keyctl_search
KEYCTL_SEARCH(3) Linux Key Management Calls KEYCTL_SEARCH(3)
NAME
keyctl_search - Search a keyring for a key
SYNOPSIS
#include <keyutils.h>
long keyctl_search(key_serial_t keyring, const char *type,
const char *description, key_serial_t destination);
DESCRIPTION
keyctl_search() recursively searches the keyring for a key of the specified type and description.
If found, the key will be attached to the destination keyring (if given), and its serial number will be returned.
The source keyring must grant search permission to the caller, and for a key to be found, it must also grant search permission to the call-
er. Child keyrings will be only be recursively searched if they grant search permission to the caller as well.
If the destination keyring is zero, no attempt will be made to forge a link to the key, and just the serial number will be returned.
If the destination keyring is given, then the link may only be formed if the found key grants the caller link permission and the destina-
tion keyring grants the caller write permission.
If the search is successful, and if the destination keyring already contains a link to a key that matches the specified type and descrip-
tion, then that link will be replaced by a link to the found key.
The source keyring and destination keyring serial numbers may be those of valid keyrings to which the caller has appropriate permission, or
they may be special keyring IDs:
KEY_SPEC_THREAD_KEYRING
This specifies the caller's thread-specific keyring.
KEY_SPEC_PROCESS_KEYRING
This specifies the caller's process-specific keyring.
KEY_SPEC_SESSION_KEYRING
This specifies the caller's session-specific keyring.
KEY_SPEC_USER_KEYRING
This specifies the caller's UID-specific keyring.
KEY_SPEC_USER_SESSION_KEYRING
This specifies the caller's UID-session keyring.
RETURN VALUE
On success keyctl_search() returns the serial number of the key it found. On error, the value -1 will be returned and errno will have been
set to an appropriate error.
ERRORS
ENOKEY One of the keyrings doesn't exist, no key was found by the search, or the only key found by the search was a negative key.
ENOTDIR
One of the keyrings is a valid key that isn't a keyring.
EKEYEXPIRED
One of the keyrings has expired, or the only key found was expired.
EKEYREVOKED
One of the keyrings has been revoked, or the only key found was revoked.
ENOMEM Insufficient memory to expand the destination keyring.
EDQUOT The key quota for this user would be exceeded by creating a link to the found key in the destination keyring.
EACCES The source keyring didn't grant search permission, the destination keyring didn't grant write permission or the found key didn't
grant link permission to the caller.
LINKING
Although this is a Linux system call, it is not present in libc but can be found rather in libkeyutils. When linking, -lkeyutils should be
specified to the linker.
