tv 10d08cc9f2 Only show the "exe" entry to Linux processes, suggested by christos. 
Since there are actually three struct emul's for linux, use the e_name
field to determine eligibility with strcmp().

tv ae4dea1dc4 Some versions of Linux libc look for /proc/.../exe instead of /proc/../file. 
Add an entry for "exe" that is the same as "file", provided only if
COMPAT_LINUX is set.

that expect /proc/self/cmdline to exist.

sommerfeld 197579af47 Change variable used for directory offset from "int" to "off_t". 
Overkill, but avoids a host of truncation problems.

sommerfeld 2e649e46d3 Fix PR8270: 
Problem turned out to be due to improper handling of reads beyond EOF:
they should just return without error with the uio unchanged, and the
caller will recognize this as a zero-byte return (EOF).

The previous fix to protect directory reads against bogus uio_offset
values returned EINVAL, which broke mount -o union, which only
union'ed in the lower directory if the upper directory cleanly
returned EOF.

While we're here, protect kernfs as well.

wrstuden 3bf14d81e9 Add support for fcntl(2) to generate VOP_FCNTL calls. Any fcntl 
call with F_FSCTL set and F_SETFL calls generate calls to a new
fileop fo_fcntl. Add genfs_fcntl() and soo_fcntl() which return 0
for F_SETFL and EOPNOTSUPP otherwise. Have all leaf filesystems
use genfs_fcntl().

wrstuden 9fc36d6807 Bump osrelease to 1.4E. Add layerfs files, remove null_subr.c. 
Update coda to new struct lock in struct vnode.

make fdescfs, kernfs, portalfs, and procfs actually lock their vnodes.
It's not that hard.

Make unionfs set v_vnlock = NULL so any overlayed fs will call its
VOP_LOCK.

thorpej f9777e4a1c Fix the procfs hole described on current-users, similar to a fix for 
FreeBSD by Sean Eric Fagan, but a bit different.  This makes the checks
in the same places as sef's FreeBSD patch, but does not hardcode the
"kmem" group into the kernel, and also does a check identical to the
(3) and (4) checks in the NetBSD ptrace(2):

	(1) it's not owned by you, or is set-id on exec (unless
	    you're root), or

	(2) it's init, which controls the security level of the
	    entire system, and the system was not compiled with
	    permanently insecure mode turned on.

mycroft 53fccab940 Fix vop_link, vop_symlink, and vop_remove semantics in several ways: 
* Change the argument names to vop_link so they actually make sense.
* Implement vop_link and vop_symlink for all file systems, so they do proper
  cleanup.
* Require the file system to decide whether or not linking and unlinking of
  directories is allowed, and disable it for all current file systems.
