Subject: [ftrace/kprobes PATCH 0/3] tracing: probeevent: Fix module symbol probing
Date: Wed, 29 Aug 2018 01:17:18 +0900 [thread overview]
Message-ID: <153547303754.26502.5265242979168613920.stgit@devbox> (raw)
Hi,
This series is for fixing some bugs in Steve's ftrace/kprobes branch.
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace.git
Which is based on my fetcharg improvement series.
https://lkml.org/lkml/2018/4/25/601
This includes following fixes.
- Fix copy_from_user() misusing which Dan was reported.
- Fix to reject incorrect probeevent on loaded kernel module.
- Fix to update symbol-based argument on module.
This also checks the symbol-based argument is correct or not when
target module is loaded. If it is not correct, the event is kept
unavailable.
Thank you,
---
