2017-07-20IB/mlx4: Fix CM REQ retries in paravirt modeHåkon Bugge1-0/+4
CM REQs cannot be successfully retried, because a new pv_cm_id is created for each request, without checking if one already exists. By checking if an id exists before creating one, the bug is fixed. This bug can be provoked by running an RDMA CM user-land application, but inserting a five seconds delay before the rdma_accept() call on the passive side. This delay is larger than the default CMA timeout, and triggers a retry from the active side. The retried REQ will use another pv_cm_id (the cm_id on the wire). This confuses the CM protocol and two REJs are sent from the passive side. Here is an excerpt from ibdump running without the patch: 3.285092 LID: 4 -> LID: 4 SDP 290 CM: ConnectRequest(SDP Hello) 7.382711 LID: 4 -> LID: 4 SDP 290 CM: ConnectRequest(SDP Hello) 7.382861 LID: 4 -> LID: 4 InfiniBand 290 CM: ConnectReject 7.387644 LID: 4 -> LID: 4 InfiniBand 290 CM: ConnectReject and here is the same with bug fix applied: 3.251010 LID: 4 -> LID: 4 SDP 290 CM: ConnectRequest(SDP Hello) 7.349387 LID: 4 -> LID: 4 SDP 290 CM: ConnectRequest(SDP Hello) 8.258443 LID: 4 -> LID: 4 SDP 290 CM: ConnectReply(SDP Hello) 8.259890 LID: 4 -> LID: 4 InfiniBand 290 CM: ReadyToUse Suggested-by: Venkat Venkatsubra <venkat.x.venkatsubra@oracle.com> Signed-off-by: Håkon Bugge <haakon.bugge@oracle.com> Reported-by: Wei Lin Guay <wei.lin.guay@oracle.com> Tested-by: Wei Lin Guay <wei.lin.guay@oracle.com> Reviewed-by: Yuval Shaia <yuval.shaia@oracle.com> Acked-by: Jack Morgenstein <jackm@dev.mellanox.co.il> Signed-off-by: Doug Ledford <dledford@redhat.com>
2017-07-20IB/rdmavt: Setting of QP timeout can overflow jiffies computationKaike Wan1-3/+1
Current computation of qp->timeout_jiffies in rvt_modify_qp() will cause overflow due to the fact that the input to the function usecs_to_jiffies is only 32-bit ( unsigned int). Overflow will occur when attr->timeout is equal to or greater than 30. The consequence is unnecessarily excessive retry and thus degradation of the system performance. This patch fixes the problem by limiting the input to 5-bit and calling usecs_to_jiffies() before multiplying the scaling factor.

2017-07-20RDMA/bnxt_re: Fixed the max_rd_atomic support for initiator and destination QPEddie Wai1-2/+13
There's a couple of bugs in the support of max_rd_atomic and max_dest_rd_atomic. In the modify_qp, if the requested max_rd_atomic, which is the ORRQ size, is greater than what the chip can support, then we have to cap the request to chip max as we can't have the HW overflow the ORRQ. Capping the max_rd_atomic support internally is okay to do as the remaining read/atomic WRs will still be sitting in the SQ. However, for the max_dest_rd_atomic, the driver has to error out as this dictates the IRRQ size and we can't control what the remote side sends.

2017-07-20RDMA/bnxt_re: Do not free the ctx_tbl entry if delete GID failsSelvin Xavier1-7/+9
This fix is added only to avoid system crash in some a specific scenario. When bnxt_re driver is loaded and if user tries to change interface mac address, delete GID fails because QP1 is still associated with existing MAC (default GID). If the above command fails GID tables are not modified in the h/w or driver, but the GID context memory is freed. Now, if the user changes the mac back to the original value, another add_gid comes to the driver where the driver reports that the GID is already present in its table and tries to access the context which was already freed. So, in this case, in order to avoid NULL pointer de-reference, this patch removes the context memory free if delete_gid fails and the same context memory is re-used in new add_gid. Memory cleanup will be taken care during driver unload, while deleting the GID table.
