Bug description:
[Impact]
* The gfs2_jadd command (used in debian/tests/corosync)
fails with ENOTTY ("Inappropriate ioctl for device")
when the i386 packages are run on an amd64 kernel.
* The i386 kernel is gone, only amd64 is available.
* The fix introduces the compat ioctl()s for gfs2,
which landed in v5.5-rc1 thus not in Eoan/Focal.
[Test Case]
* The test steps are detailed in comment #2
based on gfs2-utils:debian/tests/corosync,
modified to be simpler and to fail either
with ENOTTY (failure) or ENOSPC (success).
[Regression Potential]
* The previous surface for this problem is
likely low, as i386 arch installs (which
is not as popular/widely used as amd64
nowadays) probably used the i386 kernel.
* The amd64-only kernel version released
is 5.3.0-17.18 dated 2019-10-10; gives
~3 month window to mid January 2020.
* So, behavior changes could theoretically
be seen on i386 installs with the newer
kernel which is amd64-only, where gfs2-utils
failed with ENOTTY and now is working fine
or failing differently (e.g. see test-case).
[Original Description]
The gfs2_jadd command (used in debian/tests/corosync)
fails with ENOTTY ("Inappropriate ioctl for device")
when the i386 packages are run on an amd64 kernel.
The i386 kernel has gone away, only amd64 is available:
- The i386 kernel build is dropped as of 5.3.0-15.16:
* Drop i386 build for 19.10 (LP: #1845714)
- Only linux-libc-dev:i386 is still built as of 5.3.0-17.18
* Re-enable linux-libc-dev build on i386 (LP: #1846508)
The last passing autopkgtests for gfs2-utils:i386 are on 5.3.0-13.14 built
for i386.
The same kernel version built for amd64 _fails_.
(so it's potentially user/kernel interface, or kernel-only.)
