Brendan Jackman 4aae6eb6af libbpf: Fix signed overflow in ringbuf_process_ring ... [ Upstream commit 2a30f9440640c418bcfbea9b2b344d268b58e0a2 ] One of our benchmarks running in (Google-internal) CI pushes data through the ringbuf faster htan than userspace is able to consume it. In this case it seems we're actually able to get >INT_MAX entries in a single ring_buffer__consume() call. ASAN detected that cnt overflows in this case. Fix by using 64-bit counter internally and then capping the result to INT_MAX before converting to the int return type. Do the same for the ring_buffer__poll().
