This includes two new updates for the ftrace infrastructure.
1) With the changing of the code for filtering events by pid, from
a list of pids to a bitmask, we can now easily implement following
forks. With a new tracing option "event-fork" which, when set, will
have tasks with pids in set_event_pid, when they fork, to have their
child pids added to set_event_pid and the child will be traced as well.
Note, if "event-fork" is set and a task with its pid in set_event_pid
exits, its pid will be removed from set_event_pid
2) The addition of Tom Zanussi's hist triggers. This includes a very
thorough documentatino on how to use the hist triggers with events.
This introduces a quick and easy way to get histogram data from
events and their fields.
Some other cleanups and updates were added as well. Like Masami Hiramatsu
added test cases for the event trigger and hist triggers. Also I added
a speed up of filtering by using a temp buffer when filters are set.

the iBFT header) and OEM_TABLE_ID (also whatever it extracts from

ARM: SoC driver updates for v4.7
Driver updates for ARM SoCs, these contain various things that touch the drivers/ directory but got merged through arm-soc for practical reasons. For the most part, this is now related to power management controllers, which have not yet been abstracted into a separate subsystem, and typically require some code in drivers/soc or arch/arm to control the power domains. Another large chunk here is a rework of the NVIDIA Tegra USB3.0 support, which was surprisingly tricky and took a long time to get done. Finally, reset controller handling as always gets merged through here as well. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAVzuXkGCrR//JCVInAQKb5BAAv2HuJ/tDjC8nNfYi0/aIt4uaRfRWE84t +nIpdKl/pB9AQo+HdG9WNihHs2GN44PdQRrDZ1enQX8nvTzc+dUl0AI1GZmUDpF/ zCV2UJ39HMZcEPwf8lZk9X/JP4VOkJDM5pDgNZnnqdvkq0oqtKzmh0Kt6m2g6fIS LR3FVtCRxJDeT+pT+EpoN4jpW0cb3mjTWbn/a8Ar3BH07KBA3U22MVJhHArLjS30 /aXP+AkgdvlgmBher5z44N6Qd/KOLn78rnE4LCRC4FwSCqA+qqPJQNGNblV5MHjE s5CYTqlihqLiGapqJ4zGBhmqj0XU/3kFVboGqYlTGjzMkOFgjddTpMdfkBUoG5oJ UubJ51zzSLXTcMwILGNXVls4YjJRKwNH7jeSjuMqpWrAYP4qBcMn/HQ1GqUjkNv+ yWkheHiLDYgYkIDOBDuFUtJ7OXiVumGGxIE+r2K/sXeNI7gFcDxFExMIo11vPAWP WJ8ydTchyb/RUQbzhjEXhoIeCZwXQfe9s11qsyFQDCZLleWYQGs3gFKdEI1E7+BE oe018BSP+uaVXdaV18Ne4smwzydLAU9/ieUoO45PAUSN2reV4lWhFTlNiiiMd3Id IWoYwpxqP2VW9zJvLz6QGF/P+3cZ00m/1lecJCKHHPBmbUijCHWJmgLT73AdSXmR YIJ2UM5QMiY= =x+iD -----END PGP SIGNATURE----- Merge tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver updates from Arnd Bergmann: "Driver updates for ARM SoCs, these contain various things that touch the drivers/ directory but got merged through arm-soc for practical reasons.

ARM: 64-bit DT updates for v4.7

The LG1312 platform is completely new and is the first ARM platform by LG that we support in the mainline kernel. Two other SoCs got added that are updated versions of existing SoC families, so the port mainly consists of new dts files: - The Hisilicon Hip06/D03 is the latest server platform from Huawei/Hisilicon, and follows the Hip05/D02 platform. - Rockchip RK3399 follows the 32-bit RK3288 that is popular in low-end Chromebooks and the 64-bit RK3368 that is mainly found in chinese Android TV boxes. The 96Boards HiKey based on the Hisilicon Hi6220 (Kirin 620) gets a long-awaited overhaul with a lot of devices enabled in the DT, so it should be much more usable with a mainline kernel now.

