USER-SESSION-KEYRING(7) Linux Programmer's Manual USER-SESSION-KEYRING(7)
NAME
user-session-keyring - per-user default session keyring
DESCRIPTION
The user session keyring is a keyring used to anchor keys on behalf of a user. Each UID the kernel deals with has its own user session
keyring that is shared by all processes with that UID. The user session keyring has a name (description) of the form _uid_ses.<UID> where
<UID> is the user ID of the corresponding user.
The user session keyring is associated with the record that the kernel maintains for the UID. It comes into existence upon the first
attempt to access either the user session keyring, the user-keyring(7), or the session-keyring(7). The keyring remains pinned in existence
so long as there are processes running with that real UID or files opened by those processes remain open. (The keyring can also be pinned
indefinitely by linking it into another keyring.)
The user session keyring is created on demand when a thread requests it or when a thread asks for its session-keyring(7) and that keyring
doesn't exist. In the latter case, a user session keyring will be created and, if the session keyring wasn't to be created, the user ses-
sion keyring will be set as the process's actual session keyring.
The user session keyring is searched by request_key(2) if the actual session keyring does not exist and is ignored otherwise.
A special serial number value, KEY_SPEC_USER_SESSION_KEYRING, is defined that can be used in lieu of the actual serial number of the call-
ing process's user session keyring.
From the keyctl(1) utility, '@us' can be used instead of a numeric key ID in much the same way.
User session keyrings are independent of clone(2), fork(2), vfork(2), execve(2), and _exit(2) excepting that the keyring is destroyed when
the UID record is destroyed when the last process pinning it exits.
If a user session keyring does not exist when it is accessed, it will be created.
Rather than relying on the user session keyring, it is strongly recommended--especially if the process is running as root--that a session-
keyring(7) be set explicitly, for example by pam_keyinit(8).
NOTES
The user session keyring was added to support situations where a process doesn't have a session keyring, perhaps because it was created via
a pathway that didn't involve PAM (e.g., perhaps it was a daemon started by inetd(8)). In such a scenario, the user session keyring acts
as a substitute for the session-keyring(7).
