2023-11-23i40e: Fix adding unsupported cloud filtersIvan Vecera1-7/+9
If a VF tries to add unsupported cloud filter through virtchnl then i40e_add_del_cloud_filter(_big_buf) returns -ENOTSUPP but this error code is stored in 'ret' instead of 'aq_ret' that is used as error code sent back to VF. In this scenario where one of the mentioned functions fails the value of 'aq_ret' is zero so the VF will incorrectly receive a 'success'. Use 'aq_ret' to store return value and remove 'ret' local variable. Additionally fix the issue when filter allocation fails, in this case no notification is sent back to the VF.

2023-11-23ice: restore timestamp configuration after device resetJacob Keller3-40/+51
The driver calls ice_ptp_cfg_timestamp() during ice_ptp_prepare_for_reset() to disable timestamping while the device is resetting. This operation destroys the user requested configuration. While the driver does call ice_ptp_cfg_timestamp in ice_rebuild() to restore some hardware settings after a reset, it unconditionally passes true or false, resulting in failure to restore previous user space configuration. This results in a device reset forcibly disabling timestamp configuration regardless of current user settings. This was not detected previously due to a quirk of the LinuxPTP ptp4l application. If ptp4l detects a missing timestamp, it enters a fault state and performs recovery logic which includes executing SIOCSHWTSTAMP again, restoring the now accidentally cleared configuration. Not every application does this, and for these applications, timestamps will mysteriously stop after a PF reset, without being restored until an application restart. Fix this by replacing ice_ptp_cfg_timestamp() with two new functions: 1) ice_ptp_disable_timestamp_mode() which unconditionally disables the timestamping logic in ice_ptp_prepare_for_reset() and ice_ptp_release() 2) ice_ptp_restore_timestamp_mode() which calls ice_ptp_restore_tx_interrupt() to restore Tx timestamping configuration, calls ice_set_rx_tstamp() to restore Rx timestamping configuration, and issues an immediate TSYN_TX interrupt to ensure that timestamps which may have occurred during the device reset get processed. Modify the ice_ptp_set_timestamp_mode to directly save the user configuration and then call ice_ptp_restore_timestamp_mode. This way, reset no longer destroys the saved user configuration. This obsoletes the ice_set_tx_tstamp() function which can now be safely removed. With this change, all devices should now restore Tx and Rx timestamping functionality correctly after a PF reset without application intervention.

2023-11-23ice: unify logic for programming PFINT_TSYN_MSKJacob Keller1-26/+34
Commit d938a8cca88a ("ice: Auxbus devices & driver for E822 TS") modified how Tx timestamps are handled for E822 devices. On these devices, only the clock owner handles reading the Tx timestamp data from firmware. To do this, the PFINT_TSYN_MSK register is modified from the default value to one which enables reacting to a Tx timestamp on all PHY ports. The driver currently programs PFINT_TSYN_MSK in different places depending on whether the port is the clock owner or not. For the clock owner, the PFINT_TSYN_MSK value is programmed during ice_ptp_init_owner just before calling ice_ptp_tx_ena_intr to program the PHY ports. For the non-clock owner ports, the PFINT_TSYN_MSK is programmed during ice_ptp_init_port. If a large enough device reset occurs, the PFINT_TSYN_MSK register will be reset to the default value in which only the PHY associated directly with the PF will cause the Tx timestamp interrupt to trigger. The driver lacks logic to reprogram the PFINT_TSYN_MSK register after a device reset. For the E822 device, this results in the PF no longer responding to interrupts for other ports. This results in failure to deliver Tx timestamps to user space applications. Rename ice_ptp_configure_tx_tstamp to ice_ptp_cfg_tx_interrupt, and unify the logic for programming PFINT_TSYN_MSK and PFINT_OICR_ENA into one place. This function will program both registers according to the combination of user configuration and device requirements. This ensures that PFINT_TSYN_MSK is always restored when we configure the Tx timestamp interrupt.

2023-11-23ice: remove ptp_tx ring parameter flagJacob Keller3-18/+0
Before performing a Tx timestamp in ice_stamp(), the driver checks a ptp_tx ring variable to see if timestamping is enabled on that ring. This value is set for all rings whenever userspace configures Tx timestamping. Ostensibly this was done to avoid wasting cycles checking other fields when timestamping has not been enabled. However, for Tx timestamps we already get an individual per-SKB flag indicating whether userspace wants to request a timestamp on that packet. We do not gain much by also having a separate flag to check for whether timestamping was enabled. In fact, the driver currently fails to restore the field after a PF reset. Because of this, if a PF reset occurs, timestamps will be disabled. Since this flag doesn't add value in the hotpath, remove it and always provide a timestamp if the SKB flag has been set. A following change will fix the reset path to properly restore user timestamping configuration completely. This went unnoticed for some time because one of the most common applications using Tx timestamps, ptp4l, will reconfigure the socket as part of its fault recovery logic.

2023-11-23octeontx2-pf: Fix ntuple rule creation to direct packet to VF with higher Rx ↵Suman Ghosh1-1/+19
queue than its PF It is possible to add a ntuple rule which would like to direct packet to a VF whose number of queues are greater/less than its PF's queue numbers. For example a PF can have 2 Rx queues but a VF created on that PF can have 8 Rx queues. As of today, ntuple rule will reject rule because it is checking the requested queue number against PF's number of Rx queues. As a part of this fix if the action of a ntuple rule is to move a packet to a VF's queue then the check is removed. Also, a debug information is printed to aware user that it is user's responsibility to cross check if the requested queue number on that VF is a valid one.

