From 3bc253c2e652cf5f12cd8c00d80d8ec55d67d1a7 Mon Sep 17 00:00:00 2001 From: Geliang Tang Date: Thu, 19 May 2022 16:30:10 -0700 Subject: bpf: Add bpf_skc_to_mptcp_sock_proto This patch implements a new struct bpf_func_proto, named bpf_skc_to_mptcp_sock_proto. Define a new bpf_id BTF_SOCK_TYPE_MPTCP, and a new helper bpf_skc_to_mptcp_sock(), which invokes another new helper bpf_mptcp_sock_from_subflow() in net/mptcp/bpf.c to get struct mptcp_sock from a given subflow socket. v2: Emit BTF type, add func_id checks in verifier.c and bpf_trace.c, remove build check for CONFIG_BPF_JIT v5: Drop EXPORT_SYMBOL (Martin) Co-developed-by: Nicolas Rybowski Co-developed-by: Matthieu Baerts Signed-off-by: Nicolas Rybowski Signed-off-by: Matthieu Baerts Signed-off-by: Geliang Tang Signed-off-by: Mat Martineau Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20220519233016.105670-2-mathew.j.martineau@linux.intel.com --- scripts/bpf_doc.py | 2 ++ 1 file changed, 2 insertions(+) (limited to 'scripts/bpf_doc.py') diff --git a/scripts/bpf_doc.py b/scripts/bpf_doc.py index 096625242475..d5452f7eb996 100755 --- a/scripts/bpf_doc.py +++ b/scripts/bpf_doc.py @@ -633,6 +633,7 @@ class PrinterHelpers(Printer): 'struct socket', 'struct file', 'struct bpf_timer', + 'struct mptcp_sock', ] known_types = { '...', @@ -682,6 +683,7 @@ class PrinterHelpers(Printer): 'struct socket', 'struct file', 'struct bpf_timer', + 'struct mptcp_sock', } mapped_types = { 'u8': '__u8', -- cgit v1.2.3
