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

[Petr Vorel]

Hi Amir,

> 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.

We have git freeze before new release. But IMHO this should go in.
It works well on v6.13, I'll retest it on SLES kernels.

Kind regards,
Petr
