After the PDN disconnect failed, there was a problem

even in the same situation as 401x2 pcap.

Sukchan Lee 636170e0da Review ogs_expect() (#314) 2019-11-30 16:45:09 +09:00
Spencer Sevilla 5b59f09d9f ogs_assert to ogs_expects (#314)
* HACK: Don't retransmit InitialContextSetupReq

Related: #256

* HACK: Don't use buggy sa1p_copy()  in eNBConfigTransfer

Related: #257

* mme: don't reject with 'IMSI is unknown in HLR' (permanent reject)

* MME: Implement S6a result -> EMM cause code mapping

Closes: #263

* Spencer: modification to Haralds fix because macros are now renamed

* MME: don't assert on MAC failures of uplink NAS frames

Closes: #267

* MME: Avoid ogs_assert() in many situations

We don't want to crash the entire program just because a message
received from an external entity didn't match some of our expectations.

* compiles fine, checked DIFFs and only difference is the ogs_assert -> ogs_expect
