2022-06-15net: usb: ax88179_178a needs FLAG_SEND_ZLPJose Alonso
The extra byte inserted by usbnet.c when (length % dev->maxpacket == 0) is causing problems to device. This patch sets FLAG_SEND_ZLP to avoid this. Tested with: 0b95:1790 ASIX Electronics Corp. AX88179 Gigabit Ethernet Problems observed: ====================================================================== 1) Using ssh/sshfs. The remote sshd daemon can abort with the message: "message authentication code incorrect" This happens because the tcp message sent is corrupted during the USB "Bulk out". The device calculate the tcp checksum and send a valid tcp message to the remote sshd. Then the encryption detects the error and aborts. 2) NETDEV WATCHDOG: ... (ax88179_178a): transmit queue 0 timed out 3) Stop normal work without any log message. The "Bulk in" continue receiving packets normally. The host sends "Bulk out" and the device responds with -ECONNRESET. (The netusb.c code tx_complete ignore -ECONNRESET) Under normal conditions these errors take days to happen and in intense usage take hours. A test with ping gives packet loss, showing that something is wrong: ping -4 -s 462 {destination} # 462 = 512 - 42 - 8 Not all packets fail. My guess is that the device tries to find another packet starting at the extra byte and will fail or not depending on the next bytes (old buffer content). ====================================================================== Signed-off-by: Jose Alonso <joalonsof@gmail.com> Signed-off-by: David S.

2022-06-15net: ipa: stop counting total RX bytes and transactionsAlex Elder
In gsi_evt_ring_rx_update(), we update each transaction so its len field reflects the actual number of bytes received. In the process, the total number of transactions and bytes processed on the channel are summed, and added to a running total for the channel. But we don't actually use those running totals for RX endpoints. They're maintained for TX channels to support CoDel when they are associated with a "real" network device. So stop maintaining these totals for RX endpoints, and update the comment where the fields are defined to make it clear they're only valid for TX channels.

2022-06-15net: ipa: simplify TX completion statisticsAlex Elder
When a TX request is issued, its channel's accumulated byte and transaction counts are recorded. This currently does *not* take into account the transaction being committed. Later, when the transaction completes, the number of bytes and transactions that have completed since the transaction was committed are reported to the network stack. The transaction and its byte count are accounted for at that time. Instead, record the transaction and its bytes in the counts recorded at commit time. This avoids the need to do so when the transaction completes, and provides a (small) simplification of that code. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.

2022-06-15net: ipa: rename two transaction fieldsAlex Elder
There are two fields in a GSI transaction that keep track of TRE counts. The first represents the number of TREs reserved for the transaction in the TRE ring; that's currently named "tre_count". The second is the number of TREs that are actually *used* by the transaction at the time it is committed. Rename the "tre_count" field to be "rsvd_count", to make its meaning a little more specific. The "_count" is present in the name mainly to avoid interpreting it as a reserved (not-to-be-used) field. This name also distinguishes it from the "tre_count" field associated with a channel. Rename the "used" field to be "used_count", to match the convention used for reserved TREs. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2022-06-14dt-bindings: net: dsa: make reset optional and add rgmii-mode to mt7531Frank Wunderlich
A board may have no independent reset-line, so reset cannot be used inside switch driver. E.g. on Bananapi-R2 Pro switch and gmac are connected to same reset-line. Resets should be acquired only to 1 device/driver. This prevents reset to be bound to switch-driver if reset is already used for gmac. If reset is only used by switch driver it resets the switch *and* the gmac after the mdio bus comes up resulting in mdio bus goes down. It takes some time until all is up again, switch driver tries to read from mdio, will fail and defer the probe. On next try the reset does the same again. Make reset optional for such boards. Allow port 5 as cpu-port and phy-mode rgmii for mt7531. - MT7530 supports RGMII on port 5 and RGMII/TRGMII on port 6. - MT7531 supports on port 5 RGMII and SGMII (dual-sgmii) and SGMII on port 6.

