This new gprs-conf branch is intended to contain everything needed
to configure GPRS in the nanoBTS, but without implementing the SGSN/GGSN
functionality.
The SGSN/GGSN development will happen in a branch based on this branch
called "gprs-sgsn"
Use the start address inside the header entry, the start is relative
to the surrounding SDP record which is located in our base offset, when
writing it out also ignore four bytes of something (crc?).
* The length of the table is not at a fixed position. We will need
to read the offset, seek there, read the data, convert it to the
host endianes.
* Prepare the code to work with offsets of 0...
The are three policies. Accept, Reject and Defer. This will
allow to handle network connections and such from the policy
callback instead of directly acting on it.
In case of a wrongly formatted AUEP, CRCX, DLCX, MDCX the
transaction id pointer was a dangling pointer... Initialize
the transaction id to a static string..
Also fix a off by one bug. We want to extract four elements
from the MGCP message and not only 3... So a short AUEP message
made it us read too many things.
This change separates the protocol from the actual network code
(bind, forward data). This will allow to more easily hook up the
RTP code from OpenBSC and to not use local sockets at all.
The send_ methods stopped to send the MGCP messages but was
changed to actually just create a msgb_ that can be sent to
a mediagateway. Rename the methods now.
In separation of using the MGCP parsing in another context, refactor
the code to operate on a struct mgcp_config, split out the vty code
from the mgcp_protocol.c, and move the callbacks into the mgcp code.
There should be no functional changes.
* use pkg-config from openbsc to find header and library
* move sms and timer tests to libosmocore itself
* ensure "make distcheck" works on both packages
This library is intended to collect all generic/common funcitionality
of all Osmocom.org projects, including OpenBSC but also OsmocomBB
The library currently includes the following modules:
bitvec, comp128, gsm_utils, msgb, select, signal, statistics, talloc, timer,
tlv_parse, linuxlist
msgb allocation error debugging had to be temporarily disabled as it depends on
'debug.c' functionality which at the moment remains in OpenBSC
Using msgb->data only works as long as msgb->data == msgb->l2h.. In
the case of receiving a MSU unit from a E1 link, or even receiving
the IPA header we will have some non SCCP data at msgb->data and then
cast garbage to what we think is making sense..
Use msgb->l2h and everything is fine.
* Close the socket when the bind is failing.
* Close the socket when the listen is failing.
* Close the socket then the bsc_register_fd is failing.
* Return an error when the socket call is not returning a socket.
