The X.Org/X11 Server has been hit by many security vulnerabilities over the past decade as security researchers eye more open-source software. Some of these vulnerabilities date back to even the 80's and 90's given how X11 has built up over time. The X.Org Server security was previously characterized as being even worse than it looks while today the latest vulnerabilities have been made public...

Building off the work sent out by Google engineers in recent months and merged for Linux 5.8 around RAPL support for AMD Zen / Zen 2 CPUs with supporting the "runtime average power limiting" counters on Linux similar to Intel's longstanding support, that work has continued now with Zen RAPL support in the PowerCap driver...

For those using the Intel ICE Linux network driver that is used for the likes of the E800 series, it's now going to be easier updating the device firmware from Linux...

Worked out in recent months by an Amazon engineer was optional L1 data cache flushing on context switches to allow for greater computer security in an era of data sampling vulnerabilities and other data leakage issues via side channels. It was sent in for Linux 5.8 but Linus Torvalds characterized it as "beyond stupid" and not being convinced by it. Well, now it's been revised but isn't yet clear if it will appease Torvalds for mainline inclusion...

As outlined a few months ago, Intel's future Sapphire Rapids and Alder Lake processors are set to add a SERIALIZE instruction. That SERIALIZE instruction ensures all flags/register/memory modifications are complete as well as draining all buffered writes to memory before the next instruction is executed. Linux is moving forward with preparing to make use of this new CPU instruction in its function for stopping speculative execution and prefetching of modified code...
