This one got renamed, complicating the merge a bit...this should restore it to its intended state. Signed-off-by:John W. Linville <linville@tuxdriver.com>

This change is necessary to allow cwnd to grow during persistent reordering. Cwnd moderation is applied when in the disorder state and an ack that fills the hole comes in. If the hole was greater than 3 packets, but less than tp->reordering, cwnd will shrink when it should not have. Signed-off-by:

The alloc_netdev_mq() tries to produce 32-bytes alignment for both the net_device itself and its private data. The second alignment is achieved by adding the NETDEV_ALIGN_CONST to the whole size of the memory to be allocated. However, for those devices that do not need the private area, this addition just makes the net_device weight 1024 + 32 = 1068 bytes, i.e. consume twice as much memory. Since loopback device is such (sizeof_priv == 0 for it), and each net namespace creates one, this can save a noticeable amount of memory for kernel with net namespaces turned on. After this set the lo device is actually allocated from a size-1024 kmem cache on i386 box even with NETPOLL and WIRELESS_EXT turned on. Signed-off-by:

dev_set_net is called for - just allocated devices - devices moving from one namespace to another release_net has proper check inside to distinguish these cases. Signed-off-by:

Protocol control sockets and netlink kernel sockets should not prevent the namespace stop request. They are initialized and disposed in a special way by sk_change_net/sk_release_kernel. Signed-off-by:

Make release_net/hold_net noop for performance-hungry people. This is a debug staff and should be used in the debug mode only. Add check for net != NULL in hold/release calls. This will be required later on. [ Added minor simplifications suggested by Brian Haley. -DaveM ] Signed-off-by:

And no need in some IPPROTO_XXX enabling, since ipv6 code doesn't have any filtering. So, just set proper net and mark device with NETNS_LOCAL. Signed-off-by:

All the ip_route_output_key(), dev_get_by_...() and ipv6_chk_addr() calls are now stubbed with init_net. Fortunately, all the places already have where to get the proper net from. Signed-off-by:

Move hashes in the struct ip6_tnl_net, replace tnls_xxx[] with ip6n->tnlx_xxx[] and handle init and exit appropriately. Signed-off-by:

Pavel Emelyanov authored
All the code, that reference it already has the ip6_tnl_net pointer, so s/ip6_fb_tnl_dev/ip6n->fb_tnl_dev/ and move creation/releasing code into net init/exit ops. Signed-off-by:

Calls to ip6_tnl_lookup were stubbed with init_net - give them a proper one. Signed-off-by:

As for the IPIP tunnel, there are some ip_route_output_key() calls in there that require a proper net so give one to them. And a proper net for the __get_dev_by_index hanging around. Signed-off-by:

Everything is prepared for this change now. Create on in init callback, use it over the code and destroy on net exit. Signed-off-by:

This is the part#2 of the patch #2 - get the proper net for these functions. This change in a separate patch in order not to get lost in a large previous patch. Signed-off-by:

The fallback device and hashes are to become per-net, but many code doesn't have anything to get the struct net pointer from. So pass the proper net there with an extra argument. Signed-off-by:

There are some ip_route_output_key() calls in there that require a proper net so give one to them. Besides - give a proper net to a single __get_dev_by_index call in ipip_tunnel_bind_dev(). Signed-off-by:

Either net or ipip_net already exists in all the required places, so just use one. Besides, tune net_init and net_exit calls to respectively initialize the hashes and destroy devices. Signed-off-by:

The hashes of tunnels will be per-net too, so prepare all the functions that uses them for this change by adding an argument. Use init_net temporarily in places, where the net does not exist explicitly yet. Signed-off-by:
