| * | UPSTREAM: seccomp: always propagate NO_NEW_PRIVS on tsync | Jann Horn | 2017-04-13 | 1 | -11/+11 |
| | | | | | | | | | | | | | | | | | Before this patch, a process with some permissive seccomp filter that was applied by root without NO_NEW_PRIVS was able to add more filters to itself without setting NO_NEW_PRIVS by setting the new filter from a throwaway thread with NO_NEW_PRIVS.

| * | UPSTREAM: seccomp: cap SECCOMP_RET_ERRNO data to MAX_ERRNO | Kees Cook | 2017-04-11 | 1 | -1/+3 |
| | | | | | | | | | | | | | | | | | | | The value resulting from the SECCOMP_RET_DATA mask could exceed MAX_ERRNO when setting errno during a SECCOMP_RET_ERRNO filter action. This makes sure we have a reliable value being set, so that an invalid errno will not be ignored by userspace. Signed-off-by: Kees Cook <keescook@chromium.org> Reported-by: Dmitry V.
