fsnotify: rename event handling functions
Rename fsnotify_add_notify_event() to fsnotify_add_event() since the "notify" part is duplicit. Rename fsnotify_remove_notify_event() and fsnotify_peek_notify_event() to fsnotify_remove_first_event() and fsnotify_peek_first_event() respectively since "notify" part is duplicit and they really look at the first event in the queue.

"A rather large update of timers, timekeeping & co
- Core timekeeping code is year-2038 safe now for 32bit machines.
Now we just need to fix all in kernel users and the gazillion of
user space interfaces which rely on timespec/timeval :)
- Better cache layout for the timekeeping internal data structures.
- Proper nanosecond based interfaces for in kernel users.
- Tree wide cleanup of code which wants nanoseconds but does hoops
and loops to convert back and forth from timespecs. Some of it
definitely belongs into the ugly code museum.
- Consolidation of the timekeeping interface zoo.
- A fast NMI safe accessor to clock monotonic for tracing. This is a
long standing request to support correlated user/kernel space
traces. With proper NTP frequency correction it's also suitable
for correlation of traces accross separate machines.
- Checkpoint/restart support for timerfd.
- A few NOHZ[_FULL] improvements in the [hr]timer code.
- Code move from kernel to kernel/time of all time* related code.
- New clocksource/event drivers from the ARM universe. I'm really
impressed that despite an architected timer in the newer chips SoC
manufacturers insist on inventing new and differently broken SoC
specific timers.
[ Ed. "Impressed"? I don't think that word means what you think it means ]
- Another round of code move from arch to drivers. Looks like most
of the legacy mess in ARM regarding timers is sorted out except for
a few obnoxious strongholds.
- The usual updates and fixlets all over the place"

net-timestamp: ACK timestamp for bytestreams
Add SOF_TIMESTAMPING_TX_ACK, a request for a tstamp when the last byte in the send() call is acknowledged. It implements the feature for TCP. The timestamp is generated when the TCP socket cumulative ACK is moved beyond the tracked seqno for the first time. The feature ignores SACK and FACK, because those acknowledge the specific byte, but not necessarily the entire contents of the buffer up to that byte.

net-timestamp: add key to disambiguate concurrent datagrams
Datagrams timestamped on transmission can coexist in the kernel stack and be reordered in packet scheduling. When reading looped datagrams from the socket error queue it is not always possible to unique correlate looped data with original send() call (for application level retransmits). Even if possible, it may be expensive and complex, requiring packet inspection. Introduce a data-independent ID mechanism to associate timestamps with send calls. Pass an ID alongside the timestamp in field ee_data of sock_extended_err. The ID is a simple 32 bit unsigned int that is associated with the socket and incremented on each send() call for which software tx timestamp generation is enabled. The feature is enabled only if SOF_TIMESTAMPING_OPT_ID is set, to avoid changing ee_data for existing applications that expect it 0. The counter is reset each time the flag is reenabled. Reenabling does not change the ID of already submitted data. It is possible to receive out of order IDs if the timestamp stream is not quiesced first.

net-timestamp: move timestamp flags out of sk_flags
sk_flags is reaching its limit. New timestamping options will not fit. Move all of them into a new field sk->sk_tsflags. Added benefit is that this removes boilerplate code to convert between SOF_TIMESTAMPING_.. and SOCK_TIMESTAMPING_.. in getsockopt/setsockopt. SOCK_TIMESTAMPING_RX_SOFTWARE is also used to toggle the receive timestamp logic (netstamp_needed). That can be simplified and this last key removed, but will leave that for a separate patch.

Applications that request kernel tx timestamps with SO_TIMESTAMPING read timestamps as recvmsg() ancillary data.

On tx, scm_timestamping always accompanies a sock_extended_err. Define previously unused field ee_info to signal the type of ts[0]. Introduce SCM_TSTAMP_SND to define the existing behavior. The reception path is not modified. On rx, no struct similar to sock_extended_err is passed along with SCM_TIMESTAMPING. Signed-off-by: Willem de Bruijn <willemb@google.com> Signed-off-by: David S.

