2024-10-31net: hns3: fix kernel crash when 1588 is sent on HIP08 devicesJie Wang
Currently, HIP08 devices does not register the ptp devices, so the hdev->ptp is NULL. But the tx process would still try to set hardware time stamp info with SKBTX_HW_TSTAMP flag and cause a kernel crash.

2024-10-31net: hns3: fixed hclge_fetch_pf_reg accesses bar space out of bounds issueHao Lan
The TQP BAR space is divided into two segments. TQPs 0-1023 and TQPs 1024-1279 are in different BAR space addresses. However, hclge_fetch_pf_reg does not distinguish the tqp space information when reading the tqp space information. When the number of TQPs is greater than 1024, access bar space overwriting occurs. The problem of different segments has been considered during the initialization of tqp.io_base. Therefore, tqp.io_base is directly used when the queue is read in hclge_fetch_pf_reg.

2024-10-31net: hns3: Resolved the issue that the debugfs query result is inconsistent.Hao Lan
This patch modifies the implementation of debugfs: When the user process stops unexpectedly, not all data of the file system is read. In this case, the save_buf pointer is not released. When the user process is called next time, save_buf is used to copy the cached data to the user space. As a result, the queried data is inconsistent. To solve this problem, determine whether the function is invoked for the first time based on the value of *ppos. If *ppos is 0, obtain the actual data.

2024-10-31net: hns3: fixed reset failure issues caused by the incorrect reset typeHao Lan
When a reset type that is not supported by the driver is input, a reset pending flag bit of the HNAE3_NONE_RESET type is generated in reset_pending. The driver does not have a mechanism to clear this type of error. As a result, the driver considers that the reset is not complete. This patch provides a mechanism to clear the HNAE3_NONE_RESET flag and the parameter of hnae3_ae_ops.set_default_reset_request is verified.

2024-10-31net: hns3: add sync command to sync io-pgtableJian Shen
To avoid errors in pgtable prefectch, add a sync command to sync io-pagtable. This is a supplement for the previous patch. We want all the tx packet can be handled with tx bounce buffer path. But it depends on the remain space of the spare buffer, checked by the hns3_can_use_tx_bounce(). In most cases, maybe 99.99%, it returns true. But once it return false by no available space, the packet will be handled with the former path, which will map/unmap the skb buffer. Then the driver will face the smmu prefetch risk again. So add a sync command in this case to avoid smmu prefectch, just protects corner scenes.

2024-10-31net: hns3: default enable tx bounce buffer when smmu enabledPeiyang Wang
The SMMU engine on HIP09 chip has a hardware issue. SMMU pagetable prefetch features may prefetch and use a invalid PTE even the PTE is valid at that time. This will cause the device trigger fake pagefaults. The solution is to avoid prefetching by adding a SYNC command when smmu mapping a iova. But the performance of nic has a sharp drop. Then we do this workaround, always enable tx bounce buffer, avoid mapping/unmapping on TX path. This issue only affects HNS3, so we always enable tx bounce buffer when smmu enabled to improve performance.

2024-10-30mlxsw: spectrum_ipip: Fix memory leak when changing remote IPv6 addressIdo Schimmel
The device stores IPv6 addresses that are used for encapsulation in linear memory that is managed by the driver. Changing the remote address of an ip6gre net device never worked properly, but since cited commit the following reproducer [1] would result in a warning [2] and a memory leak [3]. The problem is that the new remote address is never added by the driver to its hash table (and therefore the device) and the old address is never removed from it.

2024-10-30mlxsw: spectrum_ptp: Add missing verification before pushing Tx headerAmit Cohen
Tx header should be pushed for each packet which is transmitted via Spectrum ASICs. The cited commit moved the call to skb_cow_head() from mlxsw_sp_port_xmit() to functions which handle Tx header. In case that mlxsw_sp->ptp_ops->txhdr_construct() is used to handle Tx header, and txhdr_construct() is mlxsw_sp_ptp_txhdr_construct(), there is no call for skb_cow_head() before pushing Tx header size to SKB. This flow is relevant for Spectrum-1 and Spectrum-4, for PTP packets. Add the missing call to skb_cow_head() to make sure that there is both enough room to push the Tx header and that the SKB header is not cloned and can be modified. An additional set will be sent to net-next to centralize the handling of the Tx header by pushing it to every packet just before transmission.

2024-10-29ice: fix crash on probe for DPLL enabled E810 LOMArkadiusz Kubalewski
The E810 Lan On Motherboard (LOM) design is vendor specific. Intel provides the reference design, but it is up to vendor on the final product design. For some cases, like Linux DPLL support, the static values defined in the driver does not reflect the actual LOM design. Current implementation of dpll pins is causing the crash on probe of the ice driver for such DPLL enabled E810 LOM designs: WARNING: (...) at drivers/dpll/dpll_core.c:495 dpll_pin_get+0x2c4/0x330 ...

The number of dpll pins enabled by LOM vendor is greater than expected and defined in the driver for Intel designed NICs, which causes the crash. Prevent the crash and allow generic pin initialization within Linux DPLL subsystem for DPLL enabled E810 LOM designs. Newly designed solution for described issue will be based on "per HW design" pin initialization. It requires pin information dynamically acquired from the firmware and is already in progress, planned for next-tree only.

