The current selftests infrastructure formats the results in TAP 13. This version doesn't support subtests and only the end result of each selftest is taken into account. It means that a single issue in a subtest of a selftest containing multiple subtests forces the whole selftest to be marked as failed. It also means that subtests results are not tracked by CIs executing selftests. MPTCP selftests run hundreds of various subtests. It is then important to track each of them and not one result per selftest. It is particularly interesting to do that when validating stable kernels with the last version of the test suite: tests might fail because a feature is not supported but the test didn't skip that part. In this case, if subtests are not tracked, the whole selftest will be marked as failed making the other subtests useless because their results are ignored. This patch formats subtests results in TAP in diag.sh selftest. Link: https://github.com/multipath-tcp/mptcp_net-next/issues/368Acked-by:

In this selftest, "printf" is always used with "stdbuf". With a new helper, it is possible to call "stdbuf" only from one place. This makes the code a bit clearer to read. Acked-by:

Matthieu Baerts authored
There are a few reasons to do that: - When the tabs are not printed as 8 spaces, some results were not properly aligned - Some lines printing the test name were very long due to the use of a lot of spaces/tabs at the end and stdbuf at the beginning. - To reduce duplicated code, e.g. to print what has failed and set the status But by centralising how the test results are printed, this also prepares future commits to avoid more duplicated code and ease the tracking of the different subtests.

shellcheck recently helped to find an issue where a wrong variable name was used. It is then good to fix the other harmless issues in order to spot "real" ones later. Here, three categories of warnings are ignored: - SC2317: Command appears to be unreachable. The cleanup() function is invoke indirectly via the EXIT trap. - SC2034: Variable appears unused. The check_expected_one() function takes the name of the variable in argument but it ends up reading the content: indirect usage. - SC2086: Double quote to prevent globbing and word splitting. This is recommended but the current usage is correct and there is no need to do all these modifications to be compliant with this rule. One error has been fixed with SC2181: Check exit code directly with e.g. 'if ! mycmd;', not indirectly with $?. Acked-by:

Get the exact count of L3L4 filters when the L3L4FNUM field of HW_FEATURE1 register is >= 8. If L3L4FNUM < 8, then the number of L3L4 filters supported by XGMAC is equal to L3L4FNUM. From L3L4FNUM >= 8 the number of L3L4 filters goes on like 8, 16, 32, ... Current maximum of L3L4FNUM = 10. Also, fix the XGMAC_IDDR bitmask of L3L4_ADDR_CTRL register. IDDR field starts from the 8th bit of the L3L4_ADDR_CTRL register. IDDR[3:0] indicates the type of L3L4 filter register while IDDR[8:4] indicates the filter number (0 to 31). So overall 9 bits are used for IDDR (i.e. L3L4_ADDR_CTRL[16:8]) to address the registers of all the filters. Currently, XGMAC_IDDR is GENMASK(15,8), causing issues accessing L3L4 filters above 15 for those XGMACs configured with more than 16 L3L4 filters. Signed-off-by:

