Subject: [PATCH bpf-next,v5 0/4] xfrm: interface: Add unstable helpers for XFRM metadata
Date: Sat, 3 Dec 2022 09:30:31 +0200 [thread overview]
Message-ID: <20221203073035.1798108-1-eyal.birger@gmail.com> (raw)
This patch series adds xfrm metadata helpers using the unstable kfunc
call interface for the TC-BPF hooks.
This allows steering traffic towards different IPsec connections based
on logic implemented in bpf programs.
The helpers are integrated into the xfrm_interface module. For this
purpose the main functionality of this module is moved to
xfrm_interface_core.c.
---
changes in v5:
- avoid cleanup of percpu dsts as detailed in patch 2
changes in v3:
- tag bpf-next tree instead of ipsec-next
- add IFLA_XFRM_COLLECT_METADATA sync patch
Eyal Birger (4):
xfrm: interface: rename xfrm_interface.c to xfrm_interface_core.c
xfrm: interface: Add unstable helpers for setting/getting XFRM
metadata from TC-BPF
tools: add IFLA_XFRM_COLLECT_METADATA to uapi/linux/if_link.h
selftests/bpf: add xfrm_info tests
