2023-12-30login: T5875: restore home directory permissions when re-adding user accountChristian Breunig
After deleting a user account and working with a newly added account, we see that after rebooting in the previously saved configuration, the user is re-added but it's home directory might have an old UID set on the filesystem. This is due to the fact that vyos config does not store UIDs. When adding a user account to the system we now check if the home directory already exists and adjust the ownership to the new UID. (cherry picked from commit 3c990f49e2bf9347bd2cc478995baa995ee822fd)
2023-12-08login: T4943: use pam-auth-update to enable/disable Google authenticatorChristian Breunig
The initial version always enabled Google authenticator (2FA/MFA) support by hardcoding the PAM module for sshd and login. This change only enables the PAM module on demand if any use has 2FA/MFA configured. Enabling the module is done system wide via pam-auth-update by using a predefined template. Can be tested using: set system login user vyos authentication plaintext-password vyos set system login user vyos authentication otp key 'QY735IG5HDHBFHS5W7Y2A4EM274SMT3O' See https://docs.vyos.io/en/latest/configuration/system/login.html for additional details. (cherry picked from commit e134dc4171b051d0f98c7151ef32a347bc4f87e2)
2023-11-20TACACS: T5577: Added `mandatory` and `optional` modes for TACACS+zsdc
In CLI we can choose authentication logic: - `mandatory` - if TACACS+ answered with `REJECT`, authentication must be stopped and access denied immediately. - `optional` (default) - if TACACS+ answers with `REJECT`, authentication continues using the next module. In `mandatory` mode authentication will be stopped only if TACACS+ clearly answered that access should be denied (no user in TACACS+ database, wrong password, etc.). If TACACS+ is not available or other errors happen, it will be skipped and authentication will continue with the next module, like in `optional` mode.
2023-11-20RADIUS: T5577: Added `mandatory` and `optional` modes for RADIUSzsdc
In CLI we can choose authentication logic: - `mandatory` - if RADIUS answered with `Access-Reject`, authentication must be stopped and access denied immediately. - `optional` (default) - if RADIUS answers with `Access-Reject`, authentication continues using the next module. In `mandatory` mode authentication will be stopped only if RADIUS clearly answered that access should be denied (no user in RADIUS database, wrong password, etc.). If RADIUS is not available or other errors happen, it will be skipped and authentication will continue with the next module, like in `optional` mode.
2023-10-04Revert "login: T5521: home directory owner changed during reboot"Christian Breunig
This reverts commit 074870dad33d80e78128736f9e89bdfa1a0e08fd.
2023-10-03login: T5521: home directory owner changed during rebootChristian Breunig
During system startup the system-login.py script is invoked by vyos-router systemd service. As there is no complete configuration available at this point in time - and the sole purpose of this call is to reset/re-render the system NSS/PAM configs back to default - it accidently also deleted the local useraccounts. Once the VyOS configuration got mounted, users got recreated in alphabetical order and thus UIDs flipped and the /home suddenely belonged to a different account. This commit prevents any mangling with the local userdatabase during VyOS bootup phase. (cherry picked from commit 64d323299586da646ca847e78255ff2cd8464578)

This reverts commit 3a6e77d479da4321b851163490a9b79ef2cef7b8. A general solution is implemented in Commit 29a44a73 ("T4975: always sync() filesystem after commit").
2023-02-02login: T4975: Fixed broken CLI commandszsdc
User profile files are not saved to disk after configuration is fully applied. Because of this, after a fast system reset, profile files can be empty, and CLI is broken. This fix adds a `sync()` call after the user's configuration, which should protect from data loss and fix the problem with profiles.
2022-12-08T4790: Added check of the sum of radius timeoutsaapostoliuk
Added check of the sum of radius timeouts. It has to be less or eq 50 sec. Default LOGIN_TIMEOUT from /etc/login.defs minus 10 sec Added check of number of radius servers. It has to be less or eq 25. 50 sec divided by 2sec (minimum recomended login timeout) Otherwise, log in to the device can be descarded.

2021-09-02login: T3792: bugfix for usernames containing a hyphenChristian Poessinger
While migrating to get_config_dict() in commit e8a1c291b1 ("login: radius: T3192: migrate to get_config_dict()") the user-name was not excluded from mangling (no_tag_node_value_mangle=True). This resulted in a username "vyos-user" from CLI to be actually created as "vyos_user" on the system. This commit also adds respective Smoketests to prevent this in the future.
