Add the ability to collect I/O statistics on user-defined regions of a
device-mapper device. This dm-stats code required the reintroduction of a div64_u64_rem() helper, but as a separate method that doesn't slow down div64_u64() -- especially on 32-bit systems. Allow the error target to replace request-based DM devices (e.g. multipath) in addition to bio-based DM devices. Various other small code fixes and improvements to thin-provisioning, DM cache and the DM ioctl interface. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.13 (GNU/Linux) iQEcBAABAgAGBQJSLyNnAAoJEMUj8QotnQNaXVEIAKA1l43enaGiROBZEZXgAGUY 1JUsnHES4ujyn/jtT39jPTQf9AW/rS4FUCrZiXG2aaNHXo7+7cdVoBHAiWc7mXad budBSqn47W7WDyFlQarKwsuYFcdLnqdnieRDMXQ1cN5dl4Rx61LclnsylQd4SSS0 lznXkfOTquetDSuEPOuUHJDZufdacw3PpxWbTKGJld40fd7YZfGWQoG0ek1OeqqL fA30DTlYnkFyhheLCjFcDY6H55Rt7QpBWOUAa2XXLR6GLfk5iFK99autjWk2xTPT nppRwQrw9VH+HdW0jGLU+LRs1Y3nxwT9OBLWt9wav87Smdg/7jQAjwde9eKbO2k= =3ooH -----END PGP SIGNATURE----- Merge tag 'dm-3.12-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device-mapper updates from Mike Snitzer: "Add the ability to collect I/O statistics on user-defined regions of a device-mapper device.

VFIO updates include safer default file flags for VFIO device fds,
an external user interface exported to allow other modules to hold references to VFIO groups, a fix to test for extended config space on PCIe and PCI-x, and new hot reset interfaces for PCI devices which allows the user to do PCI bus/slot resets when all of the devices affected by the reset are owned by the user. For this last feature, the PCI bus reset interface, I depend on changes already merged from Bjorn's PCI pull request. I therefore merged my tree up to commit |

dm: add statistics support
Support the collection of I/O statistics on user-defined regions of a DM device. If no regions are defined no statistics are collected so there isn't any performance impact. Only bio-based DM devices are currently supported. Each user-defined region specifies a starting sector, length and step. Individual statistics will be collected for each step-sized area within the range specified. The I/O statistics counters for each step-sized area of a region are in the same format as /sys/block/*/stat or /proc/diskstats but extra counters (12 and 13) are provided: total time spent reading and writing in milliseconds. All these counters may be accessed by sending the @stats_print message to the appropriate DM device via dmsetup. The creation of DM statistics will allocate memory via kmalloc or fallback to using vmalloc space. At most, 1/4 of the overall system memory may be allocated by DM statistics. The admin can see how much memory is used by reading /sys/module/dm_mod/parameters/stats_current_allocated_bytes See Documentation/device-mapper/statistics.txt for more details.

"Noteworthy changes this time around:
1) Multicast rejoin support for team driver, from Jiri Pirko.
2) Centralize and simplify TCP RTT measurement handling in order to
reduce the impact of bad RTO seeding from SYN/ACKs. Also, when
both timestamps and local RTT measurements are available prefer
the later because there are broken middleware devices which
scramble the timestamp.
From Yuchung Cheng.

memory consumed to queue up unsend user data. From Eric Dumazet.
4) Add a "physical port ID" abstraction for network devices, from
Jiri Pirko.
5) Add a "suppress" operation to influence fib_rules lookups, from

11) Add new SYNPROXY netfilter target, from Patrick McHardy.
12) Compute a rate approximation for sending in TCP sockets, and use

a new packet scheduler which takes advantage of this estimate when
available. From Eric Dumazet.
13) Allow AF_PACKET fanouts with random selection, from Daniel

Conflicts: drivers/net/ethernet/stmicro/stmmac/stmmac_platform.c net/bridge/br_multicast.c net/ipv6/sit.c The conflicts were minor: 1) sit.c changes overlap with change to ip_tunnel_xmit() signature. 2) br_multicast.c had an overlap between computing max_delay using msecs_to_jiffies and turning MLDV2_MRC() into an inline function with a name using lowercase instead of uppercase letters. 3) stmmac had two overlapping changes, one which conditionally allocated and hooked up a dma_cfg based upon the presence of the pbl OF property, and another one handling store-and-forward DMA made.

