Release notes are available at https://www.openssh.com/txt/release-7.5.
Mostly a bugfix release, no major backwards-incompatible changes.
Remove deprecated `UsePrivilegeSeparation` option,
which is now mandatory.
AFAICT, this issue only occurs when sshd is socket-activated. It turns
out that the preStart script's stdout and stderr are connected to the
socket, not just the main command's. So explicitly connect stderr to
the journal and redirect stdout to stderr.
This reverts commit 1a74eedd07. It
breaks NixOps, which expects that
rm -f /etc/ssh/ssh_host_ed25519_key*
systemctl restart sshd
cat /etc/ssh/ssh_host_ed25519_key.pub
works.
This option was initially added to make it easier to use an
up-to-date list, but now that we always use an up-to-date list
from upstream, there's no point to the option.
From now on, you can either use a resolver listed by dnscrypt
upstream or a custom resolver.
Removes tcpOnly and ephemeralKeys: reifying them as nixos
options adds little beyond improved discoverability. Until
17.09 we'll automatically translate these options into extraArgs
for convenience.
Unless reifying an option is necessary for conditional
computation or greatly simplifies configuration/reduces risk of
misconfiguration, it should go into extraArgs instead.
Newer versions of DNSCrypt proxy *can* cache lookups (via
plugin); make the wording more neutral wrt. why one might want
to run the proxy in a forwarding setup.
It'd be better to do the update as an unprivileged user; for
now, we do our best to minimize the surface available. We
filter mount syscalls to prevent the process from undoing the fs
isolation.
Resolve download.dnscrypt.org using hostip with a bootstrap
resolver (hard-coded to Google Public DNS for now), to ensure
that we can get an up-to-date resolver list without working name
service lookups. This makes us more robust to the upstream
resolver list getting out of date and other DNS configuration
problems.
We use the curl --resolver switch to allow https cert validation
(we'd need to do --insecure if using just the ip addr). Note
that we don't rely on https for security but it's nice to have
it ...
Use mkMerge to make the code a little more ergonomic and easier
to follow (to my eyes, anyway ...). Also take the opportunity
to do some minor cleanups & tweaks, but no functional changes.
Set `networking.networkmanager.wifi.macAddress` or `networking.networkmanager.ethernet.macAddress`
to one of these values to change your macAddress.
* "XX:XX:XX:XX:XX:XX": set the MAC address of the interface.
* "permanent": use the permanent MAC address of the device.
* "preserve": don’t change the MAC address of the device upon activation.
* "random": generate a randomized value upon each connect.
* "stable": generate a stable, hashed MAC address.
See https://blogs.gnome.org/thaller/2016/08/26/mac-address-spoofing-in-networkmanager-1-4-0/ for more information
reason:
- We currently have an open discussion regarding a more modular
firewall (https://github.com/NixOS/nixpkgs/issues/23181) and
leaving null makes future extension easier.
- the current default might not cover all use cases (different ssh port)
and might break setups, if applied blindly
When dhcpcd instead of networkd is used, the network-online.target behaved
the same as network.target, resulting in broken services that need a working
network connectivity when being started.
This commit makes dhcpcd wait for a lease and makes it wanted by
network-online.target. In turn, network-online.target is now wanted by
multi-user.target, so it will be activated at every boot.
Recent versions of libreswan seem to omit this file, but it may be added/changed in the future. It is silly to have the service fail because a file is missing that only enriches the environment.
This fixes an issue where `nixops deploy` wouldn't restart the chrony
service when the chrony configuration changed, because it wouldn't
detect that `/etc/chrony.conf` was a dependency of the chrony service.
20e81f7c0d prevented key generation in
`preStart`, leaving the service broken for the case where the user has
no pre-existing key.
Eventually, we ought to store the state elsewhere so that `/etc` can be
read-only but for now we fix this the easy way.
* Fix the FW names
FW_REFUSE was removed and nixos-fw-input was renamed to nixos-fw.
* Update the comment (documentation) at the top
Order the chains of the main table alphabetically (like in the rest of
the file) and add nixos-fw-rpfilter (from the raw table) and nixos-drop
(used while reloading the firewall).
* Refactor the module (mainly comments)
- Move some attributes to the top for better visibility (that should
hopefully make it easier to read and understand this module without
jumping around too much).
- Add some missing examples and improve some descriptions.
- Reorder the mkOption attributes for consistency.
- Wrap lines at 72 characters.
- Use two spaces between sentences.
Using outputsToInstall the intended behaviour of including host and dnsutils
when bind is installed can be implemented instead of using symlinks to fix
installing all outputs individually with nix-env.
Fixes#19761.
* fix/asterisk-module: use unix-group for asterisk-files
* fix/asterisk-module: add configOption to use some default config-files
* fix/asterisk-module: correction of skel copy
* fix/asterisk-module: use /etc/asterisk as configDir
* fix/asterisk-module: add reload; do not restart unit
* asterisk: 13.6.0 -> 14.1.2
* fix/asterisk: compile with lua, pjsip, format_mp3
* fix/asterisk: fix indentation
* fix/asterisk: remove broken flag
- most nixos user only require time synchronisation,
while ntpd implements a battery-included ntp server (1,215 LOCs of C-Code vs 64,302)
