The fix for #62874 introduced a race condition on startup: the postStart
commands that configure the firewall run concurrently with sshguard's
creation of the ipsets that the rules depend on. Unfortunately iptables
fails hard when referencing an ipset that doesn't exist, so this causes
non-deterministic crashlooping until sshguard wins the race.
This change fixes that race condition by always creating the ipset and
reconfiguring the firewall before starting sshguard, so that the order
of operations is always deterministic.
This change also cleans up the ipsets on sshguard shutdown, so that
removing sshguard from a running system doesn't leave state behind.
Fixes#65985.
Upstream switched to a different type of ipset table, whereas we
create ipset in post-start which overrides upstream, and renders
sshguard ineffective.
Remove ipset creation from post-start, and let it get automatically
by upstream script (sshg-fw-ipset) as part of startup
This is just usbguard without the Qt GUI that brings in Qt dependencies.
Remove pandoc to reduce closure size. The usbguard build appears to
use it only for spell checking.
Remove asciidoctor because 0.7.1 switched to asciidoc. But don't add
a dependency on asciidoc, because that causes the build fails on
external DTDs.
The two directories KDB and PTree do not exist before the SKS DB is
build for the first time. If /var/db/sks is empty and the module is
enabled via "services.sks.enable = true;" the following error will
occur:
...-unit-script-sks-db-pre-start[xxx]:
ln: failed to create symbolic link 'KDB/DB_CONFIG': No such file or directory
To avoid this both links have to be created after the DB is build.
Note: Creating the directories manually might be better but the initial
build might be skipped as a result:
unit-script-sks-db-pre-start[xxxxx]: KeyDB directory already exists. Exiting.
unit-script-sks-db-pre-start[xxxxx]: PTree directory already exists. Exiting.
Unfortunately the changes in ab5dcc7068
introduced a typo (took me a while to spot that...) that broke the
whole module (or at least the sks-db systemd unit).
The systemd unit was failing with the following error message:
...-unit-script-sks-db-pre-start[xxx]: KDB/DB_CONFIG exists but is not a symlink.
1. Allow syslog identifiers with special characters
2. Do not write a pid file as we are running in foreground anyway
3. Clean up the module for readability
Without this, when deploying using nixops, restarting sshguard would make
nixops show an error about restarting the service although the service is
actually being restarted.
Tor requires ``SOCKSPort 0`` when non-anonymous hidden services are
enabled. If the configuration doesn't enable Tor client features,
generate a configuration file that explicitly includes this disabling
to allow such non-anonymous hidden services to be created (note that
doing so still requires additional configuration). See #48622.
That way the built-in web server is usable by default but users can use
$HOME/web directly (instead of having to use a symlink), if they want to
customize the webpage.
Without a group the gid will default to 65534 (2^16 - 2) which maps to
"nogroup". IMO it makes more sense to explicitly set a valid group.
Adding pkgs.sks to environment.systemPackages is not required (IIRC we
want to avoid bloating environment.systemPackages). Instead it seems
like a better idea to make the relevant binaries available to the user
sks and enable useDefaultShell so that "su -l sks" can be used for
manual interaction (that way the files will always have the correct
owner).
- based on module originally written by @srhb
- complies with available options in cfssl v1.3.2
- uid and gid 299 reserved in ids.nix
- added simple nixos test case
