[android-developers] Re: ndk-build and stdio problems (Android 2.2.1)

2011-11-30 Thread Adam Bell
Seems in particular that close(0), close(1), and close(2) cause a process 
hang when fork() is used.
When built with Android code under the external directory, everything works 
as expected.

[android-developers] ndk-build and stdio problems (Android 2.2.1)

2011-11-21 Thread Adam Bell
I am working with some large open source projects and some smaller
custom C code.  I can successfully compile and link these using the
ndk-build API even when linking against shared object files within the
Android tree.  I get functional shared object files and executables
for the Android platform.  However, it seems that when the
applications are built as stand alone (meaning outside the Android
source code tree using only ndk-build)  the stdio functions do not
operate properly.  When the same code is placed under external within
the Android source code tree and built with Android, the stdio
functions work exactly as expected.

I have tried building with ndk r4 and r6, then we tried building with
the ndk r4 from within the Android tree.

the functions in question are
   close() - hangs a process when the process is forked
   fprintf() - nothing gets written
   fopen() for write - the file does not get created as a new file

I have not tested beyond these functions.

Any insight would be greatly appreciated.

Thanks,
Adam

[android-developers] VpnServices.apk source and how does it work

2010-12-21 Thread Adam Bell
Hi all,

I have been searching for the source code for VpnServices.apk - trying
to understand just how this VPN application is implemented such that
root permissions are not required.
I think it is part of the core.jar but the only reference I can find
to it in the Android tree is core.mk

Could someone point me in the right direction and/or explain how the
app. gets at the IP packet stream to implement the security please.

I am very familiar with Linux kernel implementations and IPsec in
general.

Thanks,
Adam

[android-developers] Native VPN client

2010-10-21 Thread Adam Bell
Hi all,

Does anyone have any information of the source of the native VPN
client in Android 2.2 - what code base is it based on: openvpn,
sttrongswan, etc?

And specifically what feature set (IKEv2, mode-config, PKCS11,
smartcard usage, etc) and algorithms (ECDH, AES-256, Sha-256, etc) are
supported by it.

There is not a lot of info about it anywhere that I can find and these
details are not exposed in the configuration screens.

Thanks in adnvace
