81 | * These are reasons that can be passed to the security_locked_down() | |
82 | * LSM hook. Lockdown reasons that protect kernel integrity (ie, the | |
83 | * ability for userland to modify kernel code) are placed before | |
84 | * LOCKDOWN_INTEGRITY_MAX. Lockdown reasons that protect kernel | |
85 | * confidentiality (ie, the ability for userland to extract | |
86 | * information from the running kernel that would otherwise be | |
87 | * restricted) are placed before LOCKDOWN_CONFIDENTIALITY_MAX. | |
88 | * | |
89 | * LSM authors should note that the semantics of any given lockdown | |
90 | * reason are not guaranteed to be stable - the same reason may block | |
91 | * one set of features in one kernel release, and a slightly different | |
92 | * set of features in a later kernel release. LSMs that seek to expose | |
93 | * lockdown policy at any level of granularity other than "none", | |
94 | * "integrity" or "confidentiality" are responsible for either | |
95 | * ensuring that they expose a consistent level of functionality to | |
96 | * userland, or ensuring that userland is aware that this is | |
97 | * potentially a moving target. It is easy to misuse this information | |
98 | * in a way that could break userspace. Please be careful not to do | |
99 | * so. | |
