FATAL ERROR:failed to read fragment table

Trying to extract a squashfs image which was extracted from a firmware bin but i get this error :

|read_fragment_table: failed to read fragment table block
FATAL ERROR:failed to read fragment table

i dont think the file is corrupted since it was extracted directly from the manufacture's firmware bin
maybe some trick ? that could be added to sasquatch if discovered

uses outdated version of squashfs-tools

sasquatch is currently using an old version of squashfs-tools, which contains the bug described here: plougher/squashfs-tools#125 that was fixed in a later version.

https://github.com/ReFirmLabs/binwalk depends on this package, and after it (silently) failed to extract a squashfs binary while running in a docker container with an almost infinite open file limit, I tracked the upstream issue to here.

In summary: just bump the squashfs version in the build script

Unable to extract squashfs

I am attempting to recover data from a flash chip removed from a proprietary device. I've dumped the chip and stripped out the OOB data.

Binwalk finds multiple squashfs partitions.

Sasquatch -s looks hopeful:

filesystem newer than what sasquatch 4.3 can handle?

I'm working with a squashfs-encrypted file that was created June 14, 2012:

ONKAVR0003_MA00MAMAMA00SAM7MA.of3 <- ignore the file extension

It's one of three files that Onkyo (A/V receiver mfgr) uses for firmware updates.

This is what I get when trying to display superblock info (also when I try to extract):

$ sasquatch -s ONKAVR0003_MA00MAMAMA00SAM7MA.of3

SquashFS version [64690.53089] / inode count [263635247] suggests a SquashFS image of a different endianess
Non-standard SquashFS Magic: BW
Reading a different endian SQUASHFS filesystem on ONKAVR0003_MA00MAMAMA00SAM7MA.of3
Filesystem on ONKAVR0003_MA00MAMAMA00SAM7MA.of3 is (45820:25039), which is a later filesystem version than I support!

Anyone one to take a stab at this? I can email the zipped file containing the three *.of# files.

make: *** [Makefile:298: sasquatch] Error 1

Multiple bugs from fuzzing

I've been fuzzing sasquatch (in particular the fork by @gcanalesb, which fixes a number of bugs I found in this release) and ran into a number of crashes which persisted. There appear to be a few checks missing where values are passed to malloc() without validation, and at least one case that causes out-of-bounds access.

I've got 68 crashes, though I haven't run through them all to check what's a duplicate and what's not. From what I can tell, there are at least 4 crash sites (mostly in fragment table parsing), but I've honestly not done a lot of manual checking.

I've attached an archive with valgrind and strace output from each crash, each prepended with the filename which caused the crash. Unfortunately I can't upload the full archive of sample files here, as it ends up being a 150MB archive. I'll find an alternative upload location and post it as a comment shortly.

Debian / gcc / g++ gcc (Debian 10.2.0-15) 10.2.0 : fails to compile

On compilation, LD complains about multiple references to "verbose" at linking

Easy to solve, ensure in the patch that :

verbose is extern in sasquatch/squashfs4.3/squashfs-tools/error.h
add "int verbose;"
in unsquashfs.c

Bashism in build.sh

The UID check appears to be a bashism, as it doesn't run under sh

e.g.

$ if [ "$UID" == "0" ]
then
    SUDO=""
else
    SUDO="sudo"
fi> > > > >
sh: 6: [: unexpected operator

(actually, the problem is with the ==, which only works in double brackets)

Small changes so that the build.sh runs on the latest of Kali Linux

So over the past few days I've had some trouble getting this to build on Kali Linux but have resolved it simply by running

CFLAGS=-fcommon ./build.sh

Rather than

./build.sh

If anyone else has been having issues like I have hopefully this at least gives them a easy to find fix for it.

The patch doesn't apply to squashfs-tools-4.4

Is there any chance to fix the patch so it would be applied to squashfs-tools-4.4 ?

./build.sh failed on Kali

failed to read uid/gid table

I am curently trying to extract a SquashFS filesystem of a firmware that I am working with for quite a while now. I had a lot of issues until this point but I managed to get a SquashFS file that looked promising to me.

When I first tried to extract it with the unsquashfs utility I got an error message. I guess this is a vendor hacked version.
So I tried to use sasquatch instead but I still get the following error message:
SquashFS version [4.0] / inode count [1957] suggests a SquashFS image of the same endianess Parallel unsquashfs: Using 1 processor read_uids_guids: failed to read id table block FATAL ERROR:failed to uid/gid table
Apparently there is something wrong with the id tables. Is there anything that I can do to work around this problem or is it not possible at all to extract the files like this?

Something that I also noticed is that the string ELF keeps popping up over the file system image.

Edit:
When I use the -s option of the unsquashfs utility I receive the following information:

Found a valid SQUASHFS 4:0 superblock on 0.squashfs. Creation or last append time Wed Nov 28 09:29:14 2018 Filesystem size 14015771 bytes (13687.28 Kbytes / 13.37 Mbytes) Compression lzo Block size 131072 Filesystem is exportable via NFS Inodes are compressed Data is compressed Uids/Gids (Id table) are compressed Fragments are compressed Always-use-fragments option is not specified Xattrs are compressed Duplicates are removed Number of fragments 69 Number of inodes 1957 Number of ids 5

loSame issue on Kali/Debian with `gcc (Debian 10.2.1-6) 10.2.1`

Same issue on Kali/Debian with gcc (Debian 10.2.1-6) 10.2.1

Both solutions did not work for me.
@Jegeva I changed in sasquatch/squashfs4.3/squashfs-tools/error.h int verbose; to extern int verbose; and added in unsquashfs.c int verbose; after int user_xattrs = FALSE;.
Are these steps right?

Afterwards I get these errors:

Build script downloading squashfs.4.3.tar.gz as HTML.

I don't know why, but when using this build script it fails. Upon investigating I found out the squashfs gzip files can't be extracted (tar zxvf output says "not a gzip file")

Then I did "file squashfs.4.3.tar.gz" and found out wget downloads it as HTML.

After downloading the file and applying the patch mannualy, I compiled it just fine.

script url to squashfs4.3 no longer exists

The link in the build script, no linger exists.
Where the heck is squashfs4.3 located these days?

https://downloads.sourceforge.net/project/squashfs/squashfs/squashfs4.3/squashfs4.3.tar.gz

I've done something wrong

What version of debian/ubuntu can you build this on?

Different-endian filesystem not extractable

Binwalk says the following:

Squashfs filesystem, big endian, version 4.0, compression:xz, size: 15229650 bytes, 6054 inodes, blocksize: 65536 bytes, created: 1970-06-26 06:27:30

Alas, sasquatch fails at extracting the files:

sasquatch -major 4 -minor 0 -be -c xz -f ../mmcblk0p1
Non-standard SquashFS Magic:
Reading a different endian SQUASHFS filesystem on ../mmcblk0p1
FATAL ERROR:Block size or block_log too large. File system is corrupt.

I know the filesystem is not corrupt, so I can only hazard a guess that sasquatch gets the endianness wrong on one or another value.

License?

Hi,

First of all, thanks for your patch!

There is no License in the repo, so it is unclear for people wanting to reuse your work to know to which extent they can.

In particular, I am looking to make it available as a package on NixOS (NixOS/nixpkgs#66600).

Cheers,

please do not pollute my filesystem

You should not copy files over into my filesystem, especially in a script called build.sh. I could understand if install.sh did this.

Merge #18 for solving problem on C imports

#18 solves a library error which prevents from installing. I tested it, works perfectly.

#16 seeems to solve the same issue but I didn't test it.
