[PATCH] openbsc[master]: gprs_gmm.c: Don't try to de-reference NULL mmctx
by Neels Hofmeyr 02 Jun '16

02 Jun '16

Review at https://gerrit.osmocom.org/168 gprs_gmm.c: Don't try to de-reference NULL mmctx There was a comment in the code that certain GMM messages require a valid mmctx pointer. However, nothing actually checked if that pointer was in fact non-NULL. We plainly crashed if a MS would send us the wrong message in the wrong state. Original patch by Harald Welte, but it broke message validity checking, resulting in sgsn_test failure. This re-implements the NULL check in a different way, as explained by in-code comment.

[PATCH] openbsc[master]: gprs_gmm.c: Make TLLI handling specific to Gb interface
by Neels Hofmeyr 02 Jun '16

02 Jun '16

Review at https://gerrit.osmocom.org/169 gprs_gmm.c: Make TLLI handling specific to Gb interface Soem of the operations we perform in the GMM layer are specific to the GPRS/EDGE radio access network and its Gb interface. Let's make them conditional to that in preparation of supporting an Iu interface.
