commit 99e943998dcfd1263301224104ef98596325f9f2 Author: Nick Mathewson nickm@torproject.org Date: Wed Apr 26 12:56:06 2017 -0400
Add getpid() to the seccomp2 sandbox.
We hadn't needed this before, because most getpid() callers on Linux were looking at the vDSO version of getpid(). I don't know why at least one version of OpenSSL seems to be ignoring the vDSO, but this change should fix it.
Fixes bug 21943; bugfix on 0.2.5.1-alpha when the sandbox was introduced. --- src/common/sandbox.c | 1 + 1 file changed, 1 insertion(+)
