===================
KEY REQUEST SERVICE
===================
The key request service is part of the key retention service (refer to
Documentation/keys.txt). This document explains more fully how that the
requesting algorithm works.
The process starts by either the kernel requesting a service by calling
request_key():
struct key *request_key(const struct key_type *type,
const char *description,
const char *callout_string);
Or by userspace invoking the request_key system call:
key_serial_t request_key(const char *type,
const char *description,
const char *callout_info,
key_serial_t dest_keyring);
The main difference between the two access points is that the in-kernel
interface does not need to link the key to a keyring to prevent it from being
immediately destroyed. The kernel interface returns a pointer directly to the
key, and it's up to the caller to destroy the key.
The userspace interface links the key to a keyring associated with the process
to prevent the key from going away, and returns the serial number of the key to
the caller.
===========
THE PROCESS
===========
A request proceeds in the following manner:
(1) Process A calls request_key() [the userspace syscall calls the kernel
interface].
(2) request_key() searches the process's subscribed keyrings to see if there's
a suitable key there. If there is, it returns the key. If there isn't, and
callout_info is not set, an error is returned. Otherwise the process
proceeds to the next step.
(3) request_key() sees that A doesn't have the desired key yet, so it creates
two things:
(a) An uninstantiated key U of requested type and description.
(b) An authorisation key V that refers to key U and notes that process A
is the context in which key U should be instantiated and secured, and
from which associated key requests may be satisfied.
(4) request_key() then forks and executes /sbin/request-key with a new session
keyring that contains a link to auth key V.
(5) /sbin/request-key execs an appropriate program to perform the actual
instantiation.
(6) The program may want to access another key from A's context (say a
Kerberos TGT key). It just requests the appropriate key, and the keyring
search notes that the session keyring has auth key V in its bottom level.
This will permit it to then search the keyrings of process A with the
UID, GID, groups and security info of process A as if it was process A,
and come up with key W.
(7) The program then does what it must to get the data with which to
instantiate key U, using key W as a reference (perhaps it contacts a
Kerberos server using the TGT) and then instantiates key U.
(8) Upon instantiating key U, auth key V is automatically revoked so that it
may not be used again.
(9) The program then exits 0 and request_key() deletes key V and returns key
U to the caller.
This also extends further. If key W (step 5 above) didn't exist, key W would be
created uninstantiated, another auth key (X) would be created [as per step 3]
and another copy of /sbin/request-key spawned [as per step 4]; but the context
specified by auth key X will still be process A, as it was in auth key V.
This is because process A's keyrings can't simply be attached to
/sbin/request-key at the appropriate places because (a) execve will discard two
of them, and (b) it requires the same UID/GID/Groups all the way through.
======================
NEGATIVE INSTANTIATION
======================
Rather than instantiating a key, it is possible for the possessor of an
authorisation key to negatively instantiate a key that's under construction.
This is a short duration placeholder that causes any attempt at re-requesting
the key whilst it exists to fail with error ENOKEY.
This is provided to prevent excessive repeated spawning of /sbin/request-key
processes for a key that will never be obtainable.
Should the /sbin/request-key process exit anything other than 0 or die on a
signal, the key under construction will be automatically negatively
instantiated for a short amount of time.
====================
THE SEARCH ALGORITHM
====================
A search of any particular keyring proceeds in the following fashion:
(1) When the key management code searches for a key (keyring_search_aux) it
firstly calls key_permission(SEARCH) on the keyring it's starting with,
if this denies permission, it doesn't search further.
(2) It considers all the non-keyring keys within that keyring and, if any key
matches the criteria specified, calls key_permission(SEARCH) on it to see
if the key is allowed to be found. If it is, that key is returned; if
not, the search continues, and the error code is retained if of higher
priority than the one currently set.
(3) It then considers all the keyring-type keys in the keyring it's currently
searching. It calls key_permission(SEARCH) on each keyring, and if this
grants permission, it recurses, executing steps (2) and (3) on that
keyring.
The process stops immediately a valid key is found with permission granted to
use it. Any error from a previous match attempt is discarded and the key is
returned.
When search_process_keyrings() is invoked, it performs the following searches
until one succeeds:
(1) If extant, the process's thread keyring is searched.
(2) If extant, the process's process keyring is searched.
(3) The process's session keyring is searched.
(4) If the process has a request_key() authorisation key in its session
keyring then:
(a) If extant, the calling process's thread keyring is searched.
(b) If extant, the calling process's process keyring is searched.
(c) The calling process's session keyring is searched.
The moment one succeeds, all pending errors are discarded and the found key is
returned.
Only if all these fail does the whole thing fail with the highest priority
error. Note that several errors may have come from LSM.
The error priority is:
EKEYREVOKED > EKEYEXPIRED > ENOKEY
EACCES/EPERM are only returned on a direct search of a specific keyring where
the basal keyring does not grant Search permission.

---help---
If you say Y here, you will get support for terminal devices with
display and keyboard devices. These are called "virtual" because you
can run several virtual terminals (also called virtual consoles) on
one physical terminal. This is rather useful, for example one
virtual terminal can collect system messages and warnings, another
one can be used for a text-mode user session, and a third could run
an X session, all in parallel. Switching between virtual terminals
is done with certain key combinations, usually Alt-<function key>.
The setterm command ("man setterm") can be used to change the
properties (such as colors or beeping) of a virtual terminal. The
man page console_codes(4) ("man console_codes") contains the special
character sequences that can be used to change those properties
directly. The fonts used on virtual terminals can be changed with
the setfont ("man setfont") command and the key bindings are defined
with the loadkeys ("man loadkeys") command.
You need at least one virtual terminal device in order to make use
of your keyboard and monitor. Therefore, only people configuring an
embedded system would want to say N here in order to save some
memory; the only way to log into such a system is then via a serial
or network connection.
If unsure, say Y, or else you won't be able to do much with your new
shiny Linux system :-)
config VT_CONSOLE
bool
default y
---help---
The system console is the device which receives all kernel messages
and warnings and which allows logins in single user mode. If you
answer Y here, a virtual terminal (the device used to interact with
a physical terminal) can be used as system console. This is the most
common mode of operations, so you should say Y here unless you want
the kernel messages be output only to a serial port (in which case
you should say Y to "Console on serial port", below).
If you do say Y here, by default the currently visible virtual
terminal (/dev/tty0) will be used as system console. You can change
that with a kernel command line option such as "console=tty3" which
would use the third virtual terminal as system console. (Try "man
bootparam" or see the documentation of your boot loader (lilo or
loadlin) about how to pass options to the kernel at boot time.)
If unsure, say Y.
