2021-06-29ipsec: Fix setting the hi-sequence number for decryptNeale Ranns1-6/+6
Type: fix two problems; 1 - just because anti-reply is not enabled doesn't mean the high sequence number should not be used. - fix, there needs to be some means to detect a wrapped packet, so we use a window size of 2^30. 2 - The SA object was used as a scratch pad for the high-sequence number used during decryption. That means that once the batch has been processed the high-sequence number used is lost. This means it is not possible to distinguish this case: if (seq < IPSEC_SA_ANTI_REPLAY_WINDOW_LOWER_BOUND (tl)) { ... if (post_decrypt) { if (hi_seq_used == sa->seq_hi) /* the high sequence number used to succesfully decrypt this * packet is the same as the last-sequnence number of the SA. * that means this packet did not cause a wrap. * this packet is thus out of window and should be dropped */ return 1; else /* The packet decrypted with a different high sequence number * to the SA, that means it is the wrap packet and should be * accepted */ return 0; } - fix: don't use the SA as a scratch pad, use the 'packet_data' - the same place that is used as the scratch pad for the low sequence number. other consequences: - An SA doesn't have seq and last_seq, it has only seq; the sequence numnber of the last packet tx'd or rx'd. - there's 64bits of space available on the SA's first cache line. move the AES CTR mode IV there. - test the ESN/AR combinations to catch the bugs this fixes. This doubles the amount of tests, but without AR on they only run for 2 seconds. In the AR tests, the time taken to wait for packets that won't arrive is dropped from 1 to 0.2 seconds thus reducing the runtime of these tests from 10-15 to about 5 sceonds.

2021-06-28ipsec: Split the SA add_del API into an separate add and delNeale Ranns1-35/+79

2021-03-05ipsec: Support async mode per-SANeale Ranns1-1/+0
Type: feature This feautre only applies to ESP not AH SAs. As well as the gobal switch for ayncs mode, allow individual SAs to be async. If global async is on, all SAs are async. If global async mode is off, then if then an SA can be individually set to async. This preserves the global switch behaviour. the stratergy in the esp encrypt.decrypt nodes is to separate the frame into, 1) sync buffers, 2) async buffers and 3) no-op buffers. Sync buffer will undergo a cyrpto/ath operation, no-op will not, they are dropped or handed-off. Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: Ifc15b10b870b19413ad030ce7f92ed56275d6791

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>

Polling the stats segment is much more efficient (if the SA lifetime is based on packet/bytes) - emit the policy index in the packet trace and CLI commands.
