Just after releasing Core Update 178 which was added into our release cycle to address Intel's and AMD's latest CPU vulnerabilities, we are back on track with our regular schedule. This release features Indirect Branch Tracking for user space, a completely rewritten ExtraHD amongst a large number of package updates and the usual bunch of bug fixes.

Indirect Branch Tracking for User Space

This technology uses a CPU extension which (if available) will check if a program returns from a function or jump correctly. If not, for example in case of injected code, an exception is being raised and the program is being terminated.

This is a follow-up after hardening our kernel against the same attack vector in Core Update 177 and had to be split off to keep updates an easier to handle smaller size.


This feature that allows mounting any extra storage into IPFire has been entirely rewritten. The code was hard to extend and some smaller issues became hard to fix which resulted in us making the decision for a rewrite. It should now be a lot more robust and easy to use.
