This ensures that "journalctl -u display-manager" does what you would
expect in 2016. However, the main reason is to ensure that our VM
tests show the output of the X server.
A slight problem is that with KDE user switching, messages from the
various X servers end up in the same place. However, that's an
improvement over the previous situation, where the second X server
would overwrite the /var/log/X.0.log of the first. (This was caused by
the fact that we were passing a hard-coded value for -logfile.)
For now, leave the old implementation under `man-old` attribute.

Move Subsonic state directory from `/var/subsonic` to

application to put its state directory there.
Also, automatically set the home directory of the `subsonic` user to the

value hardcoded in the module. This keeps the home directory of the
`subsonic` user and the state directory for the Subsonic application in

The chroot caps restriction disallows chroot'ed processes from running
any command that requires `CAP_SYS_ADMIN`, breaking `nixos-rebuild`. See
e.g., https://github.com/NixOS/nixpkgs/issues/15293
This significantly weakens chroot protections, but to break
nixos-rebuild out of the box is too severe.
The list of public proxies is updated now and again and it's probably a
good idea to always work from the most recent list, rather than the one
that is shipped with the release. This can be crucial in case of
resolvers that are revealed to have gone rogue or otherwise have been
compromised.
Unfortunately, pkill doesn't distinguish between kernel and user space
processes, so we need to make sure we don't accidentally kill kernel
threads.
Normally, a kernel thread ignores all signals, but there are a few that
do. A quick grep on the kernel source tree (as of kernel 4.6.0) shows
the following source files which use allow_signal():
drivers/isdn/mISDN/l1oip_core.c
drivers/md/md.c
drivers/misc/mic/cosm/cosm_scif_server.c
drivers/misc/mic/cosm_client/cosm_scif_client.c
drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.c
drivers/staging/rtl8188eu/core/rtw_cmd.c
drivers/staging/rtl8712/rtl8712_cmd.c
drivers/target/iscsi/iscsi_target.c
drivers/target/iscsi/iscsi_target_login.c
drivers/target/iscsi/iscsi_target_nego.c
drivers/usb/atm/usbatm.c
drivers/usb/gadget/function/f_mass_storage.c
fs/jffs2/background.c
fs/lockd/clntlock.c
fs/lockd/svc.c
fs/nfs/nfs4state.c
fs/nfsd/nfssvc.c
While not all of these are necessarily kthreads and some functionality
may still be unimpeded, it's still quite harmful and can cause
unexpected side-effects, especially because some of these kthreads are
storage-related (which we obviously don't want to kill during bootup).
During discussion at #15226, @dezgeg suggested the following
implementation:
for pid in $(pgrep -v -f '@'); do
if [ "$(cat /proc/$pid/cmdline)" != "" ]; then
kill -9 "$pid"
fi
done
This has a few downsides:
* User space processes which use an empty string in their command line
won't be killed.
* It results in errors during bootup because some shell-related
processes are already terminated (maybe it's pgrep itself, haven't
checked).
* The @ is searched within the full command line, not just at the
beginning of the string. Of course, we already had this until now, so
it's not a problem of his implementation.
I posted an alternative implementation which doesn't suffer from the
first point, but even that one wasn't sufficient:
for pid in $(pgrep -v -f '^@'); do
readlink "/proc/$pid/exe" &> /dev/null || continue
echo "$pid"
done | xargs kill -9
This one spawns a subshell, which would be included in the processes to
kill and actually kills itself during the process.
So what we have now is even checking whether the shell process itself is
in the list to kill and avoids killing it just to be sure.
Also, we don't spawn a subshell anymore and use /proc/$pid/exe to
distinguish between user space and kernel processes like in the comments
of the following StackOverflow answer:
http://stackoverflow.com/a/12231039
We don't need to take care of terminating processes, because what we
actually want IS to terminate the processes.
The only point where this (and any previous) approach falls short if we
have processes that act like fork bombs, because they might spawn
additional processes between the pgrep and the killing. We can only
address this with process/control groups and this still won't save us
because the root user can escape from that as well.

More reasons why the current approach is bad and we should remove it,
from @coreyoconnor in
https://github.com/NixOS/nixpkgs/issues/14991#issuecomment-216572571:
1. Repeatedly curling for a specific human-readable string to
determine "Active" is fragile. For instance, what happens when jenkins
is localized?
2. The time jenkins takes to initializes is variable. This (at least
used to) depend on the number of jobs and any plugin upgrades requested.
3. Jenkins can be requested to restart from the UI. Which will not
affect the status of the service. This means that the service being
"active" does not imply jenkins is initialized. Downstream services
cannot assume jenkins is initialized if the service is active. Might
as well accept that and remove the initialized test from service
startup.

