[PATCH v7 0/6] tracing/fprobe: Fix fprobe_ip_table related bugs

[Masami Hiramatsu (Google)]

Hi,

Here is the 7th version of fprobe bugfix series.
The previous version is here.

https://lore.kernel.org/all/177615807787.1165997.921227352050738693.stgit@xxxxxxxxxxxxxxxxxxxxxxxxxxxx/

In this version, I added yet another bugfixes (again) for make
unregister_fprobe() more robust for memory pressure [2/6]. And
remove uneeded RCU sync [3/6]. And split checking whether ftrace_ops
is registered from the number of registered fprobes, because
ftrace_ops can be unregistered in module unloading[6/6].

Thank you!

Masami Hiramatsu (Google) (6):
      tracing/fprobe: Reject registration of a registered fprobe before init
      tracing/fprobe: Unregister fprobe even if memory allocation fails
      tracing/fprobe: Remove fprobe from hash in failure path
      tracing/fprobe: Avoid kcalloc() in rcu_read_lock section
      tracing/fprobe: Check the same type fprobe on table as the unregistered one
      tracing/fprobe: Fix to unregister ftrace_ops if it is empty on module unloading
