kvm/irqchip: Speed up KVM_SET_GSI_ROUTING
When starting lots of dataplane devices the bootup takes very long on Christian's s390 with irqfd patches. With larger setups he is even able to trigger some timeouts in some components. Turns out that the KVM_SET_GSI_ROUTING ioctl takes very long (strace claims up to 0.1 sec) when having multiple CPUs. This is caused by the synchronize_rcu and the HZ=100 of s390. By changing the code to use a private srcu we can speed things up. This patch reduces the boot time till mounting root from 8 to 2 seconds on my s390 guest with 100 disks. Uses of hlist_for_each_entry_rcu, hlist_add_head_rcu, hlist_del_init_rcu are fine because they do not have lockdep checks (hlist_for_each_entry_rcu uses rcu_dereference_raw rather than rcu_dereference, and write-sides do not do rcu lockdep at all). Note that we're hardly relying on the "sleepable" part of srcu. We just want SRCU's faster detection of grace periods. Testing was done by Andrew Theurer using netperf tests STREAM, MAERTS and RR. The difference between results "before" and "after" the patch has mean -0.2% and standard deviation 0.6%. Using a paired t-test on the data points says that there is a 2.5% probability that the patch is the cause of the performance difference (rather than a random fluctuation). (Restricting the t-test to RR, which is the most likely to be affected, changes the numbers to respectively -0.3% mean, 0.7% stdev, and 8% probability that the numbers actually say something about the patch. The probability increases mostly because there are fewer data points). Cc: Marcelo Tosatti <mtosatti@redhat.com> Cc: Michael S.

KVM: add kvm_is_error_gpa() helper
It's quite common (in the s390 guest access code) to test if a guest physical address points to a valid guest memory area or not.

KVM: VMX: speed up wildcard MMIO EVENTFD
With KVM, MMIO is much slower than PIO, due to the need to
do page walk and emulation. But with EPT, it does not have to be: we
know the address from the VMCS so if the address is unique, we can look
up the eventfd directly, bypassing emulation.
Unfortunately, this only works if userspace does not need to match on
access length and data. The implementation adds a separate FAST_MMIO
bus internally. This serves two purposes:
- minimize overhead for old userspace that does not use eventfd with lengtth = 0
- minimize disruption in other code (since we don't know the length,
devices on the MMIO bus only get a valid address in write, this
way we don't need to touch all devices to teach them to handle
an invalid length)
At the moment, this optimization only has effect for EPT on x86.
It will be possible to speed up MMIO for NPT and MMU using the same
idea in the future.
With this patch applied, on VMX MMIO EVENTFD is essentially as fast as PIO.
I was unable to detect any measureable slowdown to non-eventfd MMIO.
Making MMIO faster is important for the upcoming virtio 1.0 which
includes an MMIO signalling capability.
The idea was suggested by Peter Anvin. Lots of thanks to Gleb for
pre-review and suggestions.

KVM: support any-length wildcard ioeventfd
It is sometimes benefitial to ignore IO size, and only match on address. In hindsight this would have been a better default than matching length when KVM_IOEVENTFD_FLAG_DATAMATCH is not set, In particular, this kind of access can be optimized on VMX: there no need to do page lookups. This can currently be done with many ioeventfds but in a suboptimal way. However we can't change kernel/userspace ABI without risk of breaking some applications. Use len = 0 to mean "ignore length for matching" in a more optimal way. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> |

7) We have several cases of using socket based communications to
implement a tunnel. For example, some tunnels are encapsulations
over UDP so we use an internal kernel UDP socket to do the
transmits.
These tunnels should behave just like other software devices and
pass the packets on down to the next layer.
Most importantly we want the top-level socket (eg TCP) that created
the traffic to be charged for the SKB memory.
However, once you get into the IP output path, we have code that
assumed that whatever was attached to skb->sk is an IP socket.
To keep the top-level socket being charged for the SKB memory,
whilst satisfying the needs of the IP output path, we now pass in an
explicit 'sk' argument.
From Eric Dumazet.
8) ping_init_sock() leaks group info, from Xiaoming Wang.

