T3109 is started when the SACCH is deactivated. It is stopped when
the phones sends the DISC/UA/UM on LAPDm for the main signalling
link. In case of timeout the abnormal release procedure will be
initiated. Make sure to not issue the SACCH Deactivate twice to
avoid confusing the equipment.
This is still not fully spec compliant. In case of a timeout the
abnormal release handling will be started which involves starting
T3111+2. The error handling should be split out of the rf channel
release method, e.g. lchan_release should be called and check if
the channel release was already initiated.
* Release all channels with SAPI > 0 with the "local end release"
(as of NOTE 1 of GSM 04.08).
* No need to wait for all SAPIs to be torn down and the normal
REL_IND/REL_CONF will call rsl_handle_release and the channel
should be released.
* Update the documentation
In case of a reset (loss of the BTS) close down all remaining
RTP Proxy sockets. In case of a lchan_free shout if the rtp
proxy is still open. I would prefer if the proxy code sits inside
the gsm subscriber connection.
In case of a failed channel we still want the channel to not be
re-allocated right away but keep it closed/unused for (T3109 + T311).
rsl_rx_rf_chan_rel_ack has a check to not set the channel to S_NONE in
case the channel is in the error state. Add the camp Harald added a timer
to set the channel back to the none state in case the RF Channel Release
is not acked.
This reverts commit fc462dd59e.
libosmogsm is a new library that is distributed in the libosmocore.
Now, openbsc depends on it. This patch gets openbsc with this
change.
This patch also rewrites all include path to the new
osmocom/[gsm|core]
