* ide: remove IDE_*_REG macrosBartlomiej Zolnierkiewicz2008-04-181-13/+16
| | | | | | | | | | | | | * Add IDE_{ALTSTATUS,IREASON,BCOUNTL,BCOUNTH}_OFFSET defines. * Remove IDE_*_REG macros - this results in more readable and slightly smaller code. There should be no functional changes caused by this patch.

* IDE: Make taskfile interface more robust wrt unexpected end-of-commandLinus Torvalds2008-03-181-9/+27
| | | | | | | | | | | | | | | | | | | | | | | | Now that we handle all the special commands using REQ_TYPE_ATA_TASKFILE rather than using the old REQ_TYPE_ATA_CMD model, we need to also emulate the lack of full taskfile data that comes with the old command model (ie when commands are generated with the HDIO_DRIVE_CMD ioctl rather than using the HDIO_DRIVE_TASK[FILE] ioctls). In particular, this means that we should handle command completion the more relaxed way that the old drive_cmd_intr() code did. It allows commands to finish early even if they don't use up all the data that we thought we had for them. This fixes a regression seen by Anders Eriksson where some SMART commands sent by smartd would cause a boot-time system hang on his machine because the IDE command handling code didn't realize that the command had completed.

* ide: fix ->io_32bit race in ide_taskfile_ioctl()Tejun Heo2008-01-261-5/+12
| | | | | | | | | | | | | | | | | | | In ide_taskfile_ioctl(), there was a race condition involving drive->io_32bit. It was cleared and restored during ioctl requests but there was no synchronization with other requests. So, other requests could execute with the altered ->io_32bit setting or updated drive->io_32bit could be overwritten by ide_taskfile_ioctl(). This patch adds IDE_TFLAG_IO_16BIT flag to indicate to ide_pio_datablock() that 16-bit I/O is needed regardless of drive->io_32bit settting.

* ide: remove broken disk byte-swapping supportBartlomiej Zolnierkiewicz2008-01-261-30/+2
| | | | | | | | | | | | | | | | | | | | | | | Remove broken disk byte-swapping support: - it can cause a data corruption on SMP (or if using PREEMPT on UP) - all data coming from disk are byte-swapped by taskfile_*_data() which results in incorrect identify data being reported by /proc/ide/ and IOCTLs - "hdx=bswap/byteswap" kernel parameter has been broken on m68k host drivers (including Atari/Q40 ones) since 2.5.x days (because of 'hwif' zero-ing) - byte-swapping is limited to PIO transfers (for working with TiVo disks on x86 machines using user-space solutions or dm-byteswap should result in much better performance because DMA can be used) For previous discussions please see: http://www.ussg.iu.edu/hypermail/linux/kernel/0201.0/0768.html http://lkml.org/lkml/2004/2/28/111 [ I have dm-byteswap device mapper target if somebody is interested (patch is for 2.6.4 though but I'll dust it off if needed). ] Acked-by: Sergei Shtylyov <sshtylyov@ru.mvista.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* [PATCH] ide: add sanity checking to ide taskfile ioctlAlan Cox2006-10-161-4/+9
| | | | | | | | | | | Without this the user can feed in bogus values and get very bogus results. Security impact is minimal as this ioctl isn't available to unpriviledged processes anyway. Reported to the l/k list and found with an auditing tool. Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] Split struct request ->flags into two partsJens Axboe2006-09-301-4/+4
| | | | | | | | | | Right now ->flags is a bit of a mess: some are request types, and others are just modifiers. Clean this up by splitting it into ->cmd_type and ->cmd_flags. This allows introduction of generic Linux block message types, useful for sending generic Linux commands to block devices. Signed-off-by: Jens Axboe <axboe@suse.de>
* [PATCH] lockdep: annotate enable_in_hardirq()Ingo Molnar2006-07-031-1/+1
| | | | | | | | | | | | Make use of local_irq_enable_in_hardirq() API to annotate places that enable hardirqs in hardirq context. Has no effect on non-lockdep kernels.
