Subject: [RFC,PATCH] 64-bit support for e2fsprogs

This is my incomplete current 64-bit e2fsprogs patchset for review and
comment (not inclusion). Only lib/ext2fs/, misc/mke2fs.c, and e2fsck/
have been converted to 64-bit interfaces so far (and those not
completely). As of this patch set, mke2fs can create a file system
with > 2^32 blocks. However, it can't be mounted due to invalid
checksums on the group descriptors. :)

This series is based on the 64-bit patches by Ted T'so and Jose
R. Santos. It includes:

* Two housekeeping patches (workaround make check error, fix warnings)
* 64-bit bitops and bitmaps
* Conversion of all of e2fsprogs to 64-bit bitmap interfaces
* Partial conversion of e2fprogs to other 64-bit interfaces
* Miscellaneous 64-bit bug fixes

Use the following mke2fs command to produce a file system with more
than 2^32 blocks:

$ mke2fs -t ext4 -O 64bit -b 4096 -N 200000 <device>

These patches apply against the pu branch, commit ID:

6db77ec039ff241dab0f1e267fabcfa814fbaf4c

All commits pass "make check" on my machine.

-VAL

Valerie Aurora Henson (17):
Disable tst_refcount - doesn't compile, don't know why
Squash warnings
Add 64-bit bitops
Implement 64-bit "bitarray" bmap ops
Convert libext2fs to 64-bit bitmap interface
Convert mke2fs to new bitmap interface
Convert e2fsck to new bitmap interface
Turn on new bitmaps in e2fsck and mke2fs
Add progress bar for allocating block tables - takes forever on large
signed int -> blk64_t to fix bugs at 2^31 - 2^32 blocks
Fix overflow in calculation of total file system blocks
Add ext2fs_block_iterate3 (from Ted)
Support 48-bit file acl blocks
super->s_*_blocks_count -> ext2fs_*_blocks_count()
Convert to inode/block/bitmap/table loc()/loc_set() functions
ext2fs_block_alloc_stats -> ext2fs_block_alloc_stats2
Convert to 64-bit IO

Ted, this actually exposes a bug in mke2fs, in that the device size to
"type" detection code is broken. Val was reporting that running on a
16TB device would pick the "floppy" type and try to use 1024-byte blocks
and 1 inode per 1024 bytes, which would exceed the 2^32 inode limit.
Hence the current requirement to specify a 4096-byte blocksize and a
hard limit on the number of inodes.

Since we're going to the expense of allocating a 1-pointer data structure,
we may as well make it useful by adding a magic value in there that can
be verified later and catch code bugs or corruption.

Then use a simple accessor function ba_private_to_bitarray() to verify the
pointer magic and return the bitarray pointer directly. That would remove
the direct use of "ext2fs_ba_private" in the majority of the code.

Would it also be worthwhile to store the size of the bitarray in the
ba_private_struct for verification?

As a general rule, I dislike types that are pointers, as it isn't clear
from looking at this code if you are passing "bmap" by reference or a
copy.

Is this worth a better error than "EINVAL"? In general, anything that
returns "errcode_t" can have a very specific error return value as
defined in lib/ext2fs/ext2_err.et.in. This is true of all of these
functions that return EINVAL.

Hmm, how do you distinguish between EINVAL and an actual start value here?

To be "fail safe" this should probably prefer to believe there is a 32-bit
bitmap (i.e. what is used in all existing applications/deployments) instead
of a 64-bit bitmap. Failing that, is there a reason the 32-bit bitmap
cannot register a ->clear_bmap() method itself, and this code can never
fail?

Similarly, I don't see how the caller of this code can distinguish between
EINVAL and (what is expected to be a boolean) whether the entire bitmap
range is clear or not.

