the same code as the VIDBUF8 case, so it only worked for depths <= 8.
The 2 directions for copying between VIDBUFs and MEMBUFs worked by using
a Read/Write organization which makes the destination a VIDBUF so the
MEMBUF case was not reached, and the VIDBUF cases have already been fixed.
Fix this by removing "optimizations" for the VIDBUF8 case so that the
MEMBUF case can fall through to the general (non-segmented) case. The
optimizations were to duplicate code for the VIDBUF8 case so as to
avoid 2 multiplications by 1 at runtime. This optimization is not useful
since the multiplications are not in the inner loop.
Remove the same "optimization" for the VIDBUF8S case. It was even less
useful there since it duplicated more to do relatively less.
All variable assignments that start in column 1 have to be on a single
line for amd to build due to as weird dependency there (most likely it
can be fixed to use the new VARS_ONLY feature, but it isn't
today). usr.sbin/amd/include/Makefile calls
usr.sbin/amd/include/newvers.sh which does:
eval `LC_ALL=C egrep '^[A-Z]+=' $1 | grep -v COPYRIGHT`
which is where that requirement comes from. It handles COPYRIGHT since
that's an exception. Rather than add additional exceptions, cope with
the long line in newvers.sh instead. Note: it no longer needs to
filter COPYRIGHT because the assignment doesn't start in column 1
anymore.
I had done a universe when I had an earlier version of r346018 that
had it as one line. When I changed it to multi-line as suggested in
the review, I only built kernels on a couple of architectures to make
sure it didn't break anything.
Add comment to newvers.sh noting this.
Obviously, this unbreaks the amd build.
In certain scenarios, it is possible for PCPU data to be
accessed before it has been initialized (e.g. during printf
if the kernel was built with the TSLOG option).
Initialize the PCPU pointer for hart 0 at the beginning of
initriscv() rather than near the end.

346002 did miss the fact that we do not only undo the loadaddr, but also
we need to remove the inserted module. Implement file_remove() to do the job.

The last_file variable is used to reset the loadaddr variable back to original
value; however, it is possible the last_file is NULL, so we can not blindly
trust it. But then again, we can just save the original loadaddr and use

are enabled.
The nfsuserd(8) daemon does not function correctly when jails are enabled,
since localhost gets mapped to another IP address and, as such, the upcall
RPC fails.
This patch fixes the problem by doing a getsockname(2) of a socket mapped
to localhost to find out what the correct address is for the comparison
test with the upcall's from IP address.
This patch also adds INET6 support and the required #ifdef's for INET and
INET6. It now uses INET6 by default for the upcalls, if the kernel has
INET6 support and the daemon is also built with INET6 support.

The kernel code uses UDP to do upcalls to the nfsuserd(8) daemon to get

A change to AF_LOCAL last year had to be reverted, since it could result

* The BIO bio_data may not be page aligned. Only the base address of each
page worth of data is extracted to pass to OPAL. Without page alignment
it can scribble over random memory when finishing the page read. Fix this
by short-reading the first page to properly align for full page reads.
* Fix the definition of OPAL_FLASH_ERASE.
* Properly handle the async message result, as now returned from r345974.

ifconfig(8) syntax allows to specify only single address_family,
so we need additional invocation of ifconfig to support configuration
of cloned gif interface that may use different address families
for its internal and external addresses.
Also, ifconfig(8) does not allow to omit "inet6" keyword for address family
specifying IPv6 addresses as outer addresses of the interface.
Also, address_family is not "parameter" and it has to go before parameters
including "tunnel" keyword, so "ifconfig gif0 tunnel inet6 $oip1 $oip2" would be
wrong syntax and only "ifconfig gif0 inet6 tunnel $oip1 $oip2" is right.
With this change, the following works:
gifconfig_gif0="inet6 2a00::1 2a01::1"
ifconfig_gif0="inet 10.0.0.1 10.0.0.2 netmask 255.255.255.252"

bhyve's NVMe emulation was transferring Identify data back to the guest
incorrectly causing memory corruptions. These corruptions resulted in
core dumps and other system level errors in the guest.
In their simplest form, NVMe Physical Region Page (PRP) values in
commands indicate which physical pages to use for data transfer. The
first PRP value is not required to be page aligned but does not cross a
page boundary. The second PRP value must be page aligned, does not cross
a page boundary, and need not be contiguous with PRP1.
The code was copying Identify data past the end of PRP1. This happens to
work if PRP1 and PRP2 are physically contiguous but will corrupt guest
memory in unpredictable ways if they are not.
Fix is to copy the Identify data back to the guest piecewise (i.e. for
each PRP entry). Also fix a similarly wrong problem when copying back
Log page data.

The NVMe specification defines bits 13:4 of BAR0 as Reserved (i.e. 0x0).
Most drivers do not enforce this, but the Windows NVMe driver does and
will refuse to start the device (i.e. error 10) if any of these bits are
set.
The current BAR size calculation tries to minimize the amount of memory
the device reserves by scaling the BAR size by the maximum number of
queues supported by the device. But unless the device supports a large
number of queue pairs (over 1536), it will reserve too little memory.
The fix is to allocate a minimum of 16K bytes for BAR0.
