Subject: [GIT PULL] seccomp fixes for v5.9-rc5
Date: Fri, 11 Sep 2020 17:20:02 -0700	[thread overview]
Message-ID: <202009111718.B94EAD7@keescook> (raw)

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
