Vladimir Oltean says: ==================== Convert NXP SJA1105 DSA driver to YAML This is an attempt to convert the SJA1105 driver to the YAML schema. The SJA1105 driver has some custom device tree properties which caused validation problems in the previous attempt: https://patchwork.kernel.org/project/netdevbpf/patch/20210531234735.1582031-1-olteanv@gmail.com/ So now we are removing them, hoping that this will make the conversion easier to accept. In order to do that, we introduce a new PHY interface type, "reverse RMII", which is like "reverse MII" (aka MII as a PHY) but for the reduced data width version of the protocol. This is a direct replacement for an rmii fixed-link. Now, rmii fixed-link interfaces behave as a MAC, and rev-rmii fixed-link interfaces behave as a PHY. ==================== Signed-off-by: David S.

2021-06-07net: dsa: sja1105: apply RGMII delays based on the fixed-link propertyVladimir Oltean
The sja1105 driver has an intermediate way of determining whether the RGMII delays should be applied by the PHY or by itself: by looking at the port role (PHY or MAC). The port can be put in the PHY role either explicitly (sja1105,role-phy) or implicitly (fixed-link). We want to deprecate the sja1105,role-phy property, so all that remains is the fixed-link property. Introduce a "fixed_link" array of booleans in the driver, and use that to determine whether RGMII delays must be applied or not.

2021-06-07net: phy: introduce PHY_INTERFACE_MODE_REVRMIIVladimir Oltean
The "reverse RMII" protocol name is a personal invention, derived from "reverse MII". Just like MII, RMII is an asymmetric protocol in that a PHY behaves differently than a MAC. In the case of RMII, for example: - the 50 MHz clock signals are either driven by the MAC or by an external oscillator (but never by the PHY). - the PHY can transmit extra in-band control symbols via RXD[1:0] which the MAC is supposed to understand, but a PHY isn't. The "reverse MII" protocol is not standardized either, except for this web document: https://www.eetimes.com/reverse-media-independent-interface-revmii-block-architecture/# In short, it means that the Ethernet controller speaks the 4-bit data parallel protocol from the perspective of a PHY (it acts like a PHY). This might mean that it implements clause 22 compatible registers, although that is optional - the important bit is that its pins can be connected to an MII MAC and it will 'just work'. In this discussion thread: https://lore.kernel.org/netdev/20210201214515.cx6ivvme2tlquge2@skbuf/ we agreed that it would be an abuse of terms to use the "RevMII" name for anything than the 4-bit parallel MII protocol. But since all the same concepts can be applied to the 2-bit Reduced MII protocol as well, here we are introducing a "Reverse RMII" protocol. This means: "behave like an RMII PHY".

2021-06-07ice: (re)initialize NVM fields when rebuildingJacob Keller
After performing a flash update, a device EMP reset may occur. This reset will cause the newly downloaded firmware to be initialized. When this happens, the driver still reports the previous NVM version information. This is because the NVM versions are cached within the hw structure. This can be confusing, as the new firmware is in fact running in this case. Handle this by calling ice_init_nvm when rebuilding the driver state. This will update the flash version information and ensures that the current values are displayed when reporting the NVM versions to the stack.

2021-06-07ice: wait for reset before reporting devlink infoJacob Keller
Requesting device firmware information while the device is busy cleaning up after a reset can result in an unexpected failure: This occurs because the command is attempting to access the device AdminQ while it is down. Resolve this by having the command wait for a while until the reset is complete. To do this, introduce a reset_wait_queue and associated helper function "ice_wait_for_reset". This helper will use the wait queue to sleep until the driver is done rebuilding. Use of a wait queue is preferred because the potential sleep duration can be several seconds. To ensure that the thread wakes up properly, a new wake_up call is added during all code paths which clear the reset state bits associated with the driver rebuild flow. Using this ensures that tools can request device information without worrying about whether the driver is cleaning up from a reset. Specifically, it is expected that a flash update could result in a device reset, and it is better to delay the response for information until the reset is complete rather than exit with an immediate failure.

