2020-09-30ikev2: better packet parsing functionsFilip Tehlar1-0/+24
Ticket: VPP-1918 Type: improvement Change-Id: I2bc3e30121697404dcd54f1c2127bd85ccc1029e Signed-off-by: Filip Tehlar <ftehlar@cisco.com>
2020-09-07ipsec: fix padding/alignment for native IPsec encryptionChristian Hopps2-30/+76
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

2019-07-24ipsec: GCM, Anti-replay and ESN fixessNeale Ranns1-23/+29
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>