ARM: DT updates for v4.7
These are all the updates to device tree files for 32-bit platforms,
which as usual makes up the bulk of the ARM SoC changes: 462 non-merge
changesets, 450 files changed, 23340 insertions, 5216 deletions.
The three platforms that are added with the "soc" branch are here as well,

ARM: SoC platform updates for v4.7
We get support for three new 32-bit SoC platforms this time. The amount of changes in arch/arm for any of them is miniscule, as all the interesting code is in device driver subsystems (irqchip, clk, pinctrl, ...) these days. I'm listing them here, as the addition of the Kconfig statement is the main relevant milestone for a new platform. In each case, some drivers are are shared with existing platforms, while other drivers are added for v4.7 as well, or come in a later release. - The Aspeed platform is probably the most interesting one, this is what most whitebox servers use as their baseboard management controller. We get support for the very common ast2400 and ast2500 SoCs. The OpenBMC project focuses on this chip, and the LWN article about their ELC 2016 presentation at https://lwn.net/Articles/683320/ triggered the submission, but the code comes from IBM's OpenPOWER team rather than the team at Facebook. There are still a lot more drivers that need to get added over time, and I hope both teams can work together on that. - OXNAS is an old platform for Network Attached Storage devices from Oxford Semiconductor. There are models with ARM10 (!) and ARM11MPCore cores, but for now, we only support the original ARM9 based versions. The product lineup was subsequently part of PLX, Avago and now the new Broadcom Ltd. https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas has some more information. - V2M-MPS2 is a prototyping platform from ARM for their Cortex-M cores and is related to the existing Realview / Versatile Express lineup, but without MMU. We now support various NOMMU platforms, so adding a new one is fairly straightforward. http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/ has detailed information about the platform. Other noteworthy updates: - Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain Lemieux are now maintaining the platform. This is an older ARM9 based platform from NXP (not Freescale), but it remains in use in embedded markets. - Kevin Hilman is now co-maintaining the Amlogic Meson platform for both 32-bit and 64-bit ARM, and started contributing some patches. - As is often the case, work on the OMAP platforms makes up the bulk of the actual SoC code changes in arch/arm, but there isn't a lot of that either. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAVzuXX2CrR//JCVInAQLTghAA0f+2V2wC6HVBfDhT1YmhbAkPF1KzgLbB h30fN6BtIe9mE3kR69uWgwPSzn4hTKEQXoC9m6S+XClTn6MKPrbCEYDZl4ZwIER8 XDamxJV+6oTG+GKtKpHFkC4WPJkLthEuD34gr2xU8DFrU+y2Y5QNXi5wvSsBp8WS 6C/70HQEy35uSyOjbjVlPi0/UKoelVw9dCO7HZBOb9lTd88hC4Gx90KFwpq6Ievf L20VNgOESC2y6kRbuLNbhQVsbT2Ijyz9NccVM5owFEbHkXDxJ0vQVzrNM999DVjb CC2v0NZMLPNJQn2RvC172QBOsOERxIRkZdJHcifydl7i2QNpr8+/YSnS7OSx3dA/ 3ZmTLejaiGUXdTGEI9dHy77s+adwTzGsH+INKotQG8qwUXzCLuUWN3GGK+Qof5Rk jbsGAoZ7GQz1/7NdEOcGW6pxD4mllk3McKMzNlMmddRDUPhSUg3WXu0c1AWGzfA1 ulk6fQDaTUjvs7nokuozhguKz8OKrT6S7x/iES5tPbXLhuDqfnUdYiQ+7m2beRb5 L9S9KK95HXnKJAI9WLOELj1vCrfbCGjlwz8YVSrwPtwwzP/wbB1Ni6tmwLrxHbLk SGyJEMnPs3mARIPDwDysyOs+3OUSx04uYW6YTSh8XyKNIxTCflRxr/iM5YyYEMvt lXMrp1sh4hc= =5oFu -----END PGP SIGNATURE----- Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates from Arnd Bergmann: "We get support for three new 32-bit SoC platforms this time.

