d2d975246d Kernel sends SIGKSTOP just before shutdown. Drivers do clean up and exit. 2005-07-20 15:28:05 +00:00

f1153541c7 Fixed bug in PM that caused update program not to be scheduled, so that 
sync was not periodically run. Chain of timers was accidentially broken.

Kernel sends SIGKSTOP signal on shutdown. FS calls sync to clean up.

0129d98ae1 Added new signal types for kernel events: 
- SIGKMESS: new kernel message (sent to TTY, IS, or LOG)
- SIGKSTOP: MINIX is shut down (sent to TTY-> switch to primary console)
- SIGKSIG: kernel signals pending (sent to PM)

Renamed SYS_SETPRIORITY to SYS_NICE.

198c976f7e System processes can be signaled; signals are transformed in SYS_EVENT message 
that passes signal map along. This mechanisms is also used for nonuser signals
like SIGKMESS, SIGKSTOP, SIGKSIG.

Revised comments of many system call handlers. Renamed setpriority to nice.

eba45510a9 New alarm(2) timers mechanism. 
Kernel no longer keeps track of user alarms on behalf of the PM.
Instead, the PM maintains its own list of watchdog timers, and
uses one synchronous alarm (at the kernel) to get notifications
for expired user timers.

c389801a5f Made timeout and no. of errors in at_wini dynamically settable 
by ioctl; made catch-all function in driver table also called when
unrecognized ioctl called, so drivers can add their own ioctl codes.

f96645a4eb Fixed a bug in kstrncpy() that caused mayhem whenever the buffer to be 
copied into was the same size as the source string - it will keep on
filling with zeroes forever. This was a signed/unsigned bug, fixed by
making the kstrncpy argument ssize_t instead of size_t. This bug was
triggered by Chris Young <teddga@earthlink.net>, by dazzling coincedence -
changing OS_VERSION into something with one more character (exactly the
same size as the buffer in the kinfo struct).

Also noticed that the kstrncpy() call didn't null-terminate the strings
if necessary, also fixed.
