Enric Balletbo i Serra	ecf8a6cd94	mfd / platform: cros_ec: Move lightbar attributes to its own driver ... The entire way how cros sysfs attibutes are created is broken. cros_ec_lightbar should be its own driver and its attributes should be associated with a lightbar driver not the mfd driver. In order to retain the path, the lightbar attributes are attached to the cros_class. The patch also adds the sysfs documentation.

Minchan Kim	1d69a3f8ae	zram: idle writeback fixes and cleanup ... This patch includes some fixes and cleanup for idle-page writeback. 1. writeback_limit interface Now writeback_limit interface is rather conusing. For example, once writeback limit budget is exausted, admin can see 0 from /sys/block/zramX/writeback_limit which is same semantic with disable writeback_limit at this moment. IOW, admin cannot tell that zero came from disable writeback limit or exausted writeback limit. To make the interface clear, let's sepatate enable of writeback limit to another knob - /sys/block/zram0/writeback_limit_enable * before: while true : # to re-enable writeback limit once previous one is used up echo 0 > /sys/block/zram0/writeback_limit echo $((200<<20)) > /sys/block/zram0/writeback_limit .. .. # used up the writeback limit budget * new # To enable writeback limit, from the beginning, admin should # enable it. echo $((200<<20)) > /sys/block/zram0/writeback_limit echo 1 > /sys/block/zram/0/writeback_limit_enable while true : echo $((200<<20)) > /sys/block/zram0/writeback_limit .. .. # used up the writeback limit budget It's much strightforward. 2. fix condition check idle/huge writeback mode check The mode in writeback_store is not bit opeartion any more so no need to use bit operations. Furthermore, current condition check is broken in that it does writeback every pages regardless of huge/idle. 3. clean up idle_store No need to use goto.

The dax_pmem_compat driver implements the original /sys/class/dax sysfs layout rather than /sys/bus/dax. When userspace is upgraded it can blacklist this module and switch to the dax_pmem driver going forward.

Minchan Kim	bb416d18b8	zram: writeback throttle ... If there are lots of write IO with flash device, it could have a wearout problem of storage. To overcome the problem, admin needs to design write limitation to guarantee flash health for entire product life. This patch creates a new knob "writeback_limit" for zram. writeback_limit's default value is 0 so that it doesn't limit any writeback. If admin want to measure writeback count in a certain period, he could know it via /sys/block/zram0/bd_stat's 3rd column. If admin want to limit writeback as per-day 400M, he could do it like below.

Minchan Kim	a939888ec3	zram: support idle/huge page writeback ... Add a new feature "zram idle/huge page writeback". In the zram-swap use case, zram usually has many idle/huge swap pages. It's pointless to keep them in memory (ie, zram). To solve this problem, this feature introduces idle/huge page writeback to the backing device so the goal is to save more memory space on embedded systems. Normal sequence to use idle/huge page writeback feature is as follows, while (1) { # mark allocated zram slot to idle echo all > /sys/block/zram0/idle # leave system working for several hours # Unless there is no access for some blocks on zram, # they are still IDLE marked pages. echo "idle" > /sys/block/zram0/writeback or/and echo "huge" > /sys/block/zram0/writeback # write the IDLE or/and huge marked slot into backing device # and free the memory. } Per the discussion at https://lore.kernel.org/lkml/20181122065926.GG3441@jagdpanzerIV/T/#u, This patch removes direct incommpressibe page writeback feature (d2afd25114f4 ("zram: write incompressible pages to backing device")). Below concerns from Sergey: == &< == "IDLE writeback" is superior to "incompressible writeback". "incompressible writeback" is completely unpredictable and uncontrollable; it depens on data patterns and compression algorithms. While "IDLE writeback" is predictable. I even suspect, that, *ideally*, we can remove "incompressible writeback". "IDLE pages" is a super set which also includes "incompressible" pages. So, technically, we still can do "incompressible writeback" from "IDLE writeback" path; but a much more reasonable one, based on a page idling period. I understand that you want to keep "direct incompressible writeback" around. ZRAM is especially popular on devices which do suffer from flash wearout, so I can see "incompressible writeback" path becoming a dead code, long term. == &< == Below concerns from Minchan: == &< == My concern is if we enable CONFIG_ZRAM_WRITEBACK in this implementation, both hugepage/idlepage writeck will turn on. However someuser want to enable only idlepage writeback so we need to introduce turn on/off knob for hugepage or new CONFIG_ZRAM_IDLEPAGE_WRITEBACK for those usecase. I don't want to make it complicated *if possible*. Long term, I imagine we need to make VM aware of new swap hierarchy a little bit different with as-is. For example, first high priority swap can return -EIO or -ENOCOMP, swap try to fallback to next lower priority swap device. With that, hugepage writeback will work tranparently. So we could regard it as regression because incompressible pages doesn't go to backing storage automatically. Instead, user should do it via "echo huge" > /sys/block/zram/writeback" manually. == &< == Link: http://lkml.kernel.org/r/20181127055429.251614-6-minchan@kernel.org Signed-off-by: Minchan Kim <minchan@kernel.org> Reviewed-by: Joey Pabalinas <joeypabalinas@gmail.com> Reviewed-by: Sergey Senozhatsky <sergey.senozhatsky@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>	2018-12-28 12:11:49 -08:00
Minchan Kim	e82592c4fd	zram: introduce ZRAM_IDLE flag ... To support idle page writeback with upcoming patches, this patch introduces a new ZRAM_IDLE flag. Userspace can mark zram slots as "idle" via "echo all > /sys/block/zramX/idle" which marks every allocated zram slot as ZRAM_IDLE. User could see it by /sys/kernel/debug/zram/zram0/block_state. 300 75.033841 ...i 301 63.806904 s..i 302 63.806919 ..hi Once there is IO for the slot, the mark will be disappeared. 300 75.033841 ... 301 63.806904 s..i 302 63.806919 ..hi Therefore, 300th block is idle zpage. With this feature, user can how many zram has idle pages which are waste of memory.

Mika Westerberg	dcc3c9e37f	thunderbolt: Export IOMMU based DMA protection support to userspace ... Recent systems with Thunderbolt ports may support IOMMU natively. In practice this means that Thunderbolt connected devices are placed behind an IOMMU during the whole time it is connected (including during boot) making Thunderbolt security levels redundant. This is called Kernel DMA protection [1] by Microsoft. Some of these systems still have Thunderbolt security level set to "user" in order to support OS downgrade (the older version of the OS might not support IOMMU based DMA protection so connecting a device still relies on user approval). Export this information to userspace by introducing a new sysfs attribute (iommu_dma_protection). Based on it userspace tools can make more accurate decision whether or not authorize the connected device. In addition update Thunderbolt documentation regarding IOMMU based DMA protection.

