Francisco d574afcd33 cleanup of multiqueue unused methods, and made queue_handle move semantics correct 4 years ago
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.

Francisco 7ced0e73eb rlc,bugfix - avoid accessing the PDCP info of RLC segments when the PDCP has already discarded the respective PDCP SN. 4 years ago
Andre Puschmann 597729ac53 rlc: always remove PDCP SNs from undelivered queue 
if RLC PDUs with certain PDCP SNs were already in flight
when their discard timer at PDCP expires, they weren't
remove from the undelivered_sdu_info_queue causing
indesired log entries like:

08:08:52.455280 [RLC    ] [W] PDCP_SN=2103 already marked as undelivered

when the SN was sent again (after wrap around).

The patch makes sure to always try to delete the PDCP SN
from the queue. It should fix (at least partly) #2560

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
