2021-02-04ipsec: one thread index per-SANeale Ranns1-3/+3
Type: improvement AN SA is uni-drectional therefore it can be used only for encrypt or decrypt, not both. So it only needs one thread ID. free up some space on the 1st cacheline. Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: I21cb7cff70a763cbe2bffead860b574bc80b3136

2019-12-17ipsec: bind an SA to a workerNeale Ranns1-10/+28
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.

2019-07-24ipsec: GCM, Anti-replay and ESN fixessNeale Ranns1-2/+2
Type: fix Several Fixes: 1 - Anti-replay did not work with GCM becuase it overwrote the sequence number in the ESP header. To fix i added the seq num to the per-packet data so it is preserved 2 - The high sequence number was not byte swapped during ESP encrypt. 3 - openssl engine was the only one to return FAIL_DECRYPT for bad GCM the others return BAD_HMAC. removed the former 4 - improved tracing to show the low and high seq numbers 5 - documented the anti-replay window checks 6 - fixed scapy patch for ESN support for GCM 7 - tests for anti-reply (w/ and w/o ESN) for each crypto algo Change-Id: Id65d96b6d1d4dd821b2ab557e87468fff6d70e5b Signed-off-by: Neale Ranns <nranns@cisco.com>

2019-02-18IPSEC: move SA counters into the stats segmentNeale Ranns1-2/+8
1) stats are accessed via the stat segment which is more condusive to monitoring 2) stats are accurate in the presence of multiple threads. There's no guarantee that an SA is access from only one worker. Change-Id: Id5e217ea253ddfc9480aaedb0d008dea031b1148 Signed-off-by: Neale Ranns <nranns@cisco.com>
2019-02-07IPSEC: no second lookup after tunnel encapNeale Ranns1-3/+3
in the same maaner as with other tunnel tyeps we use the FIB to cache and track the destination used to reach the tunnel endpoint. Post encap we can then ship the packet straight to this adjacency and thus elide the costly second lookup. - SA add and del function so they can be used both directly from the API and for tunnels. - API change for the SA dump to use the SA type - ipsec_key_t type for convenience (copying, [un]formating) - no matching tunnel counters in ipsec-if-input Change-Id: I9d144a59667f7bf96442f4ca66bef5c1d3c7f1ea Signed-off-by: Neale Ranns <nranns@cisco.com>
