netns: Use net_eq() to compare net-namespaces for optimization.

2008-07-20T05:34:43Z

Without CONFIG_NET_NS, namespace is always &init_net. Compiler will be able to omit namespace comparisons with this patch. Signed-off-by: YOSHIFUJI Hideaki Signed-off-by: David S. Miller

econet: Use sock_orphan() instead of open-coded (and buggy) variant.

2008-06-17T10:01:47Z

It doesn't grab the sk_callback_lock, it doesn't NULL out the sk->sk_sleep waitqueue pointer, etc. Signed-off-by: David S. Miller

net: Allow netdevices to specify needed head/tailroom

2008-05-13T03:48:31Z

This patch adds needed_headroom/needed_tailroom members to struct net_device and updates many places that allocate sbks to use them. Not all of them can be converted though, and I'm sure I missed some (I mostly grepped for LL_RESERVED_SPACE) Signed-off-by: Johannes Berg Signed-off-by: David S. Miller

[NET] NETNS: Omit net_device->nd_net without CONFIG_NET_NS.

2008-03-25T19:39:53Z

Introduce per-net_device inlines: dev_net(), dev_net_set(). Without CONFIG_NET_NS, no namespace other than &init_net exists. Let's explicitly define them to help compiler optimizations. Signed-off-by: YOSHIFUJI Hideaki

[NET]: Convert init_timer into setup_timer

2008-01-28T22:53:35Z

Many-many code in the kernel initialized the timer->function and timer->data together with calling init_timer(timer). There is already a helper for this. Use it for networking code. The patch is HUGE, but makes the code 130 lines shorter (98 insertions(+), 228 deletions(-)). Signed-off-by: Pavel Emelyanov Acked-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

[NET]: Forget the zero_it argument of sk_alloc()

2007-11-01T07:39:31Z

Finally, the zero_it argument can be completely removed from the callers and from the function prototype. Besides, fix the checkpatch.pl warnings about using the assignments inside if-s. This patch is rather big, and it is a part of the previous one. I splitted it wishing to make the patches more readable. Hope this particular split helped.

[NET]: Wrap netdevice hardware header creation.

2007-10-10T23:52:50Z

Add inline for common usage of hardware header creation, and fix bug in IPV6 mcast where the assumption about negative return is an errno. Negative return from hard_header means not enough space was available,(ie -N bytes). Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

[NET]: Make the device list and device lookups per namespace.

2007-10-10T23:49:10Z

This patch makes most of the generic device layer network namespace safe. This patch makes dev_base_head a network namespace variable, and then it picks up a few associated variables. The functions: dev_getbyhwaddr dev_getfirsthwbytype dev_get_by_flags dev_get_by_name __dev_get_by_name dev_get_by_index __dev_get_by_index dev_ioctl dev_ethtool dev_load wireless_process_ioctl were modified to take a network namespace argument, and deal with it. vlan_ioctl_set and brioctl_set were modified so their hooks will receive a network namespace argument. So basically anthing in the core of the network stack that was affected to by the change of dev_base was modified to handle multiple network namespaces. The rest of the network stack was simply modified to explicitly use &init_net the initial network namespace. This can be fixed when those components of the network stack are modified to handle multiple network namespaces. For now the ifindex generator is left global. Fundametally ifindex numbers are per namespace, or else we will have corner case problems with migration when we get that far. At the same time there are assumptions in the network stack that the ifindex of a network device won't change. Making the ifindex number global seems a good compromise until the network stack can cope with ifindex changes when you change namespaces, and the like. Signed-off-by: Eric W.

[NET]: Make device event notification network namespace safe

2007-10-10T23:49:09Z

Every user of the network device notifiers is either a protocol stack or a pseudo device. If a protocol stack that does not have support for multiple network namespaces receives an event for a device that is not in the initial network namespace it quite possibly can get confused and do the wrong thing. To avoid problems until all of the protocol stacks are converted this patch modifies all netdev event handlers to ignore events on devices that are not in the initial network namespace. As the rest of the code is made network namespace aware these checks can be removed. Signed-off-by: Eric W. Biederman Signed-off-by: David S. Miller

[NET]: Make packet reception network namespace safe

2007-10-10T23:49:08Z

This patch modifies every packet receive function registered with dev_add_pack() to drop packets if they are not from the initial network namespace. This should ensure that the various network stacks do not receive packets in a anything but the initial network namespace until the code has been converted and is ready for them.
