* msgb: Let msgb_hexdump be more tolerantJacob Erlbeck2015-12-211-7/+39
| | | | | | | This patch makes msgb_hexdump accept out of range lXh pointers and shows info about them instead of aborting the dump entirely. Sponsored-by: On-Waves ehf
* msgb: Add msgb_resize_area and msgb_copyJacob Erlbeck2015-12-212-0/+94
| | | | | | | | | | | | | | | These functions originate from openbsc/src/gprs but are generic msgb helper functions. msgb_copy: This function allocates a new msgb, copies the data buffer of msg, and adjusts the pointers (incl. l1h-l4h) accordingly. msgb_resize_area: This resizes a sub area of the msgb data and adjusts the pointers (incl. l1h-l4h) accordingly.

* LaPDm: Refuse SUSPEND/RESUME/RECONNECT in BTS modeHarald Welte2015-12-191-0/+17
| | | | | | The primitives for SUSPEND, RESUME and RECONNECT are only permitted on the MS side of the LAPDm link, not on the BTS side. So we should check for this and reject, accordingly.
* ns: Force a defined state when sending NS RESETJacob Erlbeck2015-12-173-0/+108
| | | | | | | | | | | | | | | | | | | | | | | | | Currently the state is assumed to remain the same while the reset procedure is active. While this works correctly in general, a single unexpected BLOCK_ACK or UNBLOCK_ACK can change the state but will not stop the reset procedure. The leads to repeated RESET messages, where the corresponding RESET_ACK is ignored. This is a stable state which can only be left by manual intervention or by reception of a RESET message from the peer. This commit changes the RESET timeout handler to set the state to BLOCKED/RESET when sending the new NS RESET message. Note that this should ensure a clean restart even if the state has been screwed up. It does not fix the handling of BLOCK_ACK or UNBLOCK_ACK in abnormal cases.

* remove our internal copy of talloc, use system libtallocHarald Welte2015-12-0517-2089/+28
| | | | | | | Shipping our own private copy of talloc was a good idea in 2008, when it was not readily available on most target platforms. Today, the situation is quite different, as it is a standard library on major Linux distributions.
* stats: Add TODO comment to rate_ctrJacob Erlbeck2015-11-261-0/+3

* stats: Reorder functions in stats.cJacob Erlbeck2015-11-261-59/+61

* stats: Move statsd related code into a separate fileJacob Erlbeck2015-11-264-144/+180
| | | | | | | | | | | This commit moves the stats specific code parts into stats_statsd.c while keeping the generic parts in stats.c. The code in stats.c no longer contains references to statsd symbols. Note that the VTY code still needs to know about every stats reporter backend. Sponsored-by: On-Waves ehf
* configure: It should be --with-system-talloc, not --enable-system-tallocHarald Welte2015-11-211-8/+8

* use system-wide libtalloc with --enable-system-tallocHarald Welte2015-11-214-3/+59
| | | | | | | | | This introduces a new configure flag by which the libosmocore-internal talloc code is not compiled, but rather a system-wide libtalloc is used. When we started openbsc/libosmocore in 2008, libtalloc was not widely present on systems yet. This has changed meanwhile, and we should simply use the system-wide library

* stats: Fix not reported stat item valuesJacob Erlbeck2015-11-091-1/+3
| | | | | | | | | | | | Currently the global stat item index is being advanced in osmo_stat_item_group_handler, so that the second and further groups in the list will skip new item values. This commit moves the call to osmo_stat_item_discard_all into osmo_stats_report to a place where all groups have been processed already. Sponsored-by: On-Waves ehf
* stats: Fix handling of multiple resportersJacob Erlbeck2015-11-091-2/+2
| | | | | | | | | | | | | Currently the reporter loop is aborted, if the event would be ignored due to an insufficient max_level. Thus the reporters that happen to be stored afterwards would be skipped even if their level were sufficient. This commit replaces the conditional 'return' statement by a considtional 'continue' statement to ensure the processing of the list tail. Sponsored-by: On-Waves ehf
* stats: Send all values on reporter updateJacob Erlbeck2015-11-092-8/+26
| | | | | | | | | | | | | | | | | | | | | Currently only counter changes and new item values are being reported. This makes it cumbersome to configure reporting clients, since there is nothing like a list of all parameters. This commit changes this behaviour such that all currently existing counters and items that would be reported eventually, are passed to the reporter when it has been reconfigured or enabled. If a counter has not been incremented, 0 is sent. If a stat item value has not been added, the last item value (or the default value if there is none) is resent again. Note that this will not catch transient counters/items that will be created later on, e.g. triggered by new peers or subscribers. To just force this kind of dump on a running reporter, it is sufficient to invoke the 'enable' command in its configuration node. Sponsored-by: On-Waves ehf
* stats: Fix name prefix handlingJacob Erlbeck2015-11-091-11/+23
| | | | | | | | | | | | | | Currently the having an unset prefix leads to an abort() in the statsd reporter due to an fprintf format string error. In addition the prefix cannot be reset to its initial state (NULL) by using 'no prefix', which just sets the prefix to the empty string, causing a single leading dot to appear in front of the name. This commit changes the implemenation to consistly use NULL for the unset name prefix ('no prefix') and to handle this case correctly in the statsd reporter. Sponsored-by: On-Waves ehf

* gprs-ns/stats: When the NSVCI is updated, update the stats counterHolger Hans Peter Freyther2015-11-043-0/+13
| | | | | | | | | | | The NS object is created with an unknown identity and only after the reset procedure has progressed (completed?) we know the real ID for this peer. Before nobody has looked at the idx values (this could have been seen with the CTRL interface) but with statsd the wrong NSVCI becomes obvious. Add routines to update the idx and I don't know if the change of idx is causing any issues but we will find that out soon.

* stats/vty: Add selective show stats commandJacob Erlbeck2015-08-223-2/+33
| | | | | | | | | | | | | | | | Currently there is only the 'show stats' command which shows all counter and stat_item values. This can lead to many lines of output if there are per-subscriber rate counters. The new command added by this commit allows it to only show groups of a certain level (class_id), similar to the 'level' configuration command for stats reporter. The new command is show stats level (global|peer|subscriber) Sponsored-by: On-Waves ehf
* ns/stats: Fix class_id of "NSVC Peer Statistics" rate_ctr groupJacob Erlbeck2015-08-221-0/+1
