[ Upstream commit ebf35d8f9368816c930f5d70783a72716fab5e19 ] Before sending the data via the mailbox to the hardware, to ensure that the data accessed by the hardware is the most up-to-date, a write barrier should be added before writing to the mailbox register. The current memory barrier is placed after writing to the register, the barrier order should be modified to be before writing to the register.

2026-03-04crypto: ccp - Send PSP_CMD_TEE_RING_DESTROY when PSP_CMD_TEE_RING_INIT failsMario Limonciello (AMD)1-0/+14
[ Upstream commit 7b85137caf110a09a4a18f00f730de4709f9afc8 ] The hibernate resume sequence involves loading a resume kernel that is just used for loading the hibernate image before shifting back to the existing kernel. During that hibernate resume sequence the resume kernel may have loaded the ccp driver. If this happens the resume kernel will also have called PSP_CMD_TEE_RING_INIT but it will never have called PSP_CMD_TEE_RING_DESTROY. This is problematic because the existing kernel needs to re-initialize the ring. One could argue that the existing kernel should call destroy as part of restore() but there is no guarantee that the resume kernel did or didn't load the ccp driver. There is also no callback opportunity for the resume kernel to destroy before handing back control to the existing kernel. Similar problems could potentially exist with the use of kdump and crash handling. I actually reproduced this issue like this: 1) rmmod ccp 2) hibernate the system 3) resume the system 4) modprobe ccp The resume kernel will have loaded ccp but never destroyed and then when I try to modprobe it fails. Because of these possible cases add a flow that checks the error code from the PSP_CMD_TEE_RING_INIT call and tries to call PSP_CMD_TEE_RING_DESTROY if it failed. If this succeeds then call PSP_CMD_TEE_RING_INIT again.

[ Upstream commit 7d43252b3060b0ba4a192dce5dba85a3f39ffe39 ] When commit 0e1a4d427f58 ("crypto: caam: Unembed net_dev structure in dpaa2") converted embedded net_device to dynamically allocated pointers, it added cleanup in dpaa2_dpseci_disable() but missed adding cleanup in dpaa2_dpseci_free() for error paths. This causes memory leaks when dpaa2_dpseci_dpio_setup() fails during probe due to DPIO devices not being ready yet. The kernel's deferred probe mechanism handles the retry successfully, but the netdevs allocated during the failed probe attempt are never freed, resulting in kmemleak reports showing multiple leaked netdev-related allocations all traced back to dpaa2_caam_probe(). Fix this by preserving the CPU mask of allocated netdevs during setup and using it for cleanup in dpaa2_dpseci_free(). This approach ensures that only the CPUs that actually had netdevs allocated will be cleaned up, avoiding potential issues with CPU hotplug scenarios.

2026-03-04crypto: ccp - Ensure implicit SEV/SNP init and shutdown in ioctlsAshish Kalra1-23/+119
[ Upstream commit ceac7fb89e8da465aec3ac3c20477f912f5c3a6c ] Modify the behavior of implicit SEV initialization in some of the SEV ioctls to do both SEV initialization and shutdown and add implicit SNP initialization and shutdown to some of the SNP ioctls so that the change of SEV/SNP platform initialization not being done during PSP driver probe time does not break userspace tools such as sevtool, etc. Prior to this patch, SEV has always been initialized before these ioctls as SEV initialization is done as part of PSP module probe, but now with SEV initialization being moved to KVM module load instead of PSP driver probe, the implied SEV INIT actually makes sense and gets used and additionally to maintain SEV platform state consistency before and after the ioctl SEV shutdown needs to be done after the firmware call. It is important to do SEV Shutdown here with the SEV/SNP initialization moving to KVM, an implicit SEV INIT here as part of the SEV ioctls not followed with SEV Shutdown will cause SEV to remain in INIT state and then a future SNP INIT in KVM module load will fail. Also ensure that for these SEV ioctls both implicit SNP and SEV INIT is done followed by both SEV and SNP shutdown as RMP table must be initialized before calling SEV INIT if SNP host support is enabled. Similarly, prior to this patch, SNP has always been initialized before these ioctls as SNP initialization is done as part of PSP module probe, therefore, to keep a consistent behavior, SNP init needs to be done here implicitly as part of these ioctls followed with SNP shutdown before returning from the ioctl to maintain the consistent platform state before and after the ioctl.

commit 59b0afd01b2ce353ab422ea9c8375b03db313a21 upstream. The qm_get_qos_value() function calls bus_find_device_by_name() which increases the device reference count, but fails to call put_device() to balance the reference count and lead to a device reference leak. Add put_device() calls in both the error path and success path to properly balance the reference count. Found via static analysis.

[ Upstream commit 2b0dc40ac6ca16ee0c489927f4856cf9cd3874c7 ] payload_size field of the request header is incorrectly calculated using sizeof(req). Since 'req' is a pointer (struct hsti_request *), sizeof(req) returns the size of the pointer itself (e.g., 8 bytes on a 64-bit system), rather than the size of the structure it points to. This leads to an incorrect payload size being sent to the Platform Security Processor (PSP), potentially causing the HSTI query command to fail. Fix this by using sizeof(*req) to correctly calculate the size of the struct hsti_request.

commit 3d4df408ba9bad2b205c7fb8afc1836a6a4ca88a upstream. Repeated loading and unloading of a device specific QAT driver, for example qat_4xxx, in a tight loop can lead to a crash due to a use-after-free scenario. This occurs when a power management (PM) interrupt triggers just before the device-specific driver (e.g., qat_4xxx.ko) is unloaded, while the core driver (intel_qat.ko) remains loaded. Since the driver uses a shared workqueue (`qat_misc_wq`) across all devices and owned by intel_qat.ko, a deferred routine from the device-specific driver may still be pending in the queue. If this routine executes after the driver is unloaded, it can dereference freed memory, resulting in a page fault and kernel crash like the following: BUG: unable to handle page fault for address: ffa000002e50a01c #PF: supervisor read access in kernel mode RIP: 0010:pm_bh_handler+0x1d2/0x250 [intel_qat] Call Trace: pm_bh_handler+0x1d2/0x250 [intel_qat] process_one_work+0x171/0x340 worker_thread+0x277/0x3a0 kthread+0xf0/0x120 ret_from_fork+0x2d/0x50 To prevent this, flush the misc workqueue during device shutdown to ensure that all pending work items are completed before the driver is unloaded.
