The hashtable size is really unsigned so sparse complains when you pass a signed integer. Change all uses to make it consistent. Signed-off-by:

The TCPMSS target in Xtables should consider the MTU of the reverse route on forwarded packets as part of the path MTU. Point in case: IN=ppp0, OUT=eth0. MSS set to 1460 in spite of MTU of ppp0 being 1392. Signed-off-by:

When number of entries exceeds number of initial entries, foo-tables code will pin table module. But during table unregister on netns stop, that additional pin was forgotten. Signed-off-by:

Now it's possible to list and manipulate per-netns ip6tables rules. Filtering decisions are based on init_net's table so far. P.S.: remove init_net check in inet6_create() to see the effect Signed-off-by:

* Propagate netns from userspace down to xt_find_table_lock() * Register ip6 tables in netns (modules still use init_net) Signed-off-by:

Now, iptables show and configure different set of rules in different netnss'. Filtering decisions are still made by consulting only init_net's set. Changes are identical except naming so no splitting. P.S.: one need to remove init_net checks in nf_sockopt.c and inet_create() to see the effect. Signed-off-by: -

Typical table module registers xt_table structure (i.e. packet_filter) and link it to list during it. We can't use one template for it because corresponding list_head will become corrupted. We also can't unregister with template because it wasn't changed at all and thus doesn't know in which list it is. So, we duplicate template at the very first step of table registration. Table modules will save it for use during unregistration time and actual filtering. Do it at once to not screw bisection. P.S.: renaming i.e. packet_filter => __packet_filter is temporary until full netnsization of table modules is done. Signed-off-by: -

In fact all we want is per-netns set of rules, however doing that will unnecessary complicate routines such as ipt_hook()/ipt_do_table, so make full xt_table array per-netns. Every user stubbed with init_net for a while. Signed-off-by:

Before the removal of the deferred output hooks, netoutdev was used in case of VLANs on top of a bridge to store the VLAN device, so the deferred hooks would see the correct output device. This isn't necessary anymore since we're calling the output hooks for the correct device directly in the IP stack. Signed-off-by:

NewReno should add cnt per skb (as with FACK) instead of depending on SACKED_ACKED bits which won't be set with it at all. Effectively, NewReno should always exists after the first iteration anyway (or immediately if there's already head in lost_out. This was fixed earlier in net-2.6.25 but got reverted among other stuff and I didn't notice that this is still necessary (actually wasn't even considering this case while trying to figure out the reports because I lived with different kind of code than it in reality was). This should solve the WARN_ONs in TCP code that as a result of this triggered multiple times in every place we check for this invariant.

The comment about "race free view of the set of network namespaces" was a bit hasty. Look (there even can be only one CPU, as discovered by Alexey Dobriyan and Denis Lunev): put_net() if (atomic_dec_and_test(&net->refcnt)) /* true */ __put_net(net); queue_work(...); /* * note: the net now has refcnt 0, but still in * the global list of net namespaces */ == re-schedule == register_pernet_subsys(&some_ops); register_pernet_operations(&some_ops); (*some_ops)->init(net); /* * we call netlink_kernel_create() here * in some places */ netlink_kernel_create(); sk_alloc(); get_net(net); /* refcnt = 1 */ /* * now we drop the net refcount not to * block the net namespace exit in the * future (or this can be done on the * error path) */ put_net(sk->sk_net); if (atomic_dec_and_test(&...)) /* * true. BOOOM! The net is * scheduled for release twice */ When thinking on this problem, I decided, that getting and putting the net in init callback is wrong. If some init callback needs to have a refcount-less reference on the struct net, _it_ has to be careful himself, rather than relying on the infrastructure to handle this correctly. In case of netlink_kernel_create(), the problem is that the sk_alloc() gets the given namespace, but passing the info that we don't want to get it inside this call is too heavy. Instead, I propose to crate the socket inside an init_net namespace and then re-attach it to the desired one right after the socket is created. After doing this, we also have to be careful on error paths not to drop the reference on the namespace, we didn't get the one on. Signed-off-by:Pavel Emelyanov <xemul@openvz.org> Acked-by:
