From 710708a54ccc48e168ad7d4cd401645ef9e2eb14 Mon Sep 17 00:00:00 2001 From: Michal Schmidt Date: Fri, 20 Feb 2015 02:25:16 +0100 Subject: [PATCH] shared: handle unnamed sockets in socket_address_equal() Make sure we don't inspect sun_path of unnamed sockets. Since we cannot know if two unnamed sockets' adresses refer to the same socket, just return false. --- src/shared/socket-util.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/src/shared/socket-util.c b/src/shared/socket-util.c index deecce8a8..a4e26b1d8 100644 --- a/src/shared/socket-util.c +++ b/src/shared/socket-util.c @@ -349,6 +349,10 @@ bool socket_address_equal(const SocketAddress *a, const SocketAddress *b) { break; case AF_UNIX: + if (a->size <= offsetof(struct sockaddr_un, sun_path) || + b->size <= offsetof(struct sockaddr_un, sun_path)) + return false; + if ((a->sockaddr.un.sun_path[0] == 0) != (b->sockaddr.un.sun_path[0] == 0)) return false; -- 2.30.2