Heikki Krogerus	59abd83672	drivers: base: Introducing software nodes to the firmware node framework ... Software node is a new struct fwnode_handle type that can be used to describe devices in kernel (software). It is meant to complement fwnodes representing real firmware nodes when they are incomplete (for example missing device properties) and to supply the primary fwnode when the firmware lacks hardware description for a device completely. The software node type is really meant to replace the currently used "property_set" struct fwnode_handle type. The handling of struct property_set is glued to the generic device property handling code, and it is not possible to create a struct property_set independently from the device that it is bind to. struct property_set is only created when device properties are added to already initialized struct device, and control of it is only possible from the generic property handling code. Software nodes are instead designed to be created independently from the device entries (struct device). It makes them much more flexible, as then the device meant to be bind to the node can be created at a later time, and from another location. It is also possible to bind multiple devices to a single software node if needed. The software node implementation also includes support for node hierarchy, which was the main motivation for this commit. The node hierarchy was something that was requested for the struct property_set, but it did not seem reasonable to try to extend the property_set support for that purpose. struct property_set was really meant only for device property handling like the name suggests. Support for struct property_set is not yet removed in this commit, but it will be in the following one.

Jon Flatley	201af55da8	usb: core: added uevent for over-current ... After commit 1cbd53c8cd ("usb: core: introduce per-port over-current counters") usb ports expose a sysfs value 'over_current_count' to user space. This value on its own is not very useful as it requires manual polling. As a solution, fire a udev event from the usb hub device that specifies the values 'OVER_CURRENT_PORT' and 'OVER_CURRENT_COUNT' that indicate the path of the usb port where the over-current event occurred and the value of 'over_current_count' in sysfs. Additionally, call sysfs_notify() so the sysfs value supports poll().

Joel Pepper	b206548be6	usb: gadget: uvc: configfs: Add bFrameIndex attributes ... - Add bFrameIndex as a UVCG_FRAME_ATTR_RO for each frame size. - Automatically assign ascending bFrameIndex to each frame in a format. Before all "bFrameindex" attributes were set to "1" with no way to configure the gadget otherwise. This resulted in the host always negotiating for bFrameIndex 1 (i.e. the first frame size of the gadget). After the negotiation the host driver will set the user or application selected frame size, while the gadget is actually set to the first frame size. Now, when the containing format is linked into the streaming header, iterate over all child frame descriptors and assign ascending indices. The automatically assigned indices can be read from the new read only bFrameIndex configfs attribute in each frame descriptor item.

Laurent Pinchart	61ff10e0ea	usb: gadget: uvc: configfs: Add bFormatIndex attributes ... The UVC format description are numbered using the descriptor's bFormatIndex field. The index is used in UVC requests, and is thus needed to handle requests in userspace. Make it dynamically discoverable by exposing it in a bFormatIndex configfs attribute of the uncompressed and mjpeg format config items. The bFormatIndex value exposed through the attribute is stored in the config item private data. However, that value is never set: the driver instead computes the bFormatIndex value when linking the stream class header in the configfs hierarchy and stores it directly in the class descriptors in a separate structure. In order to expose the value through the configfs attribute, store it in the config item private data as well. This results in a small code simplification.

Marek Marczykowski-Górecki	197ecb3802	xen/balloon: add runtime control for scrubbing ballooned out pages ... Scrubbing pages on initial balloon down can take some time, especially in nested virtualization case (nested EPT is slow). When HVM/PVH guest is started with memory= significantly lower than maxmem=, all the extra pages will be scrubbed before returning to Xen. But since most of them weren't used at all at that point, Xen needs to populate them first (from populate-on-demand pool). In nested virt case (Xen inside KVM) this slows down the guest boot by 15-30s with just 1.5GB needed to be returned to Xen. Add runtime parameter to enable/disable it, to allow initially disabling scrubbing, then enable it back during boot (for example in initramfs). Such usage relies on assumption that a) most pages ballooned out during initial boot weren't used at all, and b) even if they were, very few secrets are in the guest at that time (before any serious userspace kicks in). Convert CONFIG_XEN_SCRUB_PAGES to CONFIG_XEN_SCRUB_PAGES_DEFAULT (also enabled by default), controlling default value for the new runtime switch.

And we've added fsync_mode=nobarrier which gives an option to user where it skips issuing cache_flush commands to underlying flash storage. And there are many bug fixes related to fuzzed images, revoked atomic writes, quota ops, and minor direct IO. Enhancement: - add fsync_mode=nobarrier which bypasses cache_flush command - enhance the discarding flow which avoids user IOs and issues in LBA order - readahead some encrypted blocks during GC - enable in-memory inode checksum to verify the blocks if F2FS_CHECK_FS is set - enhance nat_bits behavior - set -o discard by default - set REQ_RAHEAD to bio in ->readpages Bug fixes: - fix a corner case to corrupt atomic_writes revoking flow - revisit i_gc_rwsem to fix race conditions - fix some dio behaviors captured by xfstests - correct handling errors given by quota-related failures - add many sanity check flows to avoid fuzz test failures - add more error number propagation to their callers - fix several corner cases to continue fault injection w/ shutdown loop -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAlt82U4ACgkQQBSofoJI UNJTLQ/+PhewnNa5tDfUgWdFnUFz3h9/NcC677l0OplOOUNxA8iSa1xamlKf/nf9 sB5ey0I7oBF8zQGxfndhHQfi6fpfUcNMr14hm+TS/3+d54xLJmiVShD5fjNSV2vB Ur0xoozuQDwYF1e3QKdBQjFqaCf78VheTr3aWxyv22/Sg+PYylZJ2K8rHTB7mGPU UG0aRnKrP3FPRjL7Q3m0Vm6b6eZ5uNdNrFfjgn/8yuQQ9V197K8vwSbPAsR5/pOh miCQXyM708NgEYJRWkWmC/rDSQdU0/h/mGnJWrBrbceW62QefGOgd2jcVfmthHJa ZXpj+BEG5bYpCCxGxF6N+u0e28OKonCwO/uvL8YAd5icN7yXtsKzoF1CCuXxOYf1 9K5SMylCTSyrs/+LV8CJoT2ya8w0l0w+R/txUYn8UT+4AgqU+chS2kJeXqw9tcHB WLFs/rnAyofWCI/8frVBmJY+zA1ZZvTqs/lmVYrtJUkiOcMTq34WICBUAEFKV452 BM5dcu21bSIkapYispEt4Rr7o4P4HHMQ+N1i2yUZMFCz5T0RyzdybeS5THk2yVzd L0kxfYU+zHigNX51ez8+Z7DyDLDBp6jkD0e66x73bUK9TGPH+ZbnAL6gwLikmD3M +VxYl5nyW/3bxx1HdfK1Xwd4/wYMNBmdtn5NC50oZ+jpB0h8YCE= =zgbL -----END PGP SIGNATURE----- Merge tag 'f2fs-for-4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "In this round, we've tuned f2fs to improve general performance by serializing block allocation and enhancing discard flows like fstrim which avoids user IO contention.

Here is the bit set of char/misc drivers for 4.19-rc1 There is a lot here, much more than normal, seems like everyone is writing new driver subsystems these days... Anyway, major things here are: - new FSI driver subsystem, yet-another-powerpc low-level hardware bus - gnss, finally an in-kernel GPS subsystem to try to tame all of the crazy out-of-tree drivers that have been floating around for years, combined with some really hacky userspace implementations. This is only for GNSS receivers, but you have to start somewhere, and this is great to see. Other than that, there are new slimbus drivers, new coresight drivers, new fpga drivers, and loads of DT bindings for all of these and existing drivers. Full details of everything is in the shortlog.

