[ Upstream commit 17d51b10d7 ]
bio_iov_iter_get_pages() currently only adds pages for the next non-zero
segment from the iov_iter to the bio. That's suboptimal for callers,
which typically try to pin as many pages as fit into the bio. This patch
converts the current bio_iov_iter_get_pages() into a static helper, and
introduces a new helper that allocates as many pages as
1) fit into the bio,
2) are present in the iov_iter,
3) and can be pinned by MM.
Error is returned only if zero pages could be pinned. Because of 3), a
zero return value doesn't necessarily mean all pages have been pinned.
Callers that have to pin every page in the iov_iter must still call this
function in a loop (this is currently the case).
This change matters most for __blkdev_direct_IO_simple(), which calls
bio_iov_iter_get_pages() only once. If it obtains less pages than
requested, it returns a "short write" or "short read", and
__generic_file_write_iter() falls back to buffered writes, which may
lead to data corruption.

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.

commit 79c92ca42b 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.

commit 693cd8ce3f 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.

commit 88a748419b 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).

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.

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.

[ Upstream commit 335726195e ]
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.

[ Upstream commit 1c81073909 ]
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.

[ Upstream commit b96151edce ]
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.

[ Upstream commit 56cd0aefa4 ]
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 3581fe0ef3 ("ARM: 7556/1: perf: fix updated event period in
response to PERF_EVENT_IOC_PERIOD") for details.

In get_vdev_port_node_info(), 'node_info->vdev_port.name' is allcoated
by kstrdup_const(), and it returns NULL when fails. So
'node_info->vdev_port.name' should be checked.

[ Upstream commit 62394708f3 ]
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.

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

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

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.
