2018-02-11vfs: do bulk POLL* -> EPOLL* replacementLinus Torvalds6-10/+10
This is the mindless scripted replacement of kernel use of POLL* variables as described by Al, done by this script: for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'` for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done done with de-mangling cleanups yet to come. NOTE! On almost all architectures, the EPOLL* constants have the same values as the POLL* constants do. But they keyword here is "almost". For various bad reasons they aren't the same, and epoll() doesn't actually work quite correctly in some cases due to this on Sparc et al. The next patch from Al will sort out the final differences, and we should be all done. Scripted-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull poll annotations from Al Viro: "This introduces a __bitwise type for POLL### bitmap, and propagates the annotations through the tree. Most of that stuff is as simple as 'make ->poll() instances return __poll_t and do the same to local variables used to hold the future return value'. Some of the obvious brainos found in process are fixed (e.g. POLLIN misspelled as POLL_IN). At that point the amount of sparse warnings is low and most of them are for genuine bugs - e.g. ->poll() instance deciding to return -EINVAL instead of a bitmap. I hadn't touched those in this series - it's large enough as it is. Another problem it has caught was eventpoll() ABI mess; select.c and eventpoll.c assumed that corresponding POLL### and EPOLL### were equal. That's true for some, but not all of them - EPOLL### are arch-independent, but POLL### are not. The last commit in this series separates userland POLL### values from the (now arch-independent) kernel-side ones, converting between them in the few places where they are copied to/from userland. AFAICS, this is the least disruptive fix preserving poll(2) ABI and making epoll() work on all architectures. As it is, it's simply broken on sparc - try to give it EPOLLWRNORM and it will trigger only on what would've triggered EPOLLWRBAND on other architectures. EPOLLWRBAND and EPOLLRDHUP, OTOH, are never triggered at all on sparc.

2018-01-23HID: quirks: Fix keyboard + touchpad on Toshiba Click Mini not workingHans de Goede1-1/+11
The Toshiba Click Mini uses an i2c attached keyboard/touchpad combo (single i2c_hid device for both) which has a vid:pid of 04F3:0401, which is also used by a bunch of Elan touchpads which are handled by the drivers/input/mouse/elan_i2c driver, but that driver deals with pure touchpads and does not work for a combo device such as the one on the Toshiba Click Mini. The combo on the Mini has an ACPI id of ELAN0800, which is not claimed by the elan_i2c driver, so check for that and if it is found do not ignore the device. This fixes the keyboard/touchpad combo on the Mini not working (although with the touchpad in mouse emulation mode).

2018-01-23HID: wacom: Fix reporting of touch toggle (WACOM_HID_WD_MUTE_DEVICE) eventsJason Gerecke1-8/+8
Touch toggle softkeys send a '1' while pressed and a '0' while released, requring the kernel to keep track of wether touch should be enabled or disabled. The code does not handle the state transitions properly, however. If the key is pressed repeatedly, the following four states of states are cycled through (assuming touch starts out enabled): Press: shared->is_touch_on => 0, SW_MUTE_DEVICE => 1 Release: shared->is_touch_on => 0, SW_MUTE_DEVICE => 1 Press: shared->is_touch_on => 1, SW_MUTE_DEVICE => 0 Release: shared->is_touch_on => 1, SW_MUTE_DEVICE => 1 The hardware always properly enables/disables touch when the key is pressed but applications that listen for SW_MUTE_DEVICE events to provide feedback about the state will only ever show touch as being enabled while the key is held, and only every-other time. This sequence occurs because the fallthrough WACOM_HID_WD_TOUCHONOFF case is always handled, and it uses the value of the *local* is_touch_on variable as the value to report to userspace. The local value is equal to the shared value when the button is pressed, but equal to zero when the button is released. Reporting the shared value to userspace fixes this problem, but the fallthrough case needs to update the shared value in an incompatible way (which is why the local variable was introduced in the first place). To work around this, we just handle both cases in a single block of code and update the shared variable as appropriate.

