[stunnel-users] One bug solved/fixed -- bug in log.c or perhaps options.c

Mon Oct 2 22:19:32 CEST 2006

Because I am using inetd mode, any unintended output by stunnel to 
stdout is BAD as this is accepted as input through inetd to my 
calling program.  The problem with stunnel is that in main it does 
main_initialize which has the final function "log_open"

However, somewhere in "parse_config" a call is made to "s_log" (with 
the text "Snagged 64 bytes from ..." and since this is before the 
log_open, the output ends up on stdout rather than being 
logged.  Rather than try and hunt down the function
that outputs the premature error message, I modified s_log to open 
the log files itself if not already open.

I fixed it as follows (suggest you put in to the release?):

void s_log(int level, const char *format, ...) {
     va_list 
arglist;
     char text[STRLEN], 
timestamped[STRLEN];
     time_t 
gmt;
     struct tm 
*timeptr;
#if defined(HAVE_LOCALTIME_R) && defined(_REENTRANT)
     struct tm 
timestruct;
#endif
     if(level>options.debug_level) 

         return; 

     va_start(arglist, 
format);
#ifdef HAVE_VSNPRINTF
     vsnprintf(text, STRLEN, format, 
arglist);
#else
     vsprintf(text, format, 
arglist);
#endif
     va_end(arglist); 

#if !defined (USE_WIN32) && !defined (__vms)
                         /******************** NEW CODE, NEXT 2 LINES *******/
     if(!outfile && options.output_file)   /* 'output' option 
specified, not open */
         log_open(); 

     if(!outfile && options.option.syslog) 
{
         syslog(level, "LOG%d[%lu:%lu]: 
%s",

So now I don't get the "Snagged" message back on stdout ... but it 
still does not work for me (yet :-) )
