netfilter kernel module questions
Mihai Campean
As I understood from the few posts available on this group about the
netfilter kernel module, this module is currently not available in the
android kernel. I am a noob to this part of Android so please bear
with me and my questions :).
The first question is where I would find a list of what kernel
version each version of Android uses - I need this to determine which
version of Android might have the netfilter module installed in the
kernel.
The second question is, how would one go about and introduce the
netfilter module in an Android kernel that doesn't have it - if that's
an option.
The reason why I am asking these questions is that, I need to write
an NDK shared library that uses the netfilter hooks for packet
mangling and filtering, or to use the conntrack-tools libraries in
order to provide a packet filtering interface for a firewall.
Any help and guidance would be very much appreciated, thank you.
Have fun,
Mihai

implement "tether" function.
Certainly, you can not find this module in images released by
HTC...until now.

a certain kernel module installed?

module configured on. The default kernel configuration does not have
'netfilter' built-in. You can add it while doing 'menu-config'. In the
kernel source codes there does have netfilter implementations in \net
\netfilter folder.

And you can use lsmod to find if there is certain module installed.

From what I know lsmod command requires root access.
Is there a programmatic way to find out? And if yes, could it be
available on not rooted phones?
PS: I guess it should be something available in /proc. I will search
further, but any start point would help.
Thanks,
Dan

No it does not.

Yes there is, 'cat /proc/modules'
