I'm curios to know how bpf_probe_read is able to read user-mode memory in the face of page faulting.
I know in the helper it disables page faulting, but what does that mean? If the memory the probe is trying to read is paged out then how does my probe work? It seems bpf_probe_read is best effort then. Is that true? -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.