2021-06-07ice: add error message when pldmfw_flash_image failsJacob Keller
When flashing a new firmware image onto the device, the pldmfw library parses the image contents looking for a matching record. If no record can be found, the function reports an error of -ENOENT. This can produce a very confusing error message and experience for the user: $devlink dev flash pci/0000:ab:00.0 file image.bin devlink answers: No such file or directory This is because the ENOENT error code is interpreted as a missing file or directory. The pldmfw library does not have direct access to the extack pointer as it is generic and non-netdevice specific. The only way that ENOENT is returned by the pldmfw library is when no record matches. Catch this specific error and report a suitable extended ack message: $devlink dev flash pci/0000:ab:00.0 file image.bin Error: ice: Firmware image has no record matching this device devlink answers: No such file or directory In addition, ensure that we log an error message to the console whenever this function fails. Because our driver specific PLDM operation functions potentially set the extended ACK message, avoid overwriting this with a generic message. This change should result in an improved experience when attempting to flash an image that does not have a compatible record.

2021-06-07ice: Refactor VIRTCHNL_OP_CONFIG_VSI_QUEUES handlingBrett Creeley
Currently, when a VF requests queue configuration via VIRTCHNL_OP_CONFIG_VSI_QUEUES the PF driver expects that this message will only be called once and we always assume the queues being configured start from 0. This is incorrect and is causing issues when a VF tries to send this message for multiple queue blocks. Fix this by using the queue_id specified in the virtchnl message and allowing for individual Rx and/or Tx queues to be configured. Also, reduce the duplicated for loops for configuring the queues by moving all the logic into a single for loop.

2021-06-07ice: Save VF's MAC across rebootBrett Creeley
If a VM reboots and/or VF driver is unloaded, its cached hardware MAC address (hw_lan_addr.addr) is cleared in some cases. If the VF is trusted, then the PF driver allows the VF to clear its old MAC address even if this MAC was configured by a host administrator. If the VF is untrusted, then the PF driver allows the VF to clear its old MAC address only if the host admin did not set it. For the trusted VF case, this is unexpected and will cause issues because the host configured MAC (i.e. via XML) will be cleared on VM reboot. For the untrusted VF case, this is done to be consistent and it will allow the VF to keep the same MAC across VM reboot. Fix this by introducing dev_lan_addr to the VF structure. This will be the VF's MAC address when it's up and running and in most cases will be the same as the hw_lan_addr. However, to address the VM reboot and unload/reload problem, the driver will never allow the hw_lan_addr to be cleared via VIRTCHNL_OP_DEL_ETH_ADDR. When the VF's MAC is changed, the dev_lan_addr and hw_lan_addr will always be updated with the same value. The only ways the VF's MAC can change are the following: - Set the VF's MAC administratively on the host via iproute2. - If the VF is trusted and changes/sets its own MAC. - If the VF is untrusted and the host has not set the MAC via iproute2.

2021-06-07ice: Manage VF's MAC address for both legacy and new casesBrett Creeley
Currently there is no way for a VF driver to specify if it wants to change it's hardware address. New bits are being added to virtchnl.h in struct virtchnl_ether_addr that allow for the VF to correctly communicate this information. However, legacy VF drivers that don't support the new virtchnl.h bits still need to be supported. Make a best effort attempt at saving the VF's primary/device address in the legacy case and depend on the VIRTCHNL_ETHER_ADDR_PRIMARY type for the new case. Legacy case - If a unicast MAC is being added and the hw_lan_addr.addr is empty, then populate it. This assumes that the address is the VF's hardware address. If a unicast MAC is being added and the hw_lan_addr.addr is not empty, then cache it in the legacy_last_added_umac.addr. If a unicast MAC is being deleted and it matches the hw_lan_addr.addr, then zero the hw_lan_addr.addr. Also, if the legacy_last_added_umac.addr has not expired, copy the legacy_last_added_umac.addr into the hw_lan_addr.addr. This is done because we cannot guarantee the order of VIRTCHNL_OP_ADD_ETH_ADDR and VIRTCHNL_OP_DEL_ETH_ADDR. New case - If a unicast MAC is being added and it's specified as VIRTCHNL_ETHER_ADDR_PRIMARY, then replace the current hw_lan_addr.addr. If a unicast MAC is being deleted and it's type is specified as VIRTCHNL_ETHER_ADDR_PRIMARY, then zero the hw_lan_addr.addr. Untrusted VFs - Only allow above legacy/new changes to their hardware address if the PF has not set it administratively via iproute2. Trusted VFs - Always allow above legacy/new changes to their hardware address even if the PF has administratively set it via iproute2. Also, change the variable dflt_lan_addr to hw_lan_addr to clearly represent the purpose of this variable since it's purpose is to act as a hardware programmed MAC address for the VF.