Linus Torvalds	2475c515d4	Staging/IIO patches for 4.19-rc1 ... Here are the big staging/iio patches for 4.19-rc1. Lots of churn here, with tons of cleanups happening in staging drivers, a removal of an old crypto driver that no one was using (skein), and the addition of some new IIO drivers. Also added was a "gasket" driver from Google that needs loads of work and the erofs filesystem. Even with adding all of the new drivers and a new filesystem, we are only adding about 1000 lines overall to the kernel linecount, which shows just how much cleanup happened, and how big the unused crypto driver was. All of these have been in the linux-next tree for a while now with no reported issues. Note, you will have a merge problem with a device tree IIO file and the MAINTAINERS file, both resolutions are easy, just take all changed. There will be a skein file merge issue as well, but that file got deleted so just drop that.

Several are user-visible changes, but bring us in to line with x86 behaviour and/or fix outright bugs. Thanks to Florian Weimer for reporting many of these. - A series to improve the hvc driver & related OPAL console code, which have been seen to cause hardlockups at times. The hvc driver changes in particular have been in linux-next for ~month. - Increase our MAX_PHYSMEM_BITS to 128TB when SPARSEMEM_VMEMMAP=y. - Remove Power8 DD1 and Power9 DD1 support, neither chip should be in use anywhere other than as a paper weight. - An optimised memcmp implementation using Power7-or-later VMX instructions - Support for barrier_nospec on some NXP CPUs. - Support for flushing the count cache on context switch on some IBM CPUs (controlled by firmware), as a Spectre v2 mitigation. - A series to enhance the information we print on unhandled signals to bring it into line with other arches, including showing the offending VMA and dumping the instructions around the fault.

Linus Torvalds	3860cae64c	regulator: Changes for v4.19 ... The biggest set of changes in here is the addition of the Qualcomm RPMH driver. As well as the regualtor driver itself being quite large due to the usual involved Qualcomm regulator stuff there's also some code shared with the arm-soc tree, a bus driver required to communicate with the hardware that actually winds up being much larger than the regulator driver itself and a LLCC driver that was part of the same signed tag used with the arm-soc tree. Other than that it's a fairly standard and quiet release, highlights include: - Addition of device links from regulator consumers to their regulators, helping the core avoid dependency issues during suspend. - Support for the entertainingly innovative suspend implementation in the BD9571MWV. - Support for switch regulators on the PFUZE100, this required two goes due to backwards compatibility issues with old DTs that were discovered. - Support for Freescale PFUZE3001 and SocioNext UniPhier. - The aforementioned Qualcomm RPMH driver together with the driver changes required to support it. -----BEGIN PGP SIGNATURE----- iQFHBAABCgAxFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAltxi/ATHGJyb29uaWVA a2VybmVsLm9yZwAKCRAk1otyXVSH0GNxB/99LLeB+gfD4ckoU07Az/k77+CfIZ8D HEUA9ryP4y6isUxpZMGcZhKa48ag9RxTuAGK+gGWtKUHxPIH6o0CuRLbGm3GOo99 MTbbMaJRJIHkwsh8XjX2Adr02XSzU/9r2T3rpZD10T/J1Qj1D3W1YuvaE/fQuOII XW8QWhRuTWbVI/gSIEj+o2PcVK77yb9Nr+llNvS+BOlFAlnNo1tx3qCJ1bUiVEyD DhLkL0n0XfaOpbtZV5DIsVDiMsB+/TnXtqiijfvq0qi5SHh6jECpQYNWHBNyIkwj 4N9NQ9xfC6bArAl9tWxXvJrVXUqFSRagHeB2xLD6piWcZ0DC4K0QfEW2 =WiXl -----END PGP SIGNATURE----- Merge tag 'regulator-v4.19' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator Pull regulator updates from Mark Brown: "The biggest set of changes in here is the addition of the Qualcomm RPMH driver.

Introduce the 'l1tf=' kernel command line option to allow for boot-time switching of mitigation that is used on processors affected by L1TF. The possible values are: full Provides all available mitigations for the L1TF vulnerability. Disables SMT and enables all mitigations in the hypervisors. SMT control via /sys/devices/system/cpu/smt/control is still possible after boot. Hypervisors will issue a warning when the first VM is started in a potentially insecure configuration, i.e. SMT enabled or L1D flush disabled. full,force Same as 'full', but disables SMT control. Implies the 'nosmt=force' command line option. sysfs control of SMT and the hypervisor flush control is disabled. flush Leaves SMT enabled and enables the conditional hypervisor mitigation. Hypervisors will issue a warning when the first VM is started in a potentially insecure configuration, i.e. SMT enabled or L1D flush disabled. flush,nosmt Disables SMT and enables the conditional hypervisor mitigation. SMT control via /sys/devices/system/cpu/smt/control is still possible after boot. If SMT is reenabled or flushing disabled at runtime hypervisors will issue a warning. flush,nowarn Same as 'flush', but hypervisors will not warn when a VM is started in a potentially insecure configuration. off Disables hypervisor mitigations and doesn't emit any warnings. Default is 'flush'. Let KVM adhere to these semantics, which means: - 'lt1f=full,force' : Performe L1D flushes. No runtime control possible. - 'l1tf=full' - 'l1tf-flush' - 'l1tf=flush,nosmt' : Perform L1D flushes and warn on VM start if SMT has been runtime enabled or L1D flushing has been run-time enabled - 'l1tf=flush,nowarn' : Perform L1D flushes and no warnings are emitted. - 'l1tf=off' : L1D flushes are not performed and no warnings are emitted. KVM can always override the L1D flushing behavior using its 'vmentry_l1d_flush' module parameter except when lt1f=full,force is set. This makes KVM's private 'nosmt' option redundant, and as it is a bit non-systematic anyway (this is something to control globally, not on hypervisor level), remove that option.

Thomas Gleixner	05736e4ac1	cpu/hotplug: Provide knobs to control SMT ... Provide a command line and a sysfs knob to control SMT. The command line options are: 'nosmt': Enumerate secondary threads, but do not online them 'nosmt=force': Ignore secondary threads completely during enumeration via MP table and ACPI/MADT. The sysfs control file has the following states (read/write): 'on': SMT is enabled. Secondary threads can be freely onlined 'off': SMT is disabled. Secondary threads, even if enumerated cannot be onlined 'forceoff': SMT is permanentely disabled. Writes to the control file are rejected. 'notsupported': SMT is not supported by the CPU The command line option 'nosmt' sets the sysfs control to 'off'. This can be changed to 'on' to reenable SMT during runtime. The command line option 'nosmt=force' sets the sysfs control to 'forceoff'. This cannot be changed during runtime. When SMT is 'on' and the control file is changed to 'off' then all online secondary threads are offlined and attempts to online a secondary thread later on are rejected. When SMT is 'off' and the control file is changed to 'on' then secondary threads can be onlined again. The 'off' -> 'on' transition does not automatically online the secondary threads. When the control file is set to 'forceoff', the behaviour is the same as setting it to 'off', but the operation is irreversible and later writes to the control file are rejected. When the control status is 'notsupported' then writes to the control file are rejected.

