2008-07-25isofs: fix minor filesystem corruptionAdam Greenblatt
Some iso9660 images contain files with rockridge data that is either incorrect or incompletely parsed. Prior to commit f2966632a134e865db3c819346a1dc7d96e05309 ("[PATCH] rock: handle directory overflows") (included with kernel 2.6.13) the kernel ignored the rockridge data for these files, while still allowing the files to be accessed under their non-rockridge names. That commit inadvertently changed things so that files with invalid rockridge data could not be accessed at all. (I ran across the problem when comparing some old CDs with hard disk copies I had made long ago under kernel 2.4: a few of the files on the hard disk copies were no longer visible on the CDs.) This change reverts to the pre-2.6.13 behavior.

2008-02-07iget: stop ISOFS from using read_inode()David Howells
Stop the ISOFS filesystem from using read_inode(). Make isofs_read_inode() return an error code, and make isofs_iget() pass it on.

Same as with already do with the file operations: keep them in .rodata and prevents people from doing runtime patching. Signed-off-by: Christoph Hellwig <hch@lst.de> Cc: Steven French <sfrench@us.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-06-21[PATCH] rock: handle directory overflowsAndrew Morton
Handle the case where the variable-sized part of a rock-ridge directory entry overhangs the end of the buffer which we allocated for it. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-06-21[PATCH] rock.c: handle corrupted directoriesAndrew Morton
The bug in rock.c is that it's totally trusting of the contents of the directories. If the directory says there's a continuation 10000 bytes into this 4k block then we cheerily poke around in memory we don't own and oops. So change rock_continue() to apply various sanity checks, at least ensuring that the offset+length remain within the bounds for the header part of a struct rock_ridge directory entry. Note that the kernel can still overindex the buffer due to the variable size of the rock-ridge directory entries. We cannot check that in rock_continue() unless we go parse the directory entry's signature and work out its size.

2005-04-25[PATCH] isofs includes sanitizedAl Viro
fs/isofs includes trimmed down to something resembling sanity. Kernel-only parts of linux/iso_fs.h and entire linux/iso_fs_{sb,i}.h moved to fs/isofs/isofs.h. A lot of useless #include in fs/isofs/*.c killed. Signed-off-by: Al Viro <viro@parcelfarce.linux.theplanet.co.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

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!
