(Btw, 40944 is possible if the disk is a\n CDRW that was formatted with \"cdrwtool -m 10236\".)\n\n The problem is that pktcdvd opens the cd device in non-blocking mode\n when pktsetup is run, and doesn\u0027t close it again until pktsetup -d is\n run. The effect is that if you meanwhile open the cd device,\n blkdev.c:do_open() doesn\u0027t call bd_set_size() because\n bdev-\u003ebd_openers is non-zero.\"\n\nIn particular, to repeat the bug (regardless of whether commit\n6f5391c283d7fdcf24bf40786ea79061919d1e1d is applied or not):\n\n \" 1. Start with an empty drive.\n 2. pktsetup 0 /dev/scd0\n 3. Insert a CD containing an isofs filesystem.\n 4. mount /dev/pktcdvd/0 /mnt/tmp\n 5. umount /mnt/tmp\n 6. Press the eject button.\n 7. Insert a DVD containing a non-writable filesystem.\n 8. mount /dev/scd0 /mnt/tmp\n 9. find /mnt/tmp -type f -print0 | xargs -0 sha1sum \u003e/dev/null\n 10. If the DVD contains data beyond the physical size of a CD, you\n get I/O errors in the terminal, and dmesg reports lots of\n \"attempt to access beyond end of device\" errors.\"\n\nwhich in turn is because the nested open after the media change won\u0027t\ncause the size to be set properly (because the original open still holds\nthe block device, and we only do the bd_set_size() when we don\u0027t have\nother people holding the device open).\n\nThe proper fix for that is probably to just do something like\n\n\tbdev-\u003ebd_inode-\u003ei_size \u003d (loff_t)get_capacity(disk)\u003c\u003c9;\n\nin fs/block_dev.c:do_open() even for the cases where we\u0027re not the\noriginal opener (but *not* call bd_set_size(), since that will also\nchange the block size of the device).\n\nCc: Peter Osterlund \u003cpetero2@telia.com\u003e\nCc: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nCc: Matthew Wilcox \u003cmatthew@wil.cx\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ac40532ef0b8649e6f7f83859ea0de1c4ed08a19", "tree": "ca86d577fe7fe68ae28b7f7d020f86bc9fff5535", "parents": [ "158a962422e4a54dc256b6a9b9562f3d30d34d9c" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Wed Jan 02 17:25:34 2008 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Wed Jan 02 13:11:06 2008 -0800" }, "message": "scsi: revert \"[SCSI] Get rid of scsi_cmnd-\u003edone\"\n\nThis reverts commit 6f5391c283d7fdcf24bf40786ea79061919d1e1d (\"[SCSI]\nGet rid of scsi_cmnd-\u003edone\") that was supposed to be a cleanup commit,\nbut apparently it causes regressions:\n\n Bug 9370 - v2.6.24-rc2-409-g9418d5d: attempt to access beyond end of device\n http://bugzilla.kernel.org/show_bug.cgi?id\u003d9370\n\nthis patch should be reintroduced in a more split-up form to make\ntesting of it easier.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nAcked-by: Matthew Wilcox \u003cmatthew@wil.cx\u003e\nCc: James Bottomley \u003cJames.Bottomley@HansenPartnership.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "6f5391c283d7fdcf24bf40786ea79061919d1e1d", "tree": "32ee9abddf9879445792019e1c03bcd28ce6bd4f", "parents": [ "687d2bc4877081a44c41b5b312e012cc69edda53" ], "author": { "name": "Matthew Wilcox", "email": "matthew@wil.cx", "time": "Tue Sep 25 12:42:04 2007 -0400" }, "committer": { "name": "James Bottomley", "email": "jejb@mulgrave.localdomain", "time": "Fri Oct 12 14:52:46 2007 -0400" }, "message": "[SCSI] Get rid of scsi_cmnd-\u003edone\n\nThe ULD -\u003edone callback moves into the scsi_driver.
