pam-ussh allows authorizing using an SSH certificate stored in your
SSH agent, in a similar manner to pam-ssh-agent-auth, but for
certificates rather than raw public keys.
When running e.g. `aa-genprof` get error:
> ERROR: Syntax Error: Unknown line found in file /etc/apparmor.d/abstractions/pam line 26:
> r /nix/store/XXXXX.pam,mr /nix/store/XXXXX-linux-pam-1.5.1/lib/security/pam_filter/*,
So add an explicit newline as concatMapStringsSep only adds them
between.
pam_mkhomedir should create homedirs with the same umask as the rest
of the system. Currently it creates homedirs with go+rx which makes
it readable for other non-privileged users.
nixos-rebuild test causes pam_mount to prompt for a password when running with
an encrypted home:
building '/nix/store/p6bflh7n5zy2dql8l45mix9qnzq65hbk-nixos-system-mildred-18.09.git.98592c5da79M.drv'...
activating the configuration...
setting up /etc...
reenter password for pam_mount:
(mount.c:68): Messages from underlying mount program:
(mount.c:72): crypt_activate_by_passphrase: File exists
(pam_mount.c:522): mount of /dev/mapper/vg0-lv_home_peter failed

This change makes pam_mount not prompt. It still tries to remount (and fails in
the process) but that message can be ignored.
Fixes: #44586
Currently if fprintd is enabled, pam will ask for fingerprint
regardless of other configured authentication modules (e.g. yubikey).
This change make fingerprint the last resort of authentication before asking for password.
For in NixOS it is beneficial if both plasma5 and pam use the same Qt5
version. Because the plasma5 desktop may use a different version as the
default Qt5 version, we introduce plasma5Packages.
This reverts commit fb6d63f3fd.
I really hope this finally fixes#99236: evaluation on Hydra.
This time I really did check basically the same commit on Hydra:
https://hydra.nixos.org/eval/1618011
Right now I don't have energy to find what exactly is wrong in the
commit, and it doesn't seem important in comparison to nixos-unstable
channel being stuck on a commit over one week old.
9544c6078e / #96672 removed the samba option
`syncPasswordsByPam`.
Need to remove this option from the pam module, otherwise it will cause build errors
This patch was done by curro:
The generated /etc/pam.d/* service files invoke the pam_systemd.so
session module before pam_mount.so, if both are enabled (e.g. via
security.pam.services.foo.startSession and
security.pam.services.foo.pamMount respectively).
This doesn't work in the most common scenario where the user's home
directory is stored in a pam-mounted encrypted volume (because systemd
will fail to access the user's systemd configuration).
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
In #68792 it was discovered that /dev/fuse doesn't have
wordl-read-writeable permissions anymore. The cause of this is that the
tmpfiles examples in systemd were reorganized and split into more files.
We thus lost some of the configuration we were depending on.
In this commit some of the new tmpfiles configuration that are
applicable to us are added which also makes wtmp/lastlog in the pam
module not necessary anymore.
Rationale for the new tmpfile configs:
- `journal-nowcow.conf`: Contains chattr +C for journald logs which
makes sense on copy-on-write filesystems like Btrfs. Other filesystems
shouldn't do anything funny when that flag is set.
- `static-nodes-permissions.conf`: Contains some permission overrides
for some device nodes like audio, loop, tun, fuse and kvm.
- `systemd-nspawn.conf`: Makes sure `/var/lib/machines` exists and old
snapshots are properly removed.
- `systemd-tmp.conf`: Removes systemd services related private tmp
folders and temporary coredump files.
- `var.conf`: Creates some useful directories in `/var` which we would
create anyway at some point. Also includes
`/var/log/{wtmp,btmp,lastlog}`.
Fixes#68792.
