Subject: Re: [PATCH] riscv: ftrace: reject out-of-range non-direct targets
Date: Mon, 31 Aug 2026 11:50:45 +0800	[thread overview]
Message-ID: <20260901020000.1-qirui.001@bytedance.com> (raw)
In-Reply-To: <20260707121235.759104-1-qirui.001@bytedance.com>

Hi Steven,

Gentle ping on this patch. It's been over a month since submission
and I'd appreciate your review when you have a chance.

The patch fixes ftrace_modify_call() on RISC-V to properly validate
old_addr/addr instead of always treating sites as FTRACE_ADDR, and
rejects out-of-range non-direct targets that can't be dispatched
through the existing ftrace_caller path.

Thanks,
Rui
