From 1da8ac7c49fb2879ba95006d8bd1095e6870ea1a Mon Sep 17 00:00:00 2001 From: Alexei Starovoitov Date: Fri, 10 Mar 2017 22:05:55 -0800 Subject: [PATCH] selftests/bpf: fix broken build Recent merge of 'linux-kselftest-4.11-rc1' tree broke bpf test build. None of the tests were building and test_verifier.c had tons of compiler errors. Fix it and add #ifdef CAP_IS_SUPPORTED to support old versions of libcap. Tested on centos 6.8 and 7 Signed-off-by: Alexei Starovoitov Acked-by: Daniel Borkmann Tested-by: Daniel Borkmann Signed-off-by: David S.
