Merge tag 'trace-v6.17-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull tracing fixes from Steven Rostedt:

- Fix buffer overflow in osnoise_cpu_write()

The allocated buffer to read user space did not add a nul terminating
byte after copying from user the string. It then reads the string,
and if user space did not add a nul byte, the read will continue
beyond the string.

Add a nul terminating byte after reading the string.

- Fix missing check for lockdown on tracing

There's a path from kprobe events or uprobe events that can update
the tracing system even if lockdown on tracing is activate. Add a
check in the dynamic event path.

- Add a recursion check for the function graph return path

Now that fprobes can hook to the function graph tracer and call
different code between the entry and the exit, the exit code may now
call functions that are not called in entry. This means that the exit
handler can possibly trigger recursion that is not caught and cause
the system to crash.

Add the same recursion checks in the function exit handler as exists
in the entry handler path.
