      perf tools: Support callchain sorting based on addresses · 99571ab3
      由 Andi Kleen 提交于 
      With programs with very large functions it can be useful to distinguish
the callgraph nodes on more than just function names. So for example if
you have multiple calls to the same function, it ends up being separate
nodes in the chain.

This patch adds a new key field to the callgraph options, that allows
comparing nodes on functions (as today, default) and addresses.

Longer term it would be nice to also handle src lines, but that would
need more changes and address is a reasonable proxy for it today.

I right now reference the global params, as there was no simple way to
register a params pointer.

      perf bench: Fix memcpy benchmark for large sizes · a198996c
      由 Andi Kleen 提交于 
      The glibc calloc() function has an optimization to not explicitely
memset() very large calloc allocations that just came from mmap(),
because they are known to be zero.

This could result in the perf memcpy benchmark reading only from
the zero page, which gives unrealistic results.

Always call memset explicitly on the source area to avoid this problem.

   7) Add missing locking on vxlan device removal, from Stephen

   8) xen-netfront has to make two passes over an SKB to prepare it for
      transfer.  One pass calculates the number of slots needed, the
      second massages the SKB and fills the slots.  Unfortunately, the
      first pass doesn't calculate the number of slots properly so we
      can end up trying to build a MAX_SKB_FRAGS + 1 SKB which doesn't
      work out so well.  Fix from Jan Beulich with help and discussion
      with several others.

   9) Fix a similar problem in tun and macvtap, which have to split up
      scatter-gather elements at PAGE_SIZE boundaries.  Don't do
      zerocopy if it would result in a > MAX_SKB_FRAGS skb.  Fixes from

      由 Eric Dumazet 提交于 
      In commit 48cc32d3
("vlan: don't deliver frames for unknown vlans to protocols")
Florian made sure we set pkt_type to PACKET_OTHERHOST
if the vlan id is set and we could find a vlan device for this
particular id.

But we also have a problem if prio bits are set.

Steinar reported an issue on a router receiving IPv6 frames with a
vlan tag of 4000 (id 0, prio 2), and tunneled into a sit device,
because skb->vlan_tci is set.

Forwarded frame is completely corrupted : We can see (8100:4000)
being inserted in the middle of IPv6 source address :

16:48:00.780413 IP6 2001:16d8:8100:4000:ee1c:0:9d9:bc87 >

It seems we are not really ready to properly cope with this right now.

We can probably do better in future kernels :
vlan_get_ingress_priority() should be a netdev property instead of
a per vlan_dev one.

For stable kernels, lets clear vlan_tci to fix the bugs.

      We try to linearize part of the skb when the number of iov is greater than
MAX_SKB_FRAGS. This is not enough since each single vector may occupy more than
one pages, so zerocopy_sg_fromiovec() may still fail and may break the guest
network.

Solve this problem by calculate the pages needed for iov before trying to do
zerocopy and switch to use copy instead of zerocopy if it needs more than
MAX_SKB_FRAGS.

This is done through introducing a new helper to count the pages for iov, and
call uarg->callback() manually when switching from zerocopy to copy to notify
vhost.

We can do further optimization on top.

      pkt_sched: sch_qfq: remove a source of high packet delay/jitter · 87f40dd6
      由 Paolo Valente 提交于 
      QFQ+ inherits from QFQ a design choice that may cause a high packet
delay/jitter and a severe short-term unfairness. As QFQ, QFQ+ uses a
special quantity, the system virtual time, to track the service
provided by the ideal system it approximates. When a packet is
dequeued, this quantity must be incremented by the size of the packet,
divided by the sum of the weights of the aggregates waiting to be
served. Tracking this sum correctly is a non-trivial task, because, to
preserve tight service guarantees, the decrement of this sum must be
delayed in a special way [1]: this sum can be decremented only after
that its value would decrease also in the ideal system approximated by
QFQ+. For efficiency, QFQ+ keeps track only of the 'instantaneous'
weight sum, increased and decreased immediately as the weight of an
aggregate changes, and as an aggregate is created or destroyed (which,
in its turn, happens as a consequence of some class being
created/destroyed/changed). However, to avoid the problems caused to
service guarantees by these immediate decreases, QFQ+ increments the
system virtual time using the maximum value allowed for the weight
sum, 2^10, in place of the dynamic, instantaneous value. The
instantaneous value of the weight sum is used only to check whether a
request of weight increase or a class creation can be satisfied.

