src/sys/modules/procfs, branch releng/6.1

MFC rev. 1.29-1.31:

2005-08-20T08:05:01+00:00

Make the procfs module buildable again in the MODULES_WITH_WORLD case.
This means defining a target for default opt_compat.h, but only if we
are not building the modules along with the kernel.

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.

Introduce support for Mandatory Access Control and extensible

2002-08-01T02:03:21+00:00

kernel access control.

Modify procfs so that (when mounted multilabel) it exports process MAC
labels as the vnode labels of procfs vnodes associated with processes.

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

2002-02-04T20:16:50+00:00

Keeping them there seemed like a good idea at the time, but it annoys bde
and confuses people who do not understand how MODULES_OVERRIDE works.

Pseudofsize procfs(5).

- FDESC, FIFO, NULL, PORTAL, PROC, UMAP and UNION file

2001-05-23T09:42:29+00:00

  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

Add four missing source files.

Use .include to get to ../../*/conf/kmod.mk instead of

2000-05-27T01:14:33+00:00

encoding the relative path.

Pull in sys/conf/kmod.mk, rather than /usr/share/mk/bsd.kmod.mk.

2000-05-04T12:08:52+00:00

This means that the kernel can be totally self contained now and is not
dependent on the last buildworld to update /usr/share/mk.  This might
also make it easier to build 5.x kernels on 4.0 boxes etc, assuming
gensetdefs and config(8) are updated.
