variable length, so we should not be trying to copy it into a fixed
length buffer, especially one on the stack. malloc() a buffer of the
right size and return a pointer to that instead.
Fixes a crash I discovered when testing whe a Cisco AP in infrastructure
mode, which returns several information elements that make the
ndis_wlan_bssid_ex structure larger than expected.
Because xfer->send.payload is a pointer to the buffer, '&' shouldn't be there.

hostname, resolve, tmp, and var scripts. The latter three are new and
were repo copied. These scripts no longer depend on being booted with

volumes if the they are not writable. This behavior can be overridden
in /etc/rc.conf.

cause an endless loop when a map was loaded and DVMA was scarce,
or that map had a stringent alignment or boundary.

end of the stack (only the pc is checked in that case), which became
fatal when db_print_backtrace() was introduced and called outside

caused hangs on SMP systems under load. My theory was that an interrupted
thread was migrating and returning to PAL on a different CPU and that that
caused the hangs. To prevent this, I used the recently added sched_pin()
API to pin the interrupted thread to the CPU that received the interrupt
across ithread_schedule() to prevent migration. This seems to have fixed
the hangs based on tests by several folks on the alpha@ list.
Tested by: wilko, tisco, several others on alpha@
(NIC would claim to establish a link with an ad-hoc net but it couldn't
send/receive packets). It turns out that every time the checkforhang
handler was called by ndis_ticktask(), the driver would generate a new
media connect event. The NDIS spec says the checkforhang handler is
called "approximately every 2 seconds" but using exactly 2 seconds seems
too fast. Using 3 seconds makes it happy again, so we'll go with that
for now.
Fd_set and Sigaction structures. Use these for printing the arguments
to sigaction(), nanosleep(), select(), poll(), gettimeofday(),
clock_gettime(), recvfrom(), getitimer() and setitimer().
This is based on Dan's patch from the PR but I've hacked it for
style and some other issues. While Dan has checked this patch, any
goofs are probably my fault.
(The PR also contains support for the dual return values of pipe().
These will follow once I've ported that support to platforms other
than i386.)

just in case...)
merges, debug.mpsafenet will no longer be safe to use, and that it should

to UPDATING (and post to freebsd-current) when it's safe to turn it on,
with a description of under what circumstances it is safe to use.
- Add gre_mtx to protect global softc list.
- Hold gre_mtx over various list operations (insert, delete).
- Centralize if_gre interface teardown in gre_destroy(), and call this
from modevent unload and gre_clone_destroy().
- Export gre_mtx to ip_gre.c, which walks the gre list to look up gre
interfaces during encapsulation. Add a wonking comment on how we need
some sort of drain/reference count mechanism to keep gre references
alive while in use and simultaneous destroy.
This commit does not lockdown softc data, which follows in a future
commit.
- Add gif_mtx, which protects globals.
- Hold gif_mtx around manipulation of gif_softc_list.
- Abstract gif destruction code into gif_destroy(), which tears down
a softc after it's been removed from the global list by either module
unload or clone destroy.
- Lock gif_called, even though we know gif_called is broken with reentrant
network processing.
- Document an event ordering problem in gif_set_tunnel() that will need
to be fixed.

NO_POSIX_COMPAT was added in 1996 as attempt to resolve POSIX regex
functions conflict for fixit floppy (they are both in libc and libgnuregex)
The way it done (simple excluding POSIX functions from compile) breaks
legitimate case when, say, some program from ports calls both POSIX
and GNU regex functions (it will call POSIX ones from libc and fails,
because header <regex.h> is from GNU).
Now our fixit floppy (and other crunched floppies, as I check) not
use libgnuregex, so the hack can be removed.
processing with gif interfaces, to a global variable named "gif_called".
Add an annotation that this approach will not work with a reentrant
network stack, and that we should instead use packet tags to detect
excessive recursive processing.
exactly the same as patch from the PR, which also exited if the
config file was missing. I didn't use Jeff's patch because I was
worried that some people might start inetd, create the config file
and then HUP inetd.
