According of a documentation I have to create new session keyring when my script starts.
keyctl new_session
Sometimes the command returns the new keyring ID but often I get error message:
keyctl_session_to_parent: Operation not permitted
When it happens the content of keyring:
> cat /proc/keys
1c63fa6b I--Q--- 2 perm 1f3f0000 50848 65534 keyring _uid.50848: empty
21291866 I--Q--- 1 perm 1f3f0000 50848 65534 keyring _uid_ses.50848: 1
263af424 I--Q--- 4 perm 1f3f0000 0 65534 keyring _uid.0: empty
30e8b23b I--Q--- 11 perm 3f030000 0 0 keyring _ses: 1
Could you advice what happens and how to avoid the error message? Could it be caused by sudo?
