| |
Hi Linus,
Please pull these seccomp fixes for v5.9-rc5. This fixes a rare race condition in seccomp when using TSYNC and USER_NOTIF together where a memory allocation would not get freed (found by syzkaller, fixed by Tycho). Additionally updates Tycho's MAINTAINERS and .mailmap entries for his new address.
Thanks!
-Kees
