This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "UNNAMED PROJECT". The branch, master has been updated via 7c44415d785422b8f7e02059420e7c6feb89f4e9 (commit) from 0eabffdc35bef3bb678014d4c377ab8a2ac5951f (commit) Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/osmo-pcu/commit/?id=7c44415d785422b8f7e02059420e7c6… commit 7c44415d785422b8f7e02059420e7c6feb89f4e9 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Thu Mar 12 12:08:54 2015 +0100 tbf: Fix scheduling for DL Ack/Nack request Currently the DL Ack/Nack is not requested, if the last chunk of the final LLC frame in the TBF fits exactly into the remaining space of the RLC block. It is also not requested, if the RRBP flag cannot be set due to scheduling issues (single block allocation, polling already pending for this TBF, ...). So up to POLL_ACK_AFTER_FRAMES (20) RLC data blocks will have to be resent, before requesting the Ack/Nack will be retried. This commit removes the first_fin_ack parameter of create_dl_acked_block entirely and adds a request_dl_ack() method that should be called, when the TBF's state changes to FINISHED. This request will be reset, when the block has been scheduled successfully. Since the first_fin_ack hasn't been set if chunk == space, calling request_dl_ack() on both places in create_new_bsn() when the state is changed to FINISHED will also fix the first issue described above. Note that DL scheduling might not be fair concerning access to first_ts when multiple TS are used for a TBF. In theory, a TBF might never get access to first_ts in the worst case.

This way, if single blocks has been NACK'ed by the MS and the PCU has already resent the missing packets, the PCU starts retransmitting them until it has received an ACK/NACK even if other TBF have RLC blocks that need to be transmitted. This commit changes sched_select_downlink to select the next TBF with the highest priority, where blocks that are going to be resent again have a lower priority unless the window is stalling. If there is only one TBF the old behaviour is kept, since there is no other TBF that can have a higher priority. If there is much packet loss on a single phone, this modification can lead to a higher latency for that MS.

But this leads to additional logging messages, since the code in set_new_tbf and tbf_free assumes, that a real new TBF is assigned and generates log messages accordingly. This commit adds checks to avoid those messages in the above case.

This commit puts the text buffer into struct gprs_rlcmac_tbf to avoid this problem.
