Subject: Re: [PATCH 6.18.y] can: isotp: fix timer drain order, wakeup handling and tx_gen ordering
Date: Thu, 6 Aug 2026 07:36:11 -0400 [thread overview]
Message-ID: <20260806021809.0018-sashal@kernel.org> (raw)
In-Reply-To: <20260805125414.30592-1-socketcan@hartkopp.net>
The skb->hash echo tag doesn't work here. isotp_set_skb_uid() is only
called from the TX paths, never from isotp_send_fc(), so FC loopback
echoes arrive with skb->hash == 0 and alias the so->cfecho == 0 "nothing
pending" sentinel. Upstream is fine because d4fb6514ff8e stamps the UID
in can_receive(), but that commit isn't on 6.18.

Thanks,
