2019-07-31ipsec: Typo in flag nameNeale Ranns1-1/+1
Type: fix Change-Id: I0c9353598d3c9b7ea587ea8a2b6e1faa5454843d Signed-off-by: Neale Ranns <nranns@cisco.com>
2019-07-24ipsec: GCM, Anti-replay and ESN fixessNeale Ranns1-26/+103
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>
2019-07-12ipsec: Reference count the SAsNeale Ranns1-18/+16
- this remove the need to iterate through all state when deleting an SA - and ensures that if the SA is deleted by the client is remains for use in any state until that state is also removed.

2019-06-17ipsec: One DPO per SANeale Ranns1-4/+1
An SA can be used only for ESP or AH nver both, so it needs only one coresponding DPO. Type: refactor Change-Id: I689060f795ee352245a0eaed0890a6b234c63d71 Signed-off-by: Neale Ranns <nranns@cisco.com>
2019-06-07ipsec: remove the set_key APINeale Ranns1-2/+0
there's no use case to just change the key of an SA. instead the SA should be renegociated and the new SA applied to the existing SPD entry or tunnel. the set_key functions were untested.

2019-04-26crypto, ipsec: change GCM IV handlingDamjan Marion1-0/+1
- nonce construction out of salt and iv is ipsec specific so it should be handled in ipsec code - fixes GCM unit tests - GCM IV is constructed out of simple counter, per RFC4106 section 3.1 Change-Id: Ib7712cc9612830daa737f5171d8384f1d361bb61 Signed-off-by: Damjan Marion <damarion@cisco.com>

2019-02-18IPSEC: move SA counters into the stats segmentNeale Ranns1-3/+7
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 Ranns1-7/+61
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>
