plumbers talk on kCFI, BTI, & IBT?

[Nick Desaulniers]

Hi Sami, Peter, Joao, and Mark,
Jose and I are currently in the planning process to put together a
Kernel+Toolchain microconference track at Linux Plumbers Conference
this year (Sept 12-14) in Dublin, Ireland.  Would you all be
interested in a session on Control Flow Integrity in the kernel?
Mitigations in hardware, software, or both might be of interest to
discuss more in person?

Thanks,
~Nick Desaulniers

Yeah, I think a session on CFI in general would be good to have.

Yup, seems like a good idea.

Sounds good. I'll do my best to be around.

Tks,

Putting Rick into this loop! He is in charge of handling kernel support for user-space IBT.
