KEYCTL_MOVE(3) Linux Key Management Calls KEYCTL_MOVE(3)
keyctl_move - Move a key between keyrings
#include <keyutils.h>
long keyctl_move(key_serial_t key, key_serial_t from_keyring,
key_serial_t to_keyring, unsigned int flags);
keyctl_move() atomically unlinks key from from_keyring and links
it into to_keyring in a single operation. Depending on the flags
set, a link to any matching key in to_keyring may get displaced.
flags is a bitwise-OR of zero or more of the following flags:
KEYCTL_MOVE_EXCL
If there's a matching key in to_keyring, don't displace it
but rather return an error.
The caller must have write permission on both keyring to be able
to create or remove links in them.
The caller must have link permission on a key to be able to
create a new link to it.
On success keyctl_move() return 0. On error, the value -1 will
be returned and errno will have been set to an appropriate error.
ENOKEY The key or one of the keyrings specified are invalid.
ENOKEY A key with the same type and description is present in
to_keyring and KEYCTL_MOVE_EXCL is set.
EKEYEXPIRED
The key or one of the keyrings specified have expired.
EKEYREVOKED
The key or one of the keyrings specified have been
revoked.
EACCES The key exists, but is not linkable by the calling
process.
EACCES The keyrings exist, but are not writable by the calling
process.
ENOMEM Insufficient memory to effect the changes.
EDQUOT Expanding to_keyring would exceed the keyring owner's
quota.
This is a library function that can be found in libkeyutils.
When linking, -lkeyutils should be specified to the linker.
