If we add the EDNS client subnet option, or the client's MAC address, then the reply we get back may very depending on that. Since the cache is ignorant of such things, it's not safe to cache such replies. This patch determines when a dangerous EDNS option is being added and disables caching. Note that for much the same reason, we can't combine multiple queries for the same question when dangerous EDNS options are being added, and the code now handles that in the same way. This query combining is required for security against cache poisoning, so disabling the cache has a security function as well as a correctness one. Signed-off-by: DL6ER <dl6er@dl6er.de>
Network-wide ad blocking via your own Linux hardware
FTLDNS™ (pihole-FTL) provides an interactive API and also generates statistics for Pi-hole®'s Web interface.
- Fast: stats are read directly from memory by coupling our codebase closely with
dnsmasq - Versatile: upstream changes to
dnsmasqcan quickly be merged in without much conflict - Lightweight: runs smoothly with minimal hardware and software requirements such as Raspberry Pi Zero
- Interactive: our API can be used to interface with your projects
- Insightful: stats normally reserved inside of
dnsmasqare made available so you can see what's really happening on your network
Official documentation
The official FTLDNS documentation can be found here.
Installation
FTLDNS (pihole-FTL) is installed by default when you choose to enable the Web interface when installing Pi-hole.
IMPORTANT!
FTLDNS will disable any existing installations of
dnsmasq. This is because FTLDNS isdnsmasq+ Pi-hole's code, so both cannot run simultaneously.
