[VLAN]: Simplify vlan unregistration

2008-01-28T23:08:31+00:00

Keep track of the number of VLAN devices in a vlan group. This allows
to have the caller sense when the group is going to be destroyed and
stop using it, which in turn allows to remove the wrapper around
unregister_vlan_dev for the NETDEV_UNREGISTER notifier and avoid
iterating over all possible VLAN ids whenever a device in unregistered.

Also fix what looks like a use-after-free (but is actually safe since
we're holding the RTNL), the real_dev reference should not be dropped
while we still use it.

[VLAN]: Kill useless VLAN_NAME define

2008-01-28T23:08:25+00:00

The only user already includes __FUNCTION__ (vlan_proto_init) in the
output, which is enough to identify what the message is about.

[VLAN]: Clean up vlan_hdr/vlan_ethhdr structs

2008-01-28T23:08:24+00:00

Fix 3 space indentation and some overly long lines by moving the
comments to a kdoc structure description.

[VLAN]: Remove unnecessary structure declarations

2008-01-28T23:08:23+00:00

- struct packet_type is not used
- struct vlan_group is declared later in the file before the first use
- struct net_device is not needed since netdevice.h is included
- struct vlan_collection does not exist
- struct vlan_dev_info is declared later in the file before the first use

[VLAN]: Avoid expensive divides

2008-01-28T23:01:06+00:00

We can avoid divides (as seen with CONFIG_CC_OPTIMIZE_FOR_SIZE=y on
x86) changing vlan_group_get_device()/vlan_group_set_device() id
parameter from signed to unsigned.

[NET]: Make the device list and device lookups per namespace.

2007-10-10T23:49:10+00:00

This patch makes most of the generic device layer network
namespace safe.  This patch makes dev_base_head a
network namespace variable, and then it picks up
a few associated variables.  The functions:
dev_getbyhwaddr
dev_getfirsthwbytype
dev_get_by_flags
dev_get_by_name
__dev_get_by_name
dev_get_by_index
__dev_get_by_index
dev_ioctl
dev_ethtool
dev_load
wireless_process_ioctl

were modified to take a network namespace argument, and
deal with it.

vlan_ioctl_set and brioctl_set were modified so their
hooks will receive a network namespace argument.

So basically anthing in the core of the network stack that was
affected to by the change of dev_base was modified to handle
multiple network namespaces.  The rest of the network stack was
simply modified to explicitly use &init_net the initial network
namespace.  This can be fixed when those components of the network
stack are modified to handle multiple network namespaces.

For now the ifindex generator is left global.

Fundametally ifindex numbers are per namespace, or else
we will have corner case problems with migration when
we get that far.

At the same time there are assumptions in the network stack
that the ifindex of a network device won't change.  Making
the ifindex number global seems a good compromise until
the network stack can cope with ifindex changes when
you change namespaces, and the like.
