      RDMA/nes: CM connection setup/teardown rework · 6492cdf3
      由 Faisal Latif 提交于 
      Major rework of CM connection setup/teardown.  We had a number of issues
with MPI applications not starting/terminating properly over time.
With these changes we were able to run longer on larger clusters.

* Remove memory allocation from nes_connect() and nes_cm_connect().
* Fix mini_cm_dec_refcnt_listen() when destroying listener.
* Remove unnecessary code from schedule_nes_timer() and nes_cm_timer_tick().
* Functionalize mini_cm_recv_pkt() and process_packet().
* Clean up cm_node->ref_count usage.
* Reuse skbs if available.

      RDMA/nes: Fix off-by-one in nes_reg_user_mr() error path · 24797a34
      由 Roland Dreier 提交于 
      nes_reg_user_mr() should fail if page_count becomes >= 1024 * 512
rather than just testing for strict >, because page_count is
essentially used as an index into an array with 1024 * 512 entries, so
allowing the loop to continue with page_count == 1024 * 512 means that
memory after the end of the array is corrupted.  This leads to a crash
triggerable by a userspace application that requests registration of a
too-big region.

Also get rid of the call to pci_free_consistent() here to avoid
corrupting state with a double free, since the same memory will be
freed in the code jumped to at reg_user_mr_err.

      RDMA/nes: Fix up nes_lro_max_aggr module parameter · dd37818d
      由 Roland Dreier 提交于 
      Fix some bugs with the max_aggr module parameter added with LRO support:

 - The module parameter value ignored and not actually used to set
   lro_mgr.max_aggr.
 - MODULE_PARM_DESC had a typo "_mro_" instead of "_lro_" so it didn't
   end up describing the actual module parameter.
 - The nes_lro_max_aggr variable was declared as unsigned, but the
   module_param line said "int" instead of "uint" for the type.
 - The default value for the parameter was stuck in the permissions
   field of module_param, which led to nonsensical permissions for the
   file under /sys/module/iw_nes/param.
 - The parameter was used in only one file but defined in another, which
   led to the variable being global for no good reason.  Move everything
   related to the parameter to the file nes_hw.c where it is actually
   used.

      RDMA/nes: Remove volatile qualifier from struct nes_hw_cq.cq_vbase · 31d1e340
      由 Roland Dreier 提交于 
      Remove the volatile qualifier from the cq_vbase member of struct
nes_hw_cq, and add an rmb() in the one place where it looks like
access order might make a difference.  As usual, removing a volatile
qualifier in a declaration is actually a bug fix, since a volatile
qualifier is not sufficient to make sure that aggressively
out-of-order CPUs don't reorder things and cause incorrect results.

For example, a CPU might speculatively execute reads of other cqe
fields before the NIC hardware has written those fields and before it
has set the NES_CQE_VALID bit (even though those reads come after the
test of the NES_CQE_VALID bit in program order), but then when the CPU
actually executes the conditional test of the NES_CQE_VALID, the bit
has been set, and the CPU will proceed with the results of the earlier
speculative execution and end up using bogus data.

This also gets rid of the warning:

    drivers/infiniband/hw/nes/nes_verbs.c: In function 'nes_destroy_cq':
    drivers/infiniband/hw/nes/nes_verbs.c:1978: warning: passing argument 3 of 'pci_free_consistent' discards qualifiers from pointer target type

      RDMA/nes: Fix adapter reset after PXE boot · bc5698f3
      由 Chien Tung 提交于 
      After PXE boot, the iw_nes driver does a full reset to ensure the card
is in a clean state.  However, it doesn't wait for firmware to
complete its work before issuing a port reset to enable the ports,
which leads to problems bringing up the ports.

The solution is to wait for firmware to complete its work before
proceeding with port reset.

This bug was flagged by Roland Dreier <rolandd@cisco.com>.
