It is one of these changes that should have never worked but did
for a long time. Only recently a corrupted GTP message was seen.
The code in ccd2312d10 tried to
solve the right problem but was deeply flawed.
* Make the code operate on the copied message and not the original
one that is deleted by the underlaying layers on return
* Add an out variable to determine if the msgb should be deleted
and assume that by default it will be deleted.

About OpenBSC ============= OpenBSC started as a minimalistic all-in-one implementation of the GSM Network, with particular emphasis on the functionality typically provided by the BSC, MSC, HLR, VLR and SMSC. Today it is a growing suite of libraries and programs, implementing protocol stacks and functional elements, including * OsmoBSC - a pure GSM BSC, speaking Abis/IP to the BTS and A/IP to the MSC * OsmoBSC-MGCP - MGCP helper to the OsmoBSC software * OsmoNITB - a BSC+MSC+VLR+HLR+SMSC "Network in the box". * OsmoCSCN - a voice CN with A/IP and IuCS/IP towards the BSC and/or HNB-GW * OsmoSGSN - a GPRS SGSN with Gb/IP and IuPS/IP towards the PCU and/or HNB-GW * Osmo-GbProxy - a Proxy to aggregate many Gb links as one Gb link to the SGSN * OsmoBSCNAT - a gateway aggregating many A links as one A link to the MSC * OsmoGTPHUB - a hub aggregating many GTP links (between SGSN and GGSN) * ipaccess-utils - some tools to discover + configure ip.access nanoBTS * bs11_config - a tool to configure the Siemens BS-11 microBTS Various interfaces towards the BTS are supported, among which are: * Classic A-bis over E1 using a mISDN based E1 interface. In other words, you can connect existing GSM Base Transceiver Station (BTS) through E1 to OpenBSC. So far, we have made it work with the Siemens BS-11, various Ericsson RBS2xxx BTS models and the Nokia MetroSite. * A-bis over IP as used by the ip.access nanoBTS product family as well as the Open Source OsmoBTS software (by the same authors as OpenBSC). OsmoBTS in turn supports various transceiver hardware, including the sysmoBTS product family, as well as SDR transceivers supported by OsmoTRX, such as the UmTRX or USRP boardss. * IuCS and IuPS over IP towards an HNB-GW (see osmo-iuh) for UMTS (3G) voice and data links.
