Matan Perelman 88998385eb NAS: Add configuration for LAC. 2 years ago
Andre Puschmann 994c3127fa epc,nas: remove logging error when UE sends service request in ECM_STATE_CONNECTED 
this causes errors to be logged without really failing anything.
UE might send this after a reestablishment.

Andre Puschmann f31a7d1d02 epc,nas: add handler for PDN connectivity request 
COTS phones seem to send standalone PDN connectivity request
messages even after the initial attach was complete. We don't fully support
them in the EPC but instead of logging a warning we can just send
a reject at least to keep the logs clean.

Francisco ff3fc0826b asn1 fixes and improvements 
- use const char* instead of std::string in enumerated<>::to_string() to avoid mallocs.
- Remove the use of "typedef", and use "using" keyword instead.
- Fix rrc_nr::setup_release_c<>::to_string() broken linkage.

Andre Puschmann 1a42e0b1d1 epc,nas: add error handling for all make_byte_buffer() calls 
not handling the case where allocation was failing was causing a
segfault. It seems that when doing high rate UDP iperf and
disconnecting the UE causes the buffer pool to become empty due
to the PDU buffering. Thus, causing a crash when attaching the UE again.

Pedro Alvarez 492ea2a5a8 Addressing reviewers comments to #2290. 
Removing unecessary \n for logs and changed log of PDCP info queue
 capacity to debug to avoid log spam.
Changed log level for unhandled S1AP messages from error to warning
 in EPC to avoid failing tests because of error message.
Changed usage of allocate_unique_buffer to make_unique_buffer()

Andre Puschmann 7ac0c3a8e0 epc,s1ap: don't log error when receiving UE capability info from eNB 
this fixes a warning that we had in the epc.log because we don't
explicitly handle the UE capability info message received over S1AP
from the eNB.

Since we have a strict no-error policy in many PR tests, we can't log
an error here.

Pedro Alvarez 0c20b7a455 Added support for S1AP modify bearer request support. This includes: 
- Handle received E-RAB S1AP at s1ap.cc.
 - Added methods to rrc.cc, rrc_ue.cc and rrc_bearer_cfg.cc to handle erab modify request.
 - Made RLC add_bearer() function capable of re-creating the RLC entity.
 - Send RRC reconfiguration to the UE and reply to the EPC with S1AP
   modify bearer response.

This commit also adds support to srsEPC to send S1AP modify bearer request for
testing purposes.

Andre Puschmann 9f4e1ba62d srsepc: use received NAS count to calculate MAC 
this is according to 24.301 Sec 4.4.3.3 which says the receiver
should use the sequence number included in the received message
rather a local estimate
