commit 0e5378feeca5d67b7e8f5550eaf7fcd87b8f59ea Author: Nick Mathewson nickm@torproject.org Date: Mon Nov 12 08:23:58 2018 -0500
seccomp2: Add "shutdown" to the list of permitted system calls.
We don't use this syscall, but openssl apparently does.
(This syscall puts a socket into a half-closed state. Don't worry: It doesn't shut down the system or anything.)
Fixes bug 28183; bugfix on 0.2.5.1-alpha where the sandbox was introduced. --- changes/bug28183 | 4 ++++ src/common/sandbox.c | 2 +- 2 files changed, 5 insertions(+), 1 deletion(-)
