[Qemu-devel] [PATCHv6 0/6] block: add native support for NFS


From: Peter Lieven
Subject: [Qemu-devel] [PATCHv6 0/6] block: add native support for NFS
Date: Mon, 13 Jan 2014 11:21:52 +0100

This adds v6 of the NFS protocol driver + qemu-iotest adjustments.

v5->v6:
 - use internal qemu function to parse the NFS url [Kevin]
 - zero pad short reads [Kevin, Paolo]
 - added qemu-iotests patches for basic nfs protocol support

v4->v5:
 - disussed with Ronnie and decided to move URL + Paramter parsing to LibNFS.
   This allows for URL parameter processing directly in LibNFS without altering
   the qemu NFS block driver. This bumps the version requirement for LibNFS
   to 1.9.0 though.
 - added a pointer to the LibNFS readme where additional information about
   ROOT privilidge requirements can be found as this raised a few concerns.
 - removed a trailing dot in an error statement [Fam].

v3->v4:
 - finally added full implementation of bdrv_get_allocated_file_size [Stefan]
 - removed trailing \n from error statements [Stefan]

v2->v3:
 - rebased the stefanha/block
 - use pkg_config to check for libnfs (ignoring cflags which are broken in 
1.8.0) [Stefan]
 - fixed NFSClient declaration [Stefan]
 - renamed Task variables to task [Stefan]
 - renamed NFSTask to NFSRPC [Ronnie]
 - do not update bs->total_sectors in nfs_co_writev [Stefan]
 - return -ENOMEM on all async call failures [Stefan,Ronnie]
 - fully implement ftruncate
 - use util/uri.c for URL parsing [Stefan]
 - reworked nfs_file_open_common to nfs_client_open which works on NFSClient 
[Stefan]
 - added a comment ot the connect message that libnfs support NFSv3 only at the 
moment.
 - DID NOT add full implementation of bdrv_get_allocated_file_size because
   we are not in a coroutine context and I cannot do an async call here.
   I could do a sync call if there would be a guarantee that no requests
   are in flight. [Stefan]

v1->v2:
 - fixed block/Makefile.objs [Ronnie]
 - do not always register a read handler [Ronnie]
 - add support for reading beyond EOF [Fam]
 - fixed struct and paramter naming [Fam]
 - fixed overlong lines and whitespace errors [Fam]
 - return return status from libnfs whereever possible [Fam]
 - added comment why we set allocated_file_size to -ENOTSUP after write [Fam]
 - avoid segfault when parsing filname [Fam]
 - remove unused close_bh from NFSClient [Fam]
 - avoid dividing and mutliplying total_size by BDRV_SECTOR_SIZE in 
nfs_file_create [Fam] 

Peter Lieven (6):
  block: add native support for NFS
  qemu-iotests: change _supported_proto to file for various tests
  qemu-iotests: enable support for NFS protocol
  qemu-iotests: enable test 016 and 025 to work with NFS protocol
  qemu-iotests: fix expected output of test 067
  qemu-iotests: blacklist test 020 for NFS protocol
