Sukchan Lee aa81bb2c89 Fix the bug #619
When missing Activate default EPS bearer context accept
between UE and eNB, MME's exception handler has a bug.

So I've fixed it!

Sukchan Lee 1bed0d5872 [#568] Add GTP-U Error Indication Handling
So far, no operation was performed when Error Indication was received
from eNodeB. For that reason, I solved #568 issues by controlling
the MME to prevent this from happening.

Now, when GTP-U Error Indication is received, MME and SGW are implemented
to do what they have to do. I hope that the network can be restored
by responding appropriately even if Error Indication occurs.

Sukchan Lee 81856afff9 Fix the bug for PTI mismatch (#355)
If PDN connectivity/disconnect or Bearer Resource Modification,
MME should set UE's PTI.

And other case, PTI should set to be 0(unassigned).

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
