[PATCH v2 0/2] crypto: octeontx2: Changes related to LMTST memory

by Bharat Bhushan

v1->v2: - Removed changes in pci-host-common.c, those were comitted by mistake. The first patch moves the initialization of cptlfs device info to the early probe stage, also eliminate redundant initialization. The second patch updates the driver to use a dynamically allocated memory region for LMTST instead of the statically allocated memory from firmware. It also adds myself as a maintainer.

[PATCH] drm: radeon: ci_dpm: Add error handling in ci_enable_vce_dpm()

by Wentao Liang

The ci_enable_vce_dpm() calls ci_send_msg_to_smc_with_parameter() but does not check the return value. A proper implementation can be found in the ci_upload_dpm_level_enable_mask(). Add a check after calling ci_send_msg_to_smc_with_parameter(), return -EINVAL if the sending fails.

[PATCH] HID: lenovo: Unbreak USB/BT keyboards on non-ACPI platforms

by Janne Grunau via B4 Relay

From: Janne Grunau <j(a)jannau.net> Commit 84c9d2a968c8 ("HID: lenovo: Support for ThinkPad-X12-TAB-1/2 Kbd Fn keys") added a dependency on ACPI_PLATFORM_PROFILE to cycle through power profiles. This breaks USB and Bluetooth keyboards on non-ACPI platforms since platform_profile_init() fails. See the warning below for the visible symptom but cause is the dependency on the platform_profile module.

[PATCH] RDMA/irdma: puda: Clear entries after allocation to ensure clean state

by Wentao Liang

The irdma_puda_send() calls the irdma_puda_get_next_send_wqe() to get entries, but does not clear the entries after the function call. This could lead to wqe data inconsistency. A proper implementation can be found in irdma_uk_send(). Add the irdma_clr_wqes() after irdma_puda_get_next_send_wqe(). Add the headfile of the irdma_clr_wqes().

[PATCH net] hv_netvsc: fix potential deadlock in netvsc_vf_setxdp()

by Saurabh Sengar

The MANA driver's probe registers netdevice via the following call chain: mana_probe() register_netdev() register_netdevice() register_netdevice() calls notifier callback for netvsc driver, holding the netdev mutex via netdev_lock_ops(). Further this netvsc notifier callback end up attempting to acquire the same lock again in dev_xdp_propagate() leading to deadlock. netvsc_netdev_event() netvsc_vf_setxdp() dev_xdp_propagate() This deadlock was not observed so far because net_shaper_ops was never set and this lock in noop in this case. Fix this by using netif_xdp_propagate instead of dev_xdp_propagate to avoid recursive locking in this path. This issue has not observed so far because net_shaper_ops was unset, making the lock path effectively a no-op. To prevent recursive locking and avoid this deadlock, replace dev_xdp_propagate() with netif_xdp_propagate(), which does not acquire the lock again. Also, clean up the unregistration path by removing unnecessary call to netvsc_vf_setxdp(), since unregister_netdevice_many_notify() already performs this cleanup via dev_xdp_uninstall.

[PATCH] wifi: wilc1000: Handle wilc_sdio_cmd52() failure in wilc_sdio_read_init()

by Wentao Liang

The wilc_sdio_read_init() calls wilc_sdio_cmd52() but does not check the return value. This could lead to execution with potentially invalid data if wilc_sdio_cmd52() fails. A proper implementation can be found in wilc_sdio_read_reg(). Add error handling for wilc_sdio_cmd52(). If wilc_sdio_cmd52() fails, log an error message via dev_err().

When this happens, if kmemleak fails to scan the new xa_head before it moves, kmemleak will see it as a leak until the xarray is scanned again. The report can be reproduced by running the xdp_bonding BPF selftest, although it doesn't appear consistently due to the bug's transience. In my testing, the following script has reliably triggered the report in under an hour on a debug kernel with kmemleak enabled, where KSELFTESTS is set to the install path for the kernel selftests: #!/bin/sh set -eu echo 1 >/sys/module/kmemleak/parameters/verbose echo scan=1 >/sys/kernel/debug/kmemleak while :; do $KSELFTESTS/bpf/test_progs -t xdp_bonding done To prevent this false positive report, mark the new xa_head in xas_shrink() as a transient leak.

Even though the code setting the flag is designed to prevent it, there are subtle cases where the flag could be true at the mutex_lock stage and false at the mutex_unlock stage. This results in the mutex not being unlocked, resulting in a deadlock.

[PATCH v2 1/2] xhci: Add a quirk for full reset on removal

by Roy Luo

Commit 6ccb83d6c497 ("usb: xhci: Implement xhci_handshake_check_state() helper") introduced an optimization to xhci_reset() during xhci removal, allowing it to bail out early without waiting for the reset to complete. This behavior can cause issues on SNPS DWC3 USB controller with dual-role capability. When the DWC3 controller exits host mode and removes xhci while a reset is still in progress, and then tries to configure its hardware for device mode, the ongoing reset leads to register access issues; specifically, all register reads returns 0. These issues extend beyond the xhci register space (which is expected during a reset) and affect the entire DWC3 IP block, causing the DWC3 device mode to malfunction. To address this, introduce the `XHCI_FULL_RESET_ON_REMOVE` quirk. When this quirk is set, xhci_reset() always completes its reset handshake, ensuring the controller is in a fully reset state before proceeding.

[PATCH v1 1/3] s390/uv: don't return 0 from make_hva_secure() if the operation was not successful

by David Hildenbrand

If s390_wiggle_split_folio() returns 0 because splitting a large folio succeeded, we will return 0 from make_hva_secure() even though a retry is required. Return -EAGAIN in that case. Otherwise, we'll return 0 from gmap_make_secure(), and consequently from unpack_one(). In kvm_s390_pv_unpack(), we assume that unpacking succeeded and skip unpacking this page. Later on, we run into issues and fail booting the VM. So far, this issue was only observed with follow-up patches where we split large pagecache XFS folios. Maybe it can also be triggered with shmem? We'll cleanup s390_wiggle_split_folio() a bit next, to also return 0 if no split was required.

[PATCH v3 rc] iommu: Skip PASID validation for devices without PASID capability

by Tushar Dave

Generally PASID support requires ACS settings that usually create single device groups, but there are some niche cases where we can get multi-device groups and still have working PASID support. The primary issue is that PCI switches are not required to treat PASID tagged TLPs specially so appropriate ACS settings are required to route all TLPs to the host bridge if PASID is going to work properly. pci_enable_pasid() does check that each device that will use PASID has the proper ACS settings to achieve this routing. However, no-PASID devices can be combined with PASID capable devices within the same topology using non-uniform ACS settings. In this case the no-PASID devices may not have strict route to host ACS flags and end up being grouped with the PASID devices. This configuration fails to allow use of the PASID within the iommu core code which wrongly checks if the no-PASID device supports PASID. Fix this by ignoring no-PASID devices during the PASID validation. They will never issue a PASID TLP anyhow so they can be ignored.
