38 hoursbts_feature: Introduce feature to speak to PCUHEADmasterPau Espin Pedrol1-0/+1
This feature provides the BSC with information on whether the BTS talks the IPAC_PROTO_EXT_PCU osmocom extension over the underlying IPA multiplex of the OML link. Related: SYS#5303 Change-Id: Id62421f7f5540875ac877a187757f2cf0556bd02
38 hoursipaccess: Add new osmo extension IPAC_PROTO_EXT_PCUPau Espin Pedrol1-0/+1
This new extension protocol is used to forward Osmocom PCUIF messages BSC<->BTS<->PCU. It will be sent re-using the IPA multiplex of the OML link between BSC and BTS. BTS is responsible for forwarding the message over the unix socket to the PCU. Related: SYS#5303 Change-Id: I68b04def49946b6915dbd4e476999f249751cd28

8 daysstat,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.

2021-04-09add osmo_bts_features_names: short BTS feature stringsNeels Hofmeyr1-0/+5
This will be used by osmo-bts-omldummy to parse features strings from the cmdline. Note that osmo_bts_feature_name() already exists to return the longer descriptive value_strings from osmo_bts_features_descs (_descs!). Luckily that misses the plural 'features' in the name, so that I can still add a properly named osmo_bts_features_name() function that only returns the name, matching the common pattern used in osmocom code.

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.

2021-04-06stat_item: make next_id argument name consistentOliver Smith1-3/+3
Let osmo_stat_item_get_next, osmo_stat_item_discard, osmo_stat_item_discard_all consistently refer to their next_id arg as such (and not idx or next_idx). 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.

This is only the first part which only uses the binds when doing a new SNS configuration. The outgoing add procedure will be supported in a later patch when the SNS fsm supports outgoing procedures.
