[PATCH 4.14 01/51] tracing: Silence GCC 9 array bounds warning

[Greg Kroah-Hartman]

From: Miguel Ojeda <miguel.ojeda.sandonis@gmail.com>

commit 0c97bf863efce63d6ab7971dad811601e6171d2f upstream.

Starting with GCC 9, -Warray-bounds detects cases when memset is called
starting on a member of a struct but the size to be cleared ends up
writing over further members.

Such a call happens in the trace code to clear, at once, all members
after and including `seq` on struct trace_iterator:

    In function 'memset',
        inlined from 'ftrace_dump' at kernel/trace/trace.c:8914:3:
    ./include/linux/string.h:344:9: warning: '__builtin_memset' offset
    [8505, 8560] from the object at 'iter' is out of the bounds of
    referenced subobject 'seq' with type 'struct trace_seq' at offset
    4368 [-Warray-bounds]
      344 |  return __builtin_memset(p, c, size);
          |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

In order to avoid GCC complaining about it, we compute the address
ourselves by adding the offsetof distance instead of referring
directly to the member.

Since there are two places doing this clear (trace.c and trace_kdb.c),
take the chance to move the workaround into a single place in
the internal header.

[PATCH 4.14 02/51] objtool: Support per-function rodata sections

[Greg Kroah-Hartman]

From: Allan Xavier <allan.x.xavier@oracle.com>

commit 4a60aa05a0634241ce17f957bf9fb5ac1eed6576 upstream.

Add support for processing switch jump tables in objects with multiple
.rodata sections, such as those created by '-ffunction-sections' and
'-fdata-sections'.  Currently, objtool always looks in .rodata for jump
table information, which results in many "sibling call from callable
instruction with modified stack frame" warnings with objects compiled
using those flags.

The fix is comprised of three parts:

1. Flagging all .rodata sections when importing ELF information for
   easier checking later.

2. Keeping a reference to the section each relocation is from in order
   to get the list_head for the other relocations in that section.

3. Finding jump tables by following relocations to .rodata sections,
   rather than always referencing a single global .rodata section.

The patch has been tested without data sections enabled and no
differences in the resulting orc unwind information were seen.

Note that as objtool adds terminators to end of each .text section the
unwind information generated between a function+data sections build and
a normal build aren't directly comparable. Manual inspection suggests
that objtool is now generating the correct information, or at least
making more of an effort to do so than it did previously.

[PATCH 4.14 03/51] gcc-9: silence address-of-packed-member warning

[Greg Kroah-Hartman]

From: Linus Torvalds <torvalds@linux-foundation.org>

commit 6f303d60534c46aa1a239f29c321f95c83dda748 upstream.

We already did this for clang, but now gcc has that warning too.  Yes,
yes, the address may be unaligned.  And that's kind of the point.

[PATCH 4.14 04/51] net: phy: broadcom: Use strlcpy() for ethtool::get_strings

[Greg Kroah-Hartman]

From: Florian Fainelli <f.fainelli@gmail.com>

commit 8a17eefa235f73b60c0ca7d397d2e4f66f85f413 upstream.

Our statistics strings are allocated at initialization without being
bound to a specific size, yet, we would copy ETH_GSTRING_LEN bytes using
memcpy() which would create out of bounds accesses, this was flagged by
KASAN. Replace this with strlcpy() to make sure we are bound the source
buffer size and we also always NUL-terminate strings.

[PATCH 4.14 05/51] mmc: core: Prevent processing SDIO IRQs when the card is suspended

[Greg Kroah-Hartman]

From: Ulf Hansson <ulf.hansson@linaro.org>

commit 83293386bc95cf5e9f0c0175794455835bd1cb4a upstream.

Processing of SDIO IRQs must obviously be prevented while the card is
system suspended, otherwise we may end up trying to communicate with an
uninitialized SDIO card.

Reports throughout the years shows that this is not only a theoretical
problem, but a real issue. So, let's finally fix this problem, by keeping
track of the state for the card and bail out before processing the SDIO
IRQ, in case the card is suspended.