"This is the main drm pull request, I have some overlap with sound and
arm-soc, the sound patch is acked and may conflict based on -next
reports but should be a trivial fixup, which I'll leave to you!
Highlights:
- new drivers:
MSM driver from Rob Clark
- non-drm:
switcheroo and hdmi audio driver support for secondary GPU
poweroff, so drivers can use runtime PM to poweroff the GPUs. This
can save 5 or 6W on some optimus laptops.
- drm core:
combined GEM and TTM VMA manager
per-filp mmap permission tracking
initial rendernode support (via a runtime enable for now, until we get api stable),
remove old proc support,
lots of cleanups of legacy code
hdmi vendor infoframes and 4k modes
lots of gem/prime locking and races fixes
async pageflip scaffolding
drm bridge objects
- i915:
Haswell PC8+ support and eLLC support, HDMI 4K support, initial
per-process VMA pieces, watermark reworks, convert to generic hdmi
infoframes, encoder reworking, fastboot support,
- radeon:
CIK PM support, remove 3d blit code in favour of DMA engines,
Berlin GPU support, HDMI audio fixes
- nouveau:
secondary GPU power down support for optimus laptops, lots of
fixes, use MSI, VP3 engine support
- exynos:
runtime pm support for g2d, DT support, remove non-DT,
- tda998x i2c driver:
lots of fixes for sync issues
- gma500:
lots of cleanups
- rcar:
add LVDS support, fbdev emulation,
- tegra:
just minor fixes"

New features for 3.12:
* Added aggressive extent caching using the extent status tree. This
can actually decrease memory usage in read-mostly workloads since
the information is much more compactly stored in the extent status
tree than if we had to keep the extent tree metadata blocks in the
buffer cache. This also improves Asynchronous I/O since it is it
makes much less likely that we need to do metadata I/O to lookup the
extent tree information.
* Improve the recovery after corrupted allocation bitmaps are found
when running in errors=ignore mode.
Also fixed some writeback vs. truncate races when using a blocksize
less than the page size.

vfio-pci: PCI hot reset interface
The current VFIO_DEVICE_RESET interface only maps to PCI use cases where we can isolate the reset to the individual PCI function. This means the device must support FLR (PCIe or AF), PM reset on D3hot->D0 transition, device specific reset, or be a singleton device on a bus for a secondary bus reset. FLR does not have widespread support, PM reset is not very reliable, and bus topology is dictated by the system and device design. We need to provide a means for a user to induce a bus reset in cases where the existing mechanisms are not available or not reliable. This device specific extension to VFIO provides the user with this ability. Two new ioctls are introduced: - VFIO_DEVICE_PCI_GET_HOT_RESET_INFO - VFIO_DEVICE_PCI_HOT_RESET The first provides the user with information about the extent of devices affected by a hot reset. This is essentially a list of devices and the IOMMU groups they belong to. The user may then initiate a hot reset by calling the second ioctl. We must be careful that the user has ownership of all the affected devices found via the first ioctl, so the second ioctl takes a list of file descriptors for the VFIO groups affected by the reset. Each group must have IOMMU protection established for the ioctl to succeed. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> |

