From ceeb7eda94a3548958b30818495ef7eb12898727 Mon Sep 17 00:00:00 2001 From: Leon Hwang Date: Tue, 12 May 2026 23:31:54 +0800 Subject: bpf: Add syscall common attributes support for btf_load BPF_BTF_LOAD can now take log parameters from both union bpf_attr and struct bpf_common_attr, with the same merge rules as BPF_PROG_LOAD: - if both sides provide a complete log tuple (buf/size/level) and they match, use it; - if only one side provides log parameters, use that one; - if both sides provide complete tuples but they differ, return -EINVAL.