[PATCH 4.14 06/51] scsi: ufs: Avoid runtime suspend possibly being blocked forever

[Greg Kroah-Hartman]

From: Stanley Chu <stanley.chu@mediatek.com>

commit 24e2e7a19f7e4b83d0d5189040d997bce3596473 upstream.

UFS runtime suspend can be triggered after pm_runtime_enable() is invoked
in ufshcd_pltfrm_init(). However if the first runtime suspend is triggered
before binding ufs_hba structure to ufs device structure via
platform_set_drvdata(), then UFS runtime suspend will be no longer
triggered in the future because its dev->power.runtime_error was set in the
first triggering and does not have any chance to be cleared.

To be more clear, dev->power.runtime_error is set if hba is NULL in
ufshcd_runtime_suspend() which returns -EINVAL to rpm_callback() where
dev->power.runtime_error is set as -EINVAL. In this case, any future
rpm_suspend() for UFS device fails because rpm_check_suspend_allowed()
fails due to non-zero
dev->power.runtime_error.

To resolve this issue, make sure the first UFS runtime suspend get valid
"hba" in ufshcd_runtime_suspend(): Enable UFS runtime PM only after hba is
successfully bound to UFS device structure.

[PATCH 4.14 07/51] usb: chipidea: udc: workaround for endpoint conflict issue

[Greg Kroah-Hartman]

From: Peter Chen <peter.chen@nxp.com>

commit c19dffc0a9511a7d7493ec21019aefd97e9a111b upstream.

An endpoint conflict occurs when the USB is working in device mode
during an isochronous communication. When the endpointA IN direction
is an isochronous IN endpoint, and the host sends an IN token to
endpointA on another device, then the OUT transaction may be missed
regardless the OUT endpoint number. Generally, this occurs when the
device is connected to the host through a hub and other devices are
connected to the same hub.

The affected OUT endpoint can be either control, bulk, isochronous, or
an interrupt endpoint. After the OUT endpoint is primed, if an IN token
to the same endpoint number on another device is received, then the OUT
endpoint may be unprimed (cannot be detected by software), which causes
this endpoint to no longer respond to the host OUT token, and thus, no
corresponding interrupt occurs.

There is no good workaround for this issue, the only thing the software
could do is numbering isochronous IN from the highest endpoint since we
have observed most of device number endpoint from the lowest.

The shortage is handled properly so the message isn't needed. Silence by
adding the no warn option to the slab allocation.

In the case of compat syscall ioctl numbers for UI_BEGIN_FF_UPLOAD and
UI_END_FF_UPLOAD need to be adjusted before being passed on
uinput_ioctl_handler() since code built with -m32 will be passing

[PATCH 4.14 11/51] apparmor: enforce nullbyte at end of tag string

[Greg Kroah-Hartman]

From: Jann Horn <jannh@google.com>

commit 8404d7a674c49278607d19726e0acc0cae299357 upstream.

A packed AppArmor policy contains null-terminated tag strings that are read
by unpack_nameX(). However, unpack_nameX() uses string functions on them
without ensuring that they are actually null-terminated, potentially
leading to out-of-bounds accesses.

Make sure that the tag string is null-terminated before passing it to
strcmp().

[PATCH 4.14 13/51] ARC: [plat-hsdk]: Add missing multicast filter bins number to GMAC node

[Greg Kroah-Hartman]

[ Upstream commit ecc906a11c2a0940e1a380debd8bd5bc09faf454 ]

GMAC controller on HSDK boards supports 256 Hash Table size so we need to
add the multicast filter bins property. This allows for the Hash filter
to work properly using stmmac driver.

[PATCH 4.14 17/51] IB/rdmavt: Fix alloc_qpn() WARN_ON()

[Greg Kroah-Hartman]

[ Upstream commit 2abae62a26a265129b364d8c1ef3be55e2c01309 ]

The qpn allocation logic has a WARN_ON() that intends to detect the use of
an index that will introduce bits in the lower order bits of the QOS bits
in the QPN.

Unfortunately, it has the following bugs:
- it misfires when wrapping QPN allocation for non-QOS
- it doesn't correctly detect low order QOS bits (despite the comment)

The WARN_ON() should not be applied to non-QOS (qos_shift == 1).

