mysql already has its socket path hardcoded to to
/run/mysqld/mysqld.sock.
There's not much value in making the pidDir configurable, which also
points to /run/mysqld by default.
We only seem to use `services.mysql.pidDir` in the wordpress startup
script, to wait for mysql to boot up, but we can also simply wait on the
(hardcoded) socket location too.
A much nicer way to accomplish that would be to properly describe a
dependency on mysqld.service. This however is not easily doable, due to
how the apache-httpd module was designed.
As we don't need to setup data directories from ExecStartPre= scripts
anymore, which required root, but use systemd.tmpfiles.rules instead,
everything can be run as just the mysql user.
Some packages like `ibus-engines.typing-booster` require the dictionary
`fr_FR.dic` to provide proper support for the french language.
Until now the hunspell package set of nixpkgs didn't provide this
dictionary. It has been recommended to use `fr-moderne` as base and link
`fr_FR.dic` from it as done by other distros such as ArchLinux.
See https://github.com/NixOS/nixpkgs/issues/46940#issuecomment-423684570Fixes#46940
Commit 29d7d8f44d has introduced another
section with the ID "sec-release-19.09-incompatibilities", which
subsequently causes the build to fail.
I just merged both sections and the manual is now building again.

Currently if you want to properly chroot a systemd service, you could do
it using BindReadOnlyPaths=/nix/store or use a separate derivation which
gathers the runtime closure of the service you want to chroot. The
former is the easier method and there is also a method directly offered
by systemd, called ProtectSystem, which still leaves the whole store
accessible. The latter however is a bit more involved, because you need
to bind-mount each store path of the runtime closure of the service you
want to chroot.
This can be achieved using pkgs.closureInfo and a small derivation that
packs everything into a systemd unit, which later can be added to
systemd.packages.
However, this process is a bit tedious, so the changes here implement
this in a more generic way.
Now if you want to chroot a systemd service, all you need to do is:
{
systemd.services.myservice = {
description = "My Shiny Service";
wantedBy = [ "multi-user.target" ];
confinement.enable = true;
serviceConfig.ExecStart = "${pkgs.myservice}/bin/myservice";
};
}
If more than the dependencies for the ExecStart* and ExecStop* (which
btw. also includes script and {pre,post}Start) need to be in the chroot,
it can be specified using the confinement.packages option. By default
(which uses the full-apivfs confinement mode), a user namespace is set
up as well and /proc, /sys and /dev are mounted appropriately.
In addition - and by default - a /bin/sh executable is provided, which
is useful for most programs that use the system() C library call to
execute commands via shell.
Unfortunately, there are a few limitations at the moment. The first
being that DynamicUser doesn't work in conjunction with tmpfs, because
systemd seems to ignore the TemporaryFileSystem option if DynamicUser is
enabled. I started implementing a workaround to do this, but I decided
to not include it as part of this pull request, because it needs a lot
more testing to ensure it's consistent with the behaviour without
DynamicUser.
The second limitation/issue is that RootDirectoryStartOnly doesn't work
right now, because it only affects the RootDirectory option and doesn't
include/exclude the individual bind mounts or the tmpfs.
A quirk we do have right now is that systemd tries to create a /usr
directory within the chroot, which subsequently fails. Fortunately, this
is just an ugly error and not a hard failure.
The changes also come with a changelog entry for NixOS 19.03, which is
why I asked for a vote of the NixOS 19.03 stable maintainers whether to
include it (I admit it's a bit late a few days before official release,
sorry for that):
@samueldr:
Via pull request comment[1]:
+1 for backporting as this only enhances the feature set of nixos,
and does not (at a glance) change existing behaviours.
Via IRC:
new feature: -1, tests +1, we're at zero, self-contained, with no
global effects without actively using it, +1, I think it's good
@lheckemann:
Via pull request comment[2]:
I'm neutral on backporting. On the one hand, as @samueldr says,
this doesn't change any existing functionality. On the other hand,
it's a new feature and we're well past the feature freeze, which
AFAIU is intended so that new, potentially buggy features aren't
introduced in the "stabilisation period". It is a cool feature
though? :)
A few other people on IRC didn't have opposition either against late
inclusion into NixOS 19.03:
@edolstra: "I'm not against it"
@Infinisil: "+1 from me as well"
@grahamc: "IMO its up to the RMs"
So that makes +1 from @samueldr, 0 from @lheckemann, 0 from @edolstra
and +1 from @Infinisil (even though he's not a release manager) and no
opposition from anyone, which is the reason why I'm merging this right
now.
I also would like to thank @Infinisil, @edolstra and @danbst for their
reviews.

