[PATCH] selftests/bpf: ignore pointer types check with clang

by Andrea Righi

Building bpf selftests with clang can trigger errors like the following: CLNG-BPF [test_maps] bpf_iter_netlink.bpf.o progs/bpf_iter_netlink.c:32:4: error: incompatible pointer types assigning to 'struct sock *' from 'struct sock___17 *' [-Werror,-Wincompatible-pointer-types] s = &nlk->sk; ^ ~~~~~~~~ 1 error generated. This is due to the fact that bpftool emits duplicate data types with different names in vmlinux.h (i.e., `struct sock` in this case) and these types, despite having a different name, represent in fact the same object. Add -Wno-incompatible-pointer-types to CLANG_CLAGS to prevent these errors.

(it would not fail if disabling and already disabled) For example, PR_SET_THP_DISABLE/PR_SET_NO_NEW_PRIVS doesn't fail if already set. -- Thanks, David / dhildenb

[PATCH] selftests/resctrl: Fix incorrect error return on test complete

by Reinette Chatre

An error snuck in between two recent conflicting changes: Until recently ->setup() used negative values to indicate normal test termination. This was changed in commit fa10366cc6f4 ("selftests/resctrl: Allow ->setup() to return errors") that transitioned ->setup() to use negative values to indicate errors and a new END_OF_TESTS to indicate normal termination. commit 42e3b093eb7c ("selftests/resctrl: Fix set up schemata with 100% allocation on first run in MBM test") continued to use negative return to indicate normal test termination. Fix mbm_setup() to use the new END_OF_TESTS to indicate error-free test termination.
