OpenBSD Errata: November 17th, 2018 (lockf)
17 November, 2018 by email@example.com | openbsd
Errata patches for the kernel have been released for OpenBSD 6.3 and 6.4. A recent change to POSIX file locks could cause incorrect results during lock acquisition. Binary updates for the amd64, i386, and arm64 platforms are available via the syspatch utility. Source code patches can be found on the respective errata page: https://www.openbsd.org/errata63.html https://www.openbsd.org/errata64.html As these affect the kernel, a reboot will be needed after patching.
