2021-04-16igb: Add double-check MTA_REGISTER for i210 and i211Grzegorz Siwik
Add new function which checks MTA_REGISTER if its filled correctly. If not then writes again to same register. There is possibility that i210 and i211 could not accept MTA_REGISTER settings, specially when you add and remove many of multicast addresses in short time. Without this patch there is possibility that multicast settings will be not always set correctly in hardware.

2021-04-16net/mlx5e: Add ethtool extended link stateMoshe Tal
In case the interface was set up but cannot establish the link, ethtool will print more information to help the user troubleshoot the state. For example, no link due to missing cable: $ ethtool eth1 ... Link detected: no (No cable) Beside the general extended state, drivers can pass additional information about the link state using the sub-state field. For example: $ ethtool eth1 ... Link detected: no (Autoneg, No partner detected) The extended state is available only for specific cases, in other cases ethtool with print only "Link detected: no" as before Signed-off-by: Moshe Tal <moshet@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>

2021-04-16net/mlx5e: Cleanup safe switch channels API by passing paramsMaxim Mikityanskiy
mlx5e_safe_switch_channels accepts new_chs as a parameter and opens new channels in place, then copying them to priv->channels. It requires all the callers to allocate space for this temporary storage of the new channels. This commit cleans up the API by replacing new_chs with new_params, a meaningful subset of new_chs to be filled by the caller. The temporary space for the new channels is allocated inside mlx5e_safe_switch_params (a new name for mlx5e_safe_switch_channels). An extra copy of params is made, but since it's control flow, it's not critical. Signed-off-by: Maxim Mikityanskiy <maximmi@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>
2021-04-16net/mlx5e: Refactor on-the-fly configuration changesMaxim Mikityanskiy
This commit extends mlx5e_safe_switch_channels() to support on-the-fly configuration changes, when the channels are open, but don't need to be recreated. Such flows exist when a parameter being changed doesn't affect how the queues are created, or when the queues can be modified while remaining active. Before this commit, such flows were handled as special cases on the caller site. This commit adds this functionality to mlx5e_safe_switch_channels(), allowing the caller to pass a boolean indicating whether it's required to recreate the channels or it's allowed to skip it. The logic of switching channel parameters is now completely encapsulated into mlx5e_safe_switch_channels().

2021-04-16net/mlx5e: Use mlx5e_safe_switch_channels when channels are closedMaxim Mikityanskiy
This commit uses new functionality of mlx5e_safe_switch_channels introduced by the previous commit to reduce the amount of repeating similar code all over the driver. It's very common in mlx5e to call mlx5e_safe_switch_channels when the channels are open, but assign parameters and run hardware commands manually when the channels are closed. After the previous commit it's no longer needed to do such manual things every time, so this commit removes unneeded code and relies on the new functionality of mlx5e_safe_switch_channels. Some of the places are refactored and simplified, where more complex flows are used to change configuration on the fly, without recreating the channels (the logic is rewritten in a more robust way, with a reset required by default and a list of exceptions).

2021-04-16net/mlx5e: Allow mlx5e_safe_switch_channels to work with channels closedMaxim Mikityanskiy
mlx5e_safe_switch_channels is used to modify channel parameters and/or hardware configuration in a safe way, so that if anything goes wrong, everything reverts to the old configuration and remains in a consistent state. However, this function only works when the channels are open. When the caller needs to modify some parameters, first it has to check that the channels are open, otherwise it has to assign parameters directly, and such boilerplate repeats in many different places. This commit prepares for the refactoring of such places by allowing mlx5e_safe_switch_channels to work when the channels are closed. In this case it will assign the new parameters and run the preactivate hook. Signed-off-by: Maxim Mikityanskiy <maximmi@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>
2021-04-16net/mlx5e: kTLS, Add resiliency to RX resync failuresTariq Toukan
When the TLS logic finds a tcp seq match for a kTLS RX resync request, it calls the driver callback function mlx5e_ktls_resync() to handle it and communicate it to the device. Errors might occur during mlx5e_ktls_resync(), however, they are not reported to the stack. Moreover, there is no error handling in the stack for these errors. In this patch, the driver obtains responsibility on errors handling, adding queue and retry mechanisms to these resyncs. We maintain a linked list of resync matches, and try posting them to the async ICOSQ in the NAPI context. Only possible failure that demands driver handling is ICOSQ being full. By relying on the NAPI mechanism, we make sure that the entries in list will be handled when ICOSQ completions arrive and make some room available.

