      Btrfs: make sure the backref walker catches all refs to our extent · ed8c4913
      Josef Bacik 提交于
      Because we don't mess with the offset into the extent for compressed we will
      properly find both extents for this case
      
      [extent a][extent b][rest of extent a]
      
      but because we already added a ref for the front half we won't add the inode
      information for the second half.  This causes us to leak that memory and not
      print out the other offset when we do logical-resolve.  So fix this by calling
      ulist_add_merge and then add our eie to the existing entry if there is one.
      With this patch we get both offsets out of logical-resolve.  With this and the
      other 2 patches I've sent we now pass btrfs/276 on my vm with compress-force=lzo
      set.  Thanks,

      Btrfs: fix backref walking when we hit a compressed extent · 8ca15e05
      Josef Bacik 提交于
      If you do btrfs inspect-internal logical-resolve on a compressed extent that has
      been partly overwritten it won't find anything.  This is because we try and
      match the extent offset we've searched for based on the extent offset in the
      data extent entry.  However this doesn't work for compressed extents because the
      offsets are for the uncompressed size, not the compressed size.  So instead only
      do this check if we are not compressed, that way we can get an actual entry for
      the physical offset rather than nothing for compressed.  Thanks,

      Btrfs: do not offset physical if we're compressed · b76bb701
      Josef Bacik 提交于
      xfstest btrfs/276 was freaking out on slower boxes partly because fiemap was
      offsetting the physical based on the extent offset.  This is perfectly fine with
      uncompressed extents, however the extent offset is into the uncompressed area,
      not the compressed.  So we can return a physical value that isn't at all within
      the area we have allocated on disk.  Fix this by returning the start of the
      extent if it is compressed no matter what the offset.  Thanks,

      Btrfs: fix a bug of snapshot-aware defrag to make it work on partial extents · e68afa49
      Liu Bo 提交于
      For partial extents, snapshot-aware defrag does not work as expected,
      since
      a) we use the wrong logical offset to search for parents, which should be
         disk_bytenr + extent_offset, not just disk_bytenr,
      b) 'offset' returned by the backref walking just refers to key.offset, not
         the 'offset' stored in btrfs_extent_data_ref which is
         (key.offset - extent_offset).
      
      The reproducer:
      $ mkfs.btrfs sda
      $ mount sda /mnt
      $ btrfs sub create /mnt/sub
      $ for i in `seq 5 -1 1`; do dd if=/dev/zero of=/mnt/sub/foo bs=5k count=1 seek=$i conv=notrunc oflag=sync; done
      $ btrfs sub snap /mnt/sub /mnt/snap1
      $ btrfs sub snap /mnt/sub /mnt/snap2
      $ sync; btrfs filesystem defrag /mnt/sub/foo;
      $ umount /mnt
      $ btrfs-debug-tree sda (Here we can check whether the defrag operation is snapshot-awared.

      netlabel: use domain based selectors when address based selectors are not available · 6a8b7f0c
      Paul Moore 提交于
      NetLabel has the ability to selectively assign network security labels
      to outbound traffic based on either the LSM's "domain" (different for
      each LSM), the network destination, or a combination of both.  Depending
      on the type of traffic, local or forwarded, and the type of traffic
      selector, domain or address based, different hooks are used to label the
      traffic; the goal being minimal overhead.
      
      Unfortunately, there is a bug such that a system using NetLabel domain
      based traffic selectors does not correctly label outbound local traffic
      that is not assigned to a socket.  The issue is that in these cases
      the associated NetLabel hook only looks at the address based selectors
      and not the domain based selectors.  This patch corrects this by
      checking both the domain and address based selectors so that the correct
      labeling is applied, regardless of the configuration type.
      
      In order to acomplish this fix, this patch also simplifies some of the
      NetLabel domainhash structures to use a more common outbound traffic
      mapping type: struct netlbl_dommap_def.  This simplifies some of the code
      in this patch and paves the way for further simplifications in the
      future.

      net: check net.core.somaxconn sysctl values · 5f671d6b
      Roman Gushchin 提交于
      It's possible to assign an invalid value to the net.core.somaxconn
      sysctl variable, because there is no checks at all.
      
      The sk_max_ack_backlog field of the sock structure is defined as
      unsigned short. Therefore, the backlog argument in inet_listen()
      shouldn't exceed USHRT_MAX. The backlog argument in the listen() syscall
      is truncated to the somaxconn value. So, the somaxconn value shouldn't
      exceed 65535 (USHRT_MAX).
      Also, negative values of somaxconn are meaningless.
      
      before:
      $ sysctl -w net.core.somaxconn=256
      net.core.somaxconn = 256
      $ sysctl -w net.core.somaxconn=65536
      net.core.somaxconn = 65536
      $ sysctl -w net.core.somaxconn=-100
      net.core.somaxconn = -100
      
      after:
      $ sysctl -w net.core.somaxconn=256
      net.core.somaxconn = 256
      $ sysctl -w net.core.somaxconn=65536
      error: "Invalid argument" setting key "net.core.somaxconn"
      $ sysctl -w net.core.somaxconn=-100

      Commit 5c766d64 ("ipv4: introduce address lifetime") leaves the ifa
      resource that was allocated via inet_alloc_ifa() unfreed when returning
      the function with -EINVAL. Thus, free it first via inet_free_ifa().

      r8169: remove "PHY reset until link up" log spam · 9bb8eeb5
      Lekensteyn 提交于
      This message was added in commit a7154cb8 (June 2004, [PATCH] r8169:
      link handling and phy reset rework) and is printed every ten seconds
      when no cable is connected and runtime power management is disabled.
      (Before that commit, "Reset RTL8169s PHY" would be printed instead.)

      htb: fix sign extension bug · cbd37556
      stephen hemminger 提交于
      When userspace passes a large priority value
      the assignment of the unsigned value hopt->prio
      to  signed int cl->prio causes cl->prio to become negative and the
      comparison is with TC_HTB_NUMPRIO is always false.
      
      The result is that HTB crashes by referencing outside
      the array when processing packets. With this patch the large value
      wraps around like other values outside the normal range.

      Pull powerpc fixes from Ben Herrenschmidt:
       "Here is not quite a handful of powerpc fixes for rc3.
      
        The windfarm fix is a regression fix (though not a new one), the PMU
        interrupt rename is not a fix per-se but has been submitted a long
        time ago and I kept forgetting to put it in (it puts us back in sync
        with x86), the other perf bit is just about putting an API/ABI bit
        definition in the right place for userspace to consume, and finally,
        we have a fix for the VPHN (Virtual Partition Home Node) feature
        (notification that the hypervisor is moving nodes around) which could
        cause lockups so we may as well fix it now"
      
      * 'merge' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc:
        powerpc/windfarm: Fix noisy slots-fan on Xserve (rm31)

      Pull ARM fixes from Russell King:
       "I've thought long and hard about what to say for this pull request,
        and I really can't work out anything sane to say to summarise much of
        these commits.  The problem is, for most of these are, yet again, lots
        of small bits scattered around the place without any real overall
        theme to them"
      
      Most notable is probably the kuser page helper improvements.
