KEYCTL_CHOWN(3) Linux Key Management Calls KEYCTL_CHOWN(3)
keyctl_chown - change the ownership of a key
#include <keyutils.h>
long keyctl_chown(key_serial_t key, uid_t uid, gid_t gid);
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.
On success keyctl_chown() returns 0 . On error, the value -1
will be returned and errno will have been set to an appropriate
error.
ENOKEY The specified key does not exist.
EKEYEXPIRED
The specified key has expired.
EKEYREVOKED
The specified key has been revoked.
EDQUOT Changing the UID to the one specified would run that UID
out of quota.
EACCES The key exists, but does not grant setattr permission to
the calling process.
This is a library function that can be found in libkeyutils.
When linking, -lkeyutils should be specified to the linker.
