NAME
keyctl_chown - change the ownership of a key
SYNOPSIS
#include <keyutils.h>
long keyctl_chown(key_serial_t key, uid_t uid, gid_t gid);
DESCRIPTION
keyctl_chown()
changes the user and group ownership details of a key.
A setting of
-1
on either
uid
or
gid
will cause that setting to be ignored.
A process that does not have the
SysAdmin
capability may not change a key's UID or set the key's GID to a value that
does not match the process's GID or one of its group list.
The caller must have
setattr
permission on a key to be able to change its ownership.
RETURN VALUE
On success
keyctl_chown()
returns
0 .
On error, the value
-1
will be returned and
errno
will have been set to an appropriate error.
