e1000e: Fix e1000_check_for_copper_link_ich8lan return value.

2018-01-17T08:29:31+00:00

commit 4110e02eb45ea447ec6f5459c9934de0a273fb91 upstream.

e1000e_check_for_copper_link() and e1000_check_for_copper_link_ich8lan()
are the two functions that may be assigned to mac.ops.check_for_link when
phy.media_type == e1000_media_type_copper. Commit 19110cfbb34d ("e1000e:
Separate signaling for link check/link up") changed the meaning of the
return value of check_for_link for copper media but only adjusted the first
function. This patch adjusts the second function likewise.

uas: ignore UAS for Norelsys NS1068(X) chips

2018-01-17T08:29:31+00:00

commit 928afc85270753657b5543e052cc270c279a3fe9 upstream.

The UAS mode of Norelsys NS1068(X) is reported to fail to work on
several platforms with the following error message:

xhci-hcd xhci-hcd.0.auto: ERROR Transfer event for unknown stream ring slot 1 ep 8
xhci-hcd xhci-hcd.0.auto: @00000000bf04a400 00000000 00000000 1b000000 01098001

And when trying to mount a partition on the disk the disk will
disconnect from the USB controller, then after re-connecting the device
will be offlined and not working at all.

Falling back to USB mass storage can solve this problem, so ignore UAS
function of this chip.

Bluetooth: Prevent stack info leak from the EFS element.

2018-01-17T08:29:31+00:00

commit 06e7e776ca4d36547e503279aeff996cbb292c16 upstream.

In the function l2cap_parse_conf_rsp and in the function
l2cap_parse_conf_req the following variable is declared without
initialization:

struct l2cap_conf_efs efs;

In addition, when parsing input configuration parameters in both of
these functions, the switch case for handling EFS elements may skip the
memcpy call that will write to the efs variable:

...
case L2CAP_CONF_EFS:
if (olen == sizeof(efs))
memcpy(&efs, (void *)val, olen);
...

The olen in the above if is attacker controlled, and regardless of that
if, in both of these functions the efs variable would eventually be
added to the outgoing configuration request that is being built:

l2cap_add_conf_opt(&ptr, L2CAP_CONF_EFS, sizeof(efs), (unsigned long) &efs);

So by sending a configuration request, or response, that contains an
L2CAP_CONF_EFS element, but with an element length that is not
sizeof(efs) - the memcpy to the uninitialized efs variable can be
avoided, and the uninitialized variable would be returned to the
attacker (16 bytes).

This issue has been assigned CVE-2017-1000410

staging: android: ashmem: fix a race condition in ASHMEM_SET_SIZE ioctl

2018-01-17T08:29:31+00:00

commit 443064cb0b1fb4569fe0a71209da7625129fb760 upstream.

A lock-unlock is missing in ASHMEM_SET_SIZE ioctl which can result in a
race condition when mmap is called. After the !asma->file check, before
setting asma->size, asma->file can be set in mmap. That would result in
having different asma->size than the mapped memory size. Combined with
ASHMEM_UNPIN ioctl and shrinker invocation, this can result in memory
corruption.

usbip: remove kernel addresses from usb device and urb debug msgs

2018-01-17T08:29:31+00:00

commit e1346fd87c71a1f61de1fe476ec8df1425ac931c upstream.

usbip_dump_usb_device() and usbip_dump_urb() print kernel addresses.
Remove kernel addresses from usb device and urb debug msgs and improve
the message content.

Instead of printing parent device and bus addresses, print parent device
and bus names.

USB: fix usbmon BUG trigger

2018-01-17T08:29:31+00:00

commit 46eb14a6e1585d99c1b9f58d0e7389082a5f466b upstream.

Automated tests triggered this by opening usbmon and accessing the
mmap while simultaneously resizing the buffers. This bug was with
us since 2006, because typically applications only size the buffers
once and thus avoid racing. Reported by Kirill A. Shutemov.

usb: misc: usb3503: make sure reset is low for at least 100us

2018-01-17T08:29:31+00:00

commit b8626f1dc29d3eee444bfaa92146ec7b291ef41c upstream.

When using a GPIO which is high by default, and initialize the
driver in USB Hub mode, initialization fails with:
  [  111.757794] usb3503 0-0008: SP_ILOCK failed (-5)

The reason seems to be that the chip is not properly reset.
Probe does initialize reset low, however some lines later the
code already set it back high, which is not long enouth.

Make sure reset is asserted for at least 100us by inserting a
delay after initializing the reset pin during probe.
