      vlan: Don't store VLAN tag in cb · 6aa895b0
      Patrick McHardy authored
      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 */

      tipc: Optimization to multicast name lookup algorithm · 968edbe1
      Allan Stephens authored
      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.)

      tipc: Fix bug in scope checking for multicast messages · 08d2cf0f
      Allan Stephens authored
      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.

      This patch corrects many places where TIPC routines indicated
      successful completion by returning TIPC_OK instead of 0.

      tipc: Fix race condition that could cause accept() to fail · 2da59918
      Allan Stephens authored
      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.

      tipc: Remove unneeded parameter to tipc_createport_raw() · 0ea52241
      Allan Stephens authored
      This patch eliminates an unneeded parameter when creating a low-level
      TIPC port object.  Instead of returning both the pointer to the port
      structure and the port's reference ID, it now returns only the pointer
      since the port structure contains the reference ID as one of its fields.

      netlabel: return msg overflow error from netlbl_cipsov4_list faster · 83aa2e96
      Denis V. Lunev authored
      Currently, we are trying to place the information from the kernel to
      1, 2, 3 and 4 pages sequentially. These pages are allocated via slab.
      Though, from the slab point of view steps 3 and 4 are equivalent on
      most architectures. So, lets skip 3 pages attempt.
      
      By the way, should we switch from .doit to .dumpit interface here?
      The amount of data seems quite big for me.

      tun: Fix/rewrite packet filtering logic · f271b2cc
      Max Krasnyansky authored
      Please see the following thread to get some context on this
      	http://marc.info/?l=linux-netdev&m=121564433018903&w=2
      
      Basically the issue is that current multi-cast filtering stuff in
      the TUN/TAP driver is seriously broken.
      Original patch went in without proper review and ACK. It was broken and
      confusing to start with and subsequent patches broke it completely.
      To give you an idea of what's broken here are some of the issues:
      
      - Very confusing comments throughout the code that imply that the
      character device is a network interface in its own right, and that packets
      are passed between the two nics. Which is completely wrong.
      
      - Wrong set of ioctls is used for setting up filters. They look like
      shortcuts for manipulating state of the tun/tap network interface but
      in reality manipulate the state of the TX filter.
      
      - ioctls that were originally used for setting address of the the TX filter
      got "fixed" and now set the address of the network interface itself. Which
      made filter totaly useless.
      
      - Filtering is done too late. Instead of filtering early on, to avoid
      unnecessary wakeups, filtering is done in the read() call.
      
      The list goes on and on :)
      
      So the patch cleans all that up. It introduces simple and clean interface for
      setting up TX filters (TUNSETTXFILTER + tun_filter spec) and does filtering
      before enqueuing the packets.
      
      TX filtering is useful in the scenarios where TAP is part of a bridge, in
      which case it gets all broadcast, multicast and potentially other packets when
      the bridge is learning. So for example Ethernet tunnelling app may want to
      setup TX filters to avoid tunnelling multicast traffic. QEMU and other
      hypervisors can push RX filtering that is currently done in the guest into the
      host context therefore saving wakeups and unnecessary data transfer.

      ipv4: Fix ipmr unregister device oops · 7dc00c82
      Wang Chen authored
      An oops happens during device unregister.
      
      The following oops happened when I add two tunnels, which
      use a same device, and then delete one tunnel.
      Obviously deleting tunnel "A" causes device unregister, which
      send a notification, and after receiving notification, ipmr do
      unregister again for tunnel "B" which also use same device.
      That is wrong.
      After receiving notification, ipmr only needs to decrease reference
      count and don't do duplicated unregister.
      Fortunately, IPv6 side doesn't add tunnel in ip6mr, so it's clean.
      
      This patch fixs:
      - unregister device oops
      - using after dev_put()
      
      Here is the oops:

      dev_set_promiscuity/allmulti return error number if overflow happened.
      
      Here, we check the positive increment for allmulti to get error return.
      
      PS: For unwinding tunnel creating, we let ipip->ioctl() to handle it.

      dev_set_promiscuity/allmulti might overflow.
      Commit: "netdevice: Fix promiscuity and allmulti overflow" in net-next makes
      dev_set_promiscuity/allmulti return error number if overflow happened.
      
      In bond_alb and bond_main, we check all positive increment for promiscuity
      and allmulti to get error return.
      But there are still two problems left.
      1. Some code path has no mechanism to signal errors upstream.
      2. If there are multi slaves, it's hard to tell which slaves increment
         promisc/allmulti successfully and which failed.
      So I left these problems to be FIXME.
      Fortunately, the overflow is very rare case.
