was never technically true (it's snp(4) that required root, not
watch(8)), and after snp.c 1.64, isn't even effectively true, since
who can run watch(8) depends on the permissions of the snp device(s).
Sort options in SYNOPSIS and DESCRIPTION while I'm here.
Previously, watch would always use the first device it could
successfully open, but this isn't always desired. Specifically, it
may not be desired during debugging (of snp), or if a particular snp
device has different permissions (which makes since after snp.c 1.64).
snooped on. This causes all kinds of Bad Things(tm) to happen since
closing one session will clobber state that's needed for the other
one. This could theoretically be supported if the code was careful,
but until somebody implements that, preventing this will stop people
from unknowingly shooting themselves in the foot.
device cloned, and assign all further devices to depend on it. This
allows us to call dev_depends() on it at module unload time to get rid
of /dev/snp* (in the devfs case, anyway). For this to work, we must
not destroy the device at close time. [Idea stolen from if_tun.]
The above has the following sideaffects: (a) The snp device used by
watch(8) will remain after watch(8) exits. This is probably how it
should have been all along, and how it was before devfs came along.
(b) Module unload doesn't panic if there are any /dev/snp* devices
which haven't been used (and thus previously destroyed). Thus, we can
reenable the unload functionality disabled in rev. 1.65.

Patch sent by David E. O'Brien, approved by maintainer.
- Fix an endianization error of a bus physical address used from SCRIPTS
that made the driver fail on big endian machines as sparc64.
The kernel certainly doesn't use _PATH_DEV or even /dev/ to find the device.
It cannot, since "/" has not been mounted. Maybe the only affect of using
/dev/ is that it gets put in the mounted-from name for "/", so that mount(8),
etc., display an absolute path before "/" has been remounted. Many have
never bothered typing the full path, and code that constructs a path in
rootdevnames[] never bothered to construct a full path, so the example
shouldn't have it.

cameras. The quirk enables translation from the C-1 signature to
the normal CSWSIGNATURE value.

This is a no-op on i386 and probably on alphas, as we currently

The OpenBSD PF_ROUTE/NET_RT_DUMP sysctl is sending back routes with
RTAX_NETMASK set, but the corresponding sockaddr being 4 zero bytes
(with an address family of zero). ppp was getting confused by this
and ending up interpreting it as a 0.0.0.0/32 routing table
destination and subsequently failing to do anything with the route.
Specifically, after this fix, ppp under OpenBSD can successfully
change and delete the default route again !

Don't write() the netmask for IPv6 sockaddrs to the routing socket if

It seems that messages written to the routing socket with the scopeid
set for link local addresses are not understood. Instead, we have to
put the scopeid in the 5th and 6th bytes of the address (see
adjust_linklocal() in ncpaddr.c). I think this may be a bug in the
KAME implementation - it should really understand both forms.

This file is now generated using src/tools/tools/pciid/mk_pci_vendors.pl,
which merges the Boemler and Heckenbach lists used for rev 1.2.
For now, mk_pci_vendors.pl is called with the -l option, which uses
the entry with the longer description where the same device or vendor
is found in both lists.
If it turns out that this causes to much "back-and-forth" in future
deltas, we can drop the use of the -l option.
