From 4892c10b273119e20c536285663f1ded6b6ff3fe Mon Sep 17 00:00:00 2001 From: sbose <[email protected]> Date: Mon, 11 Feb 2013 15:39:22 +0100 Subject: [PATCH] ipa-kdb: Free talloc autofree context when module is closed Currently kdb5kdc crashes on exit if the ipadb KDB modules is loaded and trusts are configured. The reason is the talloc autofree context which get initialised during the ndr_push_union_blob() call. On exit the KDC module is unloaded an later on atexit() tries to free the context, but all related symbols are already unloaded with the module. This patch frees the talloc autofree context during the cleanup routine of the module. Since this is called only at exit and not during normal operations this is safe even if other KDC plugins use the talloc autofree context, e.g. via some Samba libraries, as well.
