Andre Puschmann cc750d96ee nas: when receiving detach request, don't enter plmn_search automatically 
this patch fixes an issue with TC_9_3_1_17 after the "send attach in RRC connected" issue
has been fixed. The TC failed because the UE would always attempt to re-attach, even
after receiving an explicit detach request WITHOUT re-attach from the network.

According to TS 24.301 Sec. 5.5.2.3.2 the handling of that message largely depends
on the detach cause sent by network. Since we don't currently parse and handle
that the simplest solution here is to just enter deregistered:::null.

The patch is also part of the fix for issue #2237

Andre Puschmann 2576ada9e1 nas: do not abort attach procedure if RRC is already connected 
this is an attempt to fix issue #2237 that cause the UE to fail to
attach because the attach request wasn't resent after T3410+T3411
expired.

this was only because RRC wasn't idle at that stage and the attach
request generation was aborted.

The patch fixes this by passing the NAS PDU directly to RRC in
connected state.

The patch also converts the blocking PDU alloc to a non-blocking one.

Andre Puschmann 3573644624 srsue: fix stdout metrics print when scells aren't configured yet 
during MAC reset, scells are reset to and their PCI is set to UINT32_MAX

this patch checks the configured PCI value against UINT32_MAX and
prints "n/a" in case the scells aren't set yet.

Andre Puschmann 2be85217fd mac,ue: reset demux when restting MAC 
this potentially fixes the issue we see during HO and RLF

The issue happens because buffered DL PDUs are delivered to
RLC after reestablishing RLC that confuse the receiving
RLC entity bc the sequence numbers are very high, as opposed
to begin with zero again after reestablishment.

Andre Puschmann fd5cde525c proc_bsr: fix race condition in BSR reporting 
fix for #1934

This fixes a race condition between Stack thread and DL
PDU processing that lead to updates of the RLC buffer that
are undetected by the BSR routine.

What happens is that in a UL SCH PDU all outstanding data is transmitted
and and a LBSR with all zero buffers is sent.

14:39:47.327301 [MAC ] [D] [ 3793] BSR:   LCID=3 old_buffer=59
14:39:47.330600 [MAC ] [I] [ 3793] UL LCID=3 len=58 LBSR: b=0 0 0 0

Note that "old_buffer" isn't set to zero here.

At the same time (same TTI), the MAC PDU processing thread handles DL-SCH PDUs
that may generate new UL PDUs:

14:39:47.330749 [RLC ] [I] DRB1 Tx SDU (54 B, tx_sdu_queue_len=1)
14:39:47.330762 [RLC ] [I] DRB1 Tx SDU (54 B, tx_sdu_queue_len=2)
14:39:47.330775 [RLC ] [I] DRB1 Tx SDU (54 B, tx_sdu_queue_len=3)
..

Those PDUs are "new data" since the previous buffer state was zero.

Here is the race now between the threads, at the end of the bsr::step() function
old_buffer of each LCG is updated with the previous new_buffer, so
the buffer state of LCG=2 is now 59.

Now MAC starts the next TTI:

14:39:47.331910 [MAC ] [D] [ 3794] Running MAC tti=3794
14:39:47.331928 [MAC ] [D] [ 3794] Update Bj: lcid=0, Bj=0

14:39:47.331941 [MAC ] [D] [ 3794] Update Bj: lcid=3, Bj=-1752
14:39:47.331951 [MAC ] [D] [ 3794] BSR:   LCID=0 update new buffer=0
14:39:47.331960 [MAC ] [D] [ 3794] BSR:   LCID=1 update new buffer=0
14:39:47.331964 [MAC ] [D] [ 3794] BSR:   LCID=2 update new buffer=0
14:39:47.331971 [MAC ] [D] [ 3794] BSR:   LCID=3 update new buffer=335
14:39:47.331976 [MAC ] [D] [ 3794] BSR:    check_new_data() -> get_buffer_state_lcg(0)=0
14:39:47.331980 [MAC ] [D] [ 3794] BSR:    check_new_data() -> get_buffer_state_lcg(1)=0
14:39:47.331984 [MAC ] [D] [ 3794] BSR:    check_new_data() -> get_buffer_state_lcg(2)=59
14:39:47.331988 [MAC ] [D] [ 3794] BSR:    check_new_data() -> get_buffer_state_lcg(3)=0
14:39:47.331993 [MAC ] [D] [ 3794] BSR:   LCID=0 old_buffer=0
14:39:47.332000 [MAC ] [D] [ 3794] BSR:   LCID=1 old_buffer=0
14:39:47.332003 [MAC ] [D] [ 3794] BSR:   LCID=2 old_buffer=0
14:39:47.332007 [MAC ] [D] [ 3794] BSR:   LCID=3 old_buffer=335

And since the buffer state of LCG=2 isn't zero, the new data for LCID=3 of that LCG is considered.
So effectivly, the BSR missed the "empty" buffer state for a fraction of time and doesn't
consider the outgoing data generated in the same TTI as new. It therefore
doesn't transmit a BSR.

Andre Puschmann 465c3d9186 proc_sr: remove info log when starting SR proc 
this was a very noisy log that was printed in pretty much
every TTI because the BSR procedure starts a SR whenever
it needs to send a regular BSR. The SR is canceled when a UL
grant arrives but the log line stays there.

Since we are printing a log when we actually signal a SR
to the PHY, this line is not needed.

Andre Puschmann 1e3ad5b0dc proc_bsr: fix high priority channel trigger logic 
this fixes the trigger logic for periodic BSRs. Previously we
would always trigger the "new data for highest priority LCID"
whenever new data becomes available for a LCID for which
a BSR has already been sent.

However, a BSR should only be sent if the priority is in fact higher
(lower int number).

Andre Puschmann debbab93e8 mac_test: cosmetic change 4 years ago
Andre Puschmann e89254ad1f mac_test: fix mac_ra_test according to BSR changes 
the BSR routine had a bug in which it would generate a BSR even
before the reTx timer expires if new data becomes availble
for a LCID that already had data and a BSR was already sent.

The RA test here relies on a BSR in the generated MAC PDU to pass.

However, since after fixing the BSR bug the PDU the MUX unit
no longer generates a BSR, we need generate data for a LCID
which has higher priority than the one for which a BSR has
already been sent.

ue,sync: increase timeout for entering IDLE to 2s (#1941) 
in ZMQ runs we've seen that entering idle could take quite
a bit of time depending how quickly workers get their samples
sent or reconfigurations done.

In one example up to ~160ms

this patch increases the maximum wait time to 2s.

Andre Puschmann 3994407f46 proc_bsr: fix BSR insertion in UL PDUs 
the BSR trigger wasn't reset after includinga regular or periodic
BSR inside a PDU. This caused the muxing to include another BSR in the
next UL grant. For very small grants, for example with 6 PRBs, this
causes the UE to send way too many BSRs.

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.