Unfortunately, the problems caused by this choice are worse than the
temporary degradation of the service guarantees that may occur, when a
class is changed or destroyed, if the instantaneous value of the
weight sum was used to update the system virtual time. In fact, the
fraction of the link bandwidth guaranteed by QFQ+ to each aggregate is
equal to the ratio between the weight of the aggregate and the sum of
the weights of the competing aggregates. The packet delay guaranteed
to the aggregate is instead inversely proportional to the guaranteed
bandwidth. By using the maximum possible value, and not the actual
value of the weight sum, QFQ+ provides each aggregate with the worst
possible service guarantees, and not with service guarantees related
to the actual set of competing aggregates. To see the consequences of
this fact, consider the following simple example.

Suppose that only the following aggregates are backlogged, i.e., that
only the classes in the following aggregates have packets to transmit:
one aggregate with weight 10, say A, and ten aggregates with weight 1,
say B1, B2, ..., B10. In particular, suppose that these aggregates are
always backlogged. Given the weight distribution, the smoothest and
fairest service order would be:
A B1 A B2 A B3 A B4 A B5 A B6 A B7 A B8 A B9 A B10 A B1 A B2 ...

QFQ+ would provide exactly this optimal service if it used the actual
value for the weight sum instead of the maximum possible value, i.e.,
11 instead of 2^10. In contrast, since QFQ+ uses the latter value, it
serves aggregates as follows (easy to prove and to reproduce
experimentally):
A B1 B2 B3 B4 B5 B6 B7 B8 B9 B10 A A A A A A A A A A B1 B2 ... B10 A A ...

By replacing 10 with N in the above example, and by increasing N, one
can increase at will the maximum packet delay and the jitter
experienced by the classes in aggregate A.

This patch addresses this issue by just using the above
'instantaneous' value of the weight sum, instead of the maximum
possible value, when updating the system virtual time.  After the
instantaneous weight sum is decreased, QFQ+ may deviate from the ideal
service for a time interval in the order of the time to serve one
maximum-size packet for each backlogged class. The worst-case extent
of the deviation exhibited by QFQ+ during this time interval [1] is
basically the same as of the deviation described above (but, without
this patch, QFQ+ suffers from such a deviation all the time). Finally,
this patch modifies the comment to the function qfq_slot_insert, to
make it coherent with the fact that the weight sum used by QFQ+ can
now be lower than the maximum possible value.

 "Here are some driver core patches for 3.11-rc2.  They aren't really

  Also here is the ability to create binary files as attribute groups,
  to solve that race condition, which was impossible to do before this,

  different subtrees, instead of having to live in my driver-core tree,
  causing merge nightmares in linux-next for the next few months.

  These were finalized too late for the -rc1 merge window, which is why
  they were didn't make that pull request, testing and review from
  others didn't happen until a few weeks ago, and then there's the whole
  distraction of the past few days, which prevented these from getting
  to you sooner, sorry about that.

  Oh, and there's a bugfix for the documentation build warning in here
  as well.  All of these have been in linux-next this week, with no
  reported problems"

      Merge branch 'cpuinit_phase2' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux · 3f334c20
      由 Linus Torvalds 提交于 
      Pull phase two of __cpuinit removal from Paul Gortmaker:
 "With the __cpuinit infrastructure removed earlier, this group of
  commits only removes the function/data tagging that was done with the
  various (now no-op) __cpuinit related prefixes.

  Now that the dust has settled with yesterday's v3.11-rc1, there
  hopefully shouldn't be any new users leaking back in tree, but I think
  we can leave the harmless no-op stubs there for a release as a
  courtesy to those who still have out of tree stuff and weren't paying
  attention.

  Although the commits are against the recent tag to allow for minor
  context refreshes for things like yesterday's v3.11-rc1~ slab content,
  the patches have been largely unchanged for weeks, aside from such
  trivial updates.

  For detail junkies, the largely boring and mostly irrelevant history
  of the patches can be viewed at:

    http://git.kernel.org/cgit/linux/kernel/git/paulg/cpuinit-delete.git

  If nothing else, I guess it does at least demonstrate the level of
  involvement required to shepherd such a treewide change to completion.

  This is the same repository of patches that has been applied to the
  end of the daily linux-next branches for the past several weeks"
