[$] Unexporting kallsyms_lookup_name()

One of the basic rules of kernel-module development is that modules can only access symbols (functions and data structures) that have been explicitly exported. Even then, many symbols are restricted so that only modules with a GPL-compatible license can access them. It turns out, though, that there is a readily available workaround that makes it easy for a m […]

[$] An end to high memory?

This patch from Johannes Weiner seemed like a straightforward way to improve memory-reclaim performance; without it, the virtual filesystem layer throws away memory that the memory-management subsystem thinks is still worth keeping. But that patch quickly ran afoul of a feature (or "misfeature" depending on who one asks) from the distant past, one […]

[$] Impedance matching for BPF and LSM

The "kernel runtime security instrumentation" (KRSI) patch set has been making the rounds over the past few months; the idea is to use the Linux security module (LSM) hooks as a way to detect, and potentially deflect, active attacks against a running system. It does so by allowing BPF programs to be attached to the LSM hooks. That has caused some c […]

[$] A look at "BPF Performance Tools"

BPF has exploded within the Linux world over the last few years, growing from its networking roots into the go-to tool for running custom in-kernel programs. Its role seems to expand with every kernel release into diverse areas such as security and device control. But none of that is the focus of a relatively new book from Brendan Gregg, BPF Performance Tool […]

Show me Your Clipboard Data!, (Fri, Feb 28th) 28 Φεβρουαρίου, 2020

Yesterday I&#39;ve read an article[1] about the clipboard on iPhones and how it can disclose sensitive information about the device owner. At the end of the article, the author gave a reference to an iPhone app[2] that discloses the metadata of pictures copied to the clipboard (like the GPS coordinates).
