[linux-audio-dev] hearnet improvement

[Dmitry Baikov]

Hi!
First of all, thanks for a great program!

I made two patches for it:
1) make hearnet suid and drop privileges right after libpcap initialization.
 I had to move libpcap init code above jack

So, you can use hearnet as regular user.

2) Mutex in jack_process is a very bad thing. Moreover, it seems
there's no need for it, as voice->active field serves as a mutex.
Attached patch removes pthread_mutex.
If you think voice->active assumption is a weak one, the problem can
be solved with a pair of jack_ringbuffers: one for free voices and one
for active.


Regards,

Dmitry.
