2017-03-05sgsn: fix problem with leading-zero-IMSIsPhilipp Maier1-2/+11
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. Change-Id: I56ba0da61978bbdce71d0e320166c52b20b42517

2017-02-27XID: resend xid with pdp-ctx-ack messagesPhilipp Maier1-1/+15
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. Change-Id: Ice66790803154310a61a70a54be76cec539c97a7
2017-02-27SGSN VTY: make missing GSUP server address+port fatalNeels Hofmeyr2-12/+10
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. Change-Id: I4d8db910c32abd8579d3c9b9f0b2cb3a9a6dfe4c
2017-02-27SGSN: Integrate support for UMTS AKANeels Hofmeyr3-29/+198
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.

Since ce9fec3e896571835ac5bfd2980d6836f2b29f0d libosmocore ignores parameters to log_vty_command_* functions. Hence parameter of logging_vty_add_cmds() is ignored too. As we depend on much later libosmocore version anyway, we can simplify code somewhat by removing parameters which will be ignored anyway. Change-Id: I62f752fd88f1d8fefa563648f9864c7c31f87991

2017-02-01sgsn: Fix deeply flawed copying logic for PDP context activationHolger Hans Peter Freyther1-3/+9
It is one of these changes that should have never worked but did for a long time. Only recently a corrupted GTP message was seen. The code in ccd2312d10e14747e8a4d26d8f72b052ffcfc282 tried to solve the right problem but was deeply flawed. * Make the code operate on the copied message and not the original one that is deleted by the underlaying layers on return * Add an out variable to determine if the msgb should be deleted and assume that by default it will be deleted.

in gprs_gmm.c:gsm48_rx_gmm_ra_upd_req the variable reject_cause is not initalized, which is ok, since it gets initalized before the jump into the "rejected" path.

2017-01-15gprs subscr: fix: intended strcmp(), but is strcpy()Neels Hofmeyr1-5/+3
The code checked 'if (strcpy(..) != 0)' which is always true and thus always copied twice -- luckily we want to copy anyway and so this is not an actual functional failure. We could correct to strcmp, but instead of iterating to compare, we might as well copy right away. Change-Id: I0ea035bd478f7022ed65e9e84d8aaf5e423309b7

2016-12-23sndcp: Allow empty SNDCP-XID indicationsPhilipp2-32/+47
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) Change-Id: I097a770cb4907418f53e620a051ebb8cd110c5f2 Related: OS#1794

2016-12-13oap: rename public API from oap_ to oap_client_Neels Hofmeyr2-13/+15
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.

(Id974c7be158e4d60421a98110f5c807aefd31119) Todo: we're using a "Library" logging category, which is not really what the library category was intended for.

2016-11-28IuPS: properly update ra_id on GMM Attach RequestNeels Hofmeyr1-4/+2
For new MM contexts, the ra_id was correctly obtained from the ue_ctx, but in case an MM ctx is re-used and the ra_id changed, the new ra_id was not copied to the MM context; instead, the ra_id was overwritten with uninitialized data. Always initialize the local ra_id variable from the ue_ctx->ra_id for Iu connections; it is used further below to update the ctx->ra_id. For the case of a brand new Iu MM ctx, the ctx->ra_id then gets initialized a second time. We could technically drop the init in sgsn_mm_ctx_alloc_iu(), but it doesn't hurt either way.

2016-11-27sndcp: fixup for coverity scan defect CID 149097Philipp2-0/+2
Coverity scan detects a Null pointer deref (FORWARD_NULL) in gprs_sndcp_comp.c: 67 in gprs_sndcp_comp_create(). The reason for this is that gprs_sndcp_dcomp_init() and also gprs_sndcp_pcomp_init() rely on the comp_entity->algo algo flag. If the program logic is correct a null pointer deref should never occur. This commit adds OSMO_ASSERT() statements to ensure a null pointer deref is catched if if the ...comp_init() functions are used with incorrect parameters.
