8 daysnet: hns3: default enable tx bounce buffer when smmu enabledJijie Shao
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.

8 dayss390/ism: fix concurrency management in ism_cmd()Halil Pasic
The s390x ISM device data sheet clearly states that only one request-response sequence is allowable per ISM function at any point in time. Unfortunately as of today the s390/ism driver in Linux does not honor that requirement. This patch aims to rectify that. This problem was discovered based on Aliaksei's bug report which states that for certain workloads the ISM functions end up entering error state (with PEC 2 as seen from the logs) after a while and as a consequence connections handled by the respective function break, and for future connection requests the ISM device is not considered -- given it is in a dysfunctional state. During further debugging PEC 3A was observed as well. A kernel message like [ 1211.244319] zpci: 061a:00:00.0: Event 0x2 reports an error for PCI function 0x61a is a reliable indicator of the stated function entering error state with PEC 2. Let me also point out that a kernel message like [ 1211.244325] zpci: 061a:00:00.0: The ism driver bound to the device does not support error recovery is a reliable indicator that the ISM function won't be auto-recovered because the ISM driver currently lacks support for it. On a technical level, without this synchronization, commands (inputs to the FW) may be partially or fully overwritten (corrupted) by another CPU trying to issue commands on the same function. There is hard evidence that this can lead to DMB token values being used as DMB IOVAs, leading to PEC 2 PCI events indicating invalid DMA. But this is only one of the failure modes imaginable. In theory even completely losing one command and executing another one twice and then trying to interpret the outputs as if the command we intended to execute was actually executed and not the other one is also possible. Frankly, I don't feel confident about providing an exhaustive list of possible consequences.

9 daysPCI/pwrctrl: Create pwrctrl devices only when CONFIG_PCI_PWRCTRL is enabledManivannan Sadhasivam
If devicetree describes power supplies related to a PCI device, we unnecessarily created a pwrctrl device even if CONFIG_PCI_PWRCTL was not enabled. We only need pci_pwrctrl_create_device() when CONFIG_PCI_PWRCTRL is enabled. Compile it out when CONFIG_PCI_PWRCTRL is not enabled. When pci_pwrctrl_create_device() creates and returns a pwrctrl device, pci_scan_device() doesn't enumerate the PCI device. It assumes the pwrctrl core will rescan the bus after turning on the power. However, if CONFIG_PCI_PWRCTRL is not enabled, the rescan never happens, which breaks PCI enumeration on any system that describes power supplies in devicetree but does not use pwrctrl. Jim reported that some brcmstb platforms break this way. The brcmstb driver is still broken if CONFIG_PCI_PWRCTRL is enabled, but this commit at least allows brcmstb to work when it's NOT enabled.

10 daysRevert "drm/nouveau: check ioctl command codes better"Arnd Bergmann
My previous patch ended up causing a regression for the DRM_IOCTL_NOUVEAU_NVIF ioctl. The intention of my patch was to only pass ioctl commands that have the correct dir/type/nr bits into the nouveau_abi16_ioctl() function. This turned out to be too strict, as userspace does use at least write-only and write-read direction settings. Checking for both of these still did not fix the issue, so the best we can do for the 6.16 release is to revert back to what we've had since linux-3.16. This version is still fragile, but at least it is known to work with existing userspace. Fixing this properly requires a better understanding of what commands are being passed from userspace in practice, and how that relies on the undocumented (miss)behavior in nouveau_drm_ioctl().

There are 2 code path that call struct can_priv::do_set_mode: - directly by a manual restart from the user space, via can_changelink() - delayed automatic restart after bus off (deactivated by default) To prevent the NULL pointer deference, refuse a manual restart or configure the automatic restart delay in can_changelink() and report the error via extack to user space.

10 daysgve: Fix stuck TX queue for DQ queue formatPraveen Kaligineedi
gve_tx_timeout was calculating missed completions in a way that is only relevant in the GQ queue format. Additionally, it was attempting to disable device interrupts, which is not needed in either GQ or DQ queue formats. As a result, TX timeouts with the DQ queue format likely would have triggered early resets without kicking the queue at all. This patch drops the check for pending work altogether and always kicks the queue after validating the queue has not seen a TX timeout too recently.

