2020-12-18ipsec: fixed esp_decrypt pkt len after icv movedPiotrX Kleski1-6/+11
Type: fix This change makes esp_move_icv() update pd->current_length if the first buffer's length is updated. In case that ICV is split over two buffers, esp_move_icv() copies ICV to last buffer, it also updates the before_last buffer's current_length. However, in esp_decrypt_post_crypto(), pd->current_lenght is used to update first buffer lenght, but pd is not updated in esp_move_icv() and the total pkt lenght ends up incorrect. This only happens in tunnel mode when ICV is split between 1st and 2nd buffers. Signed-off-by: PiotrX Kleski <piotrx.kleski@intel.com> Change-Id: Ic39d87454ec0d022c050775acb64c5c25ccf7f13

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.

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

2020-09-07ipsec: fix padding/alignment for native IPsec encryptionChristian Hopps5-19/+19
Not all ESP crypto algorithms require padding/alignment to be the same as AES block/IV size. CCM, CTR and GCM all have no padding/alignment requirements, and the RFCs indicate that no padding (beyond ESPs 4 octet alignment requirement) should be used unless TFC (traffic flow confidentiality) has been requested. CTR: https://tools.ietf.org/html/rfc3686#section-3.2 GCM: https://tools.ietf.org/html/rfc4106#section-3.2 CCM: https://tools.ietf.org/html/rfc4309#section-3.2 - VPP is incorrectly using the IV/AES block size to pad CTR and GCM. These modes do not require padding (beyond ESPs 4 octet requirement), as a result packets will have unnecessary padding, which will waste bandwidth at least and possibly fail certain network configurations that have finely tuned MTU configurations at worst. Fix this as well as changing the field names from ".*block_size" to ".*block_align" to better represent their actual (and only) use. Rename "block_sz" in esp_encrypt to "esp_align" and set it correctly as well. test: ipsec: Add unit-test to test for RFC correct padding/alignment test: patch scapy to not incorrectly pad ccm, ctr, gcm modes as well - Scapy is also incorrectly using the AES block size of 16 to pad CCM, CTR, and GCM cipher modes. A bug report has been opened with the and acknowledged with the upstream scapy project as well: https://github.com/secdev/scapy/issues/2322 Ticket: VPP-1928 Type: fix Signed-off-by: Christian Hopps <chopps@labn.net> Change-Id: Iaa4d6a325a2e99fdcb2c375a3395bcfe7947770e
2020-09-04ipsec: fix trace of GRE_teb packetsChristian Hopps1-2/+5
The issue is not easily hit. When GRE_teb packets are received the post crypto processing adjusts the l2.l2_len value in the vnet_buffer opaque data. This is overwriting the ipsec opaque data. Later the trace code fetches the sa_index from the ipsec opaque data. It's just an accident that this currently works, if the ipsec data is changed so that the sa_index moves around it will be overwritten by the l2_len modification. Indeed, this was found b/c local development changes had moved the sa_index so it was over-lapping with the l2_len memory space, and the UT failed.

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>

Now UDP enacapsulation doesn't work in transport mode with crypto algorithms that have iv_sz=8 like AES GCM or 3DES CBC.