This is the bulk of GPIO changes for kernel cycle v4.7:
Core infrastructural changes:
- Support for natively single-ended GPIO driver stages. This
means that if the hardware has registers to configure open
drain or open source configuration, we use that rather than
(as we did before) try to emulate it by switching the line
to an input to get high impedance. This is also documented
throughly in Documentation/gpio/driver.txt for those of you
who did not understand one word of what I just wrote.
- Start to do away with the unnecessarily complex and
unitelligible ARCH_REQUIRE_GPIOLIB and
ARCH_WANT_OPTIONAL_GPIOLIB, another evolutional artifact from
the time when the GPIO subsystem was unmaintained. Archs can
now just select GPIOLIB and be done with it, cleanups to
arches will trickle in for the next kernel. Some minor archs
ACKed the changes immediately so these are included in this
pull request.
- Advancing the use of the data pointer inside the GPIO device
for storing driver data by switching the PowerPC, Super-H
Unicore and a few other subarches or subsystem drivers in
ALSA SoC, Input, serial, SSB, staging etc to use it.
- The initialization now reads the input/output state of the
GPIO lines, so that each GPIO descriptor knows - if this
callback is implemented - whether the line is input or
output. This also reflects nicely in userspace "lsgpio".
- It is now possible to name GPIO producer names, line names,
from the device tree. (Platform data has been supported for
a while.) I bet we will get a similar mechanism for ACPI
one of those days. This makes is possible to get sensible
producer names for e.g. GPIO rails in "lsgpio" in userspace.
New drivers:
- New driver for the Loongson1.
- The XLP driver now supports Broadcom Vulcan ARM64.
- The IT87 driver now supports IT8620 and IT8628.
- The PCA953X driver now supports Galileo Gen2.
Driver improvements:
- MCP23S08 was switched to use the gpiolib irqchip helpers and
now also suppors level-triggered interrupts.
- 74x164 and RCAR now supports the .set_multiple() callback
- AMDPT was converted to use generic GPIO.
- TC3589x, TPS65218, SX150X, F7188X, MENZ127, VX855, WM831X, WM8994
support the new single ended callback for open drain
and in some cases open source.
- Implement the .get_direction() callback for a few more drivers
like PL061, Xgene.
Cleanups:
- Paul Gortmaker combed through the drivers and de-modularized
those who are not really modules.
- Move the GPIO poweroff DT bindings to the power subdir where
they belong.
- Rename gpio-generic.c to gpio-mmio.c, which is much more to the
point. That's what it is handling, nothing more, nothing less.

