Subject: [patch 22/28] x86: Fix broken LDT access in VMI
Date: Mon, 6 Oct 2008 16:17:48 -0700	[thread overview]
Message-ID: <20081006231748.GW20567@suse.de> (raw)
In-Reply-To: <20081006231639.GA20567@suse.de>

[-- Attachment #1: x86-fix-broken-ldt-access-in-vmi.patch --]
[-- Type: text/plain, Size: 1366 bytes --]

2.6.25-stable review patch.  If anyone has any objections, please let us
know.

------------------
From: Zachary Amsden <zach@vmware.com>

commit de59985e3a623d4d5d6207f1777398ca0606ab1c upstream

After investigating a JRE failure, I found this bug was introduced a
long time ago, and had already managed to survive another bugfix which
occurred on the same line.  The result is a total failure of the JRE due
to LDT selectors not working properly.

This one took a long time to rear up because LDT usage is not very
common, but the bug is quite serious.  It got introduced along with
another bug, already fixed, by 75b8bb3e56ca09a467fbbe5229bc68627f7445be
