From 8079b0e0f40aa0ad19e9aec7a69143ee858321a2 Mon Sep 17 00:00:00 2001 From: Ryota Ozaki Date: Fri, 25 Oct 2013 00:48:25 +0900 Subject: [PATCH] virnetsocket: fix getsockopt on FreeBSD aa0f099 introduced a strict error checking for getsockopt and it revealed that getting a peer credential of a socket on FreeBSD didn't work. Libvirtd hits the error: error : virNetSocketGetUNIXIdentity:1198 : Failed to get valid client socket identity groups SOL_SOCKET (0xffff) was used as a level of getsockopt for LOCAL_PEERCRED, however, it was wrong. 0 is correct as well as Mac OS X. So for LOCAL_PEERCRED our options are SOL_LOCAL (if defined) or 0 on Mac OS X and FreeBSD. According to the fact, the patch simplifies the code by removing ifdef __APPLE__. I tested the patch on FreeBSD 8.4, 9.2 and 10.0-BETA1.
