“…The NUMA configuration of recent architecture designs from AMD (e.g., Zen2) [30] and Huawei (Kunpeng) [48] can be modified off-line at boot time. An appropriate selection of the NUMA scheme, depending on the server target applications, is therefore crucial to achieve the goals of isolation and contention control.…”

“…The execution-time overhead cannot be directly measured without MTE hardware or cycle-accurate emulators; neither is publicly available yet. Therefore, we instrument the benchmarks with emulated MTE overhead analogues (Section 8.3.1) and run them on a TaiShan 2280 Balanced Model [10] with a Kunpeng 920 CPU [37], an ARMv8 class-A CPU without MTE support. We measured the run time of each benchmark using the GNU/Linux time utility over 10 runs each.…”

Hardware-assisted memory protection features are increasingly being deployed in COTS processors. ARMv8.5 Memory Tagging Extensions (MTE) is a recent example, which has been used to provide probabilistic checks for memory safety. This use of MTE is not secure against the standard adversary with arbitrary read/write access to memory. Consequently MTE is used as a software development tool. In this paper we present the first design for deterministic memory protection using MTE that can resist the standard adversary, and hence is suitable for post-deployment memory safety. We describe our compiler extensions for LLVM Clang implementing static analysis and subsequent MTE instrumentation. Via a comprehensive evaluation we show that our scheme is effective.
