| * block: move the padding adjustment to blk_rq_map_sgFUJITA Tomonori2008-04-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | blk_rq_map_user adjusts bi_size of the last bio. It breaks the rule that req->data_len (the true data length) is equal to sum(bio). It broke the scsi command completion code. commit e97a294ef6938512b655b1abf17656cf2b26f709 was introduced to fix the above issue. However, the partial completion code doesn't work with it. The commit is also a layer violation (scsi mid-layer should not know about the block layer's padding). This patch moves the padding adjustment to blk_rq_map_sg (suggested by James). The padding works like the drain buffer. This patch breaks the rule that req->data_len is equal to sum(sg), however, the drain buffer already broke it. So this patch just restores the rule that req->data_len is equal to sub(bio) without breaking anything new. Now when a low level driver needs padding, blk_rq_map_user and blk_rq_map_user_iov guarantee there's enough room for padding. blk_rq_map_sg can safely extend the last entry of a scatter list. blk_rq_map_sg must extend the last entry of a scatter list only for a request that got through bio_copy_user_iov. This patches introduces new REQ_COPY_USER flag.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Every current transport class calls transport_container_release but ignores the return value. This is catastrophic if it returns an error because the containers are part of a global list and the next action of almost every transport class is to free the memory used by the container. Fix this by making transport_container_release a void, but making it BUG if attribute_container_release returns an error ... this catches the root cause of a system panic much earlier. If we don't do this, we get an eventual BUG when the attribute container list notices the corruption caused by the freed memory it's still referencing. Also made attribute_container_release __must_check as a reminder. Cc: Greg KH <greg@kroah.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
| * [SCSI] fix barrier failure issueJames Bottomley2008-04-071-6/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, if the barrier command fails, the error return isn't seen by the block layer and it proceeds on regardless. The problem is that SCSI always returns no error for REQ_TYPE_BLOCK_PC ... it expects the submitter to pick the errors out of req->errors, which the block barrier functions don't do. Since it appears that the way SG_IO and scsi_execute_request() work they discard the block error return and always use req->errors, the best fix for this is to have the SCSI layer return an error to block if one actually occurred (this also allows us to filter out spurious errors, like deferred sense). This patch is a bug fix that will need backporting to stable, but it's also quite a big change and in need of testing, so we'll incubate in the main kernel tree and backport at the -rc2 or so stage if no problems turn up.

| | | | | | | | | | | | | | | | | | | | header.context is a 64 bit field, but it's deliberately split into context and context_hi32. Thus cpu_to_le64 assignments are wrong on this.
