One line was apparently pasted incorrectly during a new feature patch: drivers/net/phy/marvell.c:2090:15: error: initialized field overwritten [-Werror=override-init] .features = PHY_GBIT_FEATURES, I'm removing the extraneous line here to avoid the W=1 warning and restore the previous flags value, and I'm slightly reordering the lines for consistency to make it less likely to happen again in the future. The ordering in the array is still not the same as in the structure definition, instead I picked the order that is most common in this file and that seems to make more sense here.

The idea for this was born when testing VF support in iproute2 which was impeded by hardware requirements. In fact, not every VF-capable hardware driver implements all netdev ops, so testing the interface is still hard to do even with a well-sorted hardware shelf. To overcome this and allow for testing the user-kernel interface, this patch allows to turn dummy into a PF with a configurable amount of VFs. Since my patch series 'bus-agnostic-num-vf' has been accepted, implementing the required interfaces is pretty straightforward: Iff 'num_vfs' module parameter was given a value >0, a dummy bus type is being registered which implements the 'num_vf()' callback. Additionally, a dummy parent device common to all dummy devices is registered which sits on the above dummy bus. Joint work with Sabrina Dubroca. Signed-off-by:

Jiri Pirko says: ==================== Add support for offloading packet-sampling Yotam says: The first patch introduces the psample module, a netlink channel dedicated to packet sampling implemented using generic netlink. This module provides a generic way for kernel modules to sample packets, while not being tied to any specific subsystem like NFLOG. The second patch adds the sample tc action, which uses psample to randomly sample packets that match a classifier. The user can configure the psample group number, the sampling rate and the packet's truncation (to save kernel-user traffic). The last two patches add the support for offloading the matchall-sample tc command in the mlxsw driver, for ingress qdiscs. An example for psample usage can be found in the libpsample project at: https://github.com/Mellanox/libpsample v1->v2: - Reword first patch's commit message - Fix typo in comment in second patch - Change order of tc_sample uapi enum to match convention - Rename act_sample action callback tcf_sample -> tcf_sample_act ==================== Signed-off-by:

Using the MPSC register, add the functions that configure port-based packet sampling in hardware and the necessary datatypes in the mlxsw_sp_port struct. In addition, add the necessary trap for sampled packets and integrate with matchall offloading to allow offloading of the sample tc action. The current offload support is for the tc command: tc filter add dev <DEV> parent ffff: \ matchall skip_sw \ action sample rate <RATE> group <GROUP> [trunc <SIZE>] Where only ingress qdiscs are supported, and only a combination of matchall classifier and sample action will lead to activating hardware packet sampling.

This action allows the user to sample traffic matched by tc classifier. The sampling consists of choosing packets randomly and sampling them using the psample module. The user can configure the psample group number, the sampling rate and the packet's truncation (to save kernel-user traffic). Example: To sample ingress traffic from interface eth1, one may use the commands: tc qdisc add dev eth1 handle ffff: ingress tc filter add dev eth1 parent ffff: \ matchall action sample rate 12 group 4 Where the first command adds an ingress qdisc and the second starts sampling randomly with an average of one sampled packet per 12 packets on dev eth1 to psample group 4.

Add a general way for kernel modules to sample packets, without being tied to any specific subsystem. This netlink channel can be used by tc, iptables, etc. and allow to standardize packet sampling in the kernel. For every sampled packet, the psample module adds the following metadata fields: PSAMPLE_ATTR_IIFINDEX - the packets input ifindex, if applicable PSAMPLE_ATTR_OIFINDEX - the packet output ifindex, if applicable PSAMPLE_ATTR_ORIGSIZE - the packet's original size, in case it has been truncated during sampling PSAMPLE_ATTR_SAMPLE_GROUP - the packet's sample group, which is set by the user who initiated the sampling. This field allows the user to differentiate between several samplers working simultaneously and filter packets relevant to him PSAMPLE_ATTR_GROUP_SEQ - sequence counter of last sent packet. The sequence is kept for each group PSAMPLE_ATTR_SAMPLE_RATE - the sampling rate used for sampling the packets PSAMPLE_ATTR_DATA - the actual packet bits The sampled packets are sent to the PSAMPLE_NL_MCGRP_SAMPLE multicast group. In addition, add the GET_GROUPS netlink command which allows the user to see the current sample groups, their refcount and sequence number. This command currently supports only netlink dump mode.

