2022-01-17ipsec: IPSec interface correct drop w/ no protectionNeale Ranns1-0/+16
Type: improvement When an IPSec interface is first constructed, the end node of the feature arc is not changed, which means it is interface-output. This means that traffic directed into adjacencies on the link, that do not have protection (w/ an SA), drop like this: ... 00:00:01:111710: ip4-midchain tx_sw_if_index 4 dpo-idx 24 : ipv4 via 0.0.0.0 ipsec0: mtu:9000 next:6 flags:[] stacked-on: [@1]: dpo-drop ip4 flow hash: 0x00000000 00000000: 4500005c000100003f01cb8cac100202010101010800ecf40000000058585858 00000020: 58585858585858585858585858585858585858585858585858585858 00:00:01:111829: local0-output ipsec0 00000000: 4500005c000100003f01cb8cac100202010101010800ecf40000000058585858 00000020: 5858585858585858585858585858585858585858585858585858585858585858 00000040: 58585858585858585858585858585858585858585858585858585858c2cf08c0 00000060: 2a2c103cd0126bd8b03c4ec20ce2bd02dd77b3e3a4f49664 00:00:01:112017: error-drop rx:pg1 00:00:01:112034: drop local0-output: interface is down although that's a drop, no packets should go to local0, and we want all IPvX packets to go through ipX-drop. This change sets the interface's end-arc node to the appropriate drop node when the interface is created, and when the last protection is removed. The resulting drop is: ... 00:00:01:111504: ip4-midchain tx_sw_if_index 4 dpo-idx 24 : ipv4 via 0.0.0.0 ipsec0: mtu:9000 next:0 flags:[] stacked-on: [@1]: dpo-drop ip4 flow hash: 0x00000000 00000000: 4500005c000100003f01cb8cac100202010101010800ecf40000000058585858 00000020: 58585858585858585858585858585858585858585858585858585858 00:00:01:111533: ip4-drop ICMP: 172.16.2.2 -> 1.1.1.1 tos 0x00, ttl 63, length 92, checksum 0xcb8c dscp CS0 ecn NON_ECN fragment id 0x0001 ICMP echo_request checksum 0xecf4 id 0 00:00:01:111620: error-drop rx:pg1 00:00:01:111640: drop null-node: blackholed packets Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: I7e7de23c541d9f1210a05e6984a688f1f821a155
2021-11-19fib: Don't use [midchain] adjacencies to change an interface's feature arcNeale Ranns1-0/+8
Type: fix Using the adjacency to modify the interface's feature arc doesn't work, since there are potentially more than one adj per-interface. Instead have the interface, when it is created, register what the end node of the feature arc is. This end node is then also used as the interface's tx node (i.e. it is used as the adjacency's next-node). rename adj-midhcain-tx as 'tunnel-output', that's a bit more intuitive. There's also a fix in config string handling to: 1- prevent false sharing of strings when the end node of the arc is different. 2- call registered listeners when the end node is changed For IPSec the consequences are that one cannot provide per-adjacency behaviour using different end-nodes - this was previously done for the no-SA and an SA with no protection. These cases are no handled in the esp-encrypt node. Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: If3a83d03a3000f28820d9a9cb4101d244803d084

2021-02-09Revert "ipsec: Use the new tunnel API types to add flow label and TTL copy"Matthew Smith1-3/+12
This reverts commit c7eaa711f3e25580687df0618e9ca80d3dc85e5f. Reason for revert: The jenkins job named 'vpp-merge-master-ubuntu1804-x86_64' had 2 IPv6 AH tests fail after the change was merged. Those 2 tests also failed the next time that job ran after an unrelated change was merged. Change-Id: I0e2c3ee895114029066c82624e79807af575b6c0 Signed-off-by: Matthew Smith <mgsmith@netgate.com>

2020-10-16ipsec: fix instance, and cli del for new ipsec interfaceEric Kinzie1-3/+1
- use user instance number in interface name Restore the behavior of previous versions where the IPsec tunnel interface name contained the value of the user-provided instance number. For example, a command similar to create ipsec tunnel local-ip . . . instance 5 would result in the creation of interface "ipsec5". - ipsec: delete tunnel protection when asked The "ipsec tunnel protect" command will parse a "del" argument but does not undo the tunnel protection, leaving the SAs hanging around with reference counts that were incremented by a previous invocation of the command. Allow the tunnel protection to be deleted and also update the help text to indicate that deletion is an option. - test: ipsec: add test for ipsec interface instance Also cleanup (unconfig) after TestIpsecItf4 NULL algo test.
