mtcAgent process stops when console times out

[Michel Thebeau [WIND]]

Brief Description

After bootstrap the mtcAgent process does not persist of the console times out

Severity

Minor

Steps to Reproduce

Bootstrap a controller-0 using the console. After bootstrap watch the mtcAgent process in another shell, and set 'export TMOUT=10' on the console. When the console times out the mtcAgent will go away.

Expected Behavior

mtcAgent is not dependant on console

Actual Behavior

mtcAgent goes away when the console times out.

Reproducibility

Yes

System Configuration

Any, probably

Load info (eg: 2022-03-10_20-00-07)

Starlingx, November 17 and later

Last Pass

Uncertain. Maybe before: https://review.opendev.org/c/starlingx/config-files/+/861633)

Timestamp/Logs

Ten seconds after this bash log:
2022-11-17T23:22:09.000 localhost -sh: info HISTORY: PID=1871 UID=42425 export TMOUT=10

Alarms

fm alarm-list doesn't work

Test Activity

Generic, unrelated

Workaround

Do not let console time out after bootstrap and before unlock. Probably use "export TMOUT=99999999" before ansible bootstrap.

    in case of session timeout after bootstrap and before unlock. As a
    workaround, this change disables session timeout.

    https://review.opendev.org/c/starlingx/config-files/+/866211
    increases session timeout from 15min to 24h. In order to restore the
    default value, after unlock this change decreases back session timeout
    from 24h to 15min.

    Test Plan:
    [PASS] Install, bootstrap and unlock.
    [PASS] After unlock, verify TMOUT is set back to 900s (15min).

    Workaround for console session timeout terminating user processes

    The change https://review.opendev.org/c/starlingx/config-files/+/861633
    causes an unexpected behavior of systemd, terminating user processes
    in case of session timeout, between the moment after bootstrap and before unlock. As a workaround, this change removes pam_systemd.so from PAM common-session file during bootstrap, avoiding the issue and also performance degradation.

    Following changes must be reverted:
    https://review.opendev.org/c/starlingx/config-files/+/866211
    https://review.opendev.org/c/starlingx/stx-puppet/+/867098
    https://review.opendev.org/c/starlingx/config-files/+/861633

    Test Plan (Debian AIO-SX):
    [PASS] Install, bootstrap and unlock.
    [PASS] Verify "pam_systemd.so" config is removed after bootstrap.
    [PASS] Verify there is no extra "systemd --user" processes running in
    background.
    [PASS] Verify no issues occur in standard upgrade scenario or during runtime manifest apply.
