NAME

       keyctl_set_reqkey_keyring - Set the implicit destination keyring

SYNOPSIS

       #include <keyutils.h>

       long keyctl_set_reqkey_keyring(int reqkey_defl);

DESCRIPTION

       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().

RETURN VALUE

       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.

ERRORS

       EINVAL The value of reqkey_defl is invalid.

LINKING

       This is a library function that can be found in libkeyutils.  When linking, -lkeyutils should be specified to the linker.

NAME

       keyctl_join_session_keyring - Join a different session keyring

SYNOPSIS

       #include <keyutils.h>

       key_serial_t keyctl_join_session_keyring(const char *name);

DESCRIPTION

       keyctl_join_session_keyring() changes the session keyring to which a process is subscribed.

       If name is NULL then a new anonymous keyring will be created, and the process will be subscribed to that.

       If  name  points to a string, then if a keyring of that name is available, the process will attempt to subscribe to that keyring, giving an
       error if that is not permitted; otherwise a new keyring of that name is created and attached as the session keyring.

       To attach to an extant named keyring, the keyring must have search permission available to the calling process.

RETURN VALUE

       On success keyctl_join_session_keyring() returns the serial number of the key it found or created.  On error, the value -1 will be returned
       and errno will have been set to an appropriate error.

ERRORS

       ENOMEM Insufficient memory to create a key.

       EDQUOT The key quota for this user would be exceeded by creating this key or linking it to the keyring.

       EACCES The named keyring exists, but is not searchable by the calling process.

LINKING

       This is a library function that can be found in libkeyutils.  When linking, -lkeyutils should be specified to the linker.
