The userdata associated with a transfer was lost in the case that a non-blocking mode was used. 2. The 64-bit ioctl compatibility shim for a bulk transfer used the wrong ioctl command. This patch set fixes both of those bugs, and adds a security-related note to the TODO file. Changes in v2: - Expand the commit message on patch 1 to clarify the impact of the bug, and add Tested-by. - Add commit 3 with an additional TODO item. - Change the name of the patch set to be numerically accurate.
