ns: allow ns_entries to have custom symlink content
Patch series "Expose task pid_ns_for_children to userspace". pid_ns_for_children set by a task is known only to the task itself, and it's impossible to identify it from outside. It's a big problem for checkpoint/restore software like CRIU, because it can't correctly handle tasks, that do setns(CLONE_NEWPID) in proccess of their work. If they have a custom pid_ns_for_children before dump, they must have the same ns after restore. Otherwise, restored task bumped into enviroment it does not expect. This patchset solves the problem. It exposes pid_ns_for_children to ns directory in standard way with the name "pid_for_children": ~# ls /proc/5531/ns -l | grep pid lrwxrwxrwx 1 root root 0 Jan 14 16:38 pid -> pid:[4026531836] lrwxrwxrwx 1 root root 0 Jan 14 16:38 pid_for_children -> pid:[4026532286] This patch (of 2): Make possible to have link content prefix yyy different from the link name xxx: $ readlink /proc/[pid]/ns/xxx yyy:[4026531838] This will be used in next patch.

crash: move crashkernel parsing and vmcore related code under CONFIG_CRASH_CORE
Patch series "kexec/fadump: remove dependency with CONFIG_KEXEC and reuse crashkernel parameter for fadump", v4. Traditionally, kdump is used to save vmcore in case of a crash. Some architectures like powerpc can save vmcore using architecture specific support instead of kexec/kdump mechanism. Such architecture specific support also needs to reserve memory, to be used by dump capture kernel. crashkernel parameter can be a reused, for memory reservation, by such architecture specific infrastructure. This patchset removes dependency with CONFIG_KEXEC for crashkernel parameter and vmcoreinfo related code as it can be reused without kexec support. Also, crashkernel parameter is reused instead of fadump_reserve_mem to reserve memory for fadump. The first patch moves crashkernel parameter parsing and vmcoreinfo related code under CONFIG_CRASH_CORE instead of CONFIG_KEXEC_CORE. The second patch reuses the definitions of append_elf_note() & final_note() functions under CONFIG_CRASH_CORE in IA64 arch code. The third patch removes dependency on CONFIG_KEXEC for firmware-assisted dump (fadump) in powerpc. The next patch reuses crashkernel parameter for reserving memory for fadump, instead of the fadump_reserve_mem parameter. This has the advantage of using all syntaxes crashkernel parameter supports, for fadump as well. The last patch updates fadump kernel documentation about use of crashkernel parameter. This patch (of 5): Traditionally, kdump is used to save vmcore in case of a crash. Some architectures like powerpc can save vmcore using architecture specific support instead of kexec/kdump mechanism. Such architecture specific support also needs to reserve memory, to be used by dump capture kernel. crashkernel parameter can be a reused, for memory reservation, by such architecture specific infrastructure. But currently, code related to vmcoreinfo and parsing of crashkernel parameter is built under CONFIG_KEXEC_CORE. This patch introduces CONFIG_CRASH_CORE and moves the above mentioned code under this config, allowing code reuse without dependency on CONFIG_KEXEC. There is no functional change with this patch.

cpumask: make "nr_cpumask_bits" unsigned
Bit searching functions accept "unsigned long" indices but "nr_cpumask_bits" is "int" which is signed, so inevitable sign extensions occur on x86_64. Those MOVSX are #1 MOVSX bloat by number of uses across whole kernel. Change "nr_cpumask_bits" to unsigned, this number can't be negative after all. It allows to do implicit zero-extension on x86_64 without MOVSX. Change signed comparisons into unsigned comparisons where necessary. Other uses looks fine because it is either argument passed to a function or comparison is already unsigned.

mm, page_alloc: count movable pages when stealing from pageblock
When stealing pages from pageblock of a different migratetype, we count how many free pages were stolen, and change the pageblock's migratetype if more than half of the pageblock was free. This might be too conservative, as there might be other pages that are not free, but were allocated with the same migratetype as our allocation requested. While we cannot determine the migratetype of allocated pages precisely (at least without the page_owner functionality enabled), we can count pages that compaction would try to isolate for migration - those are either on LRU or __PageMovable(). The rest can be assumed to be MIGRATE_RECLAIMABLE or MIGRATE_UNMOVABLE, which we cannot easily distinguish. This counting can be done as part of free page stealing with little additional overhead. The page stealing code is changed so that it considers free pages plus pages of the "good" migratetype for the decision whether to change pageblock's migratetype. The result should be more accurate migratetype of pageblocks wrt the actual pages in the pageblocks, when stealing from semi-occupied pageblocks. This should help the efficiency of page grouping by mobility. In testing based on 4.9 kernel with stress-highalloc from mmtests configured for order-4 GFP_KERNEL allocations, this patch has reduced the number of unmovable allocations falling back to movable pageblocks by 47%. The number of movable allocations falling back to other pageblocks are increased by 55%, but these events don't cause permanent fragmentation, so the tradeoff should be positive. Later patches also offset the movable fallback increase to some extent.

