scsi: Fix a harmless double shift bug

2018-12-08T05:27:01Z

Smatch generates a warning: drivers/scsi/scsi_lib.c:1656 scsi_mq_done() warn: test_bit() takes a bit number The problem is that SCMD_STATE_COMPLETE is supposed to be bit number 0 and not a mask like "(1 << 0)". It is used like this: if (test_and_set_bit(SCMD_STATE_COMPLETE, &scmd->state)) The test_and_set_bit() has a shift built in so it's a double left shift and uses bit number 1 instead of number 0. This bug is harmless because it's done consistently and it doesn't clash with any other flags.

scsi: Do not rely on blk-mq for double completions

2018-11-26T17:34:26Z

The scsi timeout error handling had been directly updating the block layer's request state to prevent a error handling and a natural completion from completing the same request twice. Fix this layering violation by having scsi control the fate of its commands with scsi owned flags rather than use blk-mq's.

scsi: Check sense buffer size at build time

2018-08-02T21:23:51Z

To avoid introducing problems like those fixed in commit f7068114d45e ("sr: pass down correctly sized SCSI sense buffer"), this creates a macro wrapper for scsi_execute() that verifies the size of the sense buffer similar to what was done for command string sizes in commit 3756f6401c30 ("exec: avoid gcc-8 warning for get_task_comm"). Another solution could be to add a length argument to scsi_execute(), but this function already takes a lot of arguments and Jens was not fond of that approach. Additionally, this moves the SCSI_SENSE_BUFFERSIZE definition into scsi_device.h, and removes a redundant include for scsi_device.h from scsi_cmnd.h.

block: move ref_tag calculation func to the block layer

2018-07-30T14:27:01Z

Currently this function is implemented in the scsi layer, but it's actual place should be the block layer since T10-PI is a general data integrity feature that is used in the nvme protocol as well.
