Modfs / Discussion / Open Discussion: [WAG320N] Build firmware with a modified FS

DeerHunter - 2012-02-07

Source code: http://www.mediafire.com/?qpyp3mhou91nl4m
Edit kernel/src/scripts/mod/sumversion.c and add #include <limits.h> on the
first line
File System (replace target.tgz in source code) http://www.mediafire.com/?um1
n9eo3tp33c26 ...
Modify the new target.tgz as you wish...
make clean_all
make clean
make auto .
¡Voilà!

  Maybe you forgot what to include in /src/scripts/mod/sumversion.c,
  it was include linux/limits.h
  in the makefile of hostTools I had to add -lm option to LDOPTIONS

Gnommo Modfs - 2012-02-07

Hi,
let me understand.
Are you able now to build full working bin image through this procedure?
Have you tested it?

The next step to automatically start modfs is to add to firmware:
loop.ko, ext3.ko, mbcache.ko, jbd.ko kernel module (I can compile for you)
then add losetup to /bin (you can use that is in modfs wag320 bin dir)

The generic script to found mod_image.bin on a usb device and boot modfs
is:

shares="root path where usb device are mounted"
loopdev="/dev/loop0"

ls $shares | while read line; do
image=ls $shares/$line/mod_image.bin 2>&1
if ; then
insmod $shares/$line/jbd.ko
insmod $shares/$line/mbcache.ko
insmod $shares/$line/ext3.ko
mknod $loopdev b 7 0
$shares/$line/losetup $loopdev $image

mountpath="/tmp/modfs"

mkdir -p $mountpath
mount -t ext3 $loopdev $mountpath
$mountpath/boot.sh $mountpath

These steps have to be tested one by one in order to find the correct form for
wag320n and create the right script to add to rcS.

This for example is to dgn2200 script added at the end of rcS for start modfs

!/bin/sh

basepath="/tmp/mod"
devmountpath="$basepath/dev"
modmountpath="$basepath/modfs"
modules="/lib/modules/mod"
loopdev="/dev/loop0"

sleep 45

oldfat32=""
counter=1
mkdir -p $devmountpath

while ; do

fat32=fdisk -l | grep "FAT32" | cut -d' ' -f1

if ; then

FAT32 partitions

for dev in $fat32; do
mount -t vfat $dev $devmountpath
sleep 2
image="$devmountpath/mod_image.bin"

if ; then
echo "Found on $dev"
insmod $modules/mbcache.ko
insmod $modules/jbd.ko
insmod $modules/ext3.ko
insmod $modules/loop.ko
losetup $loopdev $image
mkdir -p $modmountpath
mount -t ext3 $loopdev $modmountpath
sleep 1
exec $modmountpath/boot.sh $modmountpath
fi
echo "Not found on $dev"
umount $dev
sleep 2
done
fi

oldfat32=$fat32
counter=expr $counter + 1
sleep 1
done

I will build the modules myself ;)

I have not modified rcS yet, because it's painful to rebuild everytime I need
to test the bootscript..
Here's a ready-to-use source code tarball
(it compiles perfectly on Debian
Squeeze) (if you delete kernel/vmlnuz.a and kernel/src/vmlinux , 'make auto'
will invoke 'make menuconfig ' so you must add built-in ext3 and jbd support
to kernel (remember, ncurses-dev is needed for make menufconfig).. in fact the
Makefile tends to delete old .config kernel file)... whilst tk/apps/busybox
.config is not overwritten.. hmm.. in fact busybox .config is configurable by
make menuconfig also ..(invoke manually).
aaand.. the shell interpreter of the firmware seems to not understand an 'if'
(it says 'if [ not found' ) so I had to remove the loop ...
Also I had to make a symlink 'cut' to busybox by hand .. (it's placed in /tmp)
.. /dev is not modifiable during runtime .. so I added the nodes for
/dev/loop1 and /dev/loop2 in target.tgz before compiling ..
ah.. and this is a script that works .. (an example)
So here's the firmware (for
testing firmware images .. not end version..)

