2008-07-16mib: add net to IP_INC_STATSPavel Emelyanov
All the callers already have either the net itself, or the place where to get it from. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-16ipv4: prepare net initialization for IP accountingPavel Emelyanov
Some places, that deal with IP statistics already have where to get a struct net from, but use it directly, without declaring a separate variable on the stack. So, save this net on the stack for future IP_XXX_STATS macros. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-07-16ipvs: More reliable synchronization on connection closeRumen G. Bogdanovski
This patch enhances the synchronization of the closing connections between the master and the backup director. It prevents the closed connections to expire with the 15 min timeout of the ESTABLISHED state on the backup and makes them expire as they would do on the master with much shorter timeouts.

2008-07-16ipvs: Use schedule_timeout_interruptible() instead of msleep_interruptible()Sven Wegener
So that kthread_stop() can wake up the thread and we don't have to wait one second in the worst case for the daemon to actually stop. Signed-off-by: Sven Wegener <sven.wegener@stealer.net> Acked-by: Simon Horman <horms@verge.net.au>
2008-07-16ipvs: Put backup thread on mcast socket wait queueSven Wegener
Instead of doing an endless loop with sleeping for one second, we now put the backup thread onto the mcast socket wait queue and it gets woken up as soon as we have data to process. Signed-off-by: Sven Wegener <sven.wegener@stealer.net> Acked-by: Simon Horman <horms@verge.net.au>
2008-07-16ipvs: Use kthread_run() instead of doing a double-fork via kernel_thread()Sven Wegener
This also moves the setup code out of the daemons, so that we're able to return proper error codes to user space. The current code will return success to user space when the daemon is started with an invald mcast interface. With these changes we get an appropriate "No such device" error. We longer need our own completion to be sure the daemons are actually running, because they no longer contain code that can fail and kthread_run() takes care of the rest.

2008-07-15SUNRPC: Remove the BKL from the callback functionsTrond Myklebust
Push it into those callback functions that actually need it. Note that all the NFS operations use their own locking, so don't need the BKL. Ditto for the rpcbind client. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2008-07-15SUNRPC: Support registering IPv6 interfaces with local rpcbind daemonChuck Lever
Introduce a new API to register RPC services on IPv6 interfaces to allow the NFS server and lockd to advertise on IPv6 networks. Unlike rpcb_register(), the new rpcb_v4_register() function uses rpcbind protocol version 4 to contact the local rpcbind daemon. The version 4 SET/UNSET procedures allow services to register address families besides AF_INET, register at specific network interfaces, and register transport protocols besides UDP and TCP. All of this functionality is exposed via the new rpcb_v4_register() kernel API. A user-space rpcbind daemon implementation that supports version 4 of the rpcbind protocol is required in order to make use of this new API. Note that rpcbind version 3 is sufficient to support the new rpcbind facilities listed above, but most extant implementations use version 4.

2008-07-15SUNRPC: None of rpcb_create's callers wants a privileged source portChuck Lever

2008-07-15SUNRPC: Introduce a specific rpcb_create for contacting localhostChuck Lever
Add rpcb_create_local() for use by rpcb_register() and upcoming IPv6 registration functions. Ensure any errors encountered by rpcb_create_local() are properly reported. We can also use a statically allocated constant loopback socket address instead of one allocated on the stack and initialized every time the function is called.

2008-07-15SUNRPC: Use correct XDR encoding procedure for rpcbind SET/UNSETChuck Lever
The rpcbind versions 3 and 4 SET and UNSET procedures use the same arguments as the GETADDR procedure. While definitely a bug, this hasn't been a problem so far since the kernel hasn't used version 3 or 4 SET and UNSET. But this will change in just a moment.

