| |
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
