KEYCTL_SET_REQKEY_KEYRING(3)ux Key Management CallsCTL_SET_REQKEY_KEYRING(3)
keyctl_set_reqkey_keyring - set the implicit destination keyring
#include <keyutils.h>
long keyctl_set_reqkey_keyring(int reqkey_defl);
keyctl_set_reqkey_keyring() sets the default destination for implicit
key requests for the current thread and returns the old setting.
After this operation has been issued, keys acquired by implicit key
requests, such as might be performed by open() on an AFS or NFS
filesystem, will be linked by default to the specified keyring by
this function.
The valid values of reqkey_defl are:
KEY_REQKEY_DEFL_NO_CHANGE
This makes no change to the current setting.
KEY_REQKEY_DEFL_THREAD_KEYRING
This makes the thread-specific keyring the default
destination.
KEY_REQKEY_DEFL_PROCESS_KEYRING
This makes the process-specific keyring the default
destination.
KEY_REQKEY_DEFL_SESSION_KEYRING
This makes the session keyring the default destination.
KEY_REQKEY_DEFL_USER_KEYRING
This makes the UID-specific keyring the default destination.
KEY_REQKEY_DEFL_USER_SESSION_KEYRING
This makes the UID-specific session keyring the default
destination.
KEY_REQKEY_DEFL_DEFAULT
This selects the default behaviour which is to use the thread-
specific keyring if there is one, otherwise the process-
specific keyring if there is one, otherwise the session
keyring if there is one, otherwise the UID-specific session
keyring.
This setting is inherited across fork() and exec().
On success keyctl_set_reqkey_keyring() returns 0. On error, the
value -1 will be returned and errno will have been set to an
appropriate error.
EINVAL The value of reqkey_defl is invalid.
This is a library function that can be found in libkeyutils. When
linking, -lkeyutils should be specified to the linker.
