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

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\u0027s 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().\"}],\"metrics\":{},\"references\":[{\"url\":\"https://git.kernel.org/stable/c/0362847c520747b44b574d363705d8af0621727a\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/1651f5731b378616565534eb9cda30e258cebebc\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/288fdb8dcb71ec77b76ab8b8a06bc10f595ea504\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/321794b75ac968f0bb6b9c913581949452a8d992\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/68786ab0935ccd5721283b7eb7f4d2f2942c7a52\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/82c387ef7568c0d96a918a5a78d9cad6256cfa15\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/84586322e010164eedddfcd0a0894206ae7d9317\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"},{\"url\":\"https://git.kernel.org/stable/c/b927c8539f692fb1f9c2f42e6c8ea2d94956f921\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\"}]}}"
