[PATCH] fix IDE deadlock in error reporting code

2006-06-26T16:58:28+00:00

Michal Piotrowski reported the following validator assert: hdd: set_drive_speed_status: status=0x51 { DriveReady SeekComplete Error } hdd: set_drive_speed_status: error=0xb4 { AbortedCommand LastFailedSense=0x0b } ============================ [ BUG: illegal lock usage! ] ---------------------------- illegal {in-hardirq-W} -> {hardirq-on-W} usage. hdparm/1821 [HC0[0]:SC0[0]:HE1:SE1] takes: (ide_lock){++..}, at: [] ide_dump_opcode+0x13/0x9b [...] stack backtrace: [] show_trace+0x1b/0x20 [] dump_stack+0x1f/0x24 [] print_usage_bug+0x1a5/0x1b1 [] mark_lock+0x2ca/0x4f7 [] __lockdep_acquire+0x47e/0xaa4 [] lockdep_acquire+0x67/0x7f [] _spin_lock+0x24/0x32 [] ide_dump_opcode+0x13/0x9b [] ide_dump_status+0x4a6/0x4cc [] ide_config_drive_speed+0x32a/0x33a [] piix_tune_chipset+0x2ed/0x2f8 [] piix_config_drive_xfer_rate+0x61/0xb5 [] set_using_dma+0x2f/0x60 [] ide_write_setting+0x4a/0xc3 [] generic_ide_ioctl+0x8a/0x47f [] idecd_ioctl+0xfd/0x133 [ide_cd] [] blkdev_driver_ioctl+0x4b/0x5f [] blkdev_ioctl+0x770/0x7bd [] block_ioctl+0x1f/0x21 [] do_ioctl+0x27/0x6e [] vfs_ioctl+0x26a/0x280 [] sys_ioctl+0x4d/0x7e [] sysenter_past_esp+0x63/0xa1 in ide_dump_opcode() takes the ide_lock in an irq-unsafe manner, i.e. this function expects to be called with irqs disabled. But ide_dump_ata[pi]_status() doesnt do that - it enables interrupts specifically. That is a no-no - what guarantees that another IDE port couldnt generate an IDE interrupt while we are dumping this error? The fix is to turn the irq-enabling in these functions into irq-disabling.

[PATCH] ide: fix ide_toggle_bounce() to not try to bounce if we have an IOMMU

2005-11-18T22:13:33+00:00

The following patch fixes a crash caused by attempting to bounce buffer when an IDE CD-ROM is used on a machine with an IO-MMU. [At least, this patch fixes things so I can use my IDE CD-ROM behind an ns87415 on a HP PA-RISC workstation.] Signed-off-by: James Bottomley Signed-off-by: Kyle McMartin Signed-off-by: Bartlomiej Zolnierkiewicz

[PATCH] ide: fix line break in ide messages

From: Denis Vlasenko * printk("\n") is misplaced, resulting in stray empty line in kernel log * cleanups nerby: some back-to-back printks are combined, etc Signed-off-by: Bartlomiej Zolnierkiewicz

Linux-2.6.12-rc2

2005-04-16T22:20:36+00:00

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