Eugen Hristev	3055a6cfa0	iio: Add channel for Position Relative ... Add new channel type for relative position on a pad. These type of analog sensor offers the position of a pen on a touchpad, and is represented as a voltage, which can be converted to a position on X and Y axis on the pad. The channel will hand the relative position on the pad in both directions. The channel can then be consumed by a touchscreen driver or read as-is for a raw indication of the touchpen on a touchpad.

Linus Torvalds	eafdca4d70	Staging/IIO patches for 4.18-rc1 ... Here is the big staging and IIO driver update for 4.18-rc1. It was delayed as I wanted to make sure the final driver deletions did not cause any major merge issues, and all now looks good. There are a lot of patches here, just over 1000. The diffstat summary shows the major changes here: 1007 files changed, 16828 insertions(+), 227770 deletions(-) Because of this, we might be close to shrinking the overall kernel source code size for two releases in a row. There was loads of work in this release cycle, primarily: - tons of ks7010 driver cleanups - lots of mt7621 driver fixes and cleanups - most driver cleanups - wilc1000 fixes and cleanups - lots and lots of IIO driver cleanups and new additions - debugfs cleanups for all staging drivers - lots of other staging driver cleanups and fixes, the shortlog has the full details. but the big user-visable things here are the removal of 3 chunks of code: - ncpfs and ipx were removed on schedule, no one has cared about this code since it moved to staging last year, and if it needs to come back, it can be reverted. - lustre file system is removed. I've ranted at the lustre developers about once a year for the past 5 years, with no real forward progress at all to clean things up and get the code into the "real" part of the kernel. Given that the lustre developers continue to work on an external tree and try to port those changes to the in-kernel tree every once in a while, this whole thing really really is not working out at all. So I'm deleting it so that the developers can spend the time working in their out-of-tree location and get things cleaned up properly to get merged into the tree correctly at a later date. Because of these file removals, you will have merge issues on some of these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the atomisp driver). Just delete those files, it's a simple merge :) All of this has been in linux-next for a while with no reported problems.

The truncate path assumed that it is safe to disconnect a pinned page from a file and let the filesystem reclaim the physical block. With DAX the page is equivalent to the filesystem block.

Without this wait a filesystem could allocate blocks under active device-DMA to a new file. * DAX arranges for the block layer to be bypassed and uses dax_direct_access() + copy_to_iter() to satisfy read(2) calls.

For example, poison may be tracked at 64-byte alignment even though the ECC unit is larger. Unless / until the ACPI specification provides a non-ambiguous way to communicate this property do not expose this to userspace.

Vaibhav Jain	b6c84ba22f	cxl: Disable prefault_mode in Radix mode ... Currently we see a kernel-oops reported on Power-9 while attaching a context to an AFU, with radix-mode and sysfs attr 'prefault_mode' set to anything other than 'none'.

However on Power-9 with radix mode we don't have Storage-Segments that we can prefault. Also prefaulting process Pages will be too costly and fine-grained. Hence, since the prefaulting mechanism doesn't makes sense of radix-mode, this patch updates prefault_mode_store() to not allow any other value apart from CXL_PREFAULT_NONE when radix mode is enabled.

Nicolas Boichat	2524422715	usb: hub: Per-port setting to use old enumeration scheme ... The "old" enumeration scheme is considerably faster (it takes ~244ms instead of ~356ms to get the descriptor). It is currently only possible to use the old scheme globally (/sys/module/usbcore/parameters/old_scheme_first), which is not desirable as the new scheme was introduced to increase compatibility with more devices. However, in our case, we care about time-to-active for a specific USB device (which we make the firmware for), on a specific port (that is pogo-pin based: not a standard USB port). This new sysfs option makes it possible to use the old scheme on a single port only.

Matthew Garrett	fa516b66a1	EVM: Allow runtime modification of the set of verified xattrs ... Sites may wish to provide additional metadata alongside files in order to make more fine-grained security decisions[1]. The security of this is enhanced if this metadata is protected, something that EVM makes possible. However, the kernel cannot know about the set of extended attributes that local admins may wish to protect, and hardcoding this policy in the kernel makes it difficult to change over time and less convenient for distributions to enable. This patch adds a new /sys/kernel/security/integrity/evm/evm_xattrs node, which can be read to obtain the current set of EVM-protected extended attributes or written to in order to add new entries. Extending this list will not change the validity of any existing signatures provided that the file in question does not have any of the additional extended attributes - missing xattrs are skipped when calculating the EVM hash. [1] For instance, a package manager could install information about the package uploader in an additional extended attribute. Local LSM policy could then be associated with that extended attribute in order to restrict the privileges available to packages from less trusted uploaders.

Hence this better reflects reality. Also move the calibscale_available. - Avoid returning an error in the IRQ handler. - Hard code the reg value in _clear_interrupts as it only takes one value in the code. Result is the function has little purpose so opencode the two remaining i2c_smbus_write_byte calls. - Drop some unnecessary checking of the chip status register. - Tidy up return path in _write_interrupt_config. - Tidy up the ID verification code. - Move the power and diode settings defines into the header as these are needed for platform data configuration. - Various renames and comment cleanups for consistency and clarity. - Use actual device defaults for default startup settings. - SPDX - Add some range sanity checking to sysfs attribute writes. - Don't provide event interfaces if the interrupt line isn't available. - Use IIO_CONST_ATTR macro for calibscale_available as it's a constant string. - Fix the integration time and lux equations. - Make device IDs explicit index values in the device_channel_config array. -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEEbilms4eEBlKRJoGxVIU0mcT0FogFAlr0uigRHGppYzIzQGtl cm5lbC5vcmcACgkQVIU0mcT0FoiRhw//bIv57xenV6WV3+7Xmrp/rG4OBVzt8riD d9HczYKZE8/tqfB9cjF5e/xOpfin99eXBqEMWecidh3BxMNKXgnbvvCYCXF+m47D 3cYlWvGbyZ2lbvqwbYCkk4xKfPNbRHBo5NX9TB08wf7DrAjmaudxmxDSFrRYQCho 3Z3H2o54z1i/iJud61TApEONxr7H5oFdeb6uwNB5UVlG7XING9mfWbmlSzdlxW4X lHG4hC1/Pz/F4WjiLvNKccjhuq1f60CwSppKvfihq1IZKYKyHvSWjOicwrNb3QB2 Kr0dT8yDqNKcKU1tsfgfR+YFeLKq52Ik4whulk8mkL7E4IWVIkGbL0ewkPwZ0YqO Cj9Nv52vzYS7x9Dj7R6f23Lwq30a19WKXixybjdo9zV14S0XKfzTmU7xC/4yhEjh yUg9QPjWxE5rAUTSjNF0C6tv786Y3aVYBp2jscIroSutipa6cUyc2rOKssM6GTZs vyRElGiUEXbg7uI7GrwN4PJszho47ptkFGn/o88Sy90KjUJ0mP15NTlp4IeSiVc/ sM4YHHQ7tldcKqsaKeGbH8JwJNvzj9Kh20zniYd9lSZkeZusSkZUvd1FgB5uUocb ZZEG2IzCLM/utH49yXyaUkRS/lqoGCcObDkIHbsE1OM8q2bnZxaUYEMumxIpAs7l W2LBlr3vGF4= =egCX -----END PGP SIGNATURE----- Merge tag 'iio-for-4.18a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: 1st round of IIO new device support, features and cleanup for the 4.18 cycle A nice mix this time of excellent cleanups (many to send drivers speeding toward staging graduations) and new drivers / device support.

