opening a device, devfs_open needs the file descriptor to install its
own fileops. Failing to pass the file descriptor causes the vnode to
be returned with the regular vnops, which will cause a panic on the
first read or write because devfs_specops is not meant to support
those operations.
This bug caused a panic after exec'ing any set[ug]id program with
fds 0..2 closed (i.e., if any action had to be taken by fdcheckstd, we
would panic if the exec'd program ever tried to use any of those
descriptors).

a problem with one particular switch module. Create a kernel option
BGE_FAKE_AUTONEG that restores the 5.4 behavior, which should make the DNLK
switch module work. IBM/Intel blades with Intel or AD switch modules should
work without patching or kernel options with this commit.
Hardware for testing provided by several folks, including
Danny Braniss <danny@cs.huji.ac.il>, Achim Patzner <ap@bnc.net>,

exec_copyin_strings() to catch up to rev 1.266 of kern_exec.c. This fixes
panics on amd64 with compat binaries since exec_free_args() was freeing
more memory than these functions were allocating and the mismatch could
cause memory to be freed out from under other concurrent execs.

Without this patch, RELENG_5 and HEAD panics with something like:

RELENG_4 doesn't panic but spews following errors:

buffer would be to be after kvm_close(), but we don't do that yet. A
static buffer would work too.

OpenBSD has done with this file. It matches the copyright in NetBSD's
1.1 through 1.14 versions of the file as well, which they subsequently
added back.
It appears to have been lost in the 4.4-lite1 import for FreeBSD 2.0,
but where and why I've not investigated further. OpenBSD had the same
problem. NetBSD had a copyright notice until Multicast 3.5 was
integrated verbatim back in 1995. This appears to be the version that
made it into 4.4-lite1.

without reading the device tree from the kernel thinking that the cached
state was up to date since the generation count was the same. However,
since the cached state was actually free'd, attempts to examine the tree
after the second devinfo_init() would fail.
