It was generated because a ref change was pushed to the repository containing the project "The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)".

As part of this change the structural checking of MGCP parameters was stopped. This means that a code like "line + 3" might access beyond the first NUL and be possible behind the msgb. Manually add size checking again. Manually jumping to the error label is not possible anymore as it has been removed. So this code will simply ignore structural errors in most cases but this is probably matching the spirit of IETF RFCs. http://cgit.osmocom.org/openbsc/commit/?id=f259bd8359de61e9c8aa92c775b95665c1a143d5 commit f259bd8359de61e9c8aa92c775b95665c1a143d5 Author: Holger Hans Peter Freyther Date: Thu May 22 14:42:09 2014 +0200 mgcp: Remove excessive logging for each frame http://cgit.osmocom.org/openbsc/commit/?id=cab6e7528c475d6aee687001a6146e5f20d8f53d commit cab6e7528c475d6aee687001a6146e5f20d8f53d Author: Pablo Neira Ayuso Date: Wed Feb 5 18:56:17 2014 +0100 mgcp: add voice muxer support This patch adds the voice muxer. You can use this to batch RTP traffic to reduce bandwidth comsuption. Basically, osmux transforms RTP flows to a compact batch format, that is later on decompacted to its original form. Port UDP/1984 is used for the muxer traffic between osmo-bsc_nat and osmo-bsc_mgcp (in the BSC side). This feature depends on libosmo-netif, which contains the osmux core support. Osmux is requested on-demand via the MGCP CRCX/MDCX messages (using the vendor-specific extension X-Osmux: on) coming from the BSC-NAT, so you can selectively enable osmux per BSC from one the bsc-nat.cfg file, so we have a centralized point to enable/disable osmux. First thing you need to do is to accept requests to use Osmux, this can be done from VTY interface of osmo-bsc_nat and osmo-bsc_mgcp by adding the following line: mgcp ... osmux on osmux batch-factor 4 This just initializes the osmux engine. You still have to specify what BSC uses osmux from osmo-bsc_nat configuration file: ... bsc 1 osmux on bsc 2 ... bsc 3 osmux on In this case, bsc 1 and 3 should use osmux if possible, bsc 2 does not have osmux enabled. Thus, you can selectively enable osmux depending on the BSC, and we have a centralized point for configuration from the bsc-nat to enable osmux on demand, as suggested by Holger. At this moment, this patch contains heavy debug logging for each RTP packet that can be removed later to save cycles. The RTP ssrc/seqnum/timestamp is randomly allocated for each MDCX that is received to configure an endpoint. ----------------------------------------------------------------------- hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)