Martin Blumenstingl says: ==================== stmmac: dwmac-meson8b: configurable RGMII TX delay Currently the dwmac-meson8b stmmac glue driver uses a hardcoded 1/4 cycle (= 2ns) TX clock delay. This seems to work fine for many boards (for example Odroid-C2 or Amlogic's reference boards) but there are some others where TX traffic is simply broken. There are probably multiple reasons why it's working on some boards while it's broken on others: - some of Amlogic's reference boards are using a Micrel PHY - hardware circuit design - maybe more... iperf3 results on my Mecool BB2 board (Meson GXM, RTL8211F PHY) with TX clock delay disabled on the MAC (as it's enabled in the PHY driver).

I get similar TX throughput on my Meson GXBB "MXQ Pro+" board when I disable the PHY's TX-delay and configure a 4ms TX-delay on the MAC. So changes to at least the RTL8211F PHY driver are needed to get it working properly in all situations. Changes since v4: - add a fallback of 2ns (the value which was previously hardcoded) for the TX delay so we are backwards-compatible with older .dts' - update the documentation with the new fallback value and add a small note that the "amlogic,tx-delay" property is ignored when the phy-mode is "rmii". Changes since v3: - rebased to apply against current net-next branch (fixes a conflict with d2ed0a77 "net: ethernet: stmmac: fix of-node and fixed-link-phydev leaks") Changes since v2: - moved all .dts patches (3-7) to a separate series - removed the default 2ns TX delay when phy-mode RGMII is specified - (rebased against current net-next) Changes since v1: - renamed the devicetree property "amlogic,tx-delay" to "amlogic,tx-delay-ns", which makes the .dts easier to read as we can simply specify human-readable values instead of having "preprocessor defines and calculation in human brain". Thanks to Andrew Lunn for the suggestion! - improved documentation to indicate when the MAC TX-delay should be configured and how to use the PHY's TX-delay - changed the default TX-delay in the dwmac-meson8b driver from 2ns to 0ms when any of the rgmii-*id modes are used (the 2ns default value still applies for phy-mode "rgmii") - added patches to properly reset the PHY on Meson GXBB devices and to use a similar configuration than the one we use on Meson GXL devices (by passing a phy-handle to stmmac and defining the PHY in the mdio0 bus - patch 3-6) - add the "amlogic,tx-delay-ns" property to all boards which are using the RGMII PHY (patch 7) ==================== Signed-off-by:

Prior to this patch we were using a hardcoded RGMII TX clock delay of 2ns (= 1/4 cycle of the 125MHz RGMII TX clock). This value works for many boards, but unfortunately not for all (due to the way the actual circuit is designed, sometimes because the TX delay is enabled in the PHY, etc.). Making the TX delay on the MAC side configurable allows us to support all possible hardware combinations. This allows fixing a compatibility issue on some boards, where the RTL8211F PHY is configured to generate the TX delay. We can now turn off the TX delay in the MAC, because otherwise we would be applying the delay twice (which results in non-working TX traffic). Signed-off-by:

This allows configuring the RGMII TX clock delay. The RGMII clock is generated by underlying hardware of the the Meson 8b / GXBB DWMAC glue. The configuration depends on the actual hardware (no delay may be needed due to the design of the actual circuit, the PHY might add this delay, etc.). Signed-off-by:

Felix Fietkau authored
Implements an optional, per bridge port flag and feature to deliver multicast packets to any host on the according port via unicast individually. This is done by copying the packet per host and changing the multicast destination MAC to a unicast one accordingly. multicast-to-unicast works on top of the multicast snooping feature of the bridge. Which means unicast copies are only delivered to hosts which are interested in it and signalized this via IGMP/MLD reports previously. This feature is intended for interface types which have a more reliable and/or efficient way to deliver unicast packets than broadcast ones (e.g. wifi). However, it should only be enabled on interfaces where no IGMPv2/MLDv1 report suppression takes place. This feature is disabled by default. The initial patch and idea is from Felix Fietkau.

