3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Oliver Neukum <[email protected]> commit 2f338c8a1904e2e7aa5a8bd12fb0cf2422d17da4 upstream. cleanup() is not called if the last close() comes after disconnect(). That leads to a memory leak. Rectified by checking for an earlier disconnect() in release() Signed-off-by: Oliver Neukum <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]> --- drivers/usb/class/cdc-wdm.c | 2 ++ 1 file changed, 2 insertions(+) --- a/drivers/usb/class/cdc-wdm.c +++ b/drivers/usb/class/cdc-wdm.c @@ -625,6 +625,8 @@ static int wdm_release(struct inode *ino kill_urbs(desc); if (!test_bit(WDM_DISCONNECTING, &desc->flags)) desc->manage_power(desc->intf, 0); + else + cleanup(desc); } mutex_unlock(&wdm_mutex); return 0; -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