Reorganize the definitions to group register address and fields. - Use sign_extend32 rather than open coding. - Reverse Xmas tree ordering where appropriate and align function args. - Remove unused headers. - Use GENMASK where appropriate instead of open coding. * adis16209 (staging) - Indent field definitions to visually separate them from register address definitions. - Use reverse xmas tree ordering where appropriate. - Add some whitespace where it will help readability. - Drop some unused headers. - Use GENMASK where appropriate. * ad2s1200 - Drop unnecessary includes and reorder alphabetically. - Reverse xmas tree and blank line cleanups. * atlas-ph-sensor - Use msleep instead of usleep_range where the precise value doesn't matter and the delays are long. * bcm150 - Drop transaction splitting as core now handles it. * cros_ec - Move the shared header to the include/iio/common directory. This brings it inline with the other multiple type devices. - Use drvdata directly from device rather than boucing via the platform_device structure. * hid-sensors - Use drvdata directly from device rather than boucing via the platform_device structure. * inv_mpu6050 - Clear out a second function definition for the same function. - Don't flush fifo when the iio buffer is full but just drop excess data. - Tidy up set_power_itg and ensure it is used in the right places. - Use set_power_itg rather than opencoding it again in the i2c mux control. - Make sure error paths disable the power if undoing power on. - Used managed devm_ functions during probe. Delete remove function. - Refactor to pull raw data read out of read_raw function. - Simplify data reading error paths. - Only enable the i2c mux for chips with the i2c aux bus (not icm20608) - Fix a potential deadlock due to varying lock ordering. - Fix an issue where first sample from gyro after enabling is unstable by dropping the first sample. - Fix an issue where the user_ctrl register is incorrectly overwritten. - Tidy up some grammar and spelling minor issus. * mcp320x - Use vendor compatible strings. * mcp4018 - Switch to using i2c .probe_new. * mcp4351 - switch to using i2c .probe_new. * meson-adc - rework handing on common ADC platform data so it can be shared across multiple families of SoCs. * sca3000 - Fix an error handling path if the ring configure fails. * st_lsm6dsx - Fix a wrong fifo threshold mask (no actual effect) * stm32-dfsdm - Style fixes and cleanups. - Check filter ID is in range and check spi-max-frequency. * tsl2x7x (staging) - Drop some unnecessary function calls, unused variables and unnecessary local variables. - Fix wrong interrupt type. - Avoid unnecessary double clear of interrupt. - Simplify proximity calibration call which did various things unrelated to actually calibrating. - Separate control of the proximity and ALS interrupts. - Improve consistency of logging. - Separate ALS and proximity persistence settings as they have separate hardware controls. - Tidy up variable ordering. - Add Brian to copyright notice given consider work on this driver. - Take advantage of hardware support for I2C address auto increment. - Combine individuaal enable and period attributes for the two directions on the threshold events into a single value as the hardware doesn't separate them. - Move integration_time* attributes from light channel to intensity value as they effect the intensity readings directly and the light reading only indirectly. Hence this better reflects reality. Also move the calibscale_available. - Avoid returning an error in the IRQ handler. - Hard code the reg value in _clear_interrupts as it only takes one value in the code. Result is the function has little purpose so opencode the two remaining i2c_smbus_write_byte calls. - Drop some unnecessary checking of the chip status register. - Tidy up return path in _write_interrupt_config. - Tidy up the ID verification code. - Move the power and diode settings defines into the header as these are needed for platform data configuration. - Various renames and comment cleanups for consistency and clarity. - Use actual device defaults for default startup settings. - SPDX - Add some range sanity checking to sysfs attribute writes. - Don't provide event interfaces if the interrupt line isn't available. - Use IIO_CONST_ATTR macro for calibscale_available as it's a constant string. - Fix the integration time and lux equations. - Make device IDs explicit index values in the device_channel_config array.	2018-05-11 09:50:04 +02:00

This patch adds "driver_override" device attribute for rpmsg_device which will allow users to explicitly specify the rpmsg_driver to be used via sysfs entry. The "driver_override" device attribute implemented here is very similar to "driver_override" implemented for platform, pci, and amba bus types.

Adam Thomson	cf45004195	power: supply: Add 'usb_type' property and supporting code ... This commit adds the 'usb_type' property to represent USB supplies which can report a number of different types based on a connection event. Examples of this already exist in drivers whereby the existing 'type' property is updated, based on an event, to represent what was connected (e.g. USB, USB_DCP, USB_ACA, ...). Current implementations however don't show all supported connectable types, so this knowledge has to be exlicitly known for each driver that supports this. The 'usb_type' property is intended to fill this void and show users all possible USB types supported by a driver. The property, when read, shows all available types for the driver, and the one currently chosen is highlighted/bracketed. It is expected that the 'type' property would then just show the top-level type 'USB', and this would be static. Currently the 'usb_type' enum contains all of the USB variant types that exist for the 'type' enum at this time, and in addition has SDP and PPS types. The mirroring is intentional so as to not impact existing usage of the 'type' property.

Matthew Garrett	d906c10d8a	IMA: Support using new creds in appraisal policy ... The existing BPRM_CHECK functionality in IMA validates against the credentials of the existing process, not any new credentials that the child process may transition to. Add an additional CREDS_CHECK target and refactor IMA to pass the appropriate creds structure. In ima_bprm_check(), check with both the existing process credentials and the credentials that will be committed when the new process is started. This will not change behaviour unless the system policy is extended to include CREDS_CHECK targets - BPRM_CHECK will continue to check the same credentials that it did previously. After this patch, an IMA policy rule along the lines of: measure func=CREDS_CHECK subj_type=unconfined_t will trigger if a process is executed and runs as unconfined_t, ignoring the context of the parent process. This is in contrast to: measure func=BPRM_CHECK subj_type=unconfined_t which will trigger if the process that calls exec() is already executing in unconfined_t, ignoring the context that the child process executes into.

Heikki Krogerus	fde0aa6c17	usb: common: Small class for USB role switches ... USB role switch is a device that can be used to choose the data role for USB connector. With dual-role capable USB controllers, the controller itself will be the switch, but on some platforms the USB host and device controllers are separate IPs and there is a mux between them and the connector. On those platforms the mux driver will need to register the switch. With USB Type-C connectors, the host-to-device relationship is negotiated over the Configuration Channel (CC). That means the USB Type-C drivers need to be in control of the role switch. The class provides a simple API for the USB Type-C drivers for the control. For other types of USB connectors (mainly microAB) the class provides user space control via sysfs attribute file that can be used to request role swapping from the switch.

