Henry corrects setting an unspecified protocol to IPPROTO_NONE instead of 0 for IPv6 flexbytes filters for ice. Nick fixes the IPv6 extension header being processed incorrectly and updates the netdev->dev_addr if it exists in hardware as it may have been modified outside the ice driver. Brett ensures a user cannot request more channels than available LAN MSI-X and fixes the minimum allocation logic as it was incorrectly trying to use more MSI-X than allocated for ice.

On building the route there is an assumption that the destination could be local. In this case loopback_dev is used to get the address. If the address is still cannot be retrieved dn_route_output_slow returns EADDRNOTAVAIL with loopback_dev reference taken. Cannot find hash for the fixes tag because this code was introduced long time ago. I don't think that this bug has ever fired but the patch is done just to have a consistent code base. Signed-off-by:

It's not true that switchdev_port_obj_notify() only inspects the ->handled field of "struct switchdev_notifier_port_obj_info" if call_switchdev_blocking_notifiers() returns 0 - there's a WARN_ON() triggering for a non-zero return combined with ->handled not being true. But the real problem here is that -EOPNOTSUPP is not being properly handled. The wrapper functions switchdev_handle_port_obj_add() et al change a return value of -EOPNOTSUPP to 0, and the treatment of ->handled in switchdev_port_obj_notify() seems to be designed to change that back to -EOPNOTSUPP in case nobody actually acted on the notifier (i.e., everybody returned -EOPNOTSUPP). Currently, as soon as some device down the stack passes the check_cb() check, ->handled gets set to true, which means that switchdev_port_obj_notify() cannot actually ever return -EOPNOTSUPP. This, for example, means that the detection of hardware offload support in the MRP code is broken: switchdev_port_obj_add() used by br_mrp_switchdev_send_ring_test() always returns 0, so since the MRP code thinks the generation of MRP test frames has been offloaded, no such frames are actually put on the wire. Similarly, br_mrp_switchdev_set_ring_role() also always returns 0, causing mrp->ring_role_offloaded to be set to 1. To fix this, continue to set ->handled true if any callback returns success or any error distinct from -EOPNOTSUPP. But if all the callbacks return -EOPNOTSUPP, make sure that ->handled stays false, so the logic in switchdev_port_obj_notify() can propagate that information. Fixes: 9a9f26e8 ("bridge: mrp: Connect MRP API with the switchdev API") Fixes: f30f0601 ("switchdev: Add helpers to aid traversal through lower devices") Reviewed-by:

Laurent Badel says: ==================== net: fec: Fix temporary RMII clock reset on link up v2: fixed a compilation warning The FEC drivers performs a "hardware reset" of the MAC module when the link is reported to be up. This causes a short glitch in the RMII clock due to the hardware reset clearing the receive control register which controls the MII mode. It seems that some link partners do not tolerate this glitch, and invalidate the link, which leads to a never-ending loop of negotiation-link up-link down events. This was observed with the iMX28 Soc and LAN8720/LAN8742 PHYs, with two Intel adapters I218-LM and X722-DA2 as link partners, though a number of other link partners do not seem to mind the clock glitch. Changing the hardware reset to a software reset (clearing bit 1 of the ECR register) cured the issue. Attempts to optimize fec_restart() in order to minimize the duration of the glitch were unsuccessful. Furthermore manually producing the glitch by setting MII mode and then back to RMII in two consecutive instructions, resulting in a clock glitch <10us in duration, was enough to cause the partner to invalidate the link. This strongly suggests that the root cause of the link being dropped is indeed the change in clock frequency. In an effort to minimize changes to driver, the patch proposes to use soft reset only for tested SoCs (iMX28) and only if the link is up. This preserves hardware reset in other situations, which might be required for proper setup of the MAC. ==================== Link: https://lore.kernel.org/r/20210125100745.5090-1-laurentbadel@eaton.comSigned-off-by:

fec_restart() does a hard reset of the MAC module when the link status changes to up. This temporarily resets the R_CNTRL register which controls the MII mode of the ENET_OUT clock. In the case of RMII, the clock frequency momentarily drops from 50MHz to 25MHz until the register is reconfigured. Some link partners do not tolerate this glitch and invalidate the link causing failure to establish a stable link when using PHY polling mode. Since as per IEEE802.3 the criteria for link validity are PHY-specific, what the partner should tolerate cannot be assumed, so avoid resetting the MII clock by using software reset instead of hardware reset when the link is up. This is generally relevant only if the SoC provides the clock to an external PHY and the PHY is configured for RMII. Signed-off-by:

In the lapb module, the timers may run concurrently with other code in this module, and there is currently no locking to prevent the code from racing on "struct lapb_cb". This patch adds locking to prevent racing. 1. Add "spinlock_t lock" to "struct lapb_cb"; Add "spin_lock_bh" and "spin_unlock_bh" to APIs, timer functions and notifier functions. 2. Add "bool t1timer_stop, t2timer_stop" to "struct lapb_cb" to make us able to ask running timers to abort; Modify "lapb_stop_t1timer" and "lapb_stop_t2timer" to make them able to abort running timers; Modify "lapb_t2timer_expiry" and "lapb_t1timer_expiry" to make them abort after they are stopped by "lapb_stop_t1timer", "lapb_stop_t2timer", and "lapb_start_t1timer", "lapb_start_t2timer". 3. Let lapb_unregister wait for other API functions and running timers to stop. 4. The lapb_device_event function calls lapb_disconnect_request. In order to avoid trying to hold the lock twice, add a new function named "__lapb_disconnect_request" which assumes the lock is held, and make it called by lapb_disconnect_request and lapb_device_event.

