@ -42,8 +42,30 @@ Description:
modification of EVM-protected metadata and
disable all further modification of policy
Note that once a key has been loaded, it will no longer be
possible to enable metadata modification.
Echoing a value is additive, the new value is added to the
existing initialization flags.
For example, after::
echo 2 ><securityfs>/evm
another echo can be performed::
echo 1 ><securityfs>/evm
and the resulting value will be 3.
Note that once an HMAC key has been loaded, it will no longer
be possible to enable metadata modification. Signaling that an
HMAC key has been loaded will clear the corresponding flag.
For example, if the current value is 6 (2 and 4 set)::
echo 1 ><securityfs>/evm
will set the new value to 3 (4 cleared).
Loading an HMAC key is the only way to disable metadata
modification.
Until key loading has been signaled EVM can not create
or validate the 'security.evm' xattr, but returns
