[ Upstream commit 1dbdd99b511c966be9147ad72991a2856ac76f22 ]
While debugging an issue we've found that $DEBUGFS/block/$disk/state
doesn't decode QUEUE_FLAG_HCTX_ACTIVE