[PATCH v2 1/4] lockdep: Add assertion to check if in an interrupt

by Joel Fernandes (Google)

In rcu_rrupt_from_idle, we want to check if it is called from within an interrupt, but want to do such checking only for debug builds. lockdep already tracks when we enter an interrupt. Let us expose it as an assertion macro so it can be used to assert this.

[PATCH AUTOSEL 4.19 103/192] selftests: skip seccomp get_metadata test if not real root

by Sasha Levin

From: Tycho Andersen <tycho(a)tycho.ws> [ Upstream commit 3aa415dd2128e478ea3225b59308766de0e94d6b ] The get_metadata() test requires real root, so let's skip it if we're not real root. Note that I used XFAIL here because that's what the test does later if CONFIG_CHEKCKPOINT_RESTORE happens to not be enabled. After looking at the code, there doesn't seem to be a nice way to skip tests defined as TEST(), since there's no return code (I tried exit(KSFT_SKIP), but that didn't work either...). So let's do it this way to be consistent, and easier to fix when someone comes along and fixes it.

[PATCH AUTOSEL 5.0 172/262] bpf: test_maps: fix possible out of bound access warning

by Sasha Levin

From: Breno Leitao <leitao(a)debian.org> [ Upstream commit dd9cef43c222df7c0d76d34451808e789952379d ] When compiling test_maps selftest with GCC-8, it warns that an array might be indexed with a negative value, which could cause a negative out of bound access, depending on parameters of the function. This is the GCC-8 warning: gcc -Wall -O2 -I../../../include/uapi -I../../../lib -I../../../lib/bpf -I../../../../include/generated -DHAVE_GENHDR -I../../../include test_maps.c /home/breno/Devel/linux/tools/testing/selftests/bpf/libbpf.a -lcap -lelf -lrt -lpthread -o /home/breno/Devel/linux/tools/testing/selftests/bpf/test_maps In file included from test_maps.c:16: test_maps.c: In function ‘run_all_tests’: test_maps.c:1079:10: warning: array subscript -1 is below array bounds of ‘pid_t[<Ube20> + 1]’ [-Warray-bounds] assert(waitpid(pid[i], &status, 0) == pid[i]); ^~~~~~~~~~~~~~~~~~~~~~~~~~~ test_maps.c:1059:6: warning: array subscript -1 is below array bounds of ‘pid_t[<Ube20> + 1]’ [-Warray-bounds] pid[i] = fork(); ~~~^~~ This patch simply guarantees that the task(s) variables are unsigned, thus, they could never be a negative number (which they are not in current code anyway), hence avoiding an out of bound access warning.