Additionally, it SHOULD test the qpn bits per the table below:

2 data VLs:   [qp7, qp6, qp5, qp4, qp3, qp2, qp1] ^
              [  0,   0,   0,   0,   0,   0, sc0],  qp bit 1 always 0*
3-4 data VLs: [qp7, qp6, qp5, qp4, qp3, qp2, qp1] ^
              [  0,   0,   0,   0,   0, sc1, sc0], qp bits [21] always 0
5-8 data VLs: [qp7, qp6, qp5, qp4, qp3, qp2, qp1] ^
              [  0,   0,   0,   0, sc2, sc1, sc0] qp bits [321] always 0

Fix by qualifying the warning for qos_shift > 1 and producing the correct
mask to insure the above bits are zero without generating a superfluous
warning.

[PATCH 4.14 20/51] IB/hfi1: Validate page aligned for a given virtual address

[Greg Kroah-Hartman]

[ Upstream commit 97736f36dbebf2cda2799db3b54717ba5b388255 ]

User applications can register memory regions for TID buffers that are not
aligned on page boundaries. Hfi1 is expected to pin those pages in memory
and cache the pages with mmu_rb. The rb tree will fail to insert pages
that are not aligned correctly.

Validate whether a given virtual address is page aligned before pinning.

Fixes: 7e7a436ecb6e ("staging/hfi1: Add TID entry program function body")

Since commit 9012d011660ea5cf2 ("compiler: allow all arches to enable
CONFIG_OPTIMIZE_INLINING"), xtensa:tinyconfig fails to build with section
mismatch errors.

WARNING: vmlinux.o(.text.unlikely+0x68): Section mismatch in reference

	to the function .meminit.text:memblock_reserve()
FATAL: modpost: Section mismatches detected.

This was not seen prior to the above mentioned commit because mem_reserve()
was always inlined.

Mark mem_reserve(() as __init_memblock to have it reside in the same
section as memblock_reserve().

[PATCH 4.14 23/51] net: dsa: mv88e6xxx: avoid error message on remove from VLAN 0

[Greg Kroah-Hartman]

[ Upstream commit 62394708f3e01c9f2be6be74eb6305bae1ed924f ]

When non-bridged, non-vlan'ed mv88e6xxx port is moving down, error
message is logged:

failed to kill vid 0081/0 for device eth_cu_1000_4

This is caused by call from __vlan_vid_del() with vin set to zero, over
call chain this results into _mv88e6xxx_port_vlan_del() called with
vid=0, and mv88e6xxx_vtu_get() called from there returns -EINVAL.

On symmetric path moving port up, call goes through
mv88e6xxx_port_vlan_prepare() that calls mv88e6xxx_port_check_hw_vlan()
that returns -EOPNOTSUPP for zero vid.

This patch changes mv88e6xxx_vtu_get() to also return -EOPNOTSUPP for
zero vid, then this error code is explicitly cleared in
dsa_slave_vlan_rx_kill_vid() and error message is no longer logged.

[PATCH 4.14 26/51] sparc: perf: fix updated event period in response to PERF_EVENT_IOC_PERIOD

[Greg Kroah-Hartman]

[ Upstream commit 56cd0aefa475079e9613085b14a0f05037518fed ]

The PERF_EVENT_IOC_PERIOD ioctl command can be used to change the
sample period of a running perf_event. Consequently, when calculating
the next event period, the new period will only be considered after the
previous one has overflowed.

This patch changes the calculation of the remaining event ticks so that
they are offset if the period has changed.

See commit 3581fe0ef37c ("ARM: 7556/1: perf: fix updated event period in
response to PERF_EVENT_IOC_PERIOD") for details.

[Greg Kroah-Hartman]

[ Upstream commit b96151edced4edb6a18aa89a5fa02c7066efff45 ]

Rather than allowing any old mode through, then subsequently refusing
unmatchable clock rates in atomic_check when it's too late to back out
and pick a different mode, let's do that validation up-front where it
will cause unsupported modes to be correctly pruned in the first place.

This also eliminates an issue whereby a perceived clock rate of 0 would
cause atomic disable to fail and prevent the module from being unloaded.

