- ext3_dx_find_entry() exit with out setting proper error pointer - do_split() exit with out setting proper error pointer it is realy painful because many callers contain folowing code: de = do_split(handle,dir, &bh, frame, &hinfo, &retval); if (!(de)) return retval; <<< WOW retval wasn't changed by do_split(), so caller failed <<< but return SUCCESS :) - Rearrange do_split() error path. Current error path is realy ugly, all this up and down jump stuff doesn't make code easy to understand.

Many struct inode_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

Return -ENOENT from ext[34]_link if we've raced with unlink and i_nlink is 0. Doing otherwise has the potential to corrupt the orphan inode list, because we'd wind up with an inode with a non-zero link count on the list, and it will never get properly cleaned up & removed from the orphan list before it is freed.

I've been using Steve Grubb's purely evil "fsfuzzer" tool, at http://people.redhat.com/sgrubb/files/fsfuzzer-0.4.tar.gz Basically it makes a filesystem, splats some random bits over it, then tries to mount it and do some simple filesystem actions. At best, the filesystem catches the corruption gracefully. At worst, things spin out of control. As you might guess, we found a couple places in ext4 where things spin out of control :) First, we had a corrupted directory that was never checked for consistency... it was corrupt, and pointed to another bad "entry" of length 0. The for() loop looped forever, since the length of ext4_next_entry(de) was 0, and we kept looking at the same pointer over and over and over and over... I modeled this check and subsequent action on what is done for other directory types in ext4_readdir... (adding this check adds some computational expense; I am testing a followup patch to reduce the number of times we check and re-check these directory entries, in all cases. Thanks for the idea, Andreas). Next we had a root directory inode which had a corrupted size, claimed to be > 200M on a 4M filesystem. There was only really 1 block in the directory, but because the size was so large, readdir kept coming back for more, spewing thousands of printk's along the way. Per Andreas' suggestion, if we're in this read error condition and we're trying to read an offset which is greater than i_blocks worth of bytes, stop trying, and break out of the loop. With these two changes fsfuzz test survives quite well on ext4.

When a filesystem decrements i_nlink to zero, it means that a write must be performed in order to drop the inode from the filesystem. We're shortly going to have keep filesystems from being remounted r/o between the time that this i_nlink decrement and that write occurs. So, add a little helper function to do the decrements. We'll tie into it in a bit to note when i_nlink hits zero.

由 Neil Brown 提交于
The inode number out of an NFS file handle gets passed eventually to ext3_get_inode_block() without any checking. If ext3_get_inode_block() allows it to trigger an error, then bad filehandles can have unpleasant effect - ext3_error() will usually cause a forced read-only remount, or a panic if `errors=panic' was used. So remove the call to ext3_error there and put a matching check in ext3/namei.c where inode numbers are read off storage.

This patch fixes illegal __GFP_FS allocation inside ext3 transaction in ext3_symlink(). Such allocation may re-enter ext3 code from try_to_free_pages. But JBD/ext3 code keeps a pointer to current journal handle in task_struct and, hence, is not reentrable.

Henrik Grubbstrom noted: The 2.6.10 ext3_get_parent attempts to use ext3_find_entry to look up the entry "..", which fails for dx directories since ".." is not present in the directory hash table. The patch below solves this by looking up the dotdot entry in the dx_root block. Typical symptoms of the above bug are intermittent claims by nfsd that files or directories are missing on exported ext3 filesystems. cf https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=3D150759 and https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=3D144556 ext3_get_parent() is IMHO the wrong place to fix this bug as it introduces a lot of internals from htree into that function. Instead, I think this should be fixed in ext3_find_entry() as in the below patch. This has the added advantage that it works for any callers of ext3_find_entry() and not just ext3_lookup_parent().

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!
