5140034cc0 Add a new mode to the scripted partition editor for variant disk names.
If the disk parameter "DEFAULT" is set in place of an actual device name,
or no disk is specified for the PARTITIONS parameter, the installer will
follow the logic used in the automatic-partitioning mode, in which it
will either provide a selection dialog for one of several disks if
several are present or automatically select it if there is only one. This
simplifies the creation of fully-automatic installation media for
hardware or VMs with varying disk names.

fdcfe8a298 LinuxKPI: netdevice notifier callback argument
Introduce struct netdev_notifier_info as a container to pass
net_device to the callback functions.
Adjust netdev_notifier_info_to_dev() to return the net_device field.

Add explicit casts from ifp to ni->dev even though currently
struct net_device is defined to struct ifnet.  This is needed in
preparation for untangling this and improving the net_device compat
code.

b6fd00791f [iwn] Flip over to use VAP flags rather than ic flags for things
net80211 changed a while back to support per-VAP config for things
rather than it being global.  This is to support firmware NICs that
support per-VAP flags and configuration where the firmware will figure
out how to combine them.

However, it introduced a fun timing issue - those changes used to happen
to the shared ic state before newstate() was called, but now they're
also tasks and they can happen /after/.

This isn't a problem for ath(4), but it exposed some interesting
timing and config bugs here.  Notably, I saw short slot NOT being
configured in 5GHz mode during some associations, so 5GHz stuff
would hang or behave poorly.  Other times the follow-up auth has
the right config, so it didn't hang.

So for now, just flip this over to using the per-VAP flags which
are correct when newstate() is called.  net80211 should also have
those flags synch'ed to the global ic state before newstate() runs
and that can come in a subsequent commit.

Whilst here also fix plcp to be consistently logged as a hex value.

Tested:

* iwn(4) Intel 6205, STA mode, both 2GHz and 5GHz

653a437c04 accept_filter: Fix filter parameter handling
For filters which implement accf_create, the setsockopt(2) handler
caches the filter name in the socket, but it also incorrectly frees the
buffer containing the copy, leaving a dangling pointer.  Note that no
accept filters provided in the base system are susceptible to this, as
they don't implement accf_create.

15f3355567 cxgbe(4): Allow a T6 adapter to switch between TOE and NIC TLS mode.
The hw.cxgbe.kern_tls tunable was used for this in the past and if it
was set then all T6 adapters would be configured for NIC TLS operation
and could not be reconfigured for TOE without a reload.  With this
change ifconfig can be used to manipulate toe and txtls caps like any
other caps.  hw.cxgbe.kern_tls continues to work as usual but its
effects are not permanent any more.

* Enable nic_ktls_ofld in the default configuration file and use the
  firmware instead of direct register manipulation to apply/rollback
  NIC TLS configuration.  This allows the driver to switch the hardware
  between TOE and NIC TLS mode in a safe manner.  Note that the
  configuration is adapter-wide and not per-port.

* Remove the kern_tls config file as it works with 100G T6 cards only
  and leads to firmware crashes with 25G cards.  The configurations
  included with the driver (with the exception of the FPGA configs) are
  supposed to work with all adapters.

3d0399c718 [PowerPC64] Clear low-order bits of ARPN
PowerISA 2.07B says that the low-order p-12 bits of the real page number
contained in ARPN and LP fields of a PTE must be 0s and are ignored
by the hardware (Book III-S, 5.7.7.1), where 2^p is the actual page size
in bytes, but we were clearing only the LP field.

This worked on bare metal and QEMU with KVM, that ignore these bits,
but caused a kernel panic on QEMU with TCG, that expects them to be
cleared.

This fixes running FreeBSD with HPT superpages enabled on QEMU
with TCG.

7daca4e204 truss: improved support for decoding compat32 arguments
Currently running `truss -a -e` does not decode any
argument values for freebsd32_* syscalls (open/readlink/etc.)

This change checks whether a syscall starts with freebsd{32,64}_ and if
so strips that prefix when looking up the syscall information. To ensure
that the truss logs include the real syscall name we create a copy of
the syscall information struct with the updated.

