2021-04-13watchdog: make open-write-close-open functionality a config knobRasmus Villemoes
The behaviour introduced by commit 31c765081dc4 ("watchdog: stop watchdog first on startup") causes warnings in the kernel log when the nowayout feature is enabled: [ 16.212184] watchdog: watchdog0: nowayout prevents watchdog being stopped! [ 16.212196] watchdog: watchdog0: watchdog did not stop! The latter may also appear by itself in case the watchdog is of the type that cannot be stopped once started (e.g. the common always-running gpio_wdt kind). These warnings can be somewhat ominous and distracting, so allow configuring whether to use this open-write-close-open sequence rather than just open. Also saves a bit of .text when disabled: function old new delta shutdown_on_signal 31 58 +27 watchdog_main 339 306 -33 shutdown_watchdog 34 - -34 ------------------------------------------------------------------------------ (add/remove: 0/1 grow/shrink: 1/1 up/down: 27/-67) Total: -40 bytes Make it default n: - It's a workaround for one specific type of watchdog (and that seems to be a defect in the kernel driver) - Even when not enabled in busybox config, it can easily be implemented outside busybox - Code size - Commit 31c765081dc4 should be considered a regression for all the boards that now end up with KERN_CRIT warnings in dmesg. - The author of that commit said "This use case is evidently rare, so if it is indeed causing problems for other people I'd OK then I understand whatever needs to be done." in the v1 thread.

PLATFORM_LINUX is a hidden configuration option which is disabled by default and enabled at over a hundred locations for features that are deemed to be Linux specific. The only effect of PLATFORM_LINUX is to control compilation of libbb/match_fstype.c. This file is only needed by mount and umount.

2017-07-08watchdog: stop watchdog first on startupMatt Spinler
Some watchdog implementations may do things other than issue a reboot on a watchdog timeout. In this case, there's the possibility of restarting this program from the state of the watchdog device not being properly stopped (done by writing a 'V' and closing the device). Since it wasn't stopped, the driver may not be able to restart the watchdog when this program reopens it and starts pinging it. To fix this, the code will always first issue the stop when it starts up. function old new delta shutdown_on_signal - 32 +32 watchdog_main 268 298 +30 shutdown_watchdog - 25 +25 watchdog_shutdown 41 - -41 ------------------------------------------------------------------------------ (add/remove: 2/1 grow/shrink: 1/0 up/down: 87/-41) Total: 46 bytes Signed-off-by: Matt Spinler <spinler@us.ibm.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2012-12-19CONFIG_PID_FILE_PATH: new configuration option for pidfile pathsAnthony G. Basile
We set a default path for the directory where pidfiles are create when FEATURE_PIDFILE is selected. The default has no effect on applets which must specify a pidfile path on the command line to run, and it can be overridden by applets which optionally allow the user to specify the pidfile path. We also add pidfile write/remove support for klogd, ntpd and watchdog. For syslogd, we add a missing remove_pidfile() for better cleanup on daemon exit. Signed-off-by: Anthony G.
