System call wrappers for glibc: discussion at the Linux Plumbers Conference
Carlos O'Donell and Florian Weimer, glibc maintainers, updated participants on Linux system calls that lack a wrapper in the library and asked the community about its needs.
According to the report published in the LWN feed, Carlos O'Donell returned to the topic of system call wrappers for the GNU C library (glibc) at this year's Linux Plumbers Conference, this time joined by Florian Weimer, another glibc maintainer. The session continues a talk he gave at the 2025 edition of the same event. The goal was to update attendees on what changed over the past year regarding Linux system calls that have no glibc wrapper and therefore can only be reached through syscall().
The organizers also wanted to hear from participants about their needs in this area.
