2020-01-04ipsec: Targeted unit testingNeale Ranns1-4/+8
Type: fix 1 - big packets; chained buffers and those without enoguh space to add ESP header 2 - IPv6 extension headers in packets that are encrypted/decrypted 3 - Interface protection with SAs that have null algorithms Signed-off-by: Neale Ranns <nranns@cisco.com> Change-Id: Ie330861fb06a9b248d9dcd5c730e21326ac8e973
2019-12-17ipsec: bind an SA to a workerNeale Ranns1-4/+23
the sequence number increment and the anti-replay window checks must be atomic. Given the vector nature of VPP we can't simply use atomic increments for sequence numbers, since a vector on thread 1 with lower sequence numbers could be 'overtaken' by packets on thread 2 with higher sequence numbers. The anti-replay logic requires a critical section, not just atomics, and we don't want that. So when the SA see the first packet it is bound to that worker all subsequent packets, that arrive on a different worker, are subject to a handoff.

2019-09-30ipsec: add insecure option for format of SAChristian E. Hopps1-0/+1
If specified, shows keys, otherwise redacts. This change sets this flag in the existing CLI code (thus maintaining the old behavior). The use case for not specifying the insecure flag (and thus redacting the keys from the show output) is for log messages. Type: feature Signed-off-by: Christian E.

2019-07-12ipsec: drop outbound ESP when no crypto alg setMatthew Smith1-0/+7
Type: fix If a tunnel interface has the crypto alg set on the outbound SA to IPSEC_CRYPTO_ALG_NONE and packets are sent out that interface, the attempt to write an ESP trailer on the packet occurs at the wrong offset and the vnet buffer opaque data is corrupted, which can result in a SEGV when a subsequent node attempts to use that data. When an outbound SA is set on a tunnel interface which has no crypto alg set, add a node to the ip{4,6}-output feature arcs which drops all packets leaving that interface instead of adding the node which would try to encrypt the packets.

Polling the stats segment is much more efficient (if the SA lifetime is based on packet/bytes) - emit the policy index in the packet trace and CLI commands.

2018-12-11Add IPSec interface FIB index for TX packetPierre Pfister1-0/+2
This patch adds a configuration parameter to IPSec tunnels, enabling custom FIB selection for encapsulated packets. Although this option could also be used for policy-based IPSec, this change only enables it for virtual-tunnel-interface mode. Note that this patch does change the API default behavior regarding TX fib selection for encapsulated packets. Previous behavior was to use the same FIB after and before encap. The new default behavior consists in using the FIB 0 as default. Change-Id: I5c212af909940a8cf6c7e3971bdc7623a2296452 Signed-off-by: Pierre Pfister <ppfister@cisco.com>

2018-04-19Allow an IPsec tunnel interface to be renumberedMatthew Smith1-0/+4
When creating an IPsec tunnel interface, allow a numeric identifier to be set for use in the interface's name in place of the dev instance. Default to using the dev instance if no value is explicitly set. When an IPsec tunnel is deleted, the interface is deleted now instead of being kept in a pool of available hw interfaces. Otherwise there was the possibility of conflicting tx node names between deleted tunnels and newly created ones.

Make it easier to integrate with external IKE daemon. IPsec interfaces can have one or both SAs replaced after creation.

The DPDK cryptodev cli commands are replaced by the following new commands: - show dpdk crypto devices - show dpdk crypto placement [verbose] - set dpdk crypto placement (<device> <thread> | auto) - clear dpdk crypto placement <device> [<thread>] - show dpdk crypto pools Change-Id: I47324517ede82d3e6e0e9f9c71c1a3433714b27b Signed-off-by: Sergio Gonzalez Monroy <sergio.gonzalez.monroy@intel.com>

This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.
