Matheus	9a9740469f	kcov: move thread attach from open to start ... The current kcov code attaches a kcov object to the thread which opened it. This is not desirable, as syzkaller opens /dev/kcov in a parent process and passes it down to the child. Move the thread attachment from open() time to start time.	2026-10-08 18:42:25 -03:00
Matheus	e4a4896b4b	kcov: initial implementation ... Implement a device (/dev/kcov) that exposes coverage info for the kernel. This will be especially useful for coverage-based fuzzing (e.g. syzkaller). Exclude a lot of functions which would crash/otherwise interfere in the coverage, including only processing coverage callbacks when not handling an irq.	2026-10-06 11:51:02 -03:00
