Revision be28c14ac8bbe1ff0b2a18a06cd10981f90fc741 authored by Kuniyuki Iwashima on 14 June 2023, 19:47:04 UTC, committed by Jakub Kicinski on 15 June 2023, 22:08:58 UTC
Recently syzkaller reported a 7-year-old null-ptr-deref [0] that occurs when a UDP-Lite socket tries to allocate a buffer under memory pressure. Someone should have stumbled on the bug much earlier if UDP-Lite had been used in a real app. Also, we do not always need a large UDP-Lite workload to hit the bug since UDP and UDP-Lite share the same memory accounting limit. Removing UDP-Lite would simplify UDP code removing a bunch of conditionals in fast path. Let's add a deprecation notice when UDP-Lite socket is created and schedule its removal to 2025.
