Add VHD support to mkimg(1). VHD is used by Xen and Microsoft's Hyper-V
among others.
Add an undocumented option for unit testing (-y). When given, the image
will have UUIDs and timestamps synthesized in a way that gives identical
results across runs. As such, UUIDs stop being unique, globally or
otherwise.
Properly advertise that if_arge can handle long frames (if_arge is set to
handle packets up to 1536 bytes)
This fixes the need to frag that could happen when using vlans on top of
if_arge (which is a common case for the use the switch ports as individual
NICs).
Previously to this commit any vlan setup with if_arge as parent would have
the MTU of the parent interface reduced by the size of dot1q header
(4 bytes).
Tested on TP-Link 1043ND (where the WAN port is just a switch port setup to
tag packets in a different VLAN than the LAN ports).

The u-boot tarball needed for some boards, BEAGLEBONE for
example, explicitly hard-code gcc(1) as the compiler.
Partially revert r264703, which did a post-chroot install
of gcc(1). This was initially removed because gcc(1) fails
to build usr.bin/dtc/ causing the xdev target to fail. So
this time, move the gcc(1) installation after xdev is built.
This change is likely applicable to stable/10 arm build
failures, as well.

The EFI framebuffer produces corrupted output on certain systems. For

boot to aid in tracking down these issues.
Micro-manage clang to get the expected inlining for cpu_search().
Mark cpu_search_lowest/cpu_search_highest/cpu_search_both as noinline,
while cpu_search() gets always_inline. With the attributes set,
cpu_search() is inlined in wrappers, and if()s with constant
conditionals are optimized.
On some tests on many-core machine, the hwpmc reported samples for
cpu_search*() are reduced from 25% total to 9%.
- Disable hardware checksumming until it is properly tested.
- Don't discard frames if the dropped or error flag is set.
- Don't remove the last 4-bytes of every packet.
- Add extra range check for data position offset when receiving data.
Rework the BIO_DELETE code slightly. Always queue the BIO_DELETE
requests on the trim_queue, even for the CFA ERASE. This allows us, in
the future, to collapse adjacent requests. Since CFA ERASE is only for
CF cards, and it is so restrictive in what it can do, the collapse
code is not presently here. This also brings the ada driver more in
line with the da driver's treatment of BIO_DELETEs.
Remove ia64 from the list of known architectures and add an entry to
UPDATING. This is the first step towards the removal of ia64 from
head. A buildworld for ia64 will now yield:
% make buildworld
make[1]: "/usr/src/Makefile.inc1" line 151: Unknown target ia64:ia64.
While here, trim the ia64-specific additions from ObsoleteFiles.inc
Improve markup, change references to nonexistent vt_vga(4), remove some
language redundancy, and move the examples so sections are in the
standard order.
Drop KTR records when we're in the debugger so that the debugger isn't
changing or overwriting the trace buffer. When KTR is enabled for things
like traps or pmap functions, the amount of logging can be substantial.
Fix r264346 for ia64. We need to allocate memory for the function
descriptors in order to relocate RTLD itself. To allocate memory,
we need the pagesizes array initialized, but that happens after
RTLD is relocated. This ordering is important for amd64, but it's
opposite of what ia64 needs. Handle this conflict with the define
called RTLD_INIT_PAGESIZES_EARLY. When defined, obtain the page
sizes before relocating rtld, otherwise do it after.

Remove ofwfb(4) in order to fix the LINT build breakage caused by r268069.
Both vt(4) and ofwfb(4) need a lot of love to be usable on sparc64 and even
then the performance of ofwfb(4) would suck compared to hardware accelerated
drivers like creator(4) and machfb(4).
Now that GENERIC can boot on UEFI systems (r268158), switch the build to use
UEFI-compatible images. These will boot as before on BIOS systems, but will
boot using the UEFI loader on UEFI-aware systems.
The UEFI framebuffer driver vt_efifb requires vt(4), so add a mechanism
for the startup routine to set the preferred console. This change is
ugly because console init happens very early in the boot, making a
cleaner interface difficult. This change is intended only to facilitate
the sc(4) / vt(4) transition, and can be reverted once vt(4) is the
default.

Various bugfixes from Stefano Garzarella:
1. oce_multiq_start(): make sure the buffer is consumed even on ENXIO
2. oce_multiq_transmit(): there is an extra call to drbr_enqueue()
causing the mbuf to be enqueued twice when the NIC's queue is full,
and potential panics
3. oce_multiq_transmit(): same problem fixed recently in ixgbe (r267187)
and other drivers: if the mbuf is enqueued, the proper return value is 0

Add support for empty data sets. Data set begin and end pointers
should resolve to "NULL" when not present. This is done by declaring
the data set begin and end symbols as "weak".