net: sync some IP headers with glibc
Solution:
=========
- Synchronize linux's `include/uapi/linux/in6.h'
with glibc's `inet/netinet/in.h'.
- Synchronize glibc's `inet/netinet/in.h with linux's
`include/uapi/linux/in6.h'.
- Allow including the headers in either other.
- First header included defines the structures and macros.
Details:
========
The kernel promises not to break the UAPI ABI so I don't
see why we can't just have the two userspace headers
coordinate?
If you include the kernel headers first you get those,
and if you include the glibc headers first you get those,
and the following patch arranges a coordination and
synchronization between the two.
Let's handle `include/uapi/linux/in6.h' from linux,
and `inet/netinet/in.h' from glibc and ensure they compile
in any order and preserve the required ABI.
These two patches pass the following compile tests:
cat >> test1.c <<EOF
int main (void) {
return 0;
}
EOF
gcc -c test1.c
cat >> test2.c <<EOF
int main (void) {
return 0;
}
EOF
gcc -c test2.c
One wrinkle is that the kernel has a different name for one of
the members in ipv6_mreq. In the kernel patch we create a macro
to cover the uses of the old name, and while that's not entirely
clean it's one of the best solutions (aside from an anonymous
union which has other issues).
I've reviewed the code and it looks to me like the ABI is
assured and everything matches on both sides.
Notes:
- You want netinet/in.h to include bits/in.h as early as possible,
but it needs in_addr so define in_addr early.
- You want bits/in.h included as early as possible so you can use
the linux specific code to define __USE_KERNEL_DEFS based on
the _UAPI_* macro definition and use those to cull in.h.
- glibc was missing IPPROTO_MH, added here.
Compile tested and inspected.

Merge branches 'perf-urgent-for-linus' and 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf changes from Ingo Molnar:
"As a first remark I'd like to point out that the obsolete '-f'
(--force) option, which has not done anything for several releases,
has been removed from 'perf record' and related utilities. Everyone
please update muscle memory accordingly! :-)
Main changes on the perf kernel side:
- Performance optimizations:
. for trace events, by Steve Rostedt.
. for time values, by Peter Zijlstra
- New hardware support:
. for Intel Silvermont (22nm Atom) CPUs, by Zheng Yan
. for Intel SNB-EP uncore PMUs, by Zheng Yan
- Enhanced hardware support:
. for Intel uncore PMUs: add filter support for QPI boxes, by Zheng Yan
- Core perf events code enhancements and fixes:
. for full-nohz feature handling, by Frederic Weisbecker
. for group events, by Jiri Olsa
. for call chains, by Frederic Weisbecker
. for event stream parsing, by Adrian Hunter
- New ABI details:
. Add attr->mmap2 attribute, by Stephane Eranian
. Add PERF_EVENT_IOC_ID ioctl to return event ID, by Jiri Olsa
. Export u64 time_zero on the mmap header page to allow TSC
calculation, by Adrian Hunter
. Add dummy software event, by Adrian Hunter.
. Add a new PERF_SAMPLE_IDENTIFIER to make samples always
parseable, by Adrian Hunter.
. Make Power7 events available via sysfs, by Runzhen Wang.
- Code cleanups and refactorings:
. for nohz-full, by Frederic Weisbecker
. for group events, by Jiri Olsa
- Documentation updates:
. for perf_event_type, by Peter Zijlstra
Main changes on the perf tooling side (some of these tooling changes
utilize the above kernel side changes):
- Lots of 'perf trace' enhancements:
. Make 'perf trace' command line arguments consistent with
'perf record', by David Ahern.
. Allow specifying syscalls a la strace, by Arnaldo Carvalho de Melo.
. Add --verbose and -o/--output options, by Arnaldo Carvalho de Melo.
. Support ! in -e expressions, to filter a list of syscalls,
by Arnaldo Carvalho de Melo.
. Arg formatting improvements to allow masking arguments in
syscalls such as futex and open, where the some arguments are
ignored and thus should not be printed depending on other args,
by Arnaldo Carvalho de Melo.
. Beautify futex open, openat, open_by_handle_at, lseek and futex
syscalls, by Arnaldo Carvalho de Melo.
. Add option to analyze events in a file versus live, so that
one can do:
[root@zoo ~]# perf record -a -e raw_syscalls:* sleep 1
[ perf record: Woken up 0 times to write data ]
[ perf record: Captured and wrote 25.150 MB perf.data (~1098836 samples) ]

