  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ninterconnect: Fix locking for runpm vs reclaim\n\nFor cases where icc_bw_set() can be called in callbaths that could\ndeadlock against shrinker/reclaim, such as runpm resume, we need to\ndecouple the icc locking.  Introduce a new icc_bw_lock for cases where\nwe need to serialize bw aggregation and update to decouple that from\npaths that require memory allocation such as node/link creation/\ndestruction.\n\nFixes this lockdep splat:\n\n   ======================================================\n   WARNING: possible circular locking dependency detected\n   6.2.0-rc8-debug+ #554 Not tainted\n   ------------------------------------------------------\n   ring0/132 is trying to acquire lock:\n   ffffff80871916d0 (&gmu->lock){+.+.}-{3:3}, at: a6xx_pm_resume+0xf0/0x234\n\n   but task is already holding lock:\n   ffffffdb5aee57e8 (dma_fence_map){++++}-{0:0}, at: msm_job_run+0x68/0x150\n\n   which lock already depends on the new lock.\n\n   the existing dependency chain (in reverse order) is:\n\n   -> #4 (dma_fence_map){++++}-{0:0}:\n          __dma_fence_might_wait+0x74/0xc0\n          dma_resv_lockdep+0x1f4/0x2f4\n          do_one_initcall+0x104/0x2bc\n          kernel_init_freeable+0x344/0x34c\n          kernel_init+0x30/0x134\n          ret_from_fork+0x10/0x20\n\n   -> #3 (mmu_notifier_invalidate_range_start){+.+.}-{0:0}:\n          fs_reclaim_acquire+0x80/0xa8\n          slab_pre_alloc_hook.constprop.0+0x40/0x25c\n          __kmem_cache_alloc_node+0x60/0x1cc\n          __kmalloc+0xd8/0x100\n          topology_parse_cpu_capacity+0x8c/0x178\n          get_cpu_for_node+0x88/0xc4\n          parse_cluster+0x1b0/0x28c\n          parse_cluster+0x8c/0x28c\n          init_cpu_topology+0x168/0x188\n          smp_prepare_cpus+0x24/0xf8\n          kernel_init_freeable+0x18c/0x34c\n          kernel_init+0x30/0x134\n          ret_from_fork+0x10/0x20\n\n   -> #2 (fs_reclaim){+.+.}-{0:0}:\n          __fs_reclaim_acquire+0x3c/0x48\n          fs_reclaim_acquire+0x54/0xa8\n          slab_pre_alloc_hook.constprop.0+0x40/0x25c\n          __kmem_cache_alloc_node+0x60/0x1cc\n          __kmalloc+0xd8/0x100\n          kzalloc.constprop.0+0x14/0x20\n          icc_node_create_nolock+0x4c/0xc4\n          icc_node_create+0x38/0x58\n          qcom_icc_rpmh_probe+0x1b8/0x248\n          platform_probe+0x70/0xc4\n          really_probe+0x158/0x290\n          __driver_probe_device+0xc8/0xe0\n          driver_probe_device+0x44/0x100\n          __driver_attach+0xf8/0x108\n          bus_for_each_dev+0x78/0xc4\n          driver_attach+0x2c/0x38\n          bus_add_driver+0xd0/0x1d8\n          driver_register+0xbc/0xf8\n          __platform_driver_register+0x30/0x3c\n          qnoc_driver_init+0x24/0x30\n          do_one_initcall+0x104/0x2bc\n          kernel_init_freeable+0x344/0x34c\n          kernel_init+0x30/0x134\n          ret_from_fork+0x10/0x20\n\n   -> #1 (icc_lock){+.+.}-{3:3}:\n          __mutex_lock+0xcc/0x3c8\n          mutex_lock_nested+0x30/0x44\n          icc_set_bw+0x88/0x2b4\n          _set_opp_bw+0x8c/0xd8\n          _set_opp+0x19c/0x300\n          dev_pm_opp_set_opp+0x84/0x94\n          a6xx_gmu_resume+0x18c/0x804\n          a6xx_pm_resume+0xf8/0x234\n          adreno_runtime_resume+0x2c/0x38\n          pm_generic_runtime_resume+0x30/0x44\n          __rpm_callback+0x15c/0x174\n          rpm_callback+0x78/0x7c\n          rpm_resume+0x318/0x524\n          __pm_runtime_resume+0x78/0xbc\n          adreno_load_gpu+0xc4/0x17c\n          msm_open+0x50/0x120\n          drm_file_alloc+0x17c/0x228\n          drm_open_helper+0x74/0x118\n          drm_open+0xa0/0x144\n          drm_stub_open+0xd4/0xe4\n          chrdev_open+0x1b8/0x1e4\n          do_dentry_open+0x2f8/0x38c\n          vfs_open+0x34/0x40\n          path_openat+0x64c/0x7b4\n          do_filp_open+0x54/0xc4\n          do_sys_openat2+0x9c/0x100\n          do_sys_open+0x50/0x7c\n          __arm64_sys_openat+0x28/0x34\n          invoke_syscall+0x8c/0x128\n          el0_svc_common.constprop.0+0xa0/0x11c\n          do_el0_\n---truncated---",
