[$] Improving control-flow integrity for Linux on RISC-V

Redirecting execution flow is a common malwaretechnique that can be used to compromise operating systems. To protect from such attacks,the chip makers of leading architectures like x86 and arm64 have implementedcontrol-flow-integrity (CFI) extensions, though they need systemsoftware support to function. At the LinuxSecurity Summit North America, RISC-V kernel developer Deepak Gupta described the CFIprotections for that architecture and invited community input on thekernel support for them.
