Andre Puschmann a013a2fe05 rlc_stress_test: fix bug when read_pdu was returning -1 2021-06-04 13:23:54 +02:00
Andre Puschmann c0be8187c8 rlc interface: convert entire read_pdu() interface to return uint32_t 
we had it returning int but had a bug in using the return value properly,
i.e. handling when -1 was returned in RLC TM.

Thinking about it more, it doesn't make sense to have a negative return
value here anyway. Either the RLC can return a PDU or not. If it can't the
returned lenght is zero.

Andre Puschmann a36e0477b8 rlc_am: fix status PDU packing when grant size isn't enough to send full report 
when a small grant is provided it might not be possible to fit a full status
PDU. This is currently detected while packing the PDU.

In order to avoid sending potentiall contradicting status info to the sending
entity, the fix makes sure to only transmit a small PDU acking what really
has been received so far.

This might not be optimal in terms for retx but will not corrupt any
state.

Andre Puschmann 5838ec4999 rlc_am: revert expect macro back to error log and inform higher layers 
the incidence really must be handled by the higher layers, i.e. the bearer
needs to be reestablished.

Andre Puschmann f22f4b4fbd rlc_am: fix potential stalling in RLC transmitter 
it turned out that a certain order of events can lead to
a RLC transmitter stalling because even though unacknowledged PDUs
are queued, none of them was actually considered for retx.

This can happen if a pollRetxTimer expires for a SN that, meanwhile,
has already been acknowledged. The positive lead to the deletion of
the SN from the Tx window.

The fix makes sure that when a retx for a unexisting SN is requested,
the sender will consider the next unacknowledged SN instead.

Andre Puschmann 9612bb0e14 rlc_am_test: fix status PDU test and add extra test for failure signaling 2021-06-03 21:11:47 +02:00
Andre Puschmann aaffdeb326 rrc,rlc: add method to signal protocol failure to RRC 
general-purpose method for lower layers to signal protocol
failures to higher layers, i.e. RRC.

In the current case, implement a direct release of the UE (enb) or
a reestablishment (UE).

Andre Puschmann 7ee38e6255 threads: disable thread attributes when compiled with TSAN 
TSAN doesn't work well then threads are created with attributes
thar require root rights but the process is run as normal user.

this patch avoid the thread attributes in this case. TSAN isn't going
to be used for production builds.
