G06F009/44, G06F009/445
US Classification:
717/170000, 717/175000
Abstract:
A system and method for automatically updating software components on a running computer system without requiring any interruption of service. A software module is hotpatched by loading a patch into memory and modifying an instruction in the original module to jump to the patch. A coldpatching technique places a coldpatch version of the module on disk for subsequent loading by processes, after hotpatching occurred. The coldpatch has the entry points to its functions at the same relative locations within the module as the hotpatch, which facilitates subsequent hotpatching. A hotpatch and coldpatch are automatically generated by deriving differences between changed and original binary files, and establishing the point to insert the jump. Validation is performed to ensure that the hotpatch is applied to the correct version, and that the coldpatch is replacing the correct version. Version management is also provided to control the number of patches via support rules.

International Classification:
G06F 9/44
US Classification:
717168000
Abstract:
Runtime patch validation is provided that instruments an in-use function to determine whether the function needs a patch and/or how the patch will impact the function. Patch validation code is instrumented into a target binary when the target binary is running. Patch validation data is gathered from the instrumented target binary and provided for viewing and analysis.
