bpf: Support IPsec over IPv6 underlay#39620
Merged
Conversation
To support IPv6 underlays in IPsec, we need set_ipsec_encrypt to be able to take IPv6 tunnel endpoints as an argument. This information is passed via the ipcache value. A new helper function, lookup_node, then performs the IPv4 or IPv6 lookup in the node ID map. Signed-off-by: Paul Chaignon <paul.chaignon@gmail.com>
Support encrypted overlay for IPv6 underlays by detecting to-be-encrypted traffic and marking it for encryption, as is done in the IPv4 case. Signed-off-by: Paul Chaignon <paul.chaignon@gmail.com>

There was a problem hiding this comment.
Does our current e2e test setup already cover the IPsec over IPv6 underlay scenario?

No. As said in the PR description, that will come in a follow up PR with the agent changes. |