Richard Leitner	1cbd53c8cd	usb: core: introduce per-port over-current counters ... For some userspace applications information on the number of over-current conditions at specific USB hub ports is relevant. In our case we have a series of USB hardware (using the cp210x driver) which communicates using a proprietary protocol. These devices sometimes trigger an over-current situation on some hubs. In case of such an over-current situation the USB devices offer an interface for reducing the max used power. As these conditions are quite rare and imply performance reductions of the device we don't want to reduce the max power always. Therefore give user-space applications the possibility to react adequately by introducing an over_current_counter in the usb port struct which is exported via sysfs.

Adrian Hunter	ad44837882	scsi: ufs: Add support for Auto-Hibernate Idle Timer ... UFS host controllers may support an autonomous power management feature called the Auto-Hibernate Idle Timer. The timer is set to the number of microseconds of idle time before the UFS host controller will autonomously put the link into Hibernate state. That will save power at the expense of increased latency. Any access to the host controller interface registers will automatically put the link out of Hibernate state. So once configured, the feature is transparent to the driver. Expose the Auto-Hibernate Idle Timer value via SysFS to allow users to choose between power efficiency or lower latency.

Rafael J. Wysocki	95c513ec84	ACPI: Add Time and Alarm Device (TAD) driver ... Introduce a driver for the ACPI Time and Alarm Device (TAD) based on Section 9.18 of ACPI 6.2. This driver only supports the system wakeup capabilities of the TAD which are mandatory. Support for the RTC capabilities of the TAD will be added to it in the future. This driver is entirely sysfs-based. It provides attributes (under the TAD platform device) to allow user space to manage the AC and DC wakeup timers of the TAD: set and read their values, set and check their expire timer wake policies, check and clear their status and check the capabilities of the TAD reported by AML. The DC timer attributes are only present if the TAD supports a separate DC alarm timer.

Mika Westerberg	6fc14e1a44	thunderbolt: Introduce USB only (SL4) security level ... This new security level works so that it creates one PCIe tunnel to the connected Thunderbolt dock, removing PCIe links downstream of the dock. This leaves only the internal USB controller visible. Display Port tunnels are created normally. While there make sure security sysfs attribute returns "unknown" for any future security level.

Mika Westerberg	9aaa3b8b4c	thunderbolt: Add support for preboot ACL ... Preboot ACL is a mechanism that allows connecting Thunderbolt devices boot time in more secure way than the legacy Thunderbolt boot support. As with the legacy boot option, this also needs to be enabled from the BIOS before booting is allowed. Difference to the legacy mode is that the userspace software explicitly adds device UUIDs by sending a special message to the ICM firmware. Only the devices listed in the boot ACL are connected automatically during the boot. This works in both "user" and "secure" security levels. We implement this in Linux by exposing a new sysfs attribute (boot_acl) below each Thunderbolt domain. The userspace software can then update the full list as needed.

Yehezkel Bernat	14862ee308	thunderbolt: Add 'boot' attribute for devices ... In various cases, Thunderbolt device can be connected by ICM on boot without waiting for approval from user. Most cases are related to OEM-specific BIOS configurations. This information is interesting for user-space as if the device isn't in SW ACL, it may create a friction in the user experience where the device is automatically authorized if it's connected on boot but requires an explicit user action if connected after OS is up. User-space can use this information to suggest adding the device to SW ACL for auto-authorization on later connections.

Alexandre Belloni	ac75779b72	rtc: nvmem: allow registering the nvmem device before the rtc ... Switch the parent of the nvmem device to the parent of the rtc device so it can be registered before the RTC. This is a small change in the ABI as the nvmem moves out of the /sys/class/rtc/rtcX folder to be under the parent device folder (that is where the previous nvram files where registered). However, it is still available under its correct location, /sys/bus/nvmem/devices which is the one that should be used by userspace applications. The other benefit is that the nvmem device can stay registered even if the rtc registration fails. Or it is possible to not register the rtc if the nvmem registration failed. Finally, it makes a lot of sense for devices that actually have different i2c or spi addresses for the RTC and the EEPROM. That is basically how it would end up when using MFD or even completely separate devices. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>	2018-03-01 10:49:14 +01:00

The majority of the work here is in the firmware subsystem, with reworks to try to attempt to make the code easier to handle in the long run, but no functional change.

Linus Torvalds	5d8515bc23	Staging/IIO patches for 4.16-rc1 ... Here is the big Staging and IIO driver patches for 4.16-rc1. There is the normal amount of new IIO drivers added, like all releases. The networking IPX and the ncpfs filesystem are moved into the staging tree, as they are on their way out of the kernel due to lack of use anymore. The visorbus subsystem finall has started moving out of the staging tree to the "real" part of the kernel, and the most and fsl-mc codebases are almost ready to move out, that will probably happen for 4.17-rc1 if all goes well. Other than that, there is a bunch of license header cleanups in the tree, along with the normal amount of coding style churn that we all know and love for this codebase.

Linus Torvalds	3c29548f87	Merge branch 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security ... Pull integrity updates from James Morris: "This contains a mixture of bug fixes, code cleanup, and new functionality. Of note is the integrity cache locking fix, file change detection, and support for a new EVM portable and immutable signature type. The re-introduction of the integrity cache lock (iint) fixes the problem of attempting to take the i_rwsem shared a second time, when it was previously taken exclusively. Defining atomic flags resolves the original iint/i_rwsem circular locking - accessing the file data vs. modifying the file metadata. Although it fixes the O_DIRECT problem as well, a subsequent patch is needed to remove the explicit O_DIRECT prevention. For performance reasons, detecting when a file has changed and needs to be re-measured, re-appraised, and/or re-audited, was limited to after the last writer has closed, and only if the file data has changed. Detecting file change is based on i_version. For filesystems that do not support i_version, remote filesystems, or userspace filesystems, the file was measured, appraised and/or audited once and never re-evaluated. Now local filesystems, which do not support i_version or are not mounted with the i_version option, assume the file has changed and are required to re-evaluate the file. This change does not address detecting file change on remote or userspace filesystems. Unlike file data signatures, which can be included and distributed in software packages (eg. rpm, deb), the existing EVM signature, which protects the file metadata, could not be included in software packages, as it includes file system specific information (eg. i_ino, possibly the UUID). This pull request defines a new EVM portable and immutable file metadata signature format, which can be included in software packages" * 'next-integrity' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: ima/policy: fix parsing of fsuuid ima: Use i_version only when filesystem supports it integrity: remove unneeded initializations in integrity_iint_cache entries ima: log message to module appraisal error ima: pass filename to ima_rdwr_violation_check() ima: Fix line continuation format ima: support new "hash" and "dont_hash" policy actions ima: re-introduce own integrity cache lock EVM: Add support for portable signature format EVM: Allow userland to permit modification of EVM-protected metadata ima: relax requiring a file signature for new files with zero length	2018-01-31 13:07:35 -08:00

Uwe Kleine-König	bbecb07fa0	siox: new driver framework for eckelmann SIOX ... SIOX is a bus system invented at Eckelmann AG to control their building management and refrigeration systems. Traditionally the bus was implemented on custom microcontrollers, today Linux based machines are in use, too. The topology on a SIOX bus looks as follows: ,------->--DCLK-->---------------+----------------------. ^ v v ,--------. ,----------------------. ,------ | | | ,--------------. | | | |--->--DOUT-->---|->-|shift register|->-|--->---| | | | `--------------' | | | master | | device | | device | | | ,--------------. | | | |---<--DIN---<---|-<-|shift register|-<-|---<---| | | | `--------------' | | `--------' `----------------------' `------ v ^ ^ `----------DLD-------------------+----------------------' There are two control lines (DCLK and DLD) driven from the bus master to all devices in parallel and two daisy chained data lines, one for input and one for output. DCLK is the clock to shift both chains by a single bit. On an edge of DLD the devices latch both their input and output shift registers. This patch adds a framework for this bus type.

