Move common *_aq_desc structure to libie header and changing it in ice, ixgbe, i40e and iavf. Only generic adminq commands can be easily moved to common header, as rest is slightly different. Format remains the same. It will be better to correctly move it when it will be needed to commonize other part of the code. Move *_aq_str() to new libie module (libie_adminq) and use it across drivers. The functions are exactly the same in each driver. Some more adminq helpers/functions can be moved to libie_adminq when needed. * '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: i40e: use libie_aq_str iavf: use libie_aq_str ice: use libie_aq_str libie: add adminq helper for converting err to str iavf: use libie adminq descriptors i40e: use libie adminq descriptors ixgbe: use libie adminq descriptors ice, libie: move generic adminq descriptors to lib ==================== Link: https://patch.msgid.link/20250724182826.3758850-1-anthony.l.nguyen@intel.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2025-07-21i40e: When removing VF MAC filters, only check PF-set MACJamie Bainbridge1-2/+2
When the PF is processing an Admin Queue message to delete a VF's MACs from the MAC filter, we currently check if the PF set the MAC and if the VF is trusted. This results in undesirable behaviour, where if a trusted VF with a PF-set MAC sets itself down (which sends an AQ message to delete the VF's MAC filters) then the VF MAC is erased from the interface. This results in the VF losing its PF-set MAC which should not happen. There is no need to check for trust at all, because an untrusted VF cannot change its own MAC. The only check needed is whether the PF set the MAC. If the PF set the MAC, then don't erase the MAC on link-down. Resolve this by changing the deletion check only for PF-set MAC. (the out-of-tree driver has also intentionally removed the check for VF trust here with OOT driver version 2.26.8, this changes the Linux kernel driver behaviour and comment to match the OOT driver behaviour) Fixes: ea2a1cfc3b201 ("i40e: Fix VF MAC filter removal") Signed-off-by: Jamie Bainbridge <jamie.bainbridge@gmail.com> Reviewed-by: Simon Horman <horms@kernel.org> Tested-by: Rafal Romanowski <rafal.romanowski@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>
2025-07-21i40e: report VF tx_dropped with tx_errors instead of tx_discardsDennis Chen1-1/+1
Currently the tx_dropped field in VF stats is not updated correctly when reading stats from the PF. This is because it reads from i40e_eth_stats.tx_discards which seems to be unused for per VSI stats, as it is not updated by i40e_update_eth_stats() and the corresponding register, GLV_TDPC, is not implemented[1]. Use i40e_eth_stats.tx_errors instead, which is actually updated by i40e_update_eth_stats() by reading from GLV_TEPC. To test, create a VF and try to send bad packets through it: $ echo 1 > /sys/class/net/enp2s0f0/device/sriov_numvfs $ cat test.py from scapy.all import * vlan_pkt = Ether(dst="ff:ff:ff:ff:ff:ff") / Dot1Q(vlan=999) / IP(dst="192.168.0.1") / ICMP() ttl_pkt = IP(dst="8.8.8.8", ttl=0) / ICMP() print("Send packet with bad VLAN tag") sendp(vlan_pkt, iface="enp2s0f0v0") print("Send packet with TTL=0") sendp(ttl_pkt, iface="enp2s0f0v0") $ ip -s link show dev enp2s0f0 16: enp2s0f0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000 link/ether 3c:ec:ef:b7:e0:ac brd ff:ff:ff:ff:ff:ff RX: bytes packets errors dropped missed mcast 0 0 0 0 0 0 TX: bytes packets errors dropped carrier collsns 0 0 0 0 0 0 vf 0 link/ether e2:c6:fd:c1:1e:92 brd ff:ff:ff:ff:ff:ff, spoof checking on, link-state auto, trust off RX: bytes packets mcast bcast dropped 0 0 0 0 0 TX: bytes packets dropped 0 0 0 $ python test.py Send packet with bad VLAN tag .

2025-06-10i40e: retry VFLR handling if there is ongoing VF resetRobert Malz1-1/+4
When a VFLR interrupt is received during a VF reset initiated from a different source, the VFLR may be not fully handled. This can leave the VF in an undefined state. To address this, set the I40E_VFLR_EVENT_PENDING bit again during VFLR handling if the reset is not yet complete. This ensures the driver will properly complete the VF reset in such scenarios.

