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 "An utility library for Open Source Mobile Communications". The branch, zecke/release/0.7-dev has been created at 52354dd78567e898d5dd114380a17990ce1608f8 (commit) - Log ----------------------------------------------------------------- http://cgit.osmocom.org/libosmocore/commit/?id=52354dd78567e898d5dd114380a1… commit 52354dd78567e898d5dd114380a17990ce1608f8 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Tue Mar 17 10:21:17 2015 +0100 bssgp: Handle BSSGP STATUS messages Currently incoming BSSGP STATUS messages are just logged and no other action is taken. This makes it impossible for higher layers to react to failures which are indicated by corresponding STATUS messages unless a timeout is triggered as a result of that failure later on. This commit adds a bssgp_rx_status() function and calls it on incoming STATUS messages. That function logs a message, increments the new BSSGP_CTR_STATUS counter if the bctx context exists and invokes an NM_STATUS status indication. The latter will allow the application to handle failures immediately. Since all STATUS messages should be handled, the function is already called in bssgp_rcvmsg and the message is no longer handled in (and will not reach) bssgp_rx_sign and bssgp_rx_ptp.

This will cause endless messages loops if both peers use this BSSGP stack implementation. This does not apply to signalling messages. This commit changes the implementation of bssgp_rx_ptp() to just do logging in this case.

The reason is, that these messages rely on a TLLI/RAI pair to identify the context and do not contain an explicit BVCI. This patch modifies bssgp_rcvmsg() to only complain about and unknown BVCI if one is given but a matching context is not found (except for RESET messages). The ctx argument is removed from the functions handling SUSPEND and RESUME since it will always be NULL then.

Since a compatible return value has been added by 'Let gprs_nsvc_reset return a value', the former patch is partly reverted by this commit. The printf is now an OSMO_ASSERT.

If an IP packet has been fragmented and is therefore distributed over several LLC frames, the kept fragments are transmitted and then discarded by the MS. This can cause massive IP packet loss when there are many fragmented packets (e.g. when trying 'ping -s1800'). Also TCP recovery algorithms (default, SACK) seem to work better, if a single block of a few packets is missing instead of many single packets scattered over the TCP stream. On the other hand, discarding too many packets might disturb the congestion handling of TCP. Dropping plain TCP ACKs might also hinder flow control and congestion avoidance. This commit adds a hysteresis algorithm to the LLC discard loop. If an LLC message's age reaches the high water mark, further message's with an age above the low water mark are discarded, too. This is aborted, if a GMM, a non-UI, or a small message is detected. In these cases, that message is kept. TODO: - make low and high expiry watermarks configurable - make the keep threshold configurable http://cgit.osmocom.org/osmo-pcu/commit/?id=502bd1feea9441938498b9240522043… commit 502bd1feea9441938498b92405220437dc3a91bf Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Fri Mar 20 14:26:05 2015 +0100 tbf: Poll MS on idle DL TBFs If an MS wants to open a new UL TBF, it can either use (P)RACH or request one in a Ack/Nack message for a DL TBF (PACCH). When a TBF becomes idle (LCC queue is empty but the TBF is kept open), there aren't any Ack/Nack requests that can be used by the MS to ask for an UL TBF, therefore it has to use the RACH. This leads to many RACH requests even for a single HTTP transaction, so it takes some time to retrieve even a simple web page. This commit modifies the scheduler to regularly send Ack/Nack requests on idle DL TBFs. It does so by extending the priority based scheduling algorithm to have 5 priority levels (highest priority first): - Control block is pending - High age (100%) threshold reached (-> request Ack/Nack) - Data is waiting or there are pending Nacks - Low age (200ms) threshold reached (-> request Ack/Nack) - Pending Nacks that have been resent already - None of the above (-> send DL dummy control block) The 'age' refers to the time since since the last control block has been sent on the TBF. This high age threshold is set to dl-tbf-idle-time or to 50% of T3190 (whichever is smaller), aiming for at least a poll (and TBF shutdown) after the TBF has expired and to safely prevent expiry of T3190. So if dl-tbf-idle-time > 200ms, there will be a poll every 200ms and a final poll after dl-tbf-idle-time. On high load, the interval between polls can get higher, but the 'high age' poll should be in place. This commit implements the scheduling with respect to GSM 44.060, 9.3.1a ("Delayed release of downlink TBF").

This patch modifies create_dl_acked_block to only call create_new_bsn() if there is unsent LLC data or m_window is empty. If the TBF is in state FLOW, no unsent LLC data is left, but there are blocks left in m_window, those are resent instead.

This will lead to a new DL assignment if data is received afterwards. In addition, it is not possible to keep the PACCH open to poll the MS for UL establishment requests there. GSM 44.060, 9.3.1a suggests to delay the release of an inactive TBF for some time (max 5s). This commit mainly changes create_new_bsn() to send LLC dummy commands as filler if no LLC data is available until keep_open() returns false. The keep_open() functions returns true unless a configurable time has passed after the LLC data store drained. By default, that time is not set which causes keep_open() to always return false, so that delayed release is effectively disabled. The following VTY commands are added: - dl-tbf-idle-time <1-5000> to set the delay in ms - no dl-tbf-idle-time to disable delayed release Ticket: #556 Sponsored-by: On-Waves ehf http://cgit.osmocom.org/osmo-pcu/commit/?id=cbb1e70554a08c7d6d1307d68883bc3… commit cbb1e70554a08c7d6d1307d68883bc38a92fe4f3 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Wed Mar 25 12:21:55 2015 +0100 tbf: Insert LLC dummy command if no frame is available If a BSN is going to be created but there is no frame stored in m_llc, an empty LLC message would be created. This shouldn't happen currently, but this will be a common case, when delayed TBF release is implemented. This commit changes create_new_bsn() to create an LLC dummy command in that case and to put it into the frame buffer.

This only happens with the test case so far, but this would change when idle DL TBFs are kept open for some time. It results in empty LLC message being sent to the MS (see log below). This commit changes append_data to check for this case and to eventually use put_frame() instead of appending the LLC data to the queue.

The RLC block headers do not support stuffing, only the last block of a TBF can be used partially. LLC dummy commands are discarded by the receiver immediately, because the have an invalid FCS checksum. This commit adds the function put_dummy_frame, which puts a LLC dummy command into the frame buffer. The requested length is given as an argument, but the real length might be adjusted according to the specification (see GSM 44.064, 6.4.2.2).
