Subject: [PATCH v3 00/16] kprobes: Unify kretprobe trampoline handlers
Date: Fri, 28 Aug 2020 01:38:34 +0900 [thread overview]
Message-ID: <159854631442.736475.5062989489155389472.stgit@devnote2> (raw)
Hi,
Here is the 3rd version of the series to unify the kretprobe trampoline handler
implementation across all architectures which are currently kprobes supported.
Previous version is here;
https://lkml.kernel.org/r/159852811819.707944.12798182250041968537.stgit@devnote2
This series removes the in_nmi() check from pre_kretprobe_handler() since we
can avoid double-lock deadlock from NMI by kprobe_busy_begin/end() and use
kfree_rcu() to release kretprobe_instance. Also, cleanup local functions to
static symbols.
Thank you,
---
