It appears to depend on the run sequence of the tests. I rebooted the system, ran test_timetolive_v6, it worked okay. Ran "sctp-tests run" on a terminal, then ran test_timetolive_v6 at various intervals on another terminal. Once sctp-tests started the "=== ndatasched ===" sequence, test_timetolive_v6 failed. > > > > > On the bright side, I've run the sctp-tests from  with no > > problems > > and also the selinux-testsuite with my SCTP patch from  using an > > updated Fedora policy from  (with sctp support added), all in > > enforcing mode. > > > > Also the LTP test passed: > > cd /opt/ltp/ > > cat runtest/syscalls |grep connect01>runtest/connect-syscall > > ./runltp -pq -f connect-syscall > > .... > > > >  https://github.com/sctp/lksctp-tools > >  https://github.com/sctp/sctp-tests > >  https://marc.info/?l=selinux&m=152156947715709&w=2 > >  https://github.com/fedora-selinux/selinux-policy > > > > > > > > > > -- > > > paul moore > > > www.paul-moore.com > > > > > > > > > > > -- > To unsubscribe from this list: send the line "unsubscribe linux- > security-module" in > the body of a message to majord...@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html
