2007-10-16mmc: need to zero sglist on initJens Axboe
Otherwise we could have junk in the sg fields, fooling the sg chaining into thinking ->page is valid. Acked-by: Pierre Ossman <drzeus@drzeus.cx> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-10-16Panic in blk_rq_map_sg() from CCISS driverLee Schermerhorn
New scatter/gather list chaining [sg_next()] treats 'page' member of struct scatterlist with low bit set [0x01] as a chain pointer to another struct scatterlist [array]. The CCISS driver request function passes an uninitialized, temporary, on-stack scatterlist array to blk_rq_map_sq(). sg_next() interprets random data on the stack as a chain pointer and eventually tries to de-reference an invalid pointer, resulting in: [<ffffffff8031dd70>] blk_rq_map_sg+0x70/0x170 PGD 6090c3067 PUD 0 Oops: 0000 [1] SMP last sysfs file: /block/cciss!c0d0/cciss!c0d0p1/dev CPU 6 Modules linked in: ehci_hcd ohci_hcd uhci_hcd Pid: 1, comm: init Not tainted 2.6.23-rc6-mm1 #3 RIP: 0010:[<ffffffff8031dd70>] [<ffffffff8031dd70>] blk_rq_map_sg+0x70/0x170 RSP: 0018:ffff81060901f768 EFLAGS: 00010206 RAX: 000000040b161000 RBX: ffff81060901f7d8 RCX: 000000040b162c00 RDX: 0000000000000000 RSI: ffff81060b13a260 RDI: ffff81060b139600 RBP: 0000000000001400 R08: 00000000fffffffe R09: 0000000000000400 R10: 0000000000000000 R11: 000000040b163000 R12: ffff810102fe0000 R13: 0000000000000001 R14: 0000000000000001 R15: 00001e0000000000 FS: 00000000026108f0(0063) GS:ffff810409000b80(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 000000008005003b CR2: 000000010000001e CR3: 00000006090c6000 CR4: 00000000000006e0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process init (pid: 1, threadinfo ffff81060901e000, task ffff810409020800) last branch before last exception/interrupt from [<ffffffff8031de0a>] blk_rq_map_sg+0x10a/0x170 to [<ffffffff8031dd70>] blk_rq_map_sg+0x70/0x170 Stack: 000000018068ea00 ffff810102fe0000 0000000000000000 ffff810011400000 0000000000000002 0000000000000000 ffff81040b172000 ffffffff803acd3d 0000000000003ec1 ffff8106090d5000 ffff8106090d5000 ffff810102fe0000 Call Trace: [<ffffffff803acd3d>] do_cciss_request+0x15d/0x4c0 [<ffffffff80298968>] new_slab+0x1c8/0x270 [<ffffffff80298ffd>] __slab_alloc+0x22d/0x470 [<ffffffff8027327b>] mempool_alloc+0x4b/0x130 [<ffffffff8032b21e>] cfq_set_request+0xee/0x380 [<ffffffff8027327b>] mempool_alloc+0x4b/0x130 [<ffffffff8031ff98>] get_request+0x168/0x360 [<ffffffff80331b0d>] rb_insert_color+0x8d/0x110 [<ffffffff8031cfd8>] elv_rb_add+0x58/0x60 [<ffffffff8032a329>] cfq_add_rq_rb+0x69/0xa0 [<ffffffff8031c1ab>] elv_merged_request+0x5b/0x60 [<ffffffff803224fd>] __make_request+0x23d/0x650 [<ffffffff80298ffd>] __slab_alloc+0x22d/0x470 [<ffffffff80270000>] generic_write_checks+0x140/0x190 [<ffffffff8031f012>] generic_make_request+0x1c2/0x3a0 <etc> Kernel panic - not syncing: Attempted to kill init!

2007-10-16remove blk_queue_max_phys_segments in libataFUJITA Tomonori
LIBATA_MAX_PRD is the maximum number of DMA scatter/gather elements permitted by the HBA's DMA engine. It's properly set to q->max_hw_segments via the sg_tablesize parameter. libata shouldn't call blk_queue_max_phys_segments. Now LIBATA_MAX_PRD is equal to SCSI_MAX_PHYS_SEGMENTS by default (both is 128), so everything is fine. But if they are changed, some code (like the scsi mid layer, sg chaining, etc) might not work properly. (Addition from Jens) The basic issue is that the physical segment setting is purely a driver issue. And since SCSI is managing the sglist, libata has no business changing the setting. All libata should care about is the hw segment setting. Signed-off-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

Commit 90833fdab89da02fc0276224167f0a42e5176f41 ("[ARM] 4554/1: replace consistent_sync() with flush_ioremap_region()") introduced a new "flush_ioremap_region()" function to be used by the MTD mainstone-flash and lubbock-flash drivers to fix a regression from around 2.6.18. Those drivers were independently merged into a single driver by Todd Poynor in commit e644f7d6289456657996df4192de76c5d0a9f9c7 ("[MTD] MAPS: Merge Lubbock and Mainstone drivers into common PXA2xx driver") Later, those two commits were merged into the main MTD tree by commit b160292cc216a50fd0cd386b0bda2cd48352c73b ("Merge Linux 2.6.23") by David Woodhouse, but in that merge, the fix to use flush_iomap_region() got lost (as it was to files that now no longer existed).

That ends up not only being unnecessary, but also causes a crash due to the function blindly just trying to pick the first entry off the "gdth_instances" list, and accessing it - which obviously doesn't work if the list is empty!

The strn_pattern_cmp routine does not handle a blank name parameter properly. The only patterns which should match a blank name are "*" and an explicit "". If the function is passed a blank name in current code, it will always match against the patt parameter. The bug manifests itself as the device with the empty model name always matching the first device in the DMA blacklist, forcing it to revert to PIO mode.
