* Move msgb_push helpers to public headerMax2018-11-193-39/+25
| | | | | | | | | | The msgb_wrap_with_TL() is generally useful so it make sense to make it public to facilitate code re-use. Other helpers can be implemented as trivial wrappers over existing tlv.h functions. Update headers and code accordingly. Change-Id: I37e91d031fba28cf1c6735b8069b0265746f55e6

* make 'show rate-counters' show group indexStefan Sperling2018-10-291-1/+1
| | | | | | | | | | | | | | Show each rate counter group's index in the output of the 'show rate-counters' command, to provide some way of telling apart distinct instances of the same rate counter group. This is not a very user-friendly UI because these indices are generated internally by libosmocore and/or applications, so users cannot easily assign meaning to these indices. However, the current rate counter implementation doesn't allow for more. Change-Id: Ieb151239407e4b2f8859fefec8d0670f5ddf908a Related: OS#3674
* stop printing group description in vty_out_rate_ctr_group_fmt()Stefan Sperling2018-10-292-3/+1
| | | | | | | | | | | | | | When vty_out_rate_ctr_group_fmt() prints the description of a counter group, it assumes this description should appear at the beginning of a line. However, the caller might be printing counters in an indented context. So just let the caller worry about printing the group title if necessary (there is currently only one known caller, which is updated in this commit). Note that printing of the group title was an undocumented feature. Change-Id: I2c55cb54e8b7a7c8c6cf72f22287083767ed0201 Related: OS#2660

* stats_statsd: Send all stat_items as gaugesDaniel Willmann2018-10-241-11/+8
| | | | | | | | | | | | | When sending a statsd metric we need to specify a type which can be a "g"auge, "c"ounter, "t"imer, "h"istogram, and "m"eter. We used to just pass the stat_item unit into this field, but that is the unit of the metric (Seconds for a timer, % for utilization, ...). Change the type field so stat_items are sent as "g"auges. Note that negative values don't seem to be supported by statsd. Change-Id: Ia16270d36c9a14521594de4b99a48c83e4ac07d4

* gsm0808: allow decoding of zero length speech codec lists.Philipp Maier2018-10-162-10/+23
| | | | | | | | | | | | | | | | | | | | | 3GPP_TS_48.008, 3.2.2.103 Speech Codec List states the following: "The length indicator (octet 2) is a binary number indicating the absolute length of the contents after the length indicator. The length depends on the number and type of Speech Codec Elements to be included. The minimum length of one Speech Codec Element is 1 octet and the maximum length is 3 octets. The maximum number of Speech Codec Elements within the Speech Codec List is not defined." This clearly refers only to the length of a single speech codec element but not on the overall list. So speech codec lists with length 0 are indeed permitted by the spec. - Remove the assertion that checks on zero length speech codec lists.

* vty logging: fix crash when missing 'logging enable'Neels Hofmeyr2018-10-012-0/+11
| | | | | | | | | | | | | | | We must explicitly check the return value of osmo_log_vty2tgt(), or may run into a segfault. I wasn't aware of this and introduced numerous such cases in I36f17c131cc70ce5a1aef62fd9693097de230cd4. Reproduce: on the VTY, do not issue 'logging enable', invoke 'logging level force-all LEVEL' first. Show in logging_vty_test.vty that this situation is now again amended by telling the user that logging was not enabled. Related: OS#3611 Change-Id: Id11702d1801d6654ca5e5a51b597a0d802e2e8dd

* Add new osmo-config-merge utilityHarald Welte2018-09-255-2/+275
| | | | | | | | | | | | | | | | | | | | | | | This utility allows you to merge an incremental config "patch" into an osmocom-style config file. The patch file follows the same syntax as the original config file. It works by appending the leaf nodes of the patch file to the respective nodes of the input config file. This process allows configuration file changes/updates to be performed in a more stable/reliable way than by means of [unified] diff files, as they break every time the context lines break. osmo-config-merge doesn't suffer from this problem, as it understands the tree-like nature of VTY config files. NITE: This only works with configuration files that have proper indenting, i.e. every level in the hierarchy must be indented excatly one character, not multiple.
