv4 or IPv6 are

implementation -> revert
Apply patch from Derek Pravala: Fix segfault in ip6_route when there is
no default netif
Add compatibility macro for tcp_new_ip6()

Port netifapi to new simple tcpip API call method
Port PPP API to new simple tcpip API call method
Minor TCPIP API call functions cleanup
pppol2tp.c: Avoid an #ifdef - there is a new UDP API function that can be
used here
tcpip API calls: Implement LWIP_NETCONN_SEM_PER_THREAD support for ALL
API calls
LwipMibCompiler: MibTree: Adapt coding style to the rest of the C# project
LwipMibCompiler: Don't generate empty root nodes

Fix year in recent CHANGELOG entries
udp: use netif addr as src for multicast sockets
Mark Lakata (1):
PPP, IAR EWARM won't compile ppp-new due to keyword clash
Philip Gladstone (1):
Patch #8360 (Speed up the acquisition of SLAAC addresses) - adapted to
bug #43784
Philipp Toelke (1):
httpd: fix sending of data from send_headers
Robert Szewczyk (1):
pbuf_take: make it comply with API specifications
Simon Goldschmidt (192):
Fixed bug #33802 tcpip: tcpip_callbackmsg_new sets msg->type to wrong type
Fixed bug #33801 Corruption of nd6 tables
Fixed bug #33804 LWIP_IPV6_MLD #define missing from mld6.c
(bug #30185): added LWIP_FIONREAD_LINUXMODE that makes ioctl/FIONREAD
return the size of the next pending datagram.
fixed bug #33551 (ARP entries may time out although in use) by sending an
ARP request when an ARP entry is used in the last minute before it would time
out.
ETHARP_SUPPORT_STATIC_ENTRIES: don't need the member 'static_entry' on
struct etharp_entry, we can use 'state' to mark them as static
ETHARP_STATE_STABLE_REREQUESTING: no need for member 'netif' in 'struct
etharp_entry' if we re-request only from etharp_output() and use etharp_tmr()
to reset the state of such entries to ETHARP_STATE_STABLE: that way, we also
only send one ARP request per ARP_TMR_INTERVAL, but only if the entry is really
still used.
correctly prefix all functions with 'etharp_' (also static functions)
bug #33634 ip_forward() have a faulty behaviour: Added pbuf flags to mark
incoming packets as link-layer broadcast/multicast. Also added code to allow
ip_forward() to forward non-broadcast packets to the input netif (set
IP_FORWARD_ALLOW_TX_ON_RX_NETIF==1).
freeing ooseq pbufs when the pbuf pool is empty implemented for
NO_SYS==1: when not using sys_check_timeouts(), call PBUF_CHECK_FREE_OOSEQ() at
regular intervals from main level.
forgot CHANGELOG: freeing ooseq pbufs when the pbuf pool is empty
implemented for NO_SYS==1: when not using sys_check_timeouts(), call
PBUF_CHECK_FREE_OOSEQ() at regular intervals from main level.
init.c: changed some checks from runtime to compiletime (had to adapt
some defines in ip.h for that)
fixed bug #31084 (socket API returns always EMSGSIZE on non-blocking
sockets if data size > send buffers) -> now lwip_send() sends as much as
possible for non-blocking sockets and only returns EWOULDBLOCK if the buffers
are full
Removed commas from the end of enum lists
Fixed some C compiler warnings
Prevent non-static function that is not declared in header file
IPv4: splitted IPv4 header fields version/len and tos, made macros depend
on BYTE_ORDER to prevent unnecessary calls to htons()
ETHARP_SUPPORT_VLAN: add support for an external VLAN filter function
instead of only checking for one VLAN (define ETHARP_VLAN_CHECK_FN)
adapted unit tests to changes after adding IPv6 support
Fixed complier error for CHECKSUM_CHECK_TCP==0
fixed bug #33962 TF_FIN not always set after FIN is sent. (This merely

aggregated and sent to application
DHCP uses LWIP_RAND() for xid's (bug #30302)
Make LWIP_RAND optional (useful for small targets)
fixed bug #34072: UDP broadcast is received from wrong UDP pcb if udp
port matches
Fixed typo: TCP_SNDQUEUELOWAT must be less than TCP_SND_QUEUELEN (as
checked in init.c), not greater
lwip_accept: fixed warning about accessing uninitialized 'port' when
SOCKETS_DEBUG is enabled
Added a config option to randomize initial local TCP/UDP ports (so that
different port ranges are used after a reboot; bug #33818; this one added
tcp_init/udp_init functions again);
use pcb->mss instead of TCP_MSS for preallocate mss-sized pbufs (bug
#34019)
nd6: use a static buffer to process RA options instead of using
mem_malloc()
splitted ppp.h to an internal and external header file to get a clear
separation of which functions an application or port may use (task #11281)
Converted runtime-sanity-checks into compile-time checks that can be
disabled (since runtime checks can often not be seen on embedded targets)
fixed default value of TCP_SND_BUF to not violate the sanity checks in
init.c
Implemented timeout on send (TCP only, bug #33820)
Corrected fix for bug #34072 (UDP broadcast is received from wrong UDP
pcb if udp port matches): pcbs bound to IPADDR_ANY did not receive broadcasts
any more (bug #34294)
fixed bug #34355: nagle does not take snd_buf/snd_queuelen into account
Fixed tcp_accepted define (need brackets around the parameter)

including FIN can lose data
Merge branch 'master' of ssh://git.sv.gnu.org/srv/git/lwip

fixed unit tests (one TCP test failed, removed comma at the end of array
initializers)
added unit tests for data-after-FIN
fixed bug #28288: Data after FIN in oos queue
Implemented limiting data on ooseq queue (task #9989) (define
TCP_OOSEQ_MAX_BYTES / TCP_OOSEQ_MAX_PBUFS in lwipopts.h), added unit test for
this new feature
Tried to fix bug #32417 ("TCP_OVERSIZE seems to have problems with
(fast-)retransmission"): Reset pcb->unsent_oversize in 2 more places...

fixed bug #34426: tcp_zero_window_probe() transmits incorrect byte value
when pcb->unacked != NULL
Added unit test case for persist timer / zero window probes

protocols are enabled
fixed bug #34541: LWIP_U32_DIFF is unnecessarily complex: removed that

christiaans (120):
Match update_arp_entry() to prototype.

trees directly in the mib tree.
Added newlines in debug output, small optimalisations, more work on
'getnext', fixed 'get' on udp table.
First getnext succes, values are returned insead of NULLs, empty tables
are skipped. Limitation: a single varbind per request, so 'snmptable' will fail.
Corrected snmp_delete_arpidx_tree() to be called in the expired state,
not only maxage.
Fixed compilation for LWIP_SNMP 0.
Improved TRAP interfacing. Varbinds maybe allocated at (external) trap
source as wel. Added trap destination settings.

invalid genError return on varbindlist parse error, changed badValue into
noSuchName error for non-writeable objects.
Fixed up mib_external_node support, snmpwalk works for external objects.
Only mentioning SNMP development additions instead of changes, since
we're in pre-alpha.

Partially accepted patch #5449 for ANSI C compatibility / build fixes.
Fixed bug #17574 corrected UDP-Lite protocol identifier.
Fixed decoding of negative integers in snmp_asn1_dec_s32t(), removed
EXPERIMENTAL status.

Replaced tabs with space.
Trimmed whitespace at line ends.
Added missing NULL return checks for snmp_mib_lrn_alloc() and trimmed
whitespace at line ends.
Initial attempt at fixing bug #17922, calling for reviewers. This seems
to work for me, more or less, but it looks like it breaks TCP.

Added snmp_send_trap() parameter, caller must pass enterprise id for
enterprise secific traps.
Changed heap to use naturally aligned start address and added near-fit
case to #17922 fix.

Fixed false triggers of request_timeout.
Included xid to some DEBUGFs.
Added MEM_LIBC_MALLOC option as workaround for failing mem_malloc().

