There were a couple of bugs in some of the higher-level functions, which aren't actually being called in today's kernel, but surfaced as a result of converting existing radix tree & IDR users over to the XArray. Some of the other changes to how the higher-level APIs work were also motivated by converting various users; again, they're not in use in today's kernel, so changing them has a low probability of introducing a bug.

2018-11-22Revert "Input: Add the `REL_WHEEL_HI_RES` event code"Benjamin Tissoires1-10/+1
This reverts commit aaf9978c3c0291ef3beaa97610bc9c3084656a85. Quoting Peter: There is a HID feature report called "Resolution Multiplier" Described in the "Enhanced Wheel Support in Windows" doc and the "USB HID Usage Tables" page 30. http://download.microsoft.com/download/b/d/1/bd1f7ef4-7d72-419e-bc5c-9f79ad7bb66e/wheel.docx https://www.usb.org/sites/default/files/documents/hut1_12v2.pdf This was new for Windows Vista, so we're only a decade behind here. I only accidentally found this a few days ago while debugging a stuck button on a Microsoft mouse. The docs above describe it like this: a wheel control by default sends value 1 per notch. If the resolution multiplier is active, the wheel is expected to send a value of $multiplier per notch (e.g. MS Sculpt mouse) or just send events more often, i.e. for less physical motion (e.g. MS Comfort mouse). For the latter, you need the right HW of course. The Sculpt mouse has tactile wheel clicks, so nothing really changes. The Comfort mouse has continuous motion with no tactile clicks. Similar to the free-wheeling Logitech mice but without any inertia. Note that the doc also says that Vista and onwards *always* enable this feature where available. An example HID definition looks like this: Usage Page Generic Desktop (0x01) Usage Resolution Multiplier (0x48) Logical Minimum 0 Logical Maximum 1 Physical Minimum 1 Physical Maximum 16 Report Size 2 # in bits Report Count 1 Feature (Data, Var, Abs) So the actual bits have values 0 or 1 and that reflects real values 1 or 16. We've only seen single-bits so far, so there's low-res and hi-res, but nothing in between. The multiplier is available for HID usages "Wheel" and "AC Pan" (horiz wheel). Microsoft suggests that > Vendors should ship their devices with smooth scrolling disabled and allow > Windows to enable it. This ensures that the device works like a regular HID > device on legacy operating systems that do not support smooth scrolling. (see the wheel doc linked above) The mice that we tested so far do reset on unplug. Device Support looks to be all (?) Microsoft mice but nothing else Not supported: - Logitech G500s, G303 - Roccat Kone XTD - all the cheap Lenovo, HP, Dell, Logitech USB mice that come with a workstation that I could find don't have it. - Etekcity something something - Razer Imperator Supported: - Microsoft Comfort Optical Mouse 3000 - yes, physical: 1:4 - Microsoft Sculpt Ergonomic Mouse - yes, physical: 1:12 - Microsoft Surface mouse - yes, physical: 1:4 So again, I think this is really just available on Microsoft mice, but probably all decent MS mice released over the last decade. Looking at the hardware itself: - no noticeable notches in the weel - low-res: 18 events per 360deg rotation (click angle 20 deg) - high-res: 72 events per 360deg → matches multiplier of 4 - I can feel the notches during wheel turns - low-res: 24 events per 360 deg rotation (click angle 15 deg) - horiz wheel is tilt-based, continuous output value 1 - high-res: 24 events per 360deg with value 12 → matches multiplier of 12 - horiz wheel output rate doubles/triples?, values is 3 - It's a touch strip, not a wheel so no notches - high-res: events have value 4 instead of 1 a bit strange given that it doesn't actually have notches. Ok, why is this an issue for the current API? First, because the logitech multiplier used in Harry's patches looks suspiciously like the Resolution Multiplier so I think we should assume it's the same thing. Nestor, can you shed some light on that? - `REL_WHEEL` is defined as the number of notches, emulated where needed. - `REL_WHEEL_HI_RES` is the movement of the user's finger in microns. - `WM_MOUSEWHEEL` (Windows) is is a multiple of 120, defined as "the threshold for action to be taken and one such action" https://docs.microsoft.com/en-us/windows/desktop/inputdev/wm-mousewheel If the multiplier is set to M, this means we need an accumulated value of M until we can claim there was a wheel click. So after enabling the multiplier and setting it to the maximum (like Windows): - M units are 15deg rotation → 1 unit is 2620/M micron (see below). This is the `REL_WHEEL_HI_RES` value. - wheel diameter 20mm: 15 deg rotation is 2.62mm, 2620 micron (pi * 20mm / (360deg/15deg)) - For every M units accumulated, send one `REL_WHEEL` event The problem here is that we've now hardcoded 20mm/15 deg into the kernel and we have no way of getting the size of the wheel or the click angle into the kernel. In userspace we now have to undo the kernel's calculation. If our click angle is e.g. 20 degree we have to undo the (lossy) calculation from the kernel and calculate the correct angle instead. This also means the 15 is a hardcoded option forever and cannot be changed. In hid-logitech-hidpp.c, the microns per unit is hardcoded per device. Harry, did you measure those by hand? We'd need to update the kernel for every device and there are 10 years worth of devices from MS alone. The multiplier default is 8 which is in the right ballpark, so I'm pretty sure this is the same as the Resolution Multiplier, just in HID++ lingo. And given that the 120 magic factor is what Windows uses in the end, I can't imagine Logitech rolling their own thing here. Nestor? And we're already fairly inaccurate with the microns anyway. The MX Anywhere 2S has a click angle of 20 degrees (18 stops) and a 17mm wheel, so a wheel notch is approximately 2.67mm, one event at multiplier 8 (1/8 of a notch) would be 334 micron. That's only 80% of the fallback value of 406 in the kernel. Multiplier 6 gives us 445micron (10% off). I'm assuming multiplier 7 doesn't exist because it's not a factor of 120. Summary: Best option may be to simply do what Windows is doing, all the HW manufacturers have to use that approach after all. Switch `REL_WHEEL_HI_RES` to report in fractions of 120, with 120 being one notch and divide that by the multiplier for the actual events. So e.g. the Logitech multiplier 8 would send value 15 for each event in hi-res mode. This can be converted in userspace to whatever userspace needs (combined with a hwdb there that tells you wheel size/click angle/...).

