From: Pablo Neira Ayuso Date: Tue, 16 Aug 2016 21:22:51 +0000 (+0200) Subject: scanner: allow strings starting by underscores and dots X-Git-Tag: v0.7~118 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=57ecffc9d1e551ecc0546806ca9c008e93c2ecf3;p=thirdparty%2Fnftables.git scanner: allow strings starting by underscores and dots POSIX.1-2008 (which is simultaneously IEEE Std 1003.1-2008) says: "The set of characters from which portable filenames are constructed. A B C D E F G H I J K L M N O P Q R S T U V W X Y Z a b c d e f g h i j k l m n o p q r s t u v w x y z 0 1 2 3 4 5 6 7 8 9 . _ -" On top of that it says: "The character should not be used as the first character of a portable user name." This allows a bit more things that NAME_REGEX though, but this still looks fine to me.
