The Git Mailing List Archive on lore.kernel.org (found in the README from the git mirror on GitHub) has more context [0] [1] [2]. From Jeff King on 2018-07-24: The strncpy() function is less horrible than strcpy(), but is still pretty easy to misuse because of its funny termination semantics. Namely, that if it truncates it omits the NUL terminator, and you must remember to add it yourself. Even if you use it correctly, it's sometimes hard for a reader to verify this without hunting through the code. If you're thinking about using it, consider instead: - strlcpy() if you really just need a truncated but NUL-terminated string (we provide a compat version, so it's always available) - xsnprintf() if you're sure that what you're copying should fit - strbuf or xstrfmt() if you need to handle arbitrary-length heap-allocated strings I just did a search on the keywords 'banned' and 'strncpy' [2] [0] https://lore.kernel.org/git/20180724092828.GD3288@sigill.intra.peff.net/ https://lore.kernel.org/git/20180724092828.GD3288@sigill.int...
