2018-10-25tcp/session: add tx pacerFlorin Coras10-21/+305
Adds tx pacing infrastructure for transport protocols that want to use it. Particularly useful for connections with non-negligible rtt and constrained network throughput as it avoids large tx bursts that lead to local interface tx or network drops. By default the pacer is disabled. To enabled it for tcp, add tx-pacing to tcp's startup conf. We are still slightly inefficient in the handling of incoming packets in established state so the pacer slightly affect maximum throughput in low lacency scenarios.

2018-10-25SCTP: DATA chunk padding fix and hardeningMarco Varlese3-7/+37
According to the RFC 4096 (section 3.3.1) the DATA chunk needs to be padded to a boundary of 4 bytes with zeros. This patch addresses that requirement. At the same time, this patch takes care of adding some hardening for corner-cases where the transmitted tag could be wrong.

Patch is too large to be ported to 18.10 just days before release. - handle fast retransmits outside of established node and limit the retransmit burst size to avoid tx losses and worsening congestion. - in the absance of a tx pacer, use slow start after fast retransmit exists - add fast retransmit heuristic that re-retries sending the first segment if everything else fails - fine tuning Change-Id: I84a2ab8fbba8b97f1d2b26584dc11a1e2c33c8d2 Signed-off-by: Florin Coras <fcoras@cisco.com>

pipe-rx node to match that of ethernet-input node Since pipe-rx is a sibling node of ethernet-input, it ought to perform similarly: set l2/l3 header offsets, and l2.l2_len value if the interface is in the l2 mode. The use cases of pipes do not assume the tagged traffic, so assume the simple ethernet header.

2018-10-15vnet: create L2 feature arc infrastructureAndrew Yourtchenko7-2/+728
This commit adds two new nodes in the L2 datapath in input and output direction respectively. These nodes fork the traffic into three feature arcs: ip4, ip6 and nonip, which later join to continue the usual L2 processing. The vnet_l2_feature_enable_disable() function with the same signature as vnet_feature_enable_disable() takes care of enabling the L2 datapath feature bits as needed, when the features are enabled/disabled. Thus, L2 features may use the similar plumbing as the L3 features enjoy. Change-Id: I76877b3a92d794c492bff1622bb26acba05705b2 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

2018-10-12vnet: complete the fix for l3_hdr_offset calculation for single loop ↵Andrew Yourtchenko1-1/+1
fastpass case (VPP-1444) 20e6d36b has moved the calculation of the l3_hdr_offset into the determine_next_node() function, with the assumption that the current_data in the buffer is at the L3 header. This is not the case for the single loop fastpath, where the vlib_buffer_advance() call is made after the call to determine_next_node(), as a day1 behavior. As a result - that path incorrectly sets the l3_hdr_offset. Solution: move the vlib_buffer_advance() call to before determine_next_node() Change-Id: Id5eaa084c43fb6564f8239df4a0b3dc0412b15de Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com> (cherry picked from commit 376414f4c3f53af44da4e82ee5d0b1843b291f8e)

2018-10-09vnet: ethernet-input incorrectly sets l3_hdr_offset in some casesAndrew Yourtchenko1-26/+26
The issue surfaced when developing the tap GSO code, with an iteration where output path is reliant on vnet_buffer (b0)->l3_hdr_offset being set correctly in the input path, during performance testing. Adding a workaround in the TX path shows that the issue surfaces only for relatively few packets during the test (about 100 out of 600000). Analysis shows the issue arises if the ethernet-input is handling two untagged packets with different sw_if_index values - then the accelerated path punts to slow path, before the setting of the l2.l2_len values is done, thus resulting in them being 0, and l3_hdr_offset being the same as l2_hdr_offset, wreaking havoc on TX path. The solution is to move the l2_hdr_offset calculation into a place where it is done for all the packets, and move the l3_hdr_offset calculation into the determine_next_node() function - as that function is also the one setting the special-case l2.l2_len value for tagged packets and moving the current_data for the L2 case.
