Subject: [xdp-hints] [PATCH bpf-next v3 00/21] XDP metadata via kfuncs for ice
Date: Wed, 19 Jul 2023 20:37:13 +0200 [thread overview]
Message-ID: <20230719183734.21681-1-larysa.zaremba@intel.com> (raw)
This series introduces XDP hints via kfuncs [0] to the ice driver.
Series brings the following existing hints to the ice driver:
- HW timestamp
- RX hash with type
Series also introduces new hints and adds their implementation
to ice and veth:
- VLAN tag with protocol
- Checksum status
The data above can now be accessed by XDP and userspace (AF_XDP) programs.
They can also be checked with xdp_metadata test and xdp_hw_metadata program.
[0] https://patchwork.kernel.org/project/netdevbpf/cover/20230119221536.3349901-1-sdf@google.com/
v2:
https://lore.kernel.org/bpf/20230703181226.19380-1-larysa.zaremba@intel.com/
v1:
https://lore.kernel.org/all/20230512152607.992209-1-larysa.zaremba@intel.com/
Changes since v2:
- redesign checksum hint, so now it gives full status
- rename vlan_tag -> vlan_tci, where applicable
- use open_netns() and close_netns() in xdp_metadata
- improve VLAN hint documentation
- replace CFI with DEI
- use VLAN_VID_MASK in xdp_metadata
- make vlan_get_tag() return -ENODATA
- remove unused rx_ptype in ice_xsk.c
- fix ice timestamp code division between patches
Changes since v1:
- directly return RX hash, RX timestamp and RX checksum status
in skb-common functions
- use intermediate enum value for checksum status in ice
- get rid of ring structure dependency in ice kfunc implementation
- make variables const, when possible, in ice implementation
- use -ENODATA instead of -EOPNOTSUPP for driver implementation
- instead of having 2 separate functions for c-tag and s-tag,
use 1 function that outputs both VLAN tag and protocol ID
- improve documentation for introduced hints
- update xdp_metadata selftest to test new hints
- implement new hints in veth, so they can be tested in xdp_metadata
- parse VLAN tag in xdp_hw_metadata
Aleksander Lobakin (1):