2025-06-09net: intel: move RSS packet classifier types to libieJacob Keller5-112/+84
The Intel i40e, iavf, and ice drivers all include a definition of the packet classifier filter types used to program RSS hash enable bits. For i40e, these bits are used for both the PF and VF to configure the PFQF_HENA and VFQF_HENA registers. For ice and iAVF, these bits are used to communicate the desired hash enable filter over virtchnl via its struct virtchnl_rss_hashena. The virtchnl.h header makes no mention of where the bit definitions reside. Maintaining a separate copy of these bits across three drivers is cumbersome. Move the definition to libie as a new pctype.h header file. Each driver can include this, and drop its own definition. The ice implementation also defined a ICE_AVF_FLOW_FIELD_INVALID, intending to use this to indicate when there were no hash enable bits set. This is confusing, since the enumeration is using bit positions. A value of 0 *should* indicate the first bit. Instead, rewrite the code that uses ICE_AVF_FLOW_FIELD_INVALID to just check if the avf_hash is zero. From context this should be clear that we're checking if none of the bits are set. The values are kept as bit positions instead of encoding the BIT_ULL directly into their value. While most users will simply use BIT_ULL immediately, i40e uses the macros both with BIT_ULL and test_bit/set_bit calls.

2025-06-09net: intel: rename 'hena' to 'hashcfg' for clarityJacob Keller3-27/+29
i40e, ice, and iAVF all use 'hena' as a shorthand for the "hash enable" configuration. This comes originally from the X710 datasheet 'xxQF_HENA' registers. In the context of the registers the meaning is fairly clear. However, on its own, hena is a weird name that can be more difficult to understand. This is especially true in ice. The E810 hardware doesn't even have registers with HENA in the name. Replace the shorthand 'hena' with 'hashcfg'. This makes it clear the variables deal with the Hash configuration, not just a single boolean on/off for all hashing. Do not update the register names. These come directly from the datasheet for X710 and X722, and it is more important that the names can be searched.

Implement "mdd-auto-reset-vf" priv-flag to handle Tx and Rx MDD events for VFs. This flag is also used in other network adapters like ICE. Usage: - "on" - The problematic VF will be automatically reset if a malformed descriptor is detected. - "off" - The problematic VF will be disabled. In cases where a VF sends malformed packets classified as malicious, it can cause the Tx queue to freeze, rendering it unusable for several minutes. When an MDD event occurs, this new implementation allows for a graceful VF reset to quickly restore operational state. Currently, VF queues are disabled if an MDD event occurs. This patch adds the ability to reset the VF if a Tx or Rx MDD event occurs. It also includes MDD event logging throttling to avoid dmesg pollution and unifies the format of Tx and Rx MDD messages. Note: Standard message rate limiting functions like dev_info_ratelimited() do not meet our requirements. Custom rate limiting is implemented, please see the code for details.

2024-11-16ndo_fdb_add: Add a parameter to report whether notification was sentPetr Machata1-1/+2
Currently when FDB entries are added to or deleted from a VXLAN netdevice, the VXLAN driver emits one notification, including the VXLAN-specific attributes. The core however always sends a notification as well, a generic one. Thus two notifications are unnecessarily sent for these operations. A similar situation comes up with bridge driver, which also emits notifications on its own: # ip link add name vx type vxlan id 1000 dstport 4789 # bridge monitor fdb & [1] 1981693 # bridge fdb add de:ad:be:ef:13:37 dev vx self dst 192.0.2.1 de:ad:be:ef:13:37 dev vx dst 192.0.2.1 self permanent de:ad:be:ef:13:37 dev vx self permanent In order to prevent this duplicity, add a paremeter to ndo_fdb_add, bool *notified. The flag is primed to false, and if the callee sends a notification on its own, it sets it to true, thus informing the core that it should not generate another notification.