- timesyncd support ntp server per interface (if configured through dhcp for instance)
- timesyncd is already included in the systemd package, switching to it would
save a little disk space (1,5M)
It was deprecated and removed from all modules in the tree by #18319.
The wireguard module PR (#17933) was still in the review at the time and
the deprecated usage managed to slip inside.
The configuration { services.openssh.enable = true;
services.openssh.forwardX11 = false; } caused
programs.ssh.setXAuthLocation to be set to false, which was not the
intent. The intent is that programs.ssh.setXAuthLocation should be
automatically enabled if needed or if xauth is already available.
The old etcd port 4001 is no longer enabled by default in etcd 3.
The new port is 2379 and is officially assigned by IANA.
There were still some services left that expect etcd on port 4001 by default.
This changes the default to 2379 everywhere.
It should not cause problems for users as the etcd by nix does listen on the new port only by default anyway.
The current default probe config uses the unwrapped fping binary, which
leads to an error because fping must be executed with elevated
permissions.
I fixed this by changing the path to the default binary to the
setuid-wrapped version.
This commit includes two changes:
1. A new `extraConfig` option to allow administrators to set any
vsftpd configuration option that isn't directly supported by this
derivation.
2. Correctly set the `anon_root` vsftpd option to `anonymousUserHome`
In the prestart config of the smokeping service, smokeping is executed
initially. This happens as the user root and writes some files to
$smokepingHome, which can't be overwritten by the smokeping user. This
gives an error message.
I fixed this by moving the chown step after the initial smokeping runs,
so that it also affects the generated files.
The old version would export two lists to a bash builder and do pairwise
processing on the bash side. In the new version we instead generate a
logic free builder on the Nix side. This is not only conceptually
simpler but reduces the amount of code and intermediate values.
`head -cNUM ... | tr -dc SET` might generate output containing fewer
than NUM characters. Given the limited alphabet, this could result in a
fairly weak passphrase. The construction `tr </dev/urandom | head
-cNUM`, however, is sure to give us the full `NUM`.
Currently only for the user services as NixOS handles the named system
instances slightly differently.
syncthing and syncthing-inotify are done the same way.
There are 4 parts to this:
1) Copy in the upstream unit files
2) Make the nixos module use the definition from upstream
3) Enable restarting of all instances (system and user) on resume
4) Allow the traffic in the firewall on default ports if wanted
fixes#18973
* Add extraOptions option, to pass arbitrary command line options to
atftp. Especially useful to specify which address to bind to
(--bind-addres ...).
* Improve descriptions (fix a typo, document default bind address,
don't repeat service name in systemd description + capitalize)
* Change default server directory from /var/empty to /srv/tftp, and
change types.str to types.path.
The new units mirror the upstream systemd units as closely as possible.
I could not find a reason why the service would need to be restarted on
resuming from suspend, and the upstream units also do not contain such a
restriction, so I removed the `partOf = [ "post-resume.target"]`.
This fixes#19525.
`stripHash` documentation states that it prints out the stripped name to
the stdout, but the function stored the value in `strippedName`
instead.
Basically all usages did something like
`$(stripHash $foo | echo $strippedName)` which is just braindamaged.
Fixed the implementation and all invocations.
The initial commit accidentally left in some commented code and if you were
using alerts, they simply didn't work.
Smokeping also includes some JS code for the webui allowing you to zoom into
graphs and it was not passed into the homedir. Additionally, generate
static html pages for other webservers to serve the cache directory.
Add additional options to specify sendmail path or mailhost and verify that both
are not set.
Add one extra config hook that allows you to bypass all of the invidual config
stanzas and just hand it a string.

The services/networking directory is already quite polluted and the
first point where I was looking for the offlineimap module was in
services/mail and didn't find it there.
Offlineimap already has IMAP in its name and clearly belongs to the
"mail" category so let's move it there.
Tested by evaluating a configuration with services.offlineimap enabled.

Coercing the derivation to string causes the package to be built during
evaluation rather than during actual realization which is completely
unnecessary because we don't need additional Nix expression information
for the package (nor do we need it for the service).

While entering the chroot should provide the same amount of isolation,
the preStart script will run with full root privileges and so would
benefit from some isolation as well (in particular due to
unbound-anchor, which can perform network I/O).
1. The preStart script ensures consistent ownership, even if the unbound
user's uid has changed
2. The unbound daemon does not generate data that needs to be private to
it, so it would not matter that a different service would end up
owning its data (as long as unbound remains enabled, it should reclaim
ownership soon enough anyway).
Thus, there's no clear benefit to allocate a dedicated uid for the
unbound service. This releases uid/gid 48.
Also, because the preStart script creates the data directory, there's no
need to specify a homedir or ask for its creation.
