2020-10-08ipsec: Allow SAs with NULL auth &crypto on IPSec interfaceNeale Ranns1-2/+3
Type: improvement on the dedicated IPSec interface, the SA describes the peer, so it is not possible to forward to a peer for which there is no SA. Therefore if an SA is added with NULL auth and integ then this explicitly states that this is what the peer desires. on the contrary on the IP-IP/GRE interface, in the absence of protection and an SA, then the traffic is sent in the clear. So adding NULL auth/crypto iSA is a means to describe that the peer should not be sent traffic. Signed-off-by: Neale Ranns <nranns@cisco.com> Change-Id: I7ad2d466cc74eb7ff8c4c84e0d7897d06e2fcf86

2020-05-04fib: midchain adjacency optimisationsNeale Ranns1-96/+92
Type: improvement - inline some common encap fixup functions into the midchain rewrite node so we don't incur the cost of the virtual function call - change the copy 'guess' from ethernet_header (which will never happen) to an ip4 header - add adj-midchain-tx to multiarch sources - don't run adj-midchain-tx as a feature, instead put this node as the adj's next and at the end of the feature arc. - cache the feature arc config index (to save the cache miss going to fetch it) - don't check if features are enabled when taking the arc (since we know they are) the last two changes will also benefit normal adjacencies taking the arc (i.e. for NAT, ACLs, etc) for IPSec: - don't run esp_encrypt as a feature, instead when required insert this node into the adj's next and into the end of the feature arc. this implies that encrypt is always 'the last feature' run, which is symmetric with decrypt always being the first. - esp_encrpyt for tunnels has adj-midchain-tx as next node Change-Id: Ida0af56a704302cf2d7797ded5f118a781e8acb7 Signed-off-by: Neale Ranns <nranns@cisco.com>

2020-04-14ipsec: validate number of input sasMatthew Smith1-0/+6
Type: fix There is a statically allocated array for inbound SAs which can hold 4 IDs. The input parameter containing the IDs of th inbound SAs is a vector and Its possible to pass a vector with more than 4 elements and write the memory past the end of the array. Fail if more than 4 SAs are passed in the vector. Change-Id: I0c9d321c902d6366b8aff816d04e343dcbd110eb Signed-off-by: Matthew Smith <mgsmith@netgate.com>
2020-02-25vlib: Punt reason allocation listener enable/disable callbackNeale Ranns1-23/+54
Type: improvement allow clients that allocate punt reasons to pass a callback function that is invoked when the first/last client registers to use/listen on that punt reason. This allows the client to perform some necessary configs that might not otherwise be enabled. IPSec uses this callback to register the ESP proto and UDP handling nodes, that would not otherwise be enabled unless a tunnel was present.
