Before this change on every open da(4) driver read all mode pages to
use only one bit. It was done so to not depend on the list of pages
supported by the disk. But I've found that at least for SATL of LSI/
Broadcom HBAs with WD HDDs Power Condition mode page reading may take
significant amount of time, much more than any other mode page, that
visibly increased disk retaste time by GEOM.
Address that by using data returned by the first MODE SENSE request
to limit the following ones to only one (the first for now) mode page.
With the change simultaneous retaste of 39 SATA disks takes about 2.5s
instead of more than 4s before, and I no longer see "dareprobe" status
on GEOM event thread.

In iflib_device_register(), the CTX_LOCK is acquired first and then
IFNET_WLOCK is acquired by ether_ifattach(). However, in netmap_hw_reg()
we do the opposite: IFNET_RLOCK is acquired first, and then CTX_LOCK
is acquired by iflib_netmap_register(). Fix this LOR issue by wrapping
the CTX_LOCK/UNLOCK calls in iflib_device_register with an additional
IFNET_WLOCK. This is safe since the IFNET_WLOCK is recursive.

Buckets in an SMR-enabled zone can legitimately be tagged with
SMR_SEQ_INVALID. This effectively means that the zone destructor (if
any) was invoked on all items in the bucket, and the contained memory is
safe to reuse. If the first bucket in the full bucket list was tagged
this way, UMA would unnecessarily poll per-CPU state before attempting
to fetch a full bucket from the list.

The roundrobin pool stores its state in the rule, which could
potentially lead to invalid addresses being returned.
For example, thread A just executed PF_AINC(&rpool->counter) and
immediately afterwards thread B executes PF_ACPY(naddr, &rpool->counter)
(i.e. after the pf_match_addr() check of rpool->counter).
Lock the rpool with its own mutex to prevent these races. The
performance impact of this is expected to be low, as each rule has its
own lock, and the lock is also only relevant when state is being created
(so only for the initial packets of a connection, not for all traffic).

default). Fix this by using a for loop that does the assignment before

To check if it needed to regenerate a packet's header before

for all supported guest types (HVM and PVH). Note that for HVM the

to differentiate between PVH and HVM.
While there fix the shutdown handler to properly differentiate between

Mark Milliard has detected a case of undefined behavior with the LLVM
UBSAN. The mandoc program called qsort with a==NULL and n==0, which is
allowed by the POSIX standard. The qsort() in FreeBSD did not attempt
to perform any accesses using the passed pointer for n==0, but it did
add an offset to the pointer value, which is undefined behavior in
case of a NULL pointer. This operation has no adverse effects on any
achitecture supported by FreeBSD, but could be caught in more strict
environments.
After some discussion in the freebsd-current mail list, it was
concluded that the case of a==NULL and n!=0 should still be caught by
UBSAN (or cause a program abort due to an illegal access) in order to
not hide errors in programs incorrectly invoking qsort().
Only the the case of a==NULL and n==0 should be fixed to not perform
the undefined operation on a NULL pointer.
This commit makes qsort() exit before reaching the point of
potentially undefined behvior for the case n==0, but does not test
the value of a, since the result will not depend on whether this
pointer is NULL or an actual pointer to an array if n==0.
The issue found by Mark Milliard in the whatis command has been
reported to the upstream (OpenBSD) and has already been patched
there.
