[IPV4]: struct ip_options annotations

2006-09-29T01:01:53+00:00

->faddr is net-endian; annotated as such, variables inferred to be net-endian
annotated.

[IPV4]: Fix order in inet_init failure path.

2006-09-29T01:01:48+00:00

This is just a minor buglet I came across by accident - when inet_init
fails to register raw_prot, it jumps to out_unregister_udp_proto which
should unregister UDP _and_ TCP.

[IPV4]: ip_route_connect() ipv4 address arguments annotated

2006-09-29T00:54:06+00:00

annotated address arguments (port number left alone for now); ditto
for inferred net-endian variables in callers.

[NET/IPV4/IPV6]: Change some sysctl variables to __read_mostly

2006-09-22T21:55:03+00:00

Change net/core, ipv4 and ipv6 sysctl variables to __read_mostly.

Couldn't actually measure any performance increase while testing (.3%
I consider noise), but seems like the right thing to do.

[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

[NET] gso: Fix up GSO packets with broken checksums

2006-07-08T20:34:56+00:00

Certain subsystems in the stack (e.g., netfilter) can break the partial
checksum on GSO packets.  Until they're fixed, this patch allows this to
work by recomputing the partial checksums through the GSO mechanism.

Once they've all been converted to update the partial checksum instead of
clearing it, this workaround can be removed.

[NET]: Verify gso_type too in gso_segment

2006-07-04T02:38:35+00:00

We don't want nasty Xen guests to pass a TCPv6 packet in with gso_type set
to TCPv4 or even UDP (or a packet that's both TCP and UDP).

[NET]: Added GSO header verification

2006-06-29T23:57:53+00:00

When GSO packets come from an untrusted source (e.g., a Xen guest domain),
we need to verify the header integrity before passing it to the hardware.

Since the first step in GSO is to verify the header, we can reuse that
code by adding a new bit to gso_type: SKB_GSO_DODGY.  Packets with this
bit set can only be fed directly to devices with the corresponding bit
NETIF_F_GSO_ROBUST.  If the device doesn't have that bit, then the skb
is fed to the GSO engine which will allow the packet to be sent to the
hardware if it passes the header check.

This patch changes the sg flag to a full features flag.  The same method
can be used to implement TSO ECN support.  We simply have to mark packets
with CWR set with SKB_GSO_ECN so that only hardware with a corresponding
NETIF_F_TSO_ECN can accept them.  The GSO engine can either fully segment
the packet, or segment the first MTU and pass the rest to the hardware for
further segmentation.