The other problem is that when reading string array values, truss
naively iterates over an array of char* and fetches the pointer value.
This will result in arguments not being loaded if the pointer is not
aligned to sizeof(void*), which can happens in the compat32 case. If it
happens to be aligned, we would end up printing every other value.
To fix this problem, this changes adds a pointer_size member to the
procabi struct and uses that to correctly read indirect arguments
as 64/32 bit addresses in the the compat32 case (and also compat64 on
CheriBSD).

The motivating use-case for this change is using truss for 64-bit
programs on a CHERI system, but most of the diff also applies to 32-bit
compat on a 64-bit system, so I'm upstreaming this instead of keeping it
as a local CheriBSD patch.

7848b25edd Fix fsck_ffs -R finds unfixed duplicate block errors when rerunning.
This fixes a long-standing but very obscure bug in fsck_ffs when
it is run with the -R (rerun after unexpected errors).  It only
occurs if fsck_ffs finds duplicate blocks and they are all contained
in inodes that reside in the first block of inodes (typically among
the first 128 inodes).

Rather than use the usual ginode() interface to walk through the
inodes in pass1, there is a special optimized `getnextinode()'
routine for walking through all the inodes. It has its own private
buffer for reading the inode blocks. If pass 1 finds duplicate
blocks it runs pass 1b to find all the inodes that contain these
duplicate blocks. Pass 1b also uses the `getnextinode()' to search
for the inodes with duplicate blocks. Pass 1b stops when all the
duplicate blocks have been found. If all the duplicate blocks are
found in the first block of inodes, then the getnextinode cache
holds this block of bad inodes. The subsequent cleanup of the inodes
in passes 2-5 is done using ginode() which uses the regular fsck_ffs
cache.

When fsck_ffs restarts, pass1() calls setinodebuf() to point at the
first block of inodes. When it calls getnextinode() to get inode
2, getnextino() sees that its private cache already has the first
set of inodes loaded and starts using them. They are of course the
trashed inodes left over from the previous run of pass1b().

The fix is to always invalidate the getnextinode cache when calling
setinodebuf().

5a402a3ae3 LinuxKPI: add pci_ids.h
brcm80211 include pci_ids.h directly while historically we were tracking
IDs in pci.h.  Move the current set of IDs from pci.h to pci_ids.h and
while here add IDs for Realtek and Broadcom as well as a network class
as needed by their wireless drivers.

We still include pci_ids.h from pci.h so this should not change anything.

f90218886f rtld: introduce PRELOAD_FDS
The new PRELOAD_FDS variable accepts a list of file descriptors
that should be loaded into the process.

This may be used to optimize a loading process - in the case when
we already have a file descriptor to the library; we don't have
to look into multiple PATH to find it.

It may also be used in capability mode to load a single additional
library without the need to open a directory that contains it.

The last use of this functionality t may be a race-free method
of loading libraries.

a29bbfe6c6 ofed/linuxkpi: use proper accessor function
In the notifier event callback function rather than casting directly
to the expected type use the proper accessor function as the mlx drivers
already do.
This is preparational work to allow us to improve the struct net_device
is struct ifnet compat code shortcut in the future.

de8a7cc703 linuxkpi: add ieee80211_node.h to headers to include before LIST_HEAD
ieee80211_node.h uses LIST_HEAD() which LinuxKPI redefines and this
can lead to problems (see comment there).  Make sure the net80211
header file is handled correctly by adding it to the list of files
to include before re-defining the macro.
Also add header files needed as dependencies.

af7d9f8e31 net80211: prefix get_random_bytes() with net80211_
Both linux/random.h and net80211 have a function named
get_random_bytes().  With overlapping files included these collide.
Arguably the function could be renamed in linuxkpi but the generic
name should also not be used in net80211 so rename it there.

efad9c8ba3 align nfsdumpstate column output
There are scenarios where an NFS client will mount an NFSv4 export
without specifying a callback address.

When running nfsdumpstate under this circumstance, the column output is
shifted incorrectly which places the "ClientID" value underneath the
"Clientaddr" column.

This diff is a small cosmetic change that prints a blank in the
"Clientaddr" column and ensures the data for the columns are aligned
appropriately.
