- Add the possibility to reuse the already last used timeout when patting the watchdog, via the watchdog(9) interface. - Add the possibility to pat the watchdogs installed via the watchdog(9) interface from the kernel. - Avoid to pass WD_ACTIVE down in the watchdog handlers. All the control bit processing should over to the upper layer functions and not passed down to the handlers at all. - Add the watchdogs patting during the (shutdown time) disk syncing and disk dumping.

MFC r218825. [The implementation change to kdb_sysctl_available()

2011-03-25T18:16:36Z

cannot be MFC'd as it requires a non-MFCable change (adding drains to sbuf)]. Modify kdb_trap() so that it re-calls the dbbe_trap function as long as the debugger back-end has changed. This means that switching from ddb to gdb no longer requires a "step" which can be dangerous on an already-crashed kernel. Also add a capability to get from the gdb back-end back to ddb, by typing ^C in the console window. While here, simplify kdb_sysctl_available() by using sbuf_new_for_sysctl(), and use strlcpy() instead of strncpy() since the strlcpy semantic is desired.

MFp4 @178364: Implement an optional delay to the ddb reset/reboot command. This allows textdumps to be run automatically with unattended reboots after a resonable timeout, while still permitting an administrator to break into debugger if attached to the console at the time of the event for further debugging. Cap the maximum delay at 1 week to avoid highly accidental results, and default to 15s in case of problems parsing the timeout value. Move hex2dec helper function from db_thread.c to db_command.c to make it generally available and prefix it with a "db_" to avoid namespace collisions. Reviewed by: rwatson

- Change the db_printf return value in order to catch up with printf - Make witness_list_locks() and witness_display_spinlock() accept callbacks for printf-like functions in order to queue the output on the correct channel.
