2022-06-15net: usb: ax88179_178a needs FLAG_SEND_ZLPJose Alonso1-13/+13
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 <[email protected]> Signed-off-by: David S.

2022-06-14ice: Fix memory corruption in VF driverPrzemyslaw Patynowski1-0/+5
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 Patynowski1-27/+26
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 Michalik2-1/+32
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.

2022-06-14mlxsw: spectrum_cnt: Reorder counter poolsPetr Machata1-1/+1
Both RIF and ACL flow counters use a 24-bit SW-managed counter address to communicate which counter they want to bind. In a number of Spectrum FW releases, binding a RIF counter is broken and slices the counter index to 16 bits. As a result, on Spectrum-2 and above, no more than about 410 RIF counters can be effectively used. This translates to 205 netdevices for which L3 HW stats can be enabled. (This does not happen on Spectrum-1, because there are fewer counters available overall and the counter index never exceeds 16 bits.) Binding counters to ACLs does not have this issue. Therefore reorder the counter allocation scheme so that RIF counters come first and therefore get lower indices that are below the 16-bit barrier.

2022-06-13amd-xgbe: Use platform_irq_count()Jean-Philippe Brucker1-2/+2
The AMD XGbE driver currently counts the number of interrupts assigned to the device by inspecting the pdev->resource array. Since commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from DT core") removed IRQs from this array, the driver now attempts to get all interrupts from 1 to -1U and gives up probing once it reaches an invalid interrupt index. Obtain the number of IRQs with platform_irq_count() instead.

2022-06-13net: axienet: Use iowrite64 to write all 64b descriptor pointersAndy Chiu1-3/+18
According to commit f735c40ed93c ("net: axienet: Autodetect 64-bit DMA capability") and AXI-DMA spec (pg021), on 64-bit capable dma, only writing MSB part of tail descriptor pointer causes DMA engine to start fetching descriptors. However, we found that it is true only if dma is in idle state. In other words, dma would use a tailp even if it only has LSB updated, when the dma is running. The non-atomicity of this behavior could be problematic if enough delay were introduced in between the 2 writes. For example, if an interrupt comes right after the LSB write and the cpu spends long enough time in the handler for the dma to get back into idle state by completing descriptors, then the seconcd write to MSB would treat dma to start fetching descriptors again. Since the descriptor next to the one pointed by current tail pointer is not filled by the kernel yet, fetching a null descriptor here causes a dma internal error and halt the dma engine down. We suggest that the dma engine should start process a 64-bit MMIO write to the descriptor pointer only if ONE 32-bit part of it is written on all states. Or we should restrict the use of 64-bit addressable dma on 32-bit platforms, since those devices have no instruction to guarantee the write to LSB and MSB part of tail pointer occurs atomically to the dma. initial condition: curp = x-3; tailp = x-2; LSB = x; MSB = 0; cpu: |dma: iowrite32(LSB, tailp) | completes #(x-3) desc, curp = x-3 ... | tailp updated => irq | completes #(x-2) desc, curp = x-2 ... | completes #(x-1) desc, curp = x-1 ... | ... ... | completes #x desc, curp = tailp = x <= irqreturn | reaches tailp == curp = x, idle iowrite32(MSB, tailp + 4) | ... | tailp updated, starts fetching... | fetches #(x + 1) desc, sees cntrl = 0 | post Tx error, halt Signed-off-by: Andy Chiu <[email protected]> Reported-by: Max Hsu <[email protected]> Reviewed-by: Greentime Hu <[email protected]> Signed-off-by: David S.

2022-06-13net: axienet: make the 64b addresable DMA depends on 64b archecturesAndy Chiu2-24/+40
Currently it is not safe to config the IP as 64-bit addressable on 32-bit archectures, which cannot perform a double-word store on its descriptor pointers. The pointer is 64-bit wide if the IP is configured as 64-bit, and the device would process the partially updated pointer on some states if the pointer was updated via two store-words. To prevent such condition, we force a probe fail if we discover that the IP has 64-bit capability but it is not running on a 64-Bit kernel. This is a series of patch (1/2). The next patch must be applied in order to make 64b DMA safe on 64b archectures.

2022-06-09nfp: avoid unnecessary check warnings in nfp_app_get_vf_configFei Qin1-13/+15
nfp_net_sriov_check is added in nfp_app_get_vf_config which intends to ensure ivi->vlan_proto and ivi->max_tx_rate/min_tx_rate can be read from VF config table only when firmware supports corresponding capability. However, "nfp_app_get_vf_config" can be called by commands like "ip a", "ip link set $DEV up" and "ip link set $DEV vf $NUM vlan $param" (with VF). When using commands above, many warnings "ndo_set_vf_<cap_x> not supported" would appear if firmware doesn't support VF rate limit and 802.1ad VLAN assingment. If more VFs are created, things could get worse. Thus, this patch add an extra bool parameter for nfp_net_sriov_check to enable/disable the cap check warning report. Unnecessary warnings in nfp_app_get_vf_config can be avoided. Valid warnings in kinds of vf setting function can be reserved.