tcp: reduce spurious retransmits due to transient SACK reneging
This commit reduces spurious retransmits due to apparent SACK reneging by only reacting to SACK reneging that persists for a short delay. When a sequence space hole at snd_una is filled, some TCP receivers send a series of ACKs as they apparently scan their out-of-order queue and cumulatively ACK all the packets that have now been consecutiveyly received. This is essentially misbehavior B in "Misbehaviors in TCP SACK generation" ACM SIGCOMM Computer Communication Review, April 2011, so we suspect that this is from several common OSes (Windows 2000, Windows Server 2003, Windows XP). However, this issue has also been seen in other cases, e.g. the netdev thread "TCP being hoodwinked into spurious retransmissions by lack of timestamps?" from March 2014, where the receiver was thought to be a BSD box. Since snd_una would temporarily be adjacent to a previously SACKed range in these scenarios, this receiver behavior triggered the Linux SACK reneging code path in the sender. This led the sender to clear the SACK scoreboard, enter CA_Loss, and spuriously retransmit (potentially) every packet from the entire write queue at line rate just a few milliseconds before the ACK for each packet arrives at the sender. To avoid such situations, now when a sender sees apparent reneging it does not yet retransmit, but rather adjusts the RTO timer to give the receiver a little time (max(RTT/2, 10ms)) to send us some more ACKs that will restore sanity to the SACK scoreboard. If the reneging persists until this RTO then, as before, we clear the SACK scoreboard and enter CA_Loss. A 10ms delay tolerates a receiver sending such a stream of ACKs at 56Kbit/sec. And to allow for receivers with slower or more congested paths, we wait for at least RTT/2. We validated the resulting max(RTT/2, 10ms) delay formula with a mix of North American and South American Google web server traffic, and found that for ACKs displaying transient reneging: (1) 90% of inter-ACK delays were less than 10ms (2) 99% of inter-ACK delays were less than RTT/2 In tests on Google web servers this commit reduced reneging events by 75%-90% (as measured by the TcpExtTCPSACKReneging counter), without any measurable impact on latency for user HTTP and SPDY requests.

regulator: Updates for v3.17
A couple of nice new features this month, the ability to map regulators
in order to allow voltage control by external coprocessors is something
people have been asking for for a long time.
- Improved support for switch only "regulators", allowing current state
to be read from the parent regulator but no setting.
- Support for obtaining the register access method used to set
voltages, for use in systems which can offload control of this to a
coprocessor (typically for DVFS).
- Support for Active-Semi AC8846, Dialog DA9211 and Texas Instruments

spi: Updates for v3.17
A quiet release, more bug fixes than anything else. A few things do
stand out though:
- Updates to several drivers to move towards the standard GPIO chip
select handling in the core.
- DMA support for the SH MSIOF driver.
- Support for Rockchip SPI controllers (their first mainline
submission).

