From d2f7cd20a7c7742b83d2c899044d4f2a851a4a7d Mon Sep 17 00:00:00 2001 From: Yonghong Song Date: Mon, 12 Jan 2026 22:10:28 -0800 Subject: [PATCH] selftests/bpf: Fix sk_bypass_prot_mem failure with 64K page The current selftest sk_bypass_prot_mem only supports 4K page. When running with 64K page on arm64, the following failure happens: ... check_bypass:FAIL:no bypass unexpected no bypass: actual 3 <= expected 32 ... #385/1 sk_bypass_prot_mem/TCP :FAIL ... check_bypass:FAIL:no bypass unexpected no bypass: actual 4 <= expected 32 ... #385/2 sk_bypass_prot_mem/UDP :FAIL ... Adding support to 64K page as well fixed the failure.
