      RDMA/siw: Fix SGL mapping issues · fab4f97e
      Bernard Metzler authored
      All user level and most in-kernel applications submit WQEs
      where the SG list entries are all of a single type.
      iSER in particular, however, will send us WQEs with mixed SG
      types: sge[0] = kernel buffer, sge[1] = PBL region.
      Check and set is_kva on each SG entry individually instead of
      assuming the first SGE type carries through to the last.
      This fixes iSER over siw.
      Fixes: b9be6f18 ("rdma/siw: transmit path")

      RDMA/bnxt_re: Fix stack-out-of-bounds in bnxt_qplib_rcfw_send_message · d37b1e53
      Selvin Xavier authored
      Driver copies FW commands to the HW queue as  units of 16 bytes. Some
      of the command structures are not exact multiple of 16. So while copying
      the data from those structures, the stack out of bounds messages are
      reported by KASAN. The following error is reported.

      Fix this by passing the exact size of each FW command to
      bnxt_qplib_rcfw_send_message as req->cmd_size. Before sending
      the command to HW, modify the req->cmd_size to number of 16 byte units.
