  "summary": "audit: fix possible soft lockup in __audit_inode_child()",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\naudit: fix possible soft lockup in __audit_inode_child()\n\nTracefs or debugfs maybe cause hundreds to thousands of PATH records,\ntoo many PATH records maybe cause soft lockup.\n\nFor example:\n  1. CONFIG_KASAN=y && CONFIG_PREEMPTION=n\n  2. auditctl -a exit,always -S open -k key\n  3. sysctl -w kernel.watchdog_thresh=5\n  4. mkdir /sys/kernel/debug/tracing/instances/test\n\nThere may be a soft lockup as follows:\n  watchdog: BUG: soft lockup - CPU#45 stuck for 7s! [mkdir:15498]\n  Kernel panic - not syncing: softlockup: hung tasks\n  Call trace:\n   dump_backtrace+0x0/0x30c\n   show_stack+0x20/0x30\n   dump_stack+0x11c/0x174\n   panic+0x27c/0x494\n   watchdog_timer_fn+0x2bc/0x390\n   __run_hrtimer+0x148/0x4fc\n   __hrtimer_run_queues+0x154/0x210\n   hrtimer_interrupt+0x2c4/0x760\n   arch_timer_handler_phys+0x48/0x60\n   handle_percpu_devid_irq+0xe0/0x340\n   __handle_domain_irq+0xbc/0x130\n   gic_handle_irq+0x78/0x460\n   el1_irq+0xb8/0x140\n   __audit_inode_child+0x240/0x7bc\n   tracefs_create_file+0x1b8/0x2a0\n   trace_create_file+0x18/0x50\n   event_create_dir+0x204/0x30c\n   __trace_add_new_event+0xac/0x100\n   event_trace_add_tracer+0xa0/0x130\n   trace_array_create_dir+0x60/0x140\n   trace_array_create+0x1e0/0x370\n   instance_mkdir+0x90/0xd0\n   tracefs_syscall_mkdir+0x68/0xa0\n   vfs_mkdir+0x21c/0x34c\n   do_mkdirat+0x1b4/0x1d4\n   __arm64_sys_mkdirat+0x4c/0x60\n   el0_svc_common.constprop.0+0xa8/0x240\n   do_el0_svc+0x8c/0xc0\n   el0_svc+0x20/0x30\n   el0_sync_handler+0xb0/0xb4\n   el0_sync+0x160/0x180\n\nTherefore, we add cond_resched() to __audit_inode_child() to fix it.",
