Subject: [PATCH 0/4] Add sysfs interface to collect reports from debugging tools
Date: Wed, 13 Jan 2021 10:16:53 +0100 [thread overview]
Message-ID: <20210113091657.1456216-1-glider@google.com> (raw)
This patchset adds a library that captures error reports from debugging
tools like KASAN or KFENCE and exposes those reports to userspace via
sysfs. Report capturing is controlled by two new types of tracepoints:
error_report_start and error_report_end, that must be added to the tools
that want to use this new feature.
Alexander Potapenko (4):
tracing: add error_report trace points
lib: add error_report_notify to collect debugging tools' reports
kfence: use error_report_start and error_report_end tracepoints
kasan: use error_report_start and error_report_end tracepoints
