12 If you are unsure how to answer this question, answer N.
14 config EVM_ATTR_FSUUID
15 bool "FSUUID (version 2)"
19 Include filesystem UUID for HMAC calculation.
21 Default value is 'selected', which is former version 2.
22 if 'not selected', it is former version 1
24 WARNING: changing the HMAC calculation method or adding
25 additional info to the calculation, requires existing EVM
26 labeled file systems to be relabeled.
28 config EVM_EXTRA_SMACK_XATTRS
29 bool "Additional SMACK xattrs"
30 depends on EVM && SECURITY_SMACK
33 Include additional SMACK xattrs for HMAC calculation.
35 In addition to the original security xattrs (eg. security.selinux,
36 security.SMACK64, security.capability, and security.ima) included
37 in the HMAC calculation, enabling this option includes newly defined

41 WARNING: changing the HMAC calculation method or adding
42 additional info to the calculation, requires existing EVM
43 labeled file systems to be relabeled.
46 bool "Add additional EVM extended attributes at runtime"
50 Allow userland to provide additional xattrs for HMAC calculation.
52 When this option is enabled, root can add additional xattrs to the
53 list used by EVM by writing them into
54 /sys/kernel/security/integrity/evm/evm_xattrs.
57 bool "Load an X509 certificate onto the '.evm' trusted keyring"
58 depends on EVM && INTEGRITY_TRUSTED_KEYRING
61 Load an X509 certificate onto the '.evm' trusted keyring.
63 This option enables X509 certificate loading from the kernel
64 onto the '.evm' trusted keyring. A public key can be used to
65 verify EVM integrity starting from the 'init' process.
68 string "EVM X509 certificate path"
69 depends on EVM_LOAD_X509
70 default "/etc/keys/x509_evm.der"
72 This option defines X509 certificate path.