Mimi Zohar	da1b0029f5	ima: support new "hash" and "dont_hash" policy actions ... The builtin ima_appraise_tcb policy, which is specified on the boot command line, can be replaced with a custom policy, normally early in the boot process. Custom policies can be more restrictive in some ways, like requiring file signatures, but can be less restrictive in other ways, like not appraising mutable files. With a less restrictive policy in place, files in the builtin policy might not be hashed and labeled with a security.ima hash. On reboot, files which should be labeled in the ima_appraise_tcb are not labeled, possibly preventing the system from booting properly. To resolve this problem, this patch extends the existing IMA policy actions "measure", "dont_measure", "appraise", "dont_appraise", and "audit" with "hash" and "dont_hash". The new "hash" action will write the file hash as security.ima, but without requiring the file to be appraised as well. For example, the builtin ima_appraise_tcb policy includes the rule, "appraise fowner=0". Adding the "hash fowner=0" rule to a custom policy, will cause the needed file hashes to be calculated and written as security.ima xattrs.

Matthew Garrett	ae1ba1676b	EVM: Allow userland to permit modification of EVM-protected metadata ... When EVM is enabled it forbids modification of metadata protected by EVM unless there is already a valid EVM signature. If any modification is made, the kernel will then generate a new EVM HMAC. However, this does not map well on use cases which use only asymmetric EVM signatures, as in this scenario the kernel is unable to generate new signatures. This patch extends the /sys/kernel/security/evm interface to allow userland to request that modification of these xattrs be permitted. This is only permitted if no keys have already been loaded. In this configuration, modifying the metadata will invalidate the EVM appraisal on the file in question. This allows packaging systems to write out new files, set the relevant extended attributes and then move them into place. There's also some refactoring of the use of evm_initialized in order to avoid heading down codepaths that assume there's a key available.

Lu Baolu	dfba2174dc	usb: xhci: Add DbC support in xHCI driver ... xHCI compatible USB host controllers(i.e. super-speed USB3 controllers) can be implemented with the Debug Capability(DbC). It presents a debug device which is fully compliant with the USB framework and provides the equivalent of a very high performance full-duplex serial link. The debug capability operation model and registers interface are defined in 7.6.8 of the xHCI specification, revision 1.1. The DbC debug device shares a root port with the xHCI host. By default, the debug capability is disabled and the root port is assigned to xHCI. When the DbC is enabled, the root port will be assigned to the DbC debug device, and the xHCI sees nothing on this port. This implementation uses a sysfs node named <dbc> under the xHCI device to manage the enabling and disabling of the debug capability. When the debug capability is enabled, it will present a debug device through the debug port. This debug device is fully compliant with the USB3 framework, and it can be enumerated by a debug host on the other end of the USB link. As soon as the debug device is configured, a TTY serial device named /dev/ttyDBC0 will be created.

Miroslav Benes	c99a2be790	livepatch: force transition to finish ... If a task sleeps in a set of patched functions uninterruptedly, it could block the whole transition indefinitely. Thus it may be useful to clear its TIF_PATCH_PENDING to allow the process to finish. Admin can do that now by writing to force sysfs attribute in livepatch sysfs directory. TIF_PATCH_PENDING is then cleared for all tasks and the transition can finish successfully. Important note! Administrator should not use this feature without a clearance from a patch distributor. It must be checked that by doing so the consistency model guarantees are not violated. Removal (rmmod) of patch modules is permanently disabled when the feature is used. It cannot be guaranteed there is no task sleeping in such module.

Miroslav Benes	43347d56c8	livepatch: send a fake signal to all blocking tasks ... Live patching consistency model is of LEAVE_PATCHED_SET and SWITCH_THREAD. This means that all tasks in the system have to be marked one by one as safe to call a new patched function. Safe means when a task is not (sleeping) in a set of patched functions. That is, no patched function is on the task's stack. Another clearly safe place is the boundary between kernel and userspace. The patching waits for all tasks to get outside of the patched set or to cross the boundary. The transition is completed afterwards. The problem is that a task can block the transition for quite a long time, if not forever. It could sleep in a set of patched functions, for example. Luckily we can force the task to leave the set by sending it a fake signal, that is a signal with no data in signal pending structures (no handler, no sign of proper signal delivered). Suspend/freezer use this to freeze the tasks as well. The task gets TIF_SIGPENDING set and is woken up (if it has been sleeping in the kernel before) or kicked by rescheduling IPI (if it was running on other CPU). This causes the task to go to kernel/userspace boundary where the signal would be handled and the task would be marked as safe in terms of live patching. There are tasks which are not affected by this technique though. The fake signal is not sent to kthreads. They should be handled differently. They can be woken up so they leave the patched set and their TIF_PATCH_PENDING can be cleared thanks to stack checking. For the sake of completeness, if the task is in TASK_RUNNING state but not currently running on some CPU it doesn't get the IPI, but it would eventually handle the signal anyway. Second, if the task runs in the kernel (in TASK_RUNNING state) it gets the IPI, but the signal is not handled on return from the interrupt. It would be handled on return to the userspace in the future when the fake signal is sent again. Stack checking deals with these cases in a better way. If the task was sleeping in a syscall it would be woken by our fake signal, it would check if TIF_SIGPENDING is set (by calling signal_pending() predicate) and return ERESTART* or EINTR. Syscalls with ERESTART* return values are restarted in case of the fake signal (see do_signal()). EINTR is propagated back to the userspace program. This could disturb the program, but... * each process dealing with signals should react accordingly to EINTR return values. * syscalls returning EINTR happen to be quite common situation in the system even if no fake signal is sent. * freezer sends the fake signal and does not deal with EINTR anyhow. Thus EINTR values are returned when the system is resumed. The very safe marking is done in architectures' "entry" on syscall and interrupt/exception exit paths, and in a stack checking functions of livepatch. TIF_PATCH_PENDING is cleared and the next recalc_sigpending() drops TIF_SIGPENDING. In connection with this, also call klp_update_patch_state() before do_signal(), so that recalc_sigpending() in dequeue_signal() can clear TIF_PATCH_PENDING immediately and thus prevent a double call of do_signal(). Note that the fake signal is not sent to stopped/traced tasks. Such task prevents the patching to finish till it continues again (is not traced anymore). Last, sending the fake signal is not automatic. It is done only when admin requests it by writing 1 to signal sysfs attribute in livepatch sysfs directory.

