i get a 100% reproducible crash in sched_rr_get_interval().
It crashes because the popen() value in checkps() is not properly
checked for NULL.
In my case, popen() fails with errno set to 24 = (Too many open files)
Indeed, there's an obvious file descriptor leak of /proc/*/task in
isfaked() where a bunch of closedir() are missing.
int isfaked(int pidtmp) {
int count ;
struct dirent *ptr;
DIR *dirp;
char path[1000] ;
sprintf(path,"/proc/%i/task",pidtmp);
errno= 0 ;
dirp = opendir(path) ;
count = 0;
if ( errno == 0) {
while ((ptr = readdir(dirp)) != NULL) {
count++;
}
if ( count > 3 ) { return(1) ;} <===
else {return(0);} <===
}
else {return(0);} <===
}
