and bsc_mgcp. This means only osmo-sgsn is missing, which currently
has no option parsing at all.

[GPRS NS] Fix memory leak in gprs_ns_sendmsg() error path
...
When gprs_ns_sendmsg() succeeds in sending the message, we free()d the
msgb after transmitting it on the socket. However, if the NS-VC is
blocked or some other error condition exists, we returned an error
code but didn't free the msgb.
This resulted in an error leak which is now being addressed.

chan_alloc: Change Channel Release to release SAPIs, then the channel
...
Currently every SAPI release indication will trigger the channel. It
was possible that we had SAPI=3 and SAPI=0 allocated and we tried to
release the channel by sending a RF Channel Release, the BTS answered
with a RF Channel Release ACK but also sent the SAPI Release Indication
which triggered a channel release here. So it was possible that we
would have released a newly allocated channel because of the SAPI
release of the old connection.
This code now works by releasing all SAPIs from highest to lowest,
then sending a SACH Deactivate and finally releasing the channel. This
approach is in use on the on-waves/bsc-master.

...
This code compares the UDP sequence numbers of two RTP messages
and guesses if packets are missing. It is guessing in two ways:
1.) by default the sequence number is 0, so on the first
value we ignore the jump... we might ignore a real issue
in case of a wrap around which is easily possible as the
sequence should be a random number.
2.) the UDP stream might have been reordered on the network
and we would see the jump...
In any case these two shortcomings are acceptable for the feature
that is meant to provide some basic analysis..
