      GFS2: make sure rgrps are up to date in func gfs2_blk2rgrpd · 58884c4d
      Bob Peterson 提交于
      This patch adds a call to gfs2_rindex_update from function gfs2_blk2rgrpd
      and removes calls to it that are made redundant by it. The problem is
      that a gfs2_grow can add rgrps to the rindex, then put those rgrps into
      use, thus rendering the rindex we read in at mount time incomplete.

      GFS2: Eliminate sd_rindex_mutex · 6aad1c3d
      Bob Peterson 提交于
      Over time, we've slowly eliminated the use of sd_rindex_mutex.
      Up to this point, it was only used in two places: function
      gfs2_ri_total (which totals the file system size by reading
      and parsing the rindex file) and function gfs2_rindex_update
      which updates the rgrps in memory. Both of these functions have
      the rindex glock to protect them, so the rindex is unnecessary.
      Since gfs2_grow writes to the rindex via the meta_fs, the mutex
      is in the wrong order according to the normal rules. This patch
      eliminates the mutex entirely to avoid the problem.

      For example, if you have ten processes, all doing:

      GFS2: FITRIM ioctl support · 66fc061b
      Steven Whitehouse 提交于
      The FITRIM ioctl provides an alternative way to send discard requests to
      the underlying device. Using the discard mount option results in every
      freed block generating a discard request to the block device. This can
      be slow, since many block devices can only process discard requests of
      larger sizes, and also such operations can be time consuming.
      
      Rather than using the discard mount option, FITRIM allows a sweep of the
      filesystem on an occasional basis, and also to optionally avoid sending
      down discard requests for smaller regions.
      
      In GFS2 FITRIM will work at resource group granularity. There is a flag
      for each resource group which keeps track of which resource groups have
      been trimmed. This flag is reset whenever a deallocation occurs in the
      resource group, and set whenever a successful FITRIM of that resource
      group has taken place. This helps to reduce repeated discard requests
      for the same block ranges, again improving performance.

      GFS2: glock statistics gathering · a245769f
      Steven Whitehouse 提交于
      The stats are divided into two sets: those relating to the
      super block and those relating to an individual glock. The
      super block stats are done on a per cpu basis in order to
      try and reduce the overhead of gathering them. They are also
      further divided by glock type.
      
      In the case of both the super block and glock statistics,
      the same information is gathered in each case. The super
      block statistics are used to provide default values for
      most of the glock statistics, so that newly created glocks
      should have, as far as possible, a sensible starting point.
      
      The statistics are divided into three pairs of mean and
      variance, plus two counters. The mean/variance pairs are
      smoothed exponential estimates and the algorithm used is
      one which will be very familiar to those used to calculation
      of round trip times in network code.
      
      The three pairs of mean/variance measure the following
      things:
      
       1. DLM lock time (non-blocking requests)
       2. DLM lock time (blocking requests)
       3. Inter-request time (again to the DLM)
      
      A non-blocking request is one which will complete right
      away, whatever the state of the DLM lock in question. That
      currently means any requests when (a) the current state of
      the lock is exclusive (b) the requested state is either null
      or unlocked or (c) the "try lock" flag is set. A blocking
      request covers all the other lock requests.
      
      There are two counters. The first is there primarily to show
      how many lock requests have been made, and thus how much data
      has gone into the mean/variance calculations. The other counter
      is counting queueing of holders at the top layer of the glock
      code. Hopefully that number will be a lot larger than the number
      of dlm lock requests issued.
      
      So why gather these statistics? There are several reasons
      we'd like to get a better idea of these timings:
      
      1. To be able to better set the glock "min hold time"
      2. To spot performance issues more easily
      3. To improve the algorithm for selecting resource groups for
      allocation (to base it on lock wait time, rather than blindly
      using a "try lock")
      Due to the smoothing action of the updates, a step change in
      some input quantity being sampled will only fully be taken
      into account after 8 samples (or 4 for the variance) and this
      needs to be carefully considered when interpreting the
      results.
      
      Knowing both the time it takes a lock request to complete and
      the average time between lock requests for a glock means we
      can compute the total percentage of the time for which the
      node is able to use a glock vs. time that the rest of the
      cluster has its share. That will be very useful when setting
      the lock min hold time.
      
      The other point to remember is that all times are in
      nanoseconds. Great care has been taken to ensure that we
      measure exactly the quantities that we want, as accurately
      as possible. There are always inaccuracies in any
      measuring system, but I hope this is as accurate as we
      can reasonably make it.

      IOMMU fixes for Linux 3.3-rc5
      
      All the fixes are for the OMAP IOMMU driver. The first patch is the
      biggest one. It fixes the calls of the function omap_find_iovm_area() in
      the omap-iommu-debug module which expects a 'struct device' parameter
      since commit fabdbca8 instead of an omap_iommu handle. The
      omap-iommu-debug code still passed the handle to the function which
      caused a crash.
      
      The second patch fixes a NULL pointer dereference in the OMAP code and
      the third patch makes sure that the omap-iommu is initialized before the
      omap-isp driver, which relies on the iommu. The last patch is only a
      workaround until defered probing is implemented.

      25) When we added VF (virtual function) attributes for network device
         dumps, this potentially bloats up the size of the dump of one
         network device such that the dump size is too large for the buffer
         allocated by properly written netlink applications.
      
         In particular, if you add 255 VFs to a network device, parts of
         GLIBC stop working.
      
         To fix this, we add an attribute that is used to turn on these
         extended portions of the network device dump.  Sophisticaed
         applications like 'ip' that want to see this stuff  will be changed
         to set the attribute, whereas things like GLIBC that don't care
         about VFs simply will not, and therefore won't be busted by the
         mere presence of VFs on a network device.
      
         Thanks to the tireless work of Greg Rose on this fix.

      we have #ifdef's in code, but this is the low-hanging fruit.

      autofs: work around unhappy compat problem on x86-64 · a32744d4
      Ian Kent 提交于
      When the autofs protocol version 5 packet type was added in commit
      5c0a32fc ("autofs4: add new packet type for v5 communications"), it
      obvously tried quite hard to be word-size agnostic, and uses explicitly
      sized fields that are all correctly aligned.
      
      However, with the final "char name[NAME_MAX+1]" array at the end, the
      actual size of the structure ends up being not very well defined:
      because the struct isn't marked 'packed', doing a "sizeof()" on it will
      align the size of the struct up to the biggest alignment of the members
      it has.
      
      And despite all the members being the same, the alignment of them is
      different: a "__u64" has 4-byte alignment on x86-32, but native 8-byte
      alignment on x86-64.  And while 'NAME_MAX+1' ends up being a nice round
      number (256), the name[] array starts out a 4-byte aligned.
      
      End result: the "packed" size of the structure is 300 bytes: 4-byte, but
      not 8-byte aligned.
      
      As a result, despite all the fields being in the same place on all
      architectures, sizeof() will round up that size to 304 bytes on
      architectures that have 8-byte alignment for u64.
      
      Note that this is *not* a problem for 32-bit compat mode on POWER, since
      there __u64 is 8-byte aligned even in 32-bit mode.  But on x86, 32-bit
      and 64-bit alignment is different for 64-bit entities, and as a result
      the structure that has exactly the same layout has different sizes.
      
      So on x86-64, but no other architecture, we will just subtract 4 from
      the size of the structure when running in a compat task.  That way we
      will write the properly sized packet that user mode expects.
      
      Not pretty.  Sadly, this very subtle, and unnecessary, size difference
      has been encoded in user space that wants to read packets of *exactly*
      the right size, and will refuse to touch anything else.

      sfc: Fix assignment of ip_summed for pre-allocated skbs · ff3bc1e7
      Ben Hutchings 提交于
      When pre-allocating skbs for received packets, we set ip_summed =
      CHECKSUM_UNNCESSARY.  We used to change it back to CHECKSUM_NONE when
      the received packet had an incorrect checksum or unhandled protocol.
      
      Commit bc8acf2c ('drivers/net: avoid
      some skb->ip_summed initializations') mistakenly replaced the latter
      assignment with a DEBUG-only assertion that ip_summed ==
      CHECKSUM_NONE.  This assertion is always false, but it seems no-one
      has exercised this code path in a DEBUG build.
      
      Fix this by moving our assignment of CHECKSUM_UNNECESSARY into
      efx_rx_packet_gro().

      ppp: fix 'ppp_mp_reconstruct bad seq' errors · 8a49ad6e
      Ben McKeegan 提交于
      This patch fixes a (mostly cosmetic) bug introduced by the patch
      'ppp: Use SKB queue abstraction interfaces in fragment processing'
      found here: http://www.spinics.net/lists/netdev/msg153312.html
      
      The above patch rewrote and moved the code responsible for cleaning
      up discarded fragments but the new code does not catch every case
      where this is necessary.  This results in some discarded fragments
      remaining in the queue, and triggering a 'bad seq' error on the
      subsequent call to ppp_mp_reconstruct.  Fragments are discarded
      whenever other fragments of the same frame have been lost.
      This can generate a lot of unwanted and misleading log messages.
      
      This patch also adds additional detail to the debug logging to
      make it clearer which fragments were lost and which other fragments
      were discarded as a result of losses. (Run pppd with 'kdebug 1'
      option to enable debug logging.)
