Subject: [PATCH iproute2 V5 0/3] tc: Support for ip tunnel metadata set/unset/classify
Hi,
This short series adds support for matching and setting metadata for ip tunnel
shared device using the TC system, introduced in kernel 4.9 [1].
Applied and tested on top of commit b6c7fc61faab ("ss: print new tcp_info
fields: busy, rwnd-limited, sndbuf-limited times")
Example usage:
$ tc filter add dev vxlan0 protocol ip parent ffff: \
flower \
enc_src_ip 11.11.0.2 \
enc_dst_ip 11.11.0.1 \
enc_key_id 11 \
dst_ip 11.11.11.1 \
action mirred egress redirect dev vnet0
$ tc filter add dev net0 protocol ip parent ffff: \
flower \
ip_proto 1 \
dst_ip 11.11.11.2 \
action tunnel_key set \
src_ip 11.11.0.1 \
dst_ip 11.11.0.2 \
id 11 \
action mirred egress redirect dev vxlan0
[1] - d1ba24feb466 ("Merge branch 'act_tunnel_key'")
Thanks,
Amir
Changes from V4:
- Fix rebase conflicts for net-next
Changes from V3:
- Fix bad wording in the man page about the use of the 'unset' operation
Changes from V2:
- Use const where needed
- Don't lose return value
- Introduce rta_getattr_be16() and rta_getattr_be32()
Changes from V1:
- Updated Patch 2/2 ("tc/act_tunnel: Introduce ip tunnel action") commit log
and the man page tc-tunnel_key to reflect the fact that 'unset' operation is
no mandatory.
And describe when it might be needed.
- Rename the 'release' operation to 'unset'
