* helpers.c: Fix undefined behavior in strndup()Xiang Wang2021-01-241-8/+9
| | | | | | | | | | | | | | Using strlen() or strdup() inside strndup() is problematic: if the input string is not null-terminated, these functions can read past the end of the buffer, which triggers undefined behavior. Rewrite the function to never read past the provided `maxlen` bound.

| | | | | | | | | | | | | | | | o Move flashbuses_to_text() to flashrom.c, it's not a cli function. o Guard `!defined(HAVE_STRNLEN)`. This guard was introduced in 23e10b87 (Add a bunch of new/tested stuff and various small changes 24) to support older BSDs. It's probably completely broken because HAVE_STRNLEN is presumably a GNU autotools thing. But we can't fix it without retesting these older BSDs.

Tested by "nicolae788" on a board with socket 754. - Mark "Multi-system" chassis as non-laptop case. - Remove W836xx log requests. We got enough (and no one is looking at them for the time being anyway). - serprog: improve invalid reply error message, contributed by Urja Rannikko. - Remove default include paths for MinGW. - Disable implicit rules in the Makefile because we don't need them and they just make the build (imperceptibly) slower. - Enable our own strnlen() implementation not only on DJGPP but also if HAVE_STRNLEN is not defined. This is needed to get older BSDs (e.g. NetBSD 6.0, FreeBSD < 8.0) to work. - Tiny other stuff. Corresponding to flashrom svn r1917.

* Make strnlen() visible in old versions of glibcStefan Tauner2015-01-271-0/+10
| | | | | | | | | | | | Strnlen() is in POSIX 2008 but was a GNU extension up to glibc 2.10 requiring to define _GNU_SOURCE. This fixes compilation on CentOS 4.9. Also, move our implementation of strnlen() that was added to support DJGPP to helpers.c. Corresponding to flashrom svn r1878.
