3.6.11.6 stable review patch. If anyone has any objections, please let me know.
------------------ From: Dan Carpenter <[email protected]> [ Upstream commit 2a0ebf80aa95cc758d4725f74a7016e992606a39 ] The value of "offd" comes off the instance->rcv_buf[] and we used it as the offset into an array. The problem is that we check the upper bound but not for negative values.
