      netfilter: nf_conntrack: fix racy timer handling with reliable events · 5b423f6a
      Pablo Neira Ayuso 提交于
      Existing code assumes that del_timer returns true for alive conntrack
      entries. However, this is not true if reliable events are enabled.
      In that case, del_timer may return true for entries that were
      just inserted in the dying list. Note that packets / ctnetlink may
      hold references to conntrack entries that were just inserted to such
      list.
      
      This patch fixes the issue by adding an independent timer for
      event delivery. This increases the size of the ecache extension.
      Still we can revisit this later and use variable size extensions
      to allocate this area on demand.

      net: ipv4: ipmr_expire_timer causes crash when removing net namespace · acbb219d
      Francesco Ruggeri 提交于
      When tearing down a net namespace, ipv4 mr_table structures are freed
      without first deactivating their timers. This can result in a crash in
      run_timer_softirq.
      This patch mimics the corresponding behaviour in ipv6.
      Locking and synchronization seem to be adequate.
      We are about to kfree mrt, so existing code should already make sure that
      no other references to mrt are pending or can be created by incoming traffic.
      The functions invoked here do not cause new references to mrt or other
      race conditions to be created.
      Invoking del_timer_sync guarantees that ipmr_expire_timer is inactive.
      Both ipmr_expire_process (whose completion we may have to wait in
      del_timer_sync) and mroute_clean_tables internally use mfc_unres_lock
      or other synchronizations when needed, and they both only modify mrt.

      e1000e: DoS while TSO enabled caused by link partner with small MSS · d821a4c4
      Bruce Allan 提交于
      With a low enough MSS on the link partner and TSO enabled locally, the
      networking stack can periodically send a very large (e.g.  64KB) TCP
      message for which the driver will attempt to use more Tx descriptors than
      are available by default in the Tx ring.  This is due to a workaround in
      the code that imposes a limit of only 4 MSS-sized segments per descriptor
      which appears to be a carry-over from the older e1000 driver and may be
      applicable only to some older PCI or PCIx parts which are not supported in
      e1000e.  When the driver gets a message that is too large to fit across the
      configured number of Tx descriptors, it stops the upper stack from queueing
      any more and gets stuck in this state.  After a timeout, the upper stack
      assumes the adapter is hung and calls the driver to reset it.
      
      Remove the unnecessary limitation of using up to only 4 MSS-sized segments
      per Tx descriptor, and put in a hard failure test to catch when attempting
      to check for message sizes larger than would fit in the whole Tx ring.
      Refactor the remaining logic that limits the size of data per Tx descriptor
      from a seemingly arbitrary 8KB to a limit based on the dynamic size of the
      Tx packet buffer as described in the hardware specification.
      
      Also, fix the logic in the check for space in the Tx ring for the next
      largest possible packet after the current one has been successfully queued
      for transmit, and use the appropriate defines for default ring sizes in
      e1000_probe instead of magic values.
      
      This issue goes back to the introduction of e1000e in 2.6.24 when it was
      split off from e1000.
