To get an overview of what base stations are present in a network, particularly
with many base stations being present, it is particularly useful to get a list
of connected base stations instead of just output of received replies.
Keep a sorted list of known base stations, which time out after 10 seconds.
Print additions and removals, and total amount of replies received. On each
change, print the entire list.
Output a running total of replies received, to provide comfort to the reader
that something is still happening, and to confirm that the shown listing is
still up-to-date (updated on the same line by means of '\r').

libosmo-sccp is the old sccp-lite-focused SCCP implementation that we
used before libosmo-sigtran was created. The new osmo-bsc in this
repository is using libosmo-sigtran and shouldn't be using parts of

We only keep it around in configure.ac and Makefile.am for osmo-bsc_nat,
which is not even built in this repository anymore (or 'again yet'?)

Properly match up any A5/N with the MSC's list of permitted algos.
Properly set the reject cause in case of mismatching algorithm choices.
Actually allow choosing A5/1 thru 3 as configured on the VTY, by passing
a5_encryption through to gsm0808_cipher_mode() (instead of a hardcoded 1).
Properly handle failure rc of gsm0808_cipher_mode() by sending a reject
message.
Cosmetically clarify which GSM0808_IE_ENCRYPTION_INFORMATION bits mean what by
means of local variables; add some comments on expected encryption formats; add
comment that the BSC should be able to have more than one a5_encryption.

Our T3113 timer default of 60s was set early in the development of
OpenBSC, where we didn't really know what values to use and used
excessively large/safe values. Paging the same MS for 60 seconds (even
if there's no paging response) will however create a lot of PCH load for
no good reason.
It seems there's no clear guidance as to what the value should be. Other
implementations use something in the order of 10 seconds (OpenBTS,
yateBTS), which seems more realistic. THe Siemens BS-11 has a default of
5 seconds.
Let's be conservative and go to 10s as a default, which is already 6
times less potential PCH usage than our default so far...

Counting the number of T3113 expirations (one per subscriber per BTS)
vs the number of paging attempts (Bsc global) is a ueseless figure,
as you cannot relate each other.
We count on the BSC level:
* how many PAGING we received from the MSC (total)
* how many of those were for cells/LACs we don't serve
* how many of those resulted in PAGING RESPONSE
We count on the BTS leve:
* how many PAGING CMD we sent to the BTS (total)
* how many of those we ignored as we were already paging
* how many of those resulted in PAGING RESPONSE
* how many were expired due to T3113 expiring

The BSSMAP reset causes the paging requests to be flushed. When
this happens right after startup then calling paging_flush_bts()
may be called when the list bts->paging.pending_requests is not
yet initalized, which causes a segfault.
Call paging_init_if_needed() to be sure that the list is
inizalized (like the other functions also do)
Change-Id: I42ddbfdec6f9d74d858ad13cc38b5b64061d08dc
Initialize the llist head gsm_bts->paging.pending_requests at the time gsm_bts
is allocated, not only at paging_init_if_needed().
The gsm_bts->paging sub-struct is invalid as long as gsm_bts->paging.bts
doesn't point back to bts. Hence the recently added iteration of
gsm_bts->paging.pending_requests should have checked whether bts is NULL. The
llist_head pending_requests is not initialized unless paging_init_if_needed()
has been called (and paging.bts is hence set). However, this fix is a safer way
to prevent errors like this in general.

The call-back was needed inside the NITB to determine which part (CC,
SMS, ...) had triggered a given paging. A pure BSC doesn't need that

all callers use it with that type.

This timer is started when a channel is allocated with an IMMEDIATE
ASSIGNMENT message. It is stopped when the MS has correctly seized the
channel. Ever since the early days of development we were using a very
long timeout to be on the safe side. However, in production networks
this is a terrible waste of resources, as we will occupy 10s worth
of air-time on one of our channels for each RACH request we receive.
The only scenarios where you might need something absurdly high as 10s
would be if you have 8s of RTT between your BTS and the BSC.

This is left over from the OsmoNITB days. We're defining and allocating
these MSC counters, but never actually using them. This also means that

users that such counters could be used in OsmoBSC.
Let's remove them. They are in OsmoMSC, but not OsmoBSC.
