The branch stable/13 has been updated by dim: URL: https://cgit.FreeBSD.org/src/commit/?id=1b02df092f178dc405b31cbfb2c4046059506969 commit 1b02df092f178dc405b31cbfb2c4046059506969 Author: Dimitry Andric <dim@FreeBSD.org> AuthorDate: 2026-01-15 11:31:29 +0000 Commit: Dimitry Andric <dim@FreeBSD.org> CommitDate: 2026-01-26 08:30:32 +0000 mxge(4): avoid clang 21 warning in NO-IP configuration Building the LINT-NOIP kernel on amd64 with clang 21 results in a -Werror warning similar to: sys/dev/mxge/if_mxge.c:1846:44: error: variable 'sum' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer] 1846 | cksum_offset, sizeof(sum), (caddr_t)&sum); | ^~~ Indeed, if both `INET` and `INET6` are undefined, `sum` is never initialized. Initialize it to zero to silence the warning.