Add net.ipv4.ip_unprivileged_port_start, which is a per namespace sysctl that denotes the first unprivileged inet port in the namespace. To disable all privileged ports set this to zero. It also checks for overlap with the local port range. The privileged and local range may not overlap. The use case for this change is to allow containerized processes to bind to priviliged ports, but prevent them from ever being allowed to modify their container's network configuration. The latter is accomplished by ensuring that the network namespace is not a child of the user namespace. This modification was needed to allow the container manager to disable a namespace's priviliged port restrictions without exposing control of the network namespace to processes in the user namespace.

Daniel Mack says: ==================== bpf: add longest prefix match map This patch set adds a longest prefix match algorithm that can be used to match IP addresses to a stored set of ranges. It is exposed as a bpf map type. Internally, data is stored in an unbalanced tree of nodes that has a maximum height of n, where n is the prefixlen the trie was created with. Note that this has nothing to do with fib or fib6 and is in no way meant to replace or share code with it. It's rather a much simpler implementation that is specifically written with bpf maps in mind. Patch 1/2 adds the implementation, 2/2 an extensive test suite and 3/3 has benchmarking code for the new trie type. Feedback is much appreciated. Changelog: v3 -> v4: * David added a 3rd patch that augments map_perf_test for LPM trie benchmarks * Limit allocation of maps of this new type to CAP_SYS_ADMIN for now, as requested by Alexei * Add a stub .map_delete_elem so the core does not stumble over a NULL pointer when the syscall is invoked * Tests for non-power-of-2 prefix lengths were added * More comment style fixes v2 -> v3: * Store both the key match data and the caller provided value in the same byte array attached to a node. This avoids double allocations * Bring back node->flags to distinguish between 'real' and intermediate nodes * Fix comment style and some typos v1 -> v2: * Turn spin lock into raw spinlock * Lock with irqsave options during trie_update_elem() * Return -ENOMEM properly from trie_alloc() * Force attr->flags == BPF_F_NO_PREALLOC during creation * Set trie->map.pages after creation to account for map memory * Allow arbitrary value sizes * Removed node->flags and denode intermediate nodes through node->value == NULL instead rfc -> v1: * Add __rcu pointer annotations to make sparse happy * Fold _lpm_trie_find_target_node() into its only caller * Fix some minor documentation issues ==================== Signed-off-by: -

Extend the map_perf_test_{user,kern}.c infrastructure to stress test lpm-trie lookups. We hook into the kprobe on sys_gettid() and measure the latency depending on trie size and lookup count. On my Intel Haswell i7-6400U, a single gettid() syscall with an empty bpf program takes roughly 6.5us on my system. Lookups in empty tries take ~1.8us on first try, ~0.9us on retries. Lookups in tries with 8192 entries take ~7.1us (on the first _and_ any subsequent try). Signed-off-by:David Herrmann <dh.herrmann@gmail.com> Reviewed-by:

The first part of this program runs randomized tests against the lpm-bpf-map. It implements a "Trivial Longest Prefix Match" (tlpm) based on simple, linear, single linked lists. The implementation should be pretty straightforward. Based on tlpm, this inserts randomized data into bpf-lpm-maps and verifies the trie-based bpf-map implementation behaves the same way as tlpm. The second part uses 'real world' IPv4 and IPv6 addresses and tests the trie with those. Signed-off-by:

This trie implements a longest prefix match algorithm that can be used to match IP addresses to a stored set of ranges. Internally, data is stored in an unbalanced trie of nodes that has a maximum height of n, where n is the prefixlen the trie was created with. Tries may be created with prefix lengths that are multiples of 8, in the range from 8 to 2048. The key used for lookup and update operations is a struct bpf_lpm_trie_key, and the value is a uint64_t. The code carries more information about the internal implementation. Signed-off-by:

The EMAC has an internal PHY that is often called the "SGMII". This SGMII is also connected to an external PHY, which is managed by phylib. These dual PHYs often cause confusion. In this case, the data structure for managing the SGMII was mis-named and located in the wrong header file. Structure emac_phy is renamed to emac_sgmii to clearly indicate it applies to the internal PHY only. It also also moved from emac_phy.h (which supports the external PHY) to emac_sgmii.h (where it belongs). To keep the changes minimal, only the structure name is changed, not the names of any variables of that type. Signed-off-by:
