That's strange. Does mlockall() depend on group permissions
rather than user permissions?
If so, try running
echo '
#include <stdio.h>
#include <unistd.h>
#include <grp.h>
int main(int argc, char *argv[])
{
setreuid(geteuid(), geteuid());
setregid(getegid(), getegid());
gid_t zero = 0;
setgroups(1, &zero);
return execvp("/usr/bin/gdb", argv);
}
' | gcc -xc - -o /tmp/gdb-su && chmod +s /tmp/gdb-su
as root.
Running the resulting executable as ordinary user produces here:
a...@...:~$ /tmp/gdb-su -quiet -ex 'shell id' -ex quit
warning: not using untrusted file "/home/ap/.gdbinit"
uid=0(root) gid=0(root) groups=0(root)
This looks pretty 'root-ish' to me...
