Samba and GnuTLS
More or less since the beginning of Samba, it implemented the cryptography it needed to talk to Windows on its own. One reason is that Windows didn’t follow the standards or used ciphers nobody else really used. This is changing right now!
GnuTLS already was a used by Samba if available and it is a requirement if you build the Samba AD with MIT Kerberos already. So to get out of the crypto business we decided to use GnuTLS as our crypto library.
With Samba 4.11 we did the first step using GnuTLS and required GnuTLS 3.2. With Samba 4.12 the requirement will be at least GnuTLS 3.4.7. The reason is that we require AEAD for AES-CCM and AES-GCM and 3.4.7 is already the requirement if building Samba AD with MIT Kerberos. This allowed us also to delete a lot of code!

Samba 4.12 Bringing Much Faster Encryption Performance With GnuTLS
Samba 4.11 was just released a few weeks back with big scalability improvements, but looking ahead to Samba 4.12 will be some big performance improvements for those leveraging encryption.
Samba 4.12 for SMB3 file transfers with encryption will be an order of 4~6 times faster than current performance levels! This is coming as Samba is beginning to properly leverage GnuTLS rather than historically implementing its own crypto methods.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
