While uid_t and gid_t are both unsigned, the values (uid_t) -1 and
|
|
(gid_t) -1 are reserved. A uid or gid argument of -1 to the chown(2)
|
|
system call means to leave the uid/gid unchanged. Catch this case
|
|
so that trying to set a uid or gid to -1 will result in an error.
|
|
|
|
Test cases:
|
|
|
|
chown 4294967295 file
|
|
chown :4294967295 file
|
|
chgrp 4294967295 file