`dbus-launch` is executed early in the script, before desktop managers
had a chance to setup the environment. If DBus activation is used,
applications launched by this may therefore lack necessary environment

With the merge of the closure-size branch, most packages now have
multiple outputs. One of these packages is gnutls, so previously
everything that we needed was to reference "${gnutls}/bin/..." and now
we need to use "${gnutls.bin}/bin/...".
So it's not a very big issue to fix.

This adds a Taskserver module along with documentation and a small

organisations, users and groups.
Taskserver is the server component of Taskwarrior, a TODO list

This is simply to add configuration lines to the generated configuration
file. The reason why I didn't went for an attribute set is that the
taskdrc file format doesn't map very well on Nix attributes, for example
the following can be set in taskdrc:
server = somestring
server.key = anotherstring
In order to use a Nix attribute set for that, it would be way too
complicated, for example if we want to represent the mentioned example
we'd have to do something like this:
{ server._top = somestring;
server.key = anotherstring;
}
Of course, this would work as well but nothing is more simple than just
appending raw strings.

Whenever the nixos-taskserver tool was invoked manually for creating an
organisation/group/user we now add an empty file called .imperative to
the data directory.
During the preStart of the Taskserver service, we use process-json which
in turn now checks whether those .imperative files exist and if so, it
doesn't do anything with it.
This should now ensure that whenever there is a manually created user,
it doesn't get killed off by the declarative configuration in case it
shouldn't exist within that configuration.
In addition, we also add a small subtest to check whether this is
happening or not and fail if the imperatively created user got deleted
by process-json.

Now we finally can delete organisations, groups and users along with
certificate revocation. The new subtests now make sure that the client

and just a single user).
If we use the imperative way to add and delete users, we have to restart
the Taskserver in order for the CRL to be effective.
However, by using the declarative configuration we now get this for
free, because removing a user will also restart the service and thus its
client certificate will end up in the CRL.

Unfortunately we don't have a better way to check whether the reload has

to work, a full restart needs to be done.

If we want to revoke client certificates and want the server to actually

NixOS module options and creates/deletes the users accordingly.
Note that this still has a two issues left to solve in this area:
* Deletion is not supported yet.
* If a user is created imperatively, the next run of process-json will
delete it once deletion is supported.
So we need to implement deletion and a way to mark organisations, users

This module adds an option `security.hideProcessInformation` that, when
enabled, restricts access to process information such as command-line
arguments to the process owner. The module adds a static group "proc"
whose members are exempt from process information hiding.
Ideally, this feature would be implemented by simply adding the
appropriate mount options to `fileSystems."/proc".fsOptions`, but this
was found to not work in vmtests. To ensure that process information
hiding is enforced, we use a systemd service unit that remounts `/proc`
after `systemd-remount-fs.service` has completed.
To verify the correctness of the feature, simple tests were added to
nixos/tests/misc: the test ensures that unprivileged users cannot see
process information owned by another user, while members of "proc" CAN.

Finally, this is where we declaratively set up our organisations and

This automatically sets up "alice" and "bob" for the "NixOS"
organisation, generates the required client keys and signs it via the
CA.
However, we still need to use nixos-taskdctl export-user in order to
import these certificates on the client.

It's a helper for NixOS systems to make it easier to handle CA
certificate signing, similar to what taskd provides but comes preseeded
with the values from the system configuration.
The tool is very limited at the moment and only allows to *add*
organisations, users and groups. Deletion and suspension however is much
simpler to implement, because we don't need to handle certificate
signing.
Another limitation is that we don't take into account whether
certificates and keys are already set in the system configuration and if
they're set it will fail spectacularly.
For passing the commands to the taskd command, we're using a small C
program which does setuid() and setgid() to the Taskserver user and
group, because runuser(1) needs PAM (quite pointless if you're already
root) and su(1) doesn't allow for setting the group and setgid()s to the
default group of the user, so it even doesn't work in conjunction with
sg(1).
In summary, we now have a shiny nixos-taskdctl command, which lets us do
things like:
nixos-taskdctl add-org NixOS
nixos-taskdctl add-user NixOS alice
nixos-taskdctl export-user NixOS alice
The last command writes a series of shell commands to stdout, which then
can be imported on the client by piping it into a shell as well as doing
it for example via SSH:
ssh root@server nixos-taskdctl export-user NixOS alice | sh
Of course, in terms of security we need to improve this even further so
that we generate the private key on the client and just send a CSR to
the server so that we don't need to push any secrets over the wire.

Using just the host for the common name *and* for listening on the port
is quite a bad idea if you want to listen on something like :: or an
internal IP address which is proxied/tunneled to the outside.
Hence this separates host and fqdn.

The server starts up without that option anyway, but it complains about
its value not being set. As we probably want to have access to that
configuration value anyway, let's expose this via the NixOS module as
well.
