Имя (Name)
keyctl_session_to_parent - set the parent process's session
keyring
Синопсис (Synopsis)
#include <keyutils.h>
long keyctl_session_to_parent();
Описание (Description)
keyctl_session_to_parent() changes the session keyring to which
the calling process's parent subscribes to be the that of the
calling process.
The keyring must have link permission available to the calling
process, the parent process must have the same UIDs/GIDs as the
calling process, and the LSM must not reject the replacement.
Furthermore, this may not be used to affect init or a kernel
thread.
Note that the replacement will not take immediate effect upon the
parent process, but will rather be deferred to the next time it
returns to userspace from kernel space.
Возвращаемое значение (Return value)
On success keyctl_session_to_parent() returns 0. On error, the
value -1 will be returned and errno will have been set to an
appropriate error.
Ошибки (Error)
ENOMEM Insufficient memory to create a key.
EPERM The credentials of the parent don't match those of the
caller.
EACCES The named keyring exists, but is not linkable by the
calling process.
Ссылки (Linking)
This is a library function that can be found in libkeyutils.
When linking, -lkeyutils should be specified to the linker.
