The branch main has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=611cf392672cf7aa52a593412fb2537546a7d6a4 commit 611cf392672cf7aa52a593412fb2537546a7d6a4 Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2022-10-03 23:10:43 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2022-10-03 23:10:43 +0000 libfetch: Use memcpy in place of an odd strncpy. The length passed to strncpy is the length of the source string, not the destination buffer. This triggers a non-fatal warning in GCC 12. Hoewver, the code is also odd. It is really just a memcpy of the string without its nul terminator. For that use case, memcpy is clearer.
