From 15a493c3b7ca29256bab871018a51673c26471ba Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Tue, 22 Nov 2005 04:39:40 +0000 Subject: * 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. --- sunrpc/bindrsvprt.c | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) (limited to 'sunrpc') diff --git a/sunrpc/bindrsvprt.c b/sunrpc/bindrsvprt.c index f58d3b2..023ae17 100644 --- a/sunrpc/bindrsvprt.c +++ b/sunrpc/bindrsvprt.c @@ -74,14 +74,13 @@ bindresvport (int sd, struct sockaddr_in *sin) int res = -1; int nports = ENDPORT - startport + 1; + int endport = ENDPORT; again: for (i = 0; i < nports; ++i) { sin->sin_port = htons (port++); - if (port > ENDPORT) - { - port = startport; - } + if (port > endport) + port = startport; res = __bind (sd, sin, sizeof (struct sockaddr_in)); if (res >= 0 || errno != EADDRINUSE) break; @@ -90,7 +89,9 @@ bindresvport (int sd, struct sockaddr_in *sin) if (i == nports && startport != LOWPORT) { startport = LOWPORT; + endport = STARTPORT - 1; nports = STARTPORT - LOWPORT; + port = LOWPORT + port % (STARTPORT - LOWPORT); goto again; } -- cgit v1.1
