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.
Every interactive zsh sources /etc/zshrc (see STARTUP/SHUTDOWN FILES in zshautll(1))
Therefor every interactive zsh process will respect the content of these variables.
Using `export` will also lead to child processes inheriting this value.
This leads to problems, if other interactive shells are spawned such as bash,
because they use an incomptabible history format (without timestamps).
There seems to be also cases, where the local HISTSIZE in ~/.zshrc is
not sourced but /etc/zshrc, which leads to history truncation in other shells.

This basic module allows you to specify the tmux configuration.
As great as tmux is, some of the defaults are pretty awful, so having a
way to specify the config really helps.
This reverts commit e8e8164f34. I
misread the original commit as adding the "which" package, but it only
adds it to base.nix. So then the original motivation (making it work
in subshells) doesn't hold. Note that we already have some convenience
aliases that don't work in subshells either (such as "ll").
This reverts most of 89e983786a, as those references are sanitized now.
Fixes#10039, at least most of it.
The `sane` case wasn't fixed, as it calls a *function* in pkgs to get
the default value.
- Now `pkg.outputUnspecified = true` but this attribute is missing in
every output, so we can recognize whether the user chose or not.
If (s)he didn't choose, we put `pkg.bin or pkg.out or pkg` into
`systemPackages`.
- `outputsToLink` is replaced by `extraOutputsToLink`.
We add extra outputs *regardless* of whether the user chose anything.
It's mainly meant for outputs with docs and debug symbols.
- Note that as a result, some libraries will disappear from system path.
If we limit SSH_ASKPASS to interactive shells, users are unable to trigger
the ssh-passphrase dialog from their desktop environment autostart scripts.
Usecase: I call ssh-add during my desktop environment autostart and want to have
the passphrase dialog immediately after startup.
For this to work, SSH_ASKPASS needs to be propagated properly on
non-interactive shells.
- add missing types in module definitions
- add missing 'defaultText' in module definitions

The idea that the interactive bash prompt isn't set in case of TERM=dumb
is intended to fix problems when other machines log remotely into a
NixOS installation via Tramp. A side-effect that change was, however,
that Emacs' shell-mode no longer had a correct prompt. I suppose the
presence of
INSIDE_EMACS=24.5.2,comint
is a sufficiently unique indication that the current interactive shell
is running inside of an Emacs and that the prompt can thus be configured
safely.
This reverts commit a8eb2a6a81. OpenSSH
7.0 is causing too many interoperability problems so soon before the
15.08 release.
For instance, it causes NixOps EC2 initial deployments to fail with
"REMOTE HOST IDENTIFICATION HAS CHANGED". This is because the client
knows the server's ssh-dss host key, but this key is no longer
accepted by default. Setting "HostKeyAlgorithms" to "+ssh-dss" does
not work because it causes ssh-dss to be ordered after
"ecdsa-sha2-nistp521", which the server also offers. (Normally, ssh
prioritizes host key algorithms for which the client has a known host
key, but not if you set HostKeyAlgorithms.)
`man 1 info` says:
The first non-option argument, if present, is the menu entry to
start from; it is searched for in all `dir' files along INFOPATH.
If it is not present, info merges all `dir' files and shows the
result. Any remaining arguments are treated as the names of menu
items relative to the initial node visited.
Which means that this does what previous programs/info did and #8519
(on-the-fly infodir generation for Emacs) wanted to do, but for both
programs.
In 14f09e0, I've introduced the module under modules/programs, because
the legacy virtualbox.nix was also under that path. But because we
already have modules/virtualisation/virtualbox-guest.nix, it really
makes sense to put this module alongside of it as well.
This module thus has no change in functionality and I've tested
evaluation against nixos/tests/virtualbox.nix and the manual.

My original reason to put it at the beginning of NIX_PATH was to allow
shipping a particular version <nixpkgs> with a channel. But in order to
do that, we can still let the channel expression ship with a custom
version of nixpkgs by something like <channel/nixpkgs> and the builder
of the channel could also rewrite self-references.
So the inconvenience is now shifted towards the maintainer of the
channel rather than the user (which isn't nice, but better err on the
side of the developer rather than on the user), because as @edolstra
pointed out: Having the channels of root at the beginning of NIX_PATH
could have unintended side-effects if there a channel called nixpkgs.

