KVM: ia64: Fix irq disabling leak in error handling code

KVM: Avoid instruction emulation when event delivery is pending
When an event (such as an interrupt) is injected, and the stack is
shadowed (and therefore write protected), the guest will exit. The
current code will see that the stack is shadowed and emulate a few
instructions, each time postponing the injection. Eventually the
injection may succeed, but at that time the guest may be unwilling
to accept the interrupt (for example, the TPR may have changed).
This occurs every once in a while during a Windows 2008 boot.
Fix by unshadowing the fault address if the fault was due to an event
injection.

[PATCH] dup3 fix
Al Viro notice one cornercase that the new dup3() code. The dup2()
function, as a special case, handles dup-ing to the same file
descriptor. In this case the current dup3() code does nothing at
all. I.e., it ingnores the flags parameter. This shouldn't happen,
the close-on-exec flag should be set if requested.
In case the O_CLOEXEC bit in the flags parameter is not set the
dup3() function should behave in this respect identical to dup2().
This means dup3(fd, fd, 0) should not actively reset the c-o-e
flag.

This is equivalent to the original. The reason it is needed, is that

[patch 05/14] hpfs: dont call permission()
hpfs_unlink() calls permission() prior to truncating the file. HPFS
doesn't define a .permission method, so replace with explicit call to

This is equivalent, except that devcgroup_inode_permission() and

The truncation is just an implementation detail of the unlink, so
these security checks are unnecessary.

[PATCH] sysctl: keep track of tree relationships
In a sense, that's the heart of the series. It's based on the following
property of the trees we are actually asked to add: they can be split into
stem that is already covered by registered trees and crown that is entirely
new. IOW, if a/b and a/c/d are introduced by our tree, then a/c is also
introduced by it.
That allows to associate tree and table entry with each node in the union;
while directory nodes might be covered by many trees, only one will cover
the node by its crown. And that will allow much saner logics for /proc/sys
in the next patches. This patch introduces the data structures needed to
keep track of that.
When adding a sysctl table, we find a "parent" one. Which is to say,
find the deepest node on its stem that already is present in one of the
tables from our table set or its ancestor sets. That table will be our
parent and that node in it - attachment point. Add our table to list
anchored in parent, have it refer the parent and contents of attachment
point. Also remember where its crown lives.

[PATCH] allow delayed freeing of ctl_table_header
Refcount the sucker; instead of freeing it by the end of unregistration
just drop the refcount and free only when it hits zero. Make sure that
we _always_ make ->unregistering non-NULL in start_unregistering().
That allows anybody to get a reference to such puppy, preventing its
freeing and reuse. It does *not* block unregistration. Anybody who
holds such a reference can
* try to grab a "use" reference (ctl_head_grab()); that will
succeeds if and only if it hadn't entered unregistration yet. If it
succeeds, we can use it in all normal ways until we release the "use"
reference (with ctl_head_finish()). Note that this relies on having
->unregistering become non-NULL in all cases when one starts to unregister
the sucker.
* keep pointers to ctl_table entries; they *can* be freed if
the entire thing is unregistered. However, if ctl_head_grab() succeeds,
we know that unregistration had not happened (and will not happen until
ctl_head_finish()) and such pointers can be used safely.
IOW, now we can have inodes under /proc/sys keep references to ctl_table
entries, protecting them with references to ctl_table_header and
grabbing the latter for the duration of operations that require access
to ctl_table. That won't cause deadlocks, since unregistration will not
be stopped by mere keeping a reference to ctl_table_header.

[patch] vfs: fix lookup on deleted directory
Lookup can install a child dentry for a deleted directory. This keeps
the directory dentry alive, and the inode pinned in the cache and on
disk, even after all external references have gone away.
This isn't a big problem normally, since memory pressure or umount
will clear out the directory dentry and its children, releasing the
inode. But for UBIFS this causes problems because its orphan area can
overflow.
Fix this by returning ENOENT for all lookups on a S_DEAD directory
before creating a child dentry.
Thanks to Zoltan Sogor for noticing this while testing UBIFS, and
Artem for the excellent analysis of the problem and testing.
