[patch] RDMA/cxgb3: information leak in send_abort()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The cpl_abort_req struct has several reserved members which need to be
cleared to avoid disclosing kernel information.  I have added a memset()
so now it matches the cxgb4 version of this function.