Merge the NFSv4.1 server code in projects/nfsv4.1-server over
into head. The code is not believed to have any effect
on the semantics of non-NFSv4.1 server behaviour.
It is a rather large merge, but I am hoping that there will
not be any regressions for the NFS server.
Change NFS readdir() to only ignore cookies preceding the given offset for
UFS rather than for all but ZFS. This code was assuming that offsets were
monotonically increasing for all file systems except ZFS and that the
cookies from a previous call may have been rewound to a block boundary.
According to mckusick@ only UFS is known to do this, so only requests against
UFS file systems should remove cookies smaller than the given offset. This
fixes serving TMPFS over NFS as it too does not have monotonically increasing
offsets. The comment around the code also indicated it was specific to UFS.
Some of the code using 'not_zfs' is specific to ZFS snapshot handling, so
add a 'is_zfs' variable for those cases.
It's possible that 'is_zfs' check for VFS_VGET() support may not be
specific to ZFS. This needs more research and testing.
After this fix TMPFS and other file systems can be served over NFS.
To test I compared the results of syncing a /usr/src tree into a tmpfs and
serving that over NFS. Before the fix 3589 files were missing on the remote
view. After the fix all files were successfully found.
Merge ^/projects/release-debugdist into ^/head:

r262491:
Add DEBUG_DISTRIBUTIONS, and set it to include base and
EXTRA_DISTRIBUTIONS, excluding 'doc', since the documentation
distribution does not have corresponding debug information.
Use DEBUG_DISTRIBUTIONS in the 'distributeworld installworld'
and 'packageworld' targets, to reduce the number of occurances
of excluding distributions that do not have .debug files.
r262493:
In release/Makefile, explicitly set WITHOUT_DEBUG_FILES=1
for dvdrom and cdrom targets. (Later reverted.)
Exclude the *.debug.txz distributions from dvdrom and
cdrom images, but include them for ftp distribution.
r262516:
Rename ${dist}.debug.txz to ${dist}-dbg.txz to prevent the
following output:
eval: ${base....}: Bad substitution
eval: ${doc....}: Bad substitution
eval: ${games....}: Bad substitution
eval: ${lib32....}: Bad substitution
This also follows other naming conventions seen in the
wild.
r267345:
Explicitly set MK_DEBUG_FILES=no, which overrides the
WITH_DEBUG_FILES=1 and WITHOUT_DEBUG_FILES=1 collisions
previously experienced.
This change allows us to create the {base,kernel}_debug.txz
distributions without accidentally installing the *.debug
files on the medium itself.
r267397:
Remove evaluations of MK_DEBUG_FILES where not needed.
If DEBUG_DISTRIBUTIONS is empty, which is true if
MK_DEBUG_FILES evaluates to 'no' above, the loop does
nothing.

Add more formal and strict command parsing and validation.
For every supported command define CDB length and mask of bits that are
allowed to be set. This allows to remove bunch of checks through the code
and still make the validation more strict. To properly do it for commands
supporting multiple service actions, formalize their parsing by adding
subtables for each of such commands.
As visible effect, this change allows to add support for REPORT SUPPORTED
OPERATION CODES command, reporting to client all the data about supported
SCSI commands, except timeouts.
Remove any stale mbuf tags from packets being injected into a netgraph
graph. In particular, this solves some issues with (probably leaked)
IPSec-related tags being looped back through netgraph to the inbound
path which then misinterpreted the stale tags.
Fix order of USB serial layer uninit. Currently module dependency
rules prevent the USB serial module to be unloaded before any client
modules. This patch ensures that the "ucom_mtx" mutex is destroyed

Add initial RSS awareness to the ixgbe(4) driver.
The ixgbe(4) hardware is capable of RSS hashing RX packets and doing RSS
queue selection for up to 8 queues.
However, even if multi-queue is enabled for ixgbe(4), the RX path doesn't use
the RSS flowid from the received descriptor. It just uses the MSIX queue id.
This patch does a handful of things if RSS is enabled:
* Instead of using a random key at boot, fetch the RSS key from the RSS code
and program that in to the RSS redirection table.
That whole chunk of code should be double checked for endian correctness.
* Use the RSS queue mapping to CPU ID to figure out where to thread pin
the RX swi thread and the taskqueue threads for each queue.
* The software queue is now really an "RSS bucket".
* When programming the RSS indirection table, use the RSS code to
figure out which RSS bucket each slot in the indirection table maps
to.
* When transmitting, use the flowid RSS mapping if the mbuf has
an RSS aware hash. The existing method wasn't guaranteed to align
correctly with the destination RSS bucket (and thus CPU ID.)
This code warns if the number of RSS buckets isn't the same as the
automatically configured number of hardware queues. The administrator
will have to tweak one of them for better performance.
There's currently no way to re-balance the RSS indirection table after
startup. I'll worry about that later.
Additionally, it may be worthwhile to always use the full 32 bit flowid if
multi-queue is enabled. It'll make things like lagg(4) behave better with
respect to traffic distribution.
