2021-09-04gprs_ns2: gprs_ns2_free_bind() should remove itself before removing nsvcsAlexander Couzens1-4/+4
When removing NSVCs before removing the bind from the SNS list, the removing NSVCs could trigger a creation of a new NSVC on the same bind ending in a while(true) loop. Change-Id: I6f497348f75fb479427d8a4c23313e33fbc62036

2021-08-23vty 'stats reset': do not reset stat_itemsNeels Hofmeyr1-8/+1
Exempt all stat_item statistics from 'stats reset'. Only reset rate_ctr statistics to zero. The rate_ctr statistics have an implicit time scale, counting occurences per time unit. For them it makes sense to reset all ratings and start from zero, for example in a test suite (e.g. our TTCN3 BSC_Tests). In contrast, stat_item statistics count number of objects or nr of specific object stati at any given time, and they do not deteriorate over time. Many stat items depend on increment/decrement to be sane. For example, in osmo-bsc, if the nr of connected BTS is 3, that does not make sense to be reset to zero. There are still 3 BTS connected, only the stat_item would suddenly reflect zero. From then on, it'd be wrong. All stat_items are by definition wrong after a 'stats reset'. - Those that depend on increment/decrement will be wrong until the program exits, and - those that are set to absolute values will be wrong up until the next value is set. That could be seconds or hours later, depending. Related: SYS#5542 Change-Id: If2134768b1076e7af189276c45f2a09a4944303e

2021-08-20stats: send real last value if no new values comeOliver Smith5-1/+15
Background: * Individual values can be added to osmo_stat_item.values at any time. * Stats are reported at a fixed interval (see vty 'stats interval'), e.g. every 10 seconds. * In order to report a new stat value, we use the maximum of all osmo_stat_item.values added since the last report. * By default, we do not send new stat values if they did not change (see vty 'config-stats' -> 'flush-period' default of 0). Fix the following bug: * If 'flush-period' is 0, and no new osmo_stat_item.values are coming in, the last value that gets reported is not necessarily the last entry in osmo_stat_item.values. * For attached reporters (statsd), it could then be that the given stat stays at the wrong value for a long stretch of time (think of several hours/days/forever). Explanation of how the test shows that it is fixed: * stats get reported (value is irrelevant) * osmo_stat_item gets a new value: 20 * osmo_stat_item gets a new value: 10 * stats get reported (value: 20, the maximum of both new values) * osmo_stat_item gets no new values * stats get reported (value: 10, this is new because of the bug fix, the real last value in osmo_stat_item, different from the 20 sent earlier, without the fix it would not send anything here and the last sent value would be 20) * osmo_stat_item gets no new values * stats get reported (nothing gets sent, since the real last value was already sent and 'flush-period' is 0) Fixes: OS#5215 Change-Id: Ibeefd0e3d1dbe4be454ff05a21df4848b2abfabe

2021-08-13gprs_ns2: add recursive anchor to protect against double freeAlexander Couzens2-5/+20
When free'ing a NSE/NSVC/BIND ensure there can't be a double free by using a free anchor in the struct. Recursive free's can happen when the NS user reacts on an event (e.g. GPRS_NS2_AFF_CAUSE_VC_FAILURE) and calls the free(). Or when the user free's a NSVC when the NSE uses SNS as configuration, the fsm tries to free it again. Change-Id: If9823aadaa936e136aa43e88cee925ddd5974841
2021-08-13gprs_ns2_sns: free the NSE if the SIZE PDU is not validAlexander Couzens1-0/+14
The SGSN fsm should be freed when becoming invalid instead of going into the unconfigured state. The unconfigured states should be only used when creating the NSE (on the SGSN side). Change-Id: Ife889091ecba4180a90743deb786767008fe863d

2021-08-13gprs_ns2_udp: don't start the NSVC fsm for SNSAlexander Couzens1-1/+3
The SNS code will always create NSVC on it's own. The only case when the SNS dialect allows dynamic NSE/NSVC is on the SGSN side when accepting dynamic NSE and receiving the first SNS SIZE. In this case the NSVC FSM must not be started yet. Prevents sending NS_ALIVE before the SNS configuration has been finished. Change-Id: I86275c99432262b3c19c1ded9a77090b74303bc8

Kill programs with SIGTERM with the new vty command, as it would happen with "systemctl stop". I've considered running the select shutdown logic too in order to ensure that pending OSMO_FD_WRITE requests are serviced. But as noted in review, it's better to ensure that the regular SIGTERM code path works as expected and call that instead of introducing an alternative code path.

2021-06-30bts_feature: Introduce feature to confiure dyn ts as sdcch8Pau Espin Pedrol2-0/+3
This feature signals support to configure Osmocom Dynamic Timeslot type as SDCCH8, on top of historically supported TCH/H and TCH/F. The idea is that when unneeded, the TS is configured as PDCH, and as soon as there's need for an SDCCH and there's none available, the TS is dynamically reconfigured to SDCCH8. Once all logical channels in the dynamic TS are released and hence becomes free, the BSC will reconfigure it to PDCH. Related: SYS#5309 Change-Id: Ifc0ca8916bd3e93e5a60a7dd7391d2588fdb5532
