This introduces a new 'e1_input' config node with a command to be
used like:
e1_line 0 driver misdn
This allows us to have different input drivers in the future
When the remote subscriber has not responded yet we could
end up with a crash in the MNCC code. It was enough to dial
the number, then hang up and bsc_hack would end up with a
segfault due the list poisining of linux_list.
The paging response should always have a TMSI or IMSI
and we should be able to find the subscriber using that. If
no IMSI/TMSI is present and we would still accept the LU
we would access the uninitialized memory.
The compiler concludes that if (ts->type == type && ts->line && line
can be false as line is NULL and then we unconditionally access
it, make it happy by adding an extra NULL check.
now it correctly names some of the IEs like DSP/FPGA version,
and also automatically marks the UDP streams as RTP depending on
what it has seen in the RSL CONNECT TRAU message.
This parameter indicates how many of the PCH+AGCH blocks are reserved
for the AGCH and thus not used for the PCH. If we set it to 0,
we basically tell the BTS there is no AGCH - and thus it would be
impossible to send any IMMEDIATE ASSIGNMENTs.
Luckily the BS-11 and the nanoBTS don't seem to care.
So far, OpenBSC simply assumed that all BTS's configured in openbsc.cfg are
neighbors of each other. While this is true for small site installations,
it is definitely not true in most real world cases. We now have the
following new commands at the 'configure bts' level:
'neighbor-list mode (auto|manual)' for selecting the mode
'neighbor-list (add|del) arfcn <0-1024>'
for adding/deleting ARFCN in manual mode
Add a short README mentioning the svn version they apply
to, how to rebase them in the future, and what they do.
The renaming is done to add a hint on in which order to
apply them. The abis_oml patch has been updated to some
value_string changes in epan, all patches now add the new
files to the CMakeLists.txt of epan as well.
Instead of using more numbers from the proto range we will
use the 0xee and then have a mini header with our new proto
id in there. For a start rename the use types to _OLD.
The transaction layer was stopping paging requests that might or
might not have been owned by the transaction. This makes the subscr
code get stuck delivering requests. This code is mostly a band aid
and just makes sure that we will kick the queue if it is needed.
Remember if this channel got opened due a paging response and in
that case when we close it down we will call subscr_put_channel
that will try to page the subscriber again. This highlights the
lack of a good subscriber management in the MSC code.
If one paging request is timing out the others will timeout soon
as well. With the current code the next timeout would expire the
next request in the queue. We will now stop all paging requests
and then issue a next paging request. So for both paging success
and failure we will now stop all the other requests.
This is mostly a workaround, one should count on how many
BTSes we are paging and wait for all failures before we remove
the item from the queue.
Kick the queue in case the paging was timing out. No one is going
to call subscr_put_channel for us so we will do it on the subscriber.
There is also another problem with multiple BTS in the LAC and paging
timeout. We will need to remember how many BTSes we have paged.
If we have a RF failure between the paging response and the auth
success we will not inform the subscriber layer of the failed paging
and instead just 'drop' the SMS. In case we have not completed the
auth and close the channel we will now send an auth failure.
The conn might be released during the loop and then conn->bts
is a null pointer and we end up crashing. Store the gsm_network
in a local variable and access this one.
Improve the debugging possibilities and print the failed attempts
and the sms that was attempted to be delivered. this should help
with debugging the code.