davidhaas (27):
----------------------------------------------------------------------
Added lightweight protection. In coldfire this is implemented by disabling
Add the following features and bugfixes:
Fixed some build issues regarding snmp.h
sys_thread_new() now returns the thread (request from Marc Boucher).
Fix some compile issues with both coldfire and unix builds.
Made sys_arch_prot() interface more generic by returning sys_prot_t
instead
By request: moved lightweight protection to macros.
Allow minimal unix target to build in cygwin (but not necessarily run).
Fixed SYS_ARCH_PROTECT macros when NO_SYS is not defined.
Fixed build for coldfire after last debug.h and opt.h changes.
Added default settings for DBG_MIN_LEVEL and definitions for the possible
Fix to last fix for bug 2826: find_arp_entry() was now not finding any
Fixed up and made work a PBUF_REF type. Most of the code uses this now
Fixed memory leak caused by my last pbuf_ref change.
Typo bug. The wrong semaphore was being signalled.
Fixed minor compile issues.
Made lwip timeout measurements accurate by no longer returning 1
millisecond
Fix pbuf_chain() to update tot_len of last buffer in first chain properly.
Fixed issue in pbuf_take(): old pbuf of type PBUF_REF was being
referenced
In keeping with pbuf->ref always having the count of the number of
pointers
Fixed last change to pbuf_take. There were two calls to pbuf_free in a
row.
Updated sys_arch documentation to make new timeouts clearer.
Fixed bug where tearing down a connection would cause loss of memory.
Made memory stats more accurate (real amount and max amount of memory
used).
Fix memory leaks.
Got rid of pbuf_pool_alloc_cache and pbuf_pool_free_cache. Also got rid of
fbernon (277):
no message
udp.c: remove obsolete line "static struct udp_pcb *pcb_cache = NULL;"
api_lib.c: Fix "[patch #5764] api_lib.c cleanup: after patch #5687" (from
Dmitry Potapov).
api_msg.c: Remove some compiler warnings : parameter "pcb" was never
referenced.
opt.h, sockets.h: add new configuration options
(LWIP_POSIX_SOCKETS_IO_NAMES, ETHARP_TRUST_IP_MAC, review SO_REUSE).
opt.h, ip_frag.h, tcpip.h, tcpip.c, ethernetif.c: add new configuration
option named ETHARP_TCPIP_ETHINPUT, which enable the new tcpip_ethinput. Allow
to do ARP processing for incoming packets inside tcpip_thread (protecting ARP
layer against concurrent access). You can also disable old code using tcp_input
with new define ETHARP_TCPIP_INPUT set to 0. Older ports have to use
tcpip_ethinput.
Implement SO_RCVTIMEO on UDP sockets/netconn.
Fix some "little" build problems, and a redundancy call to
"lwip_stats.link.recv++;" in low_level_input() & ethernetif_input().
Implement LWIP_SO_RCVTIMEO configuration option to enable/disable
SO_RCVTIMEO on UDP sockets/netconn.
Keepalive values can be configured at compile time, but don't change this
unless you know what you're doing (default are RFC1122 compliant).
Keepalive values can be configured at run time with LWIP_TCP_KEEPALIVE,
but don't change this unless you know what you're doing (default are RFC1122
compliant). Note that TCP_KEEPIDLE and TCP_KEEPINTVL have to be set in seconds.
Based on patch from Dmitry Potapov, bug#19225.
New configuration option LWIP_IGMP to enable IGMP processing. Based on
only one filter per all network interfaces. Declare a new function in netif to
enable to control the MAC filter (to reduce lwIP traffic processing).
Add igmp.h and igmp.c inside tree :
Remove unimplemented "memp_realloc" function from memp.h.
Add return types to tcpip_apimsg() and api_msg_post() to check ERR_MEM
problems (api_lib.c can be change now).
tcpip.c: Initialize tcpip's mbox, and verify if initialized in
tcpip_input, tcpip_ethinput, tcpip_callback, tcpip_apimsg, to fix a init
problem with network interfaces. Also fix a compiler warning.
memp.h, stats.c: Fix stats_display function where memp_names table wasn't
synchronized with memp.h
Remove obsolete include from my port.
api_msg.c, igmp.c, igmp.h: Fix C++ style comments
opt.h: Add LWIP_NETIF_CALLBACK (to avoid compiler warning) and set it to
0.
api_lib.c, api_msg.c, tcpip.c: integrate sys_mbox_fetch(conn->mbox, NULL)
calls from api_lib.c to tcpip.c's tcpip_apimsg(). Now, use a local variable and
not a dynamic one from memp to send tcpip_msg to tcpip_thread in a synchrone
call. Free tcpip_msg from tcpip_apimsg is not done in tcpip_thread. This give a
faster and more reliable communication between api_lib and tcpip.
ethernetif.c: update netif->input calls to check return value. In older
ports, it's a good idea to upgrade them, even if before, there could be another
problem (access to an uninitialized mailbox).
api_lib.c: somes resources couldn't be freed if there was errors during
netconn_new_with_proto_and_callback.
api_msg.h, api_msg.c: Remove obsolete API_MSG_ACCEPT and do_accept (never
used).
stats.h, stats.c, msg_in.c: Stats counters can be change to u32_t if
necessary with the new option LWIP_STATS_LARGE. If you need this option, define
LWIP_STATS_LARGE to 1 in your lwipopts.h. More, unused counters are not defined
in the stats structs, and not display by stats_display(). Note that some
options (SYS_STATS and RAW_STATS) are defined but never used. Fix msg_in.c with
the correct #if test for a stat display.
api_lib.c (from Dmitry Potapov) : patch for netconn_write(), fixes a
possible race condition which cause to send some garbage. It is not a
definitive solution, but the patch does solve the problem for most cases.
opt.h, tcpip.c: New configuration option LWIP_ARP allow to disable ARP
init at build time if you only use PPP or SLIP. The default is enable. Note we
don't have to call etharp_init in your port's initilization sequence if you
use tcpip.c, because this call is done in tcpip_init function.
netif.h, netif.c: A new NETIF_FLAG_ETHARP flag is defined in netif.h, to
allow to initialize a network interface's flag with. It tell this interface is
an ethernet device, and we can use ARP with it to do a "gratuitous ARP" (RFC
3220 "IP Mobility Support for IPv4" section 4.6) when interface is "up" with
netif_set_up().
opt.h, netif.h, dhcp.h, dhcp.c: New configuration option
LWIP_NETIF_HOSTNAME allow to define a hostname in netif struct (this is just a
pointer, so, you can use a hardcoded string, point on one of your's ethernetif
field, or alloc a string you will free yourself). It will be used by DHCP to
register a client hostname, but can also be use when you call snmp_set_sysname.
Minor. Add LWIP_NETIF_HOSTNAME in skeleton and comment on #endif for
LWIP_SNMP.
api.h, api_lib.c, sockets.c: netbuf_ref doesn't check its internal
pbuf_alloc call result and can cause a crash. lwip_send now check netbuf_ref
result.
Missing recv_timeout initialize in accept_function. Minor style fix
(indent, mbox checking...)
most of files: prefix all debug.h define with "LWIP_" to avoid any
conflict with others environment defines (these were too "generic").
Fix on NETIF_FLAG_ETHARP test (test inverted)
api_msg.c: add a "pcb_new" helper function to avoid redundant code, and
to add missing pcb allocations checking (in do_bind, and for each raw_new).
Fix style.
Add NETIF_FLAG_ETHARP flag and comments in this skeleton.
ip.c: if IP_REASSEMBLY is set to 1, don't set the IP_DF ("Don't
fragment") flag in the IP header in IP output packets.
Don't set the IP_DF ("Don't fragment") flag in the IP header in IP output
packets. See patch #5834.
sockets.c: remplace ENOBUFS errors on alloc_socket by ENFILE to be more
BSD compliant.
api_msg.c: Fix bug #16830: "err_tcp() posts to connection mailbox when no
pend on the mailbox is active". Now, the post is only done during a connect,
and do_send, do_write and do_join_leave_group don't do anything if a previous
error was signaled.
Fix mistakes in netconn's error field checking.
opt.h, tcpip.h, tcpip.c, netifapi.h, netifapi.c: New configuration option
LWIP_NETIF_API allow to use thread-safe functions to add/remove netif in list,
and to start/stop dhcp clients, using new functions from netifapi.h. Disable as
default (no port change to do).
opt.h: rename DBG_TYPES_ON & DBG_MIN_LEVEL with LWIP_ prefix.
Remove forgotten printf in pbuf_init().
Minor fix (tab, indent...) to respect source code style...
sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fix bug #19162
"lwip_sento: a possible to corrupt remote addr/port connection state". Reduce
problems "not enought memory" with netbuf (if we receive lot of datagrams).
Improve lwip_sendto (only one exchange between sockets api and api_msg which
run in tcpip_thread context). Add netconn_sento function. WARNING, if you
directly access to "fromaddr" & "fromport" field from netbuf struct, these
fields are now renamed "addr" & "port".
sockets.c, api_lib.c, api_msg.h, api_msg.c, netifapi.h, netifapi.c,
tcpip.c: Include a function pointer instead of a table index in the message to
reduce footprint. Disable some part of lwip_send and lwip_sendto if some
options are not set (LWIP_TCP, LWIP_UDP, LWIP_RAW).
Include inet.h to avoid warnings (see
http://savannah.nongnu.org/patch/?5865).
Minor fix (tabs)
tcpip.c, igmp.h, igmp.c: Fixed bug "#19800 : IGMP: igmp_tick() will not
work with NO_SYS=1". Note that igmp_init is always in tcpip_thread (and not in
tcpip_init) because we have to be sure that network interfaces are already
added (mac filter is updated only in igmp_init for the moment).
Remove warning in snmp/msg_in.c
Minor fixs to reduce footprint on the "recv part" of Sequential API...
Minor Fix (unsed code, spaces, idents..)
api_msg.c: Fix some errors forwarding
(https://savannah.nongnu.org/task/?6880)
Remove warning (missing include)
Minors fix (spaces, comments, unused variable)
api.h, api_lib.c, api_msg.h, api_msg.c: change the struct api_msg_msg to
see which parameters are used by which do_xxx function, and to avoid "misusing"
parameters (patch #5938).
sys.h, sys.c, api_lib.c, tcpip.c: remove sys_mbox_fetch_timeout() (was
only used for LWIP_SO_RCVTIMEO option) and use sys_arch_mbox_fetch() instead of
sys_mbox_fetch() in api files. Now, users SHOULD NOT use internal lwIP features
like "sys_timeout" in their application threads.
Minor fix (spaces, indent) and check for LWIP_SO_RCVTIMEO..
api.h, api_lib.c, api_msg.c, sockets.c: group the different
NETCONN_UDPxxx code in only one part...
api_lib.c: Fixed bug #5957 "Safe-thread problem inside netconn_recv" to
return an error code if it's impossible to fetch a pbuf on a TCP connection
(and not directly close the recvmbox).
api_lib.c, sockets.c: Fixed bug #5958 for netconn_listen (acceptmbox only
allocated by do_listen if success) and netconn_accept errors handling. In most
of api_lib functions, we replace some errors checkings like "if (conn==NULL)"
by ASSERT, except for netconn_delete.
api_lib.c: Implement SO_RCVTIMEO for accept and recv on TCP connections,
such present in patch #5959.
Fixed patch #5965 : Remove unused conntype in struct api_msg_msg, by
Simon Goldsmith
Minor, fix files modified by last patch...
Minor fix for warning: pbuf_copy declaration is now mandatory (since it's
used in icmp.c)
Minor, fix an obsolete comment about LWIP_SO_RCVTIMEO
Fix typo and remove RAW_STATS (not used)
Minor fix (spaces)
Add LWIP_TCPIP_CORE_LOCKING option (0 as default value) to experiment
"locking" as feature to communicate with tcpip_thread for sequential API
(netconn & socket layers). Add a alternative code for lwip_sendto to how the
code can be optimized with such feature....
Just add a comment to explain that the lwip_sendto patch for
LWIP_TCPIP_CORE_LOCKING option is just show a sample (it's not a full
implementation, RAW connection and "to" field are not handled, ...)
Patch from Jared Momose (address@hidden) for bug #19699 : "Bug in SNMP
ASN1 decode; submitted patch"
Contrib module by Dominik Spies: autoip.h, autoip.c, dhcp.h, dhcp.c,
netif.h, netif.c, etharp.h, etharp.c, opt.h: AutoIP implementation available
for IPv4, with new options LWIP_AUTOIP and LWIP_DHCP_AUTOIP_COOP if you want to
cooperate with DHCP. Some tips to adapt (see TODO mark in the source code).
Minor fix (coding style)
Minor fix. Add comments in source file from documentation text file by
Dominik Spies.
Minor fix. Add "static" to IGMP's global variables, and rename group_list
to igmp_group_list...
tcp_out.c: Fix for bug #20075 : "A problem with keep-alive timer and TCP
flags" where TCP flags wasn't initialized in tcp_keepalive. Reported by
Srinivas Gollakota with help of Oleg Tyshev.
Partial fix for bug# 20147: "getsockopt() with SO_ERROR option" 'socket
layer error is not updated if no operation on netconn).
Minor fix (comment is not at the good place)
opt.h, mem.h, mem.c, memp.c, pbuf.c, ip_frag.c, vj.c: Fix bug #20162.
Rename MEM_ALIGN in LWIP_MEM_ALIGN and MEM_ALIGN_SIZE in LWIP_MEM_ALIGN_SIZE to
avoid some macro names collision with some OS macros.
debug.h, api_msg.c: change LWIP_ERROR to use it to check errors like
invalid pointers or parameters, and let the possibility to redefined it in
cc.h. Use this macro to check "conn" parameter in api_msg.c functions (some
others change will be done...).
api_lib.c: change return expression in netconn_addr and netconn_peer,
because conn->err was reset to ERR_OK without any reasons (and error was
lost)...
tcp_in.c: Fix bug #20126 : Zero ssthresh bug (by Per-Henrik Lundblom and
Kieran Mansley).
Minor fix: warning, type... for patch #5952 : Integration of AutoIP module
Some changes for AutoIP integration in tcpip.c, and some comments.
Minor changes: fix some comments for Doygen documentation
autoip.h/.c: change autoip_init & autoip_create_rand_addr to use netif's
MAC address and tried_llipaddr to generate an "autoip"...
sockets.c: process NETCONN_RAW connections with LWIP_TCPIP_CORE_LOCKING=1
netifapi.h, netifapi.c, tcpip.h, tcpip.c: Update code to handle the
option LWIP_TCPIP_CORE_LOCKING, and do some changes to be coherent with last
modifications in api_lib/api_msg (use pointers and not type with table, etc...)
autoip.c: replace most of rand() calls by a macro LWIP_AUTOIP_RAND which
compute a "pseudo-random" value based on netif's MAC and some autoip fields.
It's always possible to define this macro in your own lwipopts.h to always use
C library's rand(). Note that autoip_create_rand_addr doesn't use this macro.
Minor fix (extra spaces)
sockets.h, sockets.c: Implement MSG_PEEK flag for recv/recvfrom functions.
ip.h, etharp.c: Fix warnings & errors about LWIP_NETIF_HWADDRHINT
(perhaps compiler dependant)
Minor fix (indent)
sockets.c: Fix a possible problem because any new socket can't be created
during the "close" (which can be "long" since fix for bug #20021).
Fix minor patch #5741 build error...
Fix bug #20315: possible memory leak problem if tcp_listen failed,
because current code doesn't follow rawapi.txt documentation.
api_msg.c: Fix bug #20318: api_msg "recv" callbacks don't call pbuf_free
in all error cases.
opt.h, netif.h, netif.c, ethernetif.c: Add new configuration option to
add a link callback in the netif struct, and functions to handle it. Be
carefull for port maintainers to add the NETIF_FLAG_LINK_UP flag (like in
ethernetif.c) if you want to be sure to be compatible with future changes...
Minor fix: debug text inside ethernetif_input
Fix do_delconn when used with LWIP_TCPIP_CORE_LOCKING=1 on "non-TCP"
connections...
Minor Fix: remove obsolete MEMP_NUM_API_MSG define and update comment
igmp.c: Fix bug #20595 to accept IGMPv3 "Query" messages.
Minor fix (warning, linker helper) signaled by Bill Florac
Minor fix on pbuf_init (fix warning) and use same coding style that
mem.h, sys.h, tcp.h, etc...
Minor fix (warning when LWIP_DEBUG is undefined)
Minor fix (warning when LWIP_DEBUG is undefined)
Minor fix (warnings on unused args, wrong type, cast u32_t to u16_t...)
Minor fix (spaces)
igmp.h, igmp.c, ip.c: Fix minor changes from bug #20503 : IGMP
Improvement. This is mainly on using lookup/lookfor, and some coding styles...
udp.c: Fix for bug #20503 : IGMP Improvement. Enable to receive a
multicast packet on a udp pcb binded on an netif's IP address, and not on "any".
stats.h, stats.c, igmp.h, igmp.c, opt.h: Fix for bug #20503 : IGMP
Improvement. Introduce IGMP_STATS to centralize statistics management.
Minor Fix (remove unused USE_ROUTER_ALERT and some coding style)
Comments Fix for Doxygen documentation
Minor change: add in tcp_in.c in tcp_input(), some calls to handle error
statistics (stats & snmp)
Minor changes (tabs, ident, coding style...)
Add raw_init in tcpip_init + minor changes (tabs, ident, coding style...)
Minor changes (tabs)
Fix comment
Minor change (fix comment)
Fix wrong define for both pool "struct tcpip_msg" + minor fix (coding
style)
Replace PBUF_LINK_HLEN before PBUF_POOL_BUFSIZE, restore PPP options
changed by Marc Boucher but lost with last Jared changes...
Force a build error if MEMP_NUM_TCPIP_MSG is always defined
Rename pbuf's "flgs" in "flags" (see in [lwip-devel] Last changes by Marc)
Forget to rename this line (pbuf->flgs->pbuf->flags)
tcpip.h, tcpip.c, ethernetif.c, opt.h: remove options ETHARP_TCPIP_INPUT
& ETHARP_TCPIP_ETHINPUT, now, only "ethinput" code is supported, even if the
name is tcpip_input (we keep the name of 1.2.0 function).
Minor fix (spaces and comment)
netif.h, netif.c, opt.h: Rename LWIP_NETIF_CALLBACK in
LWIP_NETIF_STATUS_CALLBACK to be coherent with new LWIP_NETIF_LINK_CALLBACK
option before next release.
netif.h, netif.c: Integrate "patch #6163 : Function to check if link
layer is up". Add a netif_is_link_up() function if LWIP_NETIF_LINK_CALLBACK
option is set.
First fix for "bug #20900 : Potential crash error problem with
netconn_peer & netconn_addr". Introduce NETCONN_LISTEN netconn_state and remove
obsolete ones (NETCONN_RECV & NETCONN_ACCEPT).
Fix coding style (use #if and not #ifdef) for IPv6
tcpip.c: Fix TCPIP_MSG_INPKT processing: now, tcpip_input can be used for
any kind of packets. These packets are considered like Ethernet packets
(payload pointing to ethhdr) if the netif got the NETIF_FLAG_ETHARP flag.
Else, packets are considered like IP packets (payload pointing to iphdr).
Add init.h, init.c, Change opt.h, tcpip.c: Task #7213 "Add a lwip_init
function" Add lwip_init function to regroup all modules initializations, and to
provide a place to add code for task #7142 "Sanity check user-configurable
values". Ports maintainers should remove direct initializations calls from
their code, and add init.c in their makefiles. Note that lwip_init() function
is called inside tcpip_init, but can also be used by raw api users since all
calls are disabled when matching options are disabled. Also note that their is
new options in opt.h, you should configure in your lwipopts.h (they are enabled
per default).
Minor fix: replace C++ comments by C comments.
Minor Fix (ident)
igmp.h, igmp.c, tcpip.c, init.c, netif.c: change igmp_init and add
igmp_start. igmp_start is call inside netif_add. Now, igmp initialization is in
the same spirit than the others modules. Modify some IGMP debug traces.
Minor fix (coding style, comments, spaces, endline...)
init.c: Add first version of lwip_sanity_check for task #7142 "Sanity
check user-configurable values".
igmp.h, igmp.c: Some changes to remove some redundant code, add some
traces, and fix some coding style.
Replace API programmation error checking for IGMP join/leave
(ismulticast(addr)) by LWIP_ERROR checking.
Minor change (ident, remove comment, change trace text)
Add some others sanity checkings
Add netbuf.h, netbuf.c, Change api.h, api_lib.c: #7249 "Split netbuf
functions from api/api_lib". Now netbuf API is independant of netconn, and can
be used with other API (application based on raw API, or future "socket2" API).
Ports maintainers just have to add src/api/netbuf.c in their makefile/projects.
Minor fix (use ETHARP_HWADDR_LEN)
Minor fix (else, cause build error). Since SO_REUSE is always used in the
code (even if the current code is not working), it is defined in opt.h with 0
as default value (it's normal). So, the error is not if it is defined, but if
it is defined to 1.
Add enum snmp_ifType in snmp.h, and use it in network interfaces for
NETIF_INIT_SNMP
Add in igmp_joingroup & igmp_leavegroup a LWIP_ERROR checking on netif
value.
Replace "netif_default = NULL;" by "netif_set_default(NULL);" in
netif_remove (do some processing, like for SNMP...)
Changes for "#20503 IGMP Improvement". Initialize igmp_mac_filter to NULL
in netif_add (this field should be set in the netif's "init" function). Use the
"imr_interface" field (for socket layer) and/or the "interface" field (for
netconn layer), for join/leave operations. The igmp_join/leavegroup first
parameter change from a netif to an ipaddr. This field could be a netif's
ipaddr, or "any" (same meaning than ip_addr_isany).
Minor changes (fix some warnings like "function declaration isn't a
prototype" and "no previous prototype for 'lwip_init'"...)
Fix warnings inside sockets.c with "gcc" compilers. See "Description" in
http://www.opengroup.org/onlinepubs/007908799/xns/syssocket.h.html :
Replace mem_malloc call by memp_malloc, and use a new MEMP_NUM_IGMP_GROUP
option (see opt.h to define the value). It will avoid potential fragmentation
problems, use a counter to know how many times a group is used on an netif, and
free it when all applications leave it. MEMP_NUM_IGMP_GROUP got 8 as default
value (and init.c got a sanity check if LWIP_IGMP!=0).
Minor fix (add some parenthesis where macro expansion could cause
problems)
Move some build time checkings inside init.c for task #7142 "Sanity check
user-configurable values".
Change parameters list for sys_thread_new (see "task #7252 : Create
sys_thread_new_ex()"). Two new parameters have to be provided: a task name, and
a task stack size. For this one, since it's platform dependant, you could
define the best one for you in your lwipopts.h. For port maintainers, you can
just add these new parameters in your sys_arch.c file, and but it's not
mandatory, use them in your OS specific functions.
Integrate "task #7272 : LWIP_ICMP option". The new option LWIP_ICMP
enable/disable ICMP module inside the IP stack (enable per default). Be
careful, disabling ICMP make your product non-compliant to RFC1122, but help to
reduce footprint, and to reduce "visibility" on the Internet.
several-files: replace some #include "arch/cc.h" by "lwip/arch.h", or
simply remove it as long as "lwip/opt.h" is included before (this one include
"lwip/debug.h" which already include "lwip/arch.h"). Like that, default defines
are provided by "lwip/arch.h" if they are not defined in cc.h, in the same
spirit than "lwip/opt.h" for lwipopts.h.
DON'T WORRY, it's just a test on CVS keywords (I will remove)
DON'T WORRY, it's just a test on CVS keywords (I will remove)
DON'T WORRY, it's just a test on CVS keywords (I will remove)
Last sanity checking centralization for "task #7142 : Sanity check
user-configurable values".
Minor changes (but in lot of files): add #if/#endif for options where
they could miss. #if LWIP_xxx if always put after #include "lwip/opt.h" (note
this one indirectly include cc.h). Move others includes inside #if/#endif block.
Add some deprecated options from "task #7142 : Sanity check
user-configurable values".
sockets.c, ip.h, api.h, tcp.h: declare a "struct ip_pcb" which only
contains IP_PCB. Add in the netconn's "pcb" union a "struct ip_pcb *ip;" (no
size change). Use this new field to access to common pcb fields (ttl, tos,
so_options, etc...). Enable to access to these fields with LWIP_TCP=0.
igmp.h, igmp.c, netif.h, netif.c, ip.c: To enable to have interfaces with
IGMP, and others without it, there is a new NETIF_FLAG_IGMP flag to set in
netif->flags if you want IGMP on an interface. igmp_stop() is now called inside