Pull parallel filesystem directory handling update from Al Viro.
This is the main parallel directory work by Al that makes the vfs layer
able to do lookup and readdir in parallel within a single directory.
That's a big change, since this used to be all protected by the
directory inode mutex.
The inode mutex is replaced by an rwsem, and serialization of lookups of
a single name is done by a "in-progress" dentry marker.
The series begins with xattr cleanups, and then ends with switching
filesystems over to actually doing the readdir in parallel (switching to
the "iterate_shared()" that only takes the read lock).
A more detailed explanation of the process from Al Viro:
"The xattr work starts with some acl fixes, then switches ->getxattr to
passing inode and dentry separately. This is the point where the
things start to get tricky - that got merged into the very beginning
of the -rc3-based #work.lookups, to allow untangling the
security_d_instantiate() mess. The xattr work itself proceeds to
switch a lot of filesystems to generic_...xattr(); no complications
there.
After that initial xattr work, the series then does the following:
- untangle security_d_instantiate()
- convert a bunch of open-coded lookup_one_len_unlocked() to calls of
that thing; one such place (in overlayfs) actually yields a trivial
conflict with overlayfs fixes later in the cycle - overlayfs ended
up switching to a variant of lookup_one_len_unlocked() sans the
permission checks. I would've dropped that commit (it gets
overridden on merge from #ovl-fixes in #for-next; proper resolution
is to use the variant in mainline fs/overlayfs/super.c), but I
didn't want to rebase the damn thing - it was fairly late in the
cycle...
- some filesystems had managed to depend on lookup/lookup exclusion
for *fs-internal* data structures in a way that would break if we
relaxed the VFS exclusion. Fixing hadn't been hard, fortunately.
- core of that series - parallel lookup machinery, replacing
->i_mutex with rwsem, making lookup_slow() take it only shared. At
that point lookups happen in parallel; lookups on the same name
wait for the in-progress one to be done with that dentry.
Surprisingly little code, at that - almost all of it is in
fs/dcache.c, with fs/namei.c changes limited to lookup_slow() -
making it use the new primitive and actually switching to locking
shared.
- parallel readdir stuff - first of all, we provide the exclusion on
per-struct file basis, same as we do for read() vs lseek() for
regular files. That takes care of most of the needed exclusion in
readdir/readdir; however, these guys are trickier than lookups, so
I went for switching them one-by-one. To do that, a new method
'->iterate_shared()' is added and filesystems are switched to it
as they are either confirmed to be OK with shared lock on directory
or fixed to be OK with that. I hope to kill the original method
come next cycle (almost all in-tree filesystems are switched
already), but it's still not quite finished.
- several filesystems get switched to parallel readdir. The
interesting part here is dealing with dcache preseeding by readdir;
that needs minor adjustment to be safe with directory locked only
shared.
Most of the filesystems doing that got switched to in those
commits. Important exception: NFS. Turns out that NFS folks, with
their, er, insistence on VFS getting the fuck out of the way of the
Smart Filesystem Code That Knows How And What To Lock(tm) have
grown the locking of their own. They had their own homegrown
rwsem, with lookup/readdir/atomic_open being *writers* (sillyunlink
is the reader there). Of course, with VFS getting the fuck out of
the way, as requested, the actual smarts of the smart filesystem
code etc. had become exposed...
- do_last/lookup_open/atomic_open cleanups. As the result, open()
without O_CREAT locks the directory only shared. Including the
->atomic_open() case. Backmerge from #for-linus in the middle of
that - atomic_open() fix got brought in.
- then comes NFS switch to saner (VFS-based ;-) locking, killing the
homegrown "lookup and readdir are writers" kinda-sorta rwsem. All
exclusion for sillyunlink/lookup is done by the parallel lookups
mechanism. Exclusion between sillyunlink and rmdir is a real rwsem
now - rmdir being the writer.
Result: NFS lookups/readdirs/O_CREAT-less opens happen in parallel
now.
- the rest of the series consists of switching a lot of filesystems
to parallel readdir; in a lot of cases ->llseek() gets simplified
as well. One backmerge in there (again, #for-linus - rockridge
fix)"

Pull power management updates from Rafael Wysocki:
"The majority of changes go into the cpufreq subsystem this time.
To me, quite obviously, the biggest ticket item is the new "schedutil"
governor. Interestingly enough, it's the first new cpufreq governor
since the beginning of the git era (except for some out-of-the-tree
ones).
There are two main differences between it and the existing governors.
First, it uses the information provided by the scheduler directly for
making its decisions, so it doesn't have to track anything by itself.
Second, it can invoke drivers (supporting that feature) to adjust CPU
performance right away without having to spawn work items to be
executed in process context or similar. Currently, the acpi-cpufreq
driver is the only one supporting that mode of operation, but then it
is used on a large number of systems.
The "schedutil" governor as included here is very simple and mostly
regarded as a foundation for future work on the integration of the
scheduler with CPU power management (in fact, there is work in
progress on top of it already). Nevertheless it works and the
preliminary results obtained with it are encouraging.
There also is some consolidation of CPU frequency management for ARM
platforms that can add their machine IDs the the new stub dt-platdev
driver now and that will take care of creating the requisite platform
device for cpufreq-dt, so it is not necessary to do that in platform
code any more. Several ARM platforms are switched over to using this
generic mechanism.
In addition to that, the intel_pstate driver is now going to respect
CPU frequency limits set by the platform firmware (or a BMC) and
provided via the ACPI _PPC object.
The devfreq subsystem is getting a new "passive" governor for SoCs
subsystems that will depend on somebody else to manage their voltage
rails and its support for Samsung Exynos SoCs is consolidated.
The rest is support for new hardware (Intel Broxton support in
intel_idle for one example), bug fixes, optimizations and cleanups in
a number of places.

