Oliver Smith 11da4a4abd stats: send real last value if no new values come
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)

Pau Espin d9825c0a2c bts_feature: Introduce feature to confiure dyn ts as sdcch8
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.

Neels Hofmeyr ac49bda4d4 osmo_select_shutdown_request(): allow finishing pending writes on SIGTERM
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.

Pau Espin af40b0b6b9 msgb_alloc_headroom: Change size args to be uint16_t
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.

Pau Espin 09f075fad6 stat,rate_ctr: Allow setting group name and use it at report time
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.

Harald Welte c545ff6f3e socket: QoS support for all our socket init functions
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.