Input: introduce BTN/ABS bits for drums and guitars
There are a bunch of guitar and drums devices out there that all report
similar data. To avoid reporting this as BTN_MISC or ABS_MISC, we
allocate some proper namespace for them. Note that most of these devices
are toys and we cannot report any sophisticated physics via this API.
I did some google-images research and tried to provide definitions that
work with all common devices. That's why I went with 4 toms, 4 cymbals,
one bass, one hi-hat. I haven't seen other drums and I doubt that we need
any additions to that. Anyway, the naming-scheme is intentionally done in
an extensible way.
For guitars, we support 5 frets (normally aligned vertically, compared to
the real horizontal layouts), a single strum-bar with up/down directions,
an optional fret-board and a whammy-bar.
Most of the devices provide pressure values so I went with ABS_* bits. If
we ever support devices which only provide digital input, we have to
decide whether to emulate pressure data or add additional BTN_* bits.
If someone is not familiar with these devices, here are two pictures which
provide almost all introduced interfaces (or try the given keywords
with a google-image search):

ICMPv6: treat dest unreachable codes 5 and 6 as EACCES, not EPROTO
RFC 4443 has defined two additional codes for ICMPv6 type 1 (destination
unreachable) messages:
5 - Source address failed ingress/egress policy
6 - Reject route to destination
Now they are treated as protocol error and icmpv6_err_convert() converts them
to EPROTO.
RFC 4443 says:
"Codes 5 and 6 are more informative subsets of code 1."
Treat codes 5 and 6 as code 1 (EACCES)
Btw, connect() returning -EPROTO confuses firefox, so that fallback to
other/IPv4 addresses does not work:

John W. Linville says: ==================== Please accept this batch of updates intended for the 3.12 stream. For the mac80211 bits, Johannes says this: "This time I have various improvements all over the place: IBSS, mesh, testmode, AP client powersave handling, one of the rare rfkill patches and some code cleanup." Also for mac80211: "And I also have some more changes for -next, just a few small fixes and improvements, nothing really stands out." And for iwlwifi: "This time I have some powersave work (notably uAPSD support), CQM offloads, support for a new firmware API and various code cleanups." Regarding the Bluetooth bits, Gustavo says: "Patches to 3.12, here we have: * implementation of a proper tty_port for RFCOMM devices, this fixes some issues people were seeing lately in the kernel. * Add voice_setting option for SCO, it is used for SCO Codec selection * bugfixes, small improvements and clean ups" For the NFC bits, Samuel says: "With this one we have: - A few pn533 improvements and minor fixes. Testing our pn533 driver against Google's NCI stack triggered a few issues that we fixed now. We also added Tx fragmentation support to this driver. - More NFC secure element handling. We added a GET_SE netlink command for getting all the discovered secure elements, and we defined 2 additional secure element netlink event (transaction and connectivity). We also fixed a couple of typos and copy-paste bugs from the secure element handling code. - Firmware download support for the pn544 driver. This chipset can enter a special mode where it's waiting for firmware blobs to replace the already flashed one. We now support that mode." With repect to the ath tree, Kalle says: "New features in ath10k are rx/tx checsumming in hw and survey scan implemented by Michal. Also he made fixes to different areas of the driver, most notable being fixing the case when using two streams and reducing the number of interface combinations to avoid firmware crashes. Bartosz did a clean related to how we handle SoC power save in PCI layer. For ath6kl Mohammed and Vasanth sent each a patch to fix two infrequent crashes." I also pulled the wireless tree into wireless-next to support a request from Johannes. On top of all that, there are the usual sort of driver updates. The mwifiex, brcmfmac, brcmsmac, ath9k, and rt2x00 drivers all get some attention, as does the bcma bus and a few other random bits here and there. ==================== Signed-off-by: David S.

perf: Add a dummy software event to keep tracking
When an event is disabled the "tracking" events selected by the 'mmap', 'comm' and 'task' bits of struct perf_event_attr, are also disabled. However, the information those events provide is necessary to resolve symbols for when the main event is re-enabled. The "tracking" events can be kept enabled by putting them on another event, but that requires an event that otherwise does nothing. A new software event PERF_COUNT_SW_DUMMY is added for that purpose.

