ext2: skip pages past number of blocks in ext2_find_entry (CVE-2006-6054)

2007-01-09T02:23:34+00:00

This one was pointed out on the MOKB site: http://kernelfun.blogspot.com/2006/11/mokb-09-11-2006-linux-26x-ext2checkpage.html If a directory's i_size is corrupted, ext2_find_entry() will keep processing pages until the i_size is reached, even if there are no more blocks associated with the directory inode. This patch puts in some minimal sanity-checking so that we don't keep checking pages (and issuing errors) if we know there can be no more data to read, based on the block count of the directory inode. This is somewhat similar in approach to the ext3 patch I sent earlier this year. Signed-off-by: Eric Sandeen Signed-off-by: Adrian Bunk

[PATCH] Fix ext2 readdir f_pos re-validation logic

2006-03-16T00:31:51+00:00

This fixes not one, but _two_, silly (but admittedly hard to hit) bugs in the ext2 filesystem "readdir()" function. It also cleans up the code to avoid the unnecessary goto mess. The bugs were related to re-valiating the f_pos value after somebody had either done an "lseek()" on the directory to an invalid offset, or when the offset had become invalid due to a file being unlinked in the directory. The code would not only set the f_version too eagerly, it would also not update f_pos appropriately for when the offset fixup took place. When that happened, we'd occasionally subsequently fail the readdir() even when we shouldn't (no real harm done, but an ugly printk, and obviously you would end up not necessarily seeing all entries). Thanks to Masoud Sharbiani who noticed the problem and had a test-case for it, and also fixed up a thinko in the first version of this patch.

ext2: trivial indentation fix.

2006-01-11T00:38:27+00:00

This memset() line was indented with seven spaces, this patch fixes it to use a tab instead. Yes, very trivial but it's the third time I have to look at this line.. Signed-off-by: Luiz Capitulino Signed-off-by: Adrian Bunk

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!
