Alexander Couzens 1c7869e52f gprs/sgsn: rename sgsn_mm_ctx_alloc() -> sgsn_mm_ctx_alloc_gb()
Postfix the ran type to clarify the purpose.
Because of the new support of the Iu ran type, there are 2 functions to allocate a mm ctx.
For Iu it's sgsn_mm_ctx_alloc_iu(). For gb it should be named in the same way.

Philipp Maier 9bf7dcba11 sndcp: Allow empty SNDCP-XID indications
In some rare cases the modem might send a xid indication that does
not contain anything except the version number field. The sgsn
ignors such SNDCP-XID indications by stripping the entire field
from the response. We found a modem in the wild that started to
act problematic when the empty SNDCP-XID was missing in the
response. This patch changes the XID negotiation behaviour in
a way that if a modem should send empty SNDCP-XID indications,
the reply will also contain an empty SNDCP-XID indication. Apart
from that the SNDCP-XID version number is now parsed and echoed
in the response. This ensures that we always reply with the version
number that the modem expects. (The version was 0 in all cases we
observed so far)

messages from experr.

Todo: we're using a "Library" logging category, which is not really what the
library category was intended for. Instead, the OAP client should probably be
given a logging category like DVLR or DGPRS in its initialization API.

Neels Hofmeyr 325bdfb617 oap: rename public API from oap_ to oap_client_
Mainly to differentiate the OAP messaging API (osmo_oap_ in libosmocore) from
the OAP client.

This is in preparation for moving the oap client to libcommon, which is in turn
preparation for libvlr. Add the osmo_ prefix, as all public Osmocom API should
have. We also have OAP messages code in libosmocore, so clarify by naming this
osmo_oap_client, and by also renaming the oap_test to oap_client_test. This
reshuffling will allow an easy move of OAP to libosmocore if we should want to
do that. A number of patches will follow up on this.

Neels Hofmeyr 21edaef1a5 Move timezone settings up to network level
Time zone used to be configurable per-BTS. In the upcoming MSC-split, no BTS
structures will be available on the MSC level. To simplify, drop the ability to
manage several time zones in a core network and place the time zone config on
the network VTY level, i.e. in gsm_network. If we are going to re-add fine
grained time zone settings, it should probably be tied to the LAC.

Adjust time zone VTY config code (to be moved to libcommon-cs in subsequent commit).

Adjust time zone Ctrl Interface code.

Neels Hofmeyr 0303b388e8 reinvent connection_for_subscr() and move to libmsc
Implement connection_for_subscr() from a completely different angle: instead of
looking up lchans in bts structs, look up the subscriber in the global list of
gsm_subscriber_connection. static lchan_find() is thus obsoleted.

All callers of connection_for_subscr() live in libmsc, so move to libmsc.

The move and edit are done in a single commit since the old and new
implementation have nothing in common.

Future: osmo-cscn will use this, without bts being present.

Remove implementation of connection_for_subscr() from channel_test.c -- it is
possible that the abort() in there was intended for a regression test, but
actually it seems the implementation was merely added for linking reasons, and
the abort() added to guard against the NULL return value: no comment nor the
commit log indicate that the abort() is test critical; the addition was the
only change in channel_test.c for that commit; at the same time a
connection_for_subscr() call was added in libmsc.

for the next RP reference.

The only very thin function in gsm_04_11_helper.c thus becomes obsolete: drop

Neels Hofmeyr a60c3d1958 move to libcommon-cs: net init 3: actual move
Reincarnate gsm_network_init() as the parts not specific to libbsc.
Move from bsc_network_init() those bits that are not BSC specific (and useful
for upcoming osmo-cscn).

Add libcommon-cs to all linkages that use gsm_network_init().

Note: the only requirement to allow linking gsm_network_init() without libbsc
is to keep the call to gsm_net_update_ctype() out of libcommon-cs. The other items
are kept out of libcommon-cs because it makes sense semantically. But the separation
is not strong in that the BSC specific data members are of course still
omnipresent in struct gsm_network. If bsc_network_init() is not called, these
are not initialized properly -- for now no users of uninitialized members
exist.

So this is just a first step towards a sensible split of the BSC and MSC
gsm_network structs. The long term aim should be to have entirely separate
structs with some common general items.

bsc_network_init() is more fit to live in a BSC specific header, move it to new
common_bsc.h. It will probably also absorb the BSC-specific part of gsm_network
in the future.

Adjust header includes across the board. Particularly, fix abis_nm.h by
explicitly including gsm_data.h: it so far relied on other headers to do that,
which now is no longer always given.

Add option to TextTestRunner that shows print output on stdout.
It's better to see everything in our jenkins runs and not hide test output.

Neels Hofmeyr 7c3822d5a1 vty_test_runner.py: fix nat_msc_test(): socket attach: reduce timeout, retry
In nat_msc_test(), upon socket timeout, retry up to six times. Reduce the
timeout between retries. This should get rid of sporadic test failures that
we've been seeing a lot on jenkins lately.

Raise an exception upon unexpected vty response.

Print more detail to stdout. Since we would actually want as much output as we
can get in a test suite, remove the 'if (verbose)' and just always print the
connection source. unittest is keeping all stdout silent by default anyway.