netif_remove(). igmp_report_groups() is now called inside netif_set_link_up()
(need to have LWIP_NETIF_LINK_CALLBACK=1) to resend reports once the link is up
(avoid to wait the next query message to receive the matching multicast
streams).
Add missing include files.
Remove CVS keyword
enable to remove SNMP timer (which consumne several cycles even when it's
not necessary). snmp_agent.txt tell to call snmp_inc_sysuptime() each 10ms
(but, it's intrusive if you use sys_timeout feature). Now, you can decide to
call snmp_add_sysuptime(100) each 1000ms (which is bigger "step", but call to a
lower frequency). Or, you can decide to not call snmp_inc_sysuptime() or
snmp_add_sysuptime(), and to define the SNMP_GET_SYSUPTIME(sysuptime) macro.
This one is undefined by default in mib2.c. SNMP_GET_SYSUPTIME is called inside
snmp_get_sysuptime(u32_t *value), and enable to change "sysuptime" value only
when it's queried (any direct call to "sysuptime" is changed by a call to
snmp_get_sysuptime).
Add missing #if/#endif to fix build problems
Add missing #if/#endif to fix build problems with:
Add a sanity check for PPP, and a #if !NO_SYS/#endif for slipif_loop
Avoid to lost previous error codes in sockets.c and api_lib.c.
Fix "bug #21075 : pbuf_realloc() use with PBUF_RAM and MEM_LIBC_MALLOC
fails" signaled by Bill Florac
udp.h, udp.c, sockets.c: Changes for "#20503 IGMP Improvement". Add
IP_MULTICAST_IF option in socket API, and a new field "multicast_ip" in "struct
udp_pcb" (for netconn and raw API users), only if LWIP_IGMP=1. Add getsockopt
processing for IP_MULTICAST_TTL and IP_MULTICAST_IF.
Minor changes by Andrew Dennison: add sanity check, improve debug
messages for memp, fix some warnings...
Minor change, sys_prot_t is undefined is NO_SYS=1
Minor changes for debug (indent, and set LWIP_DBG_TYPES_ON to LWIP_DBG_ON
to have all traces selected display per default, in the same spirit that
LWIP_DBG_MIN_LEVEL is set per default to LWIP_DBG_LEVEL_OFF)
netifapi.h, netifapi.c: add functions netifapi_netif_set_up,
netifapi_netif_set_down, netifapi_autoip_start and netifapi_autoip_stop. Use a
common function to reduce a little bit the footprint (for all functions using
only the "netif" parameter).
netifapi.h, netifapi.c: add function netifapi_netif_set_default. Change
the common function to reduce a little bit the footprint (for all functions
using only the "netif" parameter).
sockets.c, api.h, api_lib.c: First step to fix "bug #20900 : Potential
crash error problem with netconn_peer & netconn_addr". VERY IMPORTANT: this
change cause an API breakage for netconn_peer, since a parameter type change.
Any compiler should cause an error without any changes in yours netconn_peer
calls (so, it can't be a "silent change"). It also reduce a little bit the
footprint for socket layer (lwip_getpeername & lwip_getsockname use now a
common lwip_getaddrname function since netconn_peer & netconn_addr have the
same parameters).
Fix CHANGELOG entry
Minor change (coding style)
Minor change (add a default value to tune for MEMP_NUM_REASSDATA in opt.h)
Add sanity checking on TCP_MAXRTX and TCP_SYNMAXRTX
Update documentation for the SNMP uptime timestamp.
Update documentation for the SNMP uptime timestamp.
Minor fix (remove warning)
Minor change (sanity check for MEMP_NUM_REASSDATA only done if
IP_REASSEMBLY=1)
Minor change (define DHCP_COARSE_TIMER_MSECS - using
DHCP_COARSE_TIMER_SECS - to use milliseconds like all others timers)
Minor change (coding style, #if/#endif to include icmp.h is not necessary)
api.h, api_lib.c, api_msg.c: Add macro API_EVENT in the same spirit than
TCP_EVENT_xxx macros to get a code more readable. It could also help to remove
some code (like we have talk in "patch #5919 : Create compile switch to remove
select code"), but it could be done later.
sockets.h, sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c, tcp.h,
tcp_out.c: Integrate "patch #6250 : MSG_MORE flag for send". MSG_MORE is used
at socket api layer, NETCONN_MORE at netconn api layer, and TCP_WRITE_FLAG_MORE
at raw api layer. This option enable to delayed TCP PUSH flag on multiple
"write" calls. Note that previous "copy" parameter for "write" APIs is now
called "apiflags".
Minor change, add comment for "apiflags" parameters.
api.h, api_lib.c, api_msg.c, sockets.c, opt.h: add SO_RCVBUF option for
UDP & RAW netconn. You need to set LWIP_SO_RCVBUF=1 in your lwipopts.h (it's
disabled by default). Netconn API users can use the netconn_recv_bufsize macro
to access it. This is a first release which have to be improve for TCP. Note it
used the netconn::recv_avail which need to be more "thread-safe" (note there is
already the problem for FIONREAD with lwip_ioctl/ioctlsocket).
sockets.c, api.h, api_lib.c, api_msg.h, api_msg.c: Fixed bug #20900. Now,
most of the netconn_peer and netconn_addr processing is done inside
tcpip_thread context in do_getaddr.
opt.h, init.c, tcpip.c, dhcp.c, dns.h, dns.c: add DNS client for simple
name requests with RAW api interface. Initialization is done in lwip_init()
with build time options. DNS timer is added in tcpip_thread context. DHCP can
set DNS server ip addresses when options are received. You need to set
LWIP_DNS=1 in your lwipopts.h file (LWIP_DNS=0 in opt.h). DNS_DEBUG can be set
to get some traces with LWIP_DEBUGF. Sanity check have been added. There is a
"todo" list with points to improve.
Minor changes on DNS client.
Minor changes on DNS client. Note that "compressed answers are fixed".
Minor changes on DNS client. Coding style & add "response" checking
Changes on DNS client. Add multiples dns servers support.
fix DNS problem with pbuf chain.
Minor changes on DNS.
Fix DNS client TTL processing.
api_msg.c, dns.h, dns.c: Implement DNS_DOES_NAME_CHECK option (check if
name received match the name query), implement DNS_USES_STATIC_BUF (the place
where copy dns payload to parse the response), return an error if there is no
place for a new query, and fix some minor problems.
Minor changes in DNS client.
Minor changes (typo and wrong defines names in sanity checks)
Minor change (doxygen tags)
Minor changes (documentation).
Minor change (redundant code)
Minor change: add #if 0 / #endif in ethernetif.c skeleton to avoid false
bug reports.
Minor change (forgot last CRLF)
Fix to be able to build SNMP with LWIP_ARP=0. It's not a perfect
solution, but I put some @todo points to review them later.
Fix macro ERR_IS_FATAL (else, no error is fatal).
First fix for bug #21664 "PPP code is broken".
Minor changes: dnsserver initialization with DNS_SERVER_ADDRESS in
dns_init
Minor changes: fix some problems with PPPoE include path, add small
comments in slip.c (unusual octal values?)
process "localhost" name in dns_gethostbyname
Changes for coding style (typo, use LINK_STATS_INC, tabs, ident, etc...).
Be careful, even if this change is minor, there is lot of lines modified, so,
an error is always possible (I hope there is no problems).
Minor changes: coding style (tabs, ident, etc...).
Minor changes: coding style (tabs, ident, etc...).
Minor changes: coding style (tabs, ident, etc...).
Include a temporary sample of queue.h to fix build.
Minor changes: coding style (tabs, ident, etc...).
Minor changes: coding style (tabs, ident, etc...).
Minor changes (tabs)
netdb.c: add a LWIP_DNS_API_HOSTENT_STORAGE option to decide to use a
static set of variables (=0) or a local one (=1). In this last case, your port
should provide a function "struct hostent* sys_thread_hostent( struct hostent*
h)" which have to do a copy of "h" and return a pointer ont the "per-thread"
copy.
Fix err_stderr[] table with new err.h defines.
dns.h, dns.c, opt.h: move DNS options to the "right" place. Most visibles
are the ones which have ram usage.
Minor change: move DNS_MSG_SIZE in opt.h, add comments.
api_msg.c, err.h, err.c, sockets.c, dns.c, dns.h: replace "enum
dns_result" by err_t type. Add a new err_t code "ERR_INPROGRESS".
Minor changes in PPP (coding style, tabs, idents...)
ip.c: Fix bug #21846 "LwIP doesn't appear to perform any IP Source
Address Filtering" reported by Tom Evans.
autoip.c, etharp.c: ip_addr.h: Integrate patch #6348: "Broadcast ARP
packets in autoip". The change in etharp_raw could be removed, since all calls
to etharp_raw use ethbroadcast for the "ethdst_addr" parameter. But it could be
wrong in the future.
Minor changes: fix some PPP traces.
rawapi.txt, api.h, api_lib.c, api_msg.h, api_msg.c, sockets.c, tcp.h,
tcp.c, tcp_in.c, init.c, opt.h: rename backlog options with TCP_ prefix,
limit the "backlog" parameter in an u8_t, 0 is interpreted as "smallest queue",
add documentation in the rawapi.txt file.
Minor changes in lwip folder: fix some warnings, coding style, and rename
"internal" netconn_alloc function.
Minor changes in lwip folder: fix some warnings.
Minor changes in lwip folder: fix some warnings.
sys_arch.txt, api.h, api_lib.c, api_msg.h, api_msg.c, tcpip.c, sys.h,
opt.h: Introduce changes for task #7490 "Add return value to sys_mbox_post"
with some modifications in the sys_mbox api: sys_mbox_new take a "size"
parameters which indicate the number of pointers query by the mailbox. There is
three defines in opt.h to indicate sizes for tcpip::mbox, netconn::recvmbox,
and for the netconn::acceptmbox. Port maintainers, you can decide to just add
this new parameter in your implementation, but to ignore it to keep the
previous behavior. The new sys_mbox_trypost function return a value to know if
the mailbox is full or if the message is posted. Take a look to sys_arch.txt
for more details. This new function is used in tcpip_input (so, can be called
in an interrupt context since the function is not blocking), and in recv_udp
and recv_raw.
Fix DHCP build problem.
tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the
field netconn::mbox (sys_mbox_t) per netconn::sem (sys_sem_t) for the task
#7490 "Add return value to sys_mbox_post".
tcpip.h, tcpip.c: add tcpip_callback_with_block function for the task
#7490 "Add return value to sys_mbox_post". tcpip_callback is always defined as
"blocking" ("block" parameter = 1).
api_msg.c, opt.h: replace DEFAULT_RECVMBOX_SIZE per
DEFAULT_TCP_RECVMBOX_SIZE, DEFAULT_UDP_RECVMBOX_SIZE and
DEFAULT_RAW_RECVMBOX_SIZE (to optimize queues sizes), like suggested for the
task #7490 "Add return value to sys_mbox_post".
tcpip.h, tcpip.c, api.h, api_lib.c, api_msg.c, sockets.c: replace the
field netconn::sem per netconn::op_completed like suggested for the task #7490
"Add return value to sys_mbox_post".
Minor change: add comment
ip.c: Integrate patch #6369" ip_input : checking before realloc".
rawapi.txt, api_msg.c, tcp.c, tcp_in.c, tcp.h: changes for task #7675
"Enable to refuse data on a TCP_EVENT_RECV call". Important, behavior changes
for the tcp_recv callback (see rawapi.txt).
Minor changes: fix some traces in ip_frag.c (coding style and end of
lines)
Minor changes: fix warning in dhcp_unfold_reply when LWIP_DEBUG=0
Minor changes: typo in doc files.
Minor changes: fix a warning: "src\core\ipv4\ip_frag.c (782) : warning:
potential uninitialized reference to "newpbuflen" in func "_ip_frag""
tcp.c, tcp_in.c, tcp.h, opt.h: Rename LWIP_CALCULATE_EFF_SEND_MSS in
TCP_CALCULATE_EFF_SEND_MSS to have coherent TCP options names.
dns.c: Fix bug #22108 "DNS problem" caused by unaligned structures.
Minor changes: replace directy call to memcpy by MEMCPY macro.
Minor changes: fix trace text in etharp.c
Minor change: add a trace in etharp.c, find_entry
dhcp.c: minor change for coding style
inet_chksum.c: minor change for coding style
api_msg.c: Fix bug #22530 "api_msg.c's recv_raw() does not consume data".
api_msg.c: fix the netbuf::addr field to point on the ip_src on the
pbuf's copy (about bug#22530).
api_msg.c: minor change, fix warning.
sockets.c: Fix bug #22435 "lwip_recvfrom with TCP break;". Using
(lwip_)recvfrom with valid "from" and "fromlen" parameters, on a TCP connection
caused a crash. Note that using (lwip_)recvfrom like this is a bit slow and
that using (lwip)getpeername is the good lwip way to do it (so, using recv is
faster on tcp sockets).
ppp: minor changes: fix some 'is unused' warning when debug is off.
igmp.h, igmp.c: Fix bug #22613 "IGMP iphdr problem" (could have some
problems to fill the IP header on some targets, use now the ip.h macros to do
it).
api_msg.c: fix wrong mailbox invalidate (NULL was used instead of
SYS_MBOX_NULL). Spoted by Silas Boyd-Wickizer.
sockets.h: minor changes, add comments for ToS options
stats.h: Fix some build bugs introduced with patch #6483 (missing some
parameters in macros, mainly if MEM_STATS=0 and MEMP_STATS=0).
sockets.c: fixed bug #25051: lwip_recvfrom problem with udp: fromaddr and
port uses deleted netbuf.
netdb.c: remplace some %#p by %p to be more portable.
init.c: typo
inet.c: patch #6765: Fix a small problem with the last changes (incorrect
behavior, with ip address string not ended by a '\0', a space or a end of line)
netif.c: minor, fix a warning
raw.c, udp.c, init.c, opt.h, ip.h, sockets.h: bug #26309: Implement the
SO(F)_BROADCAST filter for all API layers. Avoid the unindented reception of
broadcast packets even when this option wasn't set. Port maintainers which want
to enable this filter have to set IP_SOF_BROADCAST=1 in opt.h. If you want this
option also filter broadcast on recv operations, you also have to set
IP_SOF_BROADCAST_RECV=1 in opt.h.
dhcp.c, netbios.c: Changes if IF_SOF_BROADCAST is enabled.
CHANGELOG: minor, typo
minor changes: typos and coding style
goldsimon (1255):
tcpip.c: Moved call to ip_init(), udp_init() and tcp_init() from
tcpip_thread() to tcpip_init()
Fix BUG#11400 - don't corrupt existing pbuf chain when enqueuing multiple
pbufs to a pending ARP request
Fixed buf #19168 based on patch by Dmitry Potapov
Corrected patch to bug #19168
fixed compiler warning "initialization dircards qualifiers from pointer
target type"
Reduce code size: don't include code in those files if IP_FRAG == 0 and
IP_REASSEMBLY == 0
Last change (reduce code size if not used) had a bug...
Reverted pbuf_alloc() to REV 1.82
SNMP UDP ports can be configured at compile time
Initialize dhcp timers in tcpip_thread (if LWIP_DHCP) to protect the
stack from concurrent access.
Fixed bug #11400-2: New etharp queueing introduced bug: memp_memory was
allocated too small.
Fixed bug #19251 (missing `const' qualifier in socket functions), to get
more compatible to standard POSIX sockets.
checked in patch #5796: pbuf_alloc: len field claculation caused memory
corruption.
fixed bug #5067 (essentialy a signed/unsigned warning fixed by casting to
unsigned).
Remove warnings: "comparision between signed and unsigned" and
"converting from 'unsigned long' to 'u8_t': possible loss of data"
Remove warning in netif_add(): "converting from 's16' to 'u8_t': possible
loss of data" (static variable netifnum)
Remove warnings: "converting from 'u32_t' to 'u16_t': possible loss of
data": check that received timeout values fit into u16_t.
Removed warning: sizeof() was automatically casted to negative
Free pbuf if pbuf_header() fails
sockets.c Remove "#include <errno.h>" from sockets.c to avoid multiple
Removed printf formatter warning introduced by last check-in (changed
local variable from u32_t to u16_t)
- Changed the names of some variables in SNMP module to avoid them
shadowing each other (which produces a lot of warnings and makes the code hard
to maintain)
Change names of 2 global variables again, as the previous names did not
have lwip-style...
Fix bug #5848: add #if PAP_SUPPORT around the whole file pap.h
Introduced #define LWIP_UNUSED_ARG(x) use this for and
architecture-independent form to tell the compiler you intentionally are not
using this variable. Can be overriden in cc.h.
comment to the last check-in was incomplete: Introduced #define
LWIP_UNUSED_ARG(x) use this for and architecture-independent form to tell the
compiler you intentionally are not using this variable. Can be overriden in
cc.h.
3rd fix for bug #11400 (arp-queuing): More pbufs than previously thought
need to be copied (everything but PBUF_ROM!). Cleaned up pbuf.c: removed
functions no needed any more (by etharp).
Ongoing fix to patch #5822: converted more statements like (void)arg;
into LWIP_UNUSED_ARG(arg);
Changed the comment to pbuf_realloc() that it can't grow (only shrink)
chains to reflect the fact that we decided not to change this.
fix bug #2595: "loopif results
Added some more LWIP_UNUSED_ARG()s
Changed some includes for loopif and added comments
task #6792: added added LWIP_DEBUG_ASSERT(x,y), which triggers #ifndef
LWIP_NOASSERT and #ifdef LWIP_DEBUG
Define ETH_PAD_SIZE after including opt.h to avoid conflict with
lwipopts.h
pbuf_alloc() / pbuf_realloc(): added LWIP_DEBUG_ASSERT() and cast
operator when assigning s32_t to u16_t to get rid of compiler warnings
PBUF_POOL_BUFSIZE: For the default length, alignment check in pbuf_init()
failed.
Checked in patch #5453: removed mutex/other locking stuff if
SYS_LIGHTWEIGHT_PROT=0, moved some pbuf pool logic to static functions
checked in patch #5913: in memp_malloc() we can return memp as mem to
save a little RAM (next pointer of memp is not used while not in pool).
Prototype of igmp_tick() in igmp.h did not match the one in igmp.c
Introduced fast one-entry-cache to speed up ARP lookup when sending
multiple packets to the same host.
Further update to ARP queueing: Changed pbuf_copy() implementation so
that it can be reused (don't allocate the target pbuf inside pbuf_copy()).
Another attempt to fix bug #17922
mem_realloc: Added assert to check that memory is shrinked, not expanded.
If MEM_LIBC_MALLOC==1, allow the defines (e.g. mem_malloc() -> malloc())
to be overriden in case the C-library malloc implementation is not protected
against concurrent access.
Fixed 3 typos of the version checked in yesterday...
Removed unused pbuf stats items
Included patch #5920: Create define to override C-library memcpy. 2
Defines are created: MEMCPY() for normal memcpy, SMEMCPY() for situations where
some compilers might inline the copy and save a function call. Also replaced
all calls to memcpy() with calls to (S)MEMCPY().
Included patch #5448: include '#ifdef __cplusplus \ extern "C" {' in all
header files. Now you can write your application using the lwIP stack in C++
and simply #include the core files. Note I have left out the netif/ppp/*h
header files for now, since I don't know which files are included by
applications and which are for internal use only.
Included opt.h before checking the options.
Added some ASSERTs and NULL-pointer checks to sys_timeout/sys_untimeout
- Changed mem_malloc(): near fit behaves like exact fit since mem->next
is always used
Ooops, checked in the wrong version before :-(
sys.h: moved #include "arch/sys_arch.h" down a little, so that functions
using the defines SYS_ARCH_TIMEOUT/SYS_MBOX_EMPTY can be define as static
(inline) in sys_arch.h. This should not affect any others since the defines
couldn't be overridden anyway...
Fix for bug #19740: 2 static functions are unused, simply ifdefing them
out for now to get rid of warnings
Fixed bug from patch #5865 by moving the defines for socket options
(lwip_set/-getsockopt) used with level IPPROTO_TCP from tcp.h to sockets.h.
Modified struct pbuf size determination so that sizeof(struct pbuf) does
not necessarily be a multiple of MEM_ALIGNMENT
(see task #6831): Included new option PBUF_POOL_USES_MEMP to use a memp
pool for PBUF_POOL pbufs instead of the old pool implementation in pbuf.c to
remove redundant code.
task #6831: removed the option PBUF_POOL_USES_MEMP and removed the old
pbuf pool code, pbuf pool now always allocates from a memp pool
Found a little bug in ARP_QUEUEING: if pbuf_alloc for the packet to be
queued failed, pbuf_copy was called with a NULL pointer.
Aligned MIN_SIZE, memset(0) the complete ram_heap instead of only the
used area, only to be on the safe side...
pbuf_alloc(PBUF_POOL): Added asserts to make sure payload+len is still in
bound of the pbuf (also to make sure bug #15659 is fixed).
Removed semaphores from memp, changed sys_sem_wait calls into
sys_arch_sem_wait calls to prevent timers from running while waiting for the
heap. This fixes bug #19167.
Updated stats.h/.c to reflect the integration of pbuf pool into memp
Removed PBUF_STATS and related code from opt.h & msg_in.c
Finally removed all occurences of PBUF_STATS :-)
If a udp_pcb has a local_ip set, check if it is the same as the one of
the netif used for sending to prevent sending from old addresses after a netif
address gets changed (partly fixes bug #3168).
Fix bug #19729: free pbuf if netif->input() returns != ERR_OK.
changes tabs to spaces
...and again replacing tab by spaces ;-)
tcpip_input()/tcpip_ethinput(): don't free the pbuf if returning ERR_MEM,
that is the netif driver's responsibility
Added comments whether fields are host or network byte order (task #1568)
Added comments whether fields are host or network byte order (task #1568)
Corrected check of PBUF_POOL overflow
Added #if !NO_SYS to most of the api files since they only work with a
sys layer (makes it easier for port projects).
Added some new functions as null-definitions if NO_SYS=1
Addition to patch #5913: decrease size of memp_memory.
Check the user-overridable defines MEMP_SANITY_REGION_BEFORE and
MEMP_SANITY_REGION_AFTER for aligment.
Gave the overflow functions some better names which correspond to the
(future) mem.c function names
Re-included unneeded cases in do_disconnect() and do_send() to prevent
warnings.
Included patch #5938: changed raw_pcb.protocol from u16_t to u8_t since
for IPv4 and IPv6, proto is only 8 bits wide. This affects the api, as there,
the protocol was u16_t, too.
Added some comments, better max-size-check, removed Adams original
mem_malloc.
Broke some (too long) lines down to multiple lines, made the file fit our
coding standards
Included some missing braces in lwip_send & lwip_sendto (if !LWIP_UDP &&
!LWIP_RAW)
Fixed bug #1895 (tcp_bind not correct) by introducing a list of bound but
unconnected (and non-listening) tcp_pcbs.
Removed LWIP_DEBUG_ASSERT
Use TCP_RMV instead of tcp_pcb_remove when removing pcbs from
tcp_bound_pcbs list (bug introduced while fixing bug #1895)
Made etharp_find_addr() use find_entry to concentrate the knowledge of
arp_table layout in find_entry().
Checked in patch #5914: Moved sockopt processing into tcpip_thread.
Done some work on task #1549 (function documentation)
Corrected bug #19937: ICMP assumes p_buf has space for ethernet header.
Allocating new pbuf if the input pbuf isn't big enough.
Done some work on task #1549 (function documentation)
Needed for patch to bug #19937: pbuf_copy is always compiled, not only if
ARP_QUEUEING is enabled
udp_input(): Input pbuf was not freed if pcb had no recv function
registered, p->payload was modified without modifying p->len if sending
icmp_dest_unreach() (had no negative effect but was definitively wrong).
Converted some DEBUGFs that should never happen to LWIP_ASSERTs
Done some work on task #1549 (function documentation)
IPv6: #define IPH_PROTO(hdr) (iphdr->nexthdr) to remove #ifdef IPv6 in
udp_input()
opt.h, ip_frag.c, ip_frag.h, ip.c: Added option IP_FRAG_USES_STATIC_BUF
(defaulting to off for now) that can be set to 0 to send fragmented packets by
passing PBUF_REFs down the stack.
Set q to NULL after freeing it before returning: cleaner code!
Typo in lwip_setsockopt() (getsockopt_internal was called instead of
setsockopt_internal!!!)
Defined IGMP_DEBUG defaulting to LWIP_DBG_OFF in opt.h
Corrected setsockopt for LWIP_IGMP=1 (did not compile & errors were not
returned)
Done some work on task #1549 (function documentation)
Done some work on task #1549 (function documentation) and minor changes

