[IPV6]: Fix address/interface handling in UDP and DCCP, according to the scoping architecture.

2006-11-22T01:41:56+00:00

TCP and RAW do not have this issue.  Closes Bug #7432.

[UDP]: Fix MSG_PROBE crash

2006-10-04T07:31:00+00:00

UDP tracks corking status through the pending variable.  The
IP layer also tracks it through the socket write queue.  It
is possible for the two to get out of sync when MSG_PROBE is
used.

This patch changes UDP to check the write queue to ensure
that the two stay in sync.

[UDP6]: Fix flowi clobbering

2006-10-04T07:30:59+00:00

The udp6_sendmsg function uses a shared buffer to store the
flow without taking any locks.  This leads to races with SMP.
This patch moves the flowi object onto the stack.

[UDP]: Unify UDPv4 and UDPv6 ->get_port()

2006-09-22T22:18:21+00:00

This patch creates one common function which is called by
udp_v4_get_port() and udp_v6_get_port(). As a result,
  * duplicated code is removed
  * udp_port_rover and local port lookup can now be removed from udp.h
  * further savings follow since the same function will be used by UDP-Litev4
    and UDP-Litev6

In contrast to the patch sent in response to Yoshifujis comments
(fixed by this variant), the code below also removes the
EXPORT_SYMBOL(udp_port_rover), since udp_port_rover can now remain
local to net/ipv4/udp.c.

[NET]: Replace CHECKSUM_HW by CHECKSUM_PARTIAL/CHECKSUM_COMPLETE

2006-09-22T21:53:53+00:00

Replace CHECKSUM_HW by CHECKSUM_PARTIAL (for outgoing packets, whose
checksum still needs to be completed) and CHECKSUM_COMPLETE (for
incoming packets, device supplied full checksum).

Patch originally from Herbert Xu, updated by myself for 2.6.18-rc3.

[MLSXFRM]: Add flow labeling

2006-09-22T21:53:27+00:00

This labels the flows that could utilize IPSec xfrms at the points the
flows are defined so that IPSec policy and SAs at the right label can
be used.

The following protos are currently not handled, but they should
continue to be able to use single-labeled IPSec like they currently
do.

ipmr
ip_gre
ipip
igmp
sit
sctp
ip6_tunnel (IPv6 over IPv6 tunnel device)
decnet

[IPV6]: Audit all ip6_dst_lookup/ip6_dst_store calls

2006-08-02T20:38:14+00:00

The current users of ip6_dst_lookup can be divided into two classes:

1) The caller holds no locks and is in user-context (UDP).
2) The caller does not want to lookup the dst cache at all.

The second class covers everyone except UDP because most people do
the cache lookup directly before calling ip6_dst_lookup.  This patch
adds ip6_sk_dst_lookup for the first class.

Similarly ip6_dst_store users can be divded into those that need to
take the socket dst lock and those that don't.  This patch adds
__ip6_dst_store for those (everyone except UDP/datagram) that don't
need an extra lock.