Ido Schimmel says: ==================== Add backup nexthop ID support tl;dr ===== This patchset adds a new bridge port attribute specifying the nexthop object ID to attach to a redirected skb as tunnel metadata. The ID is used by the VXLAN driver to choose the target VTEP for the skb. This is useful for EVPN multi-homing, where we want to redirect local (intra-rack) traffic upon carrier loss through one of the other VTEPs (ES peers) connected to the target host. Background ========== In a typical EVPN multi-homing setup each host is multi-homed using a set of links called ES (Ethernet Segment, i.e., LAG) to multiple leaf switches in a rack. These switches act as VTEPs and are not directly connected (as opposed to MLAG), but can communicate with each other (as well as with VTEPs in remote racks) via spine switches over L3. The control plane uses Type 1 routes [1] to create a mapping between an ES and VTEPs where the ES has active links. In addition, the control plane uses Type 2 routes [2] to create a mapping between {MAC, VLAN} and an ES. These tables are then used by the control plane to instruct VTEPs how to reach remote hosts. For example, assuming {MAC X, VLAN Y} is accessible via ES1 and this ES has active links to VTEP1 and VTEP2. The control plane will program the following entries to a remote VTEP: # ip nexthop add id 1 via $VTEP1_IP fdb # ip nexthop add id 2 via $VTEP2_IP fdb # ip nexthop add id 10 group 1/2 fdb # bridge fdb add $MAC_X dev vx0 master extern_learn vlan $VLAN_Y # bridge fdb add $MAC_Y dev vx0 self extern_learn nhid 10 src_vni $VNI_Y Remote traffic towards the host will be load balanced between VTEP1 and VTEP2. If the control plane notices a carrier loss on the ES1 link connected to VTEP1, it will issue a Type 1 route withdraw, prompting remote VTEPs to remove the effected nexthop from the group: # ip nexthop replace id 10 group 2 fdb Motivation ========== While remote traffic can be redirected to a VTEP with an active ES link by withdrawing a Type 1 route, the same is not true for local traffic. A host that is multi-homed to VTEP1 and VTEP2 via another ES (e.g., ES2) will send its traffic to {MAC X, VLAN Y} via one of these two switches, according to its LAG hash algorithm which is not under our control. If the traffic arrives at VTEP1 - which no longer has an active ES1 link - it will be dropped due to the carrier loss. In MLAG setups, the above problem is solved by redirecting the traffic through the peer link upon carrier loss. This is achieved by defining the peer link as the backup port of the host facing bond. For example: # bridge link set dev bond0 backup_port bond_peer Unlike MLAG, there is no peer link between the leaf switches in EVPN. Instead, upon carrier loss, local traffic should be redirected through one of the active ES peers. This can be achieved by defining the VXLAN port as the backup port of the host facing bonds. For example: # bridge link set dev es1_bond backup_port vx0 However, the VXLAN driver is not programmed with FDB entries for locally attached hosts and therefore does not know to which VTEP to redirect the traffic to. This will result in the traffic being replicated to all the VTEPs (potentially hundreds) in the network and each VTEP dropping the traffic, except for the active ES peer. Avoiding the flooding by programming local FDB entries in the VXLAN driver is not a viable solution as it requires to significantly increase the number of programmed FDB entries. Implementation ============== The proposed solution is to create an FDB nexthop group for each ES with the IP addresses of the active ES peers and set this ID as the backup nexthop ID (new bridge port attribute) of the ES link. For example, on VTEP1: # ip nexthop add id 1 via $VTEP2_IP fdb # ip nexthop add id 10 group 1 fdb # bridge link set dev es1_bond backup_nhid 10 # bridge link set dev es1_bond backup_port vx0 When the ES link loses its carrier, traffic will be redirected to the VXLAN port, but instead of only attaching the tunnel ID (i.e., VNI) as tunnel metadata to the skb, the backup nexthop ID will be attached as well. The VXLAN driver will then use this information to forward the skb via the nexthop object associated with the ID, as if the skb hit an FDB entry associated with this ID. Testing ======= A test for both the existing backup port attribute as well as the new backup nexthop ID attribute is added in patch #4. Patchset overview ================= Patch #1 extends the tunnel key structure with the new nexthop ID field. Patch #2 uses the new field in the VXLAN driver to forward packets via the specified nexthop ID. Patch #3 adds the new backup nexthop ID bridge port attribute and adjusts the bridge driver to attach the ID as tunnel metadata upon redirection. Patch #4 adds a selftest. iproute2 patches can be found here [3]. Changelog ========= Since RFC [4]: * Added Nik's tags.