2024-11-15i40e: Fix handling changed priv flagsPeter Große1-1/+1
After assembling the new private flags on a PF, the operation to determine the changed flags uses the wrong bitmaps. Instead of xor-ing orig_flags with new_flags, it uses the still unchanged pf->flags, thus changed_flags is always 0. Fix it by using the correct bitmaps. The issue was discovered while debugging why disabling source pruning stopped working with release 6.7. Although the new flags will be copied to pf->flags later on in that function, disabling source pruning requires a reset of the PF, which was skipped due to this bug. Disabling source pruning: $ sudo ethtool --set-priv-flags eno1 disable-source-pruning on $ sudo ethtool --show-priv-flags eno1 Private flags for eno1: MFP : off total-port-shutdown : off LinkPolling : off flow-director-atr : on veb-stats : off hw-atr-eviction : off link-down-on-close : off legacy-rx : off disable-source-pruning: on disable-fw-lldp : off rs-fec : off base-r-fec : off vf-vlan-pruning : off Regarding reproducing: I observed the issue with a rather complicated lab setup, where * two VLAN interfaces are created on eno1 * each with a different MAC address assigned * each moved into a separate namespace * both VLANs are bridged externally, so they form a single layer 2 network The external bridge is done via a channel emulator adding packet loss and delay and the application in the namespaces tries to send/receive traffic and measure the performance. Sender and receiver are separated by namespaces, yet the network card "sees its own traffic" send back to it. To make that work, source pruning has to be disabled.

2024-11-05i40e: fix race condition by adding filter's intermediate sync stateAleksandr Loktionov3-2/+12
Fix a race condition in the i40e driver that leads to MAC/VLAN filters becoming corrupted and leaking. Address the issue that occurs under heavy load when multiple threads are concurrently modifying MAC/VLAN filters by setting mac and port VLAN. 1. Thread T0 allocates a filter in i40e_add_filter() within i40e_ndo_set_vf_port_vlan(). 2. Thread T1 concurrently frees the filter in __i40e_del_filter() within i40e_ndo_set_vf_mac(). 3. Subsequently, i40e_service_task() calls i40e_sync_vsi_filters(), which refers to the already freed filter memory, causing corruption. Reproduction steps: 1. Spawn multiple VFs. 2. Apply a concurrent heavy load by running parallel operations to change MAC addresses on the VFs and change port VLANs on the host. 3. Observe errors in dmesg: "Error I40E_AQ_RC_ENOSPC adding RX filters on VF XX, please set promiscuous on manually for VF XX". Exact code for stable reproduction Intel can't open-source now. The fix involves implementing a new intermediate filter state, I40E_FILTER_NEW_SYNC, for the time when a filter is on a tmp_add_list. These filters cannot be deleted from the hash list directly but must be removed using the full process.

2024-10-09i40e: Fix macvlan leak by synchronizing access to mac_filter_hashAleksandr Loktionov2-0/+3
This patch addresses a macvlan leak issue in the i40e driver caused by concurrent access to vsi->mac_filter_hash. The leak occurs when multiple threads attempt to modify the mac_filter_hash simultaneously, leading to inconsistent state and potential memory leaks. To fix this, we now wrap the calls to i40e_del_mac_filter() and zeroing vf->default_lan_addr.addr with spin_lock/unlock_bh(&vsi->mac_filter_hash_lock), ensuring atomic operations and preventing concurrent access. Additionally, we add lockdep_assert_held(&vsi->mac_filter_hash_lock) in i40e_add_mac_filter() to help catch similar issues in the future. Reproduction steps: 1. Spawn VFs and configure port vlan on them. 2. Trigger concurrent macvlan operations (e.g., adding and deleting portvlan and/or mac filters). 3. Observe the potential memory leak and inconsistent state in the mac_filter_hash. This synchronization ensures the integrity of the mac_filter_hash and prevents the described leak.

2024-07-12i40e: fix: remove needless retries of NVM updateAleksandr Loktionov1-4/+0
Remove wrong EIO to EGAIN conversion and pass all errors as is. After commit 230f3d53a547 ("i40e: remove i40e_status"), which should only replace F/W specific error codes with Linux kernel generic, all EIO errors suddenly started to be converted into EAGAIN which leads nvmupdate to retry until it timeouts and sometimes fails after more than 20 minutes in the middle of NVM update, so NVM becomes corrupted. The bug affects users only at the time when they try to update NVM, and only F/W versions that generate errors while nvmupdate. For example, X710DA2 with 0x8000ECB7 F/W is affected, but there are probably more... Command for reproduction is just NVM update: ./nvmupdate64 In the log instead of: i40e_nvmupd_exec_aq err I40E_ERR_ADMIN_QUEUE_ERROR aq_err I40E_AQ_RC_ENOMEM) appears: i40e_nvmupd_exec_aq err -EIO aq_err I40E_AQ_RC_ENOMEM i40e: eeprom check failed (-5), Tx/Rx traffic disabled The problematic code did silently convert EIO into EAGAIN which forced nvmupdate to ignore EAGAIN error and retry the same operation until timeout. That's why NVM update takes 20+ minutes to finish with the fail in the end.
