[TUNTAP]: Fix wrong debug message.

2007-12-27T03:36:34+00:00

This is a trivial fix of debug message.
When a persist flag is set, the message should say "enabled".

[NET]: Introduce and use print_mac() and DECLARE_MAC_BUF()

This is nicer than the MAC_FMT stuff.

[NET] drivers/net: statistics cleanup #1 -- save memory and shrink code

2007-10-10T23:51:16+00:00

We now have struct net_device_stats embedded in struct net_device,
and the default ->get_stats() hook does the obvious thing for us.

Run through drivers/net/* and remove the driver-local storage of
statistics, and driver-local ->get_stats() hook where applicable.

This was just the low-hanging fruit in drivers/net; plenty more drivers
remain to be updated.

[NET]: Nuke SET_MODULE_OWNER macro.

2007-10-10T23:51:13+00:00

It's been a useless no-op for long enough in 2.6 so I figured it's time to
remove it.  The number of people that could object because they're
maintaining unified 2.4 and 2.6 drivers is probably rather small.

[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.

[NET]: Allow group ownership of TUN/TAP devices.

2007-07-11T05:16:42+00:00

Introduce a new syscall TUNSETGROUP for group ownership setting of tap
devices. The user now is allowed to send packages if either his euid or
his egid matches the one specified via tunctl (via -u or -g
respecitvely). If both, gid and uid, are set via tunctl, both have to
match.

[NET] tun/tap: fixed hw address handling

2007-04-26T08:00:55+00:00

Fixed tun/tap driver's handling of hw addresses.  The hw address is stored
in both the net_device.dev_addr and tun.dev_addr fields.  These fields were
not kept synchronized, and in fact weren't even initialized to the same
value.  Now during both init and when performing SIOCSIFHWADDR on the tun
device these values are both updated.  However, if SIOCSIFHWADDR is
performed on the net device directly (for instance, setting the hw address
using ifconfig), the tun device does not get updated.  Perhaps the
tun.dev_addr field should be removed completely at some point, as it is
redundant and net_device.dev_addr can be used anywhere it is used.

[SK_BUFF]: Introduce skb_copy_from_linear_data{_offset}

2007-04-26T05:28:23+00:00

To clearly state the intent of copying from linear sk_buffs, _offset being a
overly long variant but interesting for the sake of saving some bytes.

[SK_BUFF]: Introduce skb_reset_mac_header(skb)

2007-04-26T05:24:32+00:00

For the common, open coded 'skb->mac.raw = skb->data' operation, so that we can
later turn skb->mac.raw into a offset, reducing the size of struct sk_buff in
64bit land while possibly keeping it as a pointer on 32bit.

This one touches just the most simple case, next will handle the slightly more
"complex" cases.