Minor changes to meet coding standard
Fixed a cast warning by including the type to TCP_PCB_COMMON: (Moved
members common to structures tcp_pcp and tcp_listen_pcb into define
TCP_PCB_COMMON (like IP_PCB) to keep (possible) code changes consistent.)
Done some work on task #1549 (function documentation)

Let lookup_group() call lookfor_group() to reduce code size, done some
work on task #1549 (function documentation) and minor changes to meet coding
standard
Done some work on task #1549 (function documentation) and minor changes
to meet coding standard + added some comments to make the code easier to read.
Added define NETIF_INIT_SNMP(type, speed) to initialize per-netif snmp
variables, added initialization of those to slipif and loopif.
loopif_output(): use pbuf_copy() to copy the pbuf to reduce code size
pbuf_copy(): Corrected a wrong comment & try to behave correctly if
LWIP_NOASSERT is defined
Changed define NETIF_INIT_SNMP(type, speed) to include the name of the
struct netif to change...
Done some work on task #1549 (function documentation)
Minor change: don't define some local (unused) variables if
LWIP_TCPIP_CORE_LOCKING=1
Changed etharp_tmr() to be smaller
Modified order of parameters for etharp_output() to match netif->output
so etharp_output() can be used directly as netif->output to save one function
call.
Corrected #if ... when to include copy_from_pbuf()
set netif->output to etharp_output by default to save a function call
Forgot some brackets in an if statement in v1.109
Included switch LWIP_UDPLITE (enabled by default) to switch off UDP-Lite
support if not needed (reduces udp.c code size)
UDP Lite: corrected the use of chksum_len (based on RFC3828: if it's 0,
create checksum over the complete packet. On RX, if it's < 8 (and not 0),
discard the packet. Also removed the duplicate 'udphdr->chksum = 0' for both
UDP & UDP Lite.
Added UDP lite support for sockets
In udp_input, for UDP Lite, chksum_len_tx was used instead of
chksum_len_rx
pcb_new sets conn->err if protocol is not implemented -> netconn_new_..()
does not allocate a new connection for unsupported protocols.
minor fix in assertion text
pbuf_copy: chained pbufs were not copied correctly because of wrong
packet-queue-check
pbuf_copy(): removed copy & paste error which did not copy pbuf chains
correctly
Added debug output for icmp_input if ip_output_if worked or not.
Changed all references to old debug defines to the new ones (e.g.
LWIP_DBG_TRACE)
Fixed bug #20180 (TCP pcbs listening on IP_ADDR_ANY could get changed in
netif_set_ipaddr if previous netif->ip_addr.addr was 0.
Done some work on task #1549 (function documentation), added some
LWIP_ERROR checks, created define instead of extra-function for netconn_new,
netconn_new_with_callback and netconn_err
Created define instead of extra-function for netconn_new,
netconn_new_with_callback and netconn_err, added netconn_type NETCONN_INVALID
Corrected some copy & paste errors
Added comments for the callback functions included in structs tcp_pcb,
udp_pcb and raw_pcb.
Minor fix: coding style
Added comments for the callback functions included in struct
tcp_listen_pcb
Done some work on task #1549 (function documentation), added some
LWIP_ERROR checks, don't call pcb_new() from do_bind() and do_connect() since a
netconn without pcb can't exist any more (after the recent changes to
netconn_new_*())
Done some work on task #1549 (function documentation)
Implemented socket options SO_NO_CHECK for UDP sockets to disable UDP
checksum generation on transmit.
Done some work on task #1549 (function documentation)
Always align PBUF_POOL_BUFSIZE, pbuf_init is not needed any more, minor
changes to meet coding style requirements
In accept_function, one LWIP_ERROR had a wrong expression (since it is
inverted compared to LWIP_ASSERT...)
Done some work on task #6933: converted some LWIP_ASSERTs to LWIP_ERROR
to give back an error return value for LWIP_NOASSERT=1
Done some work on task #6933: converted some LWIP_ASSERTs to LWIP_ERROR
to give back an error return value for LWIP_NOASSERT=1
Forgot to implement getsockopt for SO_NO_CHECK
Corrected two formatters in LWIP_DEBUGF calls
Shortened some lines to ~80
Ooops, checked in a wrong (test-) version before!
Removed warning "empty body in an if statement" in tcp_receive() for
LWIP_DEBUG=0
Changed etharp to use a defined hardware address length of 6 to avoid
loading netif->hwaddr_len every time (since this file is only used for ethernet
and struct eth_addr already had a defined length of 6).
Fixed bug #20021: Moved sendbuf-processing in netconn_write from
api_lib.c to api_msg.c to also prevent multiple context-changes on low memory
or empty send-buffer.
Moved the nagle algorithm from netconn_write/do_write into a define
(tcp_output_nagle) in tcp.h to provide it to raw api users, too.
Corrected do_write for LWIP_TCPIP_CORE_LOCKING=1
Converted the length argument of netconn_write (and therefore also
api_msg_msg.msg.w.len) from u16_t into int to be able to send a bigger buffer
than 64K with one time (mainly used from lwip_send).
Added ASSERT to check that lwip_send(to) is not called for length not
fitting into u16_t (for UDP & RAW sockets)
Introduced the option MEM_USE_POOLS to use 4 pools with different sized
elements instead of a heap. This both prevents memory fragmentation and gives a
higher speed at the cost of more memory consumption. Turned off by default.
ASSERTS were using old MEM_ALIGN define, therefore, was not compilable
without LWIP_NOASSERT defined
no-pool-big-enough was not correctly caught
Changed the expression of LWIP_ERROR to the same as for LWIP_ASSERT
Sorry, checked in some of my local changes with the LWIP_ERROR
modification!
etharp_tmr function had a bug (pending entries were pending for too long)
Combined etharp_request with etharp_raw for both LWIP_AUTOIP =0 and =1 to
remove redundant code.
Moved filling of ethernet header for outgoing IP packets into an extra
function to reduce code size.
Fixed bug #20220: UDP PCB search in udp_input(): a non-local match could
get udp input packets if the remote side matched.
Fixed bug #20253: icmp_dest_unreach was called with a wrong p->payload
for udp packets with no matching pcb.
etharp_arp_input: stricter checking of hwtype, proto, hwlen & protolen
allows us to leave some header fields like they are when sending ARP reply
(only changing the addresses is needed)
Fixed bug #20259: struct udp_hdr was lacking the packin defines.
Removed warning: LWIP_DEBUGF had wrong argument count
Set the err_to_errno_table to be const
Remove warning in tcp_enqueue (cast from u32_t to u16_t)
Fixed minor indentation fault
Fixed bug #20287: Fixed nagle algorithm (sending was done too early if a
segment contained chained pbufs)
Added check to prevent tcp_pcb->snd_queuelen from overflowing.
Set/get ARP hwlen and protolen in one piece.
Fixed a wrong assert statement in etharp_query when ARP_QUEUEING=1 and
packets should be queued.
Changed tcp_pcb->snd_queuelen from u8_t to u16_t to prevent overflowing
when sending many small packets with big send buffer, added assertions and
oveflow checks for snd_queuelen.
Removed warning when assigning from u32_t to u16_t by casting to u16_t.
Fixed a little cast-warning from u32_t to u16_t
Added some ASSERTS and casts to prevent warnings when assigning to
smaller types.
Added option LWIP_NETIF_HWADDRHINT (default=off) to cache ARP table
indices with each pcb instead of single-entry cache for the complete stack.
#ifdef LWIP_NETIF_HWADDRHINT around IP_PCB.addr_hint
Final fix for bug #20021 and some other problems when closing tcp
netconns: removed conn->sem, less context switches when closing, both
netconn_close and netconn_delete should safely close tcp connections.
Bug in last version (fix to close problems): netconn thread might get
active before calling its callback, so conn was already deallocated.
Added assertions where PBUF_RAM pbufs are used and an assumption is made
that this pbuf is in one piece (i.e. not chained). These assumptions clash with
the possibility of converting to fully pool-based pbuf implementations, where
PBUF_RAM pbufs might be chained.
Removed old debug variables from pbuf_copy()
Another change for fixing bug #20478 (put the memp += MEMP_SIZE in
another place)
Included the mem_malloc pools in memp_names if MEM_USE_POOLS=1
Fix bug #20480: Check the pcb passed to tcp_listen() for the correct
state (must be CLOSED).
Fix bug #20506: Slow start / initial congestion window starts with 2 *
mss (instead of 1 * mss previously) to comply with some newer RFCs and other
stacks.
tcp_enqueue: pcb->snd_queuelen didn't work for chaine PBUF_RAMs: changed
snd_queuelen++ to snd_queuelen += pbuf_clen(p).
Fixed bug #20429: use the new pbuf_copy_partial instead of the old
copy_from_pbuf, which illegally modified the given pbuf; Introduced
pbuf_copy_partial, making netbuf_copy_partial use this function.
Another fix for bug #20021: by not returning an error if tcp_output fails
in tcp_close, the code in do_close_internal gets simpler (tcp_output is called
again later from tcp timers).
Added a better comment to explain why tcp_close doesn't care for the
return value of tcp_output
Fixed bug #21107 (didn't reset IP TTL in ICMP echo replies)
Fixed bug #21080 (tcp_bind without check pcbs in TIME_WAIT state) by
checking tcp_tw_pcbs also
Moved ethernet_input from tcpip.c to etharp.c so all netifs (or ports)
can use it.
Changed IP_REASSEMBLY to enqueue the received pbufs so that multiple
packets can be reassembled simultaneously and no static reassembly buffer is
needed.
Check for TCP_SND_QUEUELEN overflow.
Added check for overlapping or duplicate fragments. ip_reass_init() is
not needed any more (the check is done in
chain_frag_into_packet_and_validate()).
Fixed UDPLite SENDING: Checksum was always generated too short and also
was generated wrong if checksum coverage != tot_len.
lfree was not updated in mem_realloc!
Removed type conversion warning in debug statement.
Typo in chain_frag_into_packet_and_validate (but obviously worked
anyway...)
Removed <warning: potential uninitialized reference to
Preprocessor statements have to start at the beginning of a line for old
compilers!
Added todo: free the oldest entry when the MEMP_REASSDATA pool is empty
or the IP_REASS_MAX_PBUFS limit is reached
Fixed UDPLite receive: checksum was calculated wrong if checksum coverage
!= tot_len
Changed initialization: many init functions are not needed any more since
we now rely on the compiler initializing global and static variables to zero!
Forgot two explicit initializations...
Gave the parameters of pbuf_cat() and pbuf_chain() better names to make
the use more clear.
Added description for MEMP_NUM_REASSDATA and changed the default value to
5.
Added check that MEMP_NUM_REASSDATA is bigger than IP_REASS_MAX_PBUFS
(because each MEMP_NUM_REASSDATA has one pbuf at least!)
Added code to free the oldest packets if the IP_REASS_MAX_PBUFS limit is
reached or MEMP_REASSDATA is empty.
Removed bug on memory failure introduced 3 months ago in rev 1.34 (input
pbuf was freed on puf_alloc failure)
IP_REASSEMBLY: Changed 'packet' to 'datagram' to match the names used in
the RFCs
IP_REASSEMBLY: send ICMP time exceeded when discarding datagrams for
which the first fragment was received; try to keep the header of the first
(octet 0) fragment; combined code to make it smaller; fixed bug in timer: when
freeing packets, counter was not updated correctly
Minor coding style fixes, added comment
Removed check for conn->err for functions whose counterparts in api_msg.c
also do the check (1. remove redundant code, 2. check is better done in tcpip
thread context)
Added some explaining comments.
Fixed bug #21181: On active open, the initial congestion window was
calculated based on the configured TCP_MSS, not on the MSS option received with
SYN+ACK.
Fixed bug #21491: The MSS option sent (with SYN) is now based on TCP_MSS
instead of pcb->mss (on passive open now effectively sending our configured
TCP_MSS instead of the one received).
Fixed bug #21494: The send mss (pcb->mss) is set to 536 (or TCP_MSS if
that is smaller) as long as no MSS option is received from the remote host.
Task #7410: Removed the need to include core header files in api.h
(ip/tcp/udp/raw.h) to hide the internal implementation from netconn api
applications.
Patch #6215: added ifAdminStatus write support (if explicitly enabled by
defining SNMP_SAFE_REQUESTS to 0); added code to check link status for
ifOperStatus if LWIP_NETIF_LINK_CALLBACK is defined.
Fixed bug: assert fired when MEMP_ARP_QUEUE was empty (which can happen
any time). Now the packet simply isn't enqueued when out of memory.
tcp_send_ctrl(): call tcp_enqueue with the new flag TCP_WRITE_FLAG_COPY
instead of 1
Turned all hostname variables and parameters into (const char*)
Added sequential dns resolver function for netconn api
(netconn_gethostbyname)
Added sequential (socket API) function gethostbyname and the struct
hostent it uses
Moved inet files into ipv4/ipv6 directory; splitted inet.c/inet.h into
inet and chksum part; changed includes in all lwIP files as appropriate
Deleted old inet.c/inet6.c files
Added thread-safe function gethostbyname_r (as in glibc)
Added function documentation to dns.c, removed function documentation
from dns.h (functions should be documented where they are implemented!),
dns_table_entry doesn't have to be packed (slower, bigger code for most
machines), converted dns_init to return void, dns_table is implicitly
initialized to zero, dns_lookup can be static, dns_send returns correct error
values, added some asserts, compacted dns_recv using some (ugly) gotos,
compacted dns_gethostbyname by combining the same return value
Adopted lwip_gethostbyname and lwip_gethostbyname_r to the new return
values of dns_gethostbyname/netconn_gethostbyname
Added return value comments to netconn_gethostbyname
Fixed bug #20287: tcp_output_nagle sends too early. This fixes the nagle
algorithm; nagle now also works for all raw API applications and has to be
explicitly disabled with 'tcp_pcb->flags |= TF_NODELAY'
Implemented calculating the effective send-mss based on the MTU of the
netif used to send. Enabled by default. Disable by setting
LWIP_CALCULATE_EFF_SEND_MSS to 0. This fixes bug #21535.
tcpip.h was not compilable with both NO_SYS and LWIP_NETCONN set to 0
(include sys.h was missing)
Moved lwip_gethostbyname from sockets.c to the new file netdb.c; included
lwip_getaddrinfo.
Added some documentation (mainly what is unimplemented in contrast to
'std-BSD'), alloc_socket returns the sock pointer directly (for speedup)
Added the wiki and a note about the mailing lists
Added documentation
Added some more comments and function documentation
Back to old alloc_socket(), lwip_accept had a bug in last revision
Added documentation / minor code layout changes
dhcp_unfold_reply() uses pbuf_copy_partial instead of its own copy
algorithm; corrected some assert messages
Fix some warnings discovered by compiling the unixsim under cygwin (gcc
pedantic)
Minor coding style changes, added some comments
Added an explaining comment for the line 'nsock->rcvevent += -1 -
newconn->socket;' in lwip_accept
lock event_callback against lwip_accept for data that arrives right away
after an accept (before lwip_accept has processed the new conn)
initialize netconn->socket to -1 instead of 0 since 0 is a valid socket!
Check state == CLOSED in tcp_bind and tcp_connect to prevent
binding/connecting twice (using LWIP_ERROR: can be disabled)
Fixed bug #21582: pcb->acked accounting can be wrong when ACKs arrive
out-of-order
Minor coding style changes
Implemented new function udp_sendto_if which takes the netif to send as
an argument (to be able to send on netifs that are down).
Changed error handling: ERR_MEM, ERR_BUF and ERR_RTE are seen as
non-fatal, all other errors are fatal. netconns and sockets block most
operations once they have seen a fatal error.
fixed bug #21643 (udp_send/raw_send don't fail if netif is down) by
letting ip_route only use netifs that are up.
mem_malloc with MEM_USE_POOLS=1: if size > size of biggest pool and
custom pools (in addition to the MEM_POOLs) were defined, the first custom pool
was used instead of asserting
Use LINK_STATS_INC instead of #if LINK_STATS...
Use IP_STATS_INC instead of #if IP_STATS...
Use ICMP_STATS_INC instead of #if ICMP_STATS...
Introduced ETHARP_STATS
Minor coding style changes
first attempt to fix bug #21655 (DHCP doesn't work reliably with multiple
netifs): if LWIP_DHCP is enabled, UDP packets to DHCP_CLIENT_PORT are passed to
netif->dhcp->pcb only (if that exists) and not to any other pcb for the same
port (only solution to let UDP pcbs 'bind' to a netif instead of an IP address)
task #7497: Sort lists (pcb, netif, ...) for faster access UDP: move a
(connected) pcb selected for input to the front of the list of pcbs so that it
is found faster next time. Same for RAW pcbs that have eaten a packet.
connect the UDP pcb to the DNS server (IPaddress and port) to receive
faster (unconnected pcbs are very inefficient in udp_input)
Compacted code: moved the code creating a netconn (without pcb) from
netconn_new_with_proto_and_callback to new (synchroneous) function
netconn_alloc_with_proto_and_callback and call this function from
netconn_new_with_proto_and_callback and accept_function.
Minor change: use goto instead of redundant code to return on error in
dhcp_rev().
fix bug #21656 (recvmbox problem in netconn API): always allocate a
recvmbox in netconn_new_with_proto_and_callback. For a tcp-listen netconn, this
recvmbox is later freed and a new mbox is allocated for acceptmbox. This is a
fix for thread-safety and allocates all items needed for a netconn when the
netconn is created.
Minor fix: #include "lwip/api.h" was missing to compile cleanly
fix bug #21654: exclude definition of struct timeval from #ifndef FD_SET.
If including <sys/time.h> for system-struct timeval, LWIP_TIMEVAL_PRIVATE now
has to be set to 0 in lwipopts.h
ip_input: check if a packet is for inp first before checking all other
netifs on netif_list (speeds up packet receiving in most cases)
Added short comment in file description about how to handle MEM_USE_POOLS
/ MEM_LIBC_MALLOC
fix bug #21699 (segment leak in ooseq): add assert that all segment lists
are empty in tcp_pcb_remove before setting pcb to CLOSED state; don't directly
set CLOSED state from LAST_ACK in tcp_process
Fix bug #21699: segment leak in ooseq processing when last data packet
was lost (free last segment if FIN is already received)
Corrected assert when netconn_new_* fails
Removed debug code
sys.h, api_lib.c, api_msg.c, sockets.c: fix bug #21698:
"netconn->recv_avail is not protected" by using new macros for interlocked
access to modify/test netconn->recv_avail.
tcp.h, opt.h, api.h, api_msg.h, tcp.c, tcp_in.c, api_lib.c, api_msg.c,
sockets.c, init.c: task #7252: Implement TCP listen backlog: Warning: raw API
applications have to call 'tcp_accepted(pcb)' in their accept callback to keep
accepting new connections.
Added function netconn_free(), which deallocates all mboxes and frees the
netconn (to be used from different places) - the PCB is not freed!
Coding style: use named constants instead of numbers only
Clarify that timeout == 0 means wait forever
Corrected comment in do_writemore()
fixed bug #22249: division by zero could occur if a remote host sent a
zero mss as TCP option.
Added global #ifndef __SIO_H__ and some comments
fixed bug #21433 (Calling mem_free/pbuf_free from interrupt context isn't
safe): set LWIP_USE_HEAP_FROM_INTERRUPT to 1 in lwipopts.h or use
tcpip_callback_nonblocking(pbuf_free_int, p)/
tcpip_callback_nonblocking(mem_free, m) to free pbufs or heap memory from
interrupt context
Changed the pbuf_free/mem_free callback functions a little: created extra
functions for that
Fixed comments for pbuf_copy() and find_entry() as proposed by Luca
Ceresoli on lwip-users
fixed bug #22804: dhcp_stop doesn't clear NETIF_FLAG_DHCP (flag now
cleared)
Checked in slightly modified version of patch # 6370: Moved loopif code
to netif.c so that loopback traffic is supported on all netifs (all local IPs).
Got the date & place of the newest feature wrong ;-)
Changed loopback code (less difference between NO_SYS = 0 / 1), added
setting LWIP_LOOPBACK_MAX_PBUFS to limit loopback-queued pbufs
Increasing etharp error stats on unsupported ethtype in ethernet_input()
Checked in some ideas of patch #6460 (loop optimizations) and created
defines for swapping bytes and folding u32 to u16.

