Subject: [PATCH v2 0/3] seccomp: add PR_SECCOMP_EXT and SECCOMP_EXT_ACT_TSYNC
Date: Thu, 17 Apr 2014 11:05:01 -0700 [thread overview]
Message-ID: <1397757904-30665-1-git-send-email-keescook@chromium.org> (raw)
This adds the ability for threads to request seccomp filter
synchronization across their thread group. To support this,
seccomp locking on writes is introduced, along with refactoring
of no_new_privs. Races with thread creation are handled via the
tasklist_list.
I think all the concerns raised during the discussion[1] of the first
version of this patch have been addressed. However, the races involved
have tricked me before. :)
Thanks!
