This is to workaround #807. To test automatic router id selection
a new test is required, which sets interfaces and activate ospf in
separete NETCONF/RESTCONF query.
Initially done as a workaround for the MACVLAN create/remove race. But
even though the old version of this test now works, this refactor
provides better test step descriptions, making it easier to follow for
anyone looking to manually verify the functionality.
This is a specialized namespace, containing two ports,
which (hopefully) acts as completely transparent "bump-on-the-wire"
bridge.
Useful in scenarios where you want to test what happens when the flow
of packets between two nodes is disrupted. E.g., for testing fail-over
behavior in dynamic routing protocols, L2 redundancy, VRRP etc.
Now that we're using the `passthru` mode of MACVLANs, it seems we can
rely on the parent interface's promiscuity going down to 0 as an
indication that the kernel has completed the removal of the interface,
and will accept the creation of a new one.
When used as a context manager, __exit__ will be called even though
__enter__ might throw an exception half way through. So there is no
guarantee that the instance is on the cleanup list when we get to
stop().
This mode let's us receive all packets from the parent device, which
is automatically set in promiscuous mode, and let's the MACVLAN
transmit packets with any SA, which we need to implement a TPMR (or a
bridge or anything else we might dream up)
This is needed to create namespaces with MACVLANs from different
parent interfaces. The first consumer will be a Two-Port Mac
Relay (TPMR), so that we can control the flow of packets between two
nodes.
Story time:
In the days of yore, we generated PCAPs using tcpdump, which will
flush any buffered packets to its output file on reception of
SIGUSR2. Therefore we sent a USR2 before terminating the capture.
At some point, we switched over to use tshark to capture packets for
us, but the SIGUSR2 sayed in place.
It turns out, tshark will just die on USR2, abandoning the dumpcap
child it has created, which means the enclosing network namespace
can't be properly torn down.
Therefore:
Remove skip sending USR2 and just send TERM directly.

Previously, when the `proto://path` format of `bootfile` was used, the

Not the most obvious patch, but let me explain -- there will always be a

really need to add a deviation 'not-supported', for usability, however,
it may be useful since the deviation helps cut out that tree completely.

This patch changes the way Infix DHCP and ZerocConf clients set their
routes in the system. Instead of setting them directly in the kernel
we ask FRR staticd to set them for us.
The reason for this change is to be able to override routes from these
protocols with locally set static routes. The routes are now set with
a distance of 5 and 254, respectively, while static routes by default
have a distance of 1. In contrast, kernel routes are always treated
by Frr as distance 0, i.e., they are preferred over static routes.
Finally, this patch drops the use of Linux legacy interface aliases, or
colon interfaces, in an effort to reduce confusion for end users. This
may give some odd results if using older tools like ifconfig, so we
recommend using 'show interfaces' or 'ipb a' instead.

is not used to bootstrap the Infix. Instead, /cfg/startup-config.cfg is
used and loaded directly to the running datastore.
For some use-cases when operating directly on sysrepo this causes a lot
of confusion because startup == factory ds until any user calls the CLI
command `copy running-config startup-confg`.
This patch fixes this initial "glitch" by loading the starup datastore
at boot on successful loading of startup-config to unning.
To prevent any unintentional "auto-save" of, e.g., failure-config to
startup-config, we make confd aware of this "sync" operation during
bootstap.

This is basically a functionally revert of:
435c5ca9 statd: allow ethtool --json to fail without breaking operational ds
Having a fail flag that hides all yanger faults is too big of a

"ethtool --json" it should be handled gracefully by yanger. Perhaps by
catching the error and returning an empty dataset for that node.

