From 9b42c1f179a614e11893ae4619f0304a38f481ae Mon Sep 17 00:00:00 2001 From: Steffen Klassert Date: Tue, 12 Jun 2018 12:44:26 +0200 Subject: xfrm: Extend the output_mark to support input direction and masking. We already support setting an output mark at the xfrm_state, unfortunately this does not support the input direction and masking the marks that will be applied to the skb. This change adds support applying a masked value in both directions. The existing XFRMA_OUTPUT_MARK number is reused for this purpose and as it is now bi-directional, it is renamed to XFRMA_SET_MARK. An additional XFRMA_SET_MARK_MASK attribute is added for setting the mask. If the attribute mask not provided, it is set to 0xffffffff, keeping the XFRMA_OUTPUT_MARK existing 'full mask' semantics.
