Hi Thomas!

First off: Thank you so much for the blood, sweat and tears you have put into miniupnpd over the years. It is a nice piece of work! So thanks for that!

The issue: I recently recompiled 1.9.20150609 on Linux® with PCP enabled, and the compiler complained about an undeclared variable in pcpserver.c. The snip below is the patch I applied to allow it to compile, but I am not familiar enough with the miniupnpd code-base to know if this was the proper and sane fix to the issue. Would you mind taking a look and letting me know if this is the proper fix?


Code:
--- ./sources/miniupnpd/miniupnpd-1.9.20150609/pcpserver.c   2014-10-27 11:40:35.000000000 -0500
+++ ./sources/miniupnpd/pcpserver.c.swe   2015-06-16 08:54:17.868263523 -0500
@@ -533,7 +533,7 @@
 #endif
       opt_flp = (pcp_flow_priority_option_t*)pcp_buf;
 
-      if ( option_length != sizeof (*flp) ) {
+      if ( option_length != sizeof (*opt_flp) ) {
          syslog(LOG_ERR, "PCP: Error processing DSCP. sizeof %d and remaining %d . flow len %d \n",
                 (int)sizeof(pcp_flow_priority_option_t), remain, opt_flp->len);
          pcp_msg_info->result_code = PCP_ERR_MALFORMED_OPTION;

The problem is on line 533 of the current pcpcserver.c sources. Also it looks like 'Peter Tatrai' is that author of the pcpserver.c code.

Thanks again!

PS: This might belong in the 'minupnpd Bugs' forum instead of here.

Ah! You've read my mind on the return value ;^) Thanks!
