Add an option to disable printing the timestamp. This is useful to not
have duplicate timestamps, when stderr is piped into a logging system
that adds timestamps on its own. For example with systemd's journald:
$ journalctl -u open5gs-smfd
Apr 10 13:25:18 hostname open5gs-smfd[1582]: 04/10 13:25:18.274: [app] INFO: Configuration: '/etc/open5gs/smf.yaml' (../lib/app/ogs-init.c:130)
Configuration change:
```
<OLD Format>
logger:
file: /var/log/open5gs/smf.log
<NEW Format>
logger:
file:
path: /var/log/open5gs/smf.log
```
Example config, to have no timestamps on stderr:
```
logger:
default:
timestamp: false
file:
path: /var/log/open5gs/smf.log
timestamp: true
```
Allow network operators to omit the time zone in the 4G EMM Information
and 5G Configuration Update. This is useful for better compatibility
with some UEs.
The parameter is optional according to:
* 4G: 3GPP TS 24.301 Table 8.2.13.1
* 5G: 3GPP TS 24.501 Table 8.2.19.1.1
The subscriptions to NRF should be tied to the number of NF's and number
of services per NF that we support, instead of number of UE's.
This decreases memory usage of each NF slightly, depending on the
configuration.
o Generate the private key as below.
$ openssl genpkey -algorithm X25519 -out /etc/open5gs/hnet/curve25519-1.key
$ openssl ecparam -name prime256v1 -genkey -conv_form compressed -out /etc/open5gs/hnet/secp256r1-2.key
o The private and public keys can be viewed with the command.
The public key is used when creating the SIM.
$ openssl pkey -in /etc/open5gs/hnet/curve25519-1.key -text
$ openssl ec -in /etc/open5gs/hnet/secp256r1-2.key -conv_form compressed -text
In ausf/udm.yaml

* [HSS] Enable Change Streams
* Enable Events and Timers in HSS
* Integrate change streams in dbi

* Initial metrics support based on Prometheus
This commit introduces initial support for metrics in open5gs.
The metrics code is added as libogsmetrics (lib/metrics/), with a well
defined opaque API to manage different types of metrics, allowing for
different implementations for different technologies to scrap the
metrics (placed as lib/metrics/<impl>/. The implementation is right now
selected at build time, in order to be able to opt-out the related dependencies
for users not interested in the features. 2 implementations are already
provided in this commit to start with:
* void: Default implementation. Empty stubs, acts as a NOOP.
* prometheus: open5gs processes become Prometheus servers, offering
states through an http server to the Prometheus scrappers. Relies on
libprom (prometheus-client-ci [1] project) to track the metrics and format
them during export, and libmicrohttpd to make the export possible through
HTTP.
[1] https://github.com/digitalocean/prometheus-client-c
The prometheus-client-c is not well maintained nowadays in upstream, and
furthermore it uses a quite peculiar mixture of build systems (autolib
on the main dir, cmake for libprom in a subdir). This makes it difficult
to have it widely available in distros, and difficult to find it if it
is installed in the system. Hence, the best is to include it as a
meson subproject like we already do for freeDiameter. An open5gs fork is
requried in order to have an extra patch adding a top-level
CMakeList.txt in order to be able to includ eit from open5gs's meson
build. Furthermore, this allows adding bugfixes to the subproject if any
are found in the future.
* [SMF] Initial metrics support
* [SMF] Add metrics at gtp_node level
* docs: Add tutorial documenting metrics with Prometheus
The configuration has changed. PFCP node rr=0 is removed as shown below.
sgwc:
pfcp
rr: 0 <-- Removed
Introduced a new configuration method for SMF/SGW-C
parameter:
no_pfcp_rr_select: true
By default, PFCP round robin selection is allowed.
The above parameters prohibit selecting PFCP in a round robin manner.
If parameter.ignore_requsted_nssai is true,
AMF will ignore the UE Requested NSSAI and create an allowed-NSSAI
based on the Default S-NSSAI in the Subscription DB.
* AAR Media-Sub-Component modification for more UEs support
* Introduce parameter for legacy support for pre-release LTE 11 devices to do calling
IE (IPV4-local-addr field ) is not supported on
the LTE pre release-11 UEs. In order for the call
to work the local address in packet filter must
be replaced by any.
Parameter: no_ipv4v6_local_addr_in_packet_filter
