Fix an early return in ctld UCL parser
If the UCL ctld parser encountered a port that used the CTL

following the port attribute to be skipped. Fix this by replacing
the return with a continue so that the rest of the config is

The function which checks for a valid LBA range mistakenly named an

Fix is to rename the variable to avoid future confusion.
While in the neighborhood, also check that the starting LBA is less than

This adds the ability for a guest OS to send Set / Get Feature,

implements the Composite Temperature.
While in the neighborhood, move the clear of the CSTS register in the

(cherry picked from commit 62d47feceb)
The NVM Format command is unique among the Admin commands in that it
needs to finish asynchronously. For this reason, the emulation code
invented a synthetic completion status (NVME_NO_STATUS) to indicate that
the command was still in progress and the command processing loop should
not generate a completion message. The implementation used the value
0xffff for the synthetic value as this set both the Status Code and
Status Code Type fields to reserved values.
Format initialized the completion status to this value and expected
error cases to override it with a status code/type appropriate to the
situation. The macros used to set the NVMe status are careful not to
modify bit 0 (i.e. the phase bit), which with the synthetic completion
status, causes the phase bit to get out of sync. When running tests in a
guest with illegal NVM Format commands, Admin commands would eventually
hang because it appeared there were no completions due to the incorrect
phase bit value.
Fix is to only set NVME_NO_STATUS if the blockif delete command
succeeds. While in the neighborhood, add a missing break statement when
NVM Format is not supported.

NVMe conformance tests for the Format command failed if the
backing-storage for the bhyve device was a file instead of a Zvol. The
tests (and the specification) expect a Format to destroy all previously
written data. The bhyve NVMe emulation implements this by trimming /
deallocating all data from the backing-storage.
The blockif_candelete() function indicated the file did not support
deallocation (i.e. fpathconf(..., _PC_DEALLOC_PRESENT) returned FALSE)
even though the kernel supported file hole punching. This occurs on
builds with Capsicum enabled because blockif did not allow the
fpathconf(2) right.
Fix is to add CAP_FPATHCONF to the cap_rights_init(3) call.

In GNU ld and ld.lld, -dc is used with -r to allocate space to COMMON
symbols. It is presumably to work around legacy code which cannot
handle COMMON symbols in relocatable output. ld.lld may remove -dc or
make it a no-op for the 15.0.0 release.
As of 7420b323a0 crunch/crunchide does not require -dc, as the symbol
hiding technique no longer relied on making symbols local.
In addition -fno-common is now the default in Clang and GCC, so -dc
serves no purpose as the compiler does not generate COMMON symbols
anyway.

This addresses one nit and one bug in the BE creation feature of
freebsd-update:
The nit addressed is that it currently only names the BEs after the
userland version, but the kernel version may be higher. After this
change, we request both and pass them through sort(1) to choose the
highest. This is especially helpful if a freebsd-update patch touched
one but not the other.
The bug fixed is that roots updated that are not located at '/', e.g.,
by using -b or -j, will no longer create boot environments
automatically. There's a very low chance these will actually change the
BE in any meaningful way, anyways. It could make sense in the future
to allow an argument-override to create the BE anyways if someone comes
up with a non-standard setup, e.g., where a jail is an important part of
their boot environment on an appliance or some such setup.
Half of this patch is submitted by delphij@, the other half kevans@.