Added a configuration option for slipif for symmetry to loopif (patch
#6480)
Changed two MEMCPY calls to SMEMCPY
patch #6459: Made err_t overridable to use a more efficient type (define
LWIP_ERR_T in cc.h)
Fixed includes in netif.c, removed loop_cnt_max member in struct netif
(instead the define LWIP_LOOPBACK_MAX_PBUFS is used directly)
Added debug trace for incoming eth packets in ethernet_input like
suggested in patch #6519
patch #6483: stats module improvement: Added defines to display each
module's statistic individually, added stats defines for MEM, MEMP and SYS
modules, removed (unused) rexmit counter.
Fix typo, add comment
fixed bug #21433: Calling mem_free/pbuf_free from interrupt context isn't
safe: LWIP_ALLOW_MEM_FREE_FROM_OTHER_CONTEXT allows mem_free to run between
mem_malloc iterations. Added illegal counter for mem stats.
fixed bug #23847: do_close_internal references freed memory
removed invalid call to tcp_connect() in do_close_internal()
Fixed some warnings, changed some debug defines to include better names
Added 2 asserts in pbuf_realloc to prevent dereferencing a null pointer
in invalid pbuf queues

declaration of struct in_addr from ip_addr.h to inet.h
fixed one small warning (compared u16_t to <= 0)
fixed bug #24517: IP reassembly crashes on unaligned IP headers by
packing the struct ip_reass_helper.
fixed bug ##24596: Vulnerability on faulty TCP options length in
tcp_parseopt
Checked in (slightly modified) patch #6683: Customizable AUTOIP "seed"
address. This should reduce AUTOIP conflicts if LWIP_AUTOIP_CREATE_SEED_ADDR is
overridden.
Corrected the range calculation of LWIP_AUTOIP_CREATE_SEED_ADDR,
corrected comments
Another modification for patch #6683 (Customizable AUTOIP seed address)
patch #6699: fixed some warnings on platform where sizeof(int) == 2
Another fix for bug #6683 (and a typo in changelog)
Reverted last changes since it's wrong when sizeof(int)==2...
fixed bug #25467: Listen backlog is not reset on timeout in SYN_RCVD:
Accepts_pending is decrease on a corresponding listen pcb when a connection in
state SYN_RCVD is close.
Moved INADDR_* defines to inet.h; removing dependency from inet.h to
ip_addr.h
Fixed bug #25544: DHCP_COARSE_TIMER_MSECS could overflow on 16-bit targets
added configurable default valud for netconn->recv_bufsize:
RECV_BUFSIZE_DEFAULT (fixes bug #23726: pbuf pool exhaustion on slow recv())
including inet.h because htonl is used
fixed bug #24480 (releasing old udp_pdb and pbuf in dhcp_start)
added MEMP_MEM_MALLOC to use mem_malloc/mem_free instead of the pool
allocator (can save code size with MEM_LIBC_MALLOC if libc-malloc is otherwise
used)
fixed bug #25345 (DHCPDECLINE is sent with "Maximum message size" option)
Added LWIP_VERSION to get the current version of the stack (implements
task #9032: Provide means to get Version of Stack and submodules)
LWIP_VERSION: corrected shifting for 16-bit platforms, added
LWIP_RC_DEVELOPMENT
Fixed compilation error in LWIP_VERSION
fixed bug #24440: TCP connection close problem on 64-bit host by moving
accept callback function pointer to TCP_PCB_COMMON
fixed arguments of socket functions to match the standard; converted size
argument of netconn_write to 'size_t' for that; fixed some warnings
patch #6539: (configurable) response to broadcast- and multicast pings
etharp_raw: allocating PBUF_RAW for outgoing ARP packets instead of
PBUF_LINK is enough.
Added check: PBUF_POOL_BUFSIZE must be greater than MEM_ALIGNMENT or else
the offset of a pbuf may take the full first pbuf in a chain (resulting in the
first pbuf having len==0)
patch #6528: the buffer used for IP_FRAG_USES_STATIC_BUF could be too
small depending on MEM_ALIGNMENT
Fixed many warnings: use %p to pass pointers to printf
sys_now() must return u32_t, not unsigned long
mem_free: fix a warning by converting pointer to mem_ptr_t instead of
unsigned long
Fixed many LWIP_DEBUGF format strings; added new format string SZT_F for
size_t
cc.h: Added printf formatter for size_t: SZT_F

tcp_listen_input: format code for #if LWIP_TCP_TIMESTAMPS that calls
tcp_enqueue like the other calls.

header pbuf, not the data pbuf); added function comments; "inline" is not
supported by ANSI C (tcp_build_timetamp_option)
Fixed bug #26236: "TCP options (timestamp) don't work with
no-copy-tcpwrite": deallocate option data, only concat segments with same flags
task #7507, patch #6786: DNS supports static hosts table. New
configuration options DNS_LOCAL_HOSTLIST and DNS_LOCAL_HOSTLIST_IS_DYNAMIC.
Fixed bug #26069: Corrected documentation: if tcp_connect fails, pcb->err
is called, not pcb->connected (with an error code).
Fixed some issues with DNS_LOCAL_HOSTLIST
bug #26213 "Problem with memory allocation when debugging": memp_sizes
contained the wrong sizes (including sanity regions); memp pools for
MEM_USE_POOLS were too small; Added option MEM_USE_POOLS_TRY_BIGGER_POOL to try
the next bigger malloc pool if one is empty (only usable with MEM_USE_POOLS).
fixed bug #24212: "Deadlocked tcp_retransmit due to exceeded pcb->cwnd":
Fixed by sorting the unsent and unacked queues (segments are inserted at the
right place in tcp_output and tcp_rexmit)
Fixed a bug in tcp_enqueue introduced with v1.79 of this file while
fixing bug #25094 (zero-length pbuf)

coop-mode
fixed bug #25636: SNMPSET value is ignored for integer fields
fixed tcpip_untimeout (does not need the time, broken after 1.3.0 in CVS
only) - fixes compilation of ppp_oe.c
Fixed bug #26349: Nagle algorithm doesn't send although segment is full
(and unsent->next == NULL)
snmp was not initialized in lwip_init()
Fixed bug #26405: Prematurely released semaphore causes lwip_select() to
crash
Added ip_current_netif() & ip_current_header() to receive extended info
about the currently received packet.