[PATCH 4.14 30/51] drm/arm/hdlcd: Allow a bit of clock tolerance

[Greg Kroah-Hartman]

[ Upstream commit 1c810739097fdeb31b393b67a0a1e3d7ffdd9f63 ]

On the Arm Juno platform, the HDLCD pixel clock is constrained to 250KHz
resolution in order to avoid the tiny System Control Processor spending
aeons trying to calculate exact PLL coefficients. This means that modes
like my oddball 1600x1200 with 130.89MHz clock get rejected since the
rate cannot be matched exactly. In practice, though, this mode works
quite happily with the clock at 131MHz, so let's relax the check to
allow a little bit of slop.

[PATCH 4.14 32/51] scsi: ufs: Check that space was properly alloced in copy_query_response

[Greg Kroah-Hartman]

[ Upstream commit 1c90836f70f9a8ef7b7ad9e1fdd8961903e6ced6 ]

struct ufs_dev_cmd is the main container that supports device management
commands. In the case of a read descriptor request, we assume that the
proper space was allocated in dev_cmd to hold the returning descriptor.

This is no longer true, as there are flows that doesn't use dev_cmd for
device management requests, and was wrong in the first place.

[PATCH 4.14 34/51] net: ipvlan: Fix ipvlan device tso disabled while NETIF_F_IP_CSUM is set

[Greg Kroah-Hartman]

[ Upstream commit ceae266bf0ae6564ac16d086bf749a096fa90ded ]

There's some NICs, such as hinic, with NETIF_F_IP_CSUM and NETIF_F_TSO
on but NETIF_F_HW_CSUM off. And ipvlan device features will be
NETIF_F_TSO on with NETIF_F_IP_CSUM and NETIF_F_IP_CSUM both off as
IPVLAN_FEATURES only care about NETIF_F_HW_CSUM. So TSO will be
disabled in netdev_fix_features.
For example:
Features for enp129s0f0:
rx-checksumming: on
tx-checksumming: on
        tx-checksum-ipv4: on
        tx-checksum-ip-generic: off [fixed]

[PATCH 4.14 35/51] s390/qeth: fix VLAN attribute in bridge_hostnotify udev event

[Greg Kroah-Hartman]

[ Upstream commit 335726195e460cb6b3f795b695bfd31f0ea70ef0 ]

Enabling sysfs attribute bridge_hostnotify triggers a series of udev events
for the MAC addresses of all currently connected peers. In case no VLAN is
set for a peer, the device reports the corresponding MAC addresses with
VLAN ID 4096. This currently results in attribute VLAN=4096 for all
non-VLAN interfaces in the initial series of events after host-notify is
enabled.

Instead, no VLAN attribute should be reported in the udev event for
non-VLAN interfaces.

Only the initial events face this issue. For dynamic changes that are
reported later, the device uses a validity flag.

This also changes the code so that it now sets the VLAN attribute for
MAC addresses with VID 0. On Linux, no qeth interface will ever be
registered with VID 0: Linux kernel registers VID 0 on all network
interfaces initially, but qeth will drop .ndo_vlan_rx_add_vid for VID 0.
Peers with other OSs could register MACs with VID 0.

[PATCH 4.14 36/51] hwmon: (core) add thermal sensors only if dev->of_node is present

[Greg Kroah-Hartman]

[ Upstream commit c41dd48e21fae3e55b3670ccf2eb562fc1f6a67d ]

Drivers may register to hwmon and request for also registering
with the thermal subsystem (HWMON_C_REGISTER_TZ). However,
some of these driver, e.g. marvell phy, may be probed from
Device Tree or being dynamically allocated, and in the later
case, it will not have a dev->of_node entry.

Registering with hwmon without the dev->of_node may result in
different outcomes depending on the device tree, which may
be a bit misleading. If the device tree blob has no 'thermal-zones'
node, the *hwmon_device_register*() family functions are going
to gracefully succeed, because of-thermal,
*thermal_zone_of_sensor_register() return -ENODEV in this case,
and the hwmon error path handles this error code as success to
cover for the case where CONFIG_THERMAL_OF is not set.
However, if the device tree blob has the 'thermal-zones'
entry, the *hwmon_device_register*() will always fail on callers
with no dev->of_node, propagating -EINVAL.

