What about clients? AFAICT from the output of:
sudo stap -e 'probe
process("/lib/x86_64-linux-gnu/libc.so.6").function("__gethostbyname_r"),
process("/lib/x86_64-linux-gnu/libc.so.6").function("gethostbyname"),
process("/lib/x86_64-linux-gnu/libc.so.6").function("gethostbyname2"),
process("/lib/x86_64-linux-gnu/libc.so.6").function("__gethostbyname2_r"),
process("/lib/x86_64-linux-gnu/libc.so.6").function("__new_gethostbyname2_r")
{ printf("[%s][%d]->%s(%s)\n", execname(), pid(), pp(), $name$)}'
All of google-chrome, firefox, thunderbird call at least one of
those with network supplied data.
Things like spam filters and antivirus are likely at risk
(thinking of network IDSes and other spam filtering/proxy appliances).
DHCP clients? Fancy wireless auth?
