XDP closer integration with network stack

"We claim XDP is not kernel-bypass, as it is a layer before and it can easily fall-through to netstack. Reality is that it can easily be (ab)used to create a kernel-bypass situation, where non of the kernel facilities are used (in form of BPF-helpers and in-kernel tables)."

Undercover reporter reveals life in a Polish troll farm

“I burst out laughing!” writes Girl from Żoliborz, a self-described “traditionalist” commenting on a newspaper story about a former campaign adviser to Barack Obama and Emmanuel Macron coming to Warsaw to address a group of liberal activists. “The opposition has nothing to offer. That’s why they use nonsense to pull the wool over people’s eyes,” replies Magda Rostocka, whose profile tells her almost 4,400 followers she is “left-handed with her heart on the right”. **In reality, neither woman existed.** Both accounts were run by the paid employees of a small marketing company based in the city of Wrocław in southwest Poland."

The troll farm employs disabled people and has received around £300,000 from Poland’s National Disabled Rehabilitation Fund.
