When allowing to reallocate an allocated endpoint we will need
to free it first. When freeing we will free the call id and other
ids that we would have leaked otherwise.
This routine should operate on different packets and the
dummy load is smaller than a legitimate RTP header so it
is unlikely we will filture out genuine traffic.
The reason is the dummy load might be send more than once.
This can be used by higher level code to send one dummy
message from the audio port to the network. This can be
used to make the remote discover the nated port of this
endpoint.
The current setting was not properly written out, this commit is
fixing it. This includes indention, empty bts ip, wrong command
for endpoints and the wrong number (+1 as zero is allocated but
unused).
For some mode of operation it can be acceptable to reallocate
an already allocated endpoint. This can be the case when we
only deal with one call agent that is keeping track of the
endpoint but slightly confused.
Make the source address mandantory and complain about
complain when it is missing. The address is mandantory
as it needs to be put into the MGCP messages...
The logging/debugging code is generic enough to move it into libosmocore
while keeping OpenBSC specific definitions in openbsc itself.
This commit uses the logging support present in libosmocore-0.1.2,
you will have to update your library to this version.
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.
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
