2016-06-18rm dup: use channel type names from libosmocoreNeels Hofmeyr2-4/+6
In gsm_lchant_name(enum gsm_chan_t), use the gsm_chan_t_names value strings from libosmocore instead of redefining the same strings. The list from libosmocore is also more complete, including CCCH and PDTCH. Add a todo comment to move to libosmocore. In consequence, libosmogsm linkage needs to be added to osmo-bsc_mgcp, mgcp_test, mgcp_transcoding_test and smpp_mirror, smpp_test. Change-Id: If65ee7c0619cbc0acb0a15045bd5a969442c93cc
2016-06-14Make random extension range configurableMax2-3/+24
Previously if subscriber was automatically created it got assigned random MSISDN number between 20000 and 49999. Make it configurable with new vty command "subscriber-create-on-demand random" and expand vty tests to check it. Change-Id: I040a1d227b0c7a1601dc7c33eccb0007941408a6 Related: OS#1658
2016-06-05Add regexp authorization policy for IMSIMax1-0/+16
* extend "auth policy" vty command with new option "regexp" * add vty command "authorized-regexp" for setting arbitrary POSIX regular expression * add basic vty test * add optional "regexp" argument to subscriber-create-on-demand vty command With those in place we can now set the regexp against which MS's IMSI will be matched. If IMSI match the regexp than MS is allowed to access the network. If subscriber is already marked as authorized in HLR than it'll be allowed regardless of IMSI matching. The same way we can decide whether to create subscribers on-demand basesd on IMSI regexp match. Similar to authorization this restriction can be overridden by manually creating subscriber via vty, ctrl interface or directly in HLR.

2016-05-25filter/nat: Fix the context for the imsi assignmentHolger Hans Peter Freyther1-0/+3
In c09f8a3b7fb94ccef41e33c32bfe2bff1ffe0e44 as part of a cleanup I accidently changed the talloc context from "con" to "bsc". The issue occurred at an earlier commit when assigning req.ctx to the "wrong" context. The allocation needs to be scoped by the struct nat_sccp_connection and not the connection from BSC to NAT. Before we have a nat_sccp_connection we scope the copied imsi to the bsc_connection and then steal it, but for the identity resp we will always have a nat_sccp_connection and can already use the right context.

2016-04-29osmo_oap_decode(): Use common argument orderingHarald Welte1-2/+2
In general, if a function generates output data like a msgb (or in this case filling an osmo_oap_message structure), the output argument precedes the source. This is what we use all over libosmo*, and it is modelled after memcpy(), where dst is the first argument, before src. Let's align osmo_oap_decode(). Intestingly, osmo_oap_encode was already correct, so the encode/decode functions used different conventions before.

2016-04-29Start to use struct osmo_auth_vector from gsm_auth_tupleHarald Welte2-4/+4
Rather than having a 'private' structure for kc, sres and rand, we now finally (with 4 years delay) use osmo_auth_vector from libosmogsm, which encapsulates authentication vectors that can be either GSM triplets or UMTS quintuples or a combination of both. gsm_auth_tuple becomes a wrapper around osmo_auth_vector, adding use_count and key_seq to it. key_seq is no longer initialized inside gprs_gsup_messages.c, as there is no CKSN / key_seq inside the message anyway. If a usre of the code needs key_seq, they need to manage it themselves.

The same goes for optional verbosity argument which is not used right now but will be handy for future debugging.

2016-04-07ctrl: Extend ctrl command to optionally handle alg+kiHolger Hans Peter Freyther1-0/+27
Extend the existing ctrl command to be able to specify the algorithm and Ki. In contrast to the VTY no size check is done. Together with the VTY this code only supports a small part of what is supported by libosmocore. The algorithm and ki are considered optional but if a valid algorithm other than "none" is passed, a KI must be passed as well. Extend the test coverage by passing the potential values. It is not verified that the KI/algorithm is stored.
2016-04-06subscr: Make db_create_subscriber fail on duplicatesHolger Hans Peter Freyther1-1/+5
The issue of db_create_subscriber updating an already existing subscr is that the same subscriber will then have two entries in the active subscribers list. In general this will break assumptions that a subscr can be compared by comparing the pointer. In the case of the VTY this was not an issue as the created subscr was immediately destroyed again but it is better to avoid this problem. Change the VTY command to find the subscriber and then call sync to have the updated time set. The side-effect is we will now have two queries for the subscriber. Once through subscr_get_by_imsi and once through db_create_subscriber. Change the db_create_subscriber to fail if a subscriber already exists, and add a testcase for this behavior and do not updated the 'updated' timestamp of an already existing subscriber. Add a testcase for this behavior. Related: OS Issue #1657
2016-04-06subscr: Add testcase creating an already created subscriberHolger Hans Peter Freyther1-0/+36

2016-03-31Fix MM Auth: zero-initialize auth tuple before first useNeels Hofmeyr2-1/+27
Make sure a new auth tuple is initialized after db_get_lastauthtuple_for_subscr() returns an error, i.e. if no tuple is present for the subscriber yet. Before this patch, the first key_seq depended on the typically uninitialized value that was present in auth tuple's key_seq upon calling auth_get_tuple_for_subscr(). The very first key_seq used for a new subscriber will now always be 0. Before, it used to be mostly 1 ("(0 + 1) % 7"), but depended on whether the key_seq was indeed initialized with 0, actually by random.
2016-03-31Fix MM Auth: disallow key_seq mismatchNeels Hofmeyr2-0/+38
In auth_get_tuple_for_subscr(), add missing condition to match incoming key_seq with stored key_seq, so that re-authentication is requested for mismatching key_seqs. Add test for this issue.
2016-03-31MM Auth: introduce AUTH_ERROR constant.Neels Hofmeyr2-2/+2

If an MM context cannot be found based on BBSGP info and a RA UPDATE REQUEST is received, try to find an MM context with an P-TMSI from which the TLLI could have been derived. This also checks, whether the routing area matches. This is similar to the old behaviour removed by the commits "sgsn: Only look at TLLIs in sgsn_mm_ctx_by_tlli" and "sgsn: Remove tlli_foreign2local", except that this will only be done for RA UPDATE REQUESTs now.

This commit adds a parameters to pass the RAID and adds missing dummy RAIDs. Note that the CI can still not be set and thus is always 0. Sponsored-by: On-Waves ehf
