This is wrong > and unnecessary. > > nf_reset() is used in the following cases: > > - when passing packets up the the socket layer, at which point we want to > release all netfilter references that might keep modules pinned while > the packet is queued. nf_trace doesn't matter anymore at this point. > > - when encapsulating or decapsulating IPsec packets. We want to continue > tracing these packets after IPsec processing. > > - when passing packets through virtual network devices. Only devices on > that encapsulate in IPv4/v6 matter since otherwise nf_trace is not > used anymore. Its not entirely clear whether those packets should > be traced after that, however we've always done that. > > - when passing packets through virtual network devices that make the > packet cross network namespace boundaries. This is the only cases > where we clearly want to reset nf_trace and is also what the > original patch intended to fix. > > Add a new function nf_reset_trace() and use it in dev_forward_skb() to > fix this properly. > > Signed-off-by: Patrick McHardy <kaber@xxxxxxxxx> I'll apply this directly because I'm trying to get a pull request out to Linus. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
