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, jerlbeck/testing/pcu has been created at 769e802fc1114541013e2f2c058b2754a2b33a97 (commit) - Log ----------------------------------------------------------------- http://cgit.osmocom.org/osmo-pcu/commit/?id=769e802fc1114541013e2f2c058b275… commit 769e802fc1114541013e2f2c058b2754a2b33a97 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Sun Aug 16 21:36:32 2015 +0200 ms: Do not retrieve MS with IMSI 000 from the storage The IMSI '000' is used as default value for an incoming BSSGP message's IMSI IE. This can lead to the retrieval of the wrong MS object from the storage. This commit changes the get_ms method to skip the IMSI search if such an IMSI is passed as selector. Note that changing the default value in the BSSGP code does not help here.

This commit changes gprs_rlcmac_dl_tbf::handle() to use update_ms instead.

This is caused by blindly setting the TLLI without querying the MS storage to avoid inconsitencies. This leads to several entries in the MS storage that are assigned to the same TLLI. If that happens, 'show ms all' can display multiple entries with the same TLLI (note that an MS object can belong to several TLLIs, so there might be an intersection that is not visible in the list) or 'show tbf all' can show entries with MS_CLASS == 0 in some cases. This commit changes update_ms() to merge and clean up old entries that belong to the given TLLI if they exist. Some data (like the MS class) is copied to the new MS object. Note that TBF belonging to the old MS object are deleted immediately if they have not registered a timer.

This may cause freezing or really slow TCP connections. This commit increases the default value to 4s. When the dl-tbf-idle-time is set, DL TBF are established less frequent, so smaller values (like 2s or below) can be used to improve the average latency when the load is high.

In this case, there can be 2 MS objects with different TLLI for a single real MS. The first is associated with the old TLLI and the IMSI, while the second is associated with the new TLLI and no IMSI if it had been created for the uplink TBF. When the first message with the new TLLI and the IMSI arrives from the network, the PCU is able to detect this. Currently this is not handled properly. The TBFs of the old MS object are not cleaned up properly, keeping the old MS from being deleted. This patch modifies gprs_rlcmac_dl_tbf::handle to check for this and if neccessary to move an existing DL TBF and to clean up the old MS object to ensure its deletion.

E.g. a genuis could remap "3" to "AMR" so we only know the codecs once we are at the end of the SDP file. Once we have collected everything we can select the audio codecs. The current code is compatible in that two codecs will be selected regardless of if they make any sense or not. mgcp_set_audio_info could re-use some of our codec information but then the caller in the MGCP protocol needs to be updated as well as we use the "I: GSM" information to derive the codec from there. http://cgit.osmocom.org/openbsc/commit/?id=a611da8407a609a3a426c61e7fb10230… commit a611da8407a609a3a426c61e7fb10230a9320122 Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Fri Aug 14 09:24:11 2015 +0200 mgcp: Move the SDP handling into a separate file/module The SDP file handling will get more complicated in terms of codec selection so let's remove it from the protocol handling before we start blowing it up in size. http://cgit.osmocom.org/openbsc/commit/?id=0eaad4f216637804458eacf31b0a1b10… commit 0eaad4f216637804458eacf31b0a1b10cff19e7b Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Fri Aug 14 08:54:58 2015 +0200 mgcp: Remove unused parsing data struct This struct was removed when we switched to strtok_r for parsing the data.

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, je/master has been updated discards 81f2d449be7ab8c0d4b955b6c24a8cf646278ed3 (commit) via 04e72d34f5cf885a4d6e2e6b2f2575ad09d0c007 (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 (81f2d449be7ab8c0d4b955b6c24a8cf646278ed3) \ N -- N -- N (04e72d34f5cf885a4d6e2e6b2f2575ad09d0c007) 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-pcu/commit/?id=04e72d34f5cf885a4d6e2e6b2f2575a… commit 04e72d34f5cf885a4d6e2e6b2f2575ad09d0c007 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Thu Aug 13 18:36:56 2015 +0200 tbf: Always start T3193 when changing state to GPRS_RLCMAC_WAIT_RELEASE Currently when receiving a PACKET DL ACK/NACK message with the Final Ack Indicator bit set, the TBF's state is set to GPRS_RLCMAC_WAIT_RELEASE but T3193 is only started when the LLC queue is empty. Otherwise the reuse_tbf() method is called to establish a new DL TBF. In that case, the timer is not started. This will leave the current TBF without a timer so it is potentially not released later on. This is recognisable by sticky entries in the output of the 'show tbf all' command and possibly allocation failures if there are too many of them. This commit changes the code to always start T3193 to make sure, that a timer is always active when the the state is set to GPRS_RLCMAC_WAIT_RELEASE. Note that TS 44.060, 9.3.2.6 requests to release the 'old' TBF immediately in some cases, which is not implemented by this change. This will lead to a longer reservation period of the TFI only, which is safer than reassigning it too early.
