      IB/mlx5: Keep mlx5 MRs in a radix tree under device · 3bcdb17a
      Sagi Grimberg authored
      This will be useful when processing signature errors on a specific
      key.  The mlx5 driver will lookup the matching mlx5 memory region
      structure and mark it as dirty (contains signature errors).

      IB/mlx5: Remove MTT access mode from umr flags helper function · 2ac45934
      Sagi Grimberg authored
      get_umr_flags helper function might be used for types of access modes
      other than ACCESS_MODE_MTT, such as ACCESS_MODE_KLM.  So remove it from
      helper, and callers will add their own access mode flag.

      IB/mlx5: Break up wqe handling into begin & finish routines · 6e5eadac
      Sagi Grimberg authored
      As a preliminary step for signature feature which will require posting
      multiple (3) WQEs for a single WR, we break post_send routine WQE
      indexing into begin and finish routines.
      
      This patch does not change any functionality.

      IB/mlx5: Initialize mlx5_ib_qp signature-related members · e1e66cc2
      Sagi Grimberg authored
      If user requested signature enable we initialize relevant mlx5_ib_qp
      members.  We mark the qp as sig_enable and we increase the effective
      SQ size, but still limit the user max_send_wr to original size
      computed.  We also allow the create_qp routine to accept sig_enable
      create flag.

      mlx5: Implement create_mr and destroy_mr · 3121e3c4
      Sagi Grimberg authored
      Support create_mr and destroy_mr verbs.  Creating ib_mr may be done
      for either ib_mr that will register regular page lists like
      alloc_fast_reg_mr routine, or indirect ib_mrs that can register other
      (pre-registered) ib_mrs in an indirect manner.
      
      In addition user may request signature enable, that will mean that the
      created ib_mr may be attached with signature attributes (BSF, PSVs).
      
      Currently we only allow direct/indirect registration modes.

      IB/core: Introduce signature verbs API · 1b01d335
      Sagi Grimberg authored
      Introduce a verbs interface for signature-related operations.  A
      signature handover operation configures the layouts of data and
      protection attributes both in memory and wire domains.
      
      Signature operations are:
      
      - INSERT:
        Generate and insert protection information when handing over
        data from input space to output space.
      - validate and STRIP:
        Validate protection information and remove it when handing over
        data from input space to output space.
      - validate and PASS:
        Validate protection information and pass it when handing over
        data from input space to output space.
      
      Once the signature handover opration is done, the HCA will offload
      data integrity generation/validation while performing the actual data
      transfer.
      
      Additions:
      
      1. HCA signature capabilities in device attributes
          Verbs provider supporting signature handover operations fills
          relevant fields in device attributes structure returned by
          ib_query_device.
      
      2. QP creation flag IB_QP_CREATE_SIGNATURE_EN
          Creating a QP that will carry signature handover operations may
          require some special preparations from the verbs provider.  So we
          add QP creation flag IB_QP_CREATE_SIGNATURE_EN to declare that the
          created QP may carry out signature handover operations.  Expose
          signature support to verbs layer (no support for now).
      
      3. New send work request IB_WR_REG_SIG_MR
          Signature handover work request. This WR will define the signature
          handover properties of the memory/wire domains as well as the
          domains layout. The purpose of this work request is to bind all
          the needed information for the signature operation:
      
          - data to be transferred:  wr->sg_list (ib_sge).
            * The raw data, pre-registered to a single MR (normally, before
              signature, this MR would have been used directly for the data
              transfer)
          - data protection guards: sig_handover.prot (ib_sge).
            * The data protection buffer, pre-registered to a single MR, which
              contains the data integrity guards of the raw data blocks.
              Note that it may not always exist, only in cases where the user is
              interested in storing protection guards in memory.
          - signature operation attributes: sig_handover.sig_attrs.
            * Tells the HCA how to validate/generate the protection information.
      
          Once the work request is executed, the memory region that will
          describe the signature transaction will be the sig_mr.  The
          application can now go ahead and send the sig_mr.rkey or use the
          sig_mr.lkey for data transfer.
      
      4. New Verb ib_check_mr_status
          check_mr_status verb checks the status of the memory region post
          transaction.  The first check that may be used is
          IB_MR_CHECK_SIG_STATUS, which will indicate if any signature
          errors are pending for a specific signature-enabled ib_mr.  This
          verb is a lightwight check and is allowed to be taken from
          interrupt context.  An application must call this verb after it is
          known that the actual data transfer has finished.

      IB/core: Introduce protected memory regions · 17cd3a2d
      Sagi Grimberg authored
      This commit introduces verbs for creating/destoying memory
      regions which will allow new types of memory key operations such
      as protected memory registration.
      
      Indirect memory registration is registering several (one
      of more) pre-registered memory regions in a specific layout.
      The Indirect region may potentialy describe several regions
      and some repitition format between them.
      
      Protected Memory registration is registering a memory region
      with various data integrity attributes which will describe protection
      schemes that will be handled by the HCA in an offloaded manner.
      These memory regions will be applicable for a new REG_SIG_MR
      work request introduced later in this patchset.
      
      In the future these routines may replace or implement current memory
      regions creation routines existing today:
      - ib_reg_user_mr
      - ib_alloc_fast_reg_mr
      - ib_get_dma_mr
      - ib_dereg_mr

       "This is the first pull request I've had to do for you, so I'm still

        opportunity to thank them for their many years of effort maintaining
        XFS and supporting the XFS community that they developed from the
        ground up.
      
        So I haven't had time to work things like signed tags into my
        workflows yet, so this is just a repo branch I'm asking you to pull
        from.  And yes, I named the branch -rc4 because I wanted the fixes in
        rc4, not because the branch was for merging into -rc3.  Probably not
        right, either.
      
        Anyway, I should have everything sorted out by the time the next merge
        window comes around.  If there's anything that you don't like in the
        pull req, feel free to flame me unmercifully.
      
        The changes are fixes for recent regressions and important thinkos in

              - a log vector buffer alignment issue on ia32