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.

when migrate configs the yang data produced was this:
"infix-meta:meta": {

Today Infix only support OSPFv2 and Static routes, this hides all other

In 0edc2d5 and afbe5ca, just prior to v24.06.0-rc1, support for deleting
containers in the background was added. However, this also broke support
for upgrading containers.
In afbe5ca the start script for containers was renamed from NAME.sh to
S01-NAME.sh, but the container wrapper script's upgrade command was not
updated. Neither was the cleanup and post-hook callbacks in confd! So
when a container had been added to the system, the cleanup callback just
simply deleted the script, preventing it from being recreated at ugprade
This patch fixes the container identification code and also refactors
the execd code to ensure that kill scripts (for deleting in background)
and start scripts are run in the proper order *and* ensuring that execd
also does not accidentally remove the container start script.
Some cosmetic changes to the output at upgrade have also been added.

Now that we have a unified timeout value that all front-ends should
honor, make sure to do so when loading startup-config and
failure-config during boot.
This fixes an issue where the system would fallback to failure-config
even though a legitimate startup-config was available, but took more
than 10s to apply.
While sysrepo's architecture places the responsibility of choosing a
timeout on each front-end, we want to control it centrally since the
majority of the time is spend actually applying the config to the
system - which is front-end agnostic.
Therefore, create a single definition of the timeout, which can be
included by all front-ends.
With the recent changes in Infix v24.08 to tighten up permissions, a

To support testing, the test-config.cfg file has been introduced in Infix.
Additionally, a "test mode" for the running image is required for this

Basically the test-config will only be loaded when the device is in test mode,
which is determined by the presence of the /mnt/aux/test-mode file.
However, placing this file via the Qeneth system proved to be
inconvenient in the test environment. Therefore, it the entire image is
built in test mode, with the 'test-mode' file preloaded onto the disk
image (specifically in the auxiliary partition).
To support this, a new variable, (bool) DISK_IMAGE_TEST_MODE, has been

enabled: the image will be built in the test mode;
disabled: the image will be built in the standard mode.

configuration specifically for testing purposes needs to be generated
within an image. This test-config should always be generated

both the device is operational and that the user can connect to the LAN
port.
The WAN LED is given a "wan-up" input condition, with the intention of
turning it on (green) when the device has acquired a DHCP address.
The failure modes, which in many ways is the essence of Infix signaling,
are fail-safe and panic, triggered by loading failure-config, or failing
to loadd failure-config, respectively. In fail-safe mode the SYS LED is

With new features & fixes, Infix grows. With the latest support for
rauc upgrades introduced with the VisionFive2, and now also for R2S,
we need to reserve room for future upgrades even when running from
an SD card.
This is a quick fix for genimge generated SD card imaages before we
get a proper installer in place that can be used both on the target
and host systems to partition and provision an eMMC, NVME, SSD, or
an SD card.

This patch set adds support for detecting and installing product/vendor
specific static factory-config and failure-config files. See the confd
README for details.
To facilitate generation, e.g., of the NETCONF SSH host keys, the confd