2008-07-14packet: support extensible, 64 bit clean mmaped ring structurePatrick McHardy
The tpacket_hdr is not 64 bit clean due to use of an unsigned long and can't be extended because the following struct sockaddr_ll needs to be at a fixed offset. Add support for a version 2 tpacket protocol that removes these limitations. Userspace can query the header size through a new getsockopt option and change the protocol version through a setsockopt option. The changes needed to switch to the new protocol version are: 1. replace struct tpacket_hdr by struct tpacket2_hdr 2. query header len and save 3. set protocol version to 2 - set up ring as usual 4. for getting the sockaddr_ll, use (void *)hdr + TPACKET_ALIGN(hdrlen) instead of (void *)hdr + TPACKET_ALIGN(sizeof(struct tpacket_hdr)) Steps 2 and 4 can be omitted if the struct sockaddr_ll isn't needed.

2008-07-14vlan: deliver packets received with VLAN acceleration to network tapsPatrick McHardy
When VLAN header stripping is used, packets currently bypass packet sockets (and other network taps) completely. For locally existing VLANs, they appear directly on the VLAN device, for unknown VLANs they are silently dropped. Add a new function netif_nit_deliver() to deliver incoming packets to all network interface taps and use it in __vlan_hwaccel_rx() to make VLAN packets visible on the underlying device.

2008-07-14vlan: Don't store VLAN tag in cbPatrick McHardy
Use a real skb member to store the skb to avoid clashes with qdiscs, which are allowed to use the cb area themselves. As currently only real devices that consume the skb set the NETIF_F_HW_VLAN_TX flag, no explicit invalidation is neccessary. The new member fills a hole on 64 bit, the skb layout changes from: __u32 mark; /* 172 4 */ sk_buff_data_t transport_header; /* 176 4 */ sk_buff_data_t network_header; /* 180 4 */ sk_buff_data_t mac_header; /* 184 4 */ sk_buff_data_t tail; /* 188 4 */ /* --- cacheline 3 boundary (192 bytes) --- */ sk_buff_data_t end; /* 192 4 */ /* XXX 4 bytes hole, try to pack */ to __u32 mark; /* 172 4 */ __u16 vlan_tci; /* 176 2 */ /* XXX 2 bytes hole, try to pack */ sk_buff_data_t transport_header; /* 180 4 */ sk_buff_data_t network_header; /* 184 4 */ Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2008-07-14tipc: Optimization to multicast name lookup algorithmAllan Stephens
This patch simplifies and speeds up TIPC's algorithm for identifying on-node and off-node destinations that overlap a multicast name sequence range. Rather than traversing the list of all known name publications within the cluster, it now traverses the (potentially much shorter) list of name publications made by the node itself, and determines if any off-node destinations exist by comparing the sizes of the two lists. (Since the node list must be a subset of the cluster list, a difference in sizes means that at least one off-node destination must exist.)

2008-07-14tipc: Add missing locks when inspecting node list & link listAllan Stephens

2008-07-14tipc: Fix bug in scope checking for multicast messagesAllan Stephens
This patch ensures that TIPC's multicast message name lookup algorithm does individualized scope checking for each published name it examines. Previously, scope checking was only done for the first name in a name table publication list, which could result in incoming multicast messages being delivered to ports publishing names with "node" scope, or not being delivered to ports publishing names with "cluster" or "zone" scope.

2008-07-14tipc: Eliminate improper use of TIPC_OK error codeAllan Stephens
This patch corrects many places where TIPC routines indicated successful completion by returning TIPC_OK instead of 0. (The TIPC_OK symbol has the value 0, but it should only be used in contexts that deal with the error code field of a TIPC message header.)

2008-07-14tipc: Fix race condition that could cause accept() to failAllan Stephens
This patch ensurs that accept() returns successfully even when the newly created socket is immediately disconnected by its peer. Previously, accept() would fail if it was unable to pass back the optional address info for the socket's peer before the socket became disconnected; TIPC now allows accept() to gather peer address information after disconnection. As a bonus, the revised code accesses the socket's port more efficiently, without the overhead incurred by a reference table lookup.

2008-07-14tipc: Remove unneeded parameter to tipc_createport_raw()Allan Stephens
