[bgpd] Pass NOSUB to regexec

2007-08-23 Paul Jakma <paul.jakma@sun.com>

	* bgp_regex.c: (bgp_regcomp) Pass NOSUB flag to regcomp to
	  prevent parsing of substitutions, which can have profound
	  performance effects on bgpd and are of no use to the CLI
	  anyway. How much it helps depends on the regex
	  implementation.
