65990b68a2 msdosfs: clusterfree() is used only in error handling cases
Change its return type to void, because its result is ignored in both

5b13fa7987 ufs: Rework shortlink handling to avoid subobject overflows
Shortlinks occupy the space of both di_db and di_ib when used. However,
everywhere that wants to read or write a shortlink takes a pointer do
di_db and promptly runs off the end of it into di_ib. This is fine on
most architectures, if a little dodgy. However, on CHERI, the compiler
can optionally restrict the bounds on pointers to subobjects to just
that subobject, in order to mitigate intra-object buffer overflows, and
this is enabled in CheriBSD's pure-capability kernels.

Instead, clean this up by inserting a union such that a new di_shortlink
can be added with the right size and element type, avoiding the need to
cast and allowing the use of the DIP macro to access the field. This
also mirrors how the ext2fs code implements extents support, with the
exact same structure other than having a uint32_t i_data[] instead of a
char di_shortlink[].

Apparently some large-file systems out there, such as my powerpc64le

afb6a168f8 Allocate extra inodes in makefs when leaving free space in UFS images.
By default, makefs(8) has very few spare inodes in its output images,
which is fine for static filesystems, but not so great for VM images
where many more files will be added. Make makefs(8) use the same
default settings as newfs(8) when creating images with free space --
there isn't much point to leaving free space on the image if you
can't put files there. If no free space is requested, use current
behavior of a minimal number of available inodes.

ba2cfa80e1 Fix makefs bootstrap after d485c77f20
The makefs msdosfs code includes fs/msdosfs/denode.h which directly uses
struct buf from <sys/buf.h> rather than the makefs struct m_buf.
To work around this problem provide a local denode.h that includes

162ae9c834 Allow bootstrapping makefs on older FreeBSD hosts and Linux/macOS
In order to do so we need to install the msdosfs headers to the bootstrap
sysroot and avoid includes of kernel headers that may not exist on every
host (e.g. sys/lockmgr.h). This change should allow bootstrapping of makefs
on FreeBSD 11+ as well as Linux and macOS.

We also have to avoid using the IO_SYNC macro since that may not be
available. In makefs it is only used to switch between calling
bwrite() and bdwrite() which both call the same function. Therefore we
can simply always call bwrite().

For our CheriBSD builds we always bootstrap makefs by setting
LOCAL_XTOOL_DIRS='lib/libnetbsd usr.sbin/makefs' and use the makefs binary
from the build tree to create a bootable disk image.

aaa3852435 buf: Add B_INVALONERR flag to discard data
Setting the B_INVALONERR flag before a synchronous write causes the buf
cache to forcibly invalidate contents if the write fails (BIO_ERROR).

This is intended to be used to allow layers above the buffer cache to make
more informed decisions about when discarding dirty buffers without
successful write is acceptable.

As a proof of concept, use in msdosfs to handle failures to mark the on-disk
'dirty' bit during rw mount or ro->rw update.

Extending this to other filesystems is left as future work.

8dbc390581 Allow makefs to properly tag UEFI El Torito boot images. Use them in amd64 ISOs.
UEFI booting requires an EFI System Partition (ESP). On most storage devices
this will be in a specific partition type. To allow booting from CD/ISO
filesystems, UEFI will look for an ESP in the form of a FAT filesystem image
embedded in the image. Historically FreeBSD has added one of these to its
amd64 ISO images but marked it as simply another i386 boot image. Luckily for
us most UEFI implementations are rather forgiving and work this out for us.

This change adds the ability to mark a boot image as being a UEFI image. It
also modifies our ISO generation to use this marking for the UEFI image we
embed.