Does it make sense to only update the progress periodically instead of for
every group? Since this is a memory operation, I suspect the console
output slows it down noticably, and would spew a ton of garbage into
console logs and such. Something like:

for (i = 0; i < fs->group_desc_count; i++) {
if (i & 256 == 255)
progress_update(&progress, i);
retval = ext2fs_allocate_group_table(fs, i, (ext2fs_block_bitmap64) fs->block_map);
if (retval)
return retval;
}
progress_close(&progress);

These appear to be defects in the base code and should be landed ASAP
(as int -> blk_t) independently of this patch series.

Casting the first value to __u64 should be enough.

This should really be part of patch 05/17 because that is where "real_end"
is turned into a 64-bit value.

There is a similar fix missing from ext2fs_allocate_inode_bitmap() (even
though there isn't any support for 64-bit inode numbers as yet.

Several of these changes should probably be part of the previous patch,

Does e2fsck validate the ACL block number is within the filesystem
limits when it is checking the filesystem?

Along with changes like this (and the similar ACL fix) I'd prefer that we
rename the old superblock field to be "s_block_count_lo" and put a comment
there referencing the accessor functions so that compilation will fail
and it is clear what needs to be fixed.

As you can see from this patch, even though ext2fs_blocks_count() predates
the 64-bit patches, it isn't used very widely. Landing other patches
to e2fsprogs may run the risk of only accessing the low 32 bits of the
size/count/acl/etc because they were developed before 64-bit support
was added.

Since it isn't yet common to be able to test > 32-bit blocks
these bugs may go unnoticed for some time. It would be nice to be able
to test 64-bit support easily with e2fsprogs. Maybe truncate file
to > 16TB in size (abort if underlying filesystem isn't able to do this),
use "lazy_bg" or equivalent to avoid writing many GB of data into the
sparse file, then run e2fsck on it after putting some files at the end.
This could probably be done by the "script" support in "make check".

Similarly, renaming bg_block_bitmap to bg_block_bitmap_lo (et. al.)
would catch tools that are broken on 64-bit filesystems.

16TB using a 4k block size is 2**32 blocks, so it's not surprising
it's screwing up and picking the floppy type. I assume it's only
looking at fs_param->s_blocks_count and not fs_param->s_blocks_count_hi.

It also needs to cap the number of inodes in case of very large
filesystems to make sure we don't overflow 2**32 inodes, yes.

I'm not sure I would call this a bug in the existing mke2fs code, as
much as it is simply that the 64-bit support is not yet complete. Or
am I missing something in what you complaining about?

I'll go back and look at that, but in general it's hard to transition
from ext2fs_block_iterate2() ext2fs_block_iterate3() independently
because the iterate function has to convert to 64-bit at the same time
(or else you have to write complex and ugly glue code which lives for
exactly one revision).

Heh, I just assumed progress already did that. How about making the
unit of progress proportional to the total number of tables? Say,
update progress every thousandth.

Also, this is kind of obnoxious - I just cut and paste
ext2fs_allocate_tables() from its original home because the progress
routines aren't exported. It may be smarter to export them (for
internal use only) and put the progress into ext2fs_allocate_tables().

Me too, but that's the way they are...

The deal here is that the caller of the new_bmap() op has already
allocated the ext2fs_generic_bitmap64 (which is a typedef'd pointer to
struct) itself. This function is only allowed to fill in members of
the bitmap; in particular, the private data pointer. So initially it
seems like it should take a pointer to an ext2fs_generic_bitmap64, but
in actuality that's an invitation to disaster - e.g., this function
should not free the generic bitmap structure on failure, only things
that it has allocated.

In Ted's design, the assumption is 64-bit and the check is for 32-bit.
Having the 32-bit code use the new bmap_ops() interface seems to me to
be overkill - we just want to abandon the old 32-bit code as much as
possible, not rewrite it to new interfaces.

Actually, the main reason I hard-code the inodes is to speed up file

That's a question I have: Should the 64-bit port have partial support
for 64-bit inodes? Supporting 64-bit inodes is enough effort and risk
(especially in terms of glue code to convert back to 32-bit versions)
that I think it makes sense to wait until we know more about what they
will look like and have concrete plans to support them.

