You'd probably do better to use an existing implementation rather than write your own. > and with using setuid(0) and setgid(0) why this dont work ??? These calls are not magic. Nothing within the code of an executable can get you root, unless it exploits a bug. Rather, the setuid bit on the file containing the executable makes it start as root; it's then up to the program logic to decide if it should exit with an error, run a command as root, or drop privileges and become some (different) ordinary user to run a command. > > Why are you calling two exec functions? > > i want to call the first but in the code su.c i found two functions > and i dont understand the role of the second function You broke the program logic with your edits. They key thing to realize is that once one of the exec calls executes, your program ceases to exist, because it is replaced by the program it exec'd. So only one of them will be run. -- You received this message because you are subscribed to the Google Groups "Android Security Discussions" group.
