The UFS1 integrity checks added in FreeBSD 14 were too aggressive
for UFS1 filesystems created in FreeBSD 4 and 9 systems. This patch
removes those tests which can be done safely since they are not
relevant to the current implementation of UFS1.

The LIT_MEM option uses slightly more memory (for base gzip(1),
about 16kiB; according to the author, about 6% for default deflate
settings) for a small speedup.
The performance gain is more noticeable for input data with higher
entropy and less significant for data that is highly compressible,
such as source code and logs.

To allow gcc -m32 to work, link libc and libthr with --rpath-/usr/lib32.
When called with -m32, gcc is currently unable to communicate to
the bfd linker that it should look in /usr/lib32 to resolve needed (as
opposed to explicitly linked) libraries so we need to provide a hint.

This ensures that rtld updates the correct (only) copy of

Currently there is no support for generating armv7 vm images in the
release artifacts. In fact in terms of release artifacts and
architecture there is no good reason to have a vm release artifact for
armv7 as those are mostly used in SOCs or embedded boards. However
considering that developers actually do need an easy way to test armv7
with a vm running this is really important. As part of pre-commit ci for
developers this can be really helpful for the end developers.

If a file is specified then fileargs_init(3) may return [EINTR]. With
the SIGINFO handler not being SA_RESTART this causes an early exit
if a SIGINFO comes in. Rather than checking for [EINTR] or changing the
handler just move it later which resolves the problem.

unionfs_mkshadowdir() may be invoked on a non-leaf pathname component
during lookup, in which case the NUL terminator of the pathname buffer
will be well beyond the end of the current component. cn_namelen in
this case will still (correctly) indicate the length of only the
current component, but ZFS in particular does not currently respect
cn_namelen, leading to the creation on inacessible files with slashes
in their names. Work around this behavior by temporarily NUL-
terminating the current pathname component for the call to VOP_MKDIR().

a proper upstream fix for the issue at hand.

If the underlying upper FS supports shared locking for write ops,
as is the case with ZFS, VOP_FSYNC() may only be called with the vnode
lock held shared. In this case, temporarily upgrade the lock for
those unionfs maintenance operations which require exclusive locking.
While here, make unionfs inherit the upper FS' support for shared
write locking. Since the upper FS is the target of VOP_GETWRITEMOUNT()
this is what will dictate the locking behavior of any unionfs caller
that uses vn_start_write() + vn_lktype_write(), so unionfs must be
prepared for the caller to only hold a shared vnode lock in these
cases.

Store the upper/lower FS mount objects in unionfs per-mount data and
use these instead of the v_mount field of the upper/lower root
vnodes. As described in the referenced PR, it is unsafe to access this
field on the unionfs unmount path as ZFS rollback may have obliterated
the v_mount field of the upper or lower root vnode. Use these stored
objects to slightly simplify other code that needs access to the
upper/lower mount objects as well.

Select between text-only and graphical frame buffer consoles for the
BIOS boot loader. Pull one or the other in with #ifdef in conf.c. Add
gfx_bios.c for the few routines that are needed for the BIOS support of
gfx. These are stubbed out for text-only mode. Move bi_load_vbe_data
here since it's only used for the graphical frame buffer.
Note: This setup also allows us to build multiple BIOS loaders if we
have to, some with text-only and some graphical. We don't do this today.
We may be forced to turn this on in the future if ZFS keeps growing.
The size savings is 41k, which helps a lot with some of our users that
want to enable more options in the BIOS boot loader than are normally
safe to do, and they don't need graphics.

out of space when too many options are selected, so this allows people
to select the smaller one to spend the space elsewhere. This is only the

The is a bug in MSDOSFS that can be triggered when the target of a
rename operation exists. It is caused by the lack of inodes in the
FAT file system, which are substituted by the location of the DOS 8.3
directory entry in the file system. This causes the "inode" of a file
to change when its directory entry is moved to a different location.
The rename operation wants to re-use the existing directory entry
position of an existing target file name (POS1). But the code does
instead locate the first position in the directory that provides
sufficient free directory slots (POS2) to hold the target file name
and fills it with the directory data.
The rename operation continues and at the end writes directory data to
the initially retrieved location (POS1) of the old target directory.
This leads to 2 directory entries for the target file, but with
inconsistent data in the directory and in the cached file system
state.
The location that should have been re-used (POS1) is marked as deleted
in the directory, and new directory data has been written to a
different location (POS2). But the VFS cache has the newly written
data stored under the inode number that corresponds to the initially
planned position (POS1).
If then a new file is written, it can allocate the deleted directory
entries (POS1) and when it queries the cache, it retrieves data that
is valid for the target of the prior rename operation, leading to a
corrupt directory entry (at POS1) being written (DOS file name of the
earlier rename target combined with the Windows long file name of the
newly written file).
