[PATCH 4.14 01/22] Bluetooth: btusb: Apply QCA Rome patches for some ATH3012 models

[Greg Kroah-Hartman]

From: Takashi Iwai <tiwai@suse.de>

commit 803cdb8ce584198cd45825822910cac7de6378cb upstream.

In commit f44cb4b19ed4 ("Bluetooth: btusb: Fix quirk for Atheros
1525/QCA6174") we tried to address the non-working Atheros BT devices
by changing the quirk from BTUSB_ATH3012 to BTUSB_QCA_ROME.  This made
such devices working while it turned out to break other existing chips
with the very same USB ID, hence it was reverted afterwards.

This is another attempt to tackle the issue.  The essential point to
use BTUSB_QCA_ROME is to apply the btusb_setup_qca() and do RAM-
patching.  And the previous attempt failed because btusb_setup_qca()
returns -ENODEV if the ROM version doesn't match with the expected
ones.  For some devices that have already the "correct" ROM versions,
we may just skip the setup procedure and continue the rest.

So, the first fix we'll need is to add a check of the ROM version in
the function to skip the setup if the ROM version looks already sane,
so that it can be applied for all ath devices.

However, the world is a bit more complex than that simple solution.
Since BTUSB_ATH3012 quirk checks the bcdDevice and bails out when it's
0x0001 at the beginning of probing, so the device probe always aborts
here.

In this patch, we add another check of ROM version again, and if the
device needs patching, the probe continues.  For that, a slight
refactoring of btusb_qca_send_vendor_req() was required so that the
probe function can pass usb_device pointer directly before allocating
hci_dev stuff.

Fixes: commit f44cb4b19ed4 ("Bluetooth: btusb: Fix quirk for Atheros 1525/QCA6174")

[PATCH 4.14 02/22] tracing: Fix check for trace_percpu_buffer validity in get_trace_buf()

With the new osnoise tracer, we are seeing the below splat:

osnoise tracer on ppc64le is triggering osnoise_taint() for negative
duration in get_int_safe_duration() called from
trace_sched_switch_callback()->thread_exit().

The problem though is that the check for a valid trace_percpu_buffer is
incorrect in get_trace_buf(). The check is being done after calculating
the pointer for the current cpu, rather than on the main percpu pointer.
Fix the check to be against trace_percpu_buffer.

[PATCH 4.14 04/22] virtio_pci: Support surprise removal of virtio pci device

[Greg Kroah-Hartman]

From: Parav Pandit <parav@nvidia.com>

commit 43bb40c5b92659966bdf4bfe584fde0a3575a049 upstream.

When a virtio pci device undergo surprise removal (aka async removal in
PCIe spec), mark the device as broken so that any upper layer drivers can
abort any outstanding operation.

When a virtio net pci device undergo surprise removal which is used by a
NetworkManager, a below call trace was observed.

[PATCH 4.14 05/22] ieee802154: atusb: fix uninit value in atusb_set_extended_addr

[Greg Kroah-Hartman]

From: Pavel Skripkin <paskripkin@gmail.com>

commit 754e4382354f7908923a1949d8dc8d05f82f09cb upstream.

Alexander reported a use of uninitialized value in
atusb_set_extended_addr(), that is caused by reading 0 bytes via
usb_control_msg().

Fix it by validating if the number of bytes transferred is actually
correct, since usb_control_msg() may read less bytes, than was requested
by caller.

[PATCH 4.14 07/22] mac80211: initialize variable have_higher_than_11mbit

[Greg Kroah-Hartman]

From: Tom Rix <trix@redhat.com>

commit 68a18ad71378a56858141c4449e02a30c829763e upstream.

Clang static analysis reports this warnings

have_higher_than_11mbit is only set to true some of the time in
ieee80211_get_rates() but is checked all of the time.  So
have_higher_than_11mbit needs to be initialized to false.

[PATCH 4.14 08/22] i40e: fix use-after-free in i40e_sync_filters_subtask()

[Greg Kroah-Hartman]

From: Di Zhu <zhudi2@huawei.com>

commit 3116f59c12bd24c513194cd3acb3ec1f7d468954 upstream.

Using ifconfig command to delete the ipv6 address will cause
the i40e network card driver to delete its internal mac_filter and
i40e_service_task kernel thread will concurrently access the mac_filter.
These two processes are not protected by lock
so causing the following use-after-free problems.

[PATCH 4.14 09/22] i40e: Fix incorrect netdevs real number of RX/TX queues

[Greg Kroah-Hartman]

From: Jedrzej Jagielski <jedrzej.jagielski@intel.com>

commit e738451d78b2f8a9635d66c6a87f304b4d965f7a upstream.

There was a wrong queues representation in sysfs during
driver's reinitialization in case of online cpus number is
less than combined queues. It was caused by stopped
NetworkManager, which is responsible for calling vsi_open
function during driver's initialization.
In specific situation (ex. 12 cpus online) there were 16 queues
in /sys/class/net/<iface>/queues. In case of modifying queues with
value higher, than number of online cpus, then it caused write
errors and other errors.
Add updating of sysfs's queues representation during driver
initialization.

