Description
At Linux Plumbers Conference 2025 in Tokyo I gave part 1 of this talk, this year I want to revisit progress made against the use cases presented last year including progress made on raw futex.
In review we'll look at systemd and if we were able to solve their most thorny calls to syscall with actual libc wrappers.
I'll include a more formal review of what is currently missing in glibc, collecting the list of syscalls for x86_64, and aarch64 and comparing to the kernel.
I will close again with a call to action for always having syscalls available as C library calls even if they could be used behind the back of the implementation.
I will propose a formal mentoring program. If you want to get a syscall wrapper into glibc I'll work with you to make it happen.
