[NFS-Ganesha-Devel] Change in ...nfs-ganesha[next]: coverity: string is not null terminated (do not merge)

Kaleb KEITHLEY has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/458987 Change subject: coverity: string is not null terminated (do not merge) ...................................................................... coverity: string is not null terminated (do not merge) Now with utf8string_dup(). But do not merge because this adds more coverity warnings than it fixes. Fixes an issue (of sorts) reported by coverity, namely not enough memory is allocated to store a terminating NULL in a utf8string. The warning is a false positive. utf8strings in ganesha are nominally strings that come off the wire and may or may not be null terminated; given that, it is not safe to call strlen(). Furthermore, they need not be NULL terminated when stored internally as the length is stored in an associated length variable. In this case the string comes from an xattr and should contain a ':' separator. The ':' separator, if there is one, is replaced with a null by strsep(). By convention it should still be considered not safe to call strlen() or (gsh_)strdup(), but gsh_strdup() is used everywhere else in ganesha for utf8strings, so we do it here as well. Foolish consistency and all that. At least we know it's safe here. And it should silence the coverity warning. Unfortunately simply adding a /* coverity[OVERRUN] */ comment here did not silence it.
