From 03dc773e081c608524a0907cb1d867f792156157 Mon Sep 17 00:00:00 2001 From: Pau Espin Pedrol Date: Tue, 17 Jul 2018 12:42:12 +0200 Subject: sgsn: gtp: Use new API to send PDP DEL CTX REQ without freeing ctx locally Previous API freed the ctx immediatelly after sending the packet, which triggered a call to cb_delete_context() and dropped the entire sgsn_pdp_ctx before the PDP DEL CTX ACCEPT was received. This new API won't free the pdp ctx and we can tear down everything once we receive the ACCEPT in cb_conf. cb_conf is not automatically freed at cb_conf, user needs to free it, so we need to remove setting pctx->lib to NULL in cb_conf to avoid leaking the pdp ctx, as it needs to be freed inside sgsn_pdp_ctx_free().
