      airo_cs: Remove typedef local_info_t · 61ecba64
      Himangi Saraogi authored
      The Linux kernel coding style guidelines suggest not using typedefs
      for structure types. This patch gets rid of the typedef for
      local_info_t. Also, the name of the struct is changed to drop the _t,
      to make the name look less typedef-like.
      
      The following Coccinelle semantic patch detects the case:

      net: Always untag vlan-tagged traffic on input. · 0d5501c1
      Vlad Yasevich authored
      Currently the functionality to untag traffic on input resides
      as part of the vlan module and is build only when VLAN support
      is enabled in the kernel.  When VLAN is disabled, the function
      vlan_untag() turns into a stub and doesn't really untag the
      packets.  This seems to create an interesting interaction
      between VMs supporting checksum offloading and some network drivers.
      
      There are some drivers that do not allow the user to change
      tx-vlan-offload feature of the driver.  These drivers also seem
      to assume that any VLAN-tagged traffic they transmit will
      have the vlan information in the vlan_tci and not in the vlan
      header already in the skb.  When transmitting skbs that already
      have tagged data with partial checksum set, the checksum doesn't
      appear to be updated correctly by the card thus resulting in a
      failure to establish TCP connections.
      
      The following is a packet trace taken on the receiver where a
      sender is a VM with a VLAN configued.  The host VM is running on
      doest not have VLAN support and the outging interface on the
      host is tg3:
      10:12:43.503055 52:54:00:ae:42:3f > 28:d2:44:7d:c2:de, ethertype 802.1Q
      (0x8100), length 78: vlan 100, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 27243,
      offset 0, flags [DF], proto TCP (6), length 60)
          10.0.100.1.58545 > 10.0.100.10.ircu-2: Flags [S], cksum 0xdc39 (incorrect
      -> 0x48d9), seq 1069378582, win 29200, options [mss 1460,sackOK,TS val
      4294837885 ecr 0,nop,wscale 7], length 0
      10:12:44.505556 52:54:00:ae:42:3f > 28:d2:44:7d:c2:de, ethertype 802.1Q
      (0x8100), length 78: vlan 100, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 27244,
      offset 0, flags [DF], proto TCP (6), length 60)
          10.0.100.1.58545 > 10.0.100.10.ircu-2: Flags [S], cksum 0xdc39 (incorrect
      -> 0x44ee), seq 1069378582, win 29200, options [mss 1460,sackOK,TS val
      4294838888 ecr 0,nop,wscale 7], length 0
      
      This connection finally times out.
      
      I've only access to the TG3 hardware in this configuration thus have
      only tested this with TG3 driver.  There are a lot of other drivers
      that do not permit user changes to vlan acceleration features, and
      I don't know if they all suffere from a similar issue.
      
      The patch attempt to fix this another way.  It moves the vlan header
      stipping code out of the vlan module and always builds it into the
      kernel network core.  This way, even if vlan is not supported on
      a virtualizatoin host, the virtual machines running on top of such
      host will still work with VLANs enabled.

      ====================
      Netfilter fixes for net
      
      The following patchset contains fixes for your net tree, they are:
      
      1) Unitialize the set element key and data from the commit path,
         otherwise this leaks chain refcount if the transaction is aborted,
         reported by Thomas Graf.
      
      2) Fix crash when updating chains without no counters in nf_tables,
         this slipped through in the new transaction infrastructure, reported
         by Matteo Croce.
      
      3) Replace all mutex_lock_interruptible() by mutex_lock() in the Netfilter
         tree, suggested by Patrick McHardy. This implicitly fixes the problem
         that Eric Dumazet reported in: http://patchwork.ozlabs.org/patch/373076/
      
      4) Fix error return code in nf_tables when deleting set element in
         nf_tables if the transaction cannot be allocated, from Julia Lawall.
