2010-03-07Driver core: Constify struct sysfs_ops in struct kobj_typeEmese Revfy2-2/+2
Constify struct sysfs_ops. This is part of the ops structure constification effort started by Arjan van de Ven et al. Benefits of this constification: * prevents modification of data that is shared (referenced) by many other structure instances at runtime * detects/prevents accidental (but not intentional) modification attempts on archs that enforce read-only kernel data at runtime * potentially better optimized code as the compiler can assume that the const data cannot be changed * the compiler/linker move const data into .rodata and therefore exclude them from false sharing Signed-off-by: Emese Revfy <re.emese@gmail.com> Acked-by: David Teigland <teigland@redhat.com> Acked-by: Matt Domsch <Matt_Domsch@dell.com> Acked-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Acked-by: Hans J.

2010-03-07driver-core: Add attribute argument to class_attribute show/storeAndi Kleen4-4/+12
Passing the attribute to the low level IO functions allows all kinds of cleanups, by sharing low level IO code without requiring an own function for every piece of data. Also drivers can extend the attributes with own data fields and use that in the low level function. This makes the class attributes the same as sysdev_class attributes and plain attributes. This will allow further cleanups in drivers. Full tree sweep converting all users. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2010-03-06nodemask.h: remove macro any_online_nodeH Hartley Sweeten1-1/+1
The macro any_online_node() is prone to producing sparse warnings due to the local symbol 'node'. Since all the in-tree users are really requesting the first online node (the mask argument is either NODE_MASK_ALL or node_online_map) just use the first_online_node macro and remove the any_online_node macro since there are no users.

2010-02-28nfsd: ensure sockets are closed on errorNeil Brown1-0/+1
One the changes in commit d7979ae4a "svc: Move close processing to a single place" is: err_delete: - svc_delete_socket(svsk); + set_bit(SK_CLOSE, &svsk->sk_flags); return -EAGAIN; This is insufficient. The recvfrom methods must always call svc_xprt_received on completion so that the socket gets re-queued if there is any more work to do. This particular path did not make that call because it actually destroyed the svsk, making requeue pointless. When the svc_delete_socket was change to just set a bit, we should have added a call to svc_xprt_received, This is the problem that b0401d7253 attempted to fix, incorrectly. Signed-off-by: J.

2010-02-28bridge: Add hash elasticity/max sysfs entriesHerbert Xu3-0/+81
This patch allows the user to control the hash elasticity/max parameters. The elasticity setting does not take effect until the next new multicast group is added. At which point it is checked and if after rehashing it still can't be satisfied then snooping will be disabled. The max setting on the other hand takes effect immediately. It must be a power of two and cannot be set to a value less than the current number of multicast group entries. This is the only way to shrink the multicast hash.

2010-02-28bridge: Add multicast_snooping sysfs toggleHerbert Xu3-5/+75
This patch allows the user to disable IGMP snooping completely through a sysfs toggle. It also allows the user to reenable snooping when it has been automatically disabled due to hash collisions. If the collisions have not been resolved however the system will refuse to reenable snooping. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2010-02-28bridge: Add multicast_router sysfs entriesHerbert Xu4-14/+133
This patch allows the user to forcibly enable/disable ports as having multicast routers attached. A port with a multicast router will receive all multicast traffic. The value 0 disables it completely. The default is 1 which lets the system automatically detect the presence of routers (currently this is limited to picking up queries), and 2 means that the port will always receive all multicast traffic.

2010-02-28bridge: Add multicast forwarding functionsHerbert Xu2-0/+82
This patch adds code to perform selective multicast forwarding. We forward multicast traffic to a set of ports plus all multicast router ports. In order to avoid duplications among these two sets of ports, we order all ports by the numeric value of their pointers. The two lists are then walked in lock-step to eliminate duplicates.

2010-02-28bridge: Add core IGMP snooping supportHerbert Xu4-0/+1288
This patch adds the core functionality of IGMP snooping support without actually hooking it up. So this patch should be a no-op as far as the bridge's external behaviour is concerned. All the new code and data is controlled by the Kconfig option BRIDGE_IGMP_SNOOPING. A run-time toggle is also available. The multicast switching is done using an hash table that is lockless on the read-side through RCU. On the write-side the new multicast_lock is used for all operations. The hash table supports dynamic growth/rehashing. The hash table will be rehashed if any chain length exceeds a preset limit. If rehashing does not reduce the maximum chain length then snooping will be disabled. These features may be added in future (in no particular order): * IGMPv3 source support * Non-querier router detection * IPv6 Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2010-02-28bridge: Do br_pass_frame_up after other portsHerbert Xu1-3/+3
At the moment we deliver to the local bridge port via the function br_pass_frame_up before all other ports. There is no requirement for this. For the purpose of IGMP snooping, it would be more convenient if we did the local port last. Therefore this patch rearranges the bridge input processing so that the local bridge port gets to see the packet last (if at all).