Add a new bridge port attribute that allows attaching a nexthop object ID to an skb that is redirected to a backup bridge port with VLAN tunneling enabled. Specifically, when redirecting a known unicast packet, read the backup nexthop ID from the bridge port that lost its carrier and set it in the bridge control block of the skb before forwarding it via the backup port. Note that reading the ID from the bridge port should not result in a cache miss as the ID is added next to the 'backup_port' field that was already accessed. After this change, the 'state' field still stays on the first cache line, together with other data path related fields such as 'flags and 'vlgrp': struct net_bridge_port { struct net_bridge * br; /* 0 8 */ struct net_device * dev; /* 8 8 */ netdevice_tracker dev_tracker; /* 16 0 */ struct list_head list; /* 16 16 */ long unsigned int flags; /* 32 8 */ struct net_bridge_vlan_group * vlgrp; /* 40 8 */ struct net_bridge_port * backup_port; /* 48 8 */ u32 backup_nhid; /* 56 4 */ u8 priority; /* 60 1 */ u8 state; /* 61 1 */ u16 port_no; /* 62 2 */ /* --- cacheline 1 boundary (64 bytes) --- */ [...] } __attribute__((__aligned__(8))); When forwarding an skb via a bridge port that has VLAN tunneling enabled, check if the backup nexthop ID stored in the bridge control block is valid (i.e., not zero). If so, instead of attaching the pre-allocated metadata (that only has the tunnel key set), allocate a new metadata, set both the tunnel key and the nexthop object ID and attach it to the skb. By default, do not dump the new attribute to user space as a value of zero is an invalid nexthop object ID. The above is useful for EVPN multihoming. When one of the links composing an Ethernet Segment (ES) fails, traffic needs to be redirected towards the host via one of the other ES peers. For example, if a host is multihomed to three different VTEPs, the backup port of each ES link needs to be set to the VXLAN device and the backup nexthop ID needs to point to an FDB nexthop group that includes the IP addresses of the other two VTEPs. The VXLAN driver will extract the ID from the metadata of the redirected skb, calculate its flow hash and forward it towards one of the other VTEPs. If the ID does not exist, or represents an invalid nexthop object, the VXLAN driver will drop the skb. This relieves the bridge driver from the need to validate the ID. Signed-off-by: -

VXLAN FDB entries can point to FDB nexthop objects. Each such object includes the IP address(es) of remote VTEP(s) via which the target host is accessible. Example: # ip nexthop add id 1 via 192.0.2.1 fdb # ip nexthop add id 2 via 192.0.2.17 fdb # ip nexthop add id 1000 group 1/2 fdb # bridge fdb add 00:11:22:33:44:55 dev vx0 self static nhid 1000 src_vni 10020 This is useful for EVPN multihoming where a single host can be connected to multiple VTEPs. The source VTEP will calculate the flow hash of the skb and forward it towards the IP address of one of the VTEPs member in the nexthop group. There are cases where an external entity (e.g., the bridge driver) can provide not only the tunnel ID (i.e., VNI) of the skb, but also the ID of the nexthop object via which the skb should be forwarded. Therefore, in order to support such cases, when the VXLAN device is in external / collect metadata mode and the tunnel info attached to the skb is of bridge type, extract the nexthop ID from the tunnel info. If the ID is valid (i.e., non-zero), forward the skb via the nexthop object associated with the ID, as if the skb hit an FDB entry associated with this ID. Signed-off-by:

Extend the ip_tunnel_key structure with a field indicating the ID of the nexthop object via which the skb should be routed. The field is going to be populated in subsequent patches by the bridge driver in order to indicate to the VXLAN driver which FDB nexthop object to use in order to reach the target host.

With modern NIC drivers shifting to full page allocations per received frame, we face the following issue: TCP has one per-netns sysctl used to tweak how to translate a memory use into an expected payload (RWIN), in RX path. tcp_win_from_space() implementation is limited to few cases. For hosts dealing with various MSS, we either under estimate or over estimate the RWIN we send to the remote peers. For instance with the default sysctl_tcp_adv_win_scale value, we expect to store 50% of payload per allocated chunk of memory. For the typical use of MTU=1500 traffic, and order-0 pages allocations by NIC drivers, we are sending too big RWIN, leading to potential tcp collapse operations, which are extremely expensive and source of latency spikes. This patch makes sysctl_tcp_adv_win_scale obsolete, and instead uses a per socket scaling factor, so that we can precisely adjust the RWIN based on effective skb->len/skb->truesize ratio. This patch alone can double TCP receive performance when receivers are too slow to drain their receive queue, or by allowing a bigger RWIN when MSS is close to PAGE_SIZE. Signed-off-by:

It's inefficient to ring the doorbell page every time a WQE is posted to the received queue. Excessive MMIO writes result in CPU spending more time waiting on LOCK instructions (atomic operations), resulting in poor scaling performance. Move the code for ringing doorbell page to where after we have posted all WQEs to the receive queue during a callback from napi_poll(). With this change, tests showed an improvement from 120G/s to 160G/s on a 200G physical link, with 16 or 32 hardware queues. Tests showed no regression in network latency benchmarks on single connection. Reviewed-by:

The old way to do LAN reset is sending reset command to firmware. Once firmware performs reset, it reconfigures what it needs. In the new firmware versions, veto bit is introduced for NCSI/LLDP to block PHY domain in LAN reset. At this point, writing register of LAN reset directly makes the same effect as the old way. And it does not reset MNG domain, so that veto bit does not change. Since veto bit was never used, the old firmware is compatible with the driver before and after this change. The new firmware needs to use with the driver after this change if it wants to implement the new feature, otherwise it is the same as the old firmware. Signed-off-by:

Add TransmissionOverrun as per defined by IEEE 802.1Q Bridges. TransmissionOverrun counter shall be incremented if the implementation detects that a frame from a given queue is still being transmitted by the MAC when that gate-close event for that queue occurs. This counter is utilised by the Certification conformance test to inform the user application whether any packets are currently being transmitted on a particular queue during a gate-close event. Intel Discrete I225/I226 have a mechanism to not transmit a packets if the gate open time is insufficient for the packet transmission by setting the Strict_End bit. Thus, it is expected for this counter to be always zero at this moment. Inspired from enetc_taprio_stats() and enetc_taprio_queue_stats(), now driver also report the tx_overruns counter per traffic class. User can get this counter by using below command: 1) tc -s qdisc show dev <interface> root 2) tc -s class show dev <interface> Test Result (Before): class mq :1 root Sent 1289 bytes 20 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 class mq :2 root Sent 124 bytes 2 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 class mq :3 root Sent 46028 bytes 86 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 class mq :4 root Sent 2596 bytes 14 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 Test Result (After): class taprio 100:1 root Sent 8491 bytes 38 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 Transmit overruns: 0 class taprio 100:2 root Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 Transmit overruns: 0 class taprio 100:3 root Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0) backlog 0b 0p requeues 0 Transmit overruns: 0 class taprio 100:4 root Sent 994 bytes 11 pkt (dropped 0, overlimits 0 requeues 1) backlog 0b 0p requeues 1 Transmit overruns: 0 Signed-off-by:

As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree.

Create a new netconsole runtime option that prepends the kernel version in the netconsole message. This is useful to map kernel messages to kernel version in a simple way, i.e., without checking somewhere which kernel version the host that sent the message is using. If this option is selected, then the "<release>," is prepended before the netconsole message. This is an example of a netconsole output, with release feature enabled: 6.4.0-01762-ga1ba2ffe946e;12,426,112883998,-;this is a test Cc: Dave Jones <davej@codemonkey.org.uk> Signed-off-by:

Russell King says: ==================== Remove some unused phylink legacy I believe we are now in a position where some of the legacy phylink code can be removed! I believe that all DSA drivers do not make use of any pre-March 2020 phylink behaviour - all drivers now seem to set legacy_pre_march2020 to false, and the conditions that DSA sets it to true are no longer satisifed by any driver. Moreover, no one uses the .mac_an_restart() method, so this can also be removed. ==================== Link: https://lore.kernel.org/r/ZLERQ2OBrv44Ppyc@shell.armlinux.org.ukSigned-off-by:

The mac_an_restart() method is now completely unused, and has been superseded by phylink_pcs support. Remove this method. Since phylink_pcs_mac_an_restart() now only deals with the PCS, rename the function to remove the _mac infix. Signed-off-by:

Since DSA no longer marks anything as phylink-legacy, there is now no need for DSA drivers to set this member to false. Remove all instances of this. Signed-off-by:
