I need 4 tweets for the highlights in main #network merge for #Linux 5.10:

* #BPF programs can be shipped with the #kernel and loaded on boot via the User Mode Driver mechan. git.kernel.org/torvalds/c/0bc…

* sleepable BPF programs
git.kernel.org/torvalds/c/104…
lwn.net/Articles/82541…

(1/4)

* BPF Type Format (BTF) support for type and enum discovery & support for using BTF within the kernel itself
git.kernel.org/torvalds/c/98b…

* add and consume TCP header options in BPF programs, allowing easy experim. and deployment-specific TCP option use
git.kernel.org/torvalds/c/0bc…

(2/4)

* redirect_neigh() BPF packet redirect helper, allowing to limit stack traversal in common container configs; Daniel reports ~10Gbps => ~15Gbps performance gain
git.kernel.org/torvalds/c/b4a…

* BPF programs can call map_update_elem on sockmaps
git.kernel.org/torvalds/c/3c4…

(3/4)

* Add XDP support for Intel's igb driver
git.kernel.org/torvalds/c/9cb…

* Add support for various auth offloads in WiFi APs, e.g. SAE (WPA3) offload.
