After rearranging the four patches mentioned in the opening comment, I've isolated it to the patch ensubjected: scm: Capture the full credentials of the scm sender. The following commit from Linus's kernel is needed in 2.6.35.11 to fix this bug: commit b47030c71dfd6c8cd5cb6e551b6f7f7cfc96f6a6 Author: Eric W. Biederman <ebiederm> Date: Sun Jun 13 03:31:06 2010 +0000 af_netlink: Add needed scm_destroy after scm_send. scm_send occasionally allocates state in the scm_cookie, so I have modified netlink_sendmsg to guarantee that when scm_send succeeds scm_destory will be called to free that state.
