raw: Restore /proc/net/raw correct behavior

2008-06-17T00:03:32+00:00

I just noticed "cat /proc/net/raw" was buggy, missing '\n' separators.

I believe this was introduced by commit 8cd850efa4948d57a2ed836911cfd1ab299e89c6 
([RAW]: Cleanup IPv4 raw_seq_show.)

This trivial patch restores correct behavior, and applies to current 
Linus tree (should also be applied to stable tree as well.)

raw: Raw socket leak.

2008-06-04T22:16:12+00:00

The program below just leaks the raw kernel socket

int main() {
        int fd = socket(PF_INET, SOCK_RAW, IPPROTO_UDP);
        struct sockaddr_in addr;

        memset(&addr, 0, sizeof(addr));
        inet_aton("127.0.0.1", &addr.sin_addr);
        addr.sin_family = AF_INET;
        addr.sin_port = htons(2048);
        sendto(fd,  "a", 1, MSG_MORE, &addr, sizeof(addr));
        return 0;
}

Corked packet is allocated via sock_wmalloc which holds the owner socket,
so one should uncork it and flush all pending data on close. Do this in the
same way as in UDP.

net: Allow netdevices to specify needed head/tailroom

2008-05-13T03:48:31+00:00

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)

[SOCK][NETNS]: Add a struct net argument to sock_prot_inuse_add and _get.

2008-04-01T02:41:46+00:00

This counter is about to become per-proto-and-per-net, so we'll need 
two arguments to determine which cell in this "table" to work with.

All the places, but proc already pass proper net to it - proc will be
tuned a bit later.

Some indentation with spaces in proc files is done to keep the file
coding style consistent.

[SOCK]: Drop inuse pcounter from struct proto (v2).

2008-03-28T23:39:33+00:00

An uppercut - do not use the pcounter on struct proto.

[NET] NETNS: Omit namespace comparision without CONFIG_NET_NS.

2008-03-25T19:40:00+00:00

Introduce an inline net_eq() to compare two namespaces.
Without CONFIG_NET_NS, since no namespace other than &init_net
exists, it is always 1.

We do not need to convert 1) inline vs inline and
2) inline vs &init_net comparisons.

[NET] NETNS: Omit seq_net_private->net without CONFIG_NET_NS.

2008-03-25T19:39:56+00:00

Without CONFIG_NET_NS, no namespace other than &init_net exists,
no need to store net in seq_net_private.

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

2008-03-25T19:39:55+00:00

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.

Without CONFIG_NET_NS, no namespace other than &init_net exists.
