Date: Wed, 07 Oct 2026 18:43:26 +0000 [thread overview]

In-Reply-To: <20261007-nb-net-selftest-shared-net-v1-2-458369bfa1ba@tipi-net.de>
> The loopback hook gets a shared skb when another ETH_P_IP handler is
> bound to the device. skb_unshare() does not unshare it, so
> skb_linearize() on a non-linear frame hits BUG_ON(skb_shared()).
>
> Use skb_share_check() instead.
