Xavier Arteaga af2f37d8ca SRSENB: CFI protection for all CC and fix test 4 years ago
Francisco 96ab16f1c7 s1ap fix - release old rnti (instead of new one) when a new rnti with the same tmsi is found. Furthermore, we now make sure to warn log if the enb is unable to release the old rnti 4 years ago

Francisco 32228389a9 fix latest static analysis warnings in rrc paging 4 years ago
Francisco 46cfdaf9e5 Handle case when old rnti gets removed during RRC reestablishment
This is achieved via:
- keep restarting the inactivity timer whenever a ReestablishmentRequest is received
- in case the RRC ReestablishmentComplete is very late and the old rnti was removed anyway,
  abort RRC reestablishment procedure and release new rnti

Andre Puschmann b2825d1280 mac_controller: after maxRetx disable ALL UE bearers
the reasoning here is that the only way to recover
from the maxRetx event is the UE attempting a reestablishment.

No further traffic, neither control nor data is scheduled
until then.

Andre Puschmann b61be7878a enb,rrc: split RLF counter and timer handling for DL/UL/RLC
this patch splits the counter and timer handling for PHY DL, PHY UL,
and RLC errors and makes sure that, for example, a successful DL
does not cancel the UL RLF timer, and vice versa.

They all use the same timeout value which is user-configurable.

Francisco ef9d1b8c13 stack optimization - reduction of contention in multiqueue class
With the new design, each queue created in the multiqueue object has its own mutex.
Pushing tasks to separate queues will, therefore, not cause contention.
There will be, however, still contention between the popping thread and the pushing threads.

herlesupreeth 0f06ec0d9c Add feature to provide custom GTP-U (S1) address to be advertised inside S1AP messages
This feature is useful in scenarios where eNB is behind a NAT and EPC on public cloud
Since eNB's GTP-U can only bind to IP address visible in it's host (usually a private IP beind a NAT), it advertises the same to UE in S1AP message
resulting in traffic from EPC to eNB (DL traffic) not able to reach eNB. This commit solves this issue by providing a means to advertise a different IP address than the one GTP-U UDP socket is bound to.
This IP is usually advertised in InitialContextSetupResponse and E-RABSetupResponse.

In order to make use of this feature, use the following parameter in enb.conf

Example:

gtp_advertise_addr = 213.61.141.82

Francisco cdf72248f3 Reimplement batch-based background object/memory pool
Main changes:
- addition of pool utilities
- The node size/alignment and batch allocation threshold are now runtime arguments
- object pool and memory pool are not anymore based on the same class.
  The object pool cannot use intrusive free list because it would overwrite the object
  memory