utilization information provided by the scheduler and capable of
switching CPU frequencies right away if the underlying driver

regulator: Updates for v4.7
A few core enhancements to deal with some of the slightly more
complicated edge cases that have started cropping up in systems, both
new ones and old ones that people started worrying about upstream, but
otherwise a quiet release for the regulator API:
- When applying constraints at system image if we have a voltage range
specified and the regulator is currently configured outside the
bounds of that range bring the regulator to the nearest end of the
range.
- When regulators are in non-regulating bypass modes make sure that we
always use the voltage from the parent regulator.
- Support for LP873x, PV88080, PM8894 and FAN53555 chips.

bpf: add generic constant blinding for use in jits
This work adds a generic facility for use from eBPF JIT compilers that allows for further hardening of JIT generated images through blinding constants. In response to the original work on BPF JIT spraying published by Keegan McAllister [1], most BPF JITs were changed to make images read-only and start at a randomized offset in the page, where the rest was filled with trap instructions. We have this nowadays in x86, arm, arm64 and s390 JIT compilers. Additionally, later work also made eBPF interpreter images read only for kernels supporting DEBUG_SET_MODULE_RONX, that is, x86, arm, arm64 and s390 archs as well currently. This is done by default for mentioned JITs when JITing is enabled. Furthermore, we had a generic and configurable constant blinding facility on our todo for quite some time now to further make spraying harder, and first implementation since around netconf 2016. We found that for systems where untrusted users can load cBPF/eBPF code where JIT is enabled, start offset randomization helps a bit to make jumps into crafted payload harder, but in case where larger programs that cross page boundary are injected, we again have some part of the program opcodes at a page start offset. With improved guessing and more reliable payload injection, chances can increase to jump into such payload. Elena Reshetova recently wrote a test case for it [2, 3]. Moreover, eBPF comes with 64 bit constants, which can leave some more room for payloads. Note that for all this, additional bugs in the kernel are still required to make the jump (and of course to guess right, to not jump into a trap) and naturally the JIT must be enabled, which is disabled by default. For helping mitigation, the general idea is to provide an option bpf_jit_harden that admins can tweak along with bpf_jit_enable, so that for cases where JIT should be enabled for performance reasons, the generated image can be further hardened with blinding constants for unpriviledged users (bpf_jit_harden == 1), with trading off performance for these, but not for privileged ones. We also added the option of blinding for all users (bpf_jit_harden == 2), which is quite helpful for testing f.e. with test_bpf.ko. There are no further e.g. hardening levels of bpf_jit_harden switch intended, rationale is to have it dead simple to use as on/off. Since this functionality would need to be duplicated over and over for JIT compilers to use, which are already complex enough, we provide a generic eBPF byte-code level based blinding implementation, which is then just transparently JITed. JIT compilers need to make only a few changes to integrate this facility and can be migrated one by one. This option is for eBPF JITs and will be used in x86, arm64, s390 without too much effort, and soon ppc64 JITs, thus that native eBPF can be blinded as well as cBPF to eBPF migrations, so that both can be covered with a single implementation. The rule for JITs is that bpf_jit_blind_constants() must be called from bpf_int_jit_compile(), and in case blinding is disabled, we follow normally with JITing the passed program. In case blinding is enabled and we fail during the process of blinding itself, we must return with the interpreter. Similarly, in case the JITing process after the blinding failed, we return normally to the interpreter with the non-blinded code. Meaning, interpreter doesn't change in any way and operates on eBPF code as usual. For doing this pre-JIT blinding step, we need to make use of a helper/auxiliary register, here BPF_REG_AX. This