The fr_info struct contains a summary of a packet. One of its fields
is a pointer to the ifnet struct the packet arrived on. It is pointed
to by a void* because ipfilter supports multiple O/Ses. Unfortunately
this makes it difficult it examine with DTrace. Defining fin_ifp as a
pointer to an ifnet struct makes the struct it points to using a DTrace
script possible.

With various firmware files used by graphics and wireless drivers
we are exceeding the current 32 character module name (file path
in kldxref) length.
In order to overcome this issue bump it to the maximum path length
for the next version.
To be able to MFC provide backward compat support for another version
of the struct as the offsets for the second half change due to the
array size increase.
MAXMODNAME being defined to MAXPATHLEN needs param.h to be
included first. With only 7 modules (or LinuxKPI module.h) not
doing that adjust them rather than including param.h in module.h [1].

gzlib.c uses lseek but does not include unistd.h, where it is defined to

When SOCK_DGRAM is used, a portion of the datagram is discarded during

To workaround this, use MSG_PEEK for the initial recv() when using a

Over the past few months we published multiple snapshots for this
Linux derived driver and it has become fairly stable in terms of
minimal local changes needed for new updates.
The current version is based on iwlwifi-next update at
cbaa6aeedee5f92dafa5982eceea2a1f98ce4f7d with the addition of
a hand full of files replaced for FreeBSD.
Given the lack of full license texts on non-local files this is
imported under the draft policy for handling SPDX files (D29226). [1]
Do not yet hook this to the build until the remaining compat code
is all in. Along with the firmware import this will make publishing
the last bits and final testing a lot easier.

When rolling back a dataset, ZFS has to purge file data resident in the
system page cache. To do this, it loops over all vnodes for the
mountpoint and calls vn_pages_remove() to purge pages associated with
the vnode's VM object. Each page is thus exclusively busied while the
dataset's teardown write lock is held.
When handling a page fault on a mapped ZFS file, FreeBSD's page fault
handler busies newly allocated pages and then uses VOP_GETPAGES to fill
them. The ZFS getpages VOP acquires the teardown read lock with vnode
pages already busied. This represents a lock order reversal which can
lead to deadlock.
To break the deadlock, observe that zfs_rezget() need only purge those
pages marked valid, and that pages busied by the page fault handler are,
by definition, invalid. Furthermore, ZFS pages always transition from
invalid to valid with the teardown lock held, and ZFS never creates
partially valid pages. Thus, zfs_rezget() can use the new
vn_pages_remove_valid() to skip over pages busied by the fault handler.

This reverts commit 59eab1093a.
The change suppressed EFAULT originating from uiomove(). The deadlock
avoidance mechanism implemented by vn_io_fault1() in the VFS handles
such errors by wiring the user pages and retrying, but this change
caused read() to return early instead. This can result in short I/O,
causing misbehaviour in some applications, and possibly other
consequences.
Until this is resolved somehow, revert the commit.

When a nvlist(9) is converted into a binary buffer by nvlist_pack(9),
the host endianness is encoded in the nvlist_header of the binary
buffer. The nvlist_unpack(9) function converts a given binary buffer
to an nvlist. In the conversion process the endianness encoded in the
nvlist_header is evaluated and -- should the encoded endianness differ
from the endianess of the decoding host -- endianness conversion is
applied to nvlist_header and nvpair_header elements as well as
to some nvpair values.
In 2015 @oshogbo extended libnv with array support (in 347a39b).
The unpacking code misses the possible need to convert the endianness
of the nvph_nitems element of nvpair_headers.
The patch (re)enables libnv to unpack nvlists regardless of the
endianness of the packing host.

This problem of undefined behavior was also reported to acpica by @cem
in 2018: https://github.com/acpica/acpica/issues/407, but it seems there
was never any fix committed for it upstream.
Instead fix these locally, for ACPI_TO_INTEGER by simply casting the
incoming pointer to ACPI_SIZE (which corresponds roughly to uintptr_t
and size_t), and for ACPI_OFFSET by reusing our __offsetof definition
from sys/cdefs.h.

Implement kernel support for RFC 5549/8950.
* Relax control plane restrictions and allow specifying IPv6 gateways
for IPv4 routes. This behavior is controlled by the
net.route.rib_route_ipv6_nexthop sysctl (on by default).
* Always pass final destination in ro->ro_dst in ip_forward().
* Use ro->ro_dst to exract packet family inside if_output() routines.
Consistently use RO_GET_FAMILY() macro to handle ro=NULL case.
* Pass extracted family to nd6_resolve() to get the LLE with proper encap.
It leverages recent lltable changes committed in c541bd368f.
Presence of the functionality can be checked using ipv4_rfc5549_support feature(3).

When a prefix gets deleted from the RIB, dpdk_lpm algo needs to know
the nexthop of the "parent" prefix to update its internal state.
The glue code, which utilises RIB as a backing route store, uses
fib[46]_lookup_rt() for the prefix destination after its deletion
to fetch the desired nexthop.
This approach does not work when deleting less-specific prefixes
with most-specific ones are still present. For example, if
10.0.0.0/24, 10.0.0.0/23 and 10.0.0.0/22 exist in RIB, deleting
10.0.0.0/23 would result in 10.0.0.0/24 being returned as a search
result instead of 10.0.0.0/22. This, in turn, results in the failed
datastructure update: part of the deleted /23 prefix will still
contain the reference to an old nexthop. This leads to the
use-after-free behaviour, ending with the eventual crashes.
Fix the logic flaw by properly fetching the prefix "parent" via
newly-created rt_get_inet[6]_parent() helpers.
