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.

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.

ODP depends on the several device capabilities, among them is the ability to send UMR WQEs with that modify atomic and entity size of the MR. Therefore, only if all conditions to send such a UMR WQE are met then driver can report that ODP is supported. Use this check of conditions in all places where driver needs to know about ODP support. Also, implicit ODP support depends on ability of driver to send UMR WQEs for an indirect mkey. Therefore, verify that all conditions to do so are met when reporting support.

If QP is not visible to the pid, then we try to decrease its reference count and return from the function before the QP pointer is initialized. This lead to NULL pointer dereference.

In a congested fabric with adaptive routing enabled, traces show that packets could be delivered out of order. A stale TID RDMA data packet could lead to TidErr if the TID entries have been released by duplicate data packets generated from retries, and subsequently erroneously force the qp into error state in the current implementation. Since the payload has already been dropped by hardware, the packet can be simply dropped and it is no longer necessary to put the qp into error state.

When processing a TID RDMA READ RESP packet that causes KDETH EFLAGS errors, the packet's IB PSN is checked against qp->s_last_psn and qp->s_psn without the protection of qp->s_lock, which is not safe.

In a congested fabric with adaptive routing enabled, traces show that the sender could receive stale TID RDMA NAK packets that contain newer KDETH PSNs and older Verbs PSNs. If not dropped, these packets could cause the incorrect rewinding of the software flows and the incorrect completion of TID RDMA WRITE requests, and eventually leading to memory corruption and kernel crash. The current code drops stale TID RDMA ACK/NAK packets solely based on KDETH PSNs, which may lead to erroneous processing. This patch fixes the issue by also checking the Verbs PSN. Addition checks are added before rewinding the TID RDMA WRITE DATA packets. Fixes: 9e93e967 ("IB/hfi1: Add a function to receive TID RDMA ACK packet") Cc: <stable@vger.kernel.org> Reviewed-by:
