      SELinux: Fix possible NULL pointer dereference in selinux_inode_permission() · 3dc91d43

      While running stress tests on adding and deleting ftrace instances I hit
      this bug:

      Investigating, I found that the inode->i_security was NULL, and the
      dereference of it caused the oops.
      
      in selinux_inode_permission():
      
      	isec = inode->i_security;
      
      	rc = avc_has_perm_noaudit(sid, isec->sid, isec->sclass, perms, 0, &avd);
      
      Note, the crash came from stressing the deletion and reading of debugfs
      files.  I was not able to recreate this via normal files.  But I'm not
      sure they are safe.  It may just be that the race window is much harder
      to hit.
      
      What seems to have happened (and what I have traced), is the file is
      being opened at the same time the file or directory is being deleted.
      As the dentry and inode locks are not held during the path walk, nor is
      the inodes ref counts being incremented, there is nothing saving these
      structures from being discarded except for an rcu_read_lock().
      
      The rcu_read_lock() protects against freeing of the inode, but it does
      not protect freeing of the inode_security_struct.  Now if the freeing of
      the i_security happens with a call_rcu(), and the i_security field of
      the inode is not changed (it gets freed as the inode gets freed) then
      there will be no issue here.  (Linus Torvalds suggested not setting the
      field to NULL such that we do not need to check if it is NULL in the
      permission check).
      
      Note, this is a hack, but it fixes the problem at hand.  A real fix is
      to restructure the destroy_inode() to call all the destructor handlers
      from the RCU callback.  But that is a major job to do, and requires a
      lot of work.  For now, we just band-aid this bug with this fix (it
      works), and work on a more maintainable solution in the future.

      since shrink_huge_zero_page() can free the huge_zero_page, and we have
      no hold of our own on it here (except where the fourth test holds
      page_table_lock and has checked pmd_same), it's possible for it to
      answer yes the first time, but no to the second or third test.  Change
      all those last three to tests for NULL page.
      
      (Note: this is not the same issue as trinity's DEBUG_PAGEALLOC BUG
      in copy_page_rep with RSI: ffff88009c422000, reported by Sasha Levin
      in https://lkml.org/lkml/2013/3/29/103.  I believe that one is due
      to the source page being split, and a tail page freed, while copy
      is in progress; and not a problem without DEBUG_PAGEALLOC, since
      the pmd_same check will prevent a miscopy from being made visible.)

      block: null_blk: fix queue leak inside removing device · 518d00b7
      Ming Lei authored
      
      
      When queue_mode is NULL_Q_MQ and null_blk is being removed,
      blk_cleanup_queue() isn't called to cleanup queue, so the queue
      allocated won't be freed.
      
      This patch calls blk_cleanup_queue() for MQ to drain all pending
      requests first and release the reference counter of queue kobject, then
      blk_mq_free_queue() will be called in queue kobject's release handler
      when queue kobject's reference counter drops to zero.

      It can be a problem when a pattern is loaded via the firmware interface.
      LP55xx common driver has already locked the mutex in 'lp55xx_firmware_loaded()'.
      So it should be deleted.
      
      On the other hand, locks are required in store_engine_load()
      on updating program memory.

      net: core: explicitly select a txq before doing l2 forwarding · f663dd9a
      Jason Wang authored
      
      
      Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The
      will cause several issues:
      
      - NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan
        instead of lower device which misses the necessary txq synchronization for
        lower device such as txq stopping or frozen required by dev watchdog or
        control path.
      - dev_hard_start_xmit() was called with NULL txq which bypasses the net device
        watchdog.
      - dev_hard_start_xmit() does not check txq everywhere which will lead a crash
        when tso is disabled for lower device.
      
      Fix this by explicitly introducing a new param for .ndo_select_queue() for just
      selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also
      extended to accept this parameter and dev_queue_xmit_accel() was used to do l2
      forwarding transmission.
      
      With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need
      to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep
      a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of
      dev_queue_xmit() to do the transmission.
      
      In the future, it was also required for macvtap l2 forwarding support since it
      provides a necessary synchronization method.

      macvlan: forbid L2 fowarding offload for macvtap · b13ba1b8
      Jason Wang authored
      
      
      L2 fowarding offload will bypass the rx handler of real device. This will make
      the packet could not be forwarded to macvtap device. Another problem is the
      dev_hard_start_xmit() called for macvtap does not have any synchronization.
      
      Fix this by forbidding L2 forwarding for macvtap.

      bnx2x: fix DMA unmapping of TSO split BDs · 95e92fd4
      Michal Schmidt authored
      
      
      bnx2x triggers warnings with CONFIG_DMA_API_DEBUG=y:
      
        WARNING: CPU: 0 PID: 2253 at lib/dma-debug.c:887 check_unmap+0xf8/0x920()
        bnx2x 0000:28:00.0: DMA-API: device driver frees DMA memory with

        [unmap size=66 bytes]
      
      The reason is that bnx2x splits a TSO BD into two BDs (headers + data)
      using one DMA mapping for both, but it uses only the length of the first
      BD when unmapping.
      
      This patch fixes the bug by unmapping the whole length of the two BDs.

      ipv6: add link-local, sit and loopback address with INFINITY_LIFE_TIME · 07edd741
      Hannes Frederic Sowa authored
      In the past the IFA_PERMANENT flag indicated, that the valid and preferred
      lifetime where ignored. Since change fad8da3e
      
       ("ipv6 addrconf: fix
      preferred lifetime state-changing behavior while valid_lft is infinity")
      we honour at least the preferred lifetime on those addresses. As such
      the valid lifetime gets recalculated and updated to 0.
      
      If loopback address is added manually this problem does not occur.
      Also if NetworkManager manages IPv6, those addresses will get added via
      inet6_rtm_newaddr and thus will have a correct lifetime, too.

      bnx2x: prevent WARN during driver unload · 9a2620c8
      Yuval Mintz authored
      Starting with commit 80c33ddd
      
       "net: add might_sleep() call to napi_disable"
      bnx2x fails the might_sleep tests causing a stack trace to appear whenever
      the driver is unloaded, as local_bh_disable() is being called before
      napi_disable().
      
      This changes the locking schematics related to CONFIG_NET_RX_BUSY_POLL,
      preventing the need for calling local_bh_disable() and thus eliminating
      the issue.

      ====================
      The following patchset contains two patches:
      
      * fix the IRC NAT helper which was broken when adding (incomplete) IPv6
        support, from Daniel Borkmann.
      
      * Refine the previous bugtrap that Jesper added to catch problems for the
        usage of the sequence adjustment extension in IPVs in Dec 16th, it may
        spam messages in case of finding a real bug.

      tipc: correctly unlink packets from deferred packet queue · 732256b9
      Erik Hugne authored
      When we pull a received packet from a link's 'deferred packets' queue
      for processing, its 'next' pointer is not cleared, and still refers to
      the next packet in that queue, if any. This is incorrect, but caused
      no harm before commit 40ba3cdf ("tipc:
      message reassembly using fragment chain") was introduced. After that
      commit, it may sometimes lead to the following oops:

      This happens when the last fragment of a message has passed through the
      the receiving link's 'deferred packets' queue, and at least one other
      packet was added to that queue while it was there. After the fragment
      chain with the complete message has been successfully delivered to the
      receiving socket, it is released. Since 'next' pointer of the last
      fragment in the released chain now is non-NULL, we get the crash shown
      above.
      
      We fix this by clearing the 'next' pointer of all received packets,
      including those being pulled from the 'deferred' queue, before they
      undergo any further processing.
      
      Fixes: 40ba3cdf

      Jani for co-maintainer!
      
      Jani has been a really active bug-scrubber in the past few months.
      I've asked him whether he wants to do this in a more official capacity
      and he agreed. I've already chatted with Dave and Jesse and they
      support this.
      
      Note that everyone can't now just relax because "Jani will do all the
      bug scrubbing" - au contraire expect more nagging and poking now that
      we have more bandwidth.
      
      Longer-term the plan is to share more of the maintainer duties, but we
      need to fix up the infrastructure a bit first (like moving the git
      repo to a common location).
      
      While at it also add the newly set-up patchwork instance.
