      qlge: Fix firmware mailbox command timeout. · da039451
      Ron Mercer authored
      The mailbox command process would only process a maximum of 5 unrelated
      firmware events while waiting for it's command completion status.
      It should process an unlimited number of events while waiting for a maximum of 5 seconds.

      AF_RAW: Augment raw_send_hdrinc to expand skb to fit iphdr->ihl (v2) · 55888dfb

      Augment raw_send_hdrinc to correct for incorrect ip header length values
      
      A series of oopses was reported to me recently.  Apparently when using AF_RAW
      sockets to send data to peers that were reachable via ipsec encapsulation,
      people could panic or BUG halt their systems.
      
      I've tracked the problem down to user space sending an invalid ip header over an
      AF_RAW socket with IP_HDRINCL set to 1.
      
      Basically what happens is that userspace sends down an ip frame that includes
      only the header (no data), but sets the ip header ihl value to a large number,
      one that is larger than the total amount of data passed to the sendmsg call.  In
      raw_send_hdrincl, we allocate an skb based on the size of the data in the msghdr
      that was passed in, but assume the data is all valid.  Later during ipsec
      encapsulation, xfrm4_tranport_output moves the entire frame back in the skbuff
      to provide headroom for the ipsec headers.  During this operation, the
      skb->transport_header is repointed to a spot computed by
      skb->network_header + the ip header length (ihl).  Since so little data was
      passed in relative to the value of ihl provided by the raw socket, we point
      transport header to an unknown location, resulting in various crashes.
      
      This fix for this is pretty straightforward, simply validate the value of of
      iph->ihl when sending over a raw socket.  If (iph->ihl*4U) > user data buffer
      size, drop the frame and return -EINVAL.  I just confirmed this fixes the
      reported crashes.

      bonding: fix a race condition in calls to slave MII ioctls · d9d52832
      Jiri Bohac authored
      In mii monitor mode, bond_check_dev_link() calls the the ioctl
      handler of slave devices. It stores the ndo_do_ioctl function
      pointer to a static (!) ioctl variable and later uses it to call the
      handler with the IOCTL macro.
      
      If another thread executes bond_check_dev_link() at the same time
      (even with a different bond, which none of the locks prevent), a
      race condition occurs. If the two racing slaves have different
      drivers, this may result in one driver's ioctl handler being
      called with a pointer to a net_device controlled with a different
      driver, resulting in unpredictable breakage.
      
      Unless I am overlooking something, the "static" must be a
      copy'n'paste error (?).

      mac80211: fix for incorrect sequence number on hostapd injected frames · 9b1ce526
      Björn Smedman authored
      When hostapd injects a frame, e.g. an authentication or association
      response, mac80211 looks for a suitable access point virtual interface
      to associate the frame with based on its source address. This makes it
      possible e.g. to correctly assign sequence numbers to the frames.
      
      A small typo in the ethernet address comparison statement caused a
      failure to find a suitable ap interface. Sequence numbers on such
      frames where therefore left unassigned causing some clients
      (especially windows-based 11b/g clients) to reject them and fail to
      authenticate or associate with the access point. This patch fixes the
      typo in the address comparison statement.

      mac80211: fix ibss joining · d419b9f0
      Reinette Chatre authored
      Recent commit "mac80211: fix logic error ibss merge bssid check" fixed
      joining of ibss cell when static bssid is provided. In this case
      ifibss->bssid is set before the cell is joined and comparing that address
      to a bss should thus always succeed. Unfortunately this change broke the
      other case of joining a ibss cell without providing a static bssid where
      the value of ifibss->bssid is not set before the cell is joined.
      
      Since ifibss->bssid may be set before or after joining the cell we do not
      learn anything by comparing it to a known bss. Remove this check.

      "b43: Fix PPC crash in rfkill polling on unload" fixed the bug reported
      in Bugzilla No. 14181; however, it introduced a new bug. Whenever the
      radio switch was turned off, it was necessary to unload and reload
      the driver for it to recognize the switch again.
      
      This patch fixes both the original bug in #14181 and the bug introduced by
      the previous patch. It must be stated, however, that if there is a BCM4306/3
      with an rfkill switch (not yet proven), then the driver will need an
      unload/reload cycle to turn the device back on.
