civodul pushed a commit to branch core-updates
in repository guix.
commit e37595d9617658e3098b1d1b3f9f5d9aad4daf53
Author: Ludovic Courtès <address@hidden>
Date: Wed Apr 6 22:20:49 2016 +0200
gnu: glibc: Update to 2.23.
* gnu/packages/base.scm (glibc): Update to 2.23. Remove
"glibc-locale-incompatibility.patch" and "glibc-CVE-2015-7547.patch",
now unneeded.
[arguments]: Add "libc_cv_ssp_strong=no" to #:configure-flags. Remove
now unneeded patching of 'configure'.
* gnu/packages/patches/glibc-CVE-2015-7547.patch: Remove.
* gnu/packages/patches/glibc-locale-incompatibility.patch: Remove.
* gnu-system.am (dist_patch_DATA): Adjust accordingly.

-+ TRYAGAIN, NOTFOUND and UNAVAIL, since they are the only returns
-+ that apply (though RETURN and MERGE exist). We make a distinction
-+ between TRYAGAIN (recoverable) and TRYAGAIN' (not-recoverable).
-+ A recoverable TRYAGAIN is almost always due to buffer size issues
-+ and returns ERANGE in errno and the caller is expected to retry
-+ with a larger buffer.
-+
-+ Lastly, you may be tempted to make significant changes to the
-+ conditions in this code to bring about symmetry between responses.
-+ Please don't change anything without due consideration for
-+ expected application behaviour. Some of the synthesized responses
-+ aren't very well thought out and sometimes appear to imply that
-+ IPv4 responses are always answer 1, and IPv6 responses are always
-+ answer 2, but that's not true (see the implemetnation of send_dg
-+ and send_vc to see response can arrive in any order, particlarly
-+ for UDP). However, we expect it holds roughly enough of the time
-+ that this code works, but certainly needs to be fixed to make this
-+ a more robust implementation.

-+ ----------------------------------------------
-+
-+ [1] If the first response is a success we return success.
-+ This ignores the state of the second answer and in fact
-+ incorrectly sets errno and h_errno to that of the second
-+ answer. However because the response is a success we ignore
-+ *errnop and *h_errnop (though that means you touched errno on
-+ success). We are being conservative here and returning the
-+ likely IPv4 response in the first answer as a success.
-+
-+ [2] If the first response is a recoverable TRYAGAIN we return
-+ that instead of looking at the second response. The
-+ expectation here is that we have failed to get an IPv4 response
-+ and should retry both queries.
-+
-+ [3] If the first response was not a SUCCESS and the second
-+ response is not NOTFOUND (had a SUCCESS, need to TRYAGAIN,
-+ or failed entirely e.g. TRYAGAIN' and UNAVAIL) then use the
-+ result from the second response, otherwise the first responses
-+ status is used. Again we have some odd side-effects when the
-+ second response is NOTFOUND because we overwrite *errnop and
-+ *h_errnop that means that a first answer of NOTFOUND might see
-+ its *errnop and *h_errnop values altered. Whether it matters
-+ in practice that a first response NOTFOUND has the wrong
-+ *errnop and *h_errnop is undecided.
-+
-+ [4] If the first response is UNAVAIL we return that instead of
-+ looking at the second response. The expectation here is that
-+ it will have failed similarly e.g. configuration failure.
-+
-+ [5] Testing this code is complicated by the fact that truncated
-+ second response buffers might be returned as SUCCESS if the
-+ first answer is a SUCCESS. To fix this we add symmetry to
-+ TRYAGAIN with the second response. If the second response
-+ is a recoverable error we now return TRYAGIN even if the first
-+ response was SUCCESS. */

-+/* The send_vc function is responsible for sending a DNS query over TCP
-+ to the nameserver numbered NS from the res_state STATP i.e.
-+ EXT(statp).nssocks[ns]. The function supports sending both IPv4 and
-+ IPv6 queries at the same serially on the same socket.
-+
-+ Please note that for TCP there is no way to disable sending both
-+ queries, unlike UDP, which honours RES_SNGLKUP and RES_SNGLKUPREOP
-+ and sends the queries serially and waits for the result after each
-+ sent query. This implemetnation should be corrected to honour these
-+ options.
-+
-+ Please also note that for TCP we send both queries over the same
-+ socket one after another. This technically violates best practice
-+ since the server is allowed to read the first query, respond, and
-+ then close the socket (to service another client). If the server
-+ does this, then the remaining second query in the socket data buffer
-+ will cause the server to send the client an RST which will arrive
-+ asynchronously and the client's OS will likely tear down the socket
-+ receive buffer resulting in a potentially short read and lost
-+ response data. This will force the client to retry the query again,
-+ and this process may repeat until all servers and connection resets
-+ are exhausted and then the query will fail. It's not known if this
-+ happens with any frequency in real DNS server implementations. This
-+ implementation should be corrected to use two sockets by default for
-+ parallel queries.
-+
-+ The query stored in BUF of BUFLEN length is sent first followed by
-+ the query stored in BUF2 of BUFLEN2 length. Queries are sent
-+ serially on the same socket.
-+
-+ Answers to the query are stored firstly in *ANSP up to a max of
-+ *ANSSIZP bytes. If more than *ANSSIZP bytes are needed and ANSCP
-+ is non-NULL (to indicate that modifying the answer buffer is allowed)
-+ then malloc is used to allocate a new response buffer and ANSCP and
-+ ANSP will both point to the new buffer. If more than *ANSSIZP bytes
-+ are needed but ANSCP is NULL, then as much of the response as
-+ possible is read into the buffer, but the results will be truncated.
-+ When truncation happens because of a small answer buffer the DNS
-+ packets header feild TC will bet set to 1, indicating a truncated
-+ message and the rest of the socket data will be read and discarded.
-+
-+ Answers to the query are stored secondly in *ANSP2 up to a max of
-+ *ANSSIZP2 bytes, with the actual response length stored in
-+ *RESPLEN2. If more than *ANSSIZP bytes are needed and ANSP2
-+ is non-NULL (required for a second query) then malloc is used to
-+ allocate a new response buffer, *ANSSIZP2 is set to the new buffer
-+ size and *ANSP2_MALLOCED is set to 1.
-+
-+ The ANSP2_MALLOCED argument will eventually be removed as the
-+ change in buffer pointer can be used to detect the buffer has
-+ changed and that the caller should use free on the new buffer.
-+
-+ Note that the answers may arrive in any order from the server and
-+ therefore the first and second answer buffers may not correspond to
-+ the first and second queries.
-+
-+ It is not supported to call this function with a non-NULL ANSP2
-+ but a NULL ANSCP. Put another way, you can call send_vc with a
-+ single unmodifiable buffer or two modifiable buffers, but no other
-+ combination is supported.
-+
-+ It is the caller's responsibility to free the malloc allocated
-+ buffers by detecting that the pointers have changed from their
-+ original values i.e. *ANSCP or *ANSP2 has changed.
-+
-+ If errors are encountered then *TERRNO is set to an appropriate
-+ errno value and a zero result is returned for a recoverable error,
-+ and a less-than zero result is returned for a non-recoverable error.
-+
-+ If no errors are encountered then *TERRNO is left unmodified and
-+ a the length of the first response in bytes is returned. */