On little endian architectures, use LWIP_PLATFORM_HTONS (if defined) for
SWAP_BYTES_IN_WORD to speed up checksumming.
Added more threading info
Added netbuf.h to files that may be called from any thread
Worked on dns: local host-list can be put into FLASH (by defining storage
target/linker section), external function can be defined for lookup, combined
dns_local_removehostname/removehostaddr to dns_local_removehost
Shrinked ICMP code, added option to NOT check icoming ECHO pbuf for size
(just use it): LWIP_ICMP_ECHO_CHECK_INPUT_PBUF_LEN
task #7013: Added option LWIP_NETIF_TX_SINGLE_PBUF to try to create
transmit packets from only one pbuf to help MACs that don't support
scatter-gather DMA.
Fixed compilation if LWIP_PLATFORM_BYTESWAP && (BYTE_ORDER ==
LITTLE_ENDIAN)
bug #26487: Added ip_output_if_opt that can add IP options to the IP
header (used by igmp_ip_output_if)

PPP (for now).
Added newline to TCP header flags debug print

pbuf in UDP receive callback) as it made more problems than before :-(
patch #6888: Patch for UDP Netbufs to support dest-addr and dest-port
patch #6930: [PATCH trivial] TCP_RMV remove unnecessary check - removed
two checks for NULL which are not necessary.
Updated comment in low_level_input() about pbuf len vs. tot_len if using
preallocated pbufs (as requested in bug #27576: pbuf_realloc will assert or
crash on a non-chained pbuf list)
Accidentally endabled to compile the code -> back to #if 0
Fixed default values of some stats to only be enabled if used Fixes bug
#27338: sys_stats is defined when NO_SYS = 1

Fixed bug #27704: autoip starts with wrong address:
LWIP_AUTOIP_CREATE_SEED_ADDR() returned address in host byte order instead of
network byte order

directly returning when sys_arch_mbox_fetch times out.
Fixed bug #27329: dupacks by unidirectional data transmit
Fixed bug #27390: Source IP check in ip_input() causes it to drop valid
DHCP packets -> allow 0.0.0.0 as source address when LWIP_DHCP is enabled
Fixed bug #27315: zero window probe and FIN
Corrected typo
Fixed bug #27215: TCP sent() callback gives leadin and trailing 1 byte
len (SYN/FIN)
dhcp_inform(): netif->dhcp pointed to unallocated memory when udp_new()
failed
dhcp_unfold_reply: NULL memory might have been freed after mem_malloc
returned NULL
Removed most calls to udp_connect since they aren't necessary when using
udp_sendto_if() - always stay connected to IP_ADDR_ANY.
Minor code simplification (don't store received pbuf, change conditional
code to assert where applicable), check pbuf length before testing for valid
reply
bug #27315: zero window probe and FIN: only send pure FIN if the enqueued
FIN segment doesn't contain any other data
Changed fix for bug #27215 (TCP sent() callback gives leagin and trailing
1 byte len (SYN/FIN)) by decreasing pcb->acked appropriately
Fixed bug #26251: RST process in TIME_WAIT TCP state
Fixed bug #27783: Silly window avoidance for small window sizes
Another fix for bug #26251: RST process in TIME_WAIT TCP state
Minor: fixed typo
bug-fix in the TCP_EVENT_RECV macro (has to call tcp_recved if pcb->recv
is NULL to keep rcv_wnd correct)
Improved heap usage of lwip_getaddrinfo by only allocating one block of
memory per call.
Tiny code size improvement using goto instead of duplicating code
Minor: Improved memory layout/alignment of struct dhcp for 32-bit
platforms
Added netifapi_netif_set_addr()
Corrected parameter spelling in doc
Fixed wrong filename
Increased default value for TCP_MSS to 536, updated default value for
TCP_WND to 4*TCP_MSS to keep delayed ACK working.
Fixed bug #27994: incorrect define for freeaddrinfo(addrinfo)
Fixed bug #28062: Data received directly after accepting does not wake up
select
Fixed comment: tcp_pcb_remove does *not* deallocate the pcb
tcp_input: move tcp_debug_print_state to prevent accessing pcb when it
might already be deallocated due to calling tcp_abort in tcp_process.
Clarified debug levels by renaming level OFF to ALL (the old define still
exists for now to prevent breaking old code)
Fixed usage of logging levels (bug #27948: Incorrect logging levels used
in various places)
Fixed usage of logging levels (bug #27948: Incorrect logging levels used
in various places)
Fixed logging of timeout-function-pointer (pointer to local stack was
logged instead of actual function pointer), minor coding style fix
move tcp_debug_print_state to prevent accessing pcb when it might already
be deallocated due to recv_flags == TF_RESET or TF_CLOSED
Fixed bug #28049 (Keep Alive timeout frees pcb then uses it, sometimes
causing crash error) by calling tcp_rst() instead of tcp_abort() in
tcp_slowtmr() when retransmit timer expires.
Fixed bug #27955: netconn_close may nether return when
LWIP_TCPIP_CORE_LOCKING enabled
tcp_recv_null: call tcp_recved() if p != NULL to keep the window correct
Fixed bug #27851 (TCP_EVENT_RECV(pcb, NULL,...) results in unreachable
code warning) by calling tcp_recv_null if pcb->recv is null.
tcp_alloc: prevent increasing stats.err for MEMP_TCP_PCB when reusing
time-wait pcb as suggested by Bill 4 months ago
Fixed bug #27905: FIN isn't combined with data on unsent
Fixed filename in last comment
Fixed bug #28099 (API required to disable Nagle algorithm at PCB level):
added tcp_nagele_*() function-like macros
Got the tcp_nagle_*() defines wrong (inverted) :-(
Fixed bug #28098: Nagle can prevent fast retransmit from sending segment
by basing the nagle-decision on TF_INFR also
tcp_rexmit(): no need to call tcp_output, since always called from
tcp_input and thus tcp_output always returns without sending (prevent confusion
by thinking data was sent while in tcp_rexmit!)
Initial check-in of some unit tests
Fixed bug #28064: pbuf_alloc(PBUF_POOL) is not thread-safe by queueing a
call into tcpip_thread to free ooseq-bufs if the pool is empty
Worked on tcp_oos unit tests, nearly all TCP_QUEUE_OOS code is covered now
Fixed bug #28054: Two segments with FIN flag on the out-of-sequence

Moved the function definitions so that other modules can use the ICMP
protocol header definitions when LWIP_ICMP==0

PPP: Make MAXNAMELEN/MAXSECRETLEN overridable in lwipopts.h
patch #6969: PPP: missing PAP authentication UNTIMEOUT
Sligthly reordered struct netif's members to better meet alignment
requirements
Fixed checking input packet length (20 bytes is a valid packet and is
used e.g. with MS RAS server)
pppInit: Remove zeroing the stats - no protocol does that
Fixed bug #27079 (Yet another leak in PPP): outpacket_buf can be
statically allocated (like in ucip)
tcp_process: add state info to log message that is used for multiple
states ("TCP connection closed")
Various small improvements from patch #6965 (removed _inet_ntoa, set PPP
netif down before removing, change log message and comment)
Added description about the PPP stack

Updated comments on which sio-functions are used
Added explicit check for number of segments and seqno/len of each segment

& data and with FIN alone
Another fix for bug #28241 (ooseq processing) and adapted corresponding
unit test
Added an additional option LWIP_ETHERNET to support ethernet without ARP
(necessary for pure PPPoE) - no changes in the ppp code yet

Removed unused test function
Remove warning for TCP_LISTEN_BACKLOG==0
Reorganised PPP source code from ucip structure to pppd structure to

tcpip-thread. This also makes PPPoE usable with NO_SYS==1
Renamed PPP tasks from "pppMain" to "pppInputThread"
Initial version of PPP for NO_SYS==1, some TODOs are remaining, but it
works...
Fixed bug #28496: missing include guards in netdb.h
Call tcp_timer_needed() with NO_SYS==1, too
Improved assertion message when MEMP_SYS_TIMEOUT pool is empty
Added function names to timer debug output

patch #6822 (Add option to place memory pools in separate arrays) - new
config option MEMP_SEPARATE_POOLS
GCC didn't like memp_memory_XXX -> now using memp_memory_XXX_base (as in
Bill's original patch)
Minor coding style changes, added assertion

netif_set_down() from netif_remove()
Fixed bug #28506 (raw_bind should filter received packets)
Fixed comment on struct mem.prev
Fixed bug #28551 (Compiler warning introduced with closed bug #28506)
Fixed bug #13315 (PPP PAP authentication can result in erroneous
callbacks) by copying the code from recent pppd
Added comments
Fixed NO_SYS==0: starting pppInputThread failed; fixed some comments
Minor speedup ip_output_if when writing TTL/proto to ip header
The heap now may be moved to user-defined memory by defining
LWIP_RAM_HEAP_POINTER as a void pointer to that memory's address (patch #6966
and bug #26133)
Minor fix: bug #28555: Retransmission timer only stopped if
TCP_QUEUE_OOSEQ==1
Coding style
Again: Fixed bug #26672 (close connection when receive window = 0) by
correctly draining recvmbox/acceptmbox
Another fix for bug #28562: Segfault @ err_tcp
do_connect(): set conn->err to an error if conn->pcb is NULL
Improved includes in snmp
Use protocol definition from tcp.h, not from sockets.h
Using typedefs for function prototypes and -pointers throughout the stack
for clarity
Fixed bug #27856: PPP: Set netif link- and status-callback by adding
ppp_set_netif_statuscallback()/ppp_set_netif_linkcallback()
Changed netconn_recv() and netconn_accept() to return err_t (bugs #27709
and #28087)
Minor: source code layout

warnings)
Minor: source code layout
Only check for LWIP_RAND() if IGMP is used, for now
Fixed bug #28679: mem_realloc calculates mem_stats wrong and added test
case for it
reorganised PPP sourcecode to 2.3.11 including some bugfix backports from
2.4.x.
Fixed bug #27316 (netconn: Possible deadlock in err_tcp) by using
sys_mbox_trypost in err_tcp
Added missing include
Fixed netconn_err() macro
Removed unused function declaration for netbuf_len (is a macro now)

Fixed compilation for LWIP_TCPIP_CORE_LOCKING
bug #26523: Compiler Warnings
bug #26523: Compiler Warnings
Renamed the private mib node from 'private' to 'mib_private' to *not* use
reserved C/C++ keywords, added comments, added init-define for private MIB
Renamed the private mib node from 'private' to 'mib_private' to *not* use
reserved C/C++ keywords
bug #28659: Missing casts
Added one more missing cast
Partly fixed bug #22070 (MIB_OBJECT_WRITE_ONLY not implemented in SNMP):
write-only or not-accessible are still returned by getnext (though not by get)
Moved missing include
Use memp pools for snmp instead of the heap; added 4 new pools.
Fixed bug #27871: Calling tcp_abort() in recv callback can lead to
accessing unallocated memory. As a consequence, ERR_ABRT means the application
has called tcp_abort()!
snmp_recv: don't peek the UDP header, p->tot_len does the same; no need
for the extra checks at the beginning; don't use so many if/else but if/return
instead to make the code more readable
Added TCP_SNDQUEUELOWAT corresponding to TCP_SNDLOWAT and added
tcp_sndqueuelen() - this fixes bug #28605
For wrong configurations, let the test fail instead of the compiler
Keep 'const' of varius snmp structs the same throughout 'derived structs'
Added missing casts (bug #28659)
renamed netif pointer in struct igmp from 'interface' to 'netif' to not
use keywords (or at least my editor highlights it as one...); minor layout
change
igmp related: renamed netif pointers from 'interface' to 'netif' to not
use keywords (or at least my editor highlights it as one...)
Cleanly separate the portability file inet.h and its contents from the
stack: moved htonX- functions to def.h (and the new def.c - they are not ipv4
dependent), let inet.h depend on ip_addr.h and not the other way round. This
fixes bug #28732.
Added comments
Add non-blocking support for connect (partly from patch #6860) plus many
cleanups in socket & netconn API
Added function-like macro for struct netconn::non_blocking
Replaced tabs with spaces
Added except set support in select (patch #6860)
Moved freeing a socket to its own function (free_socket, like alloc_socket
Use SYS_LIGHTWEIGHT_PROT instead of a semaphore to protect the sockets
array since the protection time is short
Updated comment about recv_bufsize
Don't call the link-callback from netif_set_up/down() since
Reworked the code that parses DHCP options: parse them once instead of
parsing for every option. This also removes the need for mem_malloc from
dhcp_recv and makes it possible to correctly retrieve the BOOTP file.
Don't parse broadcast option, we don't use it anyway (made up from ipaddr
and netmask), layout change of struct dhcp
Prevent mem_malloc in dhcp_inform, fix check for subnet mask (remember if
it was given by server or not) set back request_timeout in dhcp_set_state()
Prevent mem_free (leave struct dhcp allocated on dhcp_stop) to prevent
calling mem_malloc when restarting dhcp later
Let netdb use a memp pool for allocating memory when getaddrinfo() is
called.
Fixed an error in dhcp_free_request() from dhcp_inform()
Fix handling of zero-padding and parse file before sname field (if
overloaded, according to the RFC)
Fixed compiler warnings when MEM_SIZE < 64000
Added an own debug-print option for timers.c (used TCPIP_DEBUG and
SYS_DEBUG as the code was copied from there)
Use macros defined in ip_addr.h (some of them new) to work with IP
addresses (preparation for bug #27352 - Change ip_addr from struct to typedef
(u32_t) - and better code).
Accidentally changed the member name of struct ip_addr for testing...
Replaced struct ip_addr by typedef ip_addr_t to make changing the actual
implementation behind the typedef easier.
Added missing casts to suppress compiler warnings
Use macros to compare IP addresses
Added missing casts to suppress compiler warnings (this mainly satisfies
MSVC - the double casts are a bit ugly but don't hurt...)
Fixed another compiler warning (missing cast)
Added function-like macros to get/set the hostname on a netif
Correctly initialize netif flags in pppifNetifInit
Fixed compiler warnings
Fixed macro ip_addr_set_loopback(): htonl was missing (fixes bug #28828:
ip_addr.h some macro error)

accept()) introduced a week ago while implementing non-blocking connect
Minot: Fixed comments and code style
Minor: removed one space
Minor: source code layout
Added yet another IP-address-modifying define, ip_addr_set_any()
Reduced the time SYS_ARCH_PROTECT is protecting the socket array
Fixed bug #28798 (Error in "Max Response Time" processing) and another
bug when LWIP_RAND() returns zero.
Improved IGMP stats (patch from bug #28798)
added netif_s/get_igmp_mac_filter() macros
Moved most defines from igmp.h to igmp.c for clarity since they are not
used anywhere else; removed some function prototypes from igmp.h, too
Internalize another function; use the supplied max_response_time instead
of dividing it by 2
Added reentrant versions of inet_ntoa/ipaddr_ntoa
inet_ntoa_r/ipaddr_ntoa_r
Fixed a missing cast warning
Minor: Fixed indentation after changing struct ip_addr to ip_addr_t
Fixed copying multiple IP addresses from options (e.g. multiple DNS
servers) - the amount copied was correct, but the value copied was always the
first.
task #10153 (Integrate loopif into netif.c) - loopif does not have to be
created by the port any more, just define LWIP_HAVE_LOOPIF to 1.
Fixed unit tests after changing struct ip_addr to ip_addr_t
For loopback packets, adjust the stats- and snmp-counters for the
loopback netif.
Fixed compilation for NO_SYS==1
Added function sys_restart_timeouts() from patch #7085 (Restart system
timeout handling)
task #10154 (PPP: Update snmp in/out counters for tx/rx packets)
Merge 3 u8_t for netconn-internal status into one u8_t 'flags' to prevent
waisting memory when adding more flags
Fixed bug #28853 (lwip_recvfrom() returns 0 on receive time-out or any
netconn_recv() error)
Another fix for bug #28853 (recv returns 0 on recv-timeout or any other
error), fixed err_to_errno_table: ERR_TIMEOUT is EWOULDBLOCK, not ETIMEDOUT
Fixed bug #22110 (recv() makes receive window update for data that wasn't
received by application); added function-like macros to correctly access/change
conn->recv_timeout and conn->recv_bufsize
Use sys_arch_sem_wait instead of sys_sem_wait_timeout (same function,
different name)
Removed sys_sem_wait_timeout, added comments to the port-supplied
sys(-arch)-functions
Fixed wrong printf formatter
Removed invalid assert (always true)
Fixed a compiler warning (comparison between signed and unsigned)
Fixed bug #28866 (mem_realloc function defined in mem.h)
Use braces for if blocks
struct netconn.socket is only used with LWIP_SOCKET; added comments
task #10139 (Prefer statically allocated memory): converted mbox and
semaphore functions to take pointers to sys_mbox_t/sys_sem_t; converted
sys_mbox_new/sys_sem_new to take pointers and return err_t; task #7212: Add
Mutex concept in sys_arch (define LWIP_COMPAT_MUTEX to let sys.h use binary
semaphores instead of mutexes - as before)
Fixed compilation for NO_SYS==1
Added comment about mem_realloc() vs. realloc()
Fixed bug #28865 (Cannot close socket/netconn in non-blocking connect)
patch #6865 (SO_REUSEADDR for TCP): if tcp_pcb.flags has TF_REUSEADDR
set, allow binding to endpoint in TIME_WAIT
Fixed comment to our flag names
Code layout: splitted long line
patch #6865: use so_options SOF_REUSEADDR instead of flags TF_REUSEADDR
(which has ben removed again)
task #10139 (Prefer statically allocated memory): added
autoip_set_struct() and dhcp_set_struct() to let autoip and dhcp work with
user-allocated structs instead of callin mem_malloc
netif_set_link_up/down: only do something if the link state actually
changes
Fixed indentation
Added a minimal version of posix fctl() to have a standardised way to set

Add a new err_t, ERR_WOULDBLOCK in preparation for non-blocking send
task #7865 (implement non-blocking send operation)
Fixed old comments
Added stats for mutexes
Use checksum algorithm 2 as default as it should be faster than 1 on most
(if not all) platforms
Fixed compiler warnings for checksum algorithms 2 and 3
struct ip_hdr: split u16_t _ttl_proto to u8_t _ttl and u8_t _proto to
prevent unnecessary loading and htons
fixed compilation for LWIp_SNMP && PPP_INPROC_MULTITHREADED
Improved some defines working on ip addresses, added faster macro to copy
addresses that cannot be NULL
Use new macro ip_addr_copy where applicable
Minor speedups: use ip_addr_copy, use SMEMCPY, use htonX on constants
instead of variables
Use pointers instead of using SMEMCPY
Revert my last changes and remove structure packing from struct dns_query
and struct dns_answer since they are only used with SMEMCPY
Documented the use of netif flags
Fixed bug #28183 (ARP and TCP/IP cannot be disabled on netif used for
PPPoE) by adding a new netif flag (NETIF_FLAG_ETHERNET) that tells the stack
the device is an ethernet device but prevents usage of ARP (so that
ethernet_input can be used for PPPoE).
Fixed ARP input processing: only add a new entry if a request was
directed as us (RFC 826, Packet Reception), otherwise only update existing
entries; internalized some functions
Disable ETHARP_TRUST_IP_MAC by default since it slows down packet
reception and is not really necessary
Fixed bug #28877 (Duplicate ARP gratuitous packet with
LWIP_NETIF_LINK_CALLBACK set on) by only sending if both link- and admin-status
of a netif are up
Link status does not depend on LWIP_NETIF_LINK_CALLBACK (fixes bug #28899)

tcp_seg(s)_free: remove return value, noone uses it
Bug #28917: don't increase error counters for icmp echo response

changed comments and source code layout
Fixed pcb leak when accept-callback is NULL and asserts are disabled
Task #10088: Correctly implement close() vs. shutdown(). Now the
application does not get any more recv callbacks after calling tcp_close().
Added tcp_shutdown().
Use tcp_debug_state_str() instead of tcp_debug_print_state()
Moved stack-internal parts of tcp.h to tcp_impl.h, tcp.h now only
contains the actual application programmer's API
task #10140: Remove DNS_USES_STATIC_BUF (keep the implementation of
DNS_USES_STATIC_BUF==1)
Added const char* name to mem- and memp-stats for easier debugging.
Added define LWIP_TCPIP_CORE_LOCKING_INPUT that lets tcpip_input omit the
thread-change to tcpip_thread and instead lock the core
Corrected comment

appropriate to reflect the variable type
Added a note about socket recv/accept timeout errno value
PPP: use LWIP_DEBUGF() instead of ppp_trace()
Fixed accessing invalid memory when closing a listening pcb (introduced
with tcp_shutdown)
tcp_connect: send timestamp-option only if (pcb->flags & TF_TIMESTAMP) !=
NULL (same as for passive open)
Added comment after #endif
task #7040 (Work on tcp_enqueue): Don't waste memory when chaining
segments, added option TCP_OVERSIZE to prevent creating many small pbufs when
calling tcp_write with many small blocks of data. Instead, pbufs are allocated
larger than needed and the space is used for later calls to tcp_write.
Correctly set TCP_WRITE_FLAG_MORE when netconn_write is split into
multiple calls to tcp_write.
Fixed bug #29072: Correctly set ciaddr based on message-type and state.
Renamed dhcp_create/delect_request to dhcp_create/delete_msg.