#!/bin/sh

/bin/ln -s /bin/busybox /tmp/cut

basepath="/tmp/mod" 
devmountpath="$basepath/dev" 
modmountpath="$basepath/modfs"

/bin/mkdir -p $devmountpath

    fat32=`/usr/sbin/fdisk -l | /bin/grep "FAT32" | /tmp/cut -d' ' -f1`

    /bin/mount -t vfat $fat32 $devmountpath 
    /bin/sleep 2 
    image="$devmountpath/mod_image.bin"

    /bin/mkdir -p $modmountpath 
    /bin/mount -o loop -t ext3 $image $modmountpath 
        /bin/sleep 1 
    exec /bin/echo 'Patata!'

Gnommo Modfs - 2012-02-14

Hi,
great work,
I'm glad to see your progress.
The guy who made the porting had managed the problem of /dev in a way like
this:

# Copy move /dev to ramfs to make it executable if [ -e /tmp/tmp2 ]; then rm -rf /tmp/tmp2 fi mkdir /tmp/tmp2 cp -a /dev/* /tmp/tmp2/ mount -n -t ramfs ramfs /dev cp -a /tmp/tmp2/* /dev rm -rf /tmp/tmp2

This is a snipet from boot.sh inside modfs, but I think it made something
similar also before to setup and mount the loop device.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

ok, so.. here's a totally working alpha
firmware ..(It is an alpha
release.. please use at your own risk)
and another snapshot of the used
source
If you need a mod_image.bin (for test purposes), get it here
,,
and here's what I added to /rcS (it's extremely similar to the one you
provided me )

# Copy move /dev to ramfs to make it executable 
/bin/rm -rf /tmp/tmp2 
/bin/mkdir /tmp/tmp2 
/bin/cp -a /dev/* /tmp/tmp2/ 
/bin/mount -n -t ramfs ramfs /dev 
/bin/cp -a /tmp/tmp2/* /dev 
/bin/rm -rf /tmp/tmp2

Great job!
If you want to automatically apply adsl settings like snr margin at boot

OK, I'll try to build another version with this adsl script, during the
weekend ;) .. Thx :D

done .. but adslctl will need some testing, though.

Id love to test it guys, infact im reading all this trying to make a bit more
sense of it so i can

any chance somebody can throw up just a basic how to just to get me get a
better understanding of this

Cheers

I'm very keen to see the WAG320N altered / modified. If you need anyone to
help give me a shout. Had a play mostly using the web page exploit / script
and been trying to get Telnet installed on there, but this seems a very
interesting way of accomplishing the same.

Been following this thread for a couple of weeks, hopefully people are still
working on this.

sagbohan I forgot to tell you that in order to be able to access to ssh and

this script is needed to be added to rcS.
I don't know if you have already solved in some manner.

thanks, gnommo ..
I'm going to make another build (I'm also adding the /opt folder) ..

gnommo, /etc is not writable ....¿any solution? maybe boot.sh should be
modified..

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

OK, OK .. I'll create a symlink of /etc/passwd to /tmp/etc/passwd ;)

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

DeerHunter - 2012-03-17

It seems /etc/passwd is writable ..
but sshd nor telnetd accept these credentials
here's the content of /etc/passwd after boot (with the script you gave me)

./wag320hack.sh /bin/cat /etc/passwd nobody:*:0:0:nobody:/:/bin/sh admin:admin:0:0:admin:/:/bin/sh guest:guest:0:0:guest:/:/bin/nologin

Gnommo Modfs - 2012-03-19

I didn't understand the problem on the wag320n very well, I have only
forwarded to you this question from some users that are not able to login to
ssh.
On the dgn3500 works in other way, I don't need this script that is specific
to the dgn2200 issue, because initially the root user has no password, so I
login in telnet with the root user and no password and then I set the password
through passwd command and I can save this just modified /etc/passwd file to
modfs partition, in order to recopy again it to /etc on the boot.
After that I'm able to access to ssh with root user too.
No other problems with other users, the original /etc/passwd file works well.

Other question,
it seems that on the wag320n, as on dgn3500 and despite dgn2200, it's possible
to boot mod_image.bin on ntfs , can you try to test it? In this way,you will
be able to use usb disks that can store larger files, in sight of the
