the handler with SA_RESTART set, so the system calls I wanted to have the
timeout effect will just restart instead (which is NOT what I wanted).
Sheepishly use sigaction() like a good boy and make timeouts actually do
something.
Also pass errors out more effectively so that fetch(1) actually understands
what went wrong.
it DTRT. In the process, discover the usual 10-15 evil bogons which
have been lurking in it for years. This closes, for one thing, the
recent report Mike Smith made about nested checklist menus returning
with the scrolling region messed up.
- Use MAP_FAILED instead of the constant -1 to indicate
failure (required by POSIX).
- Removed flag arguments of '0' (required by POSIX).
- Fixed code which expected an error return of 0.
- Fixed code which thought any address with the high bit set
was an error.
- Check for failure where no checks were present.
Discussed with: bde
called early for console i/o. The timer is usually in BIOS mode
if it isn't explicitly initialized. Then it counts twice as fast
and has a max count of 65535 instead of 11932. The larger count
tended to cause infinite loops for delays of > 20 us. Such delays
are rare. For syscons and kbdio, DELAY() is only called early
enough to matter for ddb input after booting with -d, and the delay
is too small to matter (and too small to be correct) except in the
PC98 case. For pcvt, DELAY() is not used for small delays (pcvt
uses its own broken routine instead of the standard broken one),
but some versions call DELAY() with a large arg when they unnecessarily
initialize the keyboard for doing console output. The problem is
more serious for pcvt because there is always some early console
output.
Guard against the i8254 timer being partially or incorrectly
initialized. This would have prevented the endless loop.
Should be in 2.2.
on it.
makesyscalls.sh:
This parsed $Id$. Fixed(?) to parse $FreeBSD$. The output is wrong when
the id is not expanded in the source file.
syscalls.master:
Fixed declaration of sigsuspend(). There are still some bogons and
spam involving sigset_t.
Use `struct foo *' instead of the equivalent `foo_t *' for some nfs and
lfs syscalls so that <sys/sysproto.h> doesn't depend on <sys/mount.h>.
variable `kern.maxvnodes' which gives much better control over vnode
allocation than EXTRAVNODES (except in -current between 1995/10/28 and
1996/11/12, kern.maxvnodes was read-only and thus useless).
I have no idea if this works since I don't have one of the cards to test.
I also don't know what the LINT and GENERIC entries should look like,
so I just made up some values for now and left them commented out.
Someone who knows the factory settings for a Pro/10, please contact me!

going into SLIP mode, useful for scripts that can automatically
grok IP addresses ala Trumpet Winsock.