This is very useful if you want to distribute channels (and thus
expressions as well) in a similar fashion to Debians APT sources (or
PPAs or whatnot).
So, for example if you have a channel with some additional functions
or packages, you simply add that channel with:
sudo nix-channel --add https://example.com/my-nifty-channel foo
And you can access that channel using <foo>, for example in your
configuration.nix:
{
imports = [ <foo/modules/shiny-little-module> ];
environment.systemPackages = with import <foo/pkgs> {}; [ bar blah ];
services.udev.extraRules = import <foo/lib/udev/mkrule.nix> {
kernel = "eth*";
attr.address = "00:1D:60:B9:6D:4F";
name = "my_fast_network_card";
};
}
Within nixpkgs, we shouldn't have <nixos> used anywhere anymore, so we
shouldn't get into conflicts.

By making askPassword an option, desktop environment modules can
override the default x11_ssh_askpassword with their own equivalent for
better integration. For example, KDE 5 uses plasma5.ksshaskpass instead.
This was lost back in
ffedee6ed5. Getting this to work is
slightly tricky because ssh-agent runs as a user unit, and so doesn't
know the user's $DISPLAY.
This reverts commit 766207ca1d.
We need to solve the problem with `environment.profileRelativeEnvVars`.
The best workaround is to make profileRelativeEnvVars prepend paths.

IMHO, having a short timeout (1h) defeats the point of using
ssh-agent, which is not to have to retype passphrases all the time. Of
course, users who want timeouts can set programs.ssh.agentTimeout.
This restores the 14.04 behaviour.
Because we have to rely on setuid wrappers on NixOS, we can't easily
hardcode the executable paths and set it 4755. So for all calls, we need
to change the runtime path executable directory to /var/setuid-wrappers/
and for verification we need to retain the executable directory.
Also note, that usually VBoxNetAdpCtl, VBoxNetDHCP, VBoxNetNAT, VBoxSDL
and VBoxVolInfo don't reside in directories that are commonly in PATH,
but in /usr/lib/virtualbox in most mainstream distros. But because the
names of these executables are distinctive enough to not cause
collisions with other setuid programs, I'll leave it like that and not
patch up setuid-wrappers.

Fixes#5283.
Signed-off-by: aszlig <aszlig@redmoonstudios.org>
The current nixos module for VirtualBox unconditionally configures a vboxnet0
network interface at boot. This may be undesired, especially when the user wants
to manage network interfaces in a centralized manner.
VirtualBox with hardening support requires the main binaries to be
setuid root. Using VBOX_WITH_RUNPATH, we ensure that the RPATHs are
pointing to the libexec directory and we also need to unset
VBOX_WITH_ORIGIN to make sure that the build system is actually setting
those RPATHs.
The hardened.patch implements two things:
* Set the binary directory to the setuid-wrappers dir so that
VboxSVC calls them instead of the binaries from the store path. The
reason behind this is because nothing in the Nix store can have the
setuid flag.
* Excempt /nix/store from the group permission check, because while it
is group-writeable indeed it also has the sticky bit set (and also
the whole store is mounted read-only on most NixOS systems), so we're
checking on that as well.
Right now, the hardened.patch uses /nix/store and /var/setuid-wrappers
directly, so someone would ever want to change those on a NixOS system,
please provide a patch to set those paths on build time. However, for
simplicity, it's best to do it when we _really_ need it.

We will simply rename the previous module and add a warning whenever the
module is included directly, pointing the user to the right option and
also enable it as well (in case somebody has missed the option and is
wondering why VirtualBox doesn't work anymore).

NixOS has a pervasive dependency on bash. For instance, the X11
session script sources /etc/profile to get a reasonable
environment. Thus we should not provide an option to disable bash.
Also, enabling zsh no longer sets ‘users.defaultUserShell’ to zsh, to
prevent a collision with bash's definition of the same
option. (Changing the default shell is also something that should be
left to the user.)
This has some advantages:
* You get ssh-agent regardless of how you logged in. Previously it was
only started for X11 sessions.
* All sessions of a user share the same agent. So if you added a key
on tty1, it will also be available on tty2.
* Systemd will restart ssh-agent if it dies.
* $SSH_AUTH_SOCK now points to the /run/user/<uid> directory, which is
more secure than /tmp.
For bonus points, we should patch ssh-agent to support socket-based
activation...
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.
