The core kernel part is patch file utimes.2008.4.diff from
pluknet@FreeBSD.org. I updated the code for API changes, added the manual
page and added compatibility code for old kernels. There is also audit and
Capsicum support.
A new UTIME_* constant might allow setting birthtimes in future.

not removed or truncated to a zero-size file, which
if used to create more than one disk image format, can
result in accidental pollution of the target formatted
disk image.
Instead of using a single VMBASE image (vm.img, by
default), use a single base file for each format, named
as VMFORMAT.img, which produces VMBASE.VMFORMAT as the
final formatted image.

According to config(5), the "device", "devices",
"nodevice", "nodevices", "option", "options",
"nooption", and "nooptions" keywords can all take a
comma-separated list of values. However, the yacc code
did not allow lists for "nooption" and "nooptions", only
single values. This commit fixes the yacc code to allow
comma separated values for all the above keywords.

A "size" symbol with its address set to the length of handler would be
shifted forward with all other addresses when relocations are processed.
Instead, just note the end and do the subtraction at runtime.
in bitfield argument is wrong, as it will be treated as bit 10, causing any
code printing >=10 bits with bit 10 on as having a trailing comma.
Newline (intended one) should be part of the format string (already present
in the examples).
Also fix grammar and kill EOL whitespace in comment while here.

I edited the original change to retain the use of arc4random() as a seed for
the hashing as a very basic defense against intentional lagg port selection.
The author's original commit message (edited slightly):
sys/net/ieee8023ad_lacp.c
sys/net/if_lagg.c
In lagg_hashmbuf, use the FNV hash instead of the old
hash32_buf. The hash32 family of functions operate one octet
at a time, and when run on a string s of length n, their output
is equivalent to :
----- i=n-1
\
n \ (n-i-1) 32
( seed^ + / 33^ * s[i] ) % 2^
/
----- i=0
The problem is that the last five bytes of input don't get
multiplied by sufficiently many powers of 33 to rollover 2^32.
That means that changing the last few bytes (but obviously not
the very last) of input will always change the value of the
hash by a multiple of 33. In the case of lagg_hashmbuf() with
ipv4 input, the last four bytes are the TCP or UDP port
numbers. Since the output of lagg_hashmbuf is always taken
modulo the port count, and 3 is a common port count for a lagg,
that's bad. It means that the UDP or TCP source port will
never affect which lagg member is selected on a 3-port lagg.
At 10Gbps, I was not able to measure any difference in CPU
consumption between the old and new hash.

add two targets, 'vm-release' and 'cloudware-release',
that are invoked if WITH_VMIMAGES and WITH_CLOUDWARE
are not empty.
This fixes an issue where 'make release' would not
build the cloud provider targets because CLOUDWARE was
not yet set. [1]
Move the WITH_VMIMAGES and WITH_CLOUDWARE targets to
Makefile.vm.
Note: There is no 'cloudware-install' target yet, since
some of the disk image names may need to be specific to
the provider, so this is probably best handled by the
build scripts.

very questionable, since it makes vimages more dependent on each other. But
the reason for the backout is that it screwed up shutting down the pf purge
threads, and now kernel immedially panics on pf module unload. Although module
unloading isn't an advertised feature of pf, it is very important for
development process.
I'd like to not backout r276746, since in general it is good. But since it
has introduced numerous build breakages, that later were addressed in
r276841, r276756, r276747, I need to back it out as well. Better replay it
in clean fashion from scratch.
While here, fix a bug in which NANO_PMAKE would not be appended at the
appropriate time.
Simply move both checks to after the call to set_defaults_and_export().

The newer boards don't have the response field that indicates
whether the SCSI status byte is present. You have to just look to
see whether it is non-zero.
The code was looking to see whether the sense length was valid
before propagating the SCSI status byte (and sense information) up
the stack. With a status like Reservation Conflict, there is no
sense information, only the SCSI status byte. So it wasn't getting
correctly returned.
isp.c:
In isp_intr(), if we are on a 2400 or 2500 type board and
get a response, look at the actual contents of the
SCSI status value and set the RQSF_GOT_STATUS flag
accordingly so that return any SCSI status value we get. The
RQSF_GOT_SENSE flag will get set later on if there is
actual sense information returned.
