Michal Kubecek says: ==================== netlink: strict attribute checking follow-up Three follow-up patches for recent strict netlink validation series. Patch 1 fixes dump handling for genetlink families which validate and parse messages themselves (e.g. because they need different policies for diferent commands). Patch 2 sets bad_attr in extack in one place where this was omitted. Patch 3 adds new NL_VALIDATE_NESTED flags for strict validation to enable checking that NLA_F_NESTED value in received messages matches expectations and includes this flag in NL_VALIDATE_STRICT. This would change userspace visible behavior but the previous switching to NL_VALIDATE_STRICT for new code is still only in net-next at the moment. v2: change error messages to mention NLA_F_NESTED explicitly ==================== Signed-off-by: David S.

Unlike do requests, dump genetlink requests now perform strict validation by default even if the genetlink family does not set policy and maxtype because it does validation and parsing on its own (e.g. because it wants to allow different message format for different commands). While the null policy will be ignored, maxtype (which would be zero) is still checked so that any attribute will fail validation. The solution is to only call __nla_validate() from genl_family_rcv_msg() if family->maxtype is set.

Ido Schimmel says: ==================== mlxsw: Firmware version update This patchset updates mlxsw to use a new firmware version and adds support for split into two ports on Spectrum-2 based systems. Patch #1 updates the firmware version to 13.2000.1122 Patch #2 queries new resources from the firmware. Patch #3 makes use of these resources in order to support split into two ports on Spectrum-2 based systems. The need for these resources is explained by Shalom: When splitting a port, different local ports need to be mapped on different systems. For example: SN3700 (local_ports_in_2x=2): * Without split: front panel 1 --> local port 1 front panel 2 --> local port 5 * Split to 2: front panel 1s0 --> local port 1 front panel 1s1 --> local port 3 front panel 2 --> local port 5 SN3800 (local_ports_in_2x=1): * Without split: front panel 1 --> local port 1 front panel 2 --> local port 3 * Split to 2: front panel 1s0 --> local port 1 front panel 1s1 --> local port 2 front panel 2 --> local port 3 The local_ports_in_{1x, 2x} resources provide the offsets from the base local ports according to which the new local ports can be calculated. ==================== Signed-off-by: David S.

TIPC link can temporarily fall into "half-establish" that only one of the link endpoints is ESTABLISHED and starts to send traffic, PROTOCOL messages, whereas the other link endpoint is not up (e.g. immediately when the endpoint receives ACTIVATE_MSG, the network interface goes down...). This is a normal situation and will be settled because the link endpoint will be eventually brought down after the link tolerance time. However, the situation will become worse when the second link is established before the first link endpoint goes down, For example: 1. Both links <1A-2A>, <1B-2B> down 2. Link endpoint 2A up, but 1A still down (e.g. due to network disturbance, wrong session, etc.) 3. Link <1B-2B> up 4. Link endpoint 2A down (e.g. due to link tolerance timeout) 5. Node B starts failover onto link <1B-2B> ==> Node A does never start link failover. When the "half-failover" situation happens, two consequences have been observed: a) Peer link/node gets stuck in FAILINGOVER state; b) Traffic or user messages that peer node is trying to failover onto the second link can be partially or completely dropped by this node. The consequence a) was actually solved by commit c140eb16 ("tipc: fix failover problem"), but that commit didn't cover the b). It's due to the fact that the tunnel link endpoint has never been prepared for a failover, so the 'l->drop_point' (and the other data...) is not set correctly. When a TUNNEL_MSG from peer node arrives on the link, depending on the inner message's seqno and the current 'l->drop_point' value, the message can be dropped (- treated as a duplicate message) or processed. At this early stage, the traffic messages from peer are likely to be NAME_DISTRIBUTORs, this means some name table entries will be missed on the node forever! The commit resolves the issue by starting the FAILOVER process on this node as well. Another benefit from this solution is that we ensure the link will not be re-established until the failover ends.

I got an interesting report [0] that after resuming from hibernation the link has 100Mbps instead of 1Gbps. Reason is that another OS has been used whilst Linux was hibernated. And this OS speeds down the link due to WoL. Therefore, when resuming, we shouldn't expect that what the PHY advertises is what it did when hibernating. Easiest way to do this is removing state PHY_RESUMING. Instead always go via PHY_UP that configures PHY advertisement.

