Subject: Re: [PATCH net v2 1/3] openvswitch: only skb_tx_error() a packet we are about to drop
Date: Tue, 18 Aug 2026 03:30:08 +0900 [thread overview]
Message-ID: <20260817183009.357-1-payload.jang@gmail.com> (raw)
In-Reply-To: <3766FAA3-D915-4ECD-B51D-DCF390F3C03C@doyensec.com>
Hi Norbert,
I independently tested this patch as part of the v2 series using a
separate, non-destructive page-cache canary reproducer.
The test exercised a failed nonterminal OVS USERSPACE action followed by
forwarding:
userspace(pid=1),2
Before the fix, the root-owned read-only page-cache canary changed. With
v2 applied, the canary remained unchanged. No kernel warning, oops, or
panic was observed.
Tested-by: Jongmin Jang <payload.jang@gmail.com>
Best regards,
Jongmin Jang
