pespin has uploaded this change for review. ( https://gerrit.osmocom.org/c/libosmo-gprs/+/34313?usp=email ) Change subject: tbf_ul_ass_fsm: Listen only on 1 TS for PKT UL ASS when assignment done from DL TBF ...................................................................... tbf_ul_ass_fsm: Listen only on 1 TS for PKT UL ASS when assignment done from DL TBF This also fixes a memcpy writing out of bounds reported by Coverity CID#323120 in gprs_rlcmac_tbf_ul_ass_start_from_dl_tbf_ack_nack(), due to the difference of size between struct gprs_rlcmac_ul_tbf_allocation and struct gprs_rlcmac_dl_tbf_allocation. While fixing it, actually properly implement passing of the 1 only interesting TS to the tbf_ul_ass_fsm at that point in time.

[M] Change in osmocom-bb[master]: l1gprs/l1ctl: Decouple RTS.ind from DL_BLOCK.ind

by pespin

pespin has submitted this change. ( https://gerrit.osmocom.org/c/osmocom-bb/+/34310?usp=email ) Change subject: l1gprs/l1ctl: Decouple RTS.ind from DL_BLOCK.ind ...................................................................... l1gprs/l1ctl: Decouple RTS.ind from DL_BLOCK.ind Before this patch, the RTS:ind was crafted up in the stack when receiving the DL_BLOCK.ind. This created some problems since the internal low level state has to be updated in between signalling DL_BLOCK.ind and RTS.ind, as there's a fn-advnace of one block between those 2 signals (hence the timeslot allocation has to be applied at the time when the fn-advance is applied). This is actually not fixing the whole issue, since there's several timeslots and hence the following events will have the internal timeslot updated during the event in the middle, hence potentially causing problems in the remaining TS: DL_BLOCK.ind(FN=N, TS=1), RTS.ind(FN=N+4, TS=1), DL_BLOCK.ind(FN=N, TS=2) In any case, this decoupling already improves the situation and is step needed anyway towards fully fixing the problem (by, for instance, maintaining a timeslot state duplicated both for DL and Ul directions, since they drive based on differnet FN time (1 PDCH block).
