openbsc.git branch master updated. 0.14.0-14-g6f6cbf7

On busy multi BTS cells (e.g. rhizomatica) with wifi backhaul the timeout we set to wait for a RF Channe Release ACK is sometimes too little and channels are marked broken that look to be okay (besides the still to be determined delay). In case of a sysmoBTS we now know that we can change the state of a broken channel back to normal in case we do receive the right response. Manually verified using the Smalltalk BTS code PackageLoader fileInPackage: 'FakeBTS' bts := FakeBTS.BTS new. bts btsId: '1903/0/0'. bts connect: 'localhost'. bts waitForBTSReady. test := FakeBTS.OpenBSCTest new. test bts: bts. test requireAnyChannel ... wait for NITB output <0004> abis_rsl.c:223 (bts=0,trx=0,ts=0,ss=0) Timeout during deactivation! Marked as broken. ... process pending messages stdin next <0004> abis_rsl.c:735 (bts=0,trx=0,ts=0,ss=0) CHAN REL ACK for broken channel. Releasing it. So the channel went from broken to unallocated. ----------------------------------------------------------------------- Summary of changes: openbsc/include/openbsc/gsm_data.h | 11 +++++++++++ openbsc/src/libbsc/abis_rsl.c | 17 ++++++++++++++--- 2 files changed, 25 insertions(+), 3 deletions(-) hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)

The same messages need to be scanned and the same access-lists will be looked at. In the future we might even split traffic based on the IMSI. Begin with moving the code to a new top level directory and then renaming and removing the nat dependency. ----------------------------------------------------------------------- hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)

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 (2fa8bf59113913fedd9f91a0fee8d9bd199ac347) \ N -- N -- N (7be39dc3b0fff33e4c1b231fde25cc90e9558440) 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/osmo-gmr/commit/?id=7be39dc3b0fff33e4c1b231fde25cc9… commit 7be39dc3b0fff33e4c1b231fde25cc90e9558440 Author: Sylvain Munaut <tnt(a)246tNt.com> Date: Sun Mar 29 20:59:06 2015 +0200 gr-gmr1/rach_demod: Improve initial frequency estimation Signed-off-by: Sylvain Munaut <tnt(a)246tNt.com> http://cgit.osmocom.org/osmo-gmr/commit/?id=a7209fc0cce4df4468797c2a608691c… commit a7209fc0cce4df4468797c2a608691c62399c403 Author: Sylvain Munaut <tnt(a)246tNt.com> Date: Sun Mar 29 20:56:53 2015 +0200 gr-grm1/rach_detect_fft: Fix the direction of peak offset compensation Signed-off-by: Sylvain Munaut <tnt(a)246tNt.com> http://cgit.osmocom.org/osmo-gmr/commit/?id=a2a370a46eedaf22b0b81cb473828fe… commit a2a370a46eedaf22b0b81cb473828fe47ff17d3c Author: Sylvain Munaut <tnt(a)246tNt.com> Date: Sun Mar 29 20:56:29 2015 +0200 gr-gmr1: Add a tag with the time of RACH and write it to file Signed-off-by: Sylvain Munaut <tnt(a)246tNt.com> http://cgit.osmocom.org/osmo-gmr/commit/?id=0803baa9eac94f1566394715a49569e… commit 0803baa9eac94f1566394715a49569ebacd2164a Author: Sylvain Munaut <tnt(a)246tNt.com> Date: Sun Mar 29 20:55:44 2015 +0200 gr-gmr1/rach_detect_fft: Use a global constant for freq key Signed-off-by: Sylvain Munaut <tnt(a)246tNt.com> http://cgit.osmocom.org/osmo-gmr/commit/?id=531665e38431f0967e1ef652ab4fb5c… commit 531665e38431f0967e1ef652ab4fb5c3ee87283e Author: Sylvain Munaut <tnt(a)246tNt.com> Date: Sun Feb 22 20:43:15 2015 +0100 gr-gmr1: Make use of that new text sink in the default GRC app Signed-off-by: Sylvain Munaut <tnt(a)246tNt.com> http://cgit.osmocom.org/osmo-gmr/commit/?id=5763a1ecafb5889c99dfca99cddc336… commit 5763a1ecafb5889c99dfca99cddc3366f05415d3 Author: Sylvain Munaut <tnt(a)246tNt.com> Date: Sun Feb 22 20:42:49 2015 +0100 gr-gmr1: Add special file sink to record RACH in text format Signed-off-by: Sylvain Munaut <tnt(a)246tNt.com> http://cgit.osmocom.org/osmo-gmr/commit/?id=6e1160b9e6ee6b48f45d794637e6a25… commit 6e1160b9e6ee6b48f45d794637e6a25b6f6541b3 Author: Sylvain Munaut <tnt(a)246tNt.com> Date: Fri Jan 30 10:11:02 2015 +0100 gr-gmr1: Make use of the new delimited burst feature Signed-off-by: Sylvain Munaut <tnt(a)246tNt.com> http://cgit.osmocom.org/osmo-gmr/commit/?id=d0b41f0780ad1c3cdf61211b1ab3243… commit d0b41f0780ad1c3cdf61211b1ab32439eae8289f Author: Sylvain Munaut <tnt(a)246tNt.com> Date: Fri Jan 30 10:07:22 2015 +0100 gr-gmr1: Import new burst_to_tagged_stream logic Note that this cheats a little since I use the output buffer as temporary storage (i.e. writing samples to it and not telling GR until later ...)

The 400ms result from requesting an DL Ack/Nack every 20 RLC blocks until all pending LLC frames have been sent. Especially TCP's slow start mechanism can lead to a high delay at the start of the connection, since the sender will eventually stop after having sent the first packets (up to 4 (RFC2581) or 10 (RFC6928)). This commit modifies append_data() to (re-)start a timer every time it handles an LLC packet and to request an Ack/Nack every time it expires. So if the server ceases to send IP packets, the MS is polled in the assumption, that the server is waiting for an ACK. The following VTY commands are added (pcu node): - queue idle-ack-delay <1-65535> timeout in centiseconds - no queue idle-ack-delay disable this feature (default) A sensible value is 10 (100ms) that at gave promising results when testing locally. Sponsored-by: On-Waves ehf http://cgit.osmocom.org/osmo-pcu/commit/?id=0c1c8778dfdda80222d30b903d62156… commit 0c1c8778dfdda80222d30b903d62156adb6927c4 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Fri Mar 20 12:02:42 2015 +0100 tbf: Use a hysteresis when discarding DL LLC frames Currently single LLC blocks are discarded when the PDU lifetime expires. If an IP packet has been fragmented either on the IP or on the LLC layer and is therefore distributed over several LLC frames, the kept fragments are transmitted and then discarded by the MS because of the missing PDU. This can cause massive IP packet loss when there are many fragmented packets (e.g. when trying 'ping -s1800' or if the GGSN chops downlink IP packets into several SNDCP packets). 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. The following VTY commands are added (pcu config node): - queue hysteresis <1-65535> set the difference between high (lifetime) and low watermark in centiseconds - no queue hysteresis disable this feature (default) Since the SGSN will most probably send all fragments of a single N-PDU without much delay between them, a value slightly above the average transmission delay jitter between SGSN and PCU is probably a sensible value to discard all fragments of a single IP packet. This is an experimental feature that might be replaced by more advanced means of active queue management in the future.

The loggingrb (ringbuffer) test case was not actually being built or ran, instead still using the normal logging test. This patch fixes the makefile, then the loggingrb testcase is changed to use the current loggingrb API so that it builds and passes.
