Subject: Re: [PATCH v1 1/5] SUNRPC: fire svc_xprt_free tracepoint before dropping the netns
Date: Tue, 22 Sep 2026 01:57:33 +0000 [thread overview]
Message-ID: <20260922015734.00D6D1F000FF@smtp.kernel.org> (raw)
In-Reply-To: <20260922015128.240977-1-cel@kernel.org>
> svc_xprt_free() releases the transport's network namespace
> reference and then fires trace_svc_xprt_free(), which reads
> xpt_net->ns.inum through SVC_XPRT_ENDPOINT_ASSIGNMENTS. When the
> transport holds the last reference, the namespace is already on
> the cleanup list by the time the tracepoint reads it. The window
> is narrow, since cleanup_net() runs from a workqueue, but nothing
> holds the namespace alive across it.
>
> Fire the tracepoint before any of the teardown steps, while every
> field it records is still valid.
