We do not have selftests/bpf tests for 4.9
So running 4.14 version of bpf test cases on 4.9 kernel causing these failures.

bpf# ./test_tag
test_tag: test_ta[ 2947.456687] audit: type=1701
audit(1516100826.662:8): auid=4294967295 uid=0 gid=0 ses=4294967295
pid=2672 comm="test_6
g.c:111: tag_from_fdinfo: Assertion `!ret' failed.
Aborted (core dumped)

bpf# gdb ./test_tag
<>
test_tag: test_tag.c:111: tag_from_fdinfo: Assertion `!ret' failed.
Program received signal SIGABRT, Aborted.
0x0000ffffb7e96a00 in raise () from /lib64/libc.so.6

bpf# gdb ./test_lpm_map
Starting program: /opt/kselftests/mainline/bpf/test_lpm_map
test_lpm_map: test_lpm_map.c:191: test_lpm_map: Assertion `map >= 0' failed.
Program received signal SIGABRT, Aborted.
0x0000ffffb7e96a00 in raise () from /lib64/libc.so.6

The error log is same before and after the previous stable reviews.
We have old bugs on these issues,
LKFT: 4.4 and 4.9: kselftest: bpf: test_lpm_map: Assertion `map >= 0' failed
https://bugs.linaro.org/show_bug.cgi?id=3119
LKFT: 4.4 and 4.9: kselftest: bpf: test_lpm_map: Assertion `map >= 0' failed
https://bugs.linaro.org/show_bug.cgi?id=3116
