- use vsnprintf()
- rename variables to understandable "fmt", "args".
- "const char *fmt", yes.

fs/9p/vfs_inode.c
Function v9fs_get_idpool returns int, not u32. Actually it returns -1 on
errors, and these two callers check if the value is smaller than 0, which
was caught by gcc with extra warning flags. Compile tested only but should
be OK, as the value computed in v9fs_get_idpool() is also int.

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.

One of our test team hit a reiserfs_panic while running fsstress tests on
2.6.19-rc1. The message looks like :
REISERFS: panic(device Null superblock):
reiserfs[5676]: assertion !(p->path_length != 1 ) failed at
fs/reiserfs/stree.c:397:reiserfs_check_path: path not properly relsed.
The backtrace looked :

Upon debugging I found that the restart_transaction was not releasing
the path if the th->refcount was > 1.
/*static*/
int restart_transaction(struct reiserfs_transaction_handle *th,
struct inode *inode, struct path *path)
{
[...]
/* we cannot restart while nested */
if (th->t_refcount > 1) { <<- Path is not released in this case!
return 0;
}
pathrelse(path); <<- Path released here.
[...]
This could happen in such a situation :
In reiserfs/inode.c: reiserfs_get_block() ::
if (repeat == NO_DISK_SPACE || repeat == QUOTA_EXCEEDED) {
/* restart the transaction to give the journal a chance to free
** some blocks. releases the path, so we have to go back to
** research if we succeed on the second try
*/
SB_JOURNAL(inode->i_sb)->j_next_async_flush = 1;
-->> retval = restart_transaction(th, inode, &path); <<--
We are supposed to release the path, no matter we succeed or fail. But
if the th->refcount is > 1, the path is still valid. And,
if (retval)
goto failure;
repeat =
_allocate_block(th, block, inode,
&allocated_block_nr, NULL, create);
If the above allocate_block fails with NO_DISK_SPACE or QUOTA_EXCEEDED,
we would have path which is not released.
if (repeat != NO_DISK_SPACE && repeat != QUOTA_EXCEEDED) {
goto research;
}
if (repeat == QUOTA_EXCEEDED)
retval = -EDQUOT;
else
retval = -ENOSPC;
goto failure;
[...]
failure:
[...]
reiserfs_check_path(&path); << Panics here !
Attached here is a patch which could fix the issue.
fix reiserfs/inode.c : restart_transaction() to release the path in all
cases.
The restart_transaction() doesn't release the path when the the journal
handle has a refcount > 1. This would trigger a reiserfs_panic() if we
encounter an -ENOSPC / -EDQUOT in reiserfs_get_block().

free_fdtable_rc() schedules timer to reschedule fddef->wq if
schedule_work() on it returns 0. However, schedule_work() guarantees that
the target work is executed at least once after the scheduling regardless
of its return value. 0 return simply means that the work was already
pending and thus no further action was required.
Another problem is that it used contant '5' as @expires argument to
mod_timer().
Kill unnecessary fddef->timer.

Add a DESTROY operation for block device based filesystems. With the help of
this operation, such a filesystem can flush dirty data to the device
synchronously before the umount returns.
This is needed in situations where the filesystem is assumed to be clean

I never intended this, but people started using fuse to implement block device
based "real" filesystems (ntfs-3g, zfs).
The following four patches add better support for these kinds of filesystems.
Unlike "normal" fuse filesystems, using this feature should require superuser
privileges (enforced by the fusermount utility).
Thanks to Szabolcs Szakacsits for the input and testing.
This patch adds a 'fuseblk' filesystem type, which is only different from the
'fuse' filesystem type in how the 'dev_name' mount argument is interpreted.

check_partition() stops its probe once it hits an I/O error from the
partition checkers. This would prevent the actual partition checker
getting a chance to verify the partition.
So this patch lets check_partition() continue probing untill it hits a
success while recording the I/O error which might have been reported by the
checking routines.
Also, it does some cleanup of the partition methods for ibm, atari and
amiga to return -1 upon hitting an I/O error.

The current rescan_partition implementation ignores the errors that comes from
the lower layer. It reports success for unknown partitions as well as I/O
error cases while reading the partition information.
The unknown partition is not (and will not be) considered as an error in the
kernel, since there are legal users of it (e.g, members of a RAID5 MD Device
or a new disk which is not partitioned at all ). Changing this behaviour
would scare the user about a serious problem with their disk and is not
recommended. Thus for both "unknown partitions" to the Linux (eg., DEC
VMS,Novell Netware) and the legal users of NULL partition, would still be
reported as "SUCCESS".
The patch attached here, scares the user about something which he does need to
worry about. i.e, returning -EIO on disk I/O errors while reading the
partition information.

Currently a user process cannot rise its own oom_adj value (i.e.
unprotecting itself from the OOM killer). As this value is stored in the
task structure it gets inherited and the unprivileged childs will be unable
to rise it.
The EPERM will be handled by the generic proc fs layer, as only processes
with the proper caps or the owner of the process will be able to write to
the file. So we allow only the processes with CAP_SYS_RESOURCE to lower
the value, otherwise it will get an EACCES which seems more appropriate
than EPERM.

This patch adds SPU elf notes to the coredump. It creates a separate note
for each of /regs, /fpcr, /lslr, /decr, /decr_status, /mem, /signal1,
/signal1_type, /signal2, /signal2_type, /event_mask, /event_status,
/mbox_info, /ibox_info, /wbox_info, /dma_info, /proxydma_info, /object-id.
A new macro, ARCH_HAVE_EXTRA_NOTES, was created for architectures to
specify they have extra elf core notes.
A new macro, ELF_CORE_EXTRA_NOTES_SIZE, was created so the size of the
additional notes could be calculated and added to the notes phdr entry.
A new macro, ELF_CORE_WRITE_EXTRA_NOTES, was created so the new notes
would be written after the existing notes.
The SPU coredump code resides in spufs. Stub functions are provided in the
kernel which are hooked into the spufs code which does the actual work via
register_arch_coredump_calls().
A new set of __spufs_<file>_read/get() functions was provided to allow the
coredump code to read from the spufs files without having to lock the
SPU context for each file read from.

Implement .permission() in ocfs2_file_iops, ocfs2_special_file_iops and
ocfs2_dir_iops.
This helps us avoid some multi-node races with mode change and vfs
operations.

Add splice read/write support in ocfs2.
ocfs2_file_splice_read/write are very similar to ocfs2_file_aio_read/write.
