[$] Splicing out vmsplice()
Date:
Thu, 04 Jun 2026 16:22:46 +0000
Description:
The splice() and vmsplice() system calls are meant to improve performance for certain data-movement
tasks by minimizing (or avoiding altogether) system calls and the copying
of data. They also have a long history of security problems. The recent
flood of LLM-discovered vulnerabilities has drawn attention, once again, to splice() and vmsplice() ; as a result, they may end up
being removed altogether.
