From 4b2d02d0372ae5dc88d97b06f5cfa92841cbf036 Mon Sep 17 00:00:00 2001 From: Jacob Erlbeck Date: Fri, 30 Jan 2015 11:57:25 +0100 Subject: sgsn/test: Fix memory leak in test_subscriber_gsup Currently the MM context is not deleted when a GSUP location cancellation message is processed, because the real sgsn_update_subscriber_data function has been wrapped to a dummy implementation. This commit adds an explicit call to sgsn_mm_ctx_cleanup_free which also unassigns the LLME, so the call to gprs_llgmm_assign is removed. It also adds an assertion to check that there are no talloc'ed blocks left in tall_bsc_ctx.
