jmasterfunk84 68140efce4 [MME] Handle Charging Characteristics 
Found no support for HSS provided charging characteristics.  Following TS32.251 A.4:
- Use PDN level CC, if one wasn't provided then use subscription level CC
- Don't send CC in S11 if it wasn't included

Rename GTPv2C specifics to gtp2 prefix (#1485) 
In the past only GTPv2C was supported, and had the "gtp" generic prefix.
Later on, GTPv1C support was added, and "gtp1" prefix was used.
Let's move GTPv2C specific bits to have "gtp2" prefix too, and leave
"gtp" prefix for generic stuff among different GTP versions.

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
