LTP tests skipped due to missing dependencies (chromiumos tree)

[laura-nao]

Some LTP test groups running on the chromiumos tree are skipped due to missing kernel configurations or missing dependencies in the Debian root filesystem used for testing.

• capability - affects bothltp-capability-cros-kernel and ltp-fault-injection-capability-cros-kernel

Example job: https://lava.collabora.dev/scheduler/job/20245357

Errors in the log (missing deps in the rootfs):

keepcaps    1  TCONF  :  check_keepcaps.c:152: linux/securebits.h or libcap does not exist.
keepcaps    2  TCONF  :  check_keepcaps.c:152: Remaining cases not appropriate for configuration

• ima - affects both ltp-ima-cros-kernel and ltp-fault-injection-ima-cros-kernel

Example job: https://lava.collabora.dev/scheduler/job/20245363

Errors reported in the log (due to missing ima kernel config fragment):

ima_measurements 1 TINFO: Running: ima_measurements.sh 
ima_measurements 1 TINFO: Tested kernel: Linux debian-bookworm-amd64 6.6.99 #1 SMP PREEMPT_DYNAMIC Wed Oct 22 11:10:07 UTC 2025 x86_64 GNU/Linux

• input - affects both ltp-fault-injection-input-cros-kernel and ltp-fault-injection-input-cros-kernel

Example job: https://lava.collabora.dev/scheduler/job/20245366

Errors in the log (missing kernel module?):
