For example, when /etc/pccard.conf had ed0 in config line, but kernel
refused this name and said
devclass_alloc_unit: ed0 already exists, using next availale unit
number
Kernel used ed1 as device name and it did not match with config and
insert/remove lines. Fortunately, dhclient was called without args,
and it works, but if we wanted to use static IP address for PC-card,
it did not work.
This modification makes pccardd to execute insert/remove lines with
the true device name that returns from kernel. (Last change to
etc/pccard.conf.sample eliminated all hardwired device name from
insert/remove lines in /etc/pccard.conf)

Removed all other trailing semicolons in macro definitions. The
ones after `do ... while (0)' wrappers defeated the point of the

Enforce semicolons after invocation of declaration-like macros.

Note that the sticker on the bottom of the adapter says amber for 10

seem to be any way to make the hardware produce the latter combination,

of 4 longs used as a bitmask. sv4r4_sigfillset has been broken for a
while, probably since rev 1.5.
This patch fixes SVR4_NSIG (i.e.: sets it to the actual number of signals,
instead of the number of bits in the mask) because some SysVR4 clients
honestly seem to care about whether bits in the signal mask are set for
non-existant signals.
Additionally, the svr4_sigfillset macro has been replaced by a
fully fledged function, because the macro didn't actually work
(it returned an all-ones mask, but we don't want that: we want 0's
set where FreeBSD doesn't actually have a signal which is the same
as an SysVR4 signal, for example).
SysVR4 clients can now successfully ignore signals, although catching
them remains problematic (see commit log message for rev1.13 of
sys/i386/svr4/svr4_machdep.c for more info).
eliminate warnings, etc.
Note that svr4_setcontext() and svr4_getcontext() currently don't work
correctly, which makes returning from signal handlers somewhat problematic
(for reference: the SysVR4 setcontext() and getcontext() syscalls behave
like a low-level version of setjmp() and longjmp(), in that they save and
restore process context. SysVR4 uses this to implement its signal handler
trampoline: The context which is saved before a signal handler is called
is restored by an implicit call to the setcontext() syscall when the signal
handler returns. That currently doesn't work right in this emulator,
although it used to).
I'm committing this anyway, with a caveat that it's buggy, so that I can
(a) note the bug for anyone who is wondering about it, and (b) get the
stuff I've done to improve (but not fix) the situation in the tree before
4.0 is released. If I have time to fix it totally RSN I'll talk to Jordan
to see if I can bend him into letting me commit a bugfix :-)
Note that the situation now is somewhat better than it was yesterday
anyway, because I've fixed the handling of svr4_sigsets which previously
was causing signal handlers to not get called at all. Stay tuned for
an upcoming commit to svr4_signal.c...
- Split terminal emulation code from the main part of the driver so
that we can have alternative terminal emulator modules if we like in
the future. (We are not quite there yet, though.)
- Put sysmouse related code in a separate file, thus, simplifying the
main part of the driver.
As some files are added to the source tree, you need to run config(8)
before you compile a new kernel next time.
You shouldn't see any functional change by this commit; this is only
internal code reorganization.

Pleases let me make sure that no one touch the invalid ro_rt pointer,
after splx(s) and before next ro_rt initialization.
Though usually this seems to be already called at splnet,
I still sometime experience kernel crash at rtfree() in my
INET6 enabled environment where IPv6 connection is frequently used.
(Off-course, it might be just due to another bug.)
This must be one of the reason why connections over IPsec hangs for
bigger packets.(which was reported on freebsd-current@freebsd.org)
But there still seems to be another bug and the problem is not yet fixed.
ifconfig and bogus ethernet address (4b:57:4b:57:4b:57) has been
