980bae6980 Redo r359164 now that it's baked : Eliminate misuse of $MACHINE for userland things.
Use TARGET_ARCH and/or MACHINE_ARCH exclusively. Change all __TT uses to __T
with appropriate translations. MACHINE/TARGET is to be used only for kernel
things, and this fixes the last few stragglers.

99258935eb Lock the socket in soo_stat().
Otherwise nothing synchronizes with a concurrent conversion of the
socket to a listening socket.

Only the PF_LOCAL protocols implement pru_sense, and it is safe to hold
the socket lock there, so do so for now.

Previously they included sys/dev/cx/machdep.h, but the cx driver was

a decade or more so there's no real benefit in sharing this file; just

pci_iov_if.h was added to pci.h, but none of the kms-drm branches have

e02582d1ae Fix synchronization in the IPV6_2292PKTOPTIONS set handler.
The inpcb needs to be locked when we update output packet options.
Otherwise it is possible for the IPV6_2292PKTOPTIONS handler to free
packet option structures while another thread is reading or updating
them.

Note that the option handler is still kind of broken.  For instance it
frees all options before performing privilege checks for individual
options.  However, this can be fixed separately.

2d896b816b Enter a write sequence when updating rights.
The Capsicum system calls modify file descriptor table entries.  To
ensure that readers observe a consistent snapshot of descriptor writes,
the system calls need to signal to unlocked readers that an update is
pending.

Note that ioctl rights are always checked with the descriptor table lock
held, so it is not strictly necessary to signal unlocked readers.
However, we probably want to enable lockless ioctl checks eventually, so
use seqc_write_begin() in kern_cap_ioctls_limit() too.

d2568b024d pfctl: improve rule load times with thousands of interfaces
r343287 / D18759 introduced ifa_add_groups_to_map() which is now run by
ifa_load/ifa_lookup/host_if. When loading an anchor or ruleset via pfctl that
does NOT contain ifnames as hosts, host() still ends up iterating all
interfaces twice, grabbing SIOCGIFGROUP ioctl twice for each. This adds an
unnecessary amount of time on systems with thousands or tens of thousands of
interfaces.

Prioritize the IPv4/6 check over the interface name lookup, which skips loading
the iftab and iterating all interfaces when the configuration does not contain
interface names.

d3c6ba3214 MFOpenZFS: make zil max block size tunable
We've observed that on some highly fragmented pools, most metaslab
allocations are small (~2-8KB), but there are some large, 128K
allocations.  The large allocations are for ZIL blocks.  If there is a
lot of fragmentation, the large allocations can be hard to satisfy.

The most common impact of this is that we need to check (and thus load)
lots of metaslabs from the ZIL allocation code path, causing sync writes
to wait for metaslabs to load, which can take a second or more.  In the
worst case, we may not be able to satisfy the allocation, in which case
the ZIL will resort to txg_wait_synced() to ensure the change is on
disk.

To provide a workaround for this, this change adds a tunable that can
reduce the size of ZIL blocks.
