2021-06-30memif: fix tx desc length for chained buffers in copy modeBenoît Ganne1-0/+1
When enqueuing chained buffer, we must update the descriptor length for each fragment descriptor in addition to the last. Type: fix Change-Id: I9bc95fe557a049eeea4abd41c695153632d52a52 Signed-off-by: Benoît Ganne <bganne@cisco.com>
2021-06-30rdma: fix chained buffer tx path in dv modeBenoît Ganne1-24/+20
When switching to the direct verb chain buffer tx path, we must account for all remaining packets, including the packets that would wrapped around. Previously we were using the 'n' counter but ignoring the 'n_wrap' counter: if some packets would have wrapped around in the default path, it would be ignored by the chained buffer tx path. Compute the correct number of remaining packets based on the old and current txq tail instead. Also simplify the chained tx function parameters.

2021-06-29ipsec: Fix setting the hi-sequence number for decryptNeale Ranns7-135/+229
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.

2021-06-24linux-cp: stop managing adjacencies for tunnelsAlexander Chernavin1-0/+12
Type: fix Outbound packets which arrive on tun/L3 interfaces use a default adjacency for the interface & address family from the corresponding interface pair. However, there are entries in the linux-cp adj table that are created for them. Managing these entries might cause a segfault because the rewrite data might exceed the reserved space for it of 28 bytes in the linux-cp adj key (e.g. in case of GRE IPv6). With this change, stop creating adjacencies for tun/L3 interfaces in the linux-cp adj table and delegating them.

In some part of VPP we are accessing memory past what was allocated for efficiency when we know it is safe to do so. We need to tell ASan about it so it does not complain. The initial attempt was too simple and could not manage cases where the poisoned memory was scattered. This new attempt is more robust as we save and restore the full shadow state. Note it will still not work properly if we poison/unpoison memory while in an overflow context, but this should not be a big issue as overflow should only be temporary.
