HID: hiddev: fix potential Spectre v1

2018-07-11T14:31:31+00:00

commit 4f65245f2d178b9cba48350620d76faa4a098841 upstream. uref->field_index, uref->usage_index, finfo.field_index and cinfo.index can be indirectly controlled by user-space, hence leading to a potential exploitation of the Spectre variant 1 vulnerability. This issue was detected with the help of Smatch: drivers/hid/usbhid/hiddev.c:473 hiddev_ioctl_usage() warn: potential spectre issue 'report->field' (local cap) drivers/hid/usbhid/hiddev.c:477 hiddev_ioctl_usage() warn: potential spectre issue 'field->usage' (local cap) drivers/hid/usbhid/hiddev.c:757 hiddev_ioctl() warn: potential spectre issue 'report->field' (local cap) drivers/hid/usbhid/hiddev.c:801 hiddev_ioctl() warn: potential spectre issue 'hid->collection' (local cap) Fix this by sanitizing such structure fields before using them to index report->field, field->usage and hid->collection Notice that given that speculation windows are large, the policy is to kill the speculation on the first load and not worry if it can be completed with a dependent load/store [1].

HID: usbhid: extend the polling interval configuration to keyboards

2018-03-23T13:48:37+00:00

For mouse and joystick devices user can change the polling interval via usbhid.mousepoll and usbhid.jspoll. Implement the same thing for keyboards, so user can reduce(or increase) input latency this way. This has been tested with a Cooler Master Devastator with kbpoll=32, resulting in delay between events of 32 ms(values were taken from evtest). Signed-off-by: Filip Alac Signed-off-by: Jiri Kosina

vfs: do bulk POLL* -> EPOLL* replacement

2018-02-11T22:34:03+00:00

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 $L; do sed -i "-es/^$[^\"]*$$\$/\\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 Signed-off-by: Linus Torvalds

HID: Ignore Jabra HID interface based on firmware version

2017-11-21T11:54:58+00:00

Two Jabra speakerphone devices were added to the ignore list in 2013, because the device HID interfaces didn't work well with kernel usbhid driver, and could cause volume key event storm. See the original commit: Commit 31b9779cb292 ("HID: ignore Jabra speakerphones HID interface") Modify hid_lookup_quirk() to consider the firmware version of these two devices, so that only versions older than a known good version are ignored.

HID: core: move the dynamic quirks handling in core

2017-11-21T10:14:48+00:00

usbhid has a list of dynamic quirks in addition to a list of static quirks. There is not much USB specific in that, so move this part of the module in core so we can have one central place for quirks. Signed-off-by: Benjamin Tissoires Signed-off-by: Jiri Kosina
