bpf: test_maps: fix possible out of bound access warning

2019-04-05T20:34:42Z

[ 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[ + 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[ + 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.
