The cipso_v4_cache is allocated to contain CIPSO_V4_CACHE_BUCKETS buckets. The CIPSO_V4_CACHE_BUCKETS = 1 << CIPSO_V4_CACHE_BUCKETBITS, where CIPSO_V4_CACHE_BUCKETBITS = 7. The bucket-selection function for this hash is calculated like this: bkt = hash & (CIPSO_V4_CACHE_BUCKETBITS - 1); ^^^ i.e. picking only 4 buckets of possible 128 :) Signed-off-by:Pavel Emelyanov <xemul@openvz.org> Acked-by:

If receiver consumes segments successfully only in-order, FRTO fallback to conventional recovery produces RTO loop because FRTO's forward transmissions will always get dropped and need to be resent, yet by default they're not marked as lost (which are the only segments we will retransmit in CA_Loss). Price to pay about this is occassionally unnecessarily retransmitting the forward transmission(s). SACK blocks help a bit to avoid this, so it's mainly a concern for NewReno case though SACK is not fully immune either. This change has a side-effect of fixing SACKFRTO problem where it didn't have snd_nxt of the RTO time available anymore when fallback become necessary (this problem would have only occured when RTO would occur for two or more segments and ECE arrives in step 3; no need to figure out how to fix that unless the TODO item of selective behavior is considered in future).

It seems that commit 009a2e3e ("[TCP] FRTO: Improve interoperability with other undo_marker users") run into another land-mine which caused fallback to conventional recovery to break: 1. Cumulative ACK arrives after FRTO retransmission 2. tcp_try_to_open sees zero retrans_out, clears retrans_stamp which should be kept like in CA_Loss state it would be 3. undo_marker change allowed tcp_packet_delayed to return true because of the cleared retrans_stamp once FRTO is terminated causing LossUndo to occur, which means all loss markings FRTO made are reverted. This means that the conventional recovery basically recovered one loss per RTT, which is not that efficient. It was quite unobvious that the undo_marker change broken something like this, I had a quite long session to track it down because of the non-intuitiviness of the bug (luckily I had a trivial reproducer at hand and I was also able to learn to use kprobes in the process as well :-)). This together with the NewReno+FRTO fix and FRTO in-order workaround this fixes Damon's problems, this and the first mentioned are enough to fix Bugzilla #10063. Signed-off-by:
