In case it may help, I have a look at innd. This processes use 2 execv:
one to execute /bin/sh and the other to execute itself:
/*
** Re-exec ourselves.
*/
static const char *
CCxexec(char *av[])
{
char *innd;
char *p;
int i;
if (CCargv == NULL)
return "1 no argv!";
innd = concatpath(innconf->pathbin, "innd");
/* Get the pathname. */
p = av[0];
if (*p == '\0' || strcmp(p, "innd") == 0)
CCargv[0] = innd;
else
return "1 Bad value";
#ifdef DO_PERL
PLmode(Mode, OMshutdown, av[0]);
#endif
#ifdef DO_PYTHON
PYmode(Mode, OMshutdown, av[0]);
#endif
JustCleanup();
syslog(L_NOTICE, "%s execv %s", LogName, CCargv[0]);
/* Close all fds to protect possible fd leaking accross successive
innds. */
for (i=3; i<30; i++)
close(i);
execv(CCargv[0], CCargv);
syslog(L_FATAL, "%s cant execv %s %m", LogName, CCargv[0]);
_exit(1);
/* NOTREACHED */
return "1 Exit failed";
}
The culprit may be /usr/local/news/bin/innd,
remember that find is locked in /usr/local/news/bin
