From f45217e776c937b677653c287d63b54ac8281bba Mon Sep 17 00:00:00 2001 From: Rainer Gerhards Date: Tue, 29 Sep 2009 14:37:33 +0200 Subject: bugfix: zero-sized UDP messages are no longer processed Until now, they were forwarded to processing, but this makes no sense Also, it looks like the system seems to provide a zero return code on a UDP recvfrom() from time to time for some internal reasons. These "receives" are now silently ignored. --- plugins/imudp/imudp.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'plugins/imudp') diff --git a/plugins/imudp/imudp.c b/plugins/imudp/imudp.c index 658ceb23..6f4a6384 100644 --- a/plugins/imudp/imudp.c +++ b/plugins/imudp/imudp.c @@ -178,6 +178,9 @@ processSocket(int fd, struct sockaddr_storage *frominetPrev, int *pbIsPermitted, ABORT_FINALIZE(RS_RET_ERR); } + if(lenRcvBuf == 0) + continue; /* this looks a bit strange, but practice shows it happens... */ + /* if we reach this point, we had a good receive and can process the packet received */ /* check if we have a different sender than before, if so, we need to query some new values */ if(net.CmpHost(&frominet, frominetPrev, socklen) != 0) { -- cgit