2018-01-23HID: elecom: rewrite report fixup for EX-G and future miceTomasz Kramkowski4-36/+47
This patch rewrites the mouse report fixup used for the DEFT and HUGE elecom trackballs in order to make it generic enough to fix other elecom mice with similar issues. This patch also uses this new report fixup function to fix the Elecom EX-G trackball which has 6 physical buttons and a similar issue to the other two mice. Elecom's track record has so far shown that they like to re-use the same report descriptor for multiple different mice regardless of the number of buttons the mouse has. This means that the missing buttons on multiple mice can be fixed in one function without introducing phantom buttons which would in turn cause the number of mouse buttons to be misreported to userspace. This patch drops the very verbose report descriptor "diff" comment for a more abridged yet hopefully just as informative generic version.

2018-01-23HID: wacom: EKR: ensure devres groups at higher indexes are releasedAaron Armstrong Skomra1-12/+12
Background: ExpressKey Remotes communicate their events via usb dongle. Each dongle can hold up to 5 pairings at one time and one EKR (identified by its serial number) can unfortunately be paired with its dongle more than once. The pairing takes place in a round-robin fashion. Input devices are only created once per EKR, when a new serial number is seen in the list of pairings. However, if a device is created for a "higher" paring index and subsequently a second pairing occurs at a lower pairing index, unpairing the remote with that serial number from any pairing index will currently cause a driver crash. This occurs infrequently, as two remotes are necessary to trigger this bug and most users have only one remote. As an illustration, to trigger the bug you need to have two remotes, and pair them in this order: 1. slot 0 -> remote 1 (input device created for remote 1) 2. slot 1 -> remote 1 (duplicate pairing - no device created) 3. slot 2 -> remote 1 (duplicate pairing - no device created) 4. slot 3 -> remote 1 (duplicate pairing - no device created) 5. slot 4 -> remote 2 (input device created for remote 2) 6. slot 0 -> remote 2 (1 destroyed and recreated at slot 1) 7. slot 1 -> remote 2 (1 destroyed and recreated at slot 2) 8. slot 2 -> remote 2 (1 destroyed and recreated at slot 3) 9. slot 3 -> remote 2 (1 destroyed and not recreated) 10. slot 4 -> remote 2 (2 was already in this slot so no changes) 11. slot 0 -> remote 1 (The current code sees remote 2 was paired over in one of the dongle slots it occupied and attempts to remove all information about remote 2 [1]. It calls wacom_remote_destroy_one for remote 2, but the destroy function assumes the lowest index is where the remote's input device was created. The code "cleans up" the other remote 2 pairings including the one which the input device was based on, assuming they were were just duplicate pairings. However, the cleanup doesn't call the devres release function for the input device that was created in slot 4). This issue is fixed by this commit. [1] Remote 2 should subsequently be re-created on the next packet from the EKR at the lowest numbered slot that it occupies (here slot 1).

2017-11-22HID: multitouch: Combine all left-button events in a frameHans de Goede1-0/+20
According to the Win8 Precision Touchpad spec, inside the HID_UP_BUTTON usage-page usage 1 is for a clickpad getting clicked, 2 for an external left button and 3 for an external right button. Since Linux uses BTN_LEFT for a clickpad being clicked we end up mapping both usage 1 and 2 to BTN_LEFT and if a single report contains both then we ended up always reporting the value of both in a single SYN, e.g. : BTN_LEFT 1, BTN_LEFT 0, SYN. This happens for example with Hantick HTT5288 i2c mt touchpads. This commit fixes this by not immediately reporting left button when we parse the report, but instead storing or-ing together the values and reporting the result from mt_sync_frame() when we've a complete frame.

2017-11-21treewide: setup_timer() -> timer_setup()Kees Cook3-11/+9
This converts all remaining cases of the old setup_timer() API into using timer_setup(), where the callback argument is the structure already holding the struct timer_list. These should have no behavioral changes, since they just change which pointer is passed into the callback with the same available pointers after conversion. It handles the following examples, in addition to some other variations. Casting from unsigned long: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... setup_timer(&ptr->my_timer, my_callback, ptr); and forced object casts: void my_callback(struct something *ptr) { ... } ... setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr); become: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... timer_setup(&ptr->my_timer, my_callback, 0); Direct function assignments: void my_callback(unsigned long data) { struct something *ptr = (struct something *)data; ... } ... ptr->my_timer.function = my_callback; have a temporary cast added, along with converting the args: void my_callback(struct timer_list *t) { struct something *ptr = from_timer(ptr, t, my_timer); ... } ... ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback; And finally, callbacks without a data assignment: void my_callback(unsigned long data) { ... } ... setup_timer(&ptr->my_timer, my_callback, 0); have their argument renamed to verify they're unused during conversion: void my_callback(struct timer_list *unused) { ... } ... timer_setup(&ptr->my_timer, my_callback, 0); The conversion is done with the following Coccinelle script: spatch --very-quiet --all-includes --include-headers \ -I ./arch/x86/include -I ./arch/x86/include/generated \ -I ./include -I ./arch/x86/include/uapi \ -I ./arch/x86/include/generated/uapi -I ./include/uapi \ -I ./include/generated/uapi --include ./include/linux/kconfig.h \ --dir . \ --cocci-file ~/src/data/timer_setup.cocci @fix_address_of@ expression e;