commit e8469ed959c373c2ff9e6f488aa5a14971aebe1f Author: Patrick McHardy <kaber@trash.net> Date: Tue Feb 23 20:41:30 2010 +0100 Support specifying the initial device flags when creating a device though rtnl_link. Devices allocated by rtnl_create_link() are marked as INITIALIZING in order to surpress netlink registration notifications. To complete setup, rtnl_configure_link() must be called, which performs the device flag changes and invokes the deferred notifiers if everything went well. Two examples: # add macvlan to eth0 # $ ip link add link eth0 up allmulticast on type macvlan [LINK]11: macvlan0@eth0: <BROADCAST,MULTICAST,ALLMULTI,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN link/ether 26:f8:84:02:f9:2a brd ff:ff:ff:ff:ff:ff [ROUTE]ff00::/8 dev macvlan0 table local metric 256 mtu 1500 advmss 1440 hoplimit 0 [ROUTE]fe80::/64 dev macvlan0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 0 [LINK]11: macvlan0@eth0: <BROADCAST,MULTICAST,ALLMULTI,UP,LOWER_UP> mtu 1500 link/ether 26:f8:84:02:f9:2a [ADDR]11: macvlan0 inet6 fe80::24f8:84ff:fe02:f92a/64 scope link valid_lft forever preferred_lft forever [ROUTE]local fe80::24f8:84ff:fe02:f92a via :: dev lo table local proto none metric 0 mtu 16436 advmss 16376 hoplimit 0 [ROUTE]default via fe80::215:e9ff:fef0:10f8 dev macvlan0 proto kernel metric 1024 mtu 1500 advmss 1440 hoplimit 0 [NEIGH]fe80::215:e9ff:fef0:10f8 dev macvlan0 lladdr 00:15:e9:f0:10:f8 router STALE [ROUTE]2001:6f8:974::/64 dev macvlan0 proto kernel metric 256 expires 0sec mtu 1500 advmss 1440 hoplimit 0 [PREFIX]prefix 2001:6f8:974::/64 dev macvlan0 onlink autoconf valid 14400 preferred 131084 [ADDR]11: macvlan0 inet6 2001:6f8:974:0:24f8:84ff:fe02:f92a/64 scope global dynamic valid_lft 86399sec preferred_lft 14399sec # add VLAN to eth1, eth1 is down # $ ip link add link eth1 up type vlan id 1000 RTNETLINK answers: Network is down <no events> Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2010-02-27dev: support deferring device flag change notificationsPatrick McHardy2-61/+104
Split dev_change_flags() into two functions: __dev_change_flags() to perform the actual changes and __dev_notify_flags() to invoke netdevice notifiers. This will be used by rtnl_link to defer netlink notifications until the device has been fully configured. This changes ordering of some operations, in particular: - netlink notifications are sent after all changes have been performed. As a side effect this surpresses one unnecessary netlink message when the IFF_UP and other flags are changed simultaneously. - The NETDEV_UP/NETDEV_DOWN and NETDEV_CHANGE notifiers are invoked after all changes have been performed. Their relative is unchanged. - net_dmaengine_put() is invoked before the NETDEV_DOWN notifier instead of afterwards. This should not make any difference since both RX and TX are already shut down at this point. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-02-27rtnetlink: handle rtnl_link netlink notifications manuallyPatrick McHardy2-4/+8
In order to support specifying device flags during device creation, we must be able to roll back device registration in case setting the flags fails without sending any notifications related to the device to userspace. This patch changes rollback_registered_many() and register_netdevice() to manually send netlink notifications for devices not handled by rtnl_link and allows to defer notifications for devices handled by rtnl_link until setup is complete.

2010-02-27rtnetlink: ignore NETDEV_PRE_UP notifier in rtnetlink_event()Patrick McHardy1-0/+1
Commit 3b8bcfd (net: introduce pre-up netdev notifier) added a new notifier which is run before a device is set UP for use by cfg80211. The patch missed to add the new notifier to the ignore list in rtnetlink_event(), so we currently get an unnecessary netlink notification before a device is set UP.
