From 7283137a7622292076dd8b7f3b8b2bb203ce5a14 Mon Sep 17 00:00:00 2001 From: Hengqi Chen Date: Sun, 26 Mar 2023 09:53:41 +0000 Subject: [PATCH] selftests/bpf: Don't assume page size is 4096 The verifier test creates BPF ringbuf maps using hard-coded 4096 as max_entries. Some tests will fail if the page size of the running kernel is not 4096. Use getpagesize() instead.
