This adds v6 of the NFS protocol driver + qemu-iotest adjustments. 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] Peter Lieven (5): 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: blacklist test 020 for NFS protocol MAINTAINERS | 5 + block/Makefile.objs | 1 + block/nfs.c | 440 ++++++++++++++++++++++++++++++++++++++++++ configure | 26 +++ qapi-schema.json | 1 + tests/qemu-iotests/013 | 2 +- tests/qemu-iotests/014 | 2 +- tests/qemu-iotests/016 | 2 +- tests/qemu-iotests/018 | 2 +- tests/qemu-iotests/019 | 2 +- tests/qemu-iotests/020 | 5 + tests/qemu-iotests/023 | 2 +- tests/qemu-iotests/024 | 2 +- tests/qemu-iotests/025 | 2 +- tests/qemu-iotests/026 | 2 +- tests/qemu-iotests/028 | 2 +- tests/qemu-iotests/031 | 2 +- tests/qemu-iotests/034 | 2 +- tests/qemu-iotests/036 | 2 +- tests/qemu-iotests/037 | 2 +- tests/qemu-iotests/038 | 2 +- tests/qemu-iotests/039 | 2 +- tests/qemu-iotests/043 | 2 +- tests/qemu-iotests/046 | 2 +- tests/qemu-iotests/052 | 2 +- tests/qemu-iotests/054 | 2 +- tests/qemu-iotests/059 | 2 +- tests/qemu-iotests/060 | 2 +- tests/qemu-iotests/061 | 2 +- tests/qemu-iotests/063 | 2 +- tests/qemu-iotests/069 | 2 +- tests/qemu-iotests/common | 22 ++- tests/qemu-iotests/common.rc | 3 + 33 files changed, 525 insertions(+), 28 deletions(-) create mode 100644 block/nfs.c -- 1.7.9.5
