scsi: bfa: Fix function pointer type mismatch for hcb_qe->cbfn

2024-03-26T22:22:41Z

[ Upstream commit b69600231f751304db914c63b937f7098ed2895c ] Some callback functions used here take a boolean argument, others take a status argument. This breaks KCFI type checking, so clang now warns about the function pointer cast: drivers/scsi/bfa/bfad_bsg.c:2138:29: error: cast from 'void (*)(void *, enum bfa_status)' to 'bfa_cb_cbfn_t' (aka 'void (*)(void *, enum bfa_boolean)') converts to incompatible function type [-Werror,-Wcast-function-type-strict] Assuming the code is actually correct here and the callers always match the argument types of the callee, rework this to replace the explicit cast with a union of the two pointer types. This does not change the behavior of the code, so if something is actually broken here, a larger rework may be necessary. Fixes: 37ea0558b87a ("[SCSI] bfa: Added support to collect and reset fcport stats") Fixes: 3ec4f2c8bff2 ("[SCSI] bfa: Added support to configure QOS and collect stats.")

[SCSI] bfa: Revised Fabric Assigned Address(FAA) feature implementation.

2012-03-28T08:55:22Z

Made changes to the Fabric Assigned Address(FAA) feature implementation. Introduced the IOCFC state machine, which now handles the FAA logic, IOC and BFA sub-modules enablement. Removed un-wanted FAA enable/disable routines; FAA is enabled by default. Signed-off-by: Krishna Gudipati Signed-off-by: James Bottomley

[SCSI] bfa: Introduced initiator based lun masking feature.

2011-07-27T10:55:03Z

- Added support to enable initiator based lun masking. - Initiator based Lun masking works similar to zoning where initiator port is allowed to see only those LUNs which are configured to be seen. Signed-off-by: Krishna Gudipati Signed-off-by: James Bottomley

[SCSI] bfa: Add support to store driver configuration in flash.

2011-07-27T10:54:03Z

- Added dconf (Driver Config) BFA sub-module. - The dconf sub-module provides interfaces and manages flash writes to the flash DRV parition. - dconf sub-module also ensures that the whole 64K DRV partition is updated on a flash write. Signed-off-by: Krishna Gudipati Signed-off-by: James Bottomley

[SCSI] bfa: Added support to collect and reset fcport stats

2011-07-27T10:48:52Z

- Added support to collect and reset fcport stats. - Modified design to allow multiple requests for fcport stats. - fcport will remember the stats request in its stats_pending queue and service each of the queued requests after receiving a firmware response for the prior request.

[SCSI] bfa: Update RME interrupt handling.

2011-07-27T10:44:48Z

- Made changes to always acknowledge RME interrupt and update consumer index (CI) when RME interrupt is generated. - Made changes to have ASIC specific hw_rspq_ack() handler. Signed-off-by: Krishna Gudipati Signed-off-by: James Bottomley
