scsi: target: core: Make hw_max_sectors store the sectors amount in blocks

2022-11-24T02:16:19Z

By default, hw_max_sectors stores its value in 512 blocks in iblock, despite the fact that the block size can be 4096 bytes. Change hw_max_sectors to store the number of sectors in hw_block_size blocks.

scsi: target: Fix WRITE_SAME No Data Buffer crash

2022-07-07T20:38:14Z

In newer version of the SBC specs, we have a NDOB bit that indicates there is no data buffer that gets written out. If this bit is set using commands like "sg_write_same --ndob" we will crash in target_core_iblock/file's execute_write_same handlers when we go to access the se_cmd->t_data_sg because its NULL. This patch adds a check for the NDOB bit in the common WRITE SAME code because we don't support it. And, it adds a check for zero SG elements in each handler in case the initiator tries to send a normal WRITE SAME with no data buffer.

Secure erase is a very different operation from discard in that it is a data integrity operation vs hint. Fully split the limits and helper infrastructure to make the separation more clear.