Unfortunately, ext4 doesn't support a file this big so you'd have to
deliberately put your e2fsprogs tree on XFS or something like that for
this automatic check to actually help - not a terribly common
situation for an e2fsprogs developer. (I'm doing all my testing on
sparse files on XFS, which definitely chafes - nothing wrong with XFS,
just kind of annoying that I can't self-host e2fsprogs development.)

Hummm... Would it work to use LVM to glue together two loopback
devices backed by files that sum to just over 16TB?

Is it?

if (flexbg_size) {
int prev_block = 0;
if (group && fs->group_desc[group-1].bg_block_bitmap)
prev_block =
fs->group_desc[group-1].bg_block_bitmap;
start_blk = flexbg_offset(fs, group, prev_block, bmap,
0, rem_grps, 1);
last_blk = ext2fs_group_last_block(fs, last_grp);
}

bg_block_bitmap is only a __u32, and that's what we assign to prev_block.

Just a quick scan, but isn't this just a relative block in the group?

oh, sigh, I was thinking of blk_t as a 64 bit here already :)

No, this is fine. I'll take the patch and merge it into maint.

Note, what I'm going to try to do is to take entire patches of yours
at once, although in some cases they will be applied to different
branches (or split into different patches).

The goal will be to not disturb things too badly if you do any further
work on the patch series, since git-rebase should be smart enough.
However, it might be a good idea for you to set a tag on what you've
pushed so far, and to save everything past that point as diffs in case
git rebase doesn't work out for whatever reason.

Hopefully while I'm in Japan and/or over Thanksgiving weekend I'll
have enough time to merge all of these patches into mainline. (I'll
probably miss next week's conference call as well since I'll be in
Tokyo, BTW. If someone can take notes during the call, or at least
for anything that needs my attention, I'd appreciate it.)

Or you could play with devicemapper, see
Documentation/device-mapper/zero.txt:

One very interesting use of dm-zero is for creating "sparse" devices in
conjunction with dm-snapshot. A sparse device reports a device-size
larger than the amount of actual storage space available for that
device. A user can write data anywhere within the sparse device and read
it back like a normal device. Reads to previously unwritten areas will
return a zero'd buffer. When enough data has been written to fill up the
actual storage space, the sparse device is deactivated. This can be very
useful for testing device and filesystem limitations.

To create a sparse device, start by creating a dm-zero device that's the
desired size of the sparse device. For this example, we'll assume a 10TB
sparse device.

TEN_TERABYTES=`expr 10 \* 1024 \* 1024 \* 1024 \* 2` # 10 TB in sectors
echo "0 $TEN_TERABYTES zero" | dmsetup create zero1

Then create a snapshot of the zero device, using any available
block-device as the COW device. The size of the COW device will
determine the amount of real space available to the sparse device. For
this example, we'll assume /dev/sdb1 is an available 10GB partition.

echo "0 $TEN_TERABYTES snapshot /dev/mapper/zero1 /dev/sdb1 p 128" | \
dmsetup create sparse1

This will create a 10TB sparse device called /dev/mapper/sparse1 that
has 10GB of actual storage space available. If more than 10GB of data is
written to this device, it will start returning I/O errors.

I agree, in general, but this kind of wordsize overflow bug is easy to
miss, and we may as well only have to figure out the bug once.

Speaking of which, I'll also miss next week's call due to travelling.

I've just checked the following into e2fsprogs git tree.

commit a057b2332f5780b71018630f18f2619480118c5d
Author: Theodore Ts'o <[email protected]>

Fix various signed/unsigned gcc warnings

Some of these could affect filesystems between 2^31 and 2^32-1 blocks.

Thanks to Valerie Aurora Henson for pointing out the problems in
lib/ext2fs/alloc_tables.c, which led me to do a "make gcc-wall"
scan over the source tree.
