Andre Puschmann fab86382c1 mac,rrc: add interface to set SR config explicitly without touching any other MAC function
when releasing PUCCH/SRS (see 5.3.13 in 36.331) we need to reset the SR config as well.
In our case, SR is handled by MAC so we need to (re-)configure MAC, not all of
MAC though, just SR.

Sylvain Munaut 6ce5863f03 test/tft_test: Add a combined test for IPv6 packets 2020-09-28 16:08:28 +02:00
Sylvain Munaut 9ba8b62972 test/tft_test: Update filter test suite
The “IPv4 local address type” filter should be 9 bytes since it includes
not only the ip address, but also its subnet mask.

Quoting from 3GPP TS 24.008 10.5.6.12:
"""
 For "IPv4 remote address type", the packet filter component value field
 shall be encoded as a sequence of a four octet IPv4 address field and a
 four octet IPv4 address mask field. The IPv4 address field shall be
 transmitted first. For "IPv4 local address type", the packet filter
 component value field shall be encoded as defined for "IPv4 remote
 address type".
"""

Same for the ToS which also includes a 1 byte mask value

[REBASE] Make PHY non-blocking and fefactor HO procedure (#1753)
* Make PHY non-blocking and fefactor HO procedure

* makes entire PHY non-blocking through command interface
* adds dedicated queue for cell_search/cell_select commands
* refactor HO procedure to run faster, in one stack cycle. Looks closer to the specs
* force ue to always apply SIB2 configuration during reestablishment
* Run update_measurements in all workers

faluco f0d651ae8e - Fixed a leak in the MME class not releasing the static byte buffer pool.
- Now the pool gets destroyed on program exit using a unique_ptr.
- Removed manual cleanup() calls in all the code base to free the pool instance.

Andre Puschmann a7911f0dab pdcp,rlc: refactor SDU queueing policy
this patch refactors the SDU queuing and dropping policy of the RLC and PDCP layer.
the previous design had issues when packets have been generated at a higher
rate above the PDCP than they could be consumed below the RLC.

When the RLC SDU queues were full, we allowed two policies, one to block on the write
and the other to drop the SDU. Both options are not ideal because they either
lead to a blocking stack thread or to lost PDCP PDUs.

To avoid this, this patch makes the following changes:

* PDCP monitors RLC's SDU queue and drops packets on its north-bound SAP if queues are full
  * a new method sdu_queue_is_full() has been added to the RLC interface for PDCP
* remove blocking write from pdcp and rlc write_sdu() interface
  * all writes into queues need to be non-blocking
  * if Tx queues are overflowing, SDUs are dropped above PDCP, not RLC
* log warning if RLC still needs to drop SDUs
  * this case should be avoided with the monitoring mechanism