ipv6: reorder ip6_route_dev_notifier after ipv6_dev_notf
For each netns (except init_net), we initialize its null entry
in 3 places:
1) The template itself, as we use kmemdup()
2) Code around dst_init_metrics() in ip6_route_net_init()
3) ip6_route_dev_notify(), which is supposed to initialize it after
loopback registers
Unfortunately the last one still happens in a wrong order because
we expect to initialize net->ipv6.ip6_null_entry->rt6i_idev to
net->loopback_dev's idev, thus we have to do that after we add
idev to loopback. However, this notifier has priority == 0 same as
ipv6_dev_notf, and ipv6_dev_notf is registered after
ip6_route_dev_notifier so it is called actually after
ip6_route_dev_notifier. This is similar to commit

tcp: make congestion control optionally skip slow start after idle
Congestion control modules that want full control over congestion
control behavior do not want the cwnd modifications controlled by
the sysctl_tcp_slow_start_after_idle code path.
So skip those code paths for CC modules that use the cong_control()
API.
As an example, those cwnd effects are not desired for the BBR congestion
control algorithm.

ipv4: restore rt->fi for reference counting
IPv4 dst could use fi->fib_metrics to store metrics but fib_info itself is refcnt'ed, so without taking a refcnt fi and fi->fib_metrics could be freed while dst metrics still points to it. This triggers use-after-free as reported by Andrey twice. This patch reverts commit |

block, dax: move "select DAX" from BLOCK to FS_DAX
For configurations that do not enable DAX filesystems or drivers, do not require the DAX core to be built. Given that the 'direct_access' method has been removed from 'block_device_operations', we can also go ahead and remove the block-related dax helper functions from fs/block_dev.c to drivers/dax/super.c. This keeps dax details out of the block layer and lets the DAX core be built as a module in the FS_DAX=n case. Filesystems need to include dax.h to call bdev_dax_supported().

The GITS_IIDR revision field is used to encode the migration ABI revision. So we need to restore it to check the table layout is readable by the destination.

KVM: arm64: vgic-its: Introduce migration ABI infrastructure
We plan to support different migration ABIs, ie. characterizing the ITS table layout format in guest RAM. For example, a new ABI will be needed if vLPIs get supported for nested use case. So let's introduce an array of supported ABIs (at the moment a single ABI is supported though). The following characteristics are foreseen to vary with the ABI: size of table entries, save/restore operation, the way abi settings are applied. By default the MAX_ABI_REV is applied on its creation. In subsequent patches we will introduce a way for the userspace to change the ABI in use. The entry sizes now are set according to the ABI version and not hardcoded anymore. Signed-off-by: Eric Auger <eric.auger@redhat.com> Reviewed-by: Christoffer Dall <cdall@linaro.org> |

libnvdimm for 4.12
* Region media error reporting: A libnvdimm region device is the parent to one or more namespaces. To date, media errors have been reported via the "badblocks" attribute attached to pmem block devices for namespaces in "raw" or "memory" mode. Given that namespaces can be in "device-dax" or "btt-sector" mode this new interface reports media errors generically, i.e. independent of namespace modes or state. This subsequently allows userspace tooling to craft "ACPI 6.1 Section 9.20.7.6 Function Index 4 - Clear Uncorrectable Error" requests and submit them via the ioctl path for NVDIMM root bus devices. * Introduce 'struct dax_device' and 'struct dax_operations': Prompted by a request from Linus and feedback from Christoph this allows for dax capable drivers to publish their own custom dax operations. This fixes the broken assumption that all dax operations are related to a persistent memory device, and makes it easier for other architectures and platforms to add customized persistent memory support. * 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is available for storage appliance applications to manually trigger memory controllers to drain write-pending buffers that would otherwise be flushed automatically by the platform ADR (asynchronous-DRAM-refresh) mechanism at a power loss event. Support for "locked" DIMMs is included to prevent namespaces from surfacing when the namespace label data area is locked. Finally, fixes for various reported deadlocks and crashes, also tagged for -stable. * ACPI / nfit driver updates: General updates of the nfit driver to add DSM command overrides, ACPI 6.1 health state flags support, DSM payload debug available by default, and various fixes.

