bouyer 0a2d2af9e0 Restrict umap mounts to root. Letting any user use this has security
implications.

mycroft b174019ccc Pass null pointers to VOP_UPDATE rather than having all the callers fetch the
current time themselves.
1999-03-05 21:09:48 +00:00
wrstuden 862a56e88b Modify vfsops to seperate vfs_fhtovp() into two routines. vfs_fhtovp() now
only handles the file handle to vnode conversion, and a new call,
vfs_checkexp(), performs the export verification.
1999-02-26 23:44:43 +00:00
wrstuden 0078fc50dc Modify VOP_CLOSE vnode op to always take a locked vnode. Change vn_close
to pass down a locked node. Modify union_copyup() to call VOP_CLOSE
locked nodes.

Also fix a bug in union_copyup() where a lock on the lower vnode would
only be released if VOP_OPEN didn't fail.

is fde637530e Machine independent part of fix for PR 6152 (gdb doesn't work on machines
with UVM and seperate I&D-Cache). Mostly by Michael Hitch, but pass struct
proc * instead of the pmap. Reason: said machine will need a method to do
the syncing operation for "curproc", too; this way more code can be shared.

ross e1b25b7bd6 Make spec_write() process errors and return them, otherwise we don't even
notice things like hitting the end of a partition or device.  (To be sure,
writes to block special files are rare, but as long as we support them...)

jonathan fcf7a78c02 Workaropund fix for PR #5239 from <minoura@kw.netlaputa.ne.jp>:
stop  null_node_create() from locking the nullfs mountpoint  multiple
  times. Avoids a guaranteed, repeatably "locking against myself" panic
  during mount of a nullfs filesystem.  nullfs filesystems are still as
  buggy as ever (e.g., see PR# 4907) but this you at least mount them.

thorpej 961f0708b1 - Rename nqnfs_vop_lease_check() to genfs_lease_check(). If NFSSERVER is
not in the kernel, genfs_lease_check() is simply a no-op.  This allows
  LKM'd file systems to be exported (previously did not work properly
  due to a compile-time decision based on -DNFSSERVER).

cgd 651b44e211 Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

marc efbd14c45d mounting a union causes VOP_WHITEOUT to be called on the upper root
vn, with a 0 component.  If the upper fs was a unionfs,
union_whiteout() would deref compnent to get a struct proc, and panic.
struct proc was only being passed to FIXUP, which never used it.  It
turns out this happened a lot.  I ripped most of the unneeded code
out, and left in the few places that really did need the proc handle.

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 fce3e0874f 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.

fixed differently.
1995-06-02 02:39:20 +00:00

1995-05-30 09:37:02 +00:00
mycroft 6760c93567 When a file is removed from the upper layer, make sure to release the
