ipset does not work on android #107

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I'm using several HTC's android phones and trying to port this.
All the binaries are not stripped.
Kernel modules are compiled and installed without any problems. 
After comment out "-Wl,--no-undefined"(in android source/ndk), ipset's
libraries can be compiled, but can't be loaded saying can't find some
functions.
Well, it seems that ipset's library will look for some function entries on
ipset, strange design.
Since libc(bonic) in android doesn't implement this feature, is it easy to
make ipset user space binaries a single executable?

Patched ipset and make it a single executable(Simply call xxxx_init in main). 
Now it
works.

After an afternoon now it seems to work on my G4. And it will soon available for
other models.
I can see logs now.

But unfortunately, my home gateway is the common one which is reported not 
working in
certain LANs.
