2021-06-30bts_feature: Introduce feature to confiure dyn ts as sdcch8Pau Espin Pedrol1-0/+1
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

2021-06-21add Kc128 to gsm0808 Create Ciphering CommandNeels Hofmeyr2-0/+22
Prepare for A5/4 support in osmo-msc. Add new function gsm0808_create_cipher2() which takes a struct as argument instead of individual fields. This is akin to e.g. gsm0808_create_handover_request() below in the file, and allows backwards compatibly extending the argument list without needing a new function signature every time. Add struct gsm0808_cipher_mode_command, as argument list for gsm0808_create_cipher2(), with kc128 included. Encode the Kc128 IE in gsm0808_create_cipher2(). Implement gsm0808_create_cipher() by calling gsm0808_create_cipher2(). Change-Id: Ib3906085e0c6e5a496a9f755f0f786238a86ca34

2021-06-18osmo_select_shutdown_request(): allow finishing pending writes on SIGTERMNeels Hofmeyr1-0/+3
Allow telling osmo_select_main* to only service pending writes (shutdown mode). Introduce API fuctions to indicate a shutdown request, and find out whether shutdown is complete. Some osmo programs have a curious sleep of few seconds upon receiving SIGTERM. The idea presumably was to finish off pending writes before halting the program. But a sleep() on program exit is annoying, especially when there usually are no pending writes, and when osmo-bsc is launched numerous times for tests.

2021-06-13msgb_alloc_headroom: Change size args to be uint16_tPau Espin Pedrol1-2/+2
Underlaying APIs (msgb_alloc) use a uint16_t as a type, which means until now passing a value > 2^16 would succeed providing a msgb with less space than requested. Since those are static inline, there's no symbols used by apps, so we should be safe enough changing the type to be uint16_t, since change would only be applied at re-compile time.

2021-06-05stat,rate_ctr: Allow setting group name and use it at report timePau Espin Pedrol2-0/+6
This patch adds a new field "name" to the rate_ctr and osmo_stat_item_group structs, together with an API to set it. This new field allows for easy identification of specific group instances when several of them exists, rather than using a sometimes random/increasing index value. If set, this name (string) is used instead of the index by the stats reporter. The name, if set, is also printed during "show stats" VTY commands. It's up to the user or application to set up unique or meaningful names to fullfill one's needs. WARNING: this commit breaks ABI and possibly creates unexpected behavior when run with non-rebuilt apps which use the modified structs directly to get the coutners, or if use the static inline API rate_ctr_inc2(). Existing users of these structs should migrate to use new APIs introduced in follow-up commits instead of accessing the field directly.

2021-04-28socket: QoS support for all our socket init functionsHarald Welte1-0/+9
Every socket function that can be passed a 'flags' argument now supports the following two additional macros that can be or-ed in with the flags: * OSMO_SOCK_F_DSCP(x) -- specify the IP DSCP of the socket * OSMO_SOCK_F_PRIO(x) -- specify the priority of the socket The existing osmo_sock_set_{dscp,priority}() functions are useful, but you cannot call them in between the socket creation and the connect() operation when using our socket helpers. This means that the first packet sent will have the default DSCP/priority, and only later packets would have the desired values. When using the functionality introduced by this patch, we can ensure that even the very first packet of e.g. a TCP or SCTP connect() will have the correct DSCP/priority applied.

2021-04-27socket: Introduce osmo_sock_set_dscp() to set socket DSCP valueHarald Welte1-0/+2
At least on Linux, sockets have a IP_TOS socket option that can be configured to set the TOS. However, TOS (of RFC791) was replaced by the DSCP (of RFC2474) in 1998. As the DCSP bits are only the upper 6 bits of the TOS bits, let's introduce a helper to get, mask and set the DSCP values in the TOS bits.

Note that osmo_bts_feature_name() already exists to return the longer descriptive value_strings from osmo_bts_features_descs (_descs!).

2021-04-08deprecate osmo_bts_feature_name(), add osmo_bts_features_desc()Neels Hofmeyr1-1/+5
The function osmo_bts_feature_name() is ill-named for two reasons: - it returns descriptive text instead of just a string representation of the name. - The enum is named "osmo_bts_features", so the function name lacks the "s" for "features". Rationale: An upcoming patch adds a function to return just the name, properly called osmo_bts_features_name(), so deprecate the weirdly named one first.

2021-04-07stat_item: make value ids item specificOliver Smith1-4/+8
Fix counting of values missed because of FIFO overflow in osmo_stat_item_get_next(), by assigning a new item value id effectively as item->value[n + 1].id = item->value[n].id + 1, instead of increasing a global_value_id that is shared between all items and groups. With global_value_id, the count of values missed was wrong for one item, as soon as a new value was added to another item. This partially reverts b27b352e ("stats: Use a global index for stat item values") from 2015, right after stats was added to libosmocore. It was supposed to make multiple readers (reporters) possible, which could read independently from stat_item (and later added comments explain it like that). But this remained unused, stats has implemented multiple reporters by reading all stat_items once and sending the same data to all enabled reporters. The patch caused last_value_index in struct osmo_stat_item to always remain at -1. Replace this unused last_value_index with stats_next_id, so stats can store the item-specific next_id in the struct again. It appears that stats is the only direct user of osmo_stat_item, but if there are others, they can bring their own item-specific next_id: functions in stat_item.c still accept a next_id argument.

It refers to an ID (item->values[i].id), not an index (item->values[i]), and it is always the next one, never the current one. Do the same change for _index/_idx variables in stats.c, which are used as arguments to these functions. Replace rd_ with next_id_ in stats_test.c, too.
