commit 9547837bdccb4af127528b36a73377150658b4ac upstream.

The (1292:4745) Innomedia INNEX GENESIS/ATARI adapter needs
HID_QUIRK_MULTI_INPUT to split the device up into two controllers
instead of inputs from both being merged into one.

commit 4f65245f2d178b9cba48350620d76faa4a098841 upstream.

uref-&gt;field_index, uref-&gt;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-&gt;field' (local cap)
drivers/hid/usbhid/hiddev.c:477 hiddev_ioctl_usage() warn: potential spectre issue 'field-&gt;usage' (local cap)
drivers/hid/usbhid/hiddev.c:757 hiddev_ioctl() warn: potential spectre issue 'report-&gt;field' (local cap)
drivers/hid/usbhid/hiddev.c:801 hiddev_ioctl() warn: potential spectre issue 'hid-&gt;collection' (local cap)

Fix this by sanitizing such structure fields before using them to index
report-&gt;field, field-&gt;usage and hid-&gt;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].

commit ef6eaf27274c0351f7059163918f3795da13199c upstream.

Commit ac75a041048b ("HID: i2c-hid: fix size check and type usage") started
writing messages when the ret_size is &lt;= 2 from i2c_master_recv.  However, my
device i2c-DLL07D1 returns 2 for a short period of time (~0.5s) after I stop
moving the pointing stick or touchpad.  It varies, but you get ~50 messages
each time which spams the log hard.

[  95.925055] i2c_hid i2c-DLL07D1:01: i2c_hid_get_input: incomplete report (83/2)

This has also been observed with a i2c-ALP0017.

[ 1781.266353] i2c_hid i2c-ALP0017:00: i2c_hid_get_input: incomplete report (30/2)

Only print the message when ret_size is totally invalid and less than 2 to cut
down on the log spam.

[ Upstream commit 7ad81482cad67cbe1ec808490d1ddfc420c42008 ]

We get the "new_profile_index" value from the mouse device when we're
handling raw events.  Smatch taints it as untrusted data and complains
that we need a bounds check.  This seems like a reasonable warning
otherwise there is a small read beyond the end of the array.

<title>HID: hidraw: Fix crash on HIDIOCGFEATURE with a destroyed device</title>

commit a955358d54695e4ad9f7d6489a7ac4d69a8fc711 upstream.

Doing `ioctl(HIDIOCGFEATURE)` in a tight loop on a hidraw device
and then disconnecting the device, or unloading the driver, can
cause a NULL pointer dereference.

When a hidraw device is destroyed it sets 0 to `dev-&gt;exist`.
Most functions check 'dev-&gt;exist' before doing its work, but
`hidraw_get_report()` was missing that check.

[ Upstream commit 9abd04af951e5734c9d5cfee9b49790844b734cf ]

ELO devices have one Button usage in GenDesk field, which makes hid-input map
it to BTN_LEFT; that confuses userspace, which then considers the device to be
a mouse/touchpad instead of touchscreen.

Fix that by unmapping BTN_LEFT and keeping only BTN_TOUCH in place.

[ Upstream commit 9abd04af951e5734c9d5cfee9b49790844b734cf ]

ELO devices have one Button usage in GenDesk field, which makes hid-input map
it to BTN_LEFT; that confuses userspace, which then considers the device to be
a mouse/touchpad instead of touchscreen.

Fix that by unmapping BTN_LEFT and keeping only BTN_TOUCH in place.