10 daysi40e: When removing VF MAC filters, only check PF-set MACJamie Bainbridge
When the PF is processing an Admin Queue message to delete a VF's MACs from the MAC filter, we currently check if the PF set the MAC and if the VF is trusted. This results in undesirable behaviour, where if a trusted VF with a PF-set MAC sets itself down (which sends an AQ message to delete the VF's MAC filters) then the VF MAC is erased from the interface. This results in the VF losing its PF-set MAC which should not happen. There is no need to check for trust at all, because an untrusted VF cannot change its own MAC. The only check needed is whether the PF set the MAC. If the PF set the MAC, then don't erase the MAC on link-down. Resolve this by changing the deletion check only for PF-set MAC. (the out-of-tree driver has also intentionally removed the check for VF trust here with OOT driver version 2.26.8, this changes the Linux kernel driver behaviour and comment to match the OOT driver behaviour) Fixes: ea2a1cfc3b201 ("i40e: Fix VF MAC filter removal") Signed-off-by: Jamie Bainbridge <jamie.bainbridge@gmail.com> Reviewed-by: Simon Horman <horms@kernel.org> Tested-by: Rafal Romanowski <rafal.romanowski@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>
10 daysi40e: report VF tx_dropped with tx_errors instead of tx_discardsDennis Chen
Currently the tx_dropped field in VF stats is not updated correctly when reading stats from the PF. This is because it reads from i40e_eth_stats.tx_discards which seems to be unused for per VSI stats, as it is not updated by i40e_update_eth_stats() and the corresponding register, GLV_TDPC, is not implemented[1]. Use i40e_eth_stats.tx_errors instead, which is actually updated by i40e_update_eth_stats() by reading from GLV_TEPC.

13 daysnet/mlx5: E-Switch, Fix peer miss rules to use peer eswitchShahar Shitrit
In the original design, it is assumed local and peer eswitches have the same number of vfs. However, in new firmware, local and peer eswitches can have different number of vfs configured by mlxconfig. In such configuration, it is incorrect to derive the number of vfs from the local device's eswitch. Fix this by updating the peer miss rules add and delete functions to use the peer device's eswitch and vf count instead of the local device's information, ensuring correct behavior regardless of vf configuration differences.

13 daysnet: ti: icssg-prueth: Fix buffer allocation for ICSSGHimanshu Mittal
Fixes overlapping buffer allocation for ICSSG peripheral used for storing packets to be received/transmitted. There are 3 buffers: 1. Buffer for Locally Injected Packets 2. Buffer for Forwarding Packets 3. Buffer for Host Egress Packets In existing allocation buffers for 2. and 3. are overlapping causing packet corruption. Packet corruption observations: During tcp iperf testing, due to overlapping buffers the received ack packet overwrites the packet to be transmitted. So, we see packets on wire with the ack packet content inside the content of next TCP packet from sender device.

two distinct buffer configuration functions that are invoked based on the driver state and ICSSG firmware:- - prueth_fw_offload_buffer_setup() - prueth_emac_buffer_setup() During initialization, driver creates standard network interfaces (netdevs) and configures buffers via prueth_emac_buffer_setup(). This function properly allocates and configures all required memory regions including: - LI buffers - Express packet buffers - Preemptible packet buffers However, when the driver transitions to an offload mode (switch/HSR/PRP), buffer reconfiguration is handled by prueth_fw_offload_buffer_setup(). This function does not reconfigure the buffer regions required for Express packets, leading to incorrect buffer allocation.

13 daysdpaa2-switch: Fix device reference count leak in MAC endpoint handlingMa Ke
The fsl_mc_get_endpoint() function uses device_find_child() for localization, which implicitly calls get_device() to increment the device's reference count before returning the pointer. However, the caller dpaa2_switch_port_connect_mac() fails to properly release this reference in multiple scenarios. We should call put_device() to decrement reference count properly. As comment of device_find_child() says, 'NOTE: you will need to drop the reference with put_device() after use'. Found by code review.

The fsl_mc_get_endpoint() function may call fsl_mc_device_lookup() twice, which would increment the device's reference count twice if both lookups find a device.
