net/ipv4: correct RFC 1122 section reference in comment

2008-05-08T08:11:04Z

RFC 1122 does not have a section 3.1.2.2. The requirement to silently discard datagrams with a bad checksum is in section 3.2.1.2 instead. Addresses http://bugzilla.kernel.org/show_bug.cgi?id=10611 Signed-off-by: J.H.M. Dassen (Ray) Signed-off-by: Andrew Morton Signed-off-by: David S. Miller

[IPV4]: Use NIPQUAD_FMT to format ipv4 addresses.

And use %u to format port. Signed-off-by: YOSHIFUJI Hideaki 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

[NETNS]: Drop packets in the non-initial namespace on the per/protocol basis.

2008-03-24T22:33:00Z

IP layer now can handle multiple namespaces normally. So, process such packets normally and drop them only if the transport layer is not aware about namespaces. Signed-off-by: Denis V. Lunev Signed-off-by: David S. Miller

[NETNS]: Process IP layer in the context of the correct namespace.

2008-03-24T22:31:00Z

Replace all the rest of the init_net with a proper net on the IP layer. Signed-off-by: Denis V. Lunev Signed-off-by: David S. Miller

[NETNS]: Add namespace parameter to ip_options_compile.

2008-03-24T22:29:23Z

ip_options_compile uses inet_addr_type which requires a namespace. The packet argument is optional, so parameter is the only way to obtain it. Pass the init_net there for now. Signed-off-by: Denis V. Lunev Signed-off-by: David S. Miller

[IPV4]: Always pass ip_options pointer into ip_options_compile.

2008-03-22T23:36:20Z

This makes code a bit more uniform and straigthforward. Signed-off-by: Denis V. Lunev Signed-off-by: David S. Miller

[IPV4]: Add 'rtable' field in struct sk_buff to alias 'dst' and avoid casts

2008-03-06T02:30:47Z

(Anonymous) unions can help us to avoid ugly casts. A common cast it the (struct rtable *)skb->dst one. Defining an union like : union { struct dst_entry *dst; struct rtable *rtable; }; permits to use skb->rtable in place. Signed-off-by: Eric Dumazet Signed-off-by: David S. Miller

[IPv4] RAW: Compact the API for the kernel

2008-01-28T22:54:28Z

The raw sockets functions are explicitly used from inside the kernel in two places: 1. in ip_local_deliver_finish to intercept skb-s 2. in icmp_error For this purposes many functions and even data structures, that are naturally internal for raw protocol, are exported. Compact the API to two functions and hide all the other (including hash table and rwlock) inside the net/ipv4/raw.c Signed-off-by: Pavel Emelyanov Signed-off-by: David S. Miller
