Hi,
I am implementing recovery mechanism where i need to flash/update
squashfs volume.
But so far failed
Using the following ubi configuration to create image:
[sysfs_volume]
mode=ubi
image=machine-image.squashfs
vol_id=0
vol_type=dynamic
vol_name=rootfs
vol_size=55MiB
[md_rootfs_volume]
mode=ubi
image=machine-image.squashfs.verity
vol_id=1
vol_type=dynamic
vol_name=md-rootfs
vol_size=1MiB
[sdatafs_volume]
mode=ubi
image=sdata.squashfs
vol_id=2
vol_type=dynamic
vol_name=sdatafs
vol_size=8MiB
[md_sdatafs_volume]
mode=ubi
image=sdata.squashfs.verity
vol_id=3
vol_type=dynamic
vol_name=md-sdatafs
vol_size=1MiB
[cache_volume]
mode=ubi
vol_id=4
vol_type=dynamic
vol_name=cachefs
vol_size=154MiB
[systemrw_volume]
mode=ubi
vol_id=5
vol_type=dynamic
vol_name=systemrw
vol_size=6MiB
[persist_volume]
mode=ubi
vol_id=6
vol_type=dynamic
vol_name=persist
vol_size=6MiB
[usrfs_volume]
mode=ubi
image=usrfs.ubifs
vol_id=7
vol_type=dynamic
vol_name=usrfs
vol_flags = autoresize
========
The failure happens when updating "rootfs" volume 0 using
ubiupdatevol, which is our root file system, using squashfs (fastmap
enabled)
The size of new " machine-image.squashfs " is 43257856.
Using "ubiupdatevol" in recovery mode, no errors observed:

usually squashfs has a blocksize of 1k or 4k. So block 0x785a5a is out
of bounds.

There seem to be many other components involved.
Is the squashfs image actually correct?

SquashFS has a device block size that is either 1k or 4k that is only relevant
for I/O transfers. The actual block size is between 4k to 1M (defaults to 128k).
The data blocks also have no headers or checksums.
Meta data (inodes, directory entries, tables) is chopped in 8k chunks and stored
possibly compressed with a 2 byte header.
Once compressed, blocks can have any size and there is absolutely no requirement
for alignment. Inodes (or in this case the fragment table) can literally point
just anywhere between the super block and the inode table.

SquashFS tries to read a fragment block located some ~7.5 MiB after the
super block (0x785a5a) with a compressed size of 54964 bytes (0xd6b4).
For a ~41 MiB SquashFS image this sounds plausible.
Uncompressing fails, so the location that the fragment table points to does
not contain a valid zlib stream.
Interestingly, the inode, directory and fragment tables seem to be at least
partially readable. Accessing the root inode and walking through the tree
seems to work, since there are no other SquashFS error messages.
*Assuming* that it is not the data that is broken, *if* there are no xattrs
and NFS export tables, the fragment table is pretty much at the very end.
Maybe the filesystem is partially chopped off at the end?
Have you tried dumping the SquashFS image from the UBI volume and extracting it?
(E.g. using unsquashfs, rdsquashfs or sqfs2tar which generate more useful error
messages about what actually broke)
Regards,
David

I would try to either use dd on the ubiblock which you are trying to mount,
or cat on the underlying ubi volume and pipe it into a file.
It shouldn't matter if there's extra garbage at the end. The SquashFS super
block specifies the exact size of the image.

David

I now have similar problem with different image, in our system we have
rootfs ubi and recovery ubi.
I created a new recovery ubi and flashed it with "fastboot flash" command.
Tried to boot into recovery mode and got similar error that i got from
rootfs ubi:

From your logs you seem to be getting the same errors as for mounting
the image.

Browsing through the last mail, saw that you generate the image with
the -noI option, which means that inodes are uncompressed. So they
could in theory be corrupted but still partially readable, leading to
accessing the data area at off locations or trying to access non existent
fragments.
Can you try it without the -noI option? If the meta data gets corrupted,
you should get an error about that before the kernel tries to access the
Could you try out the following, to check if UBI causes the damages to
your SquashFS image:
- Create a fresh SquashFS image
- Verify that you can also unpack the original image again without errors
- Write it to ubiblock
- Dump it back from the ubiblock
- Check again on the dumped image
- compare checksums of the original and the dumped image
Again, there are a bunch of non-standard messages in your kernel boot log.
Do you use any 3rd party out-of tree modules that could potentially be
interfering?
Regards,
David
