- Fix nbd_export_close_all() crash
- Fix race in iotests case 030
- qemu-img resize: Require --shrink for shrinking all image formats
- crypto: use a stronger private key for tests
- Remove VXHS block device
- MAINTAINERS: vvfat: set status to odd fixes
----------------------------------------------------------------

However, for compatibility reasons, it was not enforced for raw images yet, but only a deprecation warning was printed. This warning has existed for long enough that we can now finally require --shrink for raw images, too, and error out if it's not given. Documentation already describes the state as it is after this patch. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Message-Id: <20200710121717.28339-1-kwolf@redhat.com> Reviewed-by: Daniel P.

The call-stack looks like this: nbd_export_close_all() -> nbd_export_close -> call client_close() for each client. client_close() doesn't guarantee that client is closed: nbd_trip() keeps reference to it. So, nbd_export_close_all() just reduce reference counter on export and removes it from the list, but doesn't guarantee that nbd_trip() finished neither export actually removed. Let's wait for all exports actually removed. Without this fix, the following crash is possible: - export bitmap through internal Qemu NBD server - connect a client - shutdown Qemu On shutdown nbd_export_close_all is called, but it actually don't wait for nbd_trip() to finish and to release its references. So, export is not release, and exported bitmap remains busy, and on try to remove the bitmap (which is part of bdrv_close()) the assertion fails: bdrv_release_dirty_bitmap_locked: Assertion `!bdrv_dirty_bitmap_busy(bitmap)' failed Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Reviewed-by: Eric Blake <eblake@redhat.com> Message-Id: <20200714162234.13113-2-vsementsov@virtuozzo.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com> --- nbd/server.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/nbd/server.c b/nbd/server.c index 5357f588f0..4752a6c8bc 100644 --- a/nbd/server.c +++ b/nbd/server.c @@ -102,6 +102,8 @@ struct NBDExport { }; static QTAILQ_HEAD(, NBDExport) exports = QTAILQ_HEAD_INITIALIZER(exports); +static QTAILQ_HEAD(, NBDExport) closed_exports = + QTAILQ_HEAD_INITIALIZER(closed_exports); /* NBDExportMetaContexts represents a list of contexts to be exported, * as selected by NBD_OPT_SET_META_CONTEXT.

Failing to meet this requirement could cause assertion failures like this if RESIZE permissions weren't requested: qemu-img: block/io.c:1910: bdrv_co_write_req_prepare: Assertion `end_sector <= bs->total_sectors || child->perm & BLK_PERM_RESIZE' failed. This was e.g. triggered by qemu-img converting to a target image with 4k request alignment when the image was only aligned to 512 bytes, but not to 4k. Turn this into a graceful error in bdrv_check_perm() so that WRITE without RESIZE can only be taken if the image size is aligned. If a user holds both permissions and drops only RESIZE, the function will return an error, but bdrv_child_try_set_perm() will ignore the failure silently if permissions are only requested to be relaxed and just keep both permissions while returning success.

In this case, a safe default of 4k is used. This is too strict for NFS, which does actually allow byte-aligned requests even with O_DIRECT. Because we can't distinguish both cases with generic code, let's just look at the file system magic and disable s->needs_alignment for NFS. This way, O_DIRECT can still be used on NFS for images that are not aligned to 4k.

We have check_hdev_writable() to check this condition and fail opening the image read-write if it's not actually writable. However, this check doesn't take auto-read-only into account, but results in a hard failure instead of downgrading to read-only where possible. Fix this and do the writable check not based on BDRV_O_RDWR, but only when this actually results in opening the file read-write. A second check is inserted in raw_reconfigure_getfd() to have the same check when dynamic auto-read-only upgrades an image file from read-only to read-write.
