[LTP] [PATCH 0/5] LTP fanotify tests for v6.13

[Amir Goldstein]

Hi all,

Following tests for fanotify code in v6.13.

1. The new test case in fanotify13 fails as follows on kernels v6.6..v6.12:

fanotify13.c:282: TFAIL: handle_bytes (0) returned in event does not equal to handle_bytes (24) returned in name_to_handle_at(2)
fanotify13.c:282: TFAIL: handle_bytes (0) returned in event does not equal to handle_bytes (24) returned in name_to_handle_at(2)
fanotify13.c:282: TFAIL: handle_bytes (180003) returned in event does not equal to handle_bytes (24) returned in name_to_handle_at(2)

The fix was already backported to v6.12.10.
It was also backported to v6.6.72,
but then reverted due to a backport bug in v6.6.73
and it now staged again for v6.6.74.

2. The new variant of fanotify21 is skipped on kernels <= v6.12

This variant tests the new feature flag FAN_REPORT_FD_ERROR, which is
not effectively a bug fix.

Because this feature was added as a consequence of a bug report,
it was auto backported to v6.12.5 and to v6.6.66, but I do not
feel comfortable with adding a fix tag to force distros to backport
this feature.

Thanks,
Amir.
