Software updates typically require stopping and restarting an application, but many systems
cannot afford to halt service, or would prefer not to. Dynamic software updating (DSU) …

Ksplice allows system administrators to apply patches to their operating system kernels
without rebooting. Unlike previous hot update systems, Ksplice operates at the object code …

This paper describes an operating system (OS) called Theseus. Theseus is the result of
multi-year experimentation to redesign and improve OS modularity by reducing the states …

Software evolves to fix bugs and add features. Stopping and restarting programs to apply
changes is inconvenient and often costly. Dynamic software updating (DSU) addresses this …

Microkernels have been extensively studied over decades. However, IPC (Inter-Process
Communication) is still a major factor of runtime overhead, where fine-grained isolation …

Kernel-level rootkits affect system security by modifying key kernel data structures to achieve
a variety of malicious goals. While early rootkits modified control data structures, such as the …

This paper presents POLUS, a software maintenance tool capable of iteratively evolving
running software into newer versions. POLUS's primary goal is to increase the dependability …

We propose a new approach for dynamic software updates. This approach allows updating
applications that until now could not be updated at runtime at all or could be updated but …

Memory corruption attacks are a pre-dominant attack vector against IoT devices. Simply
updating vulnerable IoT software is not always possible due to unacceptable downtime and …

Many dynamic updating systems have been developed that enable a program to be patched
while it runs, to fix bugs or add new features. This paper explores techniques for supporting …