If dev->of_node is not present, calling of-thermal does not
make sense. For this reason, this patch checks first if the
device has a of_node before going over the process of registering
with the thermal subsystem of-thermal interface. And in this case,
when a caller of *hwmon_device_register*() with HWMON_C_REGISTER_TZ
and no dev->of_node will still register with hwmon, but not with
the thermal subsystem. If all the hwmon part bits are in place,
the registration will succeed.

[PATCH 4.14 37/51] hwmon: (pmbus/core) Treat parameters as paged if on multiple pages

[Greg Kroah-Hartman]

[ Upstream commit 4a60570dce658e3f8885bbcf852430b99f65aca5 ]

Some chips have attributes which exist on more than one page but the
attribute is not presently marked as paged. This causes the attributes
to be generated with the same label, which makes it impossible for
userspace to tell them apart.

Marking all such attributes as paged would result in the page suffix
being added regardless of whether they were present on more than one
page or not, which might break existing setups. Therefore, we add a
second check which treats the attribute as paged, even if not marked as
such, if it is present on multiple pages.

Currently, btrfs does not consult seed devices to start readahead. As a
result, if readahead zone is added to the seed devices, btrfs_reada_wait()
indefinitely wait for the reada_ctl to finish.

You can reproduce the hung by modifying btrfs/163 to have larger initial
file size (e.g. xfs_io pwrite 4M instead of current 256K).

[PATCH 4.14 40/51] can: flexcan: fix timeout when set small bitrate

[Greg Kroah-Hartman]

From: Joakim Zhang <qiangqing.zhang@nxp.com>

commit 247e5356a709eb49a0d95ff2a7f07dac05c8252c upstream.

Current we can meet timeout issue when setting a small bitrate like
10000 as follows on i.MX6UL EVK board (ipg clock = 66MHZ, per clock =
30MHZ):

| root@imx6ul7d:~# ip link set can0 up type can bitrate 10000

A link change request failed with some changes committed already.
Interface can0 may have been left with an inconsistent configuration,
please check.

| RTNETLINK answers: Connection timed out

It is caused by calling of flexcan_chip_unfreeze() timeout.

Originally the code is using usleep_range(10, 20) for unfreeze
operation, but the patch (8badd65 can: flexcan: avoid calling
usleep_range from interrupt context) changed it into udelay(10) which is
only a half delay of before, there're also some other delay changes.

After double to FLEXCAN_TIMEOUT_US to 100 can fix the issue.

Meanwhile, Rasmus Villemoes reported that even with a timeout of 100,
flexcan_probe() fails on the MPC8309, which requires a value of at least
140 to work reliably. 250 works for everyone.

[PATCH 4.14 43/51] ARM: imx: cpuidle-imx6sx: Restrict the SW2ISO increase to i.MX6SX

[Greg Kroah-Hartman]

From: Fabio Estevam <festevam@gmail.com>

commit b25af2ff7c07bd19af74e3f64ff82e2880d13d81 upstream.

Since commit 1e434b703248 ("ARM: imx: update the cpu power up timing
setting on i.mx6sx") some characters loss is noticed on i.MX6ULL UART
as reported by Christoph Niedermaier.

The intention of such commit was to increase the SW2ISO field for i.MX6SX
only, but since cpuidle-imx6sx is also used on i.MX6UL/i.MX6ULL this caused
unintended side effects on other SoCs.

Fix this problem by keeping the original SW2ISO value for i.MX6UL/i.MX6ULL
and only increase SW2ISO in the i.MX6SX case.

[PATCH 4.14 44/51] ARM: dts: am57xx-idk: Remove support for voltage switching for SD card

[Greg Kroah-Hartman]

From: Faiz Abbas <faiz_abbas@ti.com>

commit 88a748419b84187fd1da05637b8e5928b04a1e06 upstream.

If UHS speed modes are enabled, a compatible SD card switches down to
1.8V during enumeration. If after this a software reboot/crash takes
place and on-chip ROM tries to enumerate the SD card, the difference in
IO voltages (host @ 3.3V and card @ 1.8V) may end up damaging the card.