[PATCH 4.14 10/22] ipv6: Check attribute length for RTA_GATEWAY in multipath route

[Greg Kroah-Hartman]

From: David Ahern <dsahern@kernel.org>

commit 4619bcf91399f00a40885100fb61d594d8454033 upstream.

Commit referenced in the Fixes tag used nla_memcpy for RTA_GATEWAY as
does the current nla_get_in6_addr. nla_memcpy protects against accessing
memory greater than what is in the attribute, but there is no check
requiring the attribute to have an IPv6 address. Add it.

[PATCH 4.14 13/22] xfs: map unwritten blocks in XFS_IOC_{ALLOC,FREE}SP just like fallocate

[Greg Kroah-Hartman]

From: Darrick J. Wong <djwong@kernel.org>

commit 983d8e60f50806f90534cc5373d0ce867e5aaf79 upstream.

The old ALLOCSP/FREESP ioctls in XFS can be used to preallocate space at
the end of files, just like fallocate and RESVSP.  Make the behavior
consistent with the other ioctls.

[PATCH 4.14 14/22] power: reset: ltc2952: Fix use of floating point literals

[Greg Kroah-Hartman]

From: Nathan Chancellor <nathan@kernel.org>

commit 644106cdb89844be2496b21175b7c0c2e0fab381 upstream.

A new commit in LLVM causes an error on the use of 'long double' when
'-mno-x87' is used, which the kernel does through an alias,
'-mno-80387' (see the LLVM commit below for more details around why it
does this).

drivers/power/reset/ltc2952-poweroff.c:162:28: error: expression requires  'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it
        data->wde_interval = 300L * 1E6L;
                                  ^
drivers/power/reset/ltc2952-poweroff.c:162:21: error: expression requires  'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it
        data->wde_interval = 300L * 1E6L;
                           ^
drivers/power/reset/ltc2952-poweroff.c:163:41: error: expression requires  'long double' type support, but target 'x86_64-unknown-linux-gnu' does not support it
        data->trigger_delay = ktime_set(2, 500L*1E6L);
                                               ^
3 errors generated.

This happens due to the use of a 'long double' literal. The 'E6' part of
'1E6L' causes the literal to be a 'double' then the 'L' suffix promotes
it to 'long double'.

There is no visible reason for floating point values in this driver, as
the values are only assigned to integer types. Use NSEC_PER_MSEC, which
is the same integer value as '1E6L', to avoid changing functionality but
fix the error.

[PATCH 4.14 15/22] rndis_host: support Hytera digital radios

[Greg Kroah-Hartman]

From: Thomas Toye <thomas@toye.io>

commit 29262e1f773b4b6a43711120be564c57fca07cfb upstream.

Hytera makes a range of digital (DMR) radios. These radios can be
programmed to a allow a computer to control them over Ethernet over USB,
either using NCM or RNDIS.

This commit adds support for RNDIS for Hytera radios. I tested with a
Hytera PD785 and a Hytera MD785G. When these radios are programmed to
set up a Radio to PC Network using RNDIS, an USB interface will be added
with class 2 (Communications), subclass 2 (Abstract Modem Control) and
an interface protocol of 255 ("vendor specific" - lsusb even hints "MSFT
RNDIS?").

This patch is similar to the solution of this StackOverflow user, but
that only works for the Hytera MD785:
https://stackoverflow.com/a/53550858

To use the "Radio to PC Network" functionality of Hytera DMR radios, the
radios need to be programmed correctly in CPS (Hytera's Customer
Programming Software). "Forward to PC" should be checked in "Network"
(under "General Setting" in "Conventional") and the "USB Network
Communication Protocol" should be set to RNDIS.

[PATCH 4.14 20/22] ip6_vti: initialize __ip6_tnl_parm struct in vti6_siocdevprivate

[Greg Kroah-Hartman]

From: William Zhao <wizhao@redhat.com>

[ Upstream commit c1833c3964d5bd8c163bd4e01736a38bc473cb8a ]

The "__ip6_tnl_parm" struct was left uninitialized causing an invalid
load of random data when the "__ip6_tnl_parm" struct was used elsewhere.
As an example, in the function "ip6_tnl_xmit_ctl()", it tries to access
the "collect_md" member. With "__ip6_tnl_parm" being uninitialized and
containing random data, the UBSAN detected that "collect_md" held a
non-boolean value.

The UBSAN issue is as follows:

[PATCH 4.14 22/22] mISDN: change function names to avoid conflicts

[Greg Kroah-Hartman]

From: wolfgang huang <huangjinhui@kylinos.cn>

[ Upstream commit 8b5fdfc57cc2471179d1c51081424ded833c16c8 ]

As we build for mips, we meet following error. l1_init error with
multiple definition. Some architecture devices usually marked with
l1, l2, lxx as the start-up phase. so we change the mISDN function
names, align with Isdnl2_xxx.

mips-linux-gnu-ld: drivers/isdn/mISDN/layer1.o: in function `l1_init':
(.text+0x890): multiple definition of `l1_init'; \
arch/mips/kernel/bmips_5xxx_init.o:(.text+0xf0): first defined here
make[1]: *** [home/mips/kernel-build/linux/Makefile:1161: vmlinux] Error 1