2021-06-07virtchnl: Use pad byte in virtchnl_ether_addr to specify MAC typeBrett Creeley
Currently, there is no way for a VF driver to specify that it wants to change its device/primary unicast MAC address. This makes it difficult/impossible for the PF driver to track the VF's device/primary unicast MAC address, which is used for VM/VF reboot and displaying on the host. Fix this by using 2 bits of a pad byte in the virtchnl_ether_addr structure so the VF can specify what type of MAC it's adding/deleting. Below are the values that should be used by all VF drivers going forward. VIRTCHNL_ETHER_ADDR_LEGACY(0): - The type should only ever be 0 for legacy AVF drivers (i.e. drivers that don't support the new type bits). The PF drivers will track VF's device/primary unicast MAC, but this will only be a best effort. VIRTCHNL_ETHER_ADDR_PRIMARY(1): - This type should only be used when the VF is changing their device/primary unicast MAC. It should be used for both delete and add cases related to the device/primary unicast MAC. VIRTCHNL_ETHER_ADDR_EXTRA(2): - This type should be used when the VF is adding and/or deleting MAC addresses that are not the device/primary unicast MAC. For example, extra unicast addresses and multicast addresses assuming the PF supports "extra" addresses at all. If a PF is parsing the type field of the virtchnl_ether_addr, then it should use the VIRTCHNL_ETHER_ADDR_TYPE_MASK to mask the first two bits of the type field since 0, 1, and 2 are the only valid values.

2021-06-07netfilter: flowtable: Set offload timeouts according to proto valuesOz Shlomo
Currently the aging period for tcp/udp connections is hard coded to 30 seconds. Aged tcp/udp connections configure a hard coded 120/30 seconds pickup timeout for conntrack. This configuration may be too aggressive or permissive for some users. Dynamically configure the nf flow table GC timeout intervals according to the user defined values.

2021-06-07netfilter: conntrack: Introduce udp offload timeout configurationOz Shlomo
UDP connections may be offloaded from nf conntrack to nf flow table. Offloaded connections are aged after 30 seconds of inactivity. Once aged, ownership is returned to conntrack with a hard coded pickup time of 30 seconds, after which the connection may be deleted. eted. The current aging intervals may be too aggressive for some users. Provide users with the ability to control the nf flow table offload aging and pickup time intervals via sysctl parameter as a pre-step for configuring the nf flow table GC timeout intervals.

2021-06-07netfilter: nf_tables: remove nft_ctx_init_from_setattr()Pablo Neira Ayuso
Replace nft_ctx_init_from_setattr() by nft_table_lookup(). This patch also disentangles nf_tables_delset() where NFTA_SET_TABLE is required while nft_ctx_init_from_setattr() allows it to be optional. From the nf_tables_delset() path, this also allows to set up the context structure when it is needed. Removing this helper function saves us 14 LoC, so it is not helping to consolidate code.

Replace nft_ctx_init_from_elemattr() by nft_table_lookup() and set up the context structure right before it is really needed. Moreover, nft_ctx_init_from_elemattr() is setting up the context structure for codepaths where this is not really needed at all. This helper function is also not helping to consolidate code, removing it saves us 4 LoC. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

Add an inbound policy filter which matches the HSR/PRP supervision MAC range and forwards to the CPU port without discarding duplicates. This is required to correctly populate time_in[A] and time_in[B] in the HSR/PRP node_table. Leave the policy disabled by default and enable/disable it when joining/leaving hsr.

2021-06-04cxgb4: avoid link re-train during TC-MQPRIO configurationRahul Lakkireddy
When configuring TC-MQPRIO offload, only turn off netdev carrier and don't bring physical link down in hardware. Otherwise, when the physical link is brought up again after configuration, it gets re-trained and stalls ongoing traffic. Also, when firmware is no longer accessible or crashed, avoid sending FLOWC and waiting for reply that will never come. Fix following hung_task_timeout_secs trace seen in these cases.