random: introduce getrandom(2) system call
The getrandom(2) system call was requested by the LibreSSL Portable
developers. It is analoguous to the getentropy(2) system call in
OpenBSD.
The rationale of this system call is to provide resiliance against
file descriptor exhaustion attacks, where the attacker consumes all
available file descriptors, forcing the use of the fallback code where
/dev/[u]random is not available. Since the fallback code is often not
well-tested, it is better to eliminate this potential failure mode
entirely.
The other feature provided by this new system call is the ability to
request randomness from the /dev/urandom entropy pool, but to block
until at least 128 bits of entropy has been accumulated in the
/dev/urandom entropy pool. Historically, the emphasis in the
/dev/urandom development has been to ensure that urandom pool is
initialized as quickly as possible after system boot, and preferably
before the init scripts start execution.
This is because changing /dev/urandom reads to block represents an
interface change that could potentially break userspace which is not
acceptable. In practice, on most x86 desktop and server systems, in
general the entropy pool can be initialized before it is needed (and
in modern kernels, we will printk a warning message if not). However,
on an embedded system, this may not be the case. And so with this new
interface, we can provide the functionality of blocking until the
urandom pool has been initialized. Any userspace program which uses
this new functionality must take care to assure that if it is used
during the boot process, that it will not cause the init scripts or
other portions of the system startup to hang indefinitely.
SYNOPSIS
#include <linux/random.h>
int getrandom(void *buf, size_t buflen, unsigned int flags);
DESCRIPTION
The system call getrandom() fills the buffer pointed to by buf
with up to buflen random bytes which can be used to seed user
space random number generators (i.e., DRBG's) or for other
cryptographic uses. It should not be used for Monte Carlo
simulations or other programs/algorithms which are doing
probabilistic sampling.
If the GRND_RANDOM flags bit is set, then draw from the
/dev/random pool instead of the /dev/urandom pool. The
/dev/random pool is limited based on the entropy that can be
obtained from environmental noise, so if there is insufficient
entropy, the requested number of bytes may not be returned.
If there is no entropy available at all, getrandom(2) will
either block, or return an error with errno set to EAGAIN if
the GRND_NONBLOCK bit is set in flags.
If the GRND_RANDOM bit is not set, then the /dev/urandom pool
will be used. Unlike using read(2) to fetch data from
/dev/urandom, if the urandom pool has not been sufficiently
initialized, getrandom(2) will block (or return -1 with the
errno set to EAGAIN if the GRND_NONBLOCK bit is set in flags).
The getentropy(2) system call in OpenBSD can be emulated using
the following function:
int getentropy(void *buf, size_t buflen)
{
int ret;
if (buflen > 256)
goto failure;
ret = getrandom(buf, buflen, 0);
if (ret < 0)
return ret;
if (ret == buflen)
return 0;
failure:
errno = EIO;
return -1;
}
RETURN VALUE
On success, the number of bytes that was filled in the buf is
returned. This may not be all the bytes requested by the
caller via buflen if insufficient entropy was present in the
/dev/random pool, or if the system call was interrupted by a
signal.
On error, -1 is returned, and errno is set appropriately.
ERRORS
EINVAL An invalid flag was passed to getrandom(2)
EFAULT buf is outside the accessible address space.
EAGAIN The requested entropy was not available, and
getentropy(2) would have blocked if the
GRND_NONBLOCK flag was not set.
EINTR While blocked waiting for entropy, the call was
interrupted by a signal handler; see the description
of how interrupted read(2) calls on "slow" devices
are handled with and without the SA_RESTART flag
in the signal(7) man page.
NOTES
For small requests (buflen <= 256) getrandom(2) will not
return EINTR when reading from the urandom pool once the
entropy pool has been initialized, and it will return all of
the bytes that have been requested. This is the recommended
way to use getrandom(2), and is designed for compatibility
with OpenBSD's getentropy() system call.
However, if you are using GRND_RANDOM, then getrandom(2) may
block until the entropy accounting determines that sufficient
environmental noise has been gathered such that getrandom(2)
will be operating as a NRBG instead of a DRBG for those people
who are working in the NIST SP 800-90 regime. Since it may
block for a long time, these guarantees do *not* apply. The
user may want to interrupt a hanging process using a signal,
so blocking until all of the requested bytes are returned
would be unfriendly.
For this reason, the user of getrandom(2) MUST always check
the return value, in case it returns some error, or if fewer
bytes than requested was returned. In the case of
!GRND_RANDOM and small request, the latter should never
happen, but the careful userspace code (and all crypto code
should be careful) should check for this anyway!
Finally, unless you are doing long-term key generation (and
perhaps not even then), you probably shouldn't be using
GRND_RANDOM. The cryptographic algorithms used for
/dev/urandom are quite conservative, and so should be
sufficient for all purposes. The disadvantage of GRND_RANDOM
is that it can block, and the increased complexity required to
deal with partially fulfilled getrandom(2) requests.

Conflicts: net/6lowpan/iphc.c Minor conflicts in iphc.c were changes overlapping with some style cleanups. John W. Linville says: ==================== Please pull this last(?) batch of wireless change intended for the 3.17 stream... For the NFC bits, Samuel says: "This is a rather quiet one, we have: - A new driver from ST Microelectronics for their NCI ST21NFCB, including device tree support. - p2p support for the ST21NFCA driver - A few fixes an enhancements for the NFC digital laye" For the Atheros bits, Kalle says: "Michal and Janusz did some important RX aggregation fixes, basically we were missing RX reordering altogether. The 10.1 firmware doesn't support Ad-Hoc mode and Michal fixed ath10k so that it doesn't advertise Ad-Hoc support with that firmware. Also he implemented a workaround for a KVM issue." For the Bluetooth bits, Gustavo and Johan say: "To quote Gustavo from his previous request: 'Some last minute fixes for -next. We have a fix for a use after free in RFCOMM, another fix to an issue with ADV_DIRECT_IND and one for ADV_IND with auto-connection handling. Last, we added support for reading the codec and MWS setting for controllers that support these features.' Additionally there are fixes to LE scanning, an update to conform to the 4.1 core specification as well as fixes for tracking the page scan state. All of these fixes are important for 3.17." And, "We've got: - 6lowpan fixes/cleanups - A couple crash fixes, one for the Marvell HCI driver and another in LE SMP. - Fix for an incorrect connected state check - Fix for the bondable requirement during pairing (an issue which had crept in because of using "pairable" when in fact the actual meaning was "bondable" (these have different meanings in Bluetooth)" Along with those are some late-breaking hardware support patches in brcmfmac and b43 as well as a stray ath9k patch. ==================== Signed-off-by: David S.

