[IPV4]: Always set fl.proto in ip_route_newports

2006-02-01T01:35:35+00:00

ip_route_newports uses the struct flowi from the struct rtable returned
by ip_route_connect for the new route lookup and just replaces the port
numbers if they have changed. If an IPsec policy exists which doesn't match
port 0 the struct flowi won't have the proto field set and no xfrm lookup
is done for the changed ports.

[NETFILTER]: Handle NAT in IPsec policy checks

2006-01-07T20:57:37+00:00

Handle NAT of decapsulated IPsec packets by reconstructing the struct flowi
of the original packet from the conntrack information for IPsec policy
checks.

[NETFILTER]: Keep conntrack reference until IPsec policy checks are done

2006-01-07T20:57:36+00:00

Keep the conntrack reference until policy checks have been performed for
IPsec NAT support. The reference needs to be dropped before a packet is
queued to avoid having the conntrack module unloadable.

[INET_SOCK]: Move struct inet_sock & helper functions to net/inet_sock.h

2006-01-03T21:11:21+00:00

To help in reducing the number of include dependencies, several files were
touched as they were getting needed headers indirectly for stuff they use.

Thanks also to Alan Menegotto for pointing out that net/dccp/proto.c had
linux/dccp.h include twice.

[SOCK]: Introduce sk_receive_skb

2006-01-03T21:11:19+00:00

Its common enough to to justify that, TCP still can't use it as it has the
prequeueing stuff, still to be made generic in the not so distant future :-)

[IP_SOCKGLUE]: Remove most of the tcp specific calls

2006-01-03T21:10:58+00:00

As DCCP needs to be called in the same spots.

Now we have a member in inet_sock (is_icsk), set at sock creation time from
struct inet_protosw->flags (if INET_PROTOSW_ICSK is set, like for TCP and
DCCP) to see if a struct sock instance is a inet_connection_sock for places
like the ones in ip_sockglue.c (v4 and v6) where we previously were looking if
sk_type was SOCK_STREAM, that is insufficient because we now use the same code
for DCCP, that has sk_type SOCK_DCCP.

[INET]: Generalise tcp_v4_hash_connect

2006-01-03T21:10:55+00:00

Renaming it to inet_hash_connect, making it possible to ditch
dccp_v4_hash_connect and share the same code with TCP instead.

[TWSK]: Introduce struct timewait_sock_ops

2006-01-03T21:10:54+00:00

So that we can share several timewait sockets related functions and
make the timewait mini sockets infrastructure closer to the request
mini sockets one.

Next changesets will take advantage of this, moving more code out of
TCP and DCCP v4 and v6 to common infrastructure.

[DCCP]: Use reqsk_free in dccp_v4_conn_request

2006-01-03T21:10:53+00:00

Now we have the destructor (dccp_v4_reqsk_destructor) in our
request_sock_ops vtable.

[DCCP]: Prepare the AF agnostic core for the introduction of DCCPv6

2006-01-03T21:10:50+00:00

Basically exports a similar set of functions as the one exported by
the non-AF specific TCP code.

In the process moved some non-AF specific code from dccp_v4_connect to
dccp_connect_init and moved the checksum verification from
dccp_invalid_packet to dccp_v4_rcv, so as to use it in dccp_v6_rcv
too.
