vm_fault: only rely on PG_ZERO when the page was newly allocated
If the fs->m page was found invalid on the object queue, PG_ZERO flag is
stale. Track the source of the page in the new fault state variable
m_needs_zero, and ignore PG_ZERO if the page did not came from the
allocator.

linuxkpi: gracefully handle page lookup failure in lkpi_vmf_insert_pfn_prot_locked
Currently lkpi_vmf_insert_pfn_prot_locked will check the page iter to
find a usage of the page. If no page was found, it continues on to
try using PHYS_TO_VM_PAGE() to get a page. Currently it does not check
if a valid page was found before passing it to vm_page_busy_acquire,
which can cause a kernel page fault as vm_page_busy_acquire expects
a valid page pointer.
This can easily be triggered while starting KDE6 in wayland mode, which
many users have been reporting. With this change plasma6 starts properly
in wayland mode.

bsdinstall: Mount /dev and /packages after using the shell to partition disks
Normally after partitions are created by the installer, the 'mount'
script is used to mount the target disk partitions under /mnt. The
tail end of this script also mounts a couple of additional filesystems
under /mnt so that chrooted programs can work such as devfs and
/packages.
When the "Shell" option is used to permit the user to manually mount
the destination filesystem, the "mount" script is not used as the user
is instructed to mount the target filesystems and construct
/mnt/etc/fstab, etc. However, this means that the user is responsible
for mounting devfs (which is not included in /etc/fstab) and /packages
as well. The help message for the "Shell" option doesn't mention
these requirements, so users may not know to do so. This can lead to
confusing errors as chrooted commands can fail to find needed /dev
entries. For example, running fwget to fetch wireless firmware fails
because /dev/pci doesn't exist.

linux: store Linux Ethernet interface number in struct ifnet
The old approach where we go through the list of interfaces and count them
has bugs. One obvious bug with this dynamic translation is that once an
Ethernet interface in the middle of the list goes away, all interfaces
following it would change their Linux names.
A bigger problem is the ifnet arrival and departure times. For example
linsysfs has event handler for ifnet_arrival_event, and of course it wants
to resolve the name. This accidentially works, due to a bug in
if_attach() where we call if_link_ifnet() before invoking all the event
handlers. Once the bug is fixed linsysfs won't be able to resolve the old
way. The other side is ifnet_departure_event, where there is no bug, the
eventhandlers are called after the if_unlink_ifnet(). This means old
translation won't work for departure event handlers. One example is
netlink. This change gives the Netlink a chance to emit a proper Linux
interface departure message.
However, there is another problem in Netlink, that the ifnet pointer is

ipfilter: Restrict ipfilter within a jail
Add a sysctl/tunable (net.inet.ipf.jail_allowed) to control whether a
jail can manage its own ipfilter rules, pools, and settings. A jail's
control over its own ipfilter rules and settings may not be desireable.
The default is jail access to ipfilter is denied.
The host system can stil manage a jail's rules by attaching the rules,
using the on keyword, limiting the rule to the jail's interface. Or
the sysctl/tunable can be enabled to allow a jail control over its own
ipfilter rules and settings.
Implementation note: Rather than store the jail_allowed variable,
referenced by sysctl(9), in a global area, storing the variable in the
ipfilter softc is consistent with ipfilter's use of its softc.
