Andre Puschmann d8fedf2e19 fix parsing of corrupted MAC PDUs 5 years ago
Andre Puschmann c5f52adfba nas: fix issue in which NAS wouldn't allow to attach once it failed
the main issue was the plmn_selected variable. the solution
was to create a function to enter the deregistered state that resets the variable
and performs all other actions that need to be performed, like clearing
EPS bearers.

The patch also extends the SS to support AT commands to enable/disable
data services and now succesfully passes TC_9_2_2_1_7

Andre Puschmann 5189bbad69 add stop() to logger_file
this allows to close and currently running log process, flush the content
to the file, continue logging during that time, open a new file
and write the new log entries to that new file

basically it allows to use the logger_file multiple times without
needing to destroy the object

this is used in the UE tester to write each testcase into a separate
log file

i.e. implement bi-directional communication

Harald Welte 2e426948fe [ENB] Add CFSB support
This commit introduces CSFB (circuit switched fall-back) capabilities to
srsLTE.  Actually, all the eNB has to do is to send a
RrcConnectionRelease with the RedirectedCarrierInfo IE.

The MME triggers this by the S1AP CS Fallback Indicator IE, which may
be present either in the Initial Context Setup Requst or in the
UE Context Modification Request.

As srsLTE has no support for the UE Context Modification Request at all
yet (!), basic support for this message is introduced in this patch.

Both Mobile Originated and Mobile Terminated CSFB with a coupel of
different UE models have been verified using this patch in a setup
consisting of srsENB attached to an undisclosed EPC connected via SGsAP
to a complete  Osmocom 2G network.

Closes: #358
Closes: #363

RRC-PHY interface (#639)
RRC-PHY interface refactor. Moved RRC-MAC interface to rrc_asn1_utils and created RRC-PHY interface also in rrc_asn1_utils. All ASN1 includes should be made from rrc_asn1_utils only keeping ue_interfaces clean of ASN1

Tested with different common and dedicated configurations (64QAM UL, 256QAM, CA, SRS enabled/disabled, etc)
