2021-07-09blockdev: fix drive-backup transaction endless drained sectionVladimir Sementsov-Ogievskiy
drive_backup_prepare() does bdrv_drained_begin() in hope that bdrv_drained_end() will be called in drive_backup_clean(). Still we need to set state->bs for this to work. That's done too late: a lot of failure paths in drive_backup_prepare() miss setting state->bs. Fix that.

2021-07-09vhost-user: Fix backends without multiqueue supportKevin Wolf
dev->max_queues was never initialised for backends that don't support VHOST_USER_PROTOCOL_F_MQ, so it would use 0 as the maximum number of queues to check against and consequently fail for any such backend. Set it to 1 if the backend doesn't have multiqueue support.

2021-07-09export/fuse: Add allow-other optionMax Reitz
Without the allow_other mount option, no user (not even root) but the one who started qemu/the storage daemon can access the export. Allow users to configure the export such that such accesses are possible. While allow_other is probably what users want, we cannot make it an unconditional default, because passing it is only possible (for non-root users) if the global fuse.conf configuration file allows it. Thus, the default is an 'auto' mode, in which we first try with allow_other, and then fall back to without. FuseExport.allow_other reports whether allow_other was actually used as a mount option or not. Currently, this information is not used, but a future patch will let this field decide whether e.g. an export's UID and GID can be changed through chmod. One notable thing about 'auto' mode is that libfuse may print error messages directly to stderr, and so may fusermount (which it executes). Our export code cannot really filter or hide them. Therefore, if 'auto' fails its first attempt and has to fall back, fusermount will print an error message that mounting with allow_other failed. This behavior necessitates a change to iotest 308, namely we need to filter out this error message (because if the first attempt at mounting with allow_other succeeds, there will be no such message). Furthermore, common.rc's _make_test_img should use allow-other=off for FUSE exports, because iotests generally do not need to access images from other users, so allow-other=on or allow-other=auto have no advantage. OTOH, allow-other=on will not work on systems where user_allow_other is disabled, and with allow-other=auto, we get said error message that we would need to filter out again. Just disabling allow-other is simplest. Signed-off-by: Max Reitz <mreitz@redhat.com> Message-Id: <20210625142317.271673-3-mreitz@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2021-07-09export/fuse: Pass default_permissions for mountMax Reitz
We do not do any permission checks in fuse_open(), so let the kernel do them. We already let fuse_getattr() report the proper UNIX permissions, so this should work the way we want. This causes a change in 308's reference output, because now opening a non-writable export with O_RDWR fails already, instead of only actually attempting to write to it. (That is an improvement.)

2021-07-09block/rbd: add write zeroes supportPeter Lieven
This patch wittingly sets BDRV_REQ_NO_FALLBACK and silently ignores BDRV_REQ_MAY_UNMAP for older librbd versions. The rationale for this is as follows (citing Ilya Dryomov current RBD maintainer): ---8<--- a) remove the BDRV_REQ_MAY_UNMAP check in qemu_rbd_co_pwrite_zeroes() and as a consequence always unmap if librbd is too old It's not clear what qemu's expectation is but in general Write Zeroes is allowed to unmap. The only guarantee is that subsequent reads return zeroes, everything else is a hint. This is how it is specified in the kernel and in the NVMe spec. In particular, block/nvme.c implements it as follows: if (flags & BDRV_REQ_MAY_UNMAP) { cdw12 |= (1 << 25); } This sets the Deallocate bit. But if it's not set, the device may still deallocate: """ If the Deallocate bit (CDW12.DEAC) is set to '1' in a Write Zeroes command, and the namespace supports clearing all bytes to 0h in the values read (e.g., bits 2:0 in the DLFEAT field are set to 001b) from a deallocated logical block and its metadata (excluding protection information), then for each specified logical block, the controller: - should deallocate that logical block; ... If the Deallocate bit is cleared to '0' in a Write Zeroes command, and the namespace supports clearing all bytes to 0h in the values read (e.g., bits 2:0 in the DLFEAT field are set to 001b) from a deallocated logical block and its metadata (excluding protection information), then, for each specified logical block, the controller: - may deallocate that logical block; """ https://nvmexpress.org/wp-content/uploads/NVM-Express-NVM-Command-Set-Specification-2021.06.02-Ratified-1.pdf b) set BDRV_REQ_NO_FALLBACK in supported_zero_flags Again, it's not clear what qemu expects here, but without it we end up in a ridiculous situation where specifying the "don't allow slow fallback" switch immediately fails all efficient zeroing requests on a device where Write Zeroes is always efficient: $ qemu-io -c 'help write' | grep -- '-[zun]' -n, -- with -z, don't allow slow fallback -u, -- with -z, allow unmapping -z, -- write zeroes using blk_co_pwrite_zeroes $ qemu-io -f rbd -c 'write -z -u -n 0 1M' rbd:foo/bar write failed: Operation not supported --->8--- Signed-off-by: Peter Lieven <pl@kamp.de> Reviewed-by: Ilya Dryomov <idryomov@gmail.com> Message-Id: <20210702172356.11574-6-idryomov@gmail.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2021-07-06vl: switch -M parsing to keyvalPaolo Bonzini
Switch from QemuOpts to keyval. This enables the introduction of non-scalar machine properties, and JSON syntax in the future. For JSON syntax to be supported right now, we would have to consider what would happen if string-based dictionaries (produced by -M key=val) were to be merged with strongly-typed dictionaries (produced by -M {'key': 123}). The simplest way out is to never enter the situation, and only allow one -M option when JSON syntax is in use. However, we want options such as -smp to become syntactic sugar for -M, and this is a problem; as soon as -smp becomes a shortcut for -M, QEMU would forbid using -M '{....}' together with -smp. Therefore, allowing JSON syntax right now for -M would be a forward-compatibility nightmare and it would be impossible anyway to introduce -M incrementally in tools. Instead, support for JSON syntax is delayed until after the main options are converted to QOM compound properties. These include -boot, -acpitable, -smbios, -m, -semihosting-config, -rtc and -fw_cfg. Once JSON syntax is introduced, these options will _also_ be forbidden together with -M '{...}'. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