2021-04-16igb: Redistribute memory for transmit packet buffers when in Qav modeEderson de Souza
i210 has a total of 24KB of transmit packet buffer. When in Qav mode, this buffer is divided into four pieces, one for each Tx queue. Currently, 8KB are given to each of the two SR queues and 4KB are given to each of the two SP queues. However, it was noticed that such distribution can make best effort traffic (which would usually go to the SP queues when Qav is enabled, as the SR queues would be used by ETF or CBS qdiscs for TSN-aware traffic) perform poorly. Using iperf3 to measure, one could see the performance of best effort traffic drop by nearly a third (from 935Mbps to 578Mbps), with no TSN traffic competing. This patch redistributes the 24KB to each queue equally: 6KB each. On tests, there was no notable performance reduction of best effort traffic performance when there was no TSN traffic competing. Below, more details about the data collected: All experiments were run using the following qdisc setup: qdisc taprio 100: root refcnt 9 tc 4 map 3 3 3 2 3 0 0 3 3 3 3 3 3 3 3 3 queues offset 0 count 1 offset 1 count 1 offset 2 count 1 offset 3 count 1 clockid TAI base-time 0 cycle-time 10000000 cycle-time-extension 0 index 0 cmd S gatemask 0xf interval 10000000 qdisc etf 8045: parent 100:1 clockid TAI delta 1000000 offload on deadline_mode off skip_sock_check off TSN traffic, when enabled, had this characteristics: Packet size: 1500 bytes Transmission interval: 125us ---------------------------------- Without this patch: ---------------------------------- - TCP data: - No TSN traffic: [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-20.00 sec 1.35 GBytes 578 Mbits/sec 0 - With TSN traffic: [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-20.00 sec 1.07 GBytes 460 Mbits/sec 1 - TCP data limiting iperf3 buffer size to 4K: - No TSN traffic: [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-20.00 sec 1.35 GBytes 579 Mbits/sec 0 - With TSN traffic: [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-20.00 sec 1.08 GBytes 462 Mbits/sec 0 - TCP data limiting iperf3 buffer size to 192 bytes (smallest size without serious performance degradation): - No TSN traffic: [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-20.00 sec 1.34 GBytes 577 Mbits/sec 0 - With TSN traffic: [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-20.00 sec 1.07 GBytes 461 Mbits/sec 1 - UDP data at 1000Mbit/sec: - No TSN traffic: [ ID] Interval Transfer Bitrate Jitter Lost/Total Datagrams [ 5] 0.00-20.00 sec 1.36 GBytes 586 Mbits/sec 0.000 ms 0/1011407 (0%) - With TSN traffic: [ ID] Interval Transfer Bitrate Jitter Lost/Total Datagrams [ 5] 0.00-20.00 sec 1.05 GBytes 451 Mbits/sec 0.000 ms 0/778672 (0%) ---------------------------------- With this patch: ---------------------------------- - TCP data: - No TSN traffic: [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-20.00 sec 2.17 GBytes 932 Mbits/sec 0 - With TSN traffic: [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-20.00 sec 1.50 GBytes 646 Mbits/sec 1 - TCP data limiting iperf3 buffer size to 4K: - No TSN traffic: [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-20.00 sec 2.17 GBytes 931 Mbits/sec 0 - With TSN traffic: [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-20.00 sec 1.50 GBytes 645 Mbits/sec 0 - TCP data limiting iperf3 buffer size to 192 bytes (smallest size without serious performance degradation): - No TSN traffic: [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-20.00 sec 2.17 GBytes 932 Mbits/sec 1 - With TSN traffic: [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-20.00 sec 1.50 GBytes 645 Mbits/sec 0 - UDP data at 1000Mbit/sec: - No TSN traffic: [ ID] Interval Transfer Bitrate Jitter Lost/Total Datagrams [ 5] 0.00-20.00 sec 2.23 GBytes 956 Mbits/sec 0.000 ms 0/1650226 (0%) - With TSN traffic: [ ID] Interval Transfer Bitrate Jitter Lost/Total Datagrams [ 5] 0.00-20.00 sec 1.51 GBytes 649 Mbits/sec 0.000 ms 0/1120264 (0%) Signed-off-by: Ederson de Souza <ederson.desouza@intel.com> Tested-by: Tony Brelinski <tonyx.brelinski@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>

2021-04-15cxl/mem: Fix register block offset calculationBen Widawsky
The "Register Offset Low" register of a "DVSEC Register Locator" contains the 64K aligned offset for the registers along with the BAR indicator and an id. The implementation was treating the "Register Block Offset Low" field a value rather than as a pre-aligned component of the 64-bit offset. So, just mask, don't mask and shift (FIELD_GET). The user visible result of this bug is that the driver fails to bind to the device after none of the required blocks are found. This was missed earlier because the primary development done in the QEMU environment only uses 0 offsets, i.e. 0 shifted is still 0.