Since a user has access to the shell in developer mode, we might as
well allow booting through the standard boot scripts as well. This
means that a product with a bootloader only accepting images signed by
Company A can now be configured to netboot a regular developer image
without any special user interaction.
We no longer need to set bootdelay on development platforms. You can
now always get to the bootmenu with a Ctrl-C, from there you can get
to the shell if developer mode is enabled. Therefore, override the
default dev-mode detection to statically enable it on the CRB.
If we receive an option 67 (bootfile) matching http://IP/rootfs.itb,
use U-Boot's wget implementation to download the file. The web server
must listen on port 80. tftp:// is also supported.
Without a protocol prefix, assume that the bootfile should be fetched
using TFTP from ${serverip}.
Generate a boot menu, accessible with C-c during a short window, where
a user can interactively select a custom boot source and/or trigger a
factory reset of the device.
With this in place, we should always be able to unbrick a device, as
the image can be fed over the network, and local data can be ignored
by opting in to a factory reset.
Before this change, this invocation...
make O=x-x64 x86_64_defconfig
...would use the output directory...
/path/to/infix/buildroot/x-x64
...which is not the expected behavior. This would happen because
Buildroot will, naturally, expand relative paths based on _its_ top
directory.
Therefore, translate any relative paths to absolute ones based on
_Infix's_ top directory, before handing control over to Buildroot,
such that the expected...
/path/to/infix/x-x64
...output directory is used.
This tries to improve on the existing sniffer in a couple of ways:
- In addition to being usable as a context manager, also allow
explicitly starting and stopping the capture.
- Try to synchronize the start of the capture by snooping stderr and
wait for tcpdump to start up. This should eliminate the need for
sleeps before starting to send packets.
- By default, execute a safety sleep when terminating the capture to
ensure that any straggling packets have had time to arrive at their
destination.
By default, ping(1) will use a random ID in the ICMP packet. Allow
setting it to a fixed value instead.
This makes it easy to identify that particular packet in a packet
capture later on.
Let the ring-bearer^Wuser decide the policy around how VLAN PCP is
mapped to skb->priority on ingress, and back to PCP again on egress.
Either a fixed value is used for all packets, or a 1:1 mapping is done
between the two domains. By default, we follow Linux's defaults of a
fixed 0 value on both ingress and egress.
The interface in question might not exist at init:49 if some other
change requires it to be recreated from scratch, in which case it will
be removed in exit:50. Therefore, run the flush at exit:49, where it
should always still exist.
When timestamping of scripts was added, we unfortunately started to
record the exitstatus of `ts(1)`, rather than the script itself.
Refactor the metadata collection to use `time(1)` instead, which will
propagate the inferior's exitcode. This will also allow us to collect
other parameters in the future.
By default, Linux will map an IP packet's TOS field into skb->priority
when acting as a router. Unfortunately this is only globally
configurable (per network namespace), which leaves us with the
following dilemma:
If we keep reclassification enabled, then a setup like this...
vlan1 vlan2
\ /
br0
/ \
e1 e2
...would likely not work as expected because any priority information
from hardware, that might be mapped to skb->priority via vlan1's
ingress-qos-map, would then be replaced by the standard TOS-mapping on
the routing boundary.
On the other hand, if we disable reclassification, then we won't be
able to source priority information from the TOS field when no other
source is available, as is the case when the source interface is a
regular NIC.
Given that the primary use-case is to run on switchdev ports, we will
most likely always have priority information available from hardware,
which is why we opt to disable the reclassification.
If this ever becomes configurable per interface, then we could open up
the configuration to let users define the policy of which layer's
priority should take precedence.
Opportunistically look for interfaces with multiple transmit queues
and hardware support for the mqprio queuing discipline. For every
matching interface, set up mappings from kernel-internal packet
priorities, via traffic classes, to transmit queues such that as many
high priorities as possible are scheduled on separate queues.
This makes it easier to add more scripts without having to update the
finit config file, and it clarifies which of the scripts in
/libexec/infix only execute at boot.
Sync after `make update-defconfig`:
- avahi selected by mdns-alias package (all)
- iptables and ca-certs selected by other packages (r2s)

With increased use of augeas to manage users, groups, and permissions,
we seem to have reached peak complexity. Because when re-running the
same test[1] over and over, somtimes the aug_save() function fails to
actually save the changes to /etc/shadow to disk!
We have already experienced weird behavior with augeas, see comment in
deleted code, and these latest problems became the last straw. We have
decided to replace it with standard C APIs.
As a spin-off, thanks to the requried refactoring, the check_shell()
function, used by the change_nacm() callback, could be replaced with a
call to set_shell() for both "is-admin" and "non-admin" cases. This
means we now also restore Bash privileges (and not just take them away)

Since containers managed by docker runs as root, files created in bind
mounted volumes will be owned by root:root. This is a problem for
files generated during test execution, as the calling user does not
have permission to remove them.
Therefore, add a wrapper entrypoint that hooks up an exit handler that
will fixup the permissions before exiting the container.
Now that Reggie builds all supported archs there is no point in keeping
two separate (and now very similar) workflows. So we've decided to lay