drm/radeon/si: Add support for CP DMA to CS checker for compute v2
Also add a new RADEON_INFO query to check that CP DMA packets are
supported on the compute ring.
CP DMA has been supported since the 3.8 kernel, but due to an oversight
we forgot to teach the CS checker that the CP DMA packet was legal for
the compute ring on Southern Islands GPUs.
This patch fixes a bug where the radeon driver will incorrectly reject a legal
CP DMA packet from user space. I would like to have the patch
backported to stable so that we don't have to require Mesa users to use a
bleeding edge kernel in order to take advantage of this feature which
is already present in the stable kernels (3.8 and newer).
v2:
- Don't bump kms version, so this patch can be backported to stable
kernels.

pkt_sched: fq: Fair Queue packet scheduler
- Uses perfect flow match (not stochastic hash like SFQ/FQ_codel)
- Uses the new_flow/old_flow separation from FQ_codel
- New flows get an initial credit allowing IW10 without added delay.
- Special FIFO queue for high prio packets (no need for PRIO + FQ)
- Uses a hash table of RB trees to locate the flows at enqueue() time
- Smart on demand gc (at enqueue() time, RB tree lookup evicts old
unused flows)
- Dynamic memory allocations.
- Designed to allow millions of concurrent flows per Qdisc.
- Small memory footprint : ~8K per Qdisc, and 104 bytes per flow.
- Single high resolution timer for throttled flows (if any).
- One RB tree to link throttled flows.
- Ability to have a max rate per flow. We might add a socket option
to add per socket limitation.
Attempts have been made to add TCP pacing in TCP stack, but this
seems to add complex code to an already complex stack.
TCP pacing is welcomed for flows having idle times, as the cwnd
permits TCP stack to queue a possibly large number of packets.
This removes the 'slow start after idle' choice, hitting badly
large BDP flows, and applications delivering chunks of data
as video streams.
Nicely spaced packets :
Here interface is 10Gbit, but flow bottleneck is ~20Mbit
cwin is big, yet FQ avoids the typical bursts generated by TCP
(as in netperf TCP_RR -- -r 100000,100000)

TCP timestamps show that most packets from B were queued in the same ms
timeframe (TSval 1159799{3,4}), but FQ managed to send them right
in time to avoid a big burst.
In slow start or steady state, very few packets are throttled [1]
FQ gets a bunch of tunables as :
limit : max number of packets on whole Qdisc (default 10000)
flow_limit : max number of packets per flow (default 100)
quantum : the credit per RR round (default is 2 MTU)
initial_quantum : initial credit for new flows (default is 10 MTU)
maxrate : max per flow rate (default : unlimited)
buckets : number of RB trees (default : 1024) in hash table.
(consumes 8 bytes per bucket)
[no]pacing : disable/enable pacing (default is enable)
All of them can be changed on a live qdisc.
$ tc qd add dev eth0 root fq help
Usage: ... fq [ limit PACKETS ] [ flow_limit PACKETS ]

backlog 0b 0p requeues 14
511 flows, 511 inactive, 0 throttled
110 gc, 0 highprio, 0 retrans, 1143 throttled, 0 flows_plimit
[1] Except if initial srtt is overestimated, as if using
cached srtt in tcp metrics. We'll provide a fix for this issue.

Usually the received CAN frames can be processed/routed as much as 'max_hops' times (which is given at module load time of the can-gw module). Introduce a new configuration option to reduce the number of possible hops for a specific gateway rule to a value smaller then max_hops.

perf: make events stream always parsable
The event stream is not always parsable because the format of a sample is dependent on the sample_type of the selected event. When there is more than one selected event and the sample_types are not the same then parsing becomes problematic. A sample can be matched to its selected event using the ID that is allocated when the event is opened. Unfortunately, to get the ID from the sample means first parsing it. This patch adds a new sample format bit PERF_SAMPLE_IDENTIFER that puts the ID at a fixed position so that the ID can be retrieved without parsing the sample. For sample events, that is the first position immediately after the header. For non-sample events, that is the last position. In this respect parsing samples requires that the sample_type and ID values are recorded. For example, perf tools records struct perf_event_attr and the IDs within the perf.data file. Those must be read first before it is possible to parse samples found later in the perf.data file.
