* the lua necessary is quite wordy, but it's less of a hack than
post-processing the rules file with pseudo-sed to get rid of `elements
= { }` lines
* also switch from stop/starting the firewall service to using a
signal, so that we don't go briefly offline every time a new interface
appears
There is nothing in this commit except for the changes made by
nix-shell -p nixfmt-rfc-style --run "nixfmt ."
If this has mucked up your open branches then sorry about that. You
can probably nixfmt them to match before merging
- zones are an attrset of name -> [interface-service]
- the firewall will create empty "ifname" sets for each zone name
in each address family (ip, ip6)
- then watch the interface services, and add the "ifname" outputs
to the corresponding sets when they appear
This commit only adds the empty sets
a firewall with no configuration will get a relatively sane ruleset. a
firewall with `extraRules` will get them deep merged into the default
rules. Specifying `rules` will override the defaults