2024-10-29igb: Disable threaded IRQ for igb_msix_otherWander Lairson Costa
During testing of SR-IOV, Red Hat QE encountered an issue where the ip link up command intermittently fails for the igbvf interfaces when using the PREEMPT_RT variant. Investigation revealed that e1000_write_posted_mbx returns an error due to the lack of an ACK from e1000_poll_for_ack. The underlying issue arises from the fact that IRQs are threaded by default under PREEMPT_RT. While the exact hardware details are not available, it appears that the IRQ handled by igb_msix_other must be processed before e1000_poll_for_ack times out. However, e1000_write_posted_mbx is called with preemption disabled, leading to a scenario where the IRQ is serviced only after the failure of e1000_write_posted_mbx. To resolve this, we set IRQF_NO_THREAD for the affected interrupt, ensuring that the kernel handles it immediately, thereby preventing the aforementioned error.

2024-10-29drm/xe/display: Separate the d3cold and non-d3cold runtime PM handlingImre Deak
For clarity separate the d3cold and non-d3cold runtime PM handling. The only change in behavior is disabling polling later during runtime resume. This shouldn't make a difference, since the poll disabling is handled from a work, which could run at any point wrt. the runtime resume handler. The work will also require a runtime PM reference, syncing it with the resume handler.

2024-10-29net: stmmac: TSO: Fix unbalanced DMA map/unmap for non-paged SKB dataFurong Xu
In case the non-paged data of a SKB carries protocol header and protocol payload to be transmitted on a certain platform that the DMA AXI address width is configured to 40-bit/48-bit, or the size of the non-paged data is bigger than TSO_MAX_BUFF_SIZE on a certain platform that the DMA AXI address width is configured to 32-bit, then this SKB requires at least two DMA transmit descriptors to serve it. For example, three descriptors are allocated to split one DMA buffer mapped from one piece of non-paged data: dma_desc[N + 0], dma_desc[N + 1], dma_desc[N + 2]. Then three elements of tx_q->tx_skbuff_dma[] will be allocated to hold extra information to be reused in stmmac_tx_clean(): tx_q->tx_skbuff_dma[N + 0], tx_q->tx_skbuff_dma[N + 1], tx_q->tx_skbuff_dma[N + 2]. Now we focus on tx_q->tx_skbuff_dma[entry].buf, which is the DMA buffer address returned by DMA mapping call. stmmac_tx_clean() will try to unmap the DMA buffer _ONLY_IF_ tx_q->tx_skbuff_dma[entry].buf is a valid buffer address. The expected behavior that saves DMA buffer address of this non-paged data to tx_q->tx_skbuff_dma[entry].buf is: tx_q->tx_skbuff_dma[N + 0].buf = NULL; tx_q->tx_skbuff_dma[N + 1].buf = NULL; tx_q->tx_skbuff_dma[N + 2].buf = dma_map_single(); Unfortunately, the current code misbehaves like this: tx_q->tx_skbuff_dma[N + 0].buf = dma_map_single(); tx_q->tx_skbuff_dma[N + 1].buf = NULL; tx_q->tx_skbuff_dma[N + 2].buf = NULL; On the stmmac_tx_clean() side, when dma_desc[N + 0] is closed by the DMA engine, tx_q->tx_skbuff_dma[N + 0].buf is a valid buffer address obviously, then the DMA buffer will be unmapped immediately. There may be a rare case that the DMA engine does not finish the pending dma_desc[N + 1], dma_desc[N + 2] yet. Now things will go horribly wrong, DMA is going to access a unmapped/unreferenced memory region, corrupted data will be transmited or iommu fault will be triggered :( In contrast, the for-loop that maps SKB fragments behaves perfectly as expected, and that is how the driver should do for both non-paged data and paged frags actually. This patch corrects DMA map/unmap sequences by fixing the array index for tx_q->tx_skbuff_dma[entry].buf when assigning DMA buffer address.

2024-10-29thunderbolt: Add only on-board retimers when !CONFIG_USB4_DEBUGFS_MARGININGMika Westerberg
Normally there is no need to enumerate retimers on the other side of the cable. This is only needed in special cases where user wants to run receiver lane margining against the downstream facing port of a retimer. Furthermore this might confuse the userspace tools such as fwupd because it cannot read the information it expects from these retimers. Fix this by changing the retimer enumeration code to add only on-board retimers when CONFIG_USB4_DEBUGFS_MARGINING is not enabled.

self-powered devices PD3.1 spec ("8.3.3.3.3 PE_SNK_Wait_for_Capabilities State") mandates that the policy engine perform a hard reset when SinkWaitCapTimer expires. Instead the code explicitly does a GET_SOURCE_CAP when the timer expires as part of SNK_WAIT_CAPABILITIES_TIMEOUT. Due to this the following compliance test failures are reported by the compliance tester (added excerpts from the PD Test Spec): * COMMON.PROC.PD.2#1: The Tester receives a Get_Source_Cap Message from the UUT. This message is valid except the following conditions: [COMMON.PROC.PD.2#1] a. The check fails if the UUT sends this message before the Tester has established an Explicit Contract ... * TEST.PD.PROT.SNK.4: ... 4. The check fails if the UUT does not send a Hard Reset between tTypeCSinkWaitCap min and max. [TEST.PD.PROT.SNK.4#1] The delay is between the VBUS present vSafe5V min and the time of the first bit of Preamble of the Hard Reset sent by the UUT.
