IPFire 2.19 – Core Update 120 is available for testing and we are excited that it is packet with a large number of features! They will increase security of the entire system, increase performance of some cryptographic operations as well as fixing a number of smaller bugs.
Thanks for the people who contributed to this Core Update by submitting their patches and please help us to support everyone’s work with your donation!
In some installations it might be desirable to only let the proxy cache objects in memory and not on disk. Especially when Internet connectivity is fast and storage is slow this is most useful.
The web UI now allows to set the disk cache size to zero which will disable the disk cache entirely. Thanks to Daniel for working on this.
IPFire has migrated to OpenVPN 2.4 which introduces new ciphers of the AES-GCM class which will increase throughput on systems that have hardware acceleration for it. The update also brings various other smaller improvements.
Erik has been working on integration this which has required some work under the hood but is compatible with any previous configurations for both roadwarrior connections and net-to-net connections.
Cryptography is one of the foundations to a secure system. We have updated the distribution to use the latest version of the OpenSSL cryptography library (version 1.1.0). This comes with a number of new ciphers and major refacturing of the code base has been conducted.
With this change, we have decided to entirely deprecate SSLv3 and the web user interface will require TLSv1.2 which is also the default for many other services. We have configured a hardened list of ciphers which only uses recent algorithms and entirely removes broken or weak algorithms like RC4, MD5 and so on.
Please check before this update if you are relying on any of those, and upgrade your dependent systems.
Various packages in IPFire had to be patched to be able to use the new library. This major work was necessary to provide IPFire with the latest cryptography, migrate away from deprecated algorithms and take advantage of new technology. For example the ChaCha20-Poly1305 ciphersuite is available which performs faster on mobile devices.
The old version of the OpenSSL library (1.0.2) is still left in the system for compatibility reasons and will continue to be maintained by us for a short while. Eventually, this will be removed entirely, so please migrate any custom-built add-ons away from using OpenSSL 1.0.2.
These add-ons have been updated:
asterisk’s documentation is now included in the package which has been missing earlier and rendered asterisk unable to start
