[for-5.1,0/2] qemu-img convert: Fix abort with unaligned image size

Message

Kevin Wolf July 10, 2020, 2:21 p.m. UTC

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