eb90d97009 broke nslcd, as /run/nslcd was
created/chowned as root user, while nslcd wants to do parts as nslcd
user.
This commit changes the nslcd to run with the proper uid/gid from the
start (through User= and Group=), so the RuntimeDirectory has proper
permissions, too.
In some cases, secrets are baked into nslcd's config file during startup
(so we don't want to provide it from the store).
This config file is normally hard-wired to /etc/nslcd.conf, but we don't
want to use PermissionsStartOnly anymore (#56265), and activation
scripts are ugly, so redirect /etc/nslcd.conf to /run/nslcd/nslcd.conf,
which now gets provisioned inside ExecStartPre=.
This change requires the files referenced to in
users.ldap.bind.passwordFile and users.ldap.daemon.rootpwmodpwFile to be
readable by the nslcd user (in the non-nslcd case, this was already the
case for users.ldap.bind.passwordFile)
fixes#57783
First of all, the reason I added this to the "highlights" section is
that we want users to be aware of these options, because in the end we
really want to decrease the attack surface of NixOS services and this is
a step towards improving that situation.
The reason why I'm adding this to the changelog of the NixOS 19.03
release instead of 19.09 is that it makes backporting services that use
these options easier. Doing the backport of the confinement module after
the official release would mean that it's not part of the release
announcement and potentially could fall under the radar of most users.
These options and the whole module also do not change anything in
existing services or affect other modules, so they're purely optional.
Adding this "last minute" to the 19.03 release doesn't hurt and is
probably a good preparation for the next months where we hopefully
confine as much services as we can :-)
I also have asked @samueldr and @lheckemann, whether they're okay with
the inclusion in 19.03. While so far only @samueldr has accepted the
change, we can still move the changelog entry to the NixOS 19.09 release
notes in case @lheckemann rejects it.

Compatibility with other distributions/software and expectation
of users coming from other systems should have higher priority over consistency.
In particular this fixes#51375, where the NetworkManager-wait-online.service
broke as a result of this.
This is a backwards-incompatible change and while it won't probably
affect a whole lot of users, it makes sense to give them a heads-up
anyway.

The explicit remove helped to uncover some hidden uses of `optionSet`
in NixOps. However it makes life harder for end-users of NixOps - it will
be impossible to deploy 19.03 systems with old NixOps, but there is no
new release of NixOps with `optionSet` fixes.
Also, "deprecation" process isn't well defined. Even that `optionSet` was
declared "deprecated" for many years, it was never announced. Hence, I
leave "deprecation" announce. Then, 3 releases after announce,
we can announce removal of this feature.
This type has to be removed, not `throw`-ed in runtime, because it makes
some perfectly fine code to fail. For example:
```
$ nix-instantiate --eval -E '(import <nixpkgs/lib>).types' --strict
trace: `types.list` is deprecated; use `types.listOf` instead
error: types.optionSet is deprecated; use types.submodule instead
(use '--show-trace' to show detailed location information)
```
Before this change `man 5 configuration.nix` would only show options of modules in
the `baseModules` set, which consists only of the list of modules in
`nixos/modules/module-list.nix`
With this change applied and `documentation.nixos.includeAllModules` option enabled
all modules included in `configuration.nix` file will be used instead.
This makes configurations with custom modules self-documenting. It also means
that importing non-`baseModules` modules like `gce.nix` or `azure.nix`
will make their documentation available in `man 5 configuration.nix`.
`documentation.nixos.includeAllModules` is currently set to `false` by
default as enabling it usually uncovers bugs and prevents evaluation.
It should be set to `true` in a release or two.
This was originally implemented in #47177, edited for more configurability,
documented and rebased onto master by @oxij.
system-sendmail allows all sendmail's to be auto-detected, including on
non-NixOS systems. This is, to me, a better UX than having to manually
override the sendmailPath argument.
In exchange, it is a breach of retro-compatibility. Given right now I
can't see any uses for sendmailPath other than what is supported by
system-sendmail, I didn't keep it, but it'd be possible to allow
sendmailPath to override the choice of sendmail from system-sendmail.

The motivation for this is that some applications are unaware
of this feature and can set their volume to 100% on startup
harming people ears and possiblly blowing someone's audio
setup.
I noticed this in #54594 and by extension epiphany[0].
Please also note that many other distros have this default for
the reason outlined above.

