The branch main has been updated by brooks: URL: https://cgit.FreeBSD.org/src/commit/?id=72a4ee26a7c665ae1c31abe1c6feeaa7ccaba140 commit 72a4ee26a7c665ae1c31abe1c6feeaa7ccaba140 Author: Brooks Davis <brooks@FreeBSD.org> AuthorDate: 2023-10-16 16:53:11 +0000 Commit: Brooks Davis <brooks@FreeBSD.org> CommitDate: 2023-10-16 16:58:37 +0000 libprocstat: make sv_name not static Making this variable static makes is_elf32_sysctl() and callers thread unsafe. Use a less absurd length for sv_name. The longest name in the system is "FreeBSD ELF64 V2" which tips the scales at 16+1 bytes. We'll almost certainly have other problems if we exceed 32 characters.
