[Qemu-devel] [PATCHv8 0/5] block: add native support for NFS |
Date: |

This adds v6 of the NFS protocol driver + qemu-iotest adjustments.
v7->v8:
- bump libnfs requirement to 1.9.2
- renamed NFSRPC->status to NFSRPC->ret [Benoit]
- avoid double invocation of nfs_client_close in nfs_file_create [Benoit]
- fixed error propagation in nfs_file_open [Benoit]
v6->v7:
- removed unsused and partially non-existing libnfs header file includes
[Stefan]
- adjusted usage of qemu_opts_create_nofail [Stefan]
- removed patch to fix output of qemu-iotest 067
- only blacklist qemu-iotest 020 for NFS do not change proto from generic to
file [Fam]
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]