ipv4: add a sock pointer to dst->output() path.
In the dst->output() path for ipv4, the code assumes the skb it has to
transmit is attached to an inet socket, specifically via
ip_mc_output() : The sk_mc_loop() test triggers a WARN_ON() when the
provider of the packet is an AF_PACKET socket.
The dst->output() method gets an additional 'struct sock *sk'
parameter. This needs a cascade of changes so that this parameter can
be propagated from vxlan to final consumer.

netfilter: nf_tables: fix nft_cmp_fast failure on big endian for size < 4
nft_cmp_fast is used for equality comparisions of size <= 4. For comparisions of size < 4 byte a mask is calculated that is applied to both the data from userspace (during initialization) and the register value (during runtime). Both values are stored using (in effect) memcpy to a memory area that is then interpreted as u32 by nft_cmp_fast. This works fine on little endian since smaller types have the same base address, however on big endian this is not true and the smaller types are interpreted as a big number with trailing zero bytes. The mask therefore must not include the lower bytes, but the higher bytes on big endian. Add a helper function that does a cpu_to_le32 to switch the bytes on big endian. Since we're dealing with a mask of just consequitive bits, this works out fine. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> |

The highlights this round include:
- iser-target support for T10 PI (DIF) offloads (Sagi + Or)
- Fix Task Aborted Status (TAS) handling in target-core (Alex Leung)
- Pass in transport supported PI at session initialization (Sagi + MKP + nab)
- Add WRITE_INSERT + READ_STRIP T10 PI support in target-core (nab + Sagi)
- Fix iscsi-target ERL=2 ASYNC_EVENT connection pointer bug (nab)
- Fix tcm_fc use-after-free of ft_tpg (Andy Grover)
- Use correct ib_sg_dma primitives in ib_isert (Mike Marciniszyn)
Also, note the virtio-scsi + vhost-scsi changes to expose T10 PI
metadata into KVM guest have been left-out for now, as there where a
few comments from MST + Paolo that where not able to be addressed in
time for v3.15. Please expect this feature for v3.16-rc1"

This includes the final patch to clean up and fix the issue with the
design of tracepoints and how a user could register a tracepoint and have that tracepoint not be activated but no error was shown. The design was for an out of tree module but broke in tree users. The clean up was to remove the saving of the hash table of tracepoint names such that they can be enabled before they exist (enabling a module tracepoint before that module is loaded). This added more complexity than needed. The clean up was to remove that code and just enable tracepoints that exist or fail if they do not. This removed a lot of code as well as the complexity that it brought. As a side effect, instead of registering a tracepoint by its name, the tracepoint needs to be registered with the tracepoint descriptor. This removes having to duplicate the tracepoint names that are enabled. The second patch was added that simplified the way modules were searched for. This cleanup required changes that were in the 3.15 queue as well as some changes that were added late in the 3.14-rc cycle. This final change waited till the two were merged in upstream and then the change was added and full tests were run. Unfortunately, the test found some errors, but after it was already submitted to the for-next branch and not to be rebased. Sparse errors were detected by Fengguang Wu's bot tests, and my internal tests discovered that the anonymous union initialization triggered a bug in older gcc compilers. Luckily, there was a bugzilla for the gcc bug which gave a work around to the problem. The third and fourth patch handled the sparse error and the gcc bug respectively.

net: Fix use after free by removing length arg from sk_data_ready callbacks.
Several spots in the kernel perform a sequence like: skb_queue_tail(&sk->s_receive_queue, skb); sk->sk_data_ready(sk, skb->len); But at the moment we place the SKB onto the socket receive queue it can be consumed and freed up. So this skb->len access is potentially to freed up memory. Furthermore, the skb->len can be modified by the consumer so it is possible that the value isn't accurate. And finally, no actual implementation of this callback actually uses the length argument. And since nobody actually cared about it's value, lots of call sites pass arbitrary values in such as '0' and even '1'. So just remove the length argument from the callback, that way there is no confusion whatsoever and all of these use-after-free cases get fixed as a side effect. Based upon a patch by Eric Dumazet and his suggestion to audit this issue tree-wide. Signed-off-by: David S. Miller <davem@davemloft.net> |

