The atomic replace allows to create cumulative patches. They are useful when you maintain many livepatches and want to remove one that is lower on the stack. In addition it is very useful when more patches touch the same function and there are dependencies between them. Changes against v6: + used list_move when disabling replaced patches [Jason] + renamed KLP_FUNC_ORIGINAL -> KLP_FUNC_STATIC [Mirek] + used klp_is_func_type() in klp_unpatch_object() [Mirek] + moved static definition of klp_get_or_add_object() [Mirek] + updated comment about synchronization in forced mode [Mirek] + added user documentation + fixed several typos Jason Baron (5): livepatch: Use lists to manage patches, objects and functions livepatch: Initial support for dynamic structures livepatch: Allow to unpatch only functions of the given type livepatch: Support separate list for replaced patches. livepatch: Add atomic replace Petr Mladek (2): livepatch: Free only structures with initialized kobject livepatch: Atomic replace and cumulative patches documentation Documentation/livepatch/cumulative-patches.txt | 76 +++++ include/linux/livepatch.h | 59 +++- kernel/livepatch/core.c | 378 ++++++++++++++++++++++--- kernel/livepatch/core.h | 4 + kernel/livepatch/patch.c | 29 +- kernel/livepatch/patch.h | 4 +- kernel/livepatch/transition.c | 41 ++- 7 files changed, 543 insertions(+), 48 deletions(-) create mode 100644 Documentation/livepatch/cumulative-patches.txt -- 2.13.6 -- To unsubscribe from this list: send the line "unsubscribe live-patching" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