2017-11-21HID: cp2112: Fix I2C_BLOCK_DATA transactionsEudean Sun1-2/+13
The existing driver erroneously treats I2C_BLOCK_DATA and BLOCK_DATA commands the same. For I2C_BLOCK_DATA reads, the length of the read is provided in data->block[0], but the length itself should not be sent to the slave. In contrast, for BLOCK_DATA reads no length is specified since the length will be the first byte returned from the slave. When copying data back to the data buffer, for an I2C_BLOCK_DATA read we have to take care not to overwrite data->block[0] to avoid overwriting the length. A BLOCK_DATA read doesn't have this concern since the first byte returned by the device is the length and belongs in data->block[0]. For I2C_BLOCK_DATA writes, the length is also provided in data->block[0], but the length itself is not sent to the slave (in contrast to BLOCK_DATA writes where the length prefixes the data sent to the slave). This was tested on physical hardware using i2cdump with the i and s flags to test the behavior of I2C_BLOCK_DATA reads and BLOCK_DATA reads, respectively. Writes were not tested but the I2C_BLOCK_DATA write change is pretty simple to verify by inspection. Signed-off-by: Eudean Sun <eudean@arista.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2017-11-21HID: wacom: Queue events with missing type/serial data for later processingJason Gerecke3-0/+114
Userspace expects to receive tool type and serial number information for the active pen in the very first kernel report, if such data is supported by the hardware. While this expectation is not an issue for EMR devices, AES sensors will often send several packets worth of in- range data before relaying type/serial data to the kernel. Sending this data "late" can result in proximity-tracking issues by xf86-input-wacom, or an inability to distinguish different pens by input-wacom. Options for dealing with this situation include ignoring reports from the tablet until we get the necessary data, or using the information from the last-seen pen instead of the (eventual) real data. Neither option is particularly attractive: the former results in truncated strokes and the latter causes issues with switching between pens. This commit instead opts to queue up events with missing information until we receive a report which contains it. At that point, we can update the driver's state variables (id[0] and serial[0]) and replay the queued events.

Current AES sensors relay tool type and serial number information with a different set of usages than those prescribed by the modern (i.e. MobileStudio Pro and newer) EMR tablet standard. To ensure the driver properly understands these usages, we modify them to be compatible. The identifying information is split across three consecutive fields: a 16-bit WACOM_HID_WT_SERIALNUMBER (which is more accurately described as WACOM_HID_WD_TOOLTYPE), a 32-bit HID_DG_TOOLSERIALNUMBER, and an 8-bit 0xFF000000 (which should be WACOM_HID_WD_SERIALHI). While we're at it, we also define proper min/max values since may may be undefined on some devices.

2017-11-21HID: core: remove the absolute need of hid_have_special_driver[]Benjamin Tissoires2-29/+115
Most HID devices behave properly when they are used with hid-generic. Since kernel v4.12, we do not poll for input reports at plug in, so hid-generic should behave properly with all HID devices. There has been a long standing list of HID devices that have a special driver. It used to be just a few, but with time, this list went too big, and we can not ask users to know which HID special driver will pick up their device. We can teach hid-generic to be nice with others. If a device is not explicitly marked with HID_QUIRK_HAVE_SPECIAL_DRIVER, we can allow hid-generic to pick up the device as long as no other loaded HID driver will match the device. When the special driver appears, hid-generic can step back and let the special driver handling the device. In case this special driver is removed, this good old pal of hid-generic will rebind to the device. This basically makes the list hid_have_special_driver[] useless. It still allows to not see a hid-generic driver bound and removed during boot, so we can keep it around. This will also help other people to have a special HID driver without the need of recompiling hid-core.