ACPI / sleep: Ignore spurious SCI wakeups from suspend-to-idle
The ACPI SCI (System Control Interrupt) is set up as a wakeup IRQ during suspend-to-idle transitions and, consequently, any events signaled through it wake up the system from that state. However, on some systems some of the events signaled via the ACPI SCI while suspended to idle should not cause the system to wake up. In fact, quite often they should just be discarded. Arguably, systems should not resume entirely on such events, but in order to decide which events really should cause the system to resume and which are spurious, it is necessary to resume up to the point when ACPI SCIs are actually handled and processed, which is after executing dpm_resume_noirq() in the system resume path. For this reasons, add a loop around freeze_enter() in which the platforms can process events signaled via multiplexed IRQ lines like the ACPI SCI and add suspend-to-idle hooks that can be used for this purpose to struct platform_freeze_ops. In the ACPI case, the ->wake hook is used for checking if the SCI has triggered while suspended and deferring the interrupt-induced system wakeup until the events signaled through it are actually processed sufficiently to decide whether or not the system should resume. In turn, the ->sync hook allows all of the relevant event queues to be flushed so as to prevent events from being missed due to race conditions. In addition to that, some ACPI code processing wakeup events needs to be modified to use the "hard" version of wakeup triggers, so that it will cause a system resume to happen on device-induced wakeup events even if the "soft" mechanism to prevent the system from suspending is not enabled (that also helps to catch device-induced wakeup events occurring during suspend transitions in progress).

PM / wakeup: Integrate mechanism to abort transitions in progress
The system wakeup framework is not very consistent with respect to the way it handles suspend-to-idle and generally wakeup events occurring during transitions to system low-power states. First off, system transitions in progress are aborted by the event reporting helpers like pm_wakeup_event() only if the wakeup_count sysfs attribute is in use (as documented), but there are cases in which system-wide transitions should be aborted even if that is not the case. For example, a wakeup signal from a designated wakeup device during system-wide PM transition, it should cause the transition to be aborted right away. Moreover, there is a freeze_wake() call in wakeup_source_activate(), but that really is only effective after suspend_freeze_state has been set to FREEZE_STATE_ENTER by freeze_enter(). However, it is very unlikely that wakeup_source_activate() will ever be called at that time, as it could only be triggered by a IRQF_NO_SUSPEND interrupt handler, so wakeups from suspend-to-idle don't really occur in wakeup_source_activate(). At the same time there is a way to abort a system suspend in progress (or wake up the system from suspend-to-idle), which is by calling pm_system_wakeup(), but in turn that doesn't cause any wakeup source objects to be activated, so it will not be covered by wakeup source statistics and will not prevent the system from suspending again immediately (in case autosleep is used, for example). Consequently, if anyone wants to abort system transitions in progress and allow the wakeup_count mechanism to work, they need to use both pm_system_wakeup() and pm_wakeup_event(), say, at the same time which is awkward. For the above reasons, make it possible to trigger pm_system_wakeup() from within wakeup_source_activate() and provide a new pm_wakeup_hard_event() helper to do so within the wakeup framework.

powerpc updates for 4.12 part 1.
Highlights include:
- Larger virtual address space on 64-bit server CPUs. By default we use a 128TB
virtual address space, but a process can request access to the full 512TB by
passing a hint to mmap().
- Support for the new Power9 "XIVE" interrupt controller.
- TLB flushing optimisations for the radix MMU on Power9.
- Support for CAPI cards on Power9, using the "Coherent Accelerator Interface
Architecture 2.0".
- The ability to configure the mmap randomisation limits at build and runtime.
- Several small fixes and cleanups to the kprobes code, as well as support for
KPROBES_ON_FTRACE.
- Major improvements to handling of system reset interrupts, correctly treating
them as NMIs, giving them a dedicated stack and using a new hypervisor call
to trigger them, all of which should aid debugging and robustness.
Many fixes and other minor enhancements.

tcp: randomize timestamps on syncookies
Whole point of randomization was to hide server uptime, but an attacker
can simply start a syn flood and TCP generates 'old style' timestamps,
directly revealing server jiffies value.
Also, TSval sent by the server to a particular remote address vary
depending on syncookies being sent or not, potentially triggering PAWS
drops for innocent clients.
Lets implement proper randomization, including for SYNcookies.
Also we do not need to export sysctl_tcp_timestamps, since it is not
used from a module.
In v2, I added Florian feedback and contribution, adding tsoff to
tcp_get_cookie_sock().
v3 removed one unused variable in tcp_v4_connect() as Florian spotted.

trace: thermal: add another parameter 'power' to the tracing function
This patch adds another parameter to the trace function: trace_thermal_power_devfreq_get_power(). In case when we call directly driver's code for the real power, we do not have static/dynamic_power values. Instead we get total power in the '*power' value. The 'static_power' and 'dynamic_power' are set to 0. Therefore, we have to trace that '*power' value in this scenario.

