# Memorizer Memorizer is a tool to trace fine-grained intra-kernel operations. The goal is to track interactions with memory objects for the purpose of analyzing fine-grained interactions amongst components and execution contexts. Memorizer tracks the following object operations: creation (alloc), destruction (free), modify (store), access (load), call, and return. Nathan D. ([@ndauten]) presented the umbrella project, Opportunistic Privilege Separation (OPS), and Memorizer at the [7/9/17 LinuxKit SIG](../../reports/2017-07-09.md) and [slides](http://nathandautenhahn.com/talks/2017-06-21_ops+memorizer-linuxkit-sig/linuxkit-sig-remark.html#1) ## Usage See [manual usage docs](./docs/memorizer.txt). Be careful though because if the event queues are not drained then the system will run out of memory. For controlled use see [script + readme](./docs/memorizer/). This script is not automatically inserted into the runtime yet. ## Issues - KASAN is reporting some errors within itself. This is noisy. Can reduce the console log output level to < 3, e.g., `echo 3 > /proc/sys/kernel/printk` - Source should be included soon, but for now there is an image on Docker Hub.
