2020-05-27ipsec: Add/Del IPSec SA is not MP safeNeale Ranns1-7/+0
Type: fix we can probably do better, but for now this is needed Signed-off-by: Neale Ranns <nranns@cisco.com> Change-Id: I07161f5ac07a70a0e6db6608ba31659d9bc2c9ed
2020-05-24ipsec: fixed chaining ops after add footer and icvPiotrX Kleski1-8/+11
In case there is no free space in first buffer for ICV and footer, additional buffer will be added, but esp_encrypt will stay in single buffer mode. The issue happens for the following payload sizes: - TCP packets with payload 1992 - ICMP packets with payload 2004 This fix moves the single/chained buffer ops selection to after esp_add_footer_and_icv call.

2020-05-04fib: midchain adjacency optimisationsNeale Ranns4-205/+120
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>

2020-03-31ipsec: fix udp-encap in transport modeAlexander Chernavin1-1/+7
Now UDP enacapsulation doesn't work in transport mode with crypto algorithms that have iv_sz=8 like AES GCM or 3DES CBC. That happens because the inserted UDP header overlaps with the old IP header and gets filled before the information from the old IP header can be copied to a new IP header. The result is a broken packet: 00:03:39:620863: esp4-encrypt-tun esp: sa-index 3 spi 3464048590 (0xce792fce) seq 31 sa-seq-hi 0 crypto aes-gcm-128 integrity none udp-encap-enabled 00:03:39:620867: adj-midchain-tx ... 00:03:39:620868: ip4-rewrite ... 00:03:39:620869: GigabitEthernet0/8/0-output GigabitEthernet0/8/0 IP4: 08:00:27:a9:6b:d6 -> 08:00:27:5a:dd:0c UDP: 10.255.0.10 -> 10.255.0.20 version 0, header length 0 tos 0x80, ttl 63, length 0, checksum 0x653e (should be 0xffff) dscp CS4 ecn NON_ECN fragment id 0x0000 UDP: 128 -> 0 length 0, checksum 0x0000 00:03:39:620870: GigabitEthernet0/8/0-tx GigabitEthernet0/8/0 tx queue 0 ...

2020-03-05api: ipsec: add missing IS_INBOUND flag.Christian Hopps2-0/+6
External IKE daemons need to be able to flag an SA as inbound (just as the included ike plugin does). This commit adds this flag to the API. This change is backward bug-compatible as not setting the flag (old clients) continues to mean all SAs are created as outbound and fib nodes are created for them. The addition of this flag inhibits this forwarding node creation as well as properly flagging the SA as inbound.

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.

2019-12-17ipsec: bind an SA to a workerNeale Ranns10-43/+642
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.