Linus Torvalds	6aa2f9441f	This is the bulk of GPIO changes for the v4.15 kernel cycle: ... CORE: - Fix the semantics of raw GPIO to actually be raw. No inversion semantics as before, but also no open draining, and allow the raw operations to affect lines used for interrupts as the caller supposedly knows what they are doing if they are getting the big hammer. - Rewrote the __inner_function() notation calls to names that make more sense. I just find this kind of code disturbing. - Drop the .irq_base() field from the gpiochip since now all IRQs are mapped dynamically. This is nice. - Support for .get_multiple() in the core driver API. This allows us to read several GPIO lines with a single register read. This has high value for some usecases: it can be used to create oscilloscopes and signal analyzers and other things that rely on reading several lines at exactly the same instant. Also a generally nice optimization. This uses the new assign_bit() macro from the bitops lib that was ACKed by Andrew Morton and is implemented for two drivers, one of them being the generic MMIO driver so everyone using that will be able to benefit from this. - Do not allow requests of Open Drain and Open Source setting of a GPIO line simultaneously. If the hardware actually supports enabling both at the same time the electrical result would be disastrous. - A new interrupt chip core helper. This will be helpful to deal with "banked" GPIOs, which means GPIO controllers with several logical blocks of GPIO inside them. This is several gpiochips per device in the device model, in contrast to the case when there is a 1-to-1 relationship between a device and a gpiochip. NEW DRIVERS: - Maxim MAX3191x industrial serializer, a very interesting piece of professional I/O hardware. - Uniphier GPIO driver. This is the GPIO block from the recent Socionext (ex Fujitsu and Panasonic) platform. - Tegra 186 driver. This is based on the new banked GPIO infrastructure. OTHER IMPROVEMENTS: - Some documentation improvements. - Wakeup support for the DesignWare DWAPB GPIO controller. - Reset line support on the DesignWare DWAPB GPIO controller. - Several non-critical bug fixes and improvements for the Broadcom BRCMSTB driver. - Misc non-critical bug fixes like exotic errorpaths, removal of dead code etc. - Explicit comments on fall-through switch() statements. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJaCvGiAAoJEEEQszewGV1z+oAQAJUpdPH/msdgHDuXSuBcbuFq NObQdkRiz1hez4vJOT+kbgES6ay57MArnbmM/xRdy+37lKrmkP+yfZe4UUruQhhW f2GVlwBbUp9tIzNliS8IYWO0tj+BTYyg1MQx0C0nE1zMZqVZk44EDa9SO6esRaFJ SLc2BpO3oJCQRaObe0+KTHIJV0dK3vQh4QXSzL+cM5u7P67Jq+wv4xdLVVScwbJB 4jgwVER3Ah0E1jHclIG2PxI1rbYKwlOBumafOTUlq5fmfC3tULVPJEm9FXcdaBLJ KAmtxX4yi+SgUccYFsmK+fNNLVQiAjmkhJCl6kxVOrxYqamrG100YST4Iew3sakM /iQ3lpup5L6eJ/dndfgE207OqRFhvAzNRxORv1p/wJIRLmV1/QehCX8GYOcDumXY MySRcEeUeZPfBHcnjIDRP6y/XOg8zBKso7GL+feRgLZUJZlNQZqokdC95TY9S5nm QLK+sU367o41tomyv5TP3y1DDsym6+ZdpuOUh73znxuz2x/x+FfTfwM2J0r8Ussm GQTfAojeBI9aSOZ2mvgRI1XxSprXqO3FFFWBwrQ6RS9rBceLF1o2ySKC2gI0FG5d 6GBkARcN5RyyNtYkH923pyrqz/FZJc6ZkrsUTGmERM5HGuWwczcditqwYRhbHwl8 pIlmX4y0AYh6FFVoIcQE =8Mon -----END PGP SIGNATURE----- Merge tag 'gpio-v4.15-1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.15 kernel cycle: Core: - Fix the semantics of raw GPIO to actually be raw.

The most noticeable change is probably the relocation of the OPP (Operating Performance Points) framework to its own directory under drivers/ as it has grown big enough for that. Also Viresh is now going to maintain it and send pull requests for it to me, so you will see this change in the git history going forward (but still not right now). Another noticeable set of changes is the modifications of the PM core, the PCI subsystem and the ACPI PM domain to allow of more integration between system-wide suspend/resume and runtime PM. For now it's just a way to avoid resuming devices from runtime suspend unnecessarily during system suspend (if the driver sets a flag to indicate its readiness for that) and in the works is an analogous mechanism to allow devices to stay suspended after system resume. In addition to that, we have some changes related to supporting frequency-invariant CPU utilization metrics in the scheduler and in the schedutil cpufreq governor on ARM and changes to add support for device performance states to the generic power domains (genpd) framework.

Matthew Garrett	f00d797507	EVM: Allow userspace to signal an RSA key has been loaded ... EVM will only perform validation once a key has been loaded. This key may either be a symmetric trusted key (for HMAC validation and creation) or the public half of an asymmetric key (for digital signature validation). The /sys/kernel/security/evm interface allows userland to signal that a symmetric key has been loaded, but does not allow userland to signal that an asymmetric public key has been loaded. This patch extends the interface to permit userspace to pass a bitmask of loaded key types. It also allows userspace to block loading of a symmetric key in order to avoid a compromised system from being able to load an additional key type later.

Rafael J. Wysocki	0759e80b84	PM / QoS: Fix device resume latency framework ... The special value of 0 for device resume latency PM QoS means "no restriction", but there are two problems with that. First, device resume latency PM QoS requests with 0 as the value are always put in front of requests with positive values in the priority lists used internally by the PM QoS framework, causing 0 to be chosen as an effective constraint value. However, that 0 is then interpreted as "no restriction" effectively overriding the other requests with specific restrictions which is incorrect. Second, the users of device resume latency PM QoS have no way to specify that *any* resume latency at all should be avoided, which is an artificial limitation in general. To address these issues, modify device resume latency PM QoS to use S32_MAX as the "no constraint" value and 0 as the "no latency at all" one and rework its users (the cpuidle menu governor, the genpd QoS governor and the runtime PM framework) to follow these changes. Also add a special "n/a" value to the corresponding user space I/F to allow user space to indicate that it cannot accept any resume latencies at all for the given device.

Mario Limonciello	f2645fa317	platform/x86: dell-smbios-wmi: introduce userspace interface ... It's important for the driver to provide a R/W ioctl to ensure that two competing userspace processes don't race to provide or read each others data. This userspace character device will be used to perform SMBIOS calls from any applications. It provides an ioctl that will allow passing the WMI calling interface buffer between userspace and kernel space. This character device is intended to deprecate the dcdbas kernel module and the interface that it provides to userspace. To perform an SMBIOS IOCTL call using the character device userspace will perform a read() on the the character device. The WMI bus will provide a u64 variable containing the necessary size of the IOCTL buffer. The API for interacting with this interface is defined in documentation as well as the WMI uapi header provides the format of the structures. Not all userspace requests will be accepted. The dell-smbios filtering functionality will be used to prevent access to certain tokens and calls. All whitelisted commands and tokens are now shared out to userspace so applications don't need to define them in their own headers.
