2022-08-19ipsec: enable UDP encap for IPv6 ESP tun protectMatthew Smith7-49/+95
Type: improvement If an SA protecting an IPv6 tunnel interface has UDP encapsulation enabled, the code in esp_encrypt_inline() inserts a UDP header but does not set the next protocol or the UDP payload length, so the peer that receives the packet drops it. Set the next protocol field and the UDP payload length correctly. The port(s) for UDP encapsulation of IPsec was not registered for IPv6. Add this registration for IPv6 SAs when UDP encapsulation is enabled. Add punt handling for IPv6 IKE on NAT-T port. Add registration of linux-cp for the new punt reason.

2022-08-17fib: support "midchain delegate" removalAlexander Chernavin2-0/+31
Type: improvement Currently, once an adjacency is stacked on a FIB entry via adj_midchain_delegate_stack(), "midchain delegate" is created for the adjacency and the FIB index is stored there. And all further calls to adj_midchain_delegate_stack() even passing another FIB index will cause the function to still use the stored one. In other words, there is currently no way to stack an adjacency on another FIB index if "midchain delegate" already exists for it. Being able to stack on another FIB index is needed for the wireguard plugin. As per the protocol, peers can roam between different external endpoints. When an authenticated packet is received and it was sent from a different endpoint than currently stored, the endpoint needs to be updated and all futher communication needs to happen with that endpoint. Thus, the corresponding to that peer adjacencies need to be stacked on the FIB entry that corresponds to the new endpoint. With this change, add adj_midchain_delegate_remove() that removes "midchain delegate". When stacking on another FIB entry is needed, existing "midchain delegate" can be removed and then, a new one created with a new FIB index via adj_midchain_delegate_stack().

classify hash used to be stored as u64 in buffer metadata, use 32 bits instead: - on almost all our supported arch (x86 and arm64) we use crc32c intrinsics to compute the final hash: we really get a 32-bits hash - the hash itself is used to compute a 32-bits bucket index by masking upper bits: we always discard the higher 32-bits - this allows to increase the l2 classify buffer metadata padding such as it does not overlap with the ip fib_index metadata anymore. This overlap is an issue when using the 'set metadata' action in the ip ACL node which updates both fields Type: fix Change-Id: I5d35bdae97b96c3cae534e859b63950fb500ff50 Signed-off-by: Benoît Ganne <bganne@cisco.com>

2022-06-28ipsec: introduce spd fast path typesPiotr Bronowski1-0/+63
This patch introdcues basic types supporting fast path lookup. Fast path performs policy matching with use of hash lookup (particularly bihash tries has been used for that purpose). Fast path lookup addresses situation where huge number of policies is created (~100k or more). In such scenario adding/removing a policy and policy matching is not efficient and poorly scales (for example adding 500k policies takes a few hours. Also lookup time increases significantly). With fast path adding and matching up to 1M flows scales up linearly (adding 1M of policies takes about 150s on the test machine vs many hours in case of original implementation, also matching time is significantly improved). Fast path will not deal well with a huge number of policies that are spanning large ip/port ranges. Large range will be masked out almost entirely leaving only a few bits for calculating the hash key. Such keys will tend to gather much more policies than other keys and hash will match most of the packets anihilating advantages of hashing. Having said that we also think that it is not the real life scenario. Type: feature Signed-off-by: Piotr Bronowski <piotrx.bronowski@intel.com> Change-Id: I600dae5111a37768ed4b23aa18426e66bbf7b529