Correctly identify link-local addresses when sending ARP packets
Don't try to forward link-local addresses
renamed struct lwip_socket to struct lwip_sock to avoid duplicate names
(function lwip_socket)
task #10167 (sockets: speed up TCP recv by not allocating a netbuf):
added function netconn_recv_tcp_pbuf() for tcp netconns to receive pbufs, not
netbufs; use that function for tcp sockets.
LWIP_TCPIP_CORE_LOCKING_INPUT needs LWIP_TCPIP_CORE_LOCKING to work
correctly
LWIP_NETIF_TX_SINGLE_PBUF needs TCP_OVERSIZE >= TCP_MSS for TCP
Fixed LWIP_NETIF_TX_SINGLE_PBUF for LWIP_TCPIP_CORE_LOCKING
task #7013 (Create option to have all packets delivered to netif->output
in one piece): Always copy to try to create single pbufs in tcp_write.
tcp_accepted(): check pcb state to verify it isn't called on a
connection-pcb
Use braces for if-blocks
Create mem_mutext at the end of mem_init. This enables sys_mutex_new to
use the heap if required.
bug #28775 (select/event_callback: only check select_cb_list on change)
plus use SYS_LIGHTWEIGHT_PROT to protect the select code. This should speed up
receiving data on sockets as the select code in event_callback is only executed
when select is waiting.
Only add hostname if it's not empty (strlen > 0)
Added/corrected casts
bug #29105: Review printf formatters: added X8_F to cc.h and use it in
etharp.c
bug #29105: Review printf formatters
task #10241 (AutoIP: don't break existing connections when assiging
routable address): when checking incoming packets and aborting existing
connection on address change, filter out link-local addresses.
ip_input: better check for old link-local-address (explicitly check for
autoip->llipaddr instead of letting all link-local-addresses through)
Added comment, use braces for single-line if-blocks
ip_output: assert for p->ref == 1 to catch TCP retransmissions where the
netif hasn't freed the pbuf yet
Renamed tcp_output_set_header to tcp_output_alloc_header and included
more code common to all callers
Use a union to let struct sockaddr have the same alignment requirements
as struct sockaddr_in
Temporary upgrade helper: define format string for u8_t as hex if not
defined in cc.h
Fixed some issues in the TCP_OVERSIZE code:
Corrected comment
Reverted the change in struct sockaddr since it wasn't compatible to the
standard (bug #29210)
Some fixes to the TCP_OVERSIZE code:
Fix calculation of tcp_mss(): when timestamps are on, this is pcb->mss -
12 or else NOCOPY-apps might generate unperformant PBUF_REF chains
Fixed sending one byte of data in tcp_zero_window_probe (which I
accidentally broke with v1.103)
Bug #29210: check alignment of struct sockaddr vs. struct sockaddr_in
Fixed bug #29148 (Incorrect PBUF_POOL_BUFSIZE for ports where
ETH_PAD_SIZE > 0) by moving definition of ETH_PAD_SIZE to opt.h and basing
PBUF_LINK_HLEN on it.
Prepared for checksum-on-copy (task #6849):
task #6849: Calculate checksum when creating TCP segments, not when
(re-)transmitting them.

Fixed alignment warnings when we know alignment is correct (by using
LWIP_MEM_ALIGN)
Fixed compiler warnings when casting where we know the source is aligned
(by casting to void-pointer first)
Added missing casts, use strlen + MEMCPY instead of strcpy (as that might
overrun the buffer)
Fixed bug #29256: SNMP Trap address was not correctly set
Corrected spelling of milliseconds (my dictionary tells me to use two l's
:)
Added support for static ARP table entries (added option
ETHARP_SUPPORT_STATIC_ENTRIES) (+ added test); refactored the etharp code a bit

Make LWIP_NETIF_TX_SINGLE_PBUF work for TCP, too
patch #7130: remove meaningless const qualifiers
Speedup TX by moving code from find_entry to etharp_output/etharp_query
to prevent unnecessary function calls (inspired by patch #7135).

create a new (contiguous) PBUF_RAM for every outgoing fragment if
LWIP_NETIF_TX_SINGLE_PBUF==1
patch #7143: Add a few missing const qualifiers

Create overridable macros for copying 2-byte-aligned IP addresses and MAC
addresses
fixed a type
task #6849: added udp_send(_to/_if) functions that take a precalculated
checksum, added pbuf_fill_chksum() to copy data into a pbuf and at the same
time calculating the checksum for that data

Free NAT entries on remove (fixes a memory leak)
.. and deleted NAT again as Christian obviously didn't have the copyright
on the code he sent us... THANKS!!!

interface (by using multiple netifs, each with its own IP)
Fixed bug #29855: PPP: Backport a bugfix in LcpSendEchoRequest from pppd
auth_withpeer_fail(): call lcp_close(), like pppd 2.4.5 does
Fix printf-formatter for sio_fd_t/size_t

task #6995: Implement SO_REUSEADDR (correctly)
SO_REUSEADDR / SO_REUSE is implemented and safe to use
Added new option SO_REUSE_RXTOALL to pass received UDP
broadcast/multicast packets to more than one pcb
SO_REUSE: tcp_listen/tcp_connect: make sure that the 5-tuple is unique
SO_REUSE: tcp_input: correctly handle multiple pcbs listening on the same
port (but different address): first search for a specific address an only pass
to ANY if no specific address has been found listening
udp_input: use SO_REUSE && SO_REUSE_RXTOALL to copy incoming
(broad-/multicast) data to additional pcbs
Removed unused SOF_* flags, ip_pcb.so_options can now be an u8_t instead
of an u16_t (saves 3 bytes per pcb on a 32-bit platform)
udp_input/SO_REUSE_RXTOALL: only call pbuf_header if there is a 2nd pcb
to pass the data to
Fix compilation for LWIP_EVENT_API==1 (unused args)

(sc_service_name/sc_concentrator_name)
Use a simple linked list (next pointer) instead of sys/queue.h (from BSD)
PPPoE now uses its own MEMP pool instead of the heap (moved struct
pppoe_softc from ppp_oe.c to ppp_oe.h)
No need to call pppoe_init any more (since the linked list is implicitly
initialized to zero by the loader)

already defined" i.e. when linking to winsock
Added PP_HTONx/PP_NTOHx macros that can be calculated by the preprocessor
(used for constants only)

link-layer-addressed UDP traffic to be received while a netif is down (just
like DHCP during configuration)
fixed typos that MSVS did not complain about
Fixed bug #30159: WomnIP_ACCEPT_LINK_LAYER_ADDRESSING
nicer code for the last fix
Fixed bug #29361 (ip_frag has problems with zero-copy DMA MACs) by adding
custom pbufs and implementing custom pbufs that reference other (original)
pbufs. Additionally set IP_FRAG_USES_STATIC_BUF=0 as default to be on the safe
side.
Fixed bug #10088: Correctly implemented shutdown at socket level.
From patch #7221: added flag NO_SYS_NO_TIMERS to drop timer support for
NO_SYS==1 for easier upgrading
Fixed compilation error due to unexpected include order

pointers, only function names), changed parameter names from 'h' to 'handler'
fixed bug #30300 (shutdown parameter was not initialized in
netconn_delete)
Added some helper functions to find strings in chained pbufs

introduced while mergin IPv4 and IPv6
Fixed bug #33672 (checksum calculate error!!!) by folding 'acc' to u16_t

fixed bug #34684: Clear the arp table cache when netif is brought down
fix compilation of ip_canforward on 8-/16-bit platforms (where constants
are 16-bit and thus cannot be left-shifted by 24)

fixed bug #35305: pcb may be freed too early on shutdown(WR)
fixed bug #35435: No pcb state check before adding it to time-wait queue
while closing
tcp pcb: persist_cnt can be u8_t instead of u32_t (since it is compared

test_tcp_new_counters_pcb() after adding snd_wnd_max to struct tcp_pcb.
Minor: cosmetic source code layout changes
unit tests lwipopts.h: NO_SYS==1, disable netconn and sockets (not tests)

are unique -> no need to add 3 directories to the include path when compiling
lwIP
added optional macros PACK_STRUCT_FLD_8() and PACK_STRUCT_FLD_S() to
prevent gcc 4 from warning about struct members that do not need packing
update CHANGELOG and fix coding style (fixed bug #39355 SNMP Memory Leak
in case of error)
fixed bug #43389 dns_recv() res_idx calculate error
fixed bug #38219 Assert on TCP netconn_write with sndtimeout set
Merge branch 'master' of git.sv.gnu.org:/srv/git/lwip

lwip_socket_init() is not needed any more -> compatibility define
CHANGELOG: fixed date

IP6H_VTCFL_SET())
sockets.c: fixed using unsigned constant 'FIONBIO' in switch on (signed)

(just introduced that bug this weekend...)
memp: also export memp_sizes[] if MEMP_USE_CUSTOM_POOLS==1
fixed bug #37614 "Errors from ipX_output are not processed". Now
tcp_output(_segment) checks for the return value of ipX_output and does not try

Many const fixes throughout the stack (although these are not all, yet)
revert accidentally committed snmp header files
fixed compiling icmp.c (variable has to be declared at the beginning of a
scope)

leave away the "if != NULL" check to get rid of gcc "-Waddress" warnings in the
core code at least (I might not have caught all of them, yet)
fixed typo in sockets.h
igmp.c: fixed -Waddress, removed dead code
fixed missing casts found with msvc /Wall
sockets.c: added missing casts after changing storage type of 'err'

fixed ip_addr_islinklocal macro definition
more "const" fixes
fixed "missing braces around initializer" for IN6ADDR_*_INIT macros
changed dhcp state name defines to include "STATE_" to prevent confusion
with message types (e.g. INFORMING vs. INFORM)

bug #38204)
Fixed bug #45161 tcp.c / tcp_abandon / pcb->local_port set to zero but
needed later for tcp_rst (introduced some months ago when fixing bug #42299)
fixed bug #45135 getsockopt SO_SNDTIMEO, SO_RCVTIMEO broken
Fixed bug #45098 ip_addr_t type field not populated for socket address
copies (patch by James Smith)

Fixed warnings about NULL check not required (ip_addr_isany) and implicit
conversion (~)
Fixed ~ warnings in a different way
added lwip_socket_thread_init/cleanup to use
LWIP_NETCONN_SEM_PER_THREAD/LWIP_NETCONN_FULLDUPLEX without including anything

netif_find(): name parameter can be const
we are moving towards 1.5.0 -> set LWIP_VERSION accordingly
Fixed that netconn_thread_cleanup() did not call
LWIP_NETCONN_THREAD_SEM_FREE() (!= vs ==)
fix that LWIP_MULTICAST_TX_OPTIONS must be used in ip4_route instead of
LWIP_IGMP
accidentally committed debug comment //
another fix for LWIP_MULTICAST_TX_OPTIONS: without LWIP_IGMP,
udp_pcb->mcast_ttl was not initialized
LWIP_NETCONN_SEM_PER_THREAD: ensure sys_sem_valid() is only called for
non-NULL pointers (not all ports might check this)
fixed bug #45004: dns response without answer might be discarded
dns.c: fixed compiler warning
Add doxygen config + main-file used by Frédéric to create
http://www.nongnu.org/lwip/ for 1.3.0 (see
https://lists.gnu.org/archive/html/lwip-users/2013-01/msg00062.html) - just so
that it doesn't get lost
fixed bug #43790: Sending octet string of Length >255 from SNMP agent
(patch by Manoj Kumar)
fixed passing u16_t 'snmp_varbind->value_len' to functions taking an u8_t
only
Fixed compiler warning when window scaling is enabled (tcp_sndbuf()
should still return u16_t since that value can directly be passed to
tcp_write())
SNMP: tiny preparation for SNMP to support more versions than just v1:
store request version in struct snmp_msg_pstat so that the response can be sent
with the same version (v2c might already work but getbulk is missing)
Clarify comment for MEMP_NUM_SNMP_VARBIND/MEMP_NUM_SNMP_VALUE

parameter matches the pcb type
Fixed UDP multicast receive filtering (multicast should only be received
when bound to ANY or the destination multicast address)
TCP window scaling: don't parse window scaling option on retransmission
ethernet_input: pass IPv4 packets to ip4_input, not to ip_input
PBUF_REF with "custom" pbufs is now supported for RX pbufs (see pcapif in
contrib for an example, LWIP_SUPPORT_CUSTOM_PBUF is required)
fixed pointer type of value passed for snmpenableauthentraps (broken in
2010)
task #12243: DNS/IPv6: added support for AAAA records
worked on task #12243 (Add support for AAAA/IPv6 records to DNS)
Separate mib2 counter/table callbacks from snmp agent. This both cleans
up the code and should allow integration of a 3rd party agent/mib2.

the original const'ness
Fixed ETHARP_TRUST_IP_MAC after changing struct netif.ip_addr/netmask to
ip_addr_t
struct udp_pcb.multicast_ip must be an ip_addr_t, too, to completely
avoid temporary storage

this isn't followed, tcp can get stuck when ACKs don't come through - unless
some PBUF_POOL pbufs are reserved for such RX)
fixed bug #46145 tcp_send_empty_ack() uses wrong netif with
LWIP_HOOK_IP4_ROUTE_SRC (patch by Milan Cermak)
Fixed bug #46365: tcp_accept_null() should call tcp_abort()
Fixed compiling with LWIP_TCP==0
fixed bug #46471: lwip_accept() leaks socket descriptors if new netconn
was already closed because of peer behavior
Check TCP_SNDLOWAT for too high value (near u16_t overflow) - fixes bug
#46948

unsigned expression"
cleaned up includes a bit after IPv6 changes
Added macro to get the ip address type
sntp: fixed constness for SNTP_SERVER_DNS==1
fixed wrong commit: compatibility-define tcp_accepted() was accidentally
commented-out
... and another compiler error: tcp_nagle_enable() must stay at
tcpflags_t, not using u16_t
lwip_accept: fixed returning EOPNOTSUPP instead of -1 (EOPNOTSUPP is set
as socket error)
minor whitespace change only
removed unused return values of tcp_listen_input & tcp_timewait_input;
fixed unused variable warning
httpd improvements: added persistent connections, improved asynchronous
read mode, compile-time deflate compression, new CGI mode, SSI handler can be
called with tag string (instead of tag index)
fixed bug #47743 (Closing listening tcp pcb is not posible without assert)
fixed bug #47601 (wrong NS request at DAD)

Allow IPv6 addresses with arbitrary prefix.
Allow routing IPv6 packets to neighbours with manually-configured
non-link-local addresses.
Process IPv6 packets arriving from non-Ethernet links.
Don't forward IPv6 packets that are larger than outgoing MTU, send ICMPv6

etharp_output_sent no longer exists
remove global ctime.Each entry's ctime is now absolute.This avoids
wrapping and also solves naming clash reported on the list

unreachable when the port is unavailable
Fix locking for disconnect operation (use post and fetch on the
connection's mbox in the two threads like other operations).Make netconn_peer
take a pointer to addr instead of pointer to pointer to addr.Addr is a 4 byte
struct an IP address so use structure assignment not just pointer assignment
when saving the peer.This way the address is really saved :fixes bug #1897
recvfrom accesses freed netbuf.If it's reused in the small window by
another thread recvfrom returns bad from info.Patch #1041 by Florian Zschocke

warnings.
byte-order handling functions are in inet.c now and the uperrcase
counterparts are gone. opt.h has all the

user file lwippools.h. (Remove MEMP_POOL_SIZE/NUM flags, add new
MEMP_USE_CUSTOM_POOLS option)
*** empty log message ***
Task #7143: Clean up opt.h. Made all the comment formats the same (uses
Doxygen style), a couple minor reorderings. Changed a few of the default stats
variables to depend on whether the modules were even used (i.e. #define
TCP_STATS (LWIP_TCP) ). PPP options could still use some cleaning.
Task #7136: Fix bug of wrong file name for centralized mempool settings.
Move deprecated options from opt.h to init.c
Put back in SO_REUSE
DHCP_DOES_ARP_CHECK is set to 1 by default -- the compile-time checks
fail if DHCP is off... So this patch sets the default to be 1 only if both DHCP
and ARP are set.

email notification.
Fixed NULL pointer bug (#1493). Fix for memory leak bug (#1601),
etharp_output_sent(). Added etharp_query for DHCP.
To prevent compiler warnings, added UL to some bit mask constants.
find_arp_entry() returned 0 instead of ARP_TABLE_SIZE if full pending

comments and JavaDoc documentation.
Surrounded all #include's for packed structs with #ifdef's.
Added pbuf_ref_chain() which increases ref count of all pbufs in a chain.
memp_alloc() now zeroes allocated memory (for robustness). Callers must

missed in last commit.
Note about ethernetif.c not up-to-date with etharp.c API. Fixed typo.
Fixes all issues that showed up after the first commit.

