The asserts had been hit at 32C3 and the fixes were created by Jacob and had been tested at the convention. http://cgit.osmocom.org/openbsc/commit/?id=5ac4aadd1a9613db6592bf8a82ddbbf2… commit 5ac4aadd1a9613db6592bf8a82ddbbf273ab2c3e Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Mon Jan 4 18:43:38 2016 +0100 sgsn: Re-add searching for MM ctx based on TLLI / P-TMSI matches If an MM context cannot be found based on BBSGP info and a RA UPDATE REQUEST is received, try to find an MM context with an P-TMSI from which the TLLI could have been derived. This also checks, whether the routing area matches. This is similar to the old behaviour removed by the commits "sgsn: Only look at TLLIs in sgsn_mm_ctx_by_tlli" and "sgsn: Remove tlli_foreign2local", except that this will only be done for RA UPDATE REQUESTs now.

With the changes made to sgsn_mm_ctx_by_tlli this will never find a MM context if the routing area has changed. If the routing area has not changed, the mmctx has already been found if it exists. This commit splits searching for an MM context (if it hasn't been found already) from checking, whether a found one can really be used. The actual search is removed, so that the MS will be forced to restart the attach procedure, which is less efficient but safe.

On the other hand, tlli_new is not checked at all. This commit changes the function to only look at mmctx->tlli, mmctx->tlli_new, and the routing area.

The send_0408_message function used in the tests does not set this, so the RA identifier is always 0-0-0-0. This commit adds a parameters to pass the RAID and adds missing dummy RAIDs. Note that the CI can still not be set and thus is always 0.

This seems to sometimes introduce inconsisties, possibly leading to a failing assertion in _bssgp_tx_dl_ud. This mapping should probably reduce the allocation of additional LLME during routing area changes. This commit removes tlli_foreign2local.
