Linux 5.13 To Address Some Networking Overhead Caused By Retpolines

It's been three years that Retpolines (return trampolines) have been around as part of the Spectre defenses on Linux and kernel developers in particular are still working to better optimize different areas of their code to deal with the performance overhead incurred.

The Linux Kernel Looks To Eventually Drop Support For WiMAX

With the WiMAX 802.16 standard not being widely used outside of the Aeronautical Mobile Airport Communication System (AeroMACS) and usage in some developing nations, the Linux kernel may end up dropping its support for WiMAX but first there is a proposal to demote it to staging while seeing if any users remain.

Facebook Still Pursuing "NetGPU" - Working On AMD GPU Support In Addition To NVIDIA

It was the recent Facebook patches for implementing NetGPU that with one of the NVIDIA-focused patches led to the recent controversy around "GPL condoms" in the kernel and ultimately leading to new protections with Linux 5.9. That NetGPU code is still being worked on by Facebook with upstream hopes but now in addition to the NVIDIA driver support they are also working on AMD GPU support with the open-source driver.

There Is Now A WireGuard Benchmark For Testing Linux Networking Performance

With WireGuard added to the Linux 5.6 kernel and it being back-ported to Ubuntu 20.04 LTS and its tools getting packaged up by more Linux distributions, it's finally the year of WireGuard. With its usage set to skyrocket as supported kernels and the WireGuard utilities become available out-of-the-box on more distributions, there is now a WireGuard benchmark for stressing the kernel and its support.
