The expect check function __nf_ct_expect_check() asks the master_help is necessary. So it is unnecessary to go ahead in ctnetlink_alloc_expect when there is no help. Actually the commit bc01befd ("netfilter: ctnetlink: add support for user-space expectation helpers") permits ctnetlink create one expect even though there is no master help. But the latter commit 3d058d7b ("netfilter: rework user-space expectation helper support") disables it again.

People are using bonding over Infiniband IPoIB connections, and who knows what else. Infiniband has a hardware address length of 20 octets (INFINIBAND_ALEN), and the network core defines a MAX_ADDR_LEN of 32. Various places in the bonding code are currently hard-wired to 6 octets (ETH_ALEN), such as the 3ad code, which I've left untouched here. Besides, only alb is currently possible on Infiniband links right now anyway, due to commit 1533e773, so the alb code is where most of the changes are. One major component of this change is the addition of a bond_hw_addr_copy function that takes a length argument, instead of using ether_addr_copy everywhere that hardware addresses need to be copied about. The other major component of this change is converting the bonding code from using struct sockaddr for address storage to struct sockaddr_storage, as the former has an address storage space of only 14, while the latter is 128 minus a few, which is necessary to support bonding over device with up to MAX_ADDR_LEN octet hardware addresses. Additionally, this probably fixes up some memory corruption issues with the current code, where it's possible to write an infiniband hardware address into a sockaddr declared on the stack. Lightly tested on a dual mlx4 IPoIB setup, which properly shows a 20-octet hardware address now: $ cat /proc/net/bonding/bond0 Ethernet Channel Bonding Driver: v3.7.1 (April 27, 2011) Bonding Mode: fault-tolerance (active-backup) (fail_over_mac active) Primary Slave: mlx4_ib0 (primary_reselect always) Currently Active Slave: mlx4_ib0 MII Status: up MII Polling Interval (ms): 100 Up Delay (ms): 100 Down Delay (ms): 100 Slave Interface: mlx4_ib0 MII Status: up Speed: Unknown Duplex: Unknown Link Failure Count: 0 Permanent HW addr: 80:00:02:08:fe:80:00:00:00:00:00:00:e4:1d:2d:03:00:1d:67:01 Slave queue ID: 0 Slave Interface: mlx4_ib1 MII Status: up Speed: Unknown Duplex: Unknown Link Failure Count: 0 Permanent HW addr: 80:00:02:09:fe:80:00:00:00:00:00:01:e4:1d:2d:03:00:1d:67:02 Slave queue ID: 0 Also tested with a standard 1Gbps NIC bonding setup (with a mix of e1000 and e1000e cards), running LNST's bonding tests.

Currently the reordering SNMP counters only increase if a connection sees a higher degree then it has previously seen. It ignores if the reordering degree is not greater than the default system threshold. This significantly under-counts the number of reordering events and falsely convey that reordering is rare on the network. This patch properly and faithfully records the number of reordering events detected by the TCP stack, just like the comment says "this exciting event is worth to be remembered". Note that even so TCP still under-estimate the actual reordering events because TCP requires TS options or certain packet sequences to detect reordering (i.e. ACKing never-retransmitted sequence in recovery or disordered state).

If the mc_list is longer than 256 addresses, we enter mc_promisc mode. If we're in mc_promisc mode and the firmware doesn't support cascaded multicast, normally we also insert our mc_list, to prevent stealing by another VI. However, if the mc_list was too long, this isn't really helpful - the MC groups that didn't fit in the list can still get stolen, and having only some of them stealable will probably cause more confusing behaviour than having them all stealable. Since inserting 256 multicast filters takes a long time and can lead to MCDI state machine timeouts, just skip the mc_list insert in this overflow condition.

Jakub Kicinski says: ==================== nfp: ethtool link settings This series adds support for getting and setting link settings via the (moderately) new ethtool ksettings ops. First patch introduces minimal speed and duplex reporting using the information directly provided in PCI BAR0 memory. Next few changes deal with the need to refresh port state read from the service process and patch 6 finally uses that information to provide link speed and duplex. Patches 7 and 8 add auto negotiation and port type reporting. Remaining changes provide the set support for speed and auto negotiation. An upcoming series will also add port splitting support via devlink. Quite a bit of churn in this series is caused by the fact that currently port speed and split changes will usually require a reboot to take effect. Current service process code is not capable of performing MAC reinitialization after chip has been passing traffic. To make sure user is aware of this limitation we refuse the configuration unless netdev is down, print warning to the logs and if configuration was performed but did take effect we unregister the netdev. Service process has a "reboot needed" sticky bit, so reloading the driver will not bring the netdev back. Note that there is a helper in patch 13 which is marked as __always_inline, because the FIELD_* macros require the parameters to be known at compilation time. I hope that is OK. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

NSP commands may be slow to respond, we should try to avoid doing a command-per-item when user requested to change multiple parameters for instance with an ethtool .set_settings() command. Introduce a way of internal NSP code to carry state in NSP structure and add start/finish calls to perform the initialization and kick off of the configuration request, with potentially many parameters being modified in between. nfp_eth_set_mod_enable() will make use of the new code internally, other "set" functions to follow.

This version supports all events that we currently generate. I will also update my patch to iproute that will show this data through 'ip monitor'.

When netdev events happen, a rtnetlink_event() handler will send messages for every event in it's white list. These messages contain current information about a particular device, but they do not include the iformation about which event just happened. The consumer of the message has to try to infer this information. In some cases (ex: NETDEV_NOTIFY_PEERS), that is not possible. This patch adds a new extension to RTM_NEWLINK message called IFLA_EVENT that would have an encoding of the which event triggered this message. This would allow the the message consumer to easily determine if it is interested in a particular event or not. Signed-off-by: NVladislav Yasevich <vyasevic@redhat.com> Signed-off-by: NDavid S.

As a result, events have been added to the system that userspace probably doesn't care about.

Earlier patch c4adfc82 ("bonding: make speed, duplex setting consistent with link state") made an attempt to keep slave state consistent with speed and duplex settings. Unfortunately link-state transition is used to change the active link especially when used in conjunction with mii-mon. The above mentioned patch broke that logic. Also when speed and duplex settings for a link are updated during a link-event, the link-status should not be changed to invoke correct transition logic. This patch fixes this issue by moving the link-state update outside of the bond_update_speed_duplex() fn and to the places where this fn is called and update link-state selectively.
