2019-08-28gtp: make echo_interval unsignedPau Espin Pedrol1-3/+3
There's no real need to use -1 to indicate echo timer as disabled, since 0 can also be used (it doesn't make sense to have a timer timeout of 0). This way code is simplified. Change-Id: I689034887188a53590eddeffda781629694eb5ed
2019-08-21vty: Introduce cs7-instance-iuPau Espin Pedrol1-0/+14
Similar to what we already have in osmo-msc. Change-Id: Iaa9e1d06dd0430848ef4f7498a3c15d13f899904
2019-08-20gprs/gprs_gmm: implement T3314. Timeout to reset MM state READY->STANDBYAlexander Couzens1-1/+1
When a MS MM state is READY its exact location is known (PCU). On Gb, T3314 (aka TS 23.060 "READY timer") sets the MM state from READY to STANDBY, where only the RA is known. Introduce a second set of timer variables, because state timer can run while another packet state timer is timing out. Related: OS#1941 Change-Id: I4ce23ebe50d141076c20c9c56990b7103cd25e55

2019-06-13sgsn: Have authentication required on by defaultPau Espin Pedrol1-17/+5
Previous commit introduced command "authentication (optional|required)", which is only meaningful if auth-policy is remote. Upon adding the cmd, it changed the default logic for remote policy to not require authentication, which broke TTCN3 tests because sgsn no longer tries to authenticate the users. Since it's actually good to enable authentication by default where possible, let's enable it by default when on auth-policy remote. In order to do so, let's simply not care about the value of variable require_authentication if auth_policy is not REMOTE. As a result, we drop parts of the previous patch and remove unneeded checks (which are only partially useful based on order of commands during VTY read). Fixes: 794f446a284ed1ac6d31eb79a8f4c874d66fc34e Change-Id: Ic707a95af178b44f08809df3d3bc8354bf34273c
2019-06-06osmo-sgsn: add VTY parameter to toggle authenticationVadim Yanitskiy1-1/+36
It may be useful to have 'remote' authorization policy, but do not require authentication in GERAN at the same time, e.g. in combination with 'subscriber-create-on-demand' feature of OsmoHLR. This change introduces a new VTY parameter similar to the one that we already have in OsmoMSC: authentication (optional|required) Please note that 'required' only applies if 'auth-policy' is 'remote'.

2018-12-20make gsup ipa name configurable in osmo-sgsn.cfgStefan Sperling1-0/+22
Add a 'gsup ipa-name' VTY command which overrides the default IPA name used by the SGSN on the GSUP link towards the HLR. This is required for GSUP routing in multi-SGSN networks. The 'gsup ipa-name' option can only be set via the config file because changing the IPA name at run-time conflicts with active GSUP connections and routes configured in the HLR. The osmo-sgsn program must be restarted if its IPA name needs to change. Related: OS#3356 Change-Id: Ib2f65fed9f56b9718e8a9647e3f01dce69870c1f

2018-10-30Remove local libgsupclient; Use libosmo-gsup-client from osmo-hlrHarald Welte1-1/+1
osmo-hlr has recently (as of Change-Id Iad227bb477d64da30dd6bfbbe1bd0c0a55be9474) a working shared library implementation of libosmo-gsup-client. We can remove the local implementation in osmo-sgsn and use the system-installed shared library instead. Change-Id: I6f542945403cf2e3ddac419186b09ec0e2d43b69

2018-09-24vty: fix doc str for 'reset sgsn state'Neels Hofmeyr1-1/+5
Document all keywords of the 'reset sgsn state' command: set the same doc string for all three. Also fixes the build after libosmocore I1f18e0e41da4772d092d71261b9e489dc1598923, which resulted in HIDDEN commands coming up in the VTY reference dumping. Note that libosmocore I92c3c66ff69c186234276c64478d6342e061d25e will again remove this breakage by omitting hidden commands. Change-Id: I8b6e8615e409266910f2f76a10ced9ab33e4de91

2018-07-13osmo-sgsn: ping GGSN periodically and check for restart counterPau Espin Pedrol1-0/+25
Before this commit, echo req/rsp logic was implemented in libgtp but never used in osmo-sgsn. This commit adds a timer which periodically sends a GTP ECHO Request to every GGSN if there's at least one pdpd context associated with it. This way by checking the restart counter in the ECHO Reply it can be known if the GGSN was restarted. In this case, logic already present in osmo-sgsn will terminate all pdp contexts associated with that GGSN. Change-Id: I9d714726785407859f26bbef052cd0efc28e8dae
2018-03-15implement support for 3-digit MNC with leading zerosNeels Hofmeyr1-5/+3
Add 3-digit flags and use the new RAI and LAI API from libosmocore throughout the code base to be able to handle an MNC < 100 that has three digits (leading zeros). Note that in gbproxy_test.ok, 0-0 changes to 000-000 instead of 000-00, because the parsed ra buffer is 000000 which results in 000-000, while 00f000 would result in 000-00. IOW this is expected.

2018-03-06vty: absorb command explanations from osmo-gsm-manualsNeels Hofmeyr1-15/+38
The osmo-gsm-manuals/vty/sgsn_vty_additions.xml contained many command explanations that are redundant with the VTY online doc. Some however are more verbose / easier to understand. Absorb these into the online VTY doc here. This matches the removal in osmo-gsm-manuals change-id I71863e5056ad369d2055e9882a52a00fa999ab04. Change-Id: I35984014424412e91437b7ed71576aef3819cb1e
