| 2019-12-13 | netdev: pass the stuck queue to the timeout handler | Michael S. Tsirkin | 227 | -285/+287 | |

The patch was generated with the following script: use strict; use warnings; our $^I = '.bak'; my @work = ( ["arch/m68k/emu/nfeth.c", "nfeth_tx_timeout"], ["arch/um/drivers/net_kern.c",

Without the full capabilities, we may end up failing a module that we could otherwise drive with a restricted set of capabilities. An example of this would be a module with a NBASE-T PHY plugged into a host that supports phy interface modes 2500BASE-X and SGMII. The PHY supports 10GBASE-R, 5000BASE-X, 2500BASE-X, SGMII interface modes, which means a subset of the capabilities are compatible with the host. However, reading the module EEPROM leads us to believe that the module only supports ethtool link mode 10GBASE-T, which is incompatible with the host - and thus results in the module being rejected. This patch adds an extra notification which are triggered after the SFP module's PHY probe, and a corresponding notification just before the PHY is removed.

| 2019-12-11 | tipc: introduce variable window congestion control | Jon Maloy | 9 | -79/+160 | |
| We introduce a simple variable window congestion control for links. The algorithm is inspired by the Reno algorithm, covering both 'slow start', 'congestion avoidance', and 'fast recovery' modes. - We introduce hard lower and upper window limits per link, still different and configurable per bearer type. - We introduce a 'slow start theshold' variable, initially set to the maximum window size. - We let a link start at the minimum congestion window, i.e. in slow start mode, and then let is grow rapidly (+1 per rceived ACK) until it reaches the slow start threshold and enters congestion avoidance mode. - In congestion avoidance mode we increment the congestion window for each window-size number of acked packets, up to a possible maximum equal to the configured maximum window. - For each non-duplicate NACK received, we drop back to fast recovery mode, by setting the both the slow start threshold to and the congestion window to (current_congestion_window / 2). - If the timeout handler finds that the transmit queue has not moved since the previous timeout, it drops the link back to slow start and forces a probe containing the last sent sequence number to the sent to the peer, so that this can discover the stale situation. This change does in reality have effect only on unicast ethernet transport, as we have seen that there is no room whatsoever for increasing the window max size for the UDP bearer. For now, we also choose to keep the limits for the broadcast link unchanged and equal. This algorithm seems to give a 50-100% throughput improvement for messages larger than MTU.

| 2019-12-11 | tipc: eliminate more unnecessary nacks and retransmissions | Jon Maloy | 1 | -1/+5 | |
| When we increase the link tranmsit window we often observe the following scenario: 1) A STATE message bypasses a sequence of traffic packets and arrives far ahead of those to the receiver. STATE messages contain a 'peers_nxt_snt' field to indicate which was the last packet sent from the peer. This mechanism is intended as a last resort for the receiver to detect missing packets, e.g., during very low traffic when there is no packet flow to help early loss detection. 3) The receiving link compares the 'peer_nxt_snt' field to its own 'rcv_nxt', finds that there is a gap, and immediately sends a NACK message back to the peer. 4) When this NACKs arrives at the sender, all the requested retransmissions are performed, since it is a first-time request. Just like in the scenario described in the previous commit this leads to many redundant retransmissions, with decreased throughput as a consequence. We fix this by adding two more conditions before we send a NACK in this sitution. First, the deferred queue must be empty, so we cannot assume that the potential packet loss has already been detected by other means. Second, we check the 'peers_snd_nxt' field only in probe/ probe_reply messages, thus turning this into a true mechanism of last resort as it was really meant to be.

| 2019-12-11 | tipc: eliminate gap indicator from ACK messages | Jon Maloy | 1 | -5/+9 | |
| When we increase the link send window we sometimes observe the following scenario: 1) A packet #N arrives out of order far ahead of a sequence of older packets which are still under way. The packet is added to the deferred queue. 2) The missing packets arrive in sequence, and for each 16th of them an ACK is sent back to the receiver, as it should be. 3) When building those ACK messages, it is checked if there is a gap between the link's 'rcv_nxt' and the first packet in the deferred queue. This is always the case until packet number #N-1 arrives, and a 'gap' indicator is added, effectively turning them into NACK messages. 4) When those NACKs arrive at the sender, all the requested retransmissions are done, since it is a first-time request. This sometimes leads to a huge amount of redundant retransmissions, causing a drop in max throughput. This problem gets worse when we in a later commit introduce variable window congestion control, since it drops the link back to 'fast recovery' much more often than necessary. We now fix this by not sending any 'gap' indicator in regular ACK messages. We already have a mechanism for sending explicit NACKs in place, and this is sufficient to keep up the packet flow.

| This code changes the TI specific ti,fifo-depth to the common tx-fifo-depth property. The tx depth is applicable for both RGMII and SGMII modes of operation. rx-fifo-depth was added as well but this is only applicable for SGMII mode. So in summary if RGMII mode write tx fifo depth only if SGMII mode write both rx and tx fifo depths If the property is not populated in the device tree then set the value to the default values.

| 2019-12-10 | net-tcp: Disable TCP ssthresh metrics cache by default | Kevin(Yudong) Yang | 5 | -4/+24 | |
| This patch introduces a sysctl knob "net.ipv4.tcp_no_ssthresh_metrics_save" that disables TCP ssthresh metrics cache by default. Other parts of TCP metrics cache, e.g. rtt, cwnd, remain unchanged. As modern networks becoming more and more dynamic, TCP metrics cache today often causes more harm than benefits. For example, the same IP address is often shared by different subscribers behind NAT in residential networks. Even if the IP address is not shared by different users, caching the slow-start threshold of a previous short flow using loss-based congestion control (e.g. cubic) often causes the future longer flows of the same network path to exit slow-start prematurely with abysmal throughput. Caching ssthresh is very risky and can lead to terrible performance. Therefore it makes sense to make disabling ssthresh caching by default and opt-in for specific networks by the administrators. This practice also has worked well for several years of deployment with CUBIC congestion control at Google.

It's a better way to get netns from asoc and ep base, comparing to calling sock_net(). This patch is to replace them. v1->v2: - no change.
