Answer 1

The French Wikipedia page about iptables https://fr.wikipedia.org/wiki/Iptables states that the possibility to filter with --pid-owner or --cmd-owner was removed starting from kernel 2.6.14... and links to the kernel changelog where I couldn't check this assertion since I am not a specialist of what the kernel internal structures are for!

The equivalent page in English does not go into that level of detail.

Filtering with UID/GID still works.
