Any specific area of the project related to this PR?

/area driver-modern-bpf
/area tests

Does this PR require a change in the driver versions?

What this PR does / why we need it:

This PR tries to address multiple drivers_test failures on ppc64le.
Remaining failures (for modern bpf):

[  FAILED  ] 12 tests, listed below:
[  FAILED  ] SyscallExit.clone3X_child
[  FAILED  ] SyscallExit.clone3X_child_clone_parent_flag
[  FAILED  ] SyscallExit.clone3X_child_new_namespace_from_child
[  FAILED  ] SyscallExit.cloneX_child
[  FAILED  ] SyscallExit.creatX_success
[  FAILED  ] SyscallExit.forkX_child
[  FAILED  ] SyscallExit.getrlimitX_success
[  FAILED  ] SyscallExit.openX_success
[  FAILED  ] SyscallExit.openatX_success
[  FAILED  ] SyscallExit.openatX_create_success
[  FAILED  ] SyscallExit.prlimit64X_success
[  FAILED  ] SyscallExit.socketcall_sendmsgX_fail
  • Clone + fork related tests fail because of page faults
  • creatX_success, openX_success, openatX_success, openatX_create_success fail because of some weird thing happening while encoding/decoding dev parameter:
Expected equality of these values:
 *(T*)(m_event_params[m_current_param].valptr)
   Which is: 29
 param
   Which is: 37

Expected equality of these values:
  size
    Which is: 80
  expected_size
    Which is: 40

Huge thanks to @Andreagit97 for helping me debugging these weird issues!

Old bpf situation:

[  FAILED  ] 11 tests, listed below:

[  FAILED  ] SyscallExit.clone3X_child_new_namespace_from_child
[  FAILED  ] SyscallExit.cloneX_child

Same except for SyscallExit.socketcall_sendmsgX_fail that is skipped on bpf and kmod.

After #1737 got merged, we are now at:

[  FAILED  ] 11 tests, listed below:
[  FAILED  ] SyscallExit.clone3X_child
[  FAILED  ] SyscallExit.clone3X_child_clone_parent_flag
[  FAILED  ] SyscallExit.clone3X_child_new_namespace_from_child
[  FAILED  ] SyscallExit.cloneX_child
[  FAILED  ] SyscallExit.creatX_success
[  FAILED  ] SyscallExit.forkX_child
[  FAILED  ] SyscallExit.openX_success
[  FAILED  ] SyscallExit.openatX_success
[  FAILED  ] SyscallExit.openatX_create_success
[  FAILED  ] SyscallExit.sendmsgX_fail
[  FAILED  ] SyscallExit.socketcall_sendmsgX_fail

Last 2 fails with same reason:

Expected equality of these values:
  size
    Which is: 80
  expected_size
    Which is: 40

only on modern BPF (only driver that does not skips checking parameters).