The fix for this is to have support for power cycling the card in
hardware (with a PORz/soft-reset line causing a power cycle of the
card). Since am571x-, am572x- and am574x-idk don't have this
capability, disable voltage switching for these boards.

The major effect of this is that the maximum supported speed
mode is now high speed(50 MHz) down from SDR104(200 MHz).

[PATCH 4.14 46/51] Bluetooth: Fix regression with minimum encryption key size alignment

[Greg Kroah-Hartman]

From: Marcel Holtmann <marcel@holtmann.org>

commit 693cd8ce3f882524a5d06f7800dd8492411877b3 upstream.

When trying to align the minimum encryption key size requirement for
Bluetooth connections, it turns out doing this in a central location in
the HCI connection handling code is not possible.

Original Bluetooth version up to 2.0 used a security model where the
L2CAP service would enforce authentication and encryption.  Starting
with Bluetooth 2.1 and Secure Simple Pairing that model has changed into
that the connection initiator is responsible for providing an encrypted
ACL link before any L2CAP communication can happen.

Now connecting Bluetooth 2.1 or later devices with Bluetooth 2.0 and
before devices are causing a regression.  The encryption key size check
needs to be moved out of the HCI connection handling into the L2CAP
channel setup.

To achieve this, the current check inside hci_conn_security() has been
moved into l2cap_check_enc_key_size() helper function and then called
from four decisions point inside L2CAP to cover all combinations of
Secure Simple Pairing enabled devices and device using legacy pairing
and legacy service security model.

[PATCH 4.14 47/51] SMB3: retry on STATUS_INSUFFICIENT_RESOURCES instead of failing write

[Greg Kroah-Hartman]

From: Steve French <stfrench@microsoft.com>

commit 8d526d62db907e786fd88948c75d1833d82bd80e upstream.

Some servers such as Windows 10 will return STATUS_INSUFFICIENT_RESOURCES
as the number of simultaneous SMB3 requests grows (even though the client
has sufficient credits).  Return EAGAIN on STATUS_INSUFFICIENT_RESOURCES
so that we can retry writes which fail with this status code.

This (for example) fixes large file copies to Windows 10 on fast networks.

[PATCH 4.14 50/51] mac80211: handle deauthentication/disassociation from TDLS peer

[Greg Kroah-Hartman]

From: Yu Wang <yyuwang@codeaurora.org>

commit 79c92ca42b5a3e0ea172ea2ce8df8e125af237da upstream.

When receiving a deauthentication/disassociation frame from a TDLS
peer, a station should not disconnect the current AP, but only
disable the current TDLS link if it's enabled.

Without this change, a TDLS issue can be reproduced by following the
steps as below:

1. STA-1 and STA-2 are connected to AP, bidirection traffic is running
   between STA-1 and STA-2.
2. Set up TDLS link between STA-1 and STA-2, stay for a while, then
   teardown TDLS link.
3. Repeat step #2 and monitor the connection between STA and AP.

During the test, one STA may send a deauthentication/disassociation
frame to another, after TDLS teardown, with reason code 6/7, which
means: Class 2/3 frame received from nonassociated STA.

On receive this frame, the receiver STA will disconnect the current
AP and then reconnect. It's not a expected behavior, purpose of this
frame should be disabling the TDLS link, not the link with AP.

[PATCH 4.14 51/51] mac80211: Do not use stack memory with scatterlist for GMAC

[Greg Kroah-Hartman]

From: Jouni Malinen <j@w1.fi>

commit a71fd9dac23613d96ba3c05619a8ef4fd6cdf9b9 upstream.

ieee80211_aes_gmac() uses the mic argument directly in sg_set_buf() and
that does not allow use of stack memory (e.g., BUG_ON() is hit in
sg_set_buf() with CONFIG_DEBUG_SG). BIP GMAC TX side is fine for this
since it can use the skb data buffer, but the RX side was using a stack
variable for deriving the local MIC value to compare against the
received one.

Fix this by allocating heap memory for the mic buffer.

This was found with hwsim test case ap_cipher_bip_gmac_128 hitting that
BUG_ON() and kernel panic.
