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

Description:
Redirecting execution flow is a common malware
technique that can be used to compromise operating systems. To protect from 
such attacks,
the chip makers of leading architectures like x86 and arm64 have implemented 
control-flow-integrity (CFI) extensions , though they need system
software support to function. At the Linux
Security Summit North America , RISC-V kernel developer Deepak Gupta 
described the CFI
protections for that architecture and  invited community input on the
kernel support for them.
