Details
NETLINK_FIREWALL is a family of Netlink-Sockets defined in include/uapi/linux/netlink.h (blame, raw).
It is an obsolete interface to transport IPv4 packets from netfilter to user space.
Excerpt from the netlink(7) man page:
NETLINK_FIREWALL (up to and including Linux 3.4)
Transport IPv4 packets from netfilter to user space. Used
by ip_queue.ko kernel module. After a long period of being
declared obsolete (in favor of the more advanced
nfnetlink_queue feature), NETLINK_FIREWALL was removed in
Linux 3.5.
See also the this answer on StackOverflow.
Usage example:
iptables -A OUTPUT -p UDP --dport 1234 -j NFQUEUE --queue-num 0

A ** in the Mod column marks info from Supportdata2 probes, which will always stay incomplete.
A - in the Mod column marks manual research, the Firmware then shows where the Object occurs, not the Relation.

Model-Matrix
Daily updated index of the presence, path and size of this netlink family for each model. Last update: 2024-11-21 05:21 GMT.
Showing all models using this netlink family. Click any column header (click-wait-click) to sort the list by the respective data.
The (main/scrpn/boot/arm/prx/atom/rtl) label in the Model column shows which CPU is meant for Multi-Linux models.
Note that this list comes from Supportdata2 probes, which can have arbitrary settings and come from different firmware versions.
It doesn't say much if a model is not listed here. It may be a missing supportdata2 file or just a disabled feature.

Help Supportdata2
The data in this article is incomplete since it was manually collected using the Supportdata2 project.
Unlike the Supportdata-Probes which have been collected for years Supportdata2 is brand new and only has a few probes.
If you have access to a shell then please help to extend the Supportdata2 collection to improve this data.
It's easy and it's done in minutes. Please send created data as an Email attachment to the address listed here. Thanks!