thermal: devfreq_cooling: add new interface for direct power read
This patch introduces a new interface for device drivers connected to
devfreq_cooling in the thermal framework: get_real_power().
Some devices have more sophisticated methods (like power counters)
to approximate the actual power that they use.
In the previous implementation we had a pre-calculated power
table which was then scaled by 'utilization'
('busy_time' and 'total_time' taken from devfreq 'last_status').
With this new interface the driver can provide more precise data
regarding actual power to the thermal governor every time the power
budget is calculated. We then use this value and calculate the real
resource utilization scaling factor.

char/misc patches for 4.12-rc1
Here is the big set of new char/misc driver drivers and features for 4.12-rc1. There's lots of new drivers added this time around, new firmware drivers from Google, more auxdisplay drivers, extcon drivers, fpga drivers, and a bunch of other driver updates. Nothing major, except if you happen to have the hardware for these drivers, and then you will be happy :) All of these have been in linux-next for a while with no reported issues.

drm/tegra: Changes for v4.12-rc1
This contains various fixes to the host1x driver as well as a plug for a leak of kernel pointers to userspace. A fairly big addition this time around is the Video Image Composer (VIC) support that can be used to accelerate some 2D and image compositing operations. Furthermore the driver now supports FB modifiers, so we no longer rely on a custom IOCTL to set those. Finally this contains a few preparatory patches for Tegra186 support which unfortunately didn't quite make it this time, but will hopefully be ready for v4.13. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEiOrDCAFJzPfAjcif3SOs138+s6EFAljmxI8THHRyZWRpbmdA bnZpZGlhLmNvbQAKCRDdI6zXfz6zocZaD/9AaoXn19oEPYiWx+MjIAkhBiYEw+oq RrJ1uVisZIx8Y+ftVtwURLh3HS7SXg3F3mjJxfJVxqqlGfTCry0eiru1qbAbkwC2 ebStjdBBnAhMws22Dba5R5aHh21b1px/fj9u+jtiqcKgWzB28D+jH6G4ViTzOgXs TT1inq5SQfpL3e0+ovmVEh7/URdWf5tPQVWVuvOewTdVA2NYRXpAAFKhGWp4vD28 brvGPzYgEzBF1Q8p3f9kczbtwqChZuwnwVeP/9EP+U+gApIlmFC8XTISAuBYHWfT baJQJ/V5wjM8m3FmsX4YL8VKplhw2/JMINfD37hzjVlqskN5V80KfNlKTe8yAK96 sP0HDg72zlZ0HHOmOESuxyNyLRYkDpuVNKh4my24u77y/VcpihwMRPc8chnpG76h jh+7qlZZM8XNnVnFJN5HWLiRTUjZ9y3loJ//Wu97JkOr7SuHQ7qzhPDZV/jZepIG XkSD1dac7ii2huA6zxSFZzylwBvLHyrdj4s7imNckkNSbVNpm204Bzs0Rr2ju0bv YBe2+yGkurE8ePfONeaAkpFxHkAkdC0b2SlbZf7MgSaant2s/CV9DGgj03ZipC1g n2juRlDGLw+B1MOU+dWv/cMZmrO3Xg36E0gYgqskYRunqTdVT+Vx70D0rygo7hDd G7qvllT6oqKJ1g== =Eqtp -----END PGP SIGNATURE----- Merge tag 'drm/tegra/for-4.12-rc1' of git://anongit.freedesktop.org/tegra/linux into drm-next drm/tegra: Changes for v4.12-rc1 This contains various fixes to the host1x driver as well as a plug for a leak of kernel pointers to userspace.

Driver core patches for 4.12-rc1
Very tiny pull request for 4.12-rc1 for the driver core this time around. There are some documentation fixes, an eventpoll.h fixup to make it easier for the libc developers to take our header files directly, and some very minor driver core fixes and changes. All have been in linux-next for a very long time with no reported issues.

USB patches for 4.12-rc1
Here is the big USB patchset for 4.12-rc1. Lots of good stuff here, after many many many attempts, the kernel finally has a working typeC interface, many thanks to the Heikki and Guenter and others who have taken the time to get this merged. It wasn't an easy path for them at all. There's also a staging driver that uses this new api, which is why it's coming in through this tree. Along with that, there's the usual huge number of changes for gadget drivers, xhci, and other stuff. Johan also finally refactored pretty much every driver that was looking at USB endpoints to do it in a common way, which will help prevent any "badly-formed" devices from causing problems in drivers. That too wasn't a simple task. All of these have been in linux-next for a while with no reported issues.
