| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nsched/core: Prevent rescheduling when interrupts are disabled\n\nDavid reported a warning observed while loop testing kexec jump:\n\n Interrupts enabled after irqrouter_resume+0x0/0x50\n WARNING: CPU: 0 PID: 560 at drivers/base/syscore.c:103 syscore_resume+0x18a/0x220\n kernel_kexec+0xf6/0x180\n __do_sys_reboot+0x206/0x250\n do_syscall_64+0x95/0x180\n\nThe corresponding interrupt flag trace:\n\n hardirqs last enabled at (15573): [<ffffffffa8281b8e>] __up_console_sem+0x7e/0x90\n hardirqs last disabled at (15580): [<ffffffffa8281b73>] __up_console_sem+0x63/0x90\n\nThat means __up_console_sem() was invoked with interrupts enabled. Further\ninstrumentation revealed that in the interrupt disabled section of kexec\njump one of the syscore_suspend() callbacks woke up a task, which set the\nNEED_RESCHED flag. A later callback in the resume path invoked\ncond_resched() which in turn led to the invocation of the scheduler:\n\n __cond_resched+0x21/0x60\n down_timeout+0x18/0x60\n acpi_os_wait_semaphore+0x4c/0x80\n acpi_ut_acquire_mutex+0x3d/0x100\n acpi_ns_get_node+0x27/0x60\n acpi_ns_evaluate+0x1cb/0x2d0\n acpi_rs_set_srs_method_data+0x156/0x190\n acpi_pci_link_set+0x11c/0x290\n irqrouter_resume+0x54/0x60\n syscore_resume+0x6a/0x200\n kernel_kexec+0x145/0x1c0\n __do_sys_reboot+0xeb/0x240\n do_syscall_64+0x95/0x180\n\nThis is a long standing problem, which probably got more visible with\nthe recent printk changes. Something does a task wakeup and the\nscheduler sets the NEED_RESCHED flag. cond_resched() sees it set and\ninvokes schedule() from a completely bogus context. The scheduler\nenables interrupts after context switching, which causes the above\nwarning at the end.\n\nQuite some of the code paths in syscore_suspend()/resume() can result in\ntriggering a wakeup with the exactly same consequences. They might not\nhave done so yet, but as they share a lot of code with normal operations\nit's just a question of time.\n\nThe problem only affects the PREEMPT_NONE and PREEMPT_VOLUNTARY scheduling\nmodels. Full preemption is not affected as cond_resched() is disabled and\nthe preemption check preemptible() takes the interrupt disabled flag into\naccount.\n\nCure the problem by adding a corresponding check into cond_resched()." |
