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.

faluco dacf40f63e Delete move constructor and move assignment operator explictly for mac_pcap_base and s1ap_pcap classes. 
Move emergency handlers header file into the support folder.

Refactored signal handling:
- Remove the dependency with the running static variable in the header file.
- Move implementations down to cc files.
- Allow specifying a new signal handler that will be used to stop the applications.
- Move signal handling files to support.

Jan a786d1dda0 Update security algorithms in epc.conf 
Added EEA3 and EIA3, since they were missing from the description completely.
I also included EIA0 with a remark, since my understanding is that the epc supports it, but most UEs reject it because it must only be used for unauthenticated emergency calls.

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.

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 8c9643af80 epc,gtpu: log info when IPv6 packet is sent 
we've logged in warning mode bc we don't support IPv6 but its
causing unwanted noise in the epc log file.

it's quite normal that the Linux network stack sends IPv6 router
solicitation packets, etc. So we just ignore them and that's it.
