Russell King says: ==================== Add support for SFP+ copper modules This series adds support for Copper SFP+ modules with Clause 45 PHYs. Specifically the patches: 1. drop support for the probably never tested 100BASE-*X modules. 2. drop EEPROM ID from sfp_select_interface() 3. add more compliance code definitions from SFF-8024, renaming the existing definitions. 4. add module start/stop methods so phylink knows when a module is about to become active. The module start method is called after we have probed for a PHY on the module. 5. move start/stop of module PHY down into phylink using the new module start/stop methods. 6. add support for Clause 45 I2C accesses, tested with Methode DM7052. Other modules appear to use the same protocol, but slight differences, but I do not have those modules to test with. (if someone does, please holler!) 7. rearrange how we attach to PHYs so that we can support Clause 45 PHYs with indeterminant interface modes. (Clause 45 PHYs appear to like to change their PHY interface mode depending on the negotiated speed.) 8. add support for phylink to connect to a clause 45 PHY on a SFP module. 9. split the link_an_mode between the configured value and the currently selected mode value; some clause 45 PHYs have no capability to provide in-band negotiation. 10. split the link configuration on SFP module insertion in phylink so we can use it in other code paths. 11. delay MAC configuration for copper modules without a PHY to the module start method - after any module PHY has been probed. If the module has a PHY, then we setup the MAC when the PHY is detected. 12. the Broadcom 84881 PHY does not support in-band negotiation even though it uses SGMII and 2500BASE-X. Having the MAC operating with in-band negotiation enabled, even with AN bypass enabled, results in no link - Broadcom say that the host MAC must always be forced. 13. add support for the Broadcom 84881 PHY found on the Methode DM7052 module. 14. add support to SFP to probe for a Clause 45 PHY on copper SFP+ modules. v3: now bisectable! ==================== Signed-off-by: -

The Broadcom BCM84881 does not appear to send the SGMII control word when operating in SGMII mode, which causes network adapters to fail to link with the PHY, or decide to operate at fixed 1G speed, even if the PHY negotiated 100M. Work around this by detecting the Broadcom BCM84881 and switch to phy mode rather than inband mode. Reviewed-by:

Knowing whether we need to delay the MAC configuration because a module may have a PHY is useful to phylink to allow NBASE-T modules to work on systems supporting no more than 2.5G speeds. This commit allows us to delay such configuration until after the PHY has been probed by recording the parsed capabilities, and if the module may have a PHY, doing no more until the module_start() notification is called. At that point, we either have a PHY, or we don't. We move the PHY-based setup a little later, and use the PHYs support capabilities rather than the EEPROM parsed capabilities to determine whether we can support the PHY. Reviewed-by:

Some SFP+ modules have Clause 45 PHYs embedded on them, which need a little more handling in order to ensure that they are correctly setup, as they switch the PHY link mode according to the negotiated speed. With Clause 22 PHYs, we assumed that they would operate in SGMII mode, but this assumption is now false. Adapt phylink to support Clause 45 PHYs on SFP+ modules. Reviewed-by:

In order to support Clause 45 PHYs on SFP+ modules, which have an indeterminant phy interface mode, we need to be able to call phylink_bringup_phy() with a different interface mode to that used when binding the PHY. Reduce __phylink_connect_phy() to an attach operation, and move the call to phylink_bringup_phy() to its call sites. Reviewed-by:

Some SFP+ modules have PHYs on them just like SFP modules do, except they are Clause 45 PHYs. The I2C protocol used to access them is modified slightly in order to send the device address and 16-bit register index. Reviewed-by:

Move phy_start() and phy_stop() into the module_start and module_stop notifications in phylink, rather than having them in the SFP code. This gives phylink responsibility for controlling the PHY, rather than having SFP start and stop the PHY state machine. Reviewed-by:

When dealing with some copper modules, we can't positively know the module capabilities are until we have probed the PHY. 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. Reviewed-by:

The 100BASE-FX and 100BASE-LX support assumes a PHY is present; this is probably an incorrect assumption. In any case, sfp_parse_support() will fail such a module. Let's stop pretending we support these modules. Reviewed-by:

When a TCP socket is created, sk->sk_state is initialized twice as TCP_CLOSE in sock_init_data() and tcp_init_sock(). The tcp_init_sock() is always called after the sock_init_data(), so it is not necessary to update sk->sk_state in the tcp_init_sock(). Before v2.1.8, the code of the two functions was in the inet_create(). In the patch of v2.1.8, the tcp_v4/v6_init_sock() were added and the code of initialization of sk->state was duplicated.

Jon Maloy says: ==================== tipc: introduce variable window congestion control We improve thoughput greatly by introducing a variety of the Reno congestion control algorithm at the link level. ==================== Signed-off-by: -
Jon Maloy authored
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. Suggested-by:

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. Acked-by:

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.

