From 7c81c2490c73e614c6d48e4f339f4f224140b565 Mon Sep 17 00:00:00 2001 From: Kui-Feng Lee Date: Fri, 19 Jan 2024 14:50:04 -0800 Subject: bpf: export btf_ctx_access to modules. The module requires the use of btf_ctx_access() to invoke bpf_tracing_btf_ctx_access() from a module. This function is valuable for implementing validation functions that ensure proper access to ctx.
