2019-10-08Iu: implement a user inactivity timerAlexander Couzens1-0/+1
The user inactivity timer is similiar to the Gb READY timer and reduces the resources taken by an idle UE. Change-Id: I66c2ac0350cb074aefd9a22c5121acf723f239d3

2019-09-03Implement GMM State using osmocom FSMPau Espin Pedrol2-4/+5
State machine inspired in the one from TS 24.008 4.1.3.3.1. Some state transitions are inroduced in the code but are still commented out since we lack some functionalitites or improvements in the code to handle different scenarios. Most of the logic is still outside of the FSM, but at least now the states are handled in a sane way triggered by events. Change-Id: Idecb43c10d66224d4f9ba9320825040ce6cf9a07

Implement TS 23.060 6.1.2 Mobility Management States (Iu mode) using osmocom FSM and drop old implementation. Most of the logic on each state is still kept in gprs_gmm.c, will be inserted into the FSM later. Change-Id: I4c9cf8c27194817c56e8949af0205e1cc14af317

2019-09-02Move llc->MM/SM Gb specific glue code to its own filePau Espin Pedrol1-0/+1
Now that we have RANAP/Iu handling specificities in its own file, let's have also Gb specific glue code for messages coming from llc up to MM/SM layer in its own file. This way same entry points in gprs_gmm.c are used by Gb and Iu: gsm0408_rcv_gmm() (for MM) and gsm0408_rcv_gsm() (for SM). Change-Id: Iaf57922a0970c1d03f6f1d6337d27ae3d4aaf32c
2019-09-02Move lots of Iu/ranap specific code into its own filePau Espin Pedrol1-0/+1
RANAP related functionalities were splitted among several files (gprs_gmm.c, gprs_sgsn.c and sgsn_libgtp.c). Let's move it into its own file to shrink complexity/size of existing files. It also allows to keep a lot of conditionally enabled code (BUILD_IU) and its dependencies (osmo-iuh) together. Change-Id: I549042aaff045a378de77d657cc396ee08f22f33
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

2019-05-11gprs_gmm: send Service Reject when no PDP ctxs are available.efistokl2-0/+18
Look at PDP Context Status IE: if there are any PDP contexts which are ACTIVE on MS side and there are no PDP contexts which are ACTIVE on the network side, then send Service Reject with the cause "NO PDP ACTIVATED". This forces MS to reactivate the PDP contexts. 3GPP TS 24.008 Section 4.7.13.4 Service request procedure not accepted by the network. Cause # 40.

2019-02-26gbproxy_test: Fix test expectations of gprs_ns_rcvmsg()Harald Welte2-334/+340
gprs_ns_rcvmsg() in old libosmocore returns "number of bytes transmitted by any response PDU we sent as a result of the received message", while modern libosmocore simply retunrs '0' for any successfully received message. Let's make sure any non-negative responses lead to a reproducible test output with both old and new libosmocore. Change-Id: I7a48d14aed19825b87a02ccf9ee9cbfe0853342c

libosmocore commit 797558ea1768e464f9559c5f7a4f3f4285c5de25 changed the order of NS_UNBLOCK_ACK transmission dispatching of the NS_UNBLOCK signal. Update expected output of gbproxy tests accordingly to make these tests pass again. Change-Id: Ia3df811755b1c88cf7a27a466677b24a6c32fd8e Related: OS#2388
2018-11-15use enums consistently instead of falling back to intStefan Sperling1-5/+5
The two existing enums defined in gprs_sndcp_xid.h, for protocol and data compression algorithm numbers respectively, were assigned to 'int' variables when their values were copied to other structures. This prevented the compiler from checking the enum value coverage during switch statements and also tripped up Coverity scans looking for enum value mismatch problems. So instead of copying enums to ints, make use of the enums throughout. Structures which can contain values from both enums now use a union of both, forcing us to be very explicit about which set of values we are dealing with.

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

2018-09-13gprs_gmm: introduce a GMM Attach Request FSMAlexander Couzens1-0/+1
The old GMM Attach Request handling used a recursive function which can not handle certain states and is quite complex and hard to extend. The new FSM handles such request in a FSM and can be called multiple times. Change-Id: I58b9c17be9776a03bb2a5b21e99135cfefc8c912

2018-05-01GERAN: allow GSM SRES on UMTS AKA challengeNeels Hofmeyr1-1/+1
Store the established security context type (GSM or UMTS) instead of the boolean flag is_authenticated. Provide the previous boolean query with thin sgsn_mm_ctx_is_authenticated() function. Knowing which security context was established will be necessary for OS#3224, i.e. using the proper ciphering key, which is not yet tested properly, and probably not correct at this stage. This change will make new SGSN_Tests.TC_attach_umts_aka_gsm_sres pass. Related: OS#3193 OS#3224 Change-Id: I36807bad3bc55c0030d4f09cb2c369714f24bec7

2018-03-15implement support for 3-digit MNC with leading zerosNeels Hofmeyr2-25/+16
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.

2018-02-21sgsn_test: guard against struct gprs_ra_id changingNeels Hofmeyr1-3/+3
sgsn_test initializes various struct gprs_ra_id without naming the actual members, which is vulnerable to struct member re-ordering. Name the members explicitly. An upcoming ABI change in libosmocore would cause test failures here without this patch. Change-Id: I517ed9edf77fac37d9de7a39df24c419a8a65d96

2017-11-28tests: Fix selection of python versionPau Espin Pedrol3-4/+4
According to documentation (and personal experience), AM_PATH_PYTHON selects the highest version of python, no matter if major version is different, which means if both python2 and 3 are available, 3 will be chosen an PYTHON will point to "/.../python" which is python3. Apparently, the macro cannot be easily used to pick highest python2 version. As {vty,ctrl}_test_runner.py require python2 and are incompatible with python3, let's instead rely on the system having a "python2" binary available, which is the case in most distros.
