* Always use /proc/sys/kernel/random/boot_id to confirm reboot on Linux
/proc/sys/kernel/random/boot_id is available since kernel 2.3.16 and
should be safe to rely on.
The previously used method by checking the system boot time using who -b
turned out to be unreliable: Some systems lacking an RTC report the Unix
epoch as boot time, but the code trying to detect that did't always
work.
Closes#46562
* Change DEFAULT_BOOT_TIME_COMMAND
- change to usinsg /proc by default
- add BOOT_TIME_COMMANDS for BSD, Solaris, and macOS
* reboot: Add timeout in error to help troubleshooting
So we've been hit by 'Timed out waiting for boot_time check' and it was
unclear what timeout was used for the boot_time check. By adding the
timeout value it is easier to understand the used value, and verify if a
change to the timeout is reflected in the output.
* Add changelog fragment
* win_reboot: Fix for ignore post_reboot_delay
This fixes an issue where win_reboot would be ignoring the provided
post_reboot_delay (and on Windows timing/waiting is everything!)
This must be backported to the v2.7 branch.
* Merge post-reboot handling into run()
The stdout and stderr values returned from self._low_level_execute() are text, not bytes. This results in an error in Python 3 since str and bytes cannot be concatenated.
Changing to unicode type allows this to work without error on Python 2 and Python 3.
* reboot: Fix typo and support bare Linux systems
This fixes a problem for bare Linux systems that do not support 'who -b' or 'uptime -s'.
* Accumulate stdout and stderr information
* Update docs
* Add reboot action plugin
Refactor win_reboot so it is subclassed from reboot
* Use new connection methods
* Test fixes
* Use better uptime command for Linux
Use who -b to get the last time the system was booted rather than uptime, which changes every second.
* Use distribution specefic commands and flags
Query the managed node to determien its distribution, then set the appropriate command and flags.
* Tune debug messages a bit
* Update module docs with details about pre_reboot_delay
s docs
* Ensure that post_reboot_delay is a positive number
* Remove the stringification
* Add integration tests
* Make sure aliases are honored
* Handle systems that have an incorrect last boot time
SystemD and fakehw-clock do not properly set the
last boot time and instead always set it to epoch.
Use a different command if that is the case.
* Copyright and encoding fixes
* Minor fixes based on feedback
* Add exponential backoff to sucess check method
* Update integration test
Skip the integration test if it would try to reboot the control node. We need a new mechanism to account for this scenario in ansible-test, so tests must currently be run manually for this plugin.
