Fix our ioctl(2) implementation when the argument is "int". New

2006-09-27T19:57:02+00:00

ioctls passing integer arguments should use the _IOWINT() macro.
This fixes a lot of ioctl's not working on sparc64, most notable
being keyboard/syscons ioctls.

Full ABI compatibility is provided, with the bonus of fixing the
handling of old ioctls on sparc64.

Define the target for opt_compat.h only if KERNBUILDDIR

2005-08-18T14:50:08+00:00

is not defined, so that the module will get the
compatibility options from the current kernel configuration
if built with the latter, not with the world.
[Some other modules seem in need of fixing WRT this, too.]

Add more compatibility options found in GENERIC to the default
opt_compat.h.  While not all of them are used in the procfs code,
we can't tell for sure if the system .h files don't need them either,
so let's stay on the safe side.

Slightly change the semantics of vnode labels for MAC: rather than

2002-10-26T14:38:24+00:00

"refreshing" the label on the vnode before use, just get the label
right from inception.  For single-label file systems, set the label
in the generic VFS getnewvnode() code; for multi-label file systems,
leave the labeling up to the file system.  With UFS1/2, this means
reading the extended attribute during vfs_vget() as the inode is
pulled off disk, rather than hitting the extended attributes
frequently during operations later, improving performance.  This
also corrects sematics for shared vnode locks, which were not
previously present in the system.  This chances the cache
coherrency properties WRT out-of-band access to label data, but in
an acceptable form.  With UFS1, there is a small race condition
during automatic extended attribute start -- this is not present
with UFS2, and occurs because EAs aren't available at vnode
inception.  We'll introduce a work around for this shortly.

Move the pseudofs, procfs and linprocfs modules out from the fs directory.

  systems were repo-copied from sys/miscfs to sys/fs.

- Renamed the following file systems and their modules:
  fdesc -> fdescfs, portal -> portalfs, union -> unionfs.

- Renamed corresponding kernel options:
  FDESC -> FDESCFS, PORTAL -> PORTALFS, UNION -> UNIONFS.

- Install header files for the above file systems.

- Removed bogus -I${.CURDIR}/../../sys CFLAGS from userland
  Makefiles.

Use a consistent style and one much closer to the rest of /usr/src
