2008-01-28[VLAN]: Simplify vlan unregistrationPatrick McHardy
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.

2008-01-28[VLAN]: Clean up unregister_vlan_devPatrick McHardy
Save two levels of indentation by aborting on error conditions, remove unnecessary initialization to NULL and remove two obvious comments. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-01-28[VLAN]: Clean up initialization codePatrick McHardy
- move module init/exit functions to end of file, remove some now unnecessary forward declarations - remove some obvious comments - clean up proc init function and move a proc-related printk there Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-01-28[VLAN]: Remove non-implemented ioctlsPatrick McHardy
The GET_VLAN_INGRESS_PRIORITY_CMD/GET_VLAN_EGRESS_PRIORITY_CMD ioctls are not implemented and won't be, new functionality will be added to the netlink interface. Remove the code and make the ioctl handler return -EOPNOTSUPP for unknown commands instead of -EINVAL. Also remove a comment about passing unknown commands to the underlying device, that doesn't make any sense since its a VLAN specific ioctl and if its not implemented here, its implemented nowhere.

2008-01-28[VLAN]: Clean up debugging and printksPatrick McHardy
- use pr_* functions and common prefix for non-device related messages - remove VLAN_ printk levels - kill lots of useless debugging statements - remove a few unnecessary printks like for double VID registration (already returns -EEXIST) and kill of a number of unnecessary checks in vlan_proc_{add,rem}_dev() that are already performed by the caller Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2008-01-28[ETHER]: Bring back MAC_FMTPatrick McHardy
The print_mac function is not very suitable for debugging printks in performance critical paths since without ifdefs it will always get called.

2008-01-28[NET_SCHED]: sch_ingress: remove useless printkPatrick McHardy
The printk about ingress qdisc registration error can't be triggered under normal circumstances. Since register_qdisc only fails for two identical registrations, the only way to trigger it is by loading the sch_ingress modules multiple times under different names, in which case we already return -EEXIST to userspace.

2008-01-28[IrDA]: Frame length validation.Robie Basak
When using a stir4200-based USB adaptor to talk to a device that uses an mcp2150, the stir4200 sometimes drops an incoming frame causing the mcp2150 to try and retransmit the lost frame. In this combination, the next frame received from the mcp2150 is often invalid - either an empty i:rsp or an IrCOMM i:rsp with an invalid clen. These corner cases are now checked.

2008-01-28[NETNS]: Namespace stop vs 'ip r l' race.Denis V. Lunev
During network namespace stop process kernel side netlink sockets belonging to a namespace should be closed. They should not prevent namespace to stop, so they do not increment namespace usage counter. Though this counter will be put during last sock_put. The raplacement of the correct netns for init_ns solves the problem only partial as socket to be stoped until proper stop is a valid netlink kernel socket and can be looked up by the user processes. This is not a problem until it resides in initial namespace (no processes inside this net), but this is not true for init_net. So, hold the referrence for a socket, remove it from lookup tables and only after that change namespace and perform a last put. Signed-off-by: Denis V.

2008-01-28[NETNS]: Memory leak on network namespace stop.Denis V. Lunev

2008-01-28[NETNS]: Double free in netlink_release.Denis V. Lunev
Netlink protocol table is global for all namespaces. Some netlink protocols have been virtualized, i.e. they have per/namespace netlink socket. This difference can easily lead to double free if more than 1 namespace is started. Count the number of kernel netlink sockets to track that this table is not used any more. Signed-off-by: Denis V.

2008-01-28[IPV6]: Fix ip6_frag ctlDaniel Lezcano
Alexey Dobriyan reported an oops when unsharing the network indefinitely inside a loop. This is because the ip6_frag is not per namespace while the ctls are. That happens at the fragment timer expiration: inet_frag_secret_rebuild function is called and this one restarts the timer using the value stored inside the sysctl field. "mod_timer(&f->secret_timer, now + f->ctl->secret_interval);" When the network is unshared, ip6_frag.ctl is initialized with the new sysctl instances, but ip6_frag has only one instance. A race in this case will appear because f->ctl can be modified during the read access in the timer callback. Until the ip6_frag is not per namespace, I discard the assignation to the ctl field of ip6_frags in ip6_frag_sysctl_init when the network namespace is not the init net.

2008-01-28net: NEWEMAC: Fix problem with mtu > 4080 on non TAH equipped 4xx PPC'sStefan Roese
Currently, all non TAH equipped 4xx PPC's call emac_start_xmit() upon xmit. This routine doesn't check if the frame length exceeds the max. MAL buffer size. This patch now changes the driver to call emac_start_xmit_sg() on all GigE platforms and not only the TAH equipped ones (440GX). This enables an MTU of 9000 instead 4080.
