- dnsmasq:
- allow listening to all interfaces again to serve DHCP leases
- disable most of the default DHCP options, keep broadcast and
netmask because when dnsmasq can infer these they are better
than breaking networking for clients -- note, they can still
be overridden from global/subnet/host scope -- and for relay
setups they need to be supplied anyway
- confd:
- drop per-interface dnsmasq, although practical for many use-cases,
having a per-subnet focused server means improved integration with
future stand-alone dhcp relay setup
- implement suggested, simplified, yang model

This patch introduces a new yang yang model for DHCP server and relay,
using dnsmasq to provide the functionality on a per-interface basis.
Available DHCP options will be queried by confd on startup and can
then be configured in a flexible manner.
The DHCP option 82 feature has been realized by patching dnsmasq
(see patches/dnsmasq/2.90/0000-relay-agent-info.patch).

Similar to the run_multiline() method, sometimes files contain more than
one line and a common read_multiline() quickly becomes useful. This is
currently only used by ietf-system for reading /etc/resolv.conf.head.
Also, fix pylint warning for missing encoding to all open() calls.

Due to #902 (which has not been root caused at this time), podman may
indicate the existance of an interface that yanger is not able to
locate in any namespace. Therefore, make sure that we verify that the
interface was actually found before trying to create the operational
data for it.
Break up the --test parameter into either:
--capture: Write system command output to a local directory for later
consumption by...
--replay: Which can replay a previous capture
Rename --wrap-commands => --cmd-prefix
Allow all host commands to be run with a prefix (e.g. `ssh
user@remotehost sudo`), such that yanger can be tested against the
current state of a remote system.
If a command wrapper _and_ a test directory is specified, the output
of all commands and files are recorded for use by a future test
execution.
Example:
1. Launch a `make run` instance and setup some config for which we
want to test yanger and cli-pretty
2. Capture the output of all commands needed to produce the data for
some YANG model:
`yanger -t /tmp/ifs -w "ixll -A ssh qtap1 sudo" ietf-interfaces`
3. Kill the instance (we do not need it any more)
4. Test cli-pretty using the captured state:
`yanger -t /tmp/ifs ietf-interfaces | cli-pretty show-interfaces
`
The yanger source grown significantly, code is disorganized, the
namespace is all over the place, etc.
Take a stab at remedying the situation by splitting out the individual
YANG models in separate Python modules, starting with ietf-system.
Basic support GRE and GRETAP tunnels both for IPv4 and IPv6.
Limited support right now, only possible to configure local
ip address and remote ip address.
With the FRR upgrade to 9.1.2, OSPF sometimes reports neighbors
without reporting the routerDesignatedId and routerDesignatedBackupId
attributes. Ensure that these attributes are available before trying
to copy them to the output.
Make show interfaces container aware. This is done by looking though
all podman containers for interfaces and looking up there info from
network namespaces on the main system / hypervisor.
Interfaces controlled by containers are clearly marked in the "show
interfaces" output, with a single gray row. Telling the user that they
belong to one or more named containers. The user can then run "show
interface name NAME" on interfaces owned by containers, which provided
some additional info, such as mac address and stat counters.
The patch also add support for printing veth peers which are owned by
containers.
Lastly, the patch also adds test cases for this functionality.

This patch adds support for setting the free form description string as
the interface alias. This can be read from /sys/class/net/*/ifalias, or
using the 'ip link show' command. The ifalias is reported by SNMP and
LLDP by default, and now also in the operational datastore.
Linux supports 250 characters in ifalias, but the IF-MIB is restricted
to 64 characters, so we add a local deviation to limit the type.

In e373398 we restored statd suport for checking for faults in yanger at
runtime. This in turn broke CLI "show interfaces" support on the little
NanoPi R2S because ethtool cannot read counters in JSON format on it.
This patch catches the subprocess exception, allowing this particular
call to ethtool to fail with empty result. The only difference from
before e373398 is that run_json_cmd() will log an error that ethtool
failed, for every interface it is called on.

FRR prints uptime different based on how long it is. Prior to this
commit yanger expected uptime to be on the format HH:MM:SS which it is
as long as it's shorter than a day. If it's longer the format changes,
this commit handles this.
The commit also adds unit test data triggering the different formats
(<day, <week, >week).
Side note:
cli-pretty could be made to represent the data on "FRR format" again,
which is perhaps more human friendly.

Fix flaky ietf-routing unit tests.
Prior to this patch, there was a unit-test race between Yanger
(sysrepo emulator) and cli-pretty, where the local system time could
change between crafting the data and printing it. This caused the CLI
output to change and the ietf-routing unit test to fail.

In "14128047e18d statd: remove nl code and improve speed" the handling
of all interfaces where moved from statd to Yanger. This means statd no
longer tracks interfaces using Netlink, but instead relies on Yanger
to recognise and list all interfaces in the system. In the midst of
this change the ignoring of "internal" interfaces where lost.
In this commit we reintroduce this logic in Yanger and add a test case
that ensures internal interfaces isn't listed.

- Enable OSPF route metrics in RIB, only defined for OSPF
- Enable 'active' route flag for RIB, same as 'selected >' in FRR
- Enable 'last-updated' route field for RIB, used for uptime
- Augment route in RIB with 'installed' flag, same as 'FIB *' in FRR
The CLI "show ip route" command has been updated accordingly. The
classic Cisco style output has been kept instead of separating the
routes into Active and Backup, as discussed previously. Because
when inspecting large route sets you want to compare same prefix
vs distance/metric to understand why a certain route is selected.

In d616623a an attempt to silence bogus return values from mctl, when
multicast snooping is disabled on a bridge. That helped get data back
for operational to produce `show interfaces` *with* a bridge and ports
but still emitted bogus log warnings.
This patch addresses that by checking 'check' on JSONDcodeError as well
before emitting any log error.

This is a major redesign of statd interface handling. The goal here is
to reduce the time it takes for statd to produce operational data for
all interfaces on larger iron. Which manifested itself most notably in
the CLI command "show interfaces".
This patch removes the netlink interface subscriptions done by the
statd c code. Instead statd now subscribes to the ietf-interfaces
base path which means it will be invoked for all interfaces.
If the user (sysrepo) has specified an explicit interface name such as
eth0, it will be extracted by statd and passed down to Yanger.
This patch also modifies Yanger to fit this new modus. No explicitly
passed interface name now means all interfaces.
Side note:
The main culprit of the slow operational interface data is the time it
takes to bootstrap python. Which prior to this patch was done for each
interface. On the HW system I'm testing this patch on, runtime is
reduced by a factor of 10.
