Harald Welte 24920e2c97 gprs_ns2_sns: refactor ns2_sns_st_size_onenter()
Let's move computing of the local IP endpoints to a separate function,
so it can not only be used when entering the SNS_SIZE state. Preparation
for SGSN-side IP-SNS.

Harald Welte a0fb37627f TODO-RELEASE: Request increasing _LAST_OSMOVTY_NODE next release
We've used up all but one "library reserved" VTY nodes at this point,
and we should definitely add some more reserved nodes in the next
libosmovty ABI version / release.

Harald Welte b9f23878bb gprs_ns2_sns: Dispatch inbound SNS-ACK to FSM
We don't really handle inbound SNS-ACK yet (as we don't originate
SNS ADD/DEL/CHGWEIGHT procedures yet).  However, the message
receive code should already dispatch those events to the FSM,
just like we do for the (equally unimplemented) handling of inbound
SNS-SIZE which is already dispatched to the FSM.

Alexander Couzens 3255668afb gprs_ns2: don't OSMO_ASSERT() while freeing NS-VC.
When freeing the NS-VC there are cases when the NSE is still alive.
This means that gprs_ns2_free_nsvc() calls  ns2_prim_status_ind(),
which in turn calls ns2_count_transfer_cap().  The latter must deal
with such a situation rather than OSMO_ASSERT()

Harald Welte 48f22b0e87 CBSP: fix encoding/decoding of keep-alive repetition period
Even though the value is only between 0..120s, they didn't encode
it 1:1 in the uint8_t, but 3GPP chose to use the same encoding
as for the warning period (which has a much larger range).

Let's fix this in our implementation.

Before this patch, osmo-cbc wanted to send 30s keep-alive repetition
period, but a spec-compliant receiver actually decoded this as 80s.

Harald Welte 3217d5187f support for stats static userspace probes via systemtap
We currently only have probes for the logging sub-system.

This patch adds two tracepoints for tracing the performance
impact of statistics reporting: stat_start and stat_done.

They can be used to trace the amount of time a libosmocore-using
application spends in reporting/exporting statistics.  This includes
both the CPU time for encoding the statistics, as well as the system
calls for sending them.

Alexander Couzens 6b9d232421 gprs_ns2: rework IP-SNS binds
Introduce a `ip-sns-bind BINDID` vty command within a `nse` vty object.
The ip-sns-bind defines the binds which will be used by the dynamic
configuration with IP-SNS.
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.

This is a behaviour change of the API and must be synchronized with
the osmo-pcu. Otherwise SNS won't work with osmo-pcu.

Pau Espin bb149ecda2 logging: gsmtap: Fill PID field for each message
It was recently discovered that PID field in gsmtap log messages was
always set to 0. Before this patch, the field was never being set.

The approach of this patch is to record the PID of process one, in
order to avoid calling getpid() syscall on each
log line to be sent. The counterpart of this optimization is that
eventual fork() calls would still keep the old incorrect value, but I
think nobody can safely assume that fork() is possible once all this
kind of infrastructure has already been configured (fork() should only
be done really at the start of the program before any osmocom foo is
initialized, or to immediatelly call exec()).