Ido Schimmel says: ==================== mlxsw: Remove XM support The XM was supposed to be an external device connected to the Spectrum-{2,3} ASICs using dedicated Ethernet ports. Its purpose was to increase the number of routes that can be offloaded to hardware. This was achieved by having the ASIC act as a cache that refers cache misses to the XM where the FIB is stored and LPM lookup is performed. Testing was done over an emulator and dedicated setups in the lab, but the product was discontinued before shipping to customers. Therefore, in order to remove dead code and reduce complexity of the code base, revert the three patchsets that added XM support. ==================== Link: https://lore.kernel.org/r/20220613132116.2021055-1-idosch@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Many of these actions do the same operation, but use different data each time. Currently we create and keep every one of these actions, which use expensive and limited resources. Now we introduce a new mechanism - pattern and argument, which splits a modifying action into two parts: 1. action pattern: contains the operations to be applied on packet's header, mainly set/add/copy of fields in the packet 2. action data/argument: contains the data to be used by each operation in the pattern. This way we reuse same patterns with different arguments to create new modifying actions, and since many actions share the same operations, we end up creating a small number of patterns that we keep in a dedicated cache. These modify header patterns are implemented as new type of ICM memory, so the following kernel patch series add the support for this new ICM type. ========== * 'mlx5-next' of git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux: net/mlx5: Add bits and fields to support enhanced CQE compression net/mlx5: Remove not used MLX5_CAP_BITS_RW_MASK net/mlx5: group fdb cleanup to single function net/mlx5: Add support EXECUTE_ASO action for flow entry net/mlx5: Add HW definitions of vport debug counters net/mlx5: Add IFC bits and enums for flow meter RDMA/mlx5: Support handling of modify-header pattern ICM area net/mlx5: Manage ICM of type modify-header pattern net/mlx5: Introduce header-modify-pattern ICM properties ==================== Link: https://lore.kernel.org/r/20220614184028.51548-1-saeed@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2022-06-14ice: Fix memory corruption in VF driverPrzemyslaw Patynowski
Disable VF's RX/TX queues, when it's disabled. VF can have queues enabled, when it requests a reset. If PF driver assumes that VF is disabled, while VF still has queues configured, VF may unmap DMA resources. In such scenario device still can map packets to memory, which ends up silently corrupting it. Previously, VF driver could experience memory corruption, which lead to crash: [ 5119.170157] BUG: unable to handle kernel paging request at 00001b9780003237 [ 5119.170166] PGD 0 P4D 0 [ 5119.170173] Oops: 0002 [#1] PREEMPT_RT SMP PTI [ 5119.170181] CPU: 30 PID: 427592 Comm: kworker/u96:2 Kdump: loaded Tainted: G W I --------- - - 4.18.0-372.9.1.rt7.166.el8.x86_64 #1 [ 5119.170189] Hardware name: Dell Inc.

2022-06-14ice: Fix queue config fail handlingPrzemyslaw Patynowski
Disable VF's RX/TX queues, when VIRTCHNL_OP_CONFIG_VSI_QUEUES fail. Not disabling them might lead to scenario, where PF driver leaves VF queues enabled, when VF's VSI failed queue config. In this scenario VF should not have RX/TX queues enabled. If PF failed to set up VF's queues, VF will reset due to TX timeouts in VF driver. Initialize iterator 'i' to -1, so if error happens prior to configuring queues then error path code will not disable queue 0. Loop that configures queues will is using same iterator, so error path code will only disable queues that were configured.

2022-06-14ice: Fix PTP TX timestamp offset calculationMichal Michalik
The offset was being incorrectly calculated for E822 - that led to collisions in choosing TX timestamp register location when more than one port was trying to use timestamping mechanism. In E822 one quad is being logically split between ports, so quad 0 is having trackers for ports 0-3, quad 1 ports 4-7 etc. Each port should have separate memory location for tracking timestamps. Due to error for example ports 1 and 2 had been assigned to quad 0 with same offset (0), while port 1 should have offset 0 and 1 offset 16. Fix it by correctly calculating quad offset.
