BugLink: https://bugs.launchpad.net/bugs/1849281 The ifndef for SECCOMP_USER_NOTIF_FLAG_CONTINUE was placed under the ifndef for the SECCOMP_FILTER_FLAG_NEW_LISTENER feature. This will not work on systems that do support SECCOMP_FILTER_FLAG_NEW_LISTENER but do not support SECCOMP_USER_NOTIF_FLAG_CONTINUE. So move the latter ifndef out of the former ifndef's scope. 2019-10-20 11:14:01 make run_tests -C seccomp make: Entering directory '/usr/src/perf_selftests-x86_64-rhel-7.6-0eebfed2954f152259cae0ad57b91d3ea92968e8/tools/testing/selftests/seccomp' gcc -Wl,-no-as-needed -Wall seccomp_bpf.c -lpthread -o seccomp_bpf seccomp_bpf.c: In function ‘user_notification_continue’: seccomp_bpf.c:3562:15: error: ‘SECCOMP_USER_NOTIF_FLAG_CONTINUE’ undeclared (first use in this function) resp.flags = SECCOMP_USER_NOTIF_FLAG_CONTINUE; ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ seccomp_bpf.c:3562:15: note: each undeclared identifier is reported only once for each function it appears in Makefile:12: recipe for target 'seccomp_bpf' failed make: *** [seccomp_bpf] Error 1 make: Leaving directory '/usr/src/perf_selftests-x86_64-rhel-7.6-0eebfed2954f152259cae0ad57b91d3ea92968e8/tools/testing/selftests/seccomp' Reported-by: kernel test robot <rong.a.chen@intel.com> Fixes: 0eebfed2954f ("seccomp: test SECCOMP_USER_NOTIF_FLAG_CONTINUE") Cc: linux-kselftest@vger.kernel.org Signed-off-by: Christian Brauner <christian.brauner@ubuntu.com> Reviewed-by: Tycho Andersen <tycho@tycho.ws> Link: https://lore.kernel.org/r/20191021091055.4644-1-christian.brauner@ubuntu.com Signed-off-by: Kees Cook <keescook@chromium.org> (cherry picked from commit 2aa8d8d04ca29c3269154e1d48855e498be8882f https://git.kernel.org/pub/scm/linux/kernel/git/kees/linux.git) Signed-off-by: Christian Brauner <christian.brauner@ubuntu.com> --- tools/testing/selftests/seccomp/seccomp_bpf.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-)