Added commented about the signedness of pbuf_header() argument.
Added comments. Code cleanup. Clearer debugging in udp_input().
Changed some comments into JavaDoc format.

instead of using one per netconn and per select call
fixed indentation
- fixed bug #43797 set/getsockopt: SO_SNDTIMEO/SO_RCVTIMEO take int as
option but should take timeval (LWIP_SO_SNDRCVTIMEO_STANDARD==0 can be used to
revert to the old 'winsock' style behaviour);
fixed bug #40788 "lwip_setsockopt_internal() crashes" by rewriting
set/getsockopt functions to combine checks with the actual code and add more
NULL checks; this also fixes that CORE_LOCKING used message passing for
set/getsockopt.
tcp_close_shutdown: remove invalid comment on linger: we cannot support
linger for the raw API since linger implies blocking
allow enabling socket API without (public) netconn API - netconn API is
still used by sockets, but keeping it private (static) should allow better
compiler optimizations
patch #8479 Fixed a visibility scope that caused a compile error in some
configurations (by Constantine <nongnusucks>)
fixed bug #43361 select() crashes with stale FDs
netconn_delete(): check for errors returned by lwip_netconn_do_delconn()
and don't call netconn_free() on error
Fixed bug #38315 tcp_eff_send_mss_impl() always subtract the difference
in IPv6 header size
fixed that SHUT_RD followed by SHUT_WR was different to SHUT_RDWR, fixed
return value of lwip_netconn_do_close on unconnected netconns
changed comment in struct linger
netconn/socket api: fixed bug #44225 "closing TCP socket should time out
eventually", implemented task #6930 "Implement SO_LINGER": closing TCP sockets
times out after 20 seconds or after the configured SND_TIMEOUT or depending on
the linger settings; fixed that netconn_close/netconn_delete still used message
passing for LWIP_TCPIP_CORE_LOCKING==1
Added comment that sys_thread_new must not fail (ports have to assert
this!)
started to implement fullduplex sockets/netconns (note that this is
highly unstable yet!)
patch #8423 "arch/perf.h" should be made an optional item
fixed bug #43094 "The function tcpip_input() forget to handle IPv6"

enterprise
added support for write-access community and dedicated community for
sending traps
patch #8361 "Add support for NTP option in DHCP" (slighly modified)
sockets.c: removed LWIP_TCPIP_CORE_LOCKING hack in lwip_sendto(): since
all functions are static when LWIP_NETCONN==0, the speedup gained by this hack
should now be minimal and not worth the duplicate code.
fixed bug #38853 "connect() use a wrong errno": return
ERR_ALREADY/EALRADY during connect, ERR_ISCONN/EISCONN when already connected
Fixed select not reporting received FIN as 'readable' in certain rare
cases (bug #43779: select(), close(), and TCP retransmission error)
"Not connected" shouldn't be fatal (as opposed to "closed")
tcp_alloc() prefers killing CLOSING/LAST_ACK over active connections (see
bug #39565) (tcp_kill_prio(): back to old implementation)
fixed bug #37958 "netconn API doesn't handle correctly connections
half-closed by peer"
PPP: fixed 2 warnings found by MSVC
Continued chrysn's work: changed nearly all functions taking

get/setsockopt only)
patch by Jens Nielsen: fixed bug #38803 (Source address in broadcast ping

default netif for multicast routing
fixed bug #38165 (socket with mulicast): ensure igmp membership are
dropped when socket (not netconn!) is closed.

work on task #12357 (Ensure that malicious packets don't assert-fail):
don't let too short IP packets assert-fail; fix that IPv6 input did not obey
VLAN header offset

init.c: raise an error if LWIP_PPP_API==1 but PPP_SUPPORT==0
fixed bug #43784 (a host should send at least one Router Solicitation)
fixed bug #37068 (netif up/down handling is unclear): correclty separated
administrative status of a netif (up/down) from 'valid address' status
ATTENTION: netif_set_up() now always has to be called, even when dhcp/autoip is
used!
tcp/udp_netif_ipv4_addr_changed(): don't change specific-address of local
tcp_listen/udp_pcb to ANY on address change
Fixed comment for NETIF_FLAG_UP after fixing bug #37068

fixed bug #34617: Stable etharp entries that are about to expire are now
refreshed using unicast to prevent unnecessary broadcast.
fixed bug #36017 ARP might not support duplicate addresses on multiple
netifs (tried to correctly handle duplicate AutoIP addresses on multiple
netifs, but only if explicitly enabled via ETHARP_TABLE_MATCH_NETIF==1)
etharp: reduce ARP aging timeout from 20 minutes to 5 minutes, since this
is a time obviously used in some switches as MAC learning table timeout. Having
our ARP timeout higher than this can lead to sending unicast packets to
multiple network segments.
Added input & route hooks for IPv6 to stay in line with IPv4
loopif is not required for loopback traffic any more but passed through
any netif (ENABLE_LOOPBACK has to be enabled) (task #13515)
used ip6_addr_t instead of struct ip6_addr, fix const'ness in ip6_route
parameters
task #12722 (improve IPv4/v6 address handling): renamed ip_addr_t to
ip4_addr_t, renamed ipX_addr_t to ip_addr_t and added IP version;

leaving an IPv6-only stack (SNMP is still missing)
Fixed ntoa/aton/ntop/pton definitions after making IPv4 optional
Worked on IPv6-only stack:
Worked on IPv6-only stack: netdb should work

track bugfixed in CHANGELOG
Fixed more compiler warnings for unit tests
LWIP_COMPAT_SOCKETS==2: special setting to help code parsers/code
completion to show argument names/types for posix socket functions
Tried to improve pbuf_type, LWIP_SUPPORT_CUSTOM_PBUF and
PBUF_FLAG_IS_CUSTOM documentation
allow multicast socket options IP_MULTICAST_TTL, IP_MULTICAST_IF and
IP_MULTICAST_LOOP to be used without IGMP
Enable LWIP_HAVE_LOOPIF by default when LWIP_NETIF_LOOPBACK==1 to not
make loopback traffic depend on the only netif's link state

TCP_SLOW_INTERVAL
dns: fixed assertion when dns server address is set to ANY (patch #8692)
patch by Chrysn: patch #8704 fix sys_timeouts_sleeptime function
fixed bug #45120: Broadcast & multiple interfaces handling
Fixed icmp.c after 1.4.0-based patch #45120
- prework for fixing bug #45029: access IPv4 configuration of struct
netif via new API (netif_ip4_addr()/netif_ip4_netmask()/netif_ip4_gw()) instead
of accessing the struct member directly. This way, we can change the struct
member types from ip4_addr_t to ip_addr_t;
Change IP6_ADDR/IP_ADDR6 to initialize a full IPv6 address (e.g. use with
PP_HTONL) - renamed old IP6_ADDR() to IP6_ADDR_PART()
more cleanup prework to fix bug #45029
fixed bug #45827: recvfrom: TCP window is updated with MSG_PEEK
fix comment indentation
LWIP_LOOPIF_MCAST -> LWIP_LOOPIF_MULTICAST
IPV6_REASS: fix ip6_reass_remove_oldest_datagram() when the first
fragment to enqueue has more pbufs than IP_REASS_MAX_PBUFS
fixed bug bug #41009: IPv6 reassembly broken on 64-bit platforms: define
IPV6_FRAG_COPYHEADER==1 on these platforms to copy the IPv6 header instead of
referencing it, which gives more room for struct ip6_reass_helper
Remove empty init functions where not required for backwards compatibility
Fixed UPGRADING regarding 1.4.0
Add another sanity check for bug #41009
fixed bug #44023: TCP ssthresh value is unclear: ssthresh is set to the
full send window for active open, too, and is updated once after SYN to ensure
the correct send window is used
support IPv4 source based routing: define LWIP_HOOK_IP4_ROUTE_SRC to
point to a routing function
task #12178: hardware checksum capabilities can be configured per netif
(use NETIF_SET_CHECKSUM_CTRL() in your netif's init function)
fixed missing #endif
lwip_getaddrinfo: check max name length
fixed unused variable warning
Changed dns_gethostbyname_addrtype() to always be a function, fixed code
for C PP :-(
fixed compiling DNS code again
Fixed passing ip_input() to netif_add() for single-IP-version NO_SYS
configurations
fixed constness for DNS_LOCAL_HOSTLIST_IS_DYNAMIC
fixed some printf formatters (mainly for window scaling code)
fixed compiling lwip_sendmsg for LWIP_NETIF_TX_SINGLE_PBUF &&
LWIP_CHECKSUM_ON_COPY
fixed const warning for !IPV6_FRAG_COPYHEADER
fixed compiler warnings reported by mingw-64
fixed compiling for various config combinations
PPP: more const fixes
Added ip_addr_set_zero_ip4() to explicitly set the type to IPv4 for
dual-stack
fixed compiling udp.c for IPv6-only
Fixed IP_ADDR6 macro for IPv6 only
task #13729: Convert netif addresses (IPv4 & IPv6) to ip_addr_t (so they
can be used without conversion/temporary storage)
fixed coding style: use more ()
PPP: include "ppp_settings.h" if PPP_INCLUDE_SETTINGS_HEADER is defined
to be able to silence some warnings in PPP code only (at least msvc needs this
since PPP produces more warnings than the rest)
ip4_route: fixed checking twice for a valid default_netif, fixed checking
loopback traffic before checking for a valid default netif
Make LWIP_DNS_SECURE and its possible values known in opt.h, remove
default initialization of DNS server
snmp: hopefully fixed all alignment warnings introduced today.
unfortunately, gcc does not warn about them when compiling for x86
snmp mib2: more const
minor/coding style: removed spaces before line ending
minor/coding style: removed spaces before line ending (from file header)
minor: coding style
first 'app': added SNTP client from contrib (unmodified from
196cbae376dfd484b4833503dd43057b4c3462fa, 28.08.2015)
added sntp_opts.h (all options for the sntp app), added FILES to describe
the include folder
fixed header include guard, fixed FILES
Added lwiperf, a simple ipv4/tcp iperf peer
lwiperf: fixed const-cast warning
removed spaces at line ending, fixed include guard
added netbios name server from contrib (-> netbiosns)
netbios -> netbiosns, added netbiosns_opts.h, added netbiosns_set_name()
and netbiosns_stop()
Make LWIP_RAW==0 the default, raw IP sockets/pcbs should not be too
common to justify the increased codesize for default setups
Fixed compiling api with LWIP_NETCONN_SEM_PER_THREAD==1 &&
LWIP_MPU_COMPATIBLE==1
moved dhcp.c to src/core/ipv4/ since it is IPv4 only
started to move "private" header files containing implementation details
to "lwip/priv/" include directory to seperate the API from the implementation.
re-added tcpip.h (removed because the better part of the file moved to
"priv/tcpip_priv.h", which was more worth conserving the git history - how do
you duplicate a file keeping its history in both copies??)
pppapi/ppos: include tcpip_priv.h, not tcpip.h
minor: fixed typo: even_callback -> event_callback
fixed bug #46321: Synchronization bug around lwip_select() and
tcpip_thread() with thread-local semaphores
Fixed bug #47154 lwip_netconn_do_writemore doesn't clear
conn->write_offset on fatal/routing error.
minor/coding style: lowpan6_opts.h: tabs->spaces, trim trailing spaces
minor: udp_input/local_match: coding style, added comments
Fixed bug #46524: "Device as dhcp server does not work after upgrade to
lwip-1.4.1"
dual-stack fix: moved common definitions/code for ethernet used by etharp
and ethip6 to new files ethernet.h/.c
added ethernet.c to Filelists.mk
Tried to fix bug #47270 by accepting all ipv4 multicast packets (at IP
level) when LWIP_IGMP is disabled
fixed bug #46093: Move IP6_ROUTE() hook to after LL processing
bug #46094: moved IPv4 routing hook functions down so that they implement
actual routing (source-based IPv4 routing is not affected by this change)
fixed icmp_send_response with LWIP_HOOK_IP4_ROUTE_SRC enabled
ERR_IF is not necessarily a fatal error (fixes bug #46338: UDP netconns
block after fatal error)
fixed bug #45353: IPv6 router / neighbor relationship is not always
consistent - patch by Stian Sebastian Skjelstad
fixed typo in one of the last commits
dns_gethostbyname: return error code if no valid server is set instead of
calling the 'found' callback in this case (fixes bug #46887)
fixed ERR_IS_FATAL() after changing ERR_IF to non-fatal
Work on bug #44595: remove check for recvmbox != NULL from netconn_recv()
to let it return ERR_CLSD for half-closed TCP connections
fixed bug #46384 Segment size calculation bug with MSS != TCP_MSS
ethernetif.c: implement SNMP counters, simplify input function: no need
to check ethType, ethernet_input() already does this
LWIP_TCPIP_CORE_LOCKING_INPUT is not experimental any more, as well
reset rto timer on fast retransmission (see task #13757, patch by Joel
Cunningham)
tcp_output_segment: don't count retransmitted segments in mib2.tcpoutsegs
by detecting p->payload != tcphdr pointer; don't try to retransmit segments
where p->ref != 1 (as it is invalid to mess up p->len/p->payload when we don't
have exclusive access to the pbuf)
Optimize tcp_output runtime by not calling ip_route() for every segment
sent
fixed compiling netconn_write_partly with LWIP_SO_SNDTIMEO==1 after
recent api implementation changes (bug #47436, patch by William Hayes)
fixed bug #47448 (netconn/socket leak if RST is received during close)
define tcp_backlog_set() as dummy-define when backlog feature is disable
tcp_alloc(): remove explicit =0 already done by memset(0)
ignore dns response parsing errors, only abort resolving for correct
responses or error responses from correct server (bug #47459)
tcp: changed accept handling to be done internally: the application does
not have to call tcp_accepted() any more. Instead, when delaying accept (e.g.
sockets do), call tcp_backlog_delayed()/tcp_backlog_accepted() (fixes bug
#46696)
fixed bug #38203: DHCP options are not recorded in all DHCP ack messages
(patch by Florent Matignon)
call accept-callback with ERR_MEM when allocating a pcb fails on passive
open to inform the application about this error; ATTENTION: applications have
to handle NULL pcb in accept callback!
Fixed possible problems with tcp_backlog_delayed/tcp_backlog_accepted
make autoip_supplied_address() take a const pointer, too
fixed bug #47625 (Error in compilation of C++ source using netifapi
macros) by changing NULL define for __cplusplus
fixed bug# 43739 (Accept not reporting errors about aborted connections):
netconn_accept() returns ERR_ABRT (sockets: ECONNABORTED) for aborted
connections, ERR_CLSD (sockets: EINVAL) if the listening netconn is closed,
which better seems to follow the standard
patch #8358: allow more combinations of listening PCB for IPv6
prepare for overriding current timeout implementation: all stack-internal
caclic timers are avaliable in the lwip_cyclic_timers array
Set LWIP_VERSION_RC to RC1
softins (14):
Removed spurious semicolon and added missing end-of-comment.
Changed recv_raw() from int to u8_t, to match prototype of raw_recv() in
raw.h
Added trivial (int) cast to keep compiler happier.
Changed debug statements to use the tidier ip4_addrN() macros.
Updated low_level_output() to match prototype for netif->linkoutput
Made data types consistent in inet_ntoa().
Small corrections to some debugging statements, to pacify compiler.
Added a couple of casts to quiet the compiler.
Corrected IPH_TOS() macro: returns a byte, so doesn't need htons().
Stop compiler complaining of empty if statement when LWIP_DEBUGF() empty.
Stop compiler complaining of empty if statement when LWIP_DEBUGF() empty.
Add (int) cast in LWIP_DEBUGF() to avoid compiler warnings about
comparison.
Make sure the first pbuf queued on an ARP entry is properly ref counted.
Added my July and August updates.
stoklund (6):
Reuse XIDs for DHCP retransmissions
Implement exponential backoff in dhcp.c
Don't use an AutoIP-configured address on a new network until the address
has been configured.
The DHCP client should enter the REBOOTING state when connecting to a
Add C++ guards to autoip.h header.
Add patch #6725 to CHANGELOG
tabascoeye (1):
icmp: fix checksum on replies of echo request with ID 0, sequence 0 and
either no data or any amount of 0x00 Bytes as data (closes: #45322)
uid67528 (1):
Merged from DEVEL. etharp prepared for queueing feature. DHCP fix.