Function __team_compute_features() is protected by team->lock mutex when it is called from team_compute_features() used when features of an underlying device is changed. This causes a deadlock when NETDEV_FEAT_CHANGE notifier for underlying device is fired due to change propagated from team driver (e.g. MTU change). It's because callbacks like team_change_mtu() or team_vlan_rx_{add,del}_vid() protect their port list traversal by team->lock mutex. Example (r8169 case where this driver disables TSO for certain MTU values): ... [ 6391.348202] __mutex_lock.isra.6+0x2d0/0x4a0 [ 6391.358602] team_device_event+0x9d/0x160 [team] [ 6391.363756] notifier_call_chain+0x47/0x70 [ 6391.368329] netdev_update_features+0x56/0x60 [ 6391.373207] rtl8169_change_mtu+0x14/0x50 [r8169] [ 6391.378457] dev_set_mtu_ext+0xe1/0x1d0 [ 6391.387022] dev_set_mtu+0x52/0x90 [ 6391.390820] team_change_mtu+0x64/0xf0 [team] [ 6391.395683] dev_set_mtu_ext+0xe1/0x1d0 [ 6391.399963] do_setlink+0x231/0xf50 ...

Sometimes, channel params are changed without recreating the channels. It happens in two basic cases: when the channels are closed, and when the parameter being changed doesn't affect how channels are configured. Such changes invoke a hardware command that might fail.

Currently, if a neighbour isn't valid when offloading tunnel encap rules, we offload the original match and replace the original action with "goto slow path" action. For this we use a temporary flow attribute based on the original flow attribute and then change the action. Flow flags, which among those is the CT flag, are still shared for the slow path rule offload, so we end up parsing this flow as a CT + goto slow path rule. Besides being unnecessary, CT action offload saves extra information in the passed flow attribute, such as created ct_flow and mod_hdr, which is lost onces the temporary flow attribute is freed. When a neigh is updated and is valid, we offload the original CT rule with original CT action, which again creates a ct_flow and mod_hdr and saves it in the flow's original attribute. Then we delete the slow path rule with a temporary flow attribute based on original updated flow attribute, and we free the relevant ct_flow and mod_hdr. Then when tc deletes this flow, we try to free the ct_flow and mod_hdr on the flow's attribute again. To fix the issue, skip all furture proccesing (CT/Sample/Split rules) in offload/unoffload of slow path rules.

Link speed advertising in igc has two problems: - When setting the advertisement via ethtool, the link speed is converted to the legacy 32 bit representation for the intel PHY code. This inadvertently drops ETHTOOL_LINK_MODE_2500baseT_Full_BIT (being beyond bit 31). As a result, any call to `ethtool -s ...' drops the 2500Mbit/s link speed from the PHY settings. Only reloading the driver alleviates that problem. Fix this by converting the ETHTOOL_LINK_MODE_2500baseT_Full_BIT to the Intel PHY ADVERTISE_2500_FULL bit explicitly. - Rather than checking the actual PHY setting, the .get_link_ksettings function always fills link_modes.advertising with all link speeds the device is capable of. Fix this by checking the PHY autoneg_advertised settings and report only the actually advertised speeds up to ethtool. Fixes: 8c5ad0da ("igc: Add ethtool support") Signed-off-by:

The current MSI-X enablement logic tries to enable best-case MSI-X vectors and if that fails we only support a bare-minimum set. This includes a single MSI-X for 1 Tx and 1 Rx queue and a single MSI-X for the OICR interrupt. Unfortunately, the driver fails to load when we don't get as many MSI-X as requested for a couple reasons. First, the code to allocate MSI-X in the driver tries to allocate num_online_cpus() MSI-X for LAN traffic without caring about the number of MSI-X actually enabled/requested from the kernel for LAN traffic. So, when calling ice_get_res() for the PF VSI, it returns failure because the number of available vectors is less than requested. Fix this by not allowing the PF VSI to allocation more than pf->num_lan_msix MSI-X vectors and pf->num_lan_msix Rx/Tx queues. Limiting the number of queues is done because we don't want more than 1 Tx/Rx queue per interrupt due to performance conerns. Second, the driver assigns pf->num_lan_msix = 2, to account for LAN traffic and the OICR. However, pf->num_lan_msix is only meant for LAN MSI-X. This is causing a failure when the PF VSI tries to allocate/reserve the minimum pf->num_lan_msix because the OICR MSI-X has already been reserved, so there may not be enough MSI-X vectors left. Fix this by setting pf->num_lan_msix = 1 for the failure case. Then the ICE_MIN_MSIX accounts for the LAN MSI-X and the OICR MSI-X needed for the failure case. Update the related defines used in ice_ena_msix_range() to align with the above behavior and remove the unused RDMA defines because RDMA is currently not supported. Also, remove the now incorrect comment. Fixes: 152b978a ("ice: Rework ice_ena_msix_range") Signed-off-by:

This patch is based on a similar change to i40e by Slawomir Laba: "i40e: Implement flow for IPv6 next header (extension header)". When a packet contains an IPv6 header with next header which is an extension header and not a protocol one, the kernel function skb_transport_header called with such sk_buff will return a pointer to the extension header and not to the TCP one. The above explained call caused a problem with packet processing for skb with encapsulation for tunnel with ICE_TX_CTX_EIPT_IPV6. The extension header was not skipped at all. The ipv6_skip_exthdr function does check if next header of the IPV6 header is an extension header and doesn't modify the l4_proto pointer if it points to a protocol header value so its safe to omit the comparison of exthdr and l4.hdr pointers. The ipv6_skip_exthdr can return value -1. This means that the skipping process failed and there is something wrong with the packet so it will be dropped.
