DECnet: don't leak uninitialized stack byte

2010-12-09T21:24:19Z

commit 3c6f27bf33052ea6ba9d82369fb460726fb779c0 upstream. A single uninitialized padding byte is leaked to userspace. Signed-off-by: Dan Rosenberg Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

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

sock: add net to prot->enter_memory_pressure callback

2008-07-17T03:28:10Z

The tcp_enter_memory_pressure calls NET_INC_STATS, but doesn't have where to get the net from. I decided to add a sk argument, not the net itself, only to factor all the required sock_net(sk) calls inside the enter_memory_pressure callback itself.

decnet: Remove SOCK_SLEEP_{PRE,POST} usage.

2008-06-17T08:06:01Z

Just expand the wait sequence. And as a nice side-effect the timeout is respected now. Signed-off-by: David S. Miller

[NET] NETNS: Omit sock->sk_net without CONFIG_NET_NS.

2008-03-25T19:39:55Z

Introduce per-sock inlines: sock_net(), sock_net_set() and per-inet_timewait_sock inlines: twsk_net(), twsk_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] 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

[ATALK/DECNET]: Use seq_open_private in appletalk and decnet.

2008-02-29T19:38:24Z

These two also perform manual seq_open_private, so patch them both at once. But unlike ATM code, these already use the seq_release_private, so I splitted this patch from the previous one. Signed-off-by: Pavel Emelyanov Acked-by: Arnaldo Carvalho de Melo Signed-off-by: David S. Miller

[DECNET]: Use htons() where appropriate.

[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]: 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.
