IB/iser: DIX update

2014-12-16T02:11:46Z

Following few recent Block integrity updates, we align the iSER data integrity offload settings with: - Deprecate pi_guard module param - Expose support for DIX type 0. - Use scsi_transfer_length for the transfer length - Get pi_interval, ref_tag, ref_remap, bg_type and check_mask setting from scsi_cmnd Signed-off-by: Sagi Grimberg Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier

IB/iser: Remove redundant is_mr indicator

2014-12-16T02:11:45Z

It is enough to check mem_h pointer assignment, mem_h == NULL will indicate that buffer is not registered using mr. Signed-off-by: Sagi Grimberg Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier

IB/iser: Centralize memory region invalidation to a function

2014-12-16T02:11:45Z

Eliminates code duplication. Signed-off-by: Sagi Grimberg Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier

IB/iser: Fix sparse warnings

2014-12-16T02:11:44Z

Use uintptr_t to handle wr_id casting, which was found by Kbuild test robot and smatch. Also remove an internal definition of variable which potentially shadows an external one (and make sparse happy). Signed-off-by: Sagi Grimberg Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier

IB/mlx5, iser, isert: Add Signature API additions

2014-10-09T07:10:53Z

Expose more signature setting parameters. We modify the signature API to allow usage of some new execution parameters relevant to data integrity feature. This patch modifies ib_sig_domain structure by: - Deprecate DIF type in signature API (operation will be determined by the parameters alone, no DIF type awareness) - Add APPTAG check bitmask (for input domain) - Add REFTAG remap (increment) flag for each domain - Add APPTAG/REFTAG escape options for each domain The mlx5 driver is modified to follow the new parameters in HW signature setup. At the moment the callers (iser/isert) hard-code new parameters (by DIF type). In the future, callers will retrieve them from the scsi command structure.

IB/iser: Centralize ib_sig_domain settings

2014-10-09T07:10:53Z

Later there will be more parameters to set, so we want to do it in a centralized place. This patch does not change any functionality. Signed-off-by: Sagi Grimberg Signed-off-by: Roland Dreier

IB/iser: Remove redundant assignment

2014-10-09T07:10:53Z

We clear the struct before - no need to do 0 assignment. Signed-off-by: Sagi Grimberg Signed-off-by: Roland Dreier

IB/iser: Re-introduce ib_conn

2014-10-09T07:06:06Z

Structure that describes the RDMA relates connection objects. Static member of iser_conn. This patch does not change any functionality Signed-off-by: Sagi Grimberg Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier

IB/iser: Rename ib_conn -> iser_conn

2014-10-09T07:06:06Z

Two reasons why we choose to do this: 1. No point today calling struct iser_conn by another name ib_conn 2. In the next patches we will restructure iser control plane representation - struct iser_conn: connection logical representation - struct ib_conn: connection RDMA layout representation This patch does not change any functionality.

IB/iser: Update Mellanox copyright note

2014-04-01T18:09:46Z

Update Mellanox copyrights for 2014 on the iser initiator driver. Signed-off-by: Or Gerlitz Signed-off-by: Roland Dreier