arm64 updates for 3.17
Changes include:
- Context tracking support (NO_HZ_FULL) which narrowly missed 3.16
- vDSO layout rework following Andy's work on x86
- TEXT_OFFSET fuzzing for bootloader testing
- /proc/cpuinfo tidy-up
- Preliminary work to support 48-bit virtual addresses, but this is
currently disabled until KVM has been ported to use it (the patches
do, however, bring some nice clean-up)
- Boot-time CPU sanity checks (especially useful on heterogenous
systems)
- Support for syscall auditing
- Support for CC_STACKPROTECTOR
- defconfig updates

These are the x86, MIPS and s390 changes; PPC and ARM will come in a

This pull request has a lot of work done. The main thing is the changes
to the ftrace function callback infrastructure. It's introducing a way to allow different functions to call directly different trampolines instead of all calling the same "mcount" one. The only user of this for now is the function graph tracer, which always had a different trampoline, but the function tracer trampoline was called and did basically nothing, and then the function graph tracer trampoline was called. The difference now, is that the function graph tracer trampoline can be called directly if a function is only being traced by the function graph trampoline. If function tracing is also happening on the same function, the old way is still done. The accounting for this takes up more memory when function graph tracing is activated, as it needs to keep track of which functions it uses. I have a new way that wont take as much memory, but it's not ready yet for this merge window, and will have to wait for the next one. Another big change was the removal of the ftrace_start/stop() calls that were used by the suspend/resume code that stopped function tracing when entering into suspend and resume paths. The stop of ftrace was done because there was some function that would crash the system if one called smp_processor_id()! The stop/start was a big hammer to solve the issue at the time, which was when ftrace was first introduced into Linux. Now ftrace has better infrastructure to debug such issues, and I found the problem function and labeled it with "notrace" and function tracing can now safely be activated all the way down into the guts of suspend and resume. Other changes include clean ups of uprobe code. Clean up of the trace_seq() code. And other various small fixes and clean ups to ftrace and tracing. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJT35zXAAoJEKQekfcNnQGuOz0H/38zqM0nLFhrgvz3EPk2UOjn xqpX8qyb2V7TJZL+IqeXU2a5cQZl5ba0D4WtBGpxbTae3CJYiuQ87iKUNFoH0om5 FDpn80igb368k8V3qRdRsziKVCCf0XBd/NkHJXc0ZkfXGyzB2Ga4bBxALxp2gj9y bnO+vKo6+tWYKG4hyQb4P3LRXUrK8/LWEsPr39cH2QH1Rdj69Lx9CgrCdUVJmwcb Bj8hEiLXL/RYCFNn79A3wNTUvW0rG/AOIf4SLqXtasSRZ0ToaU0ZyDnrNv+0Ol47 rX8tSk+LfXchL9hpIvjCf1vlAYq3pO02favteR/jip3lx/dTjEDE4RJ9qtJzZ4Q= =fwQY -----END PGP SIGNATURE----- Merge tag 'trace-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: "This pull request has a lot of work done.

The clock framework changes for 3.17 are mostly additions of new clock
drivers and fixes/enhancements to existing clock drivers. There are also
some non-critical fixes and improvements to the framework core.
Changes to the clock framework core include:
* improvements to printks on errors
* flattening the previously hierarchal structure of per-clock entries
in debugfs
* allow per-clock debugfs entries that are specific to a particular
clock driver
* configure initial clock parent and/or initial clock rate from Device
Tree
* several feature enhancements to the composite clock type
* misc fixes
New clock drivers added include:
* TI Palmas PMIC
* Allwinner A23 SoC
* Qualcomm APQ8084 and IPQ8064 SoCs
* Rockchip rk3188, rk3066 and rk3288 SoCs
* STMicroelectronics STiH407 SoC
* Cirrus Logic CLPS711X SoC
Many fixes, feature enhancements and further clock tree support for
existing clock drivers also were merged, such as Samsung's "ARMCLK down"
power saving feature for their Exynos4 & Exynos5 SoCs.

Merge branch 'for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup changes from Tejun Heo:
"Mostly changes to get the v2 interface ready. The core features are
mostly ready now and I think it's reasonable to expect to drop the
devel mask in one or two devel cycles at least for a subset of
controllers.
- cgroup added a controller dependency mechanism so that block cgroup
can depend on memory cgroup. This will be used to finally support
IO provisioning on the writeback traffic, which is currently being
implemented.
- The v2 interface now uses a separate table so that the interface
files for the new interface are explicitly declared in one place.
Each controller will explicitly review and add the files for the
new interface.
- cpuset is getting ready for the hierarchical behavior which is in
the similar style with other controllers so that an ancestor's
configuration change doesn't change the descendants' configurations
irreversibly and processes aren't silently migrated when a CPU or
node goes down.
All the changes are to the new interface and no behavior changed for
the multiple hierarchies"
