It also makes it more difficult to see, whether get/put are balanced within a function. In addition, the functions are not named consistently (gprs_subscr_delete vs. gprs_subscr_put_and_cancel). This commit changes the semantics of gprs_subscr_delete and indirectly of gprs_subscr_put_and_cancel to not call subscr_put on their argument, but to leave that for the caller to do it explicitely. It renames gprs_subscr_put_and_cancel to gprs_subscr_cancel to reflect that change in the name, too.

In that case we might still have some cached authentication tuples we avoid another sendAuthenticationInfo request. * After a detach the cache expiry would make sure to eventually send a purgeMS to the HLR (which might be ignored). At the same time to make the cache work we will need to make sure to start and stop timers. In case we don't start we might accumulate subscribers. I am afraid that the above two benefits do not outweight the complexity of this implementation. http://cgit.osmocom.org/openbsc/commit/?id=e47d4f6d1187d453b846ea48f95ee75a… commit e47d4f6d1187d453b846ea48f95ee75a42efc23b Author: Holger Hans Peter Freyther <holger(a)moiji-mobile.com> Date: Tue Jan 20 21:14:03 2015 +0100 sgsn: Remove MM from the list before gprs_subscr_delete is called Modify sgsn_mm_ctx_free to remove the entry from the list as otherwise we might double free the context from within gprs_subscriber_delete. http://cgit.osmocom.org/openbsc/commit/?id=81ffb740f78ccdada8ece786cfab852b… commit 81ffb740f78ccdada8ece786cfab852bc10172e8 Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Fri Jan 23 11:33:51 2015 +0100 sgsn: Remove inactive LLME/MM after inactivity timeout Currently old LLMEs and MM contexts that haven't been explicitly detached or cancelled are not removed until another request with the same IMSI is made. These stale entries may accumulate over time and severely compromise the operation of the SGSN. This patch implements age based LLME expiry, when the maximum age has been reached, the corresponding MM context is cancelled. If such an MM context doesn't exist, the LLME is unassigned directly. The implementation works as follows. - llme->age_timestamp is reset on each received PTP LLC message - sgsn_llme_check_cb is invoked periodically (each 30s) - sgsn_llme_check_cb sets the age_timestamp to the current time if it has been reset - sgsn_llme_check_cb computes the age and expires the LLME if it exceeds gprs_max_time_to_idle() Ticket: OW#1364 Sponsored-by: On-Waves ehf [hfreyther: Fix typo in comment LMME -> LLME] http://cgit.osmocom.org/openbsc/commit/?id=841d95f86701b9e813402c65a7b1f88d… commit 841d95f86701b9e813402c65a7b1f88d132593fb Author: Jacob Erlbeck <jerlbeck(a)sysmocom.de> Date: Fri Jan 23 12:32:38 2015 +0100 gprs: Use a macro value to set the 'Periodic RA update timer' Currently the T3312 timer is directly set as encoded value when generating the Attach/RAU Accept messages. This patch adds GSM0408_T3312_SECS and uses it to set the information element's value.

This patch extends gsm48_tx_gmm_att_ack and gsm48_tx_gmm_ra_upd_ack to always include the IE set to the default value of T3312 (44s, see GSM 04.08, table 11.4a).

To make these values configurable in seconds and to show them, conversion functions from and to seconds are needed. This patch adds gprs_tmr_to_secs and gprs_secs_to_tmr_floor. Due to the limited number of bits used to encode GPRS timer values, only a few durations can be represented. gprs_secs_to_tmr_floor therefore always returns the timer value that represents either the exact number (if an exact representation exists) or the next lower number for that an exact representation exists.

This makes it difficult for the caller to determine, whether the the whole operation has been cancelled (currently on EBADF, ENOTSOCK, EAFNOSUPPORT, EINVAL) or whether the GSUP client will retry to connect after a timeout. This will cause gprs_gsup_client_create to destroy the GSUP client object, even if the error might be temporary. This patch changes the function to return 0 if (and only if) ipa_client_conn_open was successful or the retry timer has been started. Since the return value 0 doesn't guarantee, that a subsequent call to gprs_gsup_client_send will succeed, this shouldn't break anything.
