kernel: bpf, cpumap: Make sure kthread is running before map update returns

A race condition was found in the Linux kernel's BPF cpumap implementation in the kthread lifecycle management. A local user can trigger this issue by running XDP redirect operations when the per-CPU kthread is stopped prematurely before processing queued frames, causing the cleanup code to find ...
