Mount on a LE machine a filesystem formatted for BE is not supported
currently. This adds a check for the superblock magic number using
swapped bytes to guess and warn the user that it may be a valid

The SCMI specification describes a set of standard interfaces for power,
performance and system management.
SCMI is extensible and provides interfaces to access functions which are
often implemented in firmwares in the System Control Processor (SCP).
This implements Shared Memory-based transfer, which is one of the ways on
how messages are exchanged between agents and the platform.
This includes a driver for ARM Message Handling Unit (MHU) Doorbell, which
is a mechanism that the caller can use to alert the callee of the presence
of a message.
The support implements clock management interface. For instance this allows
us to control HDMI pixel clock on ARM Morello Board.
Tested on ARM Morello Board.

For file mounts, the directory vnode is not available from namei and this
prevents the use of vn_fullpath_hardlink. In this case, we can use the
vnode which was covered by the file mount with vn_fullpath.
This also disallows file mounts over files with link counts greater than
one to ensure a deterministic path to the mount point.

The main use-case for this is to support mounting config files and
secrets into OCI containers. My current workaround copies the files into
the container which is messy and risks secrets leaking into container
images if the cleanup fails.
This adds a VFCF flag to indicate whether the filesystem supports file
mounts and allows fspath to be either a directory or a file if the flag
is set.
Test Plan:
$ sudo mkdir -p /mnt
$ sudo touch /mnt/foo
$ sudo mount -t nullfs /COPYRIGHT /mnt/foo

Pull Request: https://github.com/freebsd/freebsd-src/pull/621
Differential Revision: https://reviews.freebsd.org/D37203
This patch modifies the kernel RPC so that it will allow
mountd/nfsd to run inside of a vnet jail. Running mountd/nfsd
inside a vnet jail will be enabled via a new kernel build
option called VNET_NFSD, which will be implemented in future
commits.
Although I suspect cr_prison can be set from the credentials
of the current thread unconditionally, I #ifdef'd the code
VNET_NFSD and only did this for the jailed case mainly to
document that it is only needed for use in a jail.
The TLS support code has not yet been modified to work in
a jail. That is planned as future development after the
basic VNET_NFSD support is in the kernel.
This patch should not result in any semantics change until
VNET_NFSD is implemented and used in a kernel configuration.

Native networking via eqos driver
USB3 and USB2
PCIe support is working but a bit picky about what hardware it supports (but so is Linux)
SD & (e)MMC
With the EDK2 loader video also works
Supported hardwares are Quartz64, NanoPI R5S and Firefly Station P2, more to come as DTS files gets done.

It appears that, prior to r158857 vfs_domount() checked
suser() when MNT_EXPORTED was specified.
r158857 appears to have broken this, since MNT_EXPORTED
was no longer set when mountd.c was converted to use nmount(2).
r164033 replaced the suser() check with
priv_check(td, PRIV_VFS_MOUNT_EXPORTED), which does the
same thing (ie. checks for effective uid == 0 assuming suses_enabled
is set).
This patch restores this check by setting MNT_EXPORTED when the
"export" mount option is specified to nmount().
I think this is reasonable since only mountd(8) should be setting
exports and I doubt any non-root mounted file system would
be setting its own exports.

pr_abort calls tcp_usr_abort which calls tcp_drop with ECONNABORTED.
After pr_abort returns, the so_error is then set to a more specific
error. However, a reader can observe and return the ECONNABORTED
error before so_error is set to the desired error value. This is
resulting in spurious test failures of recently added tests for
invalid conditions such as invalid headers.
To fix, refactor the code to abort a connection to call tcp_drop
directly with the desired error value. ktls_reset_send_tag already
calls tcp_drop directly when it aborts a connection due to an error.