2022-06-09mellanox: mlx5: avoid uninitialized variable warning with gcc-12Linus Torvalds1-1/+1
gcc-12 started warning about 'tracker' being used uninitialized: drivers/net/ethernet/mellanox/mlx5/core/lag/lag.c: In function ‘mlx5_do_bond’: drivers/net/ethernet/mellanox/mlx5/core/lag/lag.c:786:28: warning: ‘tracker’ is used uninitialized [-Wuninitialized] 786 | struct lag_tracker tracker; | ^~~~~~~ which seems to be because it doesn't track how the use (and initialization) is bound by the 'do_bond' flag. But admittedly that 'do_bond' usage is fairly complicated, and involves passing it around as an argument to helper functions, so it's somewhat understandable that gcc doesn't see how that all works. This function could be rewritten to make the use of that tracker variable more obviously safe, but for now I'm just adding the forced initialization of it.

After reinitialization of iavf, ice driver gets VIRTCHNL_OP_ADD_ETH_ADDR message with incorrectly set type of MAC address. Hardware address should have is_primary flag set as true. This way ice driver knows what it has to set as a MAC address. Check if the address is primary in iavf_add_filter function and set flag accordingly. To test set all-zero MAC on a VF. This triggers iavf re-initialization and VIRTCHNL_OP_ADD_ETH_ADDR message gets sent to PF. For example: ip link set dev ens785 vf 0 mac 00:00:00:00:00:00 This triggers re-initialization of iavf.

After PF reset and ethtool -t there was call trace in dmesg sometimes leading to panic. When there was some time, around 5 seconds, between reset and test there were no errors. Problem was that pf reset calls i40e_vsi_close in prep_for_reset and ethtool -t calls i40e_vsi_close in diag_test. If there was not enough time between those commands the second i40e_vsi_close starts before previous i40e_vsi_close was done which leads to crash. Add check to diag_test if pf is in reset and don't start offline tests if it is true.

2022-06-08net: dsa: realtek: rtl8365mb: fix GMII caps for ports with internal PHYAlvin Šipraga1-29/+9
Since commit a18e6521a7d9 ("net: phylink: handle NA interface mode in phylink_fwnode_phy_connect()"), phylib defaults to GMII when no phy-mode or phy-connection-type property is specified in a DSA port node of the device tree. The same commit caused a regression in rtl8365mb whereby phylink would fail to connect, because the driver did not advertise support for GMII for ports with internal PHY. It should be noted that the aforementioned regression is not because the blamed commit was incorrect: on the contrary, the blamed commit is correcting the previous behaviour whereby unspecified phy-mode would cause the internal interface mode to be PHY_INTERFACE_MODE_NA. The rtl8365mb driver only worked by accident before because it _did_ advertise support for PHY_INTERFACE_MODE_NA, despite NA being reserved for internal use by phylink. With one mistake fixed, the other was exposed. Commit a5dba0f207e5 ("net: dsa: rtl8365mb: add GMII as user port mode") then introduced implicit support for GMII mode on ports with internal PHY to allow a PHY connection for device trees where the phy-mode is not explicitly set to "internal". At this point everything was working OK again. Subsequently, commit 6ff6064605e9 ("net: dsa: realtek: convert to phylink_generic_validate()") broke this behaviour again by discarding the usage of rtl8365mb_phy_mode_supported() - where this GMII support was indicated - while switching to the new .phylink_get_caps API. With the new API, rtl8365mb_phy_mode_supported() is no longer needed. Remove it altogether and add back the GMII capability - this time to rtl8365mb_phylink_get_caps() - so that the above default behaviour works for ports with internal PHY again.

The {dma|pio}_mode sysfs files are incorrectly documented as having a list of the supported DMA/PIO transfer modes, while the corresponding fields of the *struct* ata_device hold the transfer mode IDs, not masks. To match these docs, the {dma|pio}_mode (and even xfer_mode!) sysfs files are handled by the ata_bitfield_name_match() macro which leads to reading such kind of nonsense from them: $ cat /sys/class/ata_device/dev3.0/pio_mode XFER_UDMA_7, XFER_UDMA_6, XFER_UDMA_5, XFER_UDMA_4, XFER_MW_DMA_4, XFER_PIO_6, XFER_PIO_5, XFER_PIO_4, XFER_PIO_3, XFER_PIO_2, XFER_PIO_1, XFER_PIO_0 Using the correct ata_bitfield_name_search() macro fixes that: $ cat /sys/class/ata_device/dev3.0/pio_mode XFER_PIO_4 While fixing the file documentation, somewhat reword the {dma|pio}_mode file doc and add a note about being mostly useful for PATA devices to the xfer_mode file doc...
