Hi Gianni,

I could reproduce this issue and also found your post on StackExchange:
http://unix.stackexchange.com/questions/308622/cap-net-raw-influences-pt...

Apparently this patch is responsible for the regression:
https://github.com/orocos-toolchain/rtt/pull/128 in combination with
https://github.com/orocos-toolchain/rtt/commit/bc05dceed2f123c35893bf003...

I also cannot explain why the capability set influences pthread_setname_np,
but I will create a hotfix for 2.8.3 and rerelease it into ROS. A failure
the set the name of the thread should not lead to the termination of the
process.

Cheers,
Johannes
