Linux Kernel Patches Posted For USB Support With Realtek RTW88 WiFi Driver
Linux Kernel Patches Posted For USB Support With Realtek RTW88 WiFi Driver

Back in 2019 Realtek contributed the open-source "RTW88" WiFi driver to the Linux kernel for supporting their newer wireless chipsets on Linux. To date the mainline driver has just supported their PCI-based WiFi adapters while a patch series now out for review extends the driver to supporting their newer USB-specific chipsets.

AMD/Xilinx Solarflare Network Driver Restructuring Queued For Linux 5.19
AMD/Xilinx Solarflare Network Driver Restructuring Queued For Linux 5.19

The Solarflare "SFC" network driver within the Linux kernel for their high performance network adapters, owned by Xilinx and now owned by AMD, is seeing some restructuring with the next version of the Linux kernel. The intention is on shifting older network hardware to a separate kernel module/driver so improvements and new hardware support can be the focus with this main Solarflare Linux network driver.

Silicon Labs WiFi Linux Driver To Be Promoted Out Of Staging
Silicon Labs WiFi Linux Driver To Be Promoted Out Of Staging

Added back in 2019 to the Linux staging area was the "WFX" WiFi driver for low-power IoT hardware from Silicon Labs. After three years of hard work by Silicon Labs engineers and open-source developers, this driver for the WF200 series of wireless chips is set to be promoted in the Linux 5.19 cycle.

The Networking Changes For Linux 5.17 Are Very Exciting
The Networking Changes For Linux 5.17 Are Very Exciting

The Linux networking subsystem updates for the in-development 5.17 kernel are quite exciting as usual given how prolific Linux is from large servers in the cloud to running on enterprise networking gear down to Linux on small IoT hardware. Not only is there a lot of hardware driver action as usual but also some key performance/latency optimizations.

Linux Patches Posted For Enabling WiFi On Apple M1/T2 Platforms
Linux Patches Posted For Enabling WiFi On Apple M1/T2 Platforms

Another important step toward Apple M1 hardware being useful under Linux is in the process of being realized... Working WiFi. The initial "request for comments" patch series was sent out today enabling the Broadcom "BRCMFMAC" driver to work for the wireless LAN support on the M1 SoC as well as with the Apple T2 platforms.

Another Sizable Performance Optimization To Benefit Network Code With Linux 5.17
Another Sizable Performance Optimization To Benefit Network Code With Linux 5.17

Last week I wrote about a big TCP performance optimization having been queued up into net-next for Linux 5.17. That optimization can yield significant TCP throughput improvements especially with today's high-end 100Gb+ network hardware. There is now another separate juicy optimization to benefit the Linux network performance in the next kernel cycle.

Linux 5.17 To Boast A Big TCP Performance Optimization
Linux 5.17 To Boast A Big TCP Performance Optimization

While the Linux 5.16 merge window just ended and that kernel won't be out until the tail end of the calendar year, already for Linux 5.17 new material is beginning to accumulate in the respective subsystem development trees... One set of changes merged this morning from Google can provide a sizable performance win around TCP performance in the datacenter.

BPF-Based Linux Firewall "bpfilter" Shows Impressive Performance Potential
BPF-Based Linux Firewall "bpfilter" Shows Impressive Performance Potential

Generating much excitement back in 2018 was bpfilter for the potential to better Linux's firewall and packet filtering by making it more robust and performance. Recently work on this BPF-based firewall solution was renewed and the performance potential over iptables and nftables is looking very good for the future.

Samsung Revs Its In-Kernel SMB3 Server Focused On Fast Performance, New Features

While Samba is well known for SMB/CIFS server support on Linux and other platforms for supporting Microsoft's SMB networking protocol for file and print services, Samba is implemented in user-space while Samsung has been pursuing an SMB server implemented in kernel-space for better performance and wiring up new features that can be more easily accomplished within the kernel.

WireGuard Sees Native, High-Performance Port To The Windows Kernel

The excellent WireGuard open-source secure VPN tunnel has been seeing growing adoption on Linux now that it's been in the mainline kernel for a while and also seeing continued progress on the BSDs. While there has been beta WireGuard for Windows in user-space, "WireGuardNT" was announced today as a native high-performance port to the Windows kernel.
