Summary

bpf: Disable preemption in bpf_get_stackid

Details

In the Linux kernel, the following vulnerability has been resolved:

bpf: Disable preemption in bpf_get_stackid

The get_perf_callchain call needs disabled preemption plus we need it disabled as long as we access its returned trace entries buffer.

Note the bpf_get_stackid_pe function is executed already with preemption disabled.
