X-Git-Tag: cvs/fedora-glibc-20051219T1003~87
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=15a493c3b7ca29256bab871018a51673c26471ba;p=thirdparty%2Fglibc.git

* sunrpc/bindrsvprt.c (bindresvport): Wrap around to startport

	in the loop if port is bigger than endport, initially set to
	ENDPORT.  When changing startport, set endport and port
	appropriately.
