[tor/release-0.2.9] Add getpid() to the seccomp2 sandbox.
by nickm＠torproject.org 08 May '17

08 May '17

commit 99e943998dcfd1263301224104ef98596325f9f2 Author: Nick Mathewson <nickm(a)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(+) diff --git a/src/common/sandbox.c b/src/common/sandbox.c index ebc843e..95c9f83 100644 --- a/src/common/sandbox.c +++ b/src/common/sandbox.c @@ -155,6 +155,7 @@ static int filter_nopar_gen[] = { #ifdef __NR_getgid32 SCMP_SYS(getgid32), #endif + SCMP_SYS(getpid), #ifdef __NR_getrlimit SCMP_SYS(getrlimit), #endif
