Exclude static 192.168.*.2 addresses from the dynamic address range to
prevent different interfaces from getting the same address.
Seems like configuring a fixed IPv4 address does not automatically
exclude it from the dynamic address range.
Should fix occasional failures of
nixos.tests.networking.scripted.macvlan and possibly other networking
tests relying on DHCP.
This modifies the `router` to not give out a range of IP addresses but
only give out a fixed address based on the MAC address using the
`services.dhcpd4.machines` option.
To get access to the MAC address the `qemuNicMac` function is defined
and exported from `qemu-flags.nix`.
This was whitespace-sensitive, kept fighting with my editor and broke
the tests easily. To fix this, let python convert the output to
individual lines, and strip whitespace from them before comparing.
This mirrors the behaviour of systemd - It's udev that parses `.link`
files, not `systemd-networkd`.
This was originally applied in 36ef112a47,
but was reverted due to 1115959a8d causing
evaluation errors on hydra.
...even when networkd is disabled
This reverts commit ce78f3ac70, reversing
changes made to dc34da0755.
I'm sorry; Hydra has been unable to evaluate, always returning
> error: unexpected EOF reading a line
and I've been unable to reproduce the problem locally. Bisecting
pointed to this merge, but I still can't see what exactly was wrong.
The networking.virtual test does not work with networkd yet, for
multiple reasons:
- network-online.target is not reached, because tun0 and tap0 are
considered as required for online but _not_ brought up or assigned
the configured addresses
- the commands later in the test rely on some units from the scripted
network setup
cc @fpletz networkd exper
cc @globin we looked at this together
He prefers to contribute to his own nixpkgs fork triton.
Since he is still marked as maintainer in many packages
this leaves the wrong impression he still maintains those.
Generated reverse path filtering rules for the macvlan interface
seem to be incorrect, causing the test to fail - sometimes or always,
depending on the dhcpcd version used.
- Disable reverse path checking temporarily to avoid blocking the channel
- Print more diagnostic information for debugging
Previously services depending on network-online.target would wait until
dhcpcd times out if it was enabled and a static network address
configuration was used. Setting the default gateway statically is enough
for the networking to be considered online.
This also adjusts the relevant networking tests to wait for
network-online.target instead of just network.target.
After the change of the bonding options, the examples were not quite correct.
The diff is over-the top because the new `let` needs everything indented.
Also add a small docstring to the `networkd` attr in the networking test.
reason: after the upgrade of iputils from 20151218 to 20161105
functionality of ping6 and tracepath6 was merged into ping and tracepath.
Ping is now mostly a drop-in replacment for ping6, except that selecting a
specific interface is done by encoding it into the address (ex.: fe80::1%eth0)
rather then specifing it with the `-I` flag.
Until now the four attributes available very selectively provided a small
subset, while copying upstream documentation.
We make driver options an arbitrary key-value set and point to kernel
documentation, which is always up-to-date. This way every option can be set.
The four already existing options are deprecated with a warning.
So far the networking test expression only generated a single test
depending on the passed "test" attribute. This makes it difficult to
autodiscover the subtests with our shiny new callSubTests function.
This change essentially doesn't change the behaviour of the subtests but
rather exposes them as an attribute set instead of relying on a
particular input argument.
The useNetworkd argument still exists however.

It serves as a regression test, because right now if you enable
networking.useNetworkd the default loopback interface doesn't get
assigned any IP addresses.
To be sure, I have bisected this and it has been introduced with the
update to systemd 228 in 1da87d4.
Only the "scripted" networking tests have to succeed in order to trigger
a channel update of nixos-unstable, so I'm leaving this test as broken
and we have to figure out next what's the *exact* reason for the
breakage.
