This helps ensure that overflows will trigger a panic instead of
silently corrupting adjacent buffers, as happened in SA-26:13.exec.
Extend kmap_alloc_wait() to support allocation of guard pages on both

the "vm.exec_map_guard_pages" tunable to provide control over the guard

Commit c4f08d46c7 moved the symlinks for the LLVM binutils from LLVM
itself to the toolchain (usr.bin/clang/toolchain), but did not remove
the links for /usr/bin/gcov and /usr/bin/objdump from the llvm version,
meaning we installed them twice, once in the clang package and once in

Remove the links from the llvm version and move the MLINKs to toolchain,

Commit 71ac1ec5c9 disabled callbacks for the NFS
client for NFSv4.0. This patch does the same for
the NFSv4.0 server.
The only use for callbacks for NFSv4.0 is delegations
and delegations rarely work well for NFSv4.0 anyhow.
Therefore, this patch disables callbacks for the
NFSv4.0 server. This is the same behavior as
occurs when vfs.nfsd.issue_delegations is 0.
This change allowed the functions called
nfsrv_getclientipaddr() and nfsrv_getipnumber() to be
removed from the kernel.

When the krpc was vnet'd, the VNET macros were hidden
behind macros that had the KRPC_ prefix on them.
This was done because, at the time, it was thought
that something other than vnet might be used for this.
That has not happened and probably will not happen,
so this patch replaces these obscuring macros with
the regular vnet ones.
There should be no semantics change caused by

There is no point to do it. The VNON type is good enough for fdescfs
operations, and changing the type on stat(2) is arbitrary and does not
serve much purpose, because we recalculate the returned file type on
each stat(2) anyway.
But setting the type to VLNK has undesired consequence of namei()
trying VOP_READLINK() there, which might fail since it defer the
calculation of path to vn_fullpath().

Enable the FMan hardware parser to take advantage of some offloading.
This enables receive and transmit checksum offloading for both IPv4 and
IPv6.
Additional offloading capabilities the DPAA supports include:
* vlan parsing
* Transmit rate limiting
* IEEE-1588 timestamps
* Soft parsing for custom protocol checking
* Congestion handling
The NCSW reference base requires tuning for each target, and currently
is configured for FMANv2. This doesn't readily work on FMANv3 devices,
such as the T-series powerpc, or the LS1043 ARM. Since Freescale/NXP
abandoned the NCSW driver a decade ago, it makes sense to abandon it
ourselves as well. This new driver uses a combination of the NCSW
driver and the Linux driver (BSD/GPL dual licensed) as a reference, but
contains no actual code from them.
The DPAA (Data Path Acceleration Architecture) subsystem consists of the
following components:
* BMan -- Buffer Manager. Manages buffer pools of different sizes (one
size per pool, up to 64 pools)
* QMan -- Queue Manager. Manages the interfaces between DPAA-based
components and the CPU(s).
* FMan -- Frame Manager. Responsible for all ethernet-related
processing. Consists itself of the following components:
* Ports -- interfaces to the QMan. An ethernet interface consists of
2 ports.
Ports use "Next-invoked action" (NIA) descriptors to form a pipeline
for processing on receive and transmit.
* Parser -- performs protocol header parsing and validation. Both
hardware and software parsers are available.
* KeyGen -- Key generator, used to start the classification process
(for the Policer), generating FQIDs and other keys based on the
frame input.
* Policer -- performs traffic shaping and classification
* MAC -- SoC specific ethernet MAC (dTSEC, TGEC, mEMAC). Currently
supports dTSEC and mEMAC, along with their MDIO blocks.
Additional components not yet handled:
SEC -- Security engine (crypto)
RE -- RAID engine
RapidIO
DCE -- Decompression/Compression engine, supports ZLIB, DEFLATE, and
GZIP, as well as base64 encoding and decoding.
BMan and QMan are accessed via cache-coherent portals, using ring
buffers as I/O. The intent is for portals to be per-CPU (core/thread)
to reduce locking contention and improve performance. This driver pins
interrupt handlers to the CPU "owning" a given portal, and uses critical
sections to prevent switching while accessing the portal.
Three architecture dependent manuals are installed to MANSUBDIRs,

For unicast tests, it is sufficient to use wait_for_carp() to verify
the setup is sane. Additional sanity checks are not necessarily
required but can serve purpose for redundancy.
For some unclear reason routed(8) is advertising route to carp BACKUP.
That makes the test flaky. Also routed(8) is marked deprecated and may
be removed from base in the future. Let's just add static route entry
manually for additional sanity checks.
Other noticeable changes:
1. Add atf_check to configuration steps to prevent potential failure
on setup. That helps diagnosing on failure.
2. Shorten the names of jails to improve readability.
3. Prefer `[ifconfig|route|sysctl] -j` over `jexec [ifconfig|route|sysctl]`
to make the lines shorter.

Without this patch, all upcalls to the gssd daemon are
done in vnet0 (outside of any vnet jail). This does
not work well, because a user principal's credential
cache can be within the jail (/tmp/krb5cc_NNN in the
jail's namespace).
This patch modifies the client so that RPCs done
from within vnet jails does an upcall to a gssd
daemon running within the vnet jail. It required
that the cache of uid->credential shorthands in
the rpcsec_gss be vnet'd.
The situation is still less than ideal and sec=krb5[ip]
mounts that are visible within vnet jails is still
not something I would recommend, but it can work ok
with this patch.
Vnet'ng the NFS client so that mounts can be done
within vnet jails is probably more useful, but that
will require additional work.
