plumbers session on syscall wrapping and kernel header libc circular depdence?

[Nick Desaulniers]

Hi Florian, Arnd, and Masahiro,
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 (if you're planning on
attending) discussing syscall wrapping for libc's and UAPI circular
dependency on the libc?

Masahiro and I were recently discussing the feasibility of building
the kernel UAPI header tests with -nostdinc, but there are some
interesting complications perhaps worth sharing with others?

I'm not sure if I will be able to travel by that time.

To be honest, that doesn't seem to be a good use of a session slot.
Surely we can figure out a way to solve this issue offline (and if it's
a problem worth solving)?

(I expect that using -nostdinc makes it more difficult to support
compilers which are not GCC-compatible.)

Thanks,
Florian

Hello Nick,

Sorry for the late reply.

I am not sure about the travel at the moment.
I may be able to attend it remotely if the the plumbers is held as a
hybrid conference.

I am not quite sure how many developers would be interested in this topic,
but we can continue discussion in the ML as well.

Bummer.

I think it will be.

Ok, based on the feedback, we will scrap the idea for the topic. I
will follow up with the UAPI discussions on the list.
