      net: irda: using kzalloc() instead of kmalloc() to avoid strncpy() issue. · ff0102ee
      Chen Gang 提交于
      'discovery->data.info' length is 22, NICKNAME_MAX_LEN is 21, so the
      strncpy() will always left the last byte of 'discovery->data.info'
      uninitialized.
      
      When 'text' length is longer than 21 (NICKNAME_MAX_LEN), if still left
      the last byte of 'discovery->data.info' uninitialized, the next
      strlen() will cause issue.
      
      Also 'discovery->data' is 'struct irda_device_info' which defined in
      "include/uapi/...", it may copy to user mode, so need whole initialized.
      
      All together, need use kzalloc() instead of kmalloc() to initialize all
      members firstly.

      netlabel: improve domain mapping validation · 6b21e1b7
      Paul Moore 提交于
      The net/netlabel/netlabel_domainhash.c:netlbl_domhsh_add() function
      does not properly validate new domain hash entries resulting in
      potential problems when an administrator attempts to add an invalid
      entry.  One such problem, as reported by Vlad Halilov, is a kernel
      BUG (found in netlabel_domainhash.c:netlbl_domhsh_audit_add()) when
      adding an IPv6 outbound mapping with a CIPSO configuration.
      
      This patch corrects this problem by adding the necessary validation
      code to netlbl_domhsh_add() via the newly created
      netlbl_domhsh_validate() function.
      
      Ideally this patch should also be pushed to the currently active
      -stable trees.

      batman-adv: Fix rcu_barrier() miss due to double call_rcu() in TT code · 72822225
      Linus Lüssing 提交于
      rcu_barrier() only waits for the currently scheduled rcu functions
      to finish - it won't wait for any function scheduled via another
      call_rcu() within an rcu scheduled function.
      
      Unfortunately our batadv_tt_orig_list_entry_free_ref() does just that,
      via a batadv_orig_node_free_ref() call, leading to our rcu_barrier()
      call potentially missing such a batadv_orig_node_free_ref().
      
      This patch fixes this issue by calling the batadv_orig_node_free_rcu()
      directly from the rcu callback, removing the unnecessary, additional
      call_rcu() layer here.

      bonding: allow TSO being set on bonding master · b0ce3508
      Eric Dumazet 提交于
      In some situations, we need to disable TSO on bonding slaves.
      
      bonding device automatically unset TSO in bond_fix_features(), and
      performance is not good because :
      
      1) We consume more cpu cycles.
      
      2) GSO segmentation has some bugs leading to out of order TCP packets
      if this segmentation is done before virtual device. This particular
      problem will be addressed in a separate patch.
      
      This patch allows TSO being set/unset on the bonding master,
      so that GSO segmentation is done after bonding layer.

      in a context outside of softirq context, and thus is susceptible to
      deadlock should an interrupt occur.
      
      Use __netif_tx_lock_bh()/__netif_tx_unlock_bh() instead.

      tcp: gso: do not generate out of order packets · 6ff50cd5
      Eric Dumazet 提交于
      GSO TCP handler has following issues :
      
      1) ooo_okay from original GSO packet is duplicated to all segments
      2) segments (but the last one) are orphaned, so transmit path can not
      get transmit queue number from the socket. This happens if GSO
      segmentation is done before stacked device for example.
      
      Result is we can send packets from a given TCP flow to different TX
      queues (if using multiqueue NICS). This generates OOO problems and
      spurious SACK & retransmits.
      
      Fix this by keeping socket pointer set for all segments.
      
      This means that every segment must also have a destructor, and the
      original gso skb truesize must be split on all segments, to keep
      precise sk->sk_wmem_alloc accounting.

      ====================
      The following patchset contains three Netfilter fixes and update
      for the MAINTAINER file for your net tree, they are:
      
      * Fix crash if nf_log_packet is called from conntrack, in that case
        both interfaces are NULL, from Hans Schillstrom. This bug introduced
        with the logging netns support in the previous merge window.
      
      * Fix compilation of nf_log and nf_queue without CONFIG_PROC_FS,
        from myself. This bug was introduced in the previous merge window
        with the new netns support for the netfilter logging infrastructure.
      
      * Fix possible crash in xt_TCPOPTSTRIP due to missing sanity
        checkings to validate that the TCP header is well-formed, from
        myself. I can find this bug in 2.6.25, probably it's been there
        since the beginning. I'll pass this to -stable.
      
      * Update MAINTAINER file to point to new nf trees at git.kernel.org,
        remove Harald and use M: instead of P: (now obsolete tag) to
        keep Jozsef in the list of people.

      Fabio Estevam 提交于
      commit 54309fa6 ("net: fec: fix kernel oops when plug/unplug cable many times")
      introduced the following 'if' block in the beginning of fec_start():
      
      	if (netif_running(ndev)) {
      		netif_device_detach(ndev);
      		napi_disable(&fep->napi);

      		netif_tx_lock_bh(ndev);
      	}
      
      Then later in the end of fec_restart() there is another block that calls the
      opposite of each one of these functions.
      
      The correct approach would be to also call them with in the reverse order, so
      that we have as result:
      
      	if (netif_running(ndev)) {
      		netif_tx_unlock_bh(ndev);
      		netif_wake_queue(ndev);

      ipg: fix an unsigned widening cast of '~' truncation issue · 0d709d91
      Dan Carpenter 提交于
      The bug here is this code from ipg_nic_hard_start_xmit():
      
      	txfd->tfc &= cpu_to_le64(~IPG_TFC_TFDDONE);
      
      IPG_TFC_TFDDONE is 0x0000000080000000 so it's an unsigned int.  The
      negated value is 0x7fffffff but 0xffffffff7fffffff was intended.
      
      The other values in this file don't need to be changed but I did it for
      consistency.

      qlge: fix dma map leak when the last chunk is not allocated · ef380794
      Thadeu Lima de Souza Cascardo 提交于
      qlge allocates chunks from a page that it maps and unmaps that page when
      the last chunk is released. When the driver is unloaded or the card is
      removed, all chunks are released and the page is unmapped for the last
      chunk.
      
      However, when the last chunk of a page is not allocated and the device
      is removed, that page is not unmapped. In fact, its last reference is
      not put and there's also a page leak. This bug prevents a device from
      being properly hotplugged.
      
      When the DMA API debug option is enabled, the following messages show
      the pending DMA allocation after we remove the driver.
      
      This patch fixes the bug by unmapping and putting the page from the ring
      if its last chunk has not been allocated.
      
      pci 0005:98:00.0: DMA-API: device driver has pending DMA allocations while released from device [count=1]
      One of leaked entries details: [device address=0x0000000060a80000] [size=65536 bytes] [mapped with DMA_FROM_DEVICE] [mapped as page]