mm: slab/slub: use page->list consistently instead of page->lru
'struct page' has two list_head fields: 'lru' and 'list'. Conveniently, they are unioned together. This means that code can use them interchangably, which gets horribly confusing like with this nugget from slab.c: > list_del(&page->lru); > if (page->active == cachep->num) > list_add(&page->list, &n->slabs_full); This patch makes the slab and slub code use page->lru universally instead of mixing ->list and ->lru. So, the new rule is: page->lru is what the you use if you want to keep your page on a list. Don't like the fact that it's not called ->list? Too bad.

AUDIT: make audit_is_compat depend on CONFIG_AUDIT_COMPAT_GENERIC
On systems with CONFIG_COMPAT we introduced the new requirement that audit_classify_compat_syscall() exists. This wasn't true for everything (apparently not for "tilegx", which I know less that nothing about.) Instead of wrapping the preprocessor optomization with CONFIG_COMPAT we should have used the new CONFIG_AUDIT_COMPAT_GENERIC. This patch uses that config option to make sure only arches which intend to implement this have the requirement. This works fine for tilegx according to Chris Metcalf Signed-off-by: Eric Paris <eparis@redhat.com> |

NVMe: Retry failed commands with non-fatal errors
For commands returned with failed status, queue these for resubmission and continue retrying them until success or for a limited amount of time. The final timeout was arbitrarily chosen so requests can't be retried indefinitely. Since these are requeued on the nvmeq that submitted the command, the callbacks have to take an nvmeq instead of an nvme_dev as a parameter so that we can use the locked queue to append the iod to retry later. The nvme_iod conviently can be used to track how long we've been trying to successfully complete an iod request. The nvme_iod also provides the nvme prp dma mappings, so I had to move a few things around so we can keep those mappings.

NVMe: per-cpu io queues
The device's IO queues are associated with CPUs, so we can use a per-cpu variable to map the a qid to a cpu. This provides a convienient way to optimally assign queues to multiple cpus when the device supports fewer queues than the host has cpus. The previous implementation may have assigned these poorly in these situations. This patch addresses this by sharing queues among cpus that are "close" together and should have a lower lock contention penalty.

Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block layer fixes from Jens Axboe:
"A small collection of fixes that should go in before -rc1. The pull
request contains:
- A two patch fix for a regression with block enabled tagging caused
by a commit in the initial pull request. One patch is from Martin
and ensures that SCSI doesn't truncate 64-bit block flags, the
other one is from me and prevents us from double using struct
request queuelist for both completion and busy tags. This caused
anything from a boot crash for some, to crashes under load.
- A blk-mq fix for a potential soft stall when hot unplugging CPUs
with busy IO.
- percpu_counter fix is listed in here, that caused a suspend issue
with virtio-blk due to percpu counters having an inconsistent state
during CPU removal. Andrew sent this in separately a few days ago,
but it's here. JFYI.
- A few fixes for block integrity from Martin.
- A ratelimit fix for loop from Mike Galbraith, to avoid spewing too
much in error cases"

Pull i2c updates from Wolfram Sang:
"Here is the pull request from the i2c subsystem. It got a little
delayed because I needed to wait for a dependency to be included
(commit b424080a9e08: "reset: Add optional resets and stubs"). Plus,
I had some email problems. All done now, the highlights are:
- drivers can now deprecate their use of i2c classes. That shouldn't
be used on embedded platforms anyhow and was often blindly
copy&pasted. This mechanism gives users time to switch away and
ultimately boot faster once the use of classes for those drivers is
gone for good.
- new drivers for QUP, Cadence, efm32
- tracepoint support for I2C and SMBus
- bigger cleanups for the mv64xxx, nomadik, and designware drivers
And the usual bugfixes, cleanups, feature additions. Most stuff has
been in linux-next for a while. Just some hot fixes and new drivers
were added a bit more recently."
