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/test/bpf_cgroup | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'sys/linux/test') diff --git a/sys/linux/test/bpf_cgroup b/sys/linux/test/bpf_cgroup index 4ff19075d..8d341eb99 100644 --- a/sys/linux/test/bpf_cgroup +++ b/sys/linux/test/bpf_cgroup @@ -6,7 +6,7 @@ r1 = write$tcp_congestion(r0, &AUTO='reno\x00', AUTO) # Now, load a BPF_PROG_TYPE_CGROUP_SYSCTL that simply returns 0, which will block all writes to /proc/sys -r2 = bpf$PROG_LOAD(AUTO, &AUTO={0x17, AUTO, &AUTO=@framed={{AUTO, AUTO, AUTO, AUTO, 0x0, AUTO, AUTO, AUTO, 0x0}, [], {AUTO, AUTO, AUTO, AUTO}}, &AUTO='GPL\x00', 0x0, 0x0, 0x0, 0x0, 0x0, "00000000000000000000000000000000", 0x0, 0x12, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}, 0x9c) +r2 = bpf$PROG_LOAD(AUTO, &AUTO={0x17, AUTO, &AUTO=@framed={{AUTO, AUTO, AUTO, AUTO, 0x0, AUTO, AUTO, AUTO, 0x0}, [], {AUTO, AUTO, AUTO, AUTO}}, &AUTO='GPL\x00', 0x0, 0x0, 0x0, 0x0, 0x0, "00000000000000000000000000000000", 0x0, 0x12, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0}, 0xa0) r3 = openat(0xffffffffffffff9c, &AUTO='./cgroup\x00', 0x0, 0x0) -- cgit mrf-deployment
