kldfind() only matches kernel modules, so if you link imgact_binmisc directly
into the kernel, binmiscctl can't find it, tries to load it, and errors
out with:
Can't load imgact_binmisc kernel module: File exists
A quick search of other base commands shows that the correct procedure is to
call modfind(), and then try kldload() if that fails.

This patch defines a macro that checks for MNTK_UNMOUNTF and replaces

This largely reverts FreeBSD SVN change 289937 from October 25th, 2015.
The intent of that change was to keep loop IDs persistent across
chip reinits.
The problem is that the change turned on the PREVLOOP /
PREV_ADDRESS bit (bit 7 in Firmware Options 2), which tells the
Qlogic chip to not participate in the loop if it can't get the
requested loop address. It also turned off soft addressing on 2400
(4Gb) and newer controllers.
The isp(4) driver defaults to loop address 0, and the tape drives
I have tested default to loop address 0 if hard addressing is turned
on. So when hard loop addressing is turned on on the drive, the isp(4)
driver just refuses to participate in the loop.
The solution is to largely revert that change. I left some elements
in place that are related to virtual ports, since they were new.
This does work with IBM tape drives with hard and soft addressing
turned on. I have tested it with 4Gb, 8Gb, and 16Gb controllers.
sys/dev/isp.c:
Largely revert FreeBSD SVN change 289937. I left the
ispmbox.h changes in place.
Don't use the PREV_ADDRESS bit on initialization. It tells
the chip to not participate if it can't get the requested
loop ID.
Do use soft addressing on 2400 and newer chips.
Use hard addressing when the user has requested a specific
initiator ID. (hint.isp.X.iid=N in /boot/loader.conf)
Leave some of the virtual port options from that change in
place, but don't turn on the PREV_ADDRESS bit.

Usually it is sufficient to use iicbus_transfer_excl(), or one of the
higher-level convenience functions that use it, to reserve the bus for the
duration of each register access. Occasionally it is important that a
series of accesses or read-modify-write operations must be done without any
other intervening access to the device, to prevent corrupting state.
Without support for nested request/release, slave device drivers would have
to stop using high-level convenience functions and resort to working with
arrays of iic_msg structs just for a few operations (often involving
one-time device setup or infrequent configuration changes).
The changes here appear large from a glance at the diff, but in fact they're
nearly trivial, and the large diff is because of changes in indentation and
the re-wrapping of comments caused by that. One notable change is that
iicbus_release_bus() now ignores the IICBUS_CALLBACK(IIC_RELEASE_BUS) return
value. The old error handling left the bus in a kind of limbo state where
it was still owned at the iicbus layer, but drivers rarely check the return
of the release call, and it's unclear what they would do to recover from an
error return anyway. No existing low-level drivers return any kind of error
from IIC_RELEASE_BUS except one EINVAL for "you don't own the bus", to which
the right response is probably to carry on with the process of releasing the
reference to the bus anyway.
on i2c devices, where the "register" can be any length.
Many (perhaps most) common i2c devices are organized as a collection of
(usually 1-byte-wide) registers, and are accessed by first writing a 1-byte
register index/offset number, then by reading or writing the data.
Generally there is an auto-increment feature so the when multiple bytes
are read or written, multiple contiguous registers are accessed.
Most existing slave device drivers allocate an array of iic_msg structures,
fill in all the transfer info, and invoke iicbus_transfer(). These new
functions commonize all that and reduce register access to a simple call
with a few arguments.
Suppose that a file on NFS has partially filled last page, and this
page is dirty. NFS VOP_PAGEOUT() method only marks the the page clean
up to the block of the last written byte, leaving other blocks dirty.
Also any page which erronously exists in the vnode vm_object past EOF
is also left marked as dirty.
With the introduction of the buf-cache coherent pager, each pass of
syncer over the object with such page results in creation of B_DELWRI
buffer due to VOP_WRITE() call. This buffer is noted on next syncer
pass, which results e.g. a visible manifestation of shutdown never
finishing vnode sync. Note that before buf-cache coherency commit, a
dirty page might left never synced to server if a partial writes
occur.
Fix this by clearing dirty bits after EOF. Only blocks of the partial
page which are completely after EOF are marked clean, to avoid
possible user data loss.

The CloudABI specification has had some minor changes over the last half
year. No substantial features have been added, but some features that
are deemed unnecessary in retrospect have been removed:
- mlock()/munlock():
These calls tend to be used for two different purposes: real-time
support and handling of sensitive (cryptographic) material that
shouldn't end up in swap. The former use case is out of scope for
CloudABI. The latter may also be handled by encrypting swap.
Removing this has the advantage that we no longer need to worry about
having resource limits put in place.
- SOCK_SEQPACKET:
Support for SOCK_SEQPACKET is rather inconsistent across various
operating systems. Some operating systems supported by CloudABI (e.g.,
macOS) don't support it at all. Considering that they are rarely used,
remove support for the time being.
- getsockname(), getpeername(), etc.:
A shortcoming of the sockets API is that it doesn't allow you to
create socket(pair)s, having fake socket addresses associated with
them. This makes it harder to test applications or transparently
forward (proxy) connections to them.
With CloudABI, we're slowly moving networking connectivity into a
separate daemon called Flower. In addition to passing around socket
file descriptors, this daemon provides address information in the form
of arbitrary string labels. There is thus no longer any need for
requesting socket address information from the kernel itself.
This change also updates consumers of the generated code accordingly.
Even though system calls end up getting renumbered, this won't cause any
problems in practice. CloudABI programs always call into the kernel
through a kernel-supplied vDSO that has the numbers updated as well.
