Neels Hofmeyr 6d804b1a7e add struct bsc_subscr, separating libbsc from gsm_subscriber
In a future commit, gsm_subscriber will be replaced by vlr_subscr, and it will
not make sense to use vlr_subscr in libbsc. Thus we need a dedicated BSC
subscriber: struct bsc_subscr.

Add rf_policy arg to bsc_grace_paging_request() because the bsc_subscr will no
longer have a backpointer to gsm_network (used to be via subscr->group).

Create a separate logging filter for the new BSC subscriber. The implementation
of adjusting the filter context is added in libbsc to not introduce
bsc_subscr_get/_put() dependencies to libcommon.

During Paging Response, fetch a bsc_subscr from the mobile identity, like we do
for the gsm_subscriber. It looks like a duplication now, but will make sense
for the VLR as well as for future MSC split patches.

Naming: it was requested to not name the new struct bsc_sub, because 'sub' is
too ambiguous. At the same time it would be fine to have 'bsc_sub_' as function
prefix. Instead of struct bsc_subscriber and bsc_sub_ prefix, I decided to
match both up as struct bsc_subscr and bsc_subscr_ function prefix. It's fast
to type, relatively short, unambiguous, and the naming is consistent.

Add bsc_subscr unit test.

Add MS TIMING OFFSET (3GPP TS 48.058 § 8.4.8) and P offset (3GPP TS
45.010 § 1.2) which can be used to compute MS TO from known TA.

This will be used by osmo-bts (see

RSL MEASUREMENT RESULT.

Philipp Maier 6ee49d8416 sgsn: fix problem with leading-zero-IMSIs
When the IMSI ACL is maintained via the VTY, users may enter IMSIs
without leading zeros. Especially in test environments, where
MCC=001 and MNC=01 is common, it is likely that someone enters the
corresponding IMSI (001010000000001) without the two zeros at the
beginning.

This patch fixes the problem by sanitizing the IMSI, eventually
missing zeros in the beginning will be automatically added.

Neels Hofmeyr d3270a9c05 subscriber conn: add indicator for originating RAN
Add via_ran to gsm_subscriber_connection to indicate whether a conn is coming
in via 2G/GERAN/A-Interface or 3G/UTRAN/Iu-Interface. Prepares for Iu, but
also for libvlr to decide between GSM or UMTS Auth.

Until actual Iu support is merged to master, this indicator will aid VLR unit
testing.

At some point we may also add RAN_GERAN_IU; it's not on the agenda yet, but to
clearly distinguish the names if we want to add it, explicitly name the ones we
have RAN_GERAN_A and RAN_UTRAN_IU.

Philipp Maier e0d5caa916 silent_call: remove unfinished fuzzer interface
Remove the fuzzer interface that was partially implemented in
gsm_04_08.c and silent_call.c is causing problems when an
SMS is sent during an active silent call. The reason for this
is that gsm0408_dispatch() in gsm_04_08.c would decide to
rout all uplink traffic to silent_call_rx() in silent_call.c.
silent_call_rx() is a stub function that discards the data.

This patch removes the fuzzer interface code by placing ifdefs
around it, so that it can be re-activated by experimentators.

Neels Hofmeyr acc6e8323a ctrl_test_runner: speed up more than 10 fold by sleeping less
Similar to a recent patch in osmo-python-tests for VTY based tests, but this is
for the Ctrl tests.

The TestCtrlBase tests gave a constant sleep(2) grace period for the process to
startup. This causes tests to take minutes for no reason at all.

Add code to TestCtrlBase to try and connect right away, retrying up to three
seconds in .1 second intervals. This flies through most tests without any
sleep() at all.

Philipp Maier d015cbd65d XID: resend xid with pdp-ctx-ack messages
If a pdp context is created a xid request is sent right after
the pdp-context-ack message. The sending of the pdp-context-ack
and the xid message is triggered from the GGSN via the GTP
interface.

When the pdp-context-ack message is not received by the MS, it will
send the pdp-context-request again. A lost pdp-context-ack is resent
by the SGSN directly so that the mechanism described  above does
not work for pdp-context-ack resents.

This commit adds code to trigger the sending of xid messages also
for resent pdp-context-ack messages.

Neels Hofmeyr 27355c9c65 SGSN VTY: make missing GSUP server address+port fatal
On 'auth-policy remote', the SGSN requires GSUP server address and port. If it
was missing, the SGSN would print a VTY warning and run anyway. Make this error
more fatal: print an error (flattened a bit) to stderr and abort the program.

Move validation of the GSUP server data presence out of the VTY command itself
and into the config reading function. This way the GSUP server config can be
given anywhere, including below the auth-policy config (was required above).

Don't care about setting the auth-policy to remote with a telnet VTY, because
in that case the GSUP client won't be started anyway.

Neels Hofmeyr 058cd573d8 SGSN: Integrate support for UMTS AKA
The general infrastructure for UMTS AKA is already in place:
* GSUP with capability to send us auth_vectors that contain
  either triplets or quintuples
* mm_context that holds such auth_vectors

Add:
* capability to send UMTS AUTN in GMM AUTH REQ
* parse extended UMTS RES
* on auth response, validate expected AKA with vector and received res/sres
* add Auth Failure message to receive resync AUTS token and
  * send to HLR
  * clear out-of-sync auth tuple
  * enter new state for when we're waiting for HLR to resync and send new
    tuples so that the next Auth Request will be handled

Original first half of this patch by: Harald Welte <laforge@gnumonks.org>

Full UMTS AKA procedure including AUTS resync tested to work against OsmoHLR
with R99 USIM and Milenage algorithm.

The sgsn_test.c needs adjustment because we're checking the vector's auth_types
now.

Neels Hofmeyr a1613695d1 subscr_update_expire_lu(): fix (obscure) segfault
To be paranoid, catch a NULL subscriber and/or bts in
subscr_update_expire_lu(): print an error log and avoid segfault.
(I'm not sure this would really happen in a normal situation.)

During aggressive testing of Paging timeout, I came across this segfault in
msc_release_connection() when conn->expire_timer_stopped is set but
conn->subscr is NULL, at the subscr dereference after:

        if (conn->expire_timer_stopped)
                subscr_update_expire_lu(conn->subscr, conn->bts);

I brought this situation about by a fabricated Paging fault, i.e. in
gsm48_rx_rr_pag_resp() return 0 and don't call gsm48_handle_paging_resp() at
all. Thus conn->subscr is still NULL when expire_timer_stopped is 1.

When looking at CM Service Request handling, the conn->subscr is set before
setting expire_timer_stopped = 1, which is a saner thing to do. But without my
mad 'return 0', there is in fact no way to have a NULL subscriber there.

It looks like all other code paths already do the same, but it's not that
obvious (e.g. _gsm48_rx_mm_serv_req_sec_cb()). So rather catch this case of
NULL conn->subscr, and while at it catch NULL bts as well.

Parse the longer UMTS res from the extended Auth Response Parameter IE.
Parse the R99 Authentication Failure and AUTS in case of cause
GSM_REJECT_SYNCH_FAILURE which indicates a SQN re-sync request.

Both still end in 'not implemented' error logs, which are the places where the
upcoming VLR that supports UMTS AKA will integrate.

Depends on recently added constants in libosmocore in
