Francisco Paisana 665b3996bb now the phy controller handles the scenario where the phy cell selection failed to be initialized 2020-10-16 15:54:42 +01:00
Andre Puschmann 7352bfa4bd mac_test: add unit test for retxBSR timer
this test varifies the correct operation of the retxBSR timer.
the first PDU includes a long BSR to indicate more LCGs have
data to transmit. The retxBSR timer is started and subsequent
PDUs should not send a regular BSR.

After the retxBSR timer expires, a UL PDU should again include
a BSR.

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.

Andre Puschmann 829dfc4e60 metrics_stdout: fix precision calculation for 100%
the precision for 100% was causing the default value of -1 which in turn
cause to print the full precision resulting in ugly stdout plots.

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

Andre Puschmann 624c8142ad ttcn3: refactor cell handling in SS
this rather large patch changes the way cells are handled in the SS.
It moves RLC and PDCP entities to the cell map of the SS, such that each cell
has its own entities. This allows to support HO operation, for example,
in which two cells need to send SRB messages.

It also extends most of the syssim interface to include the cell name
in all commands so they can be applied on the specified cell only.

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
