Klemens Nanni 8833983f26 nixos/users-groups: createHome: Ensure HOME permissions, fix description
configuration.nix(1) states

    users.extraUsers.<name>.createHome
        [...] If [...] the home directory already exists but is not
        owned by the user, directory owner and group will be changed to
        match the user.

i.e. ownership would change only if the user mismatched;  the code
however ignores the owner, it is sufficient to enable `createHome`:

    if ($u->{createHome}) {
        make_path($u->{home}, { mode => 0700 }) if ! -e $u->{home};
        chown $u->{uid}, $u->{gid}, $u->{home};
    }

Furthermore, permissions are ignored on already existing directories and
therefore may allow others to read private data eventually.

Given that createHome already acts as switch to not only create but
effectively own the home directory, manage permissions in the same
manner to ensure the intended default and cover all primary attributes.

Avoid yet another configuration option to have administrators make a
clear and simple choice between securely managing home directories
and optionally defering management to own code (taking care of custom
location, ownership, mode, extended attributes, etc.).

While here, simplify and thereby fix misleading documentation.

David Reiss 49a749c729 nixos/pam_mount: add pamMount attribute to users
This attribute is a generalized version of cryptHomeLuks for creating an
entry in /etc/security/pam_mount.conf.xml. It lets the configuration
control all the attributes of the <volume> entry, instead of just the
path. The default path remains the value of cryptHomeLuks, for
compatibility.

nixos.users-groups: Set up subuid/subgid mappings for all normal users
This is required by (among others) Podman to run containers in rootless mode.

Other distributions such as Fedora and Ubuntu already set up these mappings.

The scheme with a start UID/GID offset starting at 100000 and increasing in 65536 increments is copied from Fedora.

nixos/users-groups: remove ancient security.initialRootPassword option
This option has been deprecated for a long time because is redundant
(users.users.root.initialHashedPassword exists).
Moreover, being of type string, it required to handle the special value
"!" separately, instead of using just `null`.

nixos/treewide: Move rename.nix imports to their respective modules
A centralized list for these renames is not good because:
- It breaks disabledModules for modules that have a rename defined
- Adding/removing renames for a module means having to find them in the
central file
- Merge conflicts due to multiple people editing the central file

Increase max group name length to 32 characters
With #36556, a check was introduced to make sure the user and group
names do not exceed their respective maximum length. This is in part
because systemd also enforces that length, but only at runtime.

So in general it's a good idea to catch as much as we can during
evaluation time, however the maximum length of the group name was set to
16 characters according groupadd(8).

The maximum length of the group names however is a compile-time option
and even systemd allows more than 16 characters. In the mentioned pull
request (#36556) there was already a report that this has broken
evaluation for people out there.

I have also checked what other distributions are doing and they set the
length to either 31 characters or 32 characters, the latter being more
common.

Unfortunately there is a difference between the maximum length enforced
by the shadow package and systemd, both for user name lengths and group
name lengths. However, systemd enforces both length to have a maximum of
31 characters and I'm not sure if this is intended or just a off-by-one
error in systemd.

Nevertheless, I choose 32 characters simply to bring it in par with the
maximum user name length.

For the NixOS assertion however, I use a maximum length of 31 to make
sure that nobody accidentally creates services that contain group names
that systemd considers invalid because of a length of 32 characters.

nixos: remove the grsecurity GID
This GID was used to exempt users from Grsecurity's
`/proc` restrictions; we now prefer to rely on
`security.hideProcessInformation`, which uses the `proc` group
for this purpose.  That leaves no use for the grsecurity GID.

More generally, having only a single GID to, presumably, serve as the
default for all of grsecurity's GID based exemption/resriction schemes
would be problematic in any event, so if we decide to enable those
grsecurity features in the future, more specific GIDs should be added.

Eelco Dolstra 5f077e2296 Factor out option renaming
Option aliases/deprecations can now be declared in any NixOS module,
not just in nixos/modules/rename.nix. This is more modular (since it
allows for example grub-related aliases to be declared in the grub
module), and allows aliases outside of NixOS (e.g. in NixOps modules).

The syntax is a bit funky. Ideally we'd have something like:

  options = {
    foo.bar.newOption = mkOption { ... };
    foo.bar.oldOption = mkAliasOption [ "foo" "bar" "newOption" ];
  };

but that's not possible because options cannot define values in
*other* options - you need to have a "config" for that. So instead we
have functions that return a *module*: mkRemovedOptionModule,
mkRenamedOptionModule and mkAliasOptionModule. These can be used via
"imports", e.g.

  imports = [
    (mkAliasOptionModule [ "foo" "bar" "oldOption" ] [ "foo" "bar" "newOption" ]);
  ];

As an added bonus, deprecation warnings now show the file name of the
offending module.

Fixes #10385.
