EVFILT_WRITE knotes for pipes live on the knlist for the other end of the
pipe. Since they do not hold a reference on the corresponding file
structure, they may be removed from the knlist by pipeclose() while still
remaining active. In this case, there is no knlist lock acquired before
filt_pipewrite() is called, so the assertion fails.
Fix the problem by first checking whether that end of the pipe has been
closed. These checks are memory safe since the knote holds a reference
on one end of the pipe, and the pipe structure is not freed until both
ends are closed. The checks are not racy since PIPE_EOF is never cleared
after being set, and pipe_present is never set back to PIPE_ACTIVE after
pipeclose() has been called.

that can happen when rerooting into NFSv4 rootfs with kernel
built with INVARIANTS.
I've talked to rmacklem@ (back in 2017), and while the root cause
is still unknown, the case guarded by assertion (nfscl_doclose()
being called from VOP_INACTIVE) is believed to be safe, and the
whole thing seems to run just fine.

way: device<unit>[s|p]<slice><partition>. E.g., disk0s2a or disk3p12.
The code first tries to parse the variable in this format using the
standard disk_parsedev(). If that fails, it falls back to parsing the
legacy format that has been supported by ubldr for years.
In addition to 'disk', all the valid uboot device names can also be used:
mmc, sata, usb, ide, scsi. The 'disk' device serves as an alias for all
those types and will match the Nth storage-type device found (where N is
the unit number).
The pmap_works variable is always true for amd64. Remove it, the
branch in the initialization taken when false, and corresponding

This change adds a counter (kqueue_users) to keep track of how many
kqueue users are referencing a given struct nm_selinfo.
In this way, nm_os_selwakeup() can schedule the kevent notification
task only when kqueue is actually being used.
This is important to avoid wasting CPU in the common case where

loaderdev variable works correctly.
The uboot_devdesc struct is variously cast back and forth between
uboot_devdesc and disk_devdesc as pointers are handed off through various
opaque interfaces. uboot_devdesc attempted to mimic the layout of
disk_devdesc by having a devdesc struct, followed by a union of some
device-specific stuff that included a struct that contains the same fields
as a disk_devdesc. However, one of those fields inside the struct is 64-bit
which causes the entire union to be 64-bit aligned -- 32 bits of padding
is added between the struct devdesc and the union, so the whole mess ends
up NOT properly mimicking a disk_devdesc after all. (In disk_devdesc there
is also 32 bits of padding, but it shows up immediately before the d_offset
field, rather than before the whole collection of d_* fields.)
This fixes the problem by using an anonymous union to overlay the devdesc
field uboot network devices need with the disk_devdesc that uboot storage
devices need. This is a different solution than the one contributed with
the PR (so if anything goes wrong, the blame goes to me), but 95% of the
credit for this fix goes to Pawel Worach and Manuel Stuhn who analyzed the
problem and proposed a fix.

This was previously an unconditional screen clear, regardless of whether or
not we would be prompting for any passwords. This is pointless, given that
the screen clear is only there to put our screen into a consistent state
before we draw the prompts and do cursor manipulation.
This is also the only screen clear besides that to draw the menu. One can
now see early pre-loader and loader output with the menu disabled, which may
be useful for diagnostics.

I'm pretty sure this used to work at one time, perhaps long ago. It has
been failing recently because if you call disk_open() with dev->d_partition
set to -1 when d_slice refers to a bsd slice, it assumes you want it to
open the first partition within that slice. When you then pass that open
dev instance to ptable_open(), it tries to read the start of the 'a'
partition and decides there is no recognizable partition type there.
This restores the old functionality by resetting d_offset to the start
of the raw slice after disk_open() returns. For good measure, d_partition
is also set back to -1, although that doesn't currently affect anything.
I would have preferred to make disk_open() avoid such rude assumptions and
if you ask for partition -1 you get the raw slice. But the commit history
shows that someone already did that once (r239058), and had to revert it
(r239232), so I didn't even try to go down that road.
In r343986 we introduced a double free. The structure was already
