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().\n\n## Affected\n\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 321794b75ac968f0bb6b9c913581949452a8d992`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 1651f5731b378616565534eb9cda30e258cebebc`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 288fdb8dcb71ec77b76ab8b8a06bc10f595ea504`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 84586322e010164eedddfcd0a0894206ae7d9317`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 68786ab0935ccd5721283b7eb7f4d2f2942c7a52`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 0362847c520747b44b574d363705d8af0621727a`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < b927c8539f692fb1f9c2f42e6c8ea2d94956f921`\n- `Linux >= 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 < 82c387ef7568c0d96a918a5a78d9cad6256cfa15`\n- `Linux 2.6.12`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
