The LTP syscalls mseal02 and shmctl03 failed only with compat mode testing with 64-bit kernel with 32-bit rootfs combination.
Would it be possible to detect compat mode test environment and handle the test expectation in LTP test development ?
Test case: - ltp-syscalls/mseal02 - ltp-syscalls/shmctl03
Test environments: - qemu-arm64-compat - qemu-x86_64-compat - x86-compat
Regression Analysis: - New regression? Yes - Reproducibility? Yes
Test regression: LTP mseal02.c:45: TFAIL: mseal(0xf7a8e000, 4294963201, 0) expected EINVAL: ENOMEM (12)
Test regression: LTP shmctl03.c:33: TFAIL: /proc/sys/kernel/shmmax != 2147483647 got 4294967295