2018-11-20Documentation/security-bugs: Postpone fix publication in exceptional casesWill Deacon1-10/+11
At the request of the reporter, the Linux kernel security team offers to postpone the publishing of a fix for up to 5 business days from the date of a report. While it is generally undesirable to keep a fix private after it has been developed, this short window is intended to allow distributions to package the fix into their kernel builds and permits early inclusion of the security team in the case of a co-ordinated disclosure with other parties. Unfortunately, discussions with major Linux distributions and cloud providers has revealed that 5 business days is not sufficient to achieve either of these two goals. As an example, cloud providers need to roll out KVM security fixes to a global fleet of hosts with sufficient early ramp-up and monitoring. An end-to-end timeline of less than two weeks dramatically cuts into the amount of early validation and increases the chance of guest-visible regressions. The consequence of this timeline mismatch is that security issues are commonly fixed without the involvement of the Linux kernel security team and are instead analysed and addressed by an ad-hoc group of developers across companies contributing to Linux. In some cases, mainline (and therefore the official stable kernels) can be left to languish for extended periods of time. This undermines the Linux kernel security process and puts upstream developers in a difficult position should they find themselves involved with an undisclosed security problem that they are unable to report due to restrictions from their employer. To accommodate the needs of these users of the Linux kernel and encourage them to engage with the Linux security team when security issues are first uncovered, extend the maximum period for which fixes may be delayed to 7 calendar days, or 14 calendar days in exceptional cases, where the logistics of QA and large scale rollouts specifically need to be accommodated. This brings parity with the linux-distros@ maximum embargo period of 14 calendar days.

2018-11-15rxrpc: Fix life checkDavid Howells1-6/+11
The life-checking function, which is used by kAFS to make sure that a call is still live in the event of a pending signal, only samples the received packet serial number counter; it doesn't actually provoke a change in the counter, rather relying on the server to happen to give us a packet in the time window. Fix this by adding a function to force a ping to be transmitted. kAFS then keeps track of whether there's been a stall, and if so, uses the new function to ping the server, resetting the timeout to allow the reply to come back. If there's a stall, a ping and the call is *still* stalled in the same place after another period, then the call will be aborted.

First we have a patch by Oliver Hartkopp which changes the raw socket's raw_sendmsg() to return an error value if the user tries to send a CANFD frame to a CAN-2.0 device. The next two patches are by Jimmy Assarsson and fix potential problems in the kvaser_usb driver. YueHaibing's patches for the ucan driver fix a compile time warning and remove a duplicate include. Eugeniu Rosca patch adds more binding documentation to the rcar_can driver bindings. The next two patches are by Fabrizio Castro for the rcar_can driver and fixes a problem in the driver's probe function and document the r8a774a1 binding. Lukas Wunner's patch fixes a recpetion problem in hi311x driver by switching from edge to level triggered interruts. The next three patches all target the flexcan driver. Pankaj Bansal's patch unconditionally unlocks the last mailbox used for RX. Alexander Stein provides a better workaround for a hardware limitation when sending RTR frames, by using the last mailbox for TX, resulting in fewer lost frames. The patch by me simplyfies the driver, by making a runtime value a compile time constant. The following 4 patches are by me and provide the groundwork for the next patches by Oleksij Rempel. To avoid code duplication common code in the common CAN driver infrastructure is factured out and error handling is cleaned up. The next 4 patches are by Oleksij Rempel and fix the problem in the flexcan driver that other processes see TX frames arrive out of order with ragards to a RX'ed frame (which are send by a different system on the CAN bus as the result of our TX frame). ==================== Signed-off-by: David S.

