[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.

[IPV4]: inet_init() -> fs_initcall

Convert inet_init to an fs_initcall to make sure its called before any
device driver's initcall.

[NET]: Identation & other cleanups related to compat_[gs]etsockopt cset

No code changes, just tidying up, in some cases moving EXPORT_SYMBOLs
to just after the function exported, etc.

[NET]: {get|set}sockopt compatibility layer

2006-03-21T06:45:21+00:00

This patch extends {get|set}sockopt compatibility layer in order to
move protocol specific parts to their place and avoid huge universal
net/compat.c file in the future.

[NET]: Add a dev_ioctl() fallback to sock_ioctl()

2006-01-03T22:18:33+00:00

Currently all network protocols need to call dev_ioctl as the default
fallback in their ioctl implementations.  This patch adds a fallback
to dev_ioctl to sock_ioctl if the protocol returned -ENOIOCTLCMD.
This way all the procotol ioctl handlers can be simplified and we don't
need to export dev_ioctl.

[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.
