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 "The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)". The branch, fairwaves/master has been updated discards e878d07c1c219441676a046d2d267c48d1d618e2 (commit) discards b26b74924dc155f0b36d9940d325ffb1900d8f46 (commit) via 85439534961c34f620117979d658bdbb760bafb3 (commit) via 3cc7d2b50d8e6d8834135adbb984c90500cacaae (commit) This update added new revisions after undoing existing revisions. That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (e878d07c1c219441676a046d2d267c48d1d618e2) \ N -- N -- N (85439534961c34f620117979d658bdbb760bafb3) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. 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/openbsc/commit/?id=85439534961c34f620117979d658bdbb… commit 85439534961c34f620117979d658bdbb760bafb3 Author: Ivan Kluchnikov <kluchnikovi(a)gmail.com> Date: Tue Jul 21 11:40:08 2015 +0300 sub: Add the ability to set prefix for randomly generated extensions Prefix is added before randomly generated extension.

This leads to LLC queues being constantly filled under load, increasing the latency up to the maximum life time. This kind of bufferbloat hinders TCP's congestion avoidance algorithms. To keep the queues short, the CoDel active queue management algorithm can be used. This commit changes to llc_dequeue method to apply the CoDel algorithm to selectively drop LLC frames before they passed to the TBF layer to be encoded in BSNs. This feature is currently disabled by default. The CoDel state is managed per MS since the LLC queues are also kept in the MS objects. Note that there is still some buffering in the TBF objects, in the worst case (CS4) 3.5kByte + LLC-MTU octets are stored there. The resulting additional packet delay is not (yet) taken into account for CoDel. Also note that configuration changes are applied to new MS objects only. The following VTY commands are added to the 'pcu' node: - queue codel activates CoDel, the interval is selected by the implementation - queue codel interval <1-1000> activates CoDel with a fixed interval given in centiseconds (10ms-10s) - no queue codel deactivates CoDel Which interval value to use is still an open issue. For high speed links (e.g. Ethernet), CoDel suggests 100ms. For slower links, the expected RTT is recommended. The current implementation uses a default value of 2000ms. Measurements: Note that the following measurements depend on several other factors, most notably the interaction with the SGSN's flow control. They are just examples to give an idea how CoDel might influence some parameters. The measurements have been done with a single E71, first with a running ping only (Idle), then with an additional TCP download of a 360k file (Busy). The CoDel interval was set to 1s. - Idle : ping ~400ms, avg queue delay 0ms, dropped 0 - Busy, No CoDel: ping ~6s, avg queue delay 4-6s, dropped 0, scheduled 948, duration 54s - Busy, CoDel: ping 500-1500ms, avg queue delay ~600ms, dropped 77, scheduled 1040, duration 60s More measurements with two MS downloading in parallel (two independant measurements per case). - Busy, No CoDel: dropped 0, scheduled 1883, duration 121s dropped 19, scheduled 2003, duration 133s - Busy, CoDel: dropped 22, scheduled 1926, duration 116s dropped 22, scheduled 1955, duration 108s Sponsored-by: On-Waves ehf http://cgit.osmocom.org/osmo-pcu/commit/?id=4f666bc1136eb581d11dc4774192872… commit 4f666bc1136eb581d11dc47741928725c76b09c6 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Mon Jul 20 12:40:42 2015 +0200 llc: Add CoDel AQM implementation This commit adds an implementation of the CoDel algorithm based on the reference pseudocode presented in http://queue.acm.org/appendices/codel.html.

This commit enables CoDel on start up with the default interval time, equivalent to the 'queue codel' VTY command. To disable CoDel, use the 'no queue codel' command.

This leads to LLC queues being constantly filled under load, increasing the latency up to the maximum life time. This kind of bufferbloat hinders TCP's congestion avoidance algorithms. To keep the queues short, the CoDel active queue management algorithm can be used.

This, in combination with gcc optimizing the "switch(multiframe)"-statement into a LUT without bounds- checking (since using an uninitialized value is undefined behavior) caused neigh_task to be filled with an out-of- bounds value, eventually crashing the TDMA scheduler.