2018-11-12dt-bindings: phy-qcom-qmp: Fix several mistakes from prior commitsDouglas Anderson1-8/+23
Digging through the "phy-qcom-qmp" showed me many inconsistencies between the bindings and the reality of the driver. Let's fix them all. * In commit 2d66eab18375 ("dt-bindings: phy: qmp: Add support for QMP phy in IPQ8074") we probably should have explicitly listed that there are no clocks for this PHY and also added the reset names in alphabetical order. You can see that there are no clocks in the driver where "clk_list" is NULL. * In commit 8587b220f05e ("dt-bindings: phy-qcom-qmp: Update bindings for QMP V3 USB PHY") we probably should have listed the resets for this new PHY and also removed the "(Optional)" marking for the "cfg" reset since PHYs that need "cfg" really do need it. It's just that not all PHYs need it. * In commit 7f0802074120 ("dt-bindings: phy-qcom-qmp: Update bindings for sdm845") we forgot to update one instance of the string "qcom,qmp-v3-usb3-phy" to be "qcom,sdm845-qmp-usb3-phy". Let's fix that. We should also have added "qcom,sdm845-qmp-usb3-uni-phy" to the clock-names and reset-names lists. * In commit 99c7c7364b71 ("dt-bindings: phy-qcom-qmp: Add UFS phy compatible string for sdm845") we should have added the set of clocks and resets for "qcom,sdm845-qmp-ufs-phy". These were taken from the driver. * Cleanup the wording for what properties child nodes have to make it more obvious which types of PHYs need clocks and resets. This was sorta implicit in the "-names" description but I found myself confused. * As per the code not all "pcie qmp phys" have resets. Specifically note that the "has_lane_rst" property in the driver is false for "ipq8074-qmp-pcie-phy". Thus make it clear exactly which PHYs need child nodes with resets.

2018-11-09can: hi311x: Use level-triggered interruptLukas Wunner1-1/+1
If the hi3110 shares the SPI bus with another traffic-intensive device and packets are received in high volume (by a separate machine sending with "cangen -g 0 -i -x"), reception stops after a few minutes and the counter in /proc/interrupts stops incrementing. Bus state is "active". Bringing the interface down and back up reconvenes the reception. The issue is not observed when the hi3110 is the sole device on the SPI bus. Using a level-triggered interrupt makes the issue go away and lets the hi3110 successfully receive 2 GByte over the course of 5 days while a ks8851 Ethernet chip on the same SPI bus handles 6 GByte of traffic. Unfortunately the hi3110 datasheet is mum on the trigger type.

2018-11-06x86/mm: Move LDT remap out of KASLR region on 5-level pagingKirill A. Shutemov1-16/+18
On 5-level paging the LDT remap area is placed in the middle of the KASLR randomization region and it can overlap with the direct mapping, the vmalloc or the vmap area. The LDT mapping is per mm, so it cannot be moved into the P4D page table next to the CPU_ENTRY_AREA without complicating PGD table allocation for 5-level paging. The 4 PGD slot gap just before the direct mapping is reserved for hypervisors, so it cannot be used. Move the direct mapping one slot deeper and use the resulting gap for the LDT remap area. The resulting layout is the same for 4 and 5 level paging. [ tglx: Massaged changelog ] Fixes: f55f0501cbf6 ("x86/pti: Put the LDT in its own PGD if PTI is on") Signed-off-by: Kirill A.

Pull block layer fixes from Jens Axboe: "The biggest part of this pull request is the revert of the blkcg cleanup series. It had one fix earlier for a stacked device issue, but another one was reported. Rather than play whack-a-mole with this, revert the entire series and try again for the next kernel release. Apart from that, only small fixes/changes. Summary: - Indentation fixup for mtip32xx (Colin Ian King) - The blkcg cleanup series revert (Dennis Zhou) - Two NVMe fixes. One fixing a regression in the nvme request initialization in this merge window, causing nvme-fc to not work. The other is a suspend/resume p2p resource issue (James, Keith) - Fix sg discard merge, allowing us to merge in cases where we didn't before (Jianchao Wang) - Call rq_qos_exit() after the queue is frozen, preventing a hang (Ming) - Fix brd queue setup, fixing an oops if we fail setting up all devices (Ming)" * tag 'for-linus-20181102' of git://git.kernel.dk/linux-block: nvme-pci: fix conflicting p2p resource adds nvme-fc: fix request private initialization blkcg: revert blkcg cleanups series block: brd: associate with queue until adding disk block: call rq_qos_exit() after queue is frozen mtip32xx: clean an indentation issue, remove extraneous tabs block: fix the DISCARD request merge
