Andre Puschmann fa7a8fb687 rlc_am_test: add testcase for processing out-of-order status PDUs 2021-06-14 09:43:02 +02:00
Andre Puschmann 19f30aa652 rlc_am_lte: fix handling of out-of-order status PDUs 
before processing incoming status PDUs we should be checking
if the ACK_SN falls within our current Tx window. If not the PDU
will be dropped.

Without the check we were incorrectly processing the status PDU
and because the sequence number wrap around wasn't working
correctly if ACK_SN is smaller than vt_a we were corrupting
our Tx window.

Andre Puschmann d51ee722f6 rlc_am_test: add unit test for ACK_SN is outside rx window 
the test uses a malformed status PDU from a PCAP and makes
sure the RLC receiver detects such a PDU and raises a warning
 2021-06-10 10:44:18 +02:00
Andre Puschmann 878142843e rlc_am_lte: add further sanity check when creating status PDU 
the test verifies that the ACK_SN of a status PDU falls inside the
rx_window of the receiver. If not, than the RLC state has been
corrupted and the status PDU is likely invalid.

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.
