[$] Progress on defeating lifetime-end pointer zapping

Date:
Tue, 07 Oct 2025 15:04:16 +0000

Description:
Paul McKenney gave a remote presentation at Kangrejos2025 following up on the
talk he gave last year about the
lifetime-end-pointer-zapping problem: certain common patterns for 
multithreaded code are
technically undefined behavior, and changes to the C and C++ specifications
will be needed to correct that. Those changes could also impact code that uses
unsafe Rust, such as the kernel's Rust bindings. Progress on the problem has 
been slow,
but McKenney believes that a solution is near at hand.
