Integrity Policy Enforcement relies on immutable security properties of the system component and is engineered for fixed-function systems like network firewall devices, IoT platforms, etc, that are only ever running certain application-targeted code. This Integrity Policy Enforcement isn't intended just for general PC or server use with software from a myriad of sources/vendors.
With Integrity Policy Enforcement, administrators can restrict execution of binaries to only those that come from an integrity-protected storage device, like a DM-VERITY using file-system.

The IPE LSM was merged as part of the LSM updates for Linux 6.12 .