When probing the phy device we set sym and asym pause in the "supported" bitmap (unless the PHY tells us otherwise). However we don't know yet whether the MAC supports pause. Simply copying phy->supported to phy->advertising will trigger advertising pause, and that's not what we want. Therefore add phy_advertise_supported() that copies all modes but doesn't touch the pause bits. In phy_support_(a)sym_pause we shouldn't set any bits in the supported bitmap because we may set a bit the PHY intentionally disabled. Effective pause support should be the AND-combined PHY and MAC pause capabilities. If the MAC supports everything, then it's only relevant what the PHY supports. If MAC supports sym pause only, then we have to clear the asym bit in phydev->supported. Copy the pause flags only and don't touch the modes, because a driver may have intentionally removed a mode from phydev->advertising.

Although devlink health report does a nice job on reporting TX timeout and other NIC errors, unfortunately it requires drivers to support it but currently only mlx5 has implemented it. Before other drivers could catch up, it is useful to have a generic tracepoint to monitor this kind of TX timeout. We have been suffering TX timeout with different drivers, we plan to start to monitor it with rasdaemon which just needs a new tracepoint.

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2019-05-02 This series contains updates to the ice driver only. Anirudh introduces the framework to store queue specific information in the VSI queue contexts. This will allow future changes to update the structure to hold queue specific information. Akeem adds additional check so that if there is no queue to disable when attempting to disable a queue, return a configuration error without acquiring the lock. Fixed an issue with non-trusted VFs being able to add more than the permitted number of VLANs. Bruce removes unreachable code and updated the function to return void since it would never return anything but success. Brett provides most of the changes in the series, starting with reducing the scope of the error variable used and improved the debug message if we fail to configure the receive queue. Updates the driver to use a macro instead of using the same 'for' loop throughout the driver which helps with readability. Fixed an issue where users were led to believe they could set rx-usecs-high value, yet the changes to this value would not stick because it was not yet implemented to allow changes to this value, so implement the missing code to change the value. Found we had unnecessary wait when disabling queues, so remove it. I,proved a wasteful addition operation in our hot path by adding a member to the ice_q_vector structure and the necessary changes to use the member which stores the calculated vector hardware index. Refactored the link event flow to make it cleaner and more clear. Maciej updates the array index when stopping transmit rings, so that process every ring the VSI, not just the rings in a given transmit class. Paul adds support for setting 52 byte RSS hash keys. Md Fahad cleaned up a runtime change to the PFINT_OICR_ENA register, since the interrupt handlers will handle resetting the bit, if necessary. Tony adds a missing PHY type, which was causing warning message about an unrecognized PHY. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Previously, we can only identify copper and fiber type, the supported link modes of port information are always showing SR type. This patch adds support for multiple media types, include SR, LR CR, KR. Driver needs to query the media type from firmware periodicly, and updates the port information.

This patch introduces "recovery mode" to the i40e driver. It is part of a new Any2Any idea of upgrading the firmware. In this approach, it is required for the driver to have support for "transition firmware", that is used for migrating from structured to flat firmware image. In this new, very basic mode, i40e driver must be able to handle particular IOCTL calls from the NVM Update Tool and run a small set of AQ commands. These additional AQ commands are part of the interface used by the NVMUpdate tool. The NVMUpdate tool contains all of the necessary logic to reference these new AQ commands. The end user experience remains the same, they are using the NVMUpdate tool to update the NVM contents.

A refactor of the i40e_vc_config_promiscuous_mode_msg function moved the check for un-trusted VF into another function. We have to lie to an un-trusted VF that its request to set promiscuous mode is successful even when it is not because we don't want the VF to find out its trust status this way. With the refactor, we were running into a case where even though we were not setting promiscuous mode for an un-trusted VF, we still printed a misleading message that it was successful. This patch fixes that by ensuring that a success message is printed on the host side only when the promiscuous mode change has been successful.

The function i40e_validate_cloud_filter checks that the destination and source port numbers are valid by attempting to ensure that the number is non-zero and no larger than 0xFFFF. However, the types for the dst_port and src_port variable are __be16 which by definition cannot be larger than 0xFFFF Since these values cannot be larger than 2 bytes, the check to see if they exceed 0xFFFF is meaningless. One might consider these checks as some sort of defensive coding, in case the type was later changed. However, these checks also byte-swap the value before comparison using be16_to_cpu, which will truncate the values to 16bits anyways. Additionally, changing the type would require updating the opcodes to support new data layout of these virtchnl commands. Remove the check to silence the -Wtype-limits warning that was added to GCC 8.
