[PATCH openEuler-1.0-LTS] printk: avoid deadlock in panic
by Ye Weihua 18 Mar '24

18 Mar '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I991OV -------------------------------- In the process of load testing against panic, a deadlock issue was discovered. The reason is that in the panic process, console_unlock doesn't handle the printk_context variable evenly, causing printk_context to overflow downwards, allowing vprintk_func to enter the nmi direct branch without disabling interrupt. Upon holding the logbuf_lock lock, an interrupt running wake_up_klogd_work_func was called, resulting in a deadlock. To avoid this issue, move printk_safe_ext_irqrestore after check abandon_console_lock_in_panic().
