Subject: [PATCH for-5.1 0/2] qemu-img convert: Fix abort with unaligned image size
Date: Fri, 10 Jul 2020 16:21:47 +0200 [thread overview]
Message-ID: <20200710142149.40962-1-kwolf@redhat.com> (raw)
Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1834646
Patch 1 fixes the assertion failure by failing gracefully when opening
an image whose size isn't aligned to the required request alignment.
Patch 2 relaxes the restrictions for NFS, which actually supports byte
alignment, but incorrectly gets a 4k request alignment in the file-posix
block driver.
Kevin Wolf (2):
block: Require aligned image size to avoid assertion failure
file-posix: Allow byte-aligned O_DIRECT with NFS