Dan Murphy says: ==================== Fix Tx/Rx FIFO depth for DP83867 The DP83867 supports both the RGMII and SGMII modes. The Tx and Rx FIFO depths are configurable in these modes but may not applicable for both modes. When the device is configured for RGMII mode the Tx FIFO depth is applicable and for SGMII mode both Tx and Rx FIFO depth settings are applicable. When the driver was originally written only the RGMII device was available and there were no standard fifo-depth DT properties. The patchset converts the special ti,fifo-depth property to the standard tx-fifo-depth property while still allowing the ti,fifo-depth property to be set as to maintain backward compatibility. In addition to this change the rx-fifo-depth property support was added and only written when the device is configured for SGMII mode. ==================== Signed-off-by: -

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.

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. Acked-by:

WireGuard is a layer 3 secure networking tunnel made specifically for the kernel, that aims to be much simpler and easier to audit than IPsec. Extensive documentation and description of the protocol and considerations, along with formal proofs of the cryptography, are available at: * https://www.wireguard.com/ * https://www.wireguard.com/papers/wireguard.pdf This commit implements WireGuard as a simple network device driver, accessible in the usual RTNL way used by virtual network drivers. It makes use of the udp_tunnel APIs, GRO, GSO, NAPI, and the usual set of networking subsystem APIs. It has a somewhat novel multicore queueing system designed for maximum throughput and minimal latency of encryption operations, but it is implemented modestly using workqueues and NAPI. Configuration is done via generic Netlink, and following a review from the Netlink maintainer a year ago, several high profile userspace tools have already implemented the API. This commit also comes with several different tests, both in-kernel tests and out-of-kernel tests based on network namespaces, taking profit of the fact that sockets used by WireGuard intentionally stay in the namespace the WireGuard interface was originally created, exactly like the semantics of userspace tun devices. See wireguard.com/netns/ for pictures and examples. The source code is fairly short, but rather than combining everything into a single file, WireGuard is developed as cleanly separable files, making auditing and comprehension easier. Things are laid out as follows: * noise.[ch], cookie.[ch], messages.h: These implement the bulk of the cryptographic aspects of the protocol, and are mostly data-only in nature, taking in buffers of bytes and spitting out buffers of bytes. They also handle reference counting for their various shared pieces of data, like keys and key lists. * ratelimiter.[ch]: Used as an integral part of cookie.[ch] for ratelimiting certain types of cryptographic operations in accordance with particular WireGuard semantics. * allowedips.[ch], peerlookup.[ch]: The main lookup structures of WireGuard, the former being trie-like with particular semantics, an integral part of the design of the protocol, and the latter just being nice helper functions around the various hashtables we use. * device.[ch]: Implementation of functions for the netdevice and for rtnl, responsible for maintaining the life of a given interface and wiring it up to the rest of WireGuard. * peer.[ch]: Each interface has a list of peers, with helper functions available here for creation, destruction, and reference counting. * socket.[ch]: Implementation of functions related to udp_socket and the general set of kernel socket APIs, for sending and receiving ciphertext UDP packets, and taking care of WireGuard-specific sticky socket routing semantics for the automatic roaming. * netlink.[ch]: Userspace API entry point for configuring WireGuard peers and devices. The API has been implemented by several userspace tools and network management utility, and the WireGuard project distributes the basic wg(8) tool. * queueing.[ch]: Shared function on the rx and tx path for handling the various queues used in the multicore algorithms. * send.c: Handles encrypting outgoing packets in parallel on multiple cores, before sending them in order on a single core, via workqueues and ring buffers. Also handles sending handshake and cookie messages as part of the protocol, in parallel. * receive.c: Handles decrypting incoming packets in parallel on multiple cores, before passing them off in order to be ingested via the rest of the networking subsystem with GRO via the typical NAPI poll function. Also handles receiving handshake and cookie messages as part of the protocol, in parallel. * timers.[ch]: Uses the timer wheel to implement protocol particular event timeouts, and gives a set of very simple event-driven entry point functions for callers. * main.c, version.h: Initialization and deinitialization of the module. * selftest/*.h: Runtime unit tests for some of the most security sensitive functions. * tools/testing/selftests/wireguard/netns.sh: Aforementioned testing script using network namespaces. This commit aims to be as self-contained as possible, implementing WireGuard as a standalone module not needing much special handling or coordination from the network subsystem. I expect for future optimizations to the network stack to positively improve WireGuard, and vice-versa, but for the time being, this exists as intentionally standalone. We introduce a menu option for CONFIG_WIREGUARD, as well as providing a verbose debug log and self-tests via CONFIG_WIREGUARD_DEBUG. Signed-off-by:
