2025-05-23i2c: I2C_DESIGNWARE_AMDISP should depend on DRM_AMD_ISPGeert Uytterhoeven
The AMD Image Signal Processor I2C functionality is only present on AMD platforms with ISP support, and its platform device is instantiated by the AMD ISP driver. Hence add a dependency on DRM_AMD_ISP, to prevent asking the user about this driver when configuring a kernel that does not support the AMD ISP.

2025-05-23drm/xe: Default auto_link_downgrade status to falseAradhya Bhatia
xe_pcode_read() can return back successfully without updating the variable 'val'. This can cause an arbitrary value to show up in the sysfs file. Allow the auto_link_downgrade_status to default to 0 to avoid any arbitrary value from coming up.

2025-05-23drm/xe/guc: Make creation of SLPC debugfs files conditionalAradhya Bhatia
Platforms that do not support SLPC are exempted from the GuC PC support. The GuC PC does not get initialized, and neither do its BOs get created. This causes a problem because the GuC PC debugfs file is still being created. Whenever the file is attempted to read, it causes a NULL pointer dereference on the supposed BO of the GuC PC. So, make the creation of SLPC debugfs files conditional to when SLPC features are supported.

2025-05-23xen/arm: call uaccess_ttbr0_enable for dm_op hypercallStefano Stabellini
dm_op hypercalls might come from userspace and pass memory addresses as parameters. The memory addresses typically correspond to buffers allocated in userspace to hold extra hypercall parameters. On ARM, when CONFIG_ARM64_SW_TTBR0_PAN is enabled, they might not be accessible by Xen, as a result ioreq hypercalls might fail. See the existing comment in arch/arm64/xen/hypercall.S regarding privcmd_call for reference. For privcmd_call, Linux calls uaccess_ttbr0_enable before issuing the hypercall thanks to commit 9cf09d68b89a. We need to do the same for dm_op. This resolves the problem.

2025-05-23xen/x86: fix initial memory balloon targetRoger Pau Monne
When adding extra memory regions as ballooned pages also adjust the balloon target, otherwise when the balloon driver is started it will populate memory to match the target value and consume all the extra memory regions added. This made the usage of the Xen `dom0_mem=,max:` command line parameter for dom0 not work as expected, as the target won't be adjusted and when the balloon is started it will populate memory straight to the 'max:' value. It would equally affect domUs that have memory != maxmem. Kernels built with CONFIG_XEN_UNPOPULATED_ALLOC are not affected, because the extra memory regions are consumed by the unpopulated allocation driver, and then balloon_add_regions() becomes a no-op.

2025-05-23xen: swiotlb: Wire up map_resource callbackJohn Ernberg
When running Xen on iMX8QXP, an Arm SoC without IOMMU, DMA performed via its eDMA v3 DMA engine fail with a mapping error. The eDMA performs DMA between RAM and MMIO space, and it's the MMIO side that cannot be mapped. MMIO->RAM DMA access cannot be bounce buffered if it would straddle a page boundary and on Xen the MMIO space is 1:1 mapped for Arm, and x86 PV Dom0. Cases where MMIO space is not 1:1 mapped, such as x86 PVH Dom0, requires an IOMMU present to deal with the mapping. Considering the above the map_resource callback can just be wired to the existing dma_direct_map_resource() function. There is nothing to do for unmap so the unmap callback is not needed.

2025-05-22bpf, sockmap: Avoid using sk_socket after free when sendingJiayuan Chen
The sk->sk_socket is not locked or referenced in backlog thread, and during the call to skb_send_sock(), there is a race condition with the release of sk_socket. All types of sockets(tcp/udp/unix/vsock) will be affected. Race conditions: ''' CPU0 CPU1 backlog::skb_send_sock sendmsg_unlocked sock_sendmsg sock_sendmsg_nosec close(fd): ... ops->release() -> sock_map_close() sk_socket->ops = NULL free(socket) sock->ops->sendmsg ^ panic here ''' The ref of psock become 0 after sock_map_close() executed. ''' void sock_map_close() { ... if (likely(psock)) { ... // !! here we remove psock and the ref of psock become 0 sock_map_remove_links(sk, psock) psock = sk_psock_get(sk); if (unlikely(!psock)) goto no_psock; <=== Control jumps here via goto ... cancel_delayed_work_sync(&psock->work); <=== not executed sk_psock_put(sk, psock); ... } ''' Based on the fact that we already wait for the workqueue to finish in sock_map_close() if psock is held, we simply increase the psock reference count to avoid race conditions. With this patch, if the backlog thread is running, sock_map_close() will wait for the backlog thread to complete and cancel all pending work. If no backlog running, any pending work that hasn't started by then will fail when invoked by sk_psock_get(), as the psock reference count have been zeroed, and sk_psock_drop() will cancel all jobs via cancel_delayed_work_sync(). In summary, we require synchronization to coordinate the backlog thread and close() thread. The panic I catched: ''' Workqueue: events sk_psock_backlog RIP: 0010:sock_sendmsg+0x21d/0x440 RAX: 0000000000000000 RBX: ffffc9000521fad8 RCX: 0000000000000001 ...

2025-05-22sched_ext: Call ops.update_idle() after updating builtin idle bitsTejun Heo
BPF schedulers that use both builtin CPU idle mechanism and ops.update_idle() may want to use the latter to create interlocking between ops.enqueue() and CPU idle transitions so that either ops.enqueue() sees the idle bit or ops.update_idle() sees the task queued somewhere. This can prevent race conditions where CPUs go idle while tasks are waiting in DSQs. For such interlocking to work, ops.update_idle() must be called after builtin CPU masks are updated. Relocate the invocation. Currently, there are no ordering requirements on transitions from idle and this relocation isn't expected to make meaningful differences in that direction. This also makes the ops.update_idle() behavior semantically consistent: any action performed in this callback should be able to override the builtin idle state, not the other way around.

2025-05-22sched_ext: Convert cgroup BPF support to use cgroup_lifetime_notifierTejun Heo

2025-05-22sched_ext: Introduce cgroup_lifetime_notifierTejun Heo
Other subsystems may make use of the cgroup hierarchy with the cgroup_bpf support being one such example. For such a feature, it's useful to be able to hook into cgroup creation and destruction paths to perform feature-specific initializations and cleanups. Add cgroup_lifetime_notifier which generates CGROUP_LIFETIME_ONLINE and CGROUP_LIFETIME_OFFLINE events whenever cgroups are created and destroyed, respectively. The next patch will convert cgroup_bpf to use the new notifier and other uses are planned. Signed-off-by: Tejun Heo <tj@kernel.org>
2025-05-22cgroup: Minor reorganization of cgroup_create()Tejun Heo
cgroup_bpf init and exit handling will be moved to a notifier chain. In prepartion, reorganize cgroup_create() a bit so that the new cgroup is fully initialized before any outside changes are made. - cgrp->ancestors[] initialization and the hierarchical nr_descendants and nr_frozen_descendants updates were in the same loop. Separate them out and do the former earlier and do the latter later. - Relocate cgroup_bpf_inherit() call so that it's after all cgroup initializations are complete. No visible behavior changes expected. Signed-off-by: Tejun Heo <tj@kernel.org>
