2009-10-02[SCSI] sd: Detach DIF from block integrity infrastructureMartin K. Petersen
So far we have only issued DIF commands if CONFIG_BLK_DEV_INTEGRITY is enabled. However, communication between initiator and target should be independent of protection information DMA. There are DIF-only host adapters coming out that will be able to take advantage of this. Move the relevant DIF bits to sd.c. Signed-off-by: Martin K.

2009-10-02[SCSI] Deprecate SCSI_PROT_*_CONVERT operationsMartin K. Petersen
The checksum format is orthogonal to whether the protection information is being passed on beyond the HBA or not. It is perfectly valid to use a non-T10 CRC with WRITE_STRIP and READ_INSERT. Consequently it no longer makes sense to explicitly refer to the conversion in the protection operation. Update sd_dif and lpfc accordingly. Signed-off-by: Martin K.

2009-10-02[SCSI] Retry ADD_TO_MLQUEUE return value for EH commandsHannes Reinecke
A target reset when I/O is ongoing might result an eventual device offline, as scsi_eh_completed_normally() might return ADD_TO_MLQUEUE in addition to the advertised SUCCESS, FAILED, and NEEDS_RETRY. Which is unfortunate as scsi_send_eh_cmnd() will therefore map ADD_TO_MLQUEUE to FAILED instead of the more appropriate NEEDS_RETRY.

2009-10-02[SCSI] sg: Free data buffers after calling blk_rq_unmap_userChristof Schmitt
Running sg_luns on s390x with CONFIG_DEBUG_PAGEALLOC enabled fails with EFAULT from the SG_IO ioctl. The EFAULT is the result from copy_to_user failing in this call chain: sg_ioctl sg_new_read sg_finish_rem_req blk_rq_unmap_user __blk_rq_unmap_user bio_uncopy_user __bio_copy_iov copy_to_user The sg driver calls sg_remove_scat to free the memory pages before calling blk_rq_unmap_user that tries to copy the data back to userspace. Change the order to first call blk_rq_unmap_user before freeing the pages in sg_remove_scat.

2009-10-02[SCSI] bnx2i: Fix context mapping issue for architectures with PAGE_SIZE != 4096Anil Veerabhadrappa
5706/5708/5709 devices allow driver/user to set page size. By default it is set to 4096. Current drivers do not program this register based on architecture type (e.g. x86 = 4K, IA64 = 16K) and by choice lets device use the defaults. So while mapping connection context memory (doorebll registers), driver has to match page size used by the device.

2009-09-30MIPS: SMTC: Remove duplicate structure field initializationJulia Lawall
The definition of the irq_ipi structure has two initializations of the flags field. This combines them. [Ralf: The issue was originally introduced by commit be4894196d79455f420dd7bb78be7dc73bec115c (linux-mips.org) rsp. 033890b084adfa367c544864451d7730552ce8bf (kernel.org). The original intention of the code was to initialize .flags with both flags ored together. The broken C code as actually implemented will be compiled by an equally broken gcc to use only the last initialization, that is IRQF_PERCPU which means this turned into an SMTC bug for 2.6.23 and newer.] The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ identifier I, s, fld; position p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @s@ identifier I, s, r.fld; position r.p0,p; expression E; @@ struct I s =@p0 { ... .fld@p = E, ...}; @script:python@ p0 << r.p0; fld << r.fld; ps << s.p; pr << r.p; @@ if int(ps[0].line)!=int(pr[0].line) or int(ps[0].column)!=int(pr[0].column): cocci.print_main(fld,p0) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

2009-09-30pty: reconnect the BSD TIOCSPTLCK handling to legacy ptysLinus Torvalds
David Howells noticed (due to the compiler warning about an unused 'pty_ops_bsd' variable) that we haven't actually been using the code that implements TIOCSPTLCK for legacy pty handling. It's been that way since 2.6.26, commit 3e8e88ca053150efdbecb45d8f481cf560ec808d to be exact ("pty: prepare for tty->ops changes"). DavidH initially submitted a patch just removing the dead code entirely, and since nobody has apparently ever complained, I'm not entirely sure that wouldn't be the right thing to do. But since the whole and only point of the legacy pty code is to be compatible with legacy distros that don't use the new unix98 pty model, let's just wire it up again. And clean it up a bit while we're at it. Acked-by: David Howells <dhowells@redhat.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