is strictly internal to the JIT and not in any way part of the eBPF architecture. Just like in the same way as JITs internally make use of some helper registers when emitting code, only that here the helper register is one abstraction level higher in eBPF bytecode, but nevertheless in JIT phase. That helper register is needed since f.e. manually written program can issue loads to all registers of eBPF architecture. The core concept with the additional register is: blind out all 32 and 64 bit constants by converting BPF_K based instructions into a small sequence from K_VAL into ((RND ^ K_VAL) ^ RND). Therefore, this is transformed into: BPF_REG_AX := (RND ^ K_VAL), BPF_REG_AX ^= RND, and REG <OP> BPF_REG_AX, so actual operation on the target register is translated from BPF_K into BPF_X one that is operating on BPF_REG_AX's content. During rewriting phase when blinding, RND is newly generated via prandom_u32() for each processed instruction. 64 bit loads are split into two 32 bit loads to make translation and patching not too complex. Only basic thing required by JITs is to call the helper bpf_jit_blind_constants()/bpf_jit_prog_release_other() pair, and to map BPF_REG_AX into an unused register. Small bpf_jit_disasm extract from [2] when applied to x86 JIT: echo 0 > /proc/sys/net/core/bpf_jit_harden ffffffffa034f5e9 + <x>: [...] 39: mov $0xa8909090,%eax 3e: mov $0xa8909090,%eax 43: mov $0xa8ff3148,%eax 48: mov $0xa89081b4,%eax 4d: mov $0xa8900bb0,%eax 52: mov $0xa810e0c1,%eax 57: mov $0xa8908eb4,%eax 5c: mov $0xa89020b0,%eax [...] echo 1 > /proc/sys/net/core/bpf_jit_harden ffffffffa034f1e5 + <x>: [...] 39: mov $0xe1192563,%r10d 3f: xor $0x4989b5f3,%r10d 46: mov %r10d,%eax 49: mov $0xb8296d93,%r10d 4f: xor $0x10b9fd03,%r10d 56: mov %r10d,%eax 59: mov $0x8c381146,%r10d 5f: xor $0x24c7200e,%r10d 66: mov %r10d,%eax 69: mov $0xeb2a830e,%r10d 6f: xor $0x43ba02ba,%r10d 76: mov %r10d,%eax 79: mov $0xd9730af,%r10d 7f: xor $0xa5073b1f,%r10d 86: mov %r10d,%eax 89: mov $0x9a45662b,%r10d 8f: xor $0x325586ea,%r10d 96: mov %r10d,%eax [...] As can be seen, original constants that carry payload are hidden when enabled, actual operations are transformed from constant-based to register-based ones, making jumps into constants ineffective. Above extract/example uses single BPF load instruction over and over, but of course all instructions with constants are blinded. Performance wise, JIT with blinding performs a bit slower than just JIT and faster than interpreter case. This is expected, since we still get all the performance benefits from JITing and in normal use-cases not every single instruction needs to be blinded. Summing up all 296 test cases averaged over multiple runs from test_bpf.ko suite, interpreter was 55% slower than JIT only and JIT with blinding was 8% slower than JIT only. Since there are also some extremes in the test suite, I expect for ordinary workloads that the performance for the JIT with blinding case is even closer to JIT only case, f.e. nmap test case from suite has averaged timings in ns 29 (JIT), 35 (+ blinding), and 151 (interpreter). BPF test suite, seccomp test suite, eBPF sample code and various bigger networking eBPF programs have been tested with this and were running fine. For testing purposes, I also adapted interpreter and redirected blinded eBPF image to interpreter and also here all tests pass.

ibft: Expose iBFT acpi header via sysfs
Some ethernet adapter vendors are supplying products which support optional (payed license) features. On some adapters this includes a hardware iscsi initiator. The same adapters in a normal (no extra licenses) mode of operation can be used as a software iscsi initiator. In addition, software iscsi boot initiators are becoming a standard part of many vendors uefi implementations. This is creating difficulties during early boot/install determining the proper configuration method for these adapters when they are used as a boot device. The attached patch creates sysfs entries to expose information from the acpi header of the ibft table. This information allows for a method to easily determining if an ibft table was created by a ethernet card's firmware or the system uefi/bios. In the case of a hardware initiator this information in combination with the pci vendor and device id can be used to ascertain any vendor specific behaviors that need to be accommodated.
