The /sys/kernel/livepatch directory contains subdirectories for each loaded live patch module.
What: /sys/kernel/livepatch/<patch>Date: Nov 2014KernelVersion: 3.19.0Contact: live-patching@vger.kernel.orgDescription: The patch directory contains subdirectories for each kernel object (vmlinux or a module) in which it patched functions.
What: /sys/kernel/livepatch/<patch>/enabledDate: Nov 2014KernelVersion: 3.19.0Contact: live-patching@vger.kernel.orgDescription: A writable attribute that indicates whether the patched code is currently applied. Writing 0 will disable the patch while writing 1 will re-enable the patch.
What: /sys/kernel/livepatch/<patch>/transitionDate: Feb 2017KernelVersion: 4.12.0Contact: live-patching@vger.kernel.orgDescription: An attribute which indicates whether the patch is currently in transition.
What: /sys/kernel/livepatch/<patch>/forceDate: Nov 2017KernelVersion: 4.15.0Contact: live-patching@vger.kernel.orgDescription: A writable attribute that allows administrator to affect the course of an existing transition. Writing 1 clears TIF_PATCH_PENDING flag of all tasks and thus forces the tasks to the patched or unpatched state. Administrator should not use this feature without a clearance from a patch distributor. Removal (rmmod) of patch modules is permanently disabled when the feature is used. See Documentation/livepatch/livepatch.rst for more information.
What: /sys/kernel/livepatch/<patch>/replaceDate: Jun 2024KernelVersion: 6.11.0Contact: live-patching@vger.kernel.orgDescription: An attribute which indicates whether the patch supports atomic-replace.
What: /sys/kernel/livepatch/<patch>/stack_orderDate: Jan 2025KernelVersion: 6.14.0Description: This attribute specifies the sequence in which live patch modules are applied to the system. If multiple live patches modify the same function, the implementation with the biggest 'stack_order' number is used, unless a transition is currently in progress.
What: /sys/kernel/livepatch/<patch>/<object>Date: Nov 2014KernelVersion: 3.19.0Contact: live-patching@vger.kernel.orgDescription: The object directory contains subdirectories for each function that is patched within the object.
What: /sys/kernel/livepatch/<patch>/<object>/patchedDate: August 2022KernelVersion: 6.1.0Contact: live-patching@vger.kernel.orgDescription: An attribute which indicates whether the object is currently patched.
What: /sys/kernel/livepatch/<patch>/<object>/<function,sympos>Date: Nov 2014KernelVersion: 3.19.0Contact: live-patching@vger.kernel.orgDescription: The function directory contains attributes regarding the properties and state of the patched function.
The directory name contains the patched function name and a sympos number corresponding to the nth occurrence of the symbol name in kallsyms for the patched object.
There are currently no such attributes.
