Abstract:
An application is modified during execution by a hotpatch controller of a kernel receiving one or more new versions of a selection of one or more functions of multiple functions of an application and at least one selection criteria for applying the one or more new versions to the application during execution of the application to update a selection of one or more existing versions of the one or more functions. The hotpatch controller selectively transfers control from the selection of one or more existing versions of the one or more functions to the one or more new versions for only a selection of one or more processes that call the selection of one or more existing versions of the one or more functions from among multiple processes of the application, the selection of one or more processes each comprising one or more attributes matching the at least one selection criteria.
