Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> filelock: Fix fcntl/close race recovery compat path<br /> <br /> When I wrote commit 3cad1bc01041 ("filelock: Remove locks reliably when<br /> fcntl/close race is detected"), I missed that there are two copies of the<br /> code I was patching: The normal version, and the version for 64-bit offsets<br /> on 32-bit kernels.<br /> Thanks to Greg KH for stumbling over this while doing the stable<br /> backport...<br /> <br /> Apply exactly the same fix to the compat path for 32-bit kernels.