Similarly to pause statistics add stats for FEC. The IEEE standard mandates two sets of counters: - 30.5.1.1.17 aFECCorrectedBlocks - 30.5.1.1.18 aFECUncorrectableBlocks where block is a block of bits FEC operates on. Each of these counters is defined per lane (PCS instance). Multiple vendors provide number of corrected _bits_ rather than/as well as blocks. This set adds the 2 standard-based block counters and a extra one for corrected bits. Counters are exposed to user space via netlink in new attributes. Each attribute carries an array of u64s, first element is the total count, and the following ones are a per-lane break down. Much like with pause stats the operation will not fail when driver does not implement the get_fec_stats callback (nor can the driver fail the operation by returning an error).

2021-04-15net: hns3: PF add support for pushing link status to VFsGuangbin Huang
Previously, VF updates its link status every second by send query command to PF in periodic service task. If link stats of PF is changed, VF may need at most one second to update its link status. To reduce delay of link status between PF and VFs, PF actively push its link status to VFs when its link status is updated. And to let VF know PF supports this new feature, the link status changed mailbox command adds one bit to indicate it.

2021-04-15net: phy: at803x: select correct page on config initDavid Bauer
The Atheros AR8031 and AR8033 expose different registers for SGMII/Fiber as well as the copper side of the PHY depending on the BT_BX_REG_SEL bit in the chip configure register. The driver assumes the copper side is selected on probe, but this might not be the case depending which page was last selected by the bootloader. Notably, Ubiquiti UniFi bootloaders show this behavior. Select the copper page when probing to circumvent this. Signed-off-by: David Bauer <mail@david-bauer.net> Signed-off-by: David S.

git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue Tony Nguyen says: ==================== 100GbE Intel Wired LAN Driver Updates 2021-04-14 This series contains updates to ice driver only. Bruce changes and removes open coded values to instead use existing kernel defines and suppresses false cppcheck issues. Ani adds new VSI states to track netdev allocation and registration. He also removes leading underscores in the ice_pf_state enum. Jesse refactors ITR by introducing helpers to reduce duplicated code and structures to simplify checking of ITR mode. He also triggers a software interrupt when exiting napi poll or busy-poll to ensure all work is processed. Modifies /proc/iomem to display driver name instead of PCI address. He also changes the checks of vsi->type to use a local variable in ice_vsi_rebuild() and removes an unneeded struct member. Jake replaces the driver's adaptive interrupt moderation algorithm to use the kernel's DIM library implementation. Scott reworks module reads to reduce the number of reads needed and remove excessive increment of QSFP page. Brett sets the vsi->vf_id to invalid for non-VF VSIs. Paul removes the return value from ice_vsi_manage_rss_lut() as it's not communicating anything critical. He also reduces the scope of a variable. ==================== Signed-off-by: David S.

2021-04-15i40e: fix the panic when running bpf in xdpdrv modeJason Xing
Fix this panic by adding more rules to calculate the value of @rss_size_max which could be used in allocating the queues when bpf is loaded, which, however, could cause the failure and then trigger the NULL pointer of vsi->rx_rings. Prio to this fix, the machine doesn't care about how many cpus are online and then allocates 256 queues on the machine with 32 cpus online actually. Once the load of bpf begins, the log will go like this "failed to get tracking for 256 queues for VSI 0 err -12" and this "setup of MAIN VSI failed". Thus, I attach the key information of the crash-log here.

2021-04-15arm64: alternatives: Move length validation in alternative_{insn, endif}Nathan Chancellor
After commit 2decad92f473 ("arm64: mte: Ensure TIF_MTE_ASYNC_FAULT is set atomically"), LLVM's integrated assembler fails to build entry.S: <instantiation>:5:7: error: expected assembly-time absolute expression .org . - (664b-663b) + (662b-661b) ^ <instantiation>:6:7: error: expected assembly-time absolute expression .org . - (662b-661b) + (664b-663b) ^ The root cause is LLVM's assembler has a one-pass design, meaning it cannot figure out these instruction lengths when the .org directive is outside of the subsection that they are in, which was changed by the .arch_extension directive added in the above commit. Apply the same fix from commit 966a0acce2fc ("arm64/alternatives: move length validation inside the subsection") to the alternative_endif macro, shuffling the .org directives so that the length validation happen will always happen in the same subsections. alternative_insn has not shown any issue yet but it appears that it could have the same issue in the future so just preemptively change it.
