From b64118ab2f7c483d4d00a7d022230a96d88c8af6 Mon Sep 17 00:00:00 2001 From: Paul Chaignon Date: Sat, 6 May 2023 15:41:32 +0200 Subject: sys/linux: support log_true_size field in bpf(2) PROG_LOAD Commit [1] upstream added a new field to the bpf(2) PROG_LOAD command for the kernel to return the buffer size that would be required to store all logs. This is an output-only field so probably not much point in fuzzing it, so let's fix it to 0. 1 - https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=47a71c1f9af0 Signed-off-by: Paul Chaignon --- sys/linux/bpf.txt | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'sys/linux/bpf.txt') diff --git a/sys/linux/bpf.txt b/sys/linux/bpf.txt index c321b38c8..9455ba652 100644 --- a/sys/linux/bpf.txt +++ b/sys/linux/bpf.txt @@ -226,6 +226,7 @@ type bpf_prog_t[TYPE, ATTACH_TYPE, BTF_ID, PROG_FD] { fd_array ptr64[in, array[fd_bpf_map], opt] core_relos ptr64[in, array[bpf_core_relo], opt] core_relo_rec_size const[BPF_CORE_RELO_SIZE, int32] + log_true_size int32 } type bpf_prog bpf_prog_t[flags[bpf_prog_type, int32], flags[bpf_attach_type, int32], bpf_btf_id[opt], fd_bpf_prog[opt]] @@ -554,7 +555,7 @@ bpf_test_prog_arg { inctx ptr64[in, array[int8]] outctx ptr64[in, array[int8]] flags flags[bpf_prog_test_run_flags, int32] - cpu int32 + cpu const[0, int32] } bpf_prog_get_next_id_arg { -- cgit mrf-deployment