2023-11-22Revert "net: r8169: Disable multicast filter for RTL8168H and RTL8107E"Heiner Kallweit1-3/+1
This reverts commit efa5f1311c4998e9e6317c52bc5ee93b3a0f36df. I couldn't reproduce the reported issue. What I did, based on a pcap packet log provided by the reporter: - Used same chip version (RTL8168h) - Set MAC address to the one used on the reporters system - Replayed the EAPOL unicast packet that, according to the reporter, was filtered out by the mc filter. The packet was properly received. Therefore the root cause of the reported issue seems to be somewhere else. Disabling mc filtering completely for the most common chip version is a quite big hammer. Therefore revert the change and wait for further analysis results from the reporter. Cc: stable@vger.kernel.org Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.

Follow up to the previous patch to fix the same issue for mlx5e_tc_tun_update_header_ipv4{6} when mlx5_packet_reformat_alloc() fails. When mlx5_packet_reformat_alloc() fails, the encap_header allocated in mlx5e_tc_tun_update_header_ipv4{6} will be released within it. However, e->encap_header is already set to the previously freed encap_header before mlx5_packet_reformat_alloc(). As a result, the later mlx5e_encap_put() will free e->encap_header again, causing a double free issue. mlx5e_encap_put() --> mlx5e_encap_dealloc() --> kfree(e->encap_header) This patch fix it by not setting e->encap_header until mlx5_packet_reformat_alloc() success.

2023-11-16net/mlx5: Free used cpus mask when an IRQ is releasedMaher Sanalla2-48/+19
Each EQ table maintains a cpumask of the already used CPUs that are mapped to IRQs to ensure that each IRQ gets mapped to a unique CPU. However, on IRQ release, the said cpumask is not updated by clearing the CPU from the mask to allow future IRQ request, causing the following error when a SF is reloaded after it has utilized all CPUs for its IRQs: mlx5_irq_affinity_request:135:(pid 306010): Didn't find a matching IRQ. err = -28 Thus, when releasing an IRQ, clear its mapped CPU from the used CPUs mask, to prevent the case described above. While at it, move the used cpumask update to the EQ layer as it is more fitting and preserves symmetricity of the IRQ request/release API.

Leave one descriptor unused to avoid wrap around of 'dirty_rx' vs 'cur_rx'.

The while loop condition verifies 'count < limit'. Neither value change before the 'count >= limit' check. As is this check is dead code. But code inspection reveals a code path that modifies 'count' and then goto 'drain_data' and back to 'read_again'. So there is a need to verify count value sanity after 'read_again'. Move 'read_again' up to fix the count limit check.

2023-11-14net: ethernet: cortina: Fix MTU max settingLinus Walleij2-14/+5
The RX max frame size is over 10000 for the Gemini ethernet, but the TX max frame size is actually just 2047 (0x7ff after checking the datasheet). Reflect this in what we offer to Linux, cap the MTU at the TX max frame minus ethernet headers. We delete the code disabling the hardware checksum for large MTUs as netdev->mtu can no longer be larger than netdev->max_mtu meaning the if()-clause in gmac_fix_features() is never true.

2023-11-14net: ethernet: cortina: Handle large framesLinus Walleij1-1/+23
The Gemini ethernet controller provides hardware checksumming for frames up to 1514 bytes including ethernet headers but not FCS. If we start sending bigger frames (after first bumping up the MTU on both interfaces sending and receiving the frames), truncated packets start to appear on the target such as in this tcpdump resulting from ping -s 1474: 23:34:17.241983 14:d6:4d:a8:3c:4f (oui Unknown) > bc:ae:c5:6b:a8:3d (oui Unknown), ethertype IPv4 (0x0800), length 1514: truncated-ip - 2 bytes missing! (tos 0x0, ttl 64, id 32653, offset 0, flags [DF], proto ICMP (1), length 1502) OpenWrt.lan > Fecusia: ICMP echo request, id 1672, seq 50, length 1482 If we bypass the hardware checksumming and provide a software fallback, everything starts working fine up to the max TX MTU of 2047 bytes, for example ping -s2000 192.168.1.2: 00:44:29.587598 bc:ae:c5:6b:a8:3d (oui Unknown) > 14:d6:4d:a8:3c:4f (oui Unknown), ethertype IPv4 (0x0800), length 2042: (tos 0x0, ttl 64, id 51828, offset 0, flags [none], proto ICMP (1), length 2028) Fecusia > OpenWrt.lan: ICMP echo reply, id 1683, seq 4, length 2008 The bit enabling to bypass hardware checksum (or any of the "TSS" bits) are undocumented in the hardware reference manual. The entire hardware checksum unit appears undocumented. The conclusion that we need to use the "bypass" bit was found by trial-and-error. Since no hardware checksum will happen, we slot in a software checksum fallback. Check for the condition where we need to compute checksum on the skb with either hardware or software using == CHECKSUM_PARTIAL instead of != CHECKSUM_NONE which is an incomplete check according to <linux/skbuff.h>. On the D-Link DIR-685 router this fixes a bug on the conduit interface to the RTL8366RB DSA switch: as the switch needs to add space for its tag it increases the MTU on the conduit interface to 1504 and that means that when the router sends packages of 1500 bytes these get an extra 4 bytes of DSA tag and the transfer fails because of the erroneous hardware checksumming, affecting such basic functionality as the LuCI web interface.

If PF is down, firmware will returns 10 Mbit/s rate and half-duplex mode when PF queries the port information from firmware. After imp reset command is executed, PF status changes to down, and PF will query link status and updates port information from firmware in a periodic scheduled task. However, there is a low probability that port information is updated when PF is down, and then PF link status changes to up. In this case, PF synchronizes incorrect rate and duplex mode to VF.
