You should print out the page->mapping->host->i_ino in this message
and then you can possibly examine the filesystem to see if it is
a corrupt block allocation, or possibly random garbage in the block.

Hmm, is this filesystem formatted with 64BIT? We shouldn't be getting
64-bit block numbers otherwise.

Confirm this issue happens after ~30secs of ltp fsstress.
This happens because of error in ext4_get_block()
ext4_get_block()
{
...
ret = ext4_get_blocks_wrap(handle, inode, iblock,
max_blocks, bh_result, create, 0);
if (ret > 0) {
r2 = ret;
bh_result->b_size = (ret << inode->i_blkbits);
# Setting b_size, if ret > 1 then bh_result is broken because
# b_size must always be equal to FS logical block size(1<<inode->i_blkbits)
ret = 0;
}
}
Later
submit_bh()
{
...
bio = bio_alloc(GFP_NOIO, 1);
bio->bi_sector = bh->b_blocknr * (bh->b_size >> 9);
# OOPs ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
# this code assumes what b_size == FS logical block size.
# This result in accessing beyond end of block device.
bio->bi_bdev = bh->b_bdev;
bio->bi_io_vec[0].bv_page = bh->b_page;
bio->bi_io_vec[0].bv_len = bh->b_size;
bio->bi_io_vec[0].bv_offset = bh_offset(bh);

Hi Andreas,

Will do thanks.

I'm using:
mke2fs 1.40.8 (13-Mar-2008)
Using EXT2FS Library version 1.40.8
(the one from debian unstable)
and format like this:
/sbin/mkfs.ext3 -E test_fs /dev/sdb
Just want to note (because of current vger problems) that Dmitri
confirmed the symptom (with fsstress+fallocate patch) and offered an
analysis.

I don't think that's quite right.
this bh is a dummy bh, right, which just gives us info on the mapping.
static int ext4_get_block(struct inode *inode, sector_t iblock,
struct buffer_head *bh_result, int create)
{
handle_t *handle = ext4_journal_current_handle();
int ret = 0, started = 0;
unsigned max_blocks = bh_result->b_size >> inode->i_blkbits;
for starters, ext3 does exactly the same thing.
Also look for example at get_more_blocks():
map_bh->b_state = 0;
map_bh->b_size = fs_count << dio->inode->i_blkbits;
...
ret = (*dio->get_block)(dio->inode, fs_startblk,
map_bh, create);
or do_mpage_readpage():
nblocks = map_bh->b_size >> blkbits;
....
if (block_in_file < last_block) {
map_bh->b_size = (last_block-block_in_file) <<
blkbits;
if (get_block(inode, block_in_file, map_bh, 0))
goto confused;
*first_logical_block = block_in_file;
}
the bh->b_size can be more than a block; in this case it's not a problem.
maybe some buffer tracing would be in order?

So this is WARN_ON(bh->b_size != blocksize);
What is b_size in this case?

I did not collected it on this run, but I typically get things like:
blocksize 132112384 != 4096

FS block size, because this page pinned bh (it comes from page_buffers(page)), but
not dummy bh which may comes from {write,read}pages or direct_IO.
Page's bh i_size must always be equal to fs blocksize.
This bh always constructed via following construction
if (!page_has_buffers(page))
create_empty_buffers(page, 1<<inode->i_blkbits, flags)
So page's bh->b_size was inited with right value from very beginning, but
apparently somewhere this size was changed
I guess i've localized buggy place, at least it's looks strange.
ext4_da_get_block_prep ()
{
...
BUG_ON(create == 0);
BUG_ON(bh_result->b_size != inode->i_sb->s_blocksize);
ret = ext4_get_blocks_wrap(NULL, inode, iblock, 1, bh_result, 0, 0);
#Here ext4_get_block_write called with max_blocks == 1 ^^^^^
...
if (ret > 0) {
bh_result->b_size = (ret << inode->i_blkbits);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
## I don't understand this place. I hoped what (ret <= max_blocks) must always
##be true true. But after I've add debug info printing I've got following result.
ret = 0;
}
...
}
Some times I've seen following ,message
bh= {state=0,size=114688, blknr=18446744073709551615 dev=0000000000000000,count=0}, ret=28
And because it was page-cache's bh later this result in WARNING.

Is that a fallocate space ?. For falloc space we can return values
greater than max_blocks. ext4_ext_get_blocks was made to return >0
for a read on prealloc space to ensure delalloc doesn't reserve space
for the same. I guess we need to make sure we don't return more than
max_blocks. Can you try the patch below

Ok Warning has gone, but resulted bh still incorrectly filled.
I've found what function ext4_da_get_block_prep() return bh witch
is !mapped and !delayed, which is prohibited because it is always called with
create != 0. BH debug info at the end of this function result in following msg
BH={state=0, size=4096, blknr=18446744073709551615,dev=0000000000000000,
count=0} block =288 ret=1
Later this incorrectly filled bh result in BUG_ON triggering

As Dmitri mentioned in the previous mail if the buffer head is not
marked as delayed or new, in __block_prepare_write after get_block
we would do a ll_rw_block(READ, 1, &bh); and that will result in BUG_ON.

bh is not marked as new? Oh that's right. Perhaps we should mark the bh
as unwritten, xfs does that. __block_prepare_write() will avoid do
ll_rw_block() if the bh is unwritten.

I think the root cause is here, ext4_get_block_wrap() could returns
number of blocks greater than the caller is asking for, and set the
mapped/allocated bytes in the bh->b_size.
The problem is that the for buffered IO (without delaloc) get_block()
via ext4_get_block_wrap() at write_begin time makes sure the buffer is
mapped, so later at the writepage()->block_write_full_page() time, it
never hits the branch the WARN_ON(bh->b_size != blocksize) in
__block_write_full_page(), even if the b_size is previously changed to
greater than the blocksize, by ext4_get_block_wrap() at the write_begin
time.
This warning is only seen with delayed allocation because we did a
get_block() (via ext4_da_get_block_prep()) look up with 1 block at a
time, but the bh->b_size is storing the length of the whole extent,
since ext4_get_block_wrap() could returns number of blocks greater than
the caller is asking for.
static int __block_write_full_page(struct inode *inode, struct page *page,
get_block_t *get_block, struct writeback_control *wbc)
{
....
if (!buffer_mapped(bh) && buffer_dirty(bh)) {
WARN_ON(bh->b_size != blocksize);
err = get_block(inode, block, bh, 1);
if (err)
goto recover;
if (buffer_new(bh)) {
/* blockdev mappings never come here */
clear_buffer_new(bh);
unmap_underlying_metadata(bh->b_bdev,
bh->b_blocknr);
}
}
I think the fix probabaly should enforce
ext4_get_blocks_handle()/ext4_ext_get_block() never map/allocate the
number of blocks that more than what is asking for..
