* nixos/nftables: Allow use with iptables
Since iptables and nftables do not actually conflict with each other, there's no real reason to artificially prevent people from combining them.
In fact, this practice is known to cause issues like #88643, which is fixed by this commit.
Empty parantheses are not supported in regular expressions on
Darwin/macOS. The old regular expression produces an error during
evaluation. This commit fixes that.
Nix‘s `builtins.match` works with extend POSIX regular expressions. The
specification for these regular expression states[^1] that the result
for a left paranthesis immediately followed by a right paranthesis
outside of a bracket expression is undefined.

Add a new type, inheriting 'types.str' but checking whether the value
doesn't contain any newline characters.
The motivation comes from a problem with the
'users.users.${u}.openssh.authorizedKeys' option.
It is easy to unintentionally insert a newline character at the end of a
string, or even in the middle, for example:
restricted_ssh_keys = command: keys:
let
prefix = ''
command="${command}",no-pty,no-agent-forwarding,no-port-forwarding,no-X11-forwarding
'';
in map (key: "${prefix} ${key}") keys;
The 'prefix' string ends with a newline, which ends up in the middle of
a key entry after a few manipulations.
This is problematic because the key file is built by concatenating all
the keys with 'concatStringsSep "\n"', with result in two entries for
the faulty key:
''
command="...",options...
MY_KEY
''
This is hard to debug and might be dangerous. This is now caught at
build time.
network.target is reached earlier, but with much fewer services
available. DNS is likely to be not functional before
network-online.target, so waiting for that seems better for that reason
alone. the existing backends for network-online.target all seem to do
reasonable things (wait until all links are in *some* stable state), so
we shouldn't lose anything from waiting.
Still actively developed and yet stuck on python2. Also marked as
vulnerable and their issue tracker contains yet another security issue
reported in 2021/10 that the upstream hasn't acknowledged yet.
Mind blown.
Closes: #135543, #97274, #97275
It turns out it's actually possible to fall back to WPA2 in case the
authentication fails with WPA3. This was suggested to me in the hostapd
mailing list: add another network block with only WPA2 and lower
priority, for each network with WPA3. For clients with missing/broken
WPA3, wpa_supplicant will:
1. try the network block with higher priority first
2. fail and temporarily disable the network block
3. try the fallback network block and connect
This takes a little more time (still <5s) because wpa_supplicant
retries a couple times before disabling the network block, but it allows
old client to gracefully fall back to WPA2 on mixed WPA2/WPA3 networks.
To avoid downgrade attacks, clients with proper WPA3 should disable
this; in the future we may want to disable this option by default.
This is a useful utility for monitoring network performance over time
using a combination of MTR and Prometheus. Also adding a service definition.

Alternative solution to PR #152443.
This fixes authentication failures to WPA3 networks (issue #151729)
by enabling protected management frames.
Note: old client without 802.11w support will still fail.
When startWhenNeeded is enabled, a brute force attack on sshd will cause
systemd to shut down the socket, locking out all SSH access to the machine.
Setting TriggerLimitIntervalSec to 0 disables this behavior.
This never configured where SNI should log to, as it's up to the user to
provide the full sniproxy config (which can be configured to log to a
file).
This option only produced a ExecStartPre script that created the folder.
Let's use LogsDirectory to create it. In case users want to use another
directory for logs, they can override LogsDirectory or set their own
ExecStartPre script.