- add `zramSwap.algorithm` option, which allows to change compressor
declaratively. zstd as default
- add `zramSwap.swapDevices` option, which allows to define how many zram
devices will be used as swap. Rest devices can be managed freely
- simpler floating calculations
- fix udev race condition
- some documentation changes
- replaced `/sys/block/zram*` handling with `zramctl`, because I had occasional
"Device is busy" error (looks like zram has to be configured in predefined order)
- added `memoryPercent` and `algorithm` as restart triggers. I think, it was
a bug that changing `memoryPercent` in configuration wasn't applied immediately.
- removed a bind to .swap device. While it looks natural (when swap device goes
off, so should zram device), it wasn't implemented properly. This caused problems
with swapon/swapoff:
```
$ cat /proc/swaps
Filename Type Size Used Priority
/dev/zram0 partition 8166024 0 -2
/var/swapfile file 5119996 5120 1
$ sudo swapoff -a
$ sudo swapon -a
swapon: /dev/zram0: read swap header failed
$ cat /proc/swaps
Filename Type Size Used Priority
/var/swapfile file 5119996 0 1
```
This adds a NixOS option for setting the CPU max and min frequencies
with `cpufreq`. The two options that have been added are:
- `powerManagement.cpufreq.max`
- `powerManagement.cpufreq.min`
It also adds an alias to the `powerManagement.cpuFreqGovernor` option as
`powerManagement.cpufreq.governor`. This updates the installer to use
the new option name. It also updates the manual with a note about
the new name.
Having pam_unix set to "sufficient" means early-succeeding account
management group, as soon as pam_unix.so is succeeding.
This is not sufficient. For example, nixos modules might install nss
modules for user lookup, so pam_unix.so succeeds, and we end the stack
successfully, even though other pam account modules might want to do
more extensive checks.
Other distros seem to set pam_unix.so to 'required', so if there are
other pam modules in that management group, they get a chance to do some
validation too.
For SSSD, @PsyanticY already added a workaround knob in
https://github.com/NixOS/nixpkgs/pull/31969, while stating this should
be the default anyway.
I did some thinking in what could break - after this commit, we require
pam_unix to succeed, means we require `getent passwd $username` to
return something.
This is the case for all local users due to the passwd nss module, and
also the case for all modules installing their nss module to
nsswitch.conf - true for ldap (if not explicitly disabled) and sssd.
I'm not so sure about krb5, cc @eqyiel for opinions. Is there some nss
module loaded? Should the pam account module be placed before pam_unix?
We don't drop the `security.pam.services.<name?>.sssdStrictAccess`
option, as it's also used some lines below to tweak error behaviour
inside the pam sssd module itself (by changing it's 'control' field).
This is also required to get admin login for Google OS Login working
(#51566), as their pam_oslogin_admin accounts module takes care of sudo
configuration.
pkgs.owncloud still pointed to owncloud 7.0.15 (from May 13 2016)

TrueCrypt has been retired for a while now and the source archive we
pointed to is gone. Moreover the VeraCrypt fork is available, maintained
and fixes issues previous audits found in TrueCrypt.
Nixpkgs' channel currently can't move forward so long as there is a
trace in evaluating the top-level arguments. Which means that it isn't
possible to add a warning message to warn users of future package
removal.
So the only way forward appears to be just removing the alias
altogether.

This is taken from the 18.09 change, which was reverted on release-18.09
but not master. The now-false 18.09 release notes were just removed from
master in 29854e2426, but since the
underlying change is still there, release notes for 19.03 are warranted.
This commit takes the now-reverted release notes and reuses them for
that.
Fixed minor issue where kube-addon manager complaints about
/opt/namespace.yaml missing.
Added release notes with reference to Kubernetes 1.11 release notes.
closes#43882
This adds a release notes entry to make users (and especially
developers) aware so they no longer need to use </para><para> in option
descriptions as this is now done automatically on every two consecutive

Switch from slim to lightdm as the display-manager.

When rebuilding you have to manually run `systemctl --user
daemon-reload`. It gathers all authenticated users using
`loginctl list-user` and runs `daemon-reload` for each of them.
This is a first step towards a `nixos-rebuild` which is able to reload
user units from systemd. The entire task is fairly hard, however I
consider this patch usable as it allows to restart units without running
`daemon-reload` for each authenticated user.
This reverts commit 095fe5b43d.
Pointless renames considered harmful. All they do is force people to
spend extra work updating their configs for no benefit, and hindering
the ability to switch between unstable and stable versions of NixOS.
Like, what was the value of having the "nixos." there? I mean, by
definition anything in a NixOS module has something to do with NixOS...
Kubernetes dashboard currently has cluster admin permissions,
which is not recommended.
- Renamed option "services.kubernetes.addons.dashboard.enableRBAC" to "services.kubernetes.addons.dashboard.rbac.enable"
- Added option "services.kubernetes.addons.dashboard.rbac.clusterAdmin", default = false.
- Setting recommended minimal permissions for the dashboard in accordance with https://github.com/kubernetes/dashboard/wiki/Installation
- Updated release note for 18.09.
- Added option 'cni.configDir' to allow for having CNI config outside of nix-store
Existing behavior (writing verbatim CNI conf-files to nix-store) is still available.
- Removed unused option 'apiserver.publicAddress' and changed 'apiserver.address' to 'bindAddress'
This conforms better to k8s docs and removes existing --bind-address hardcoding to 0.0.0.0
- Fixed c/p mistake in apiserver systemd unit description
- Updated 18.09 release notes to reflect changes to existing options
And fixed some typos from previous PR
- Make docker images for Kubernetes Dashboard and kube-dns configurable
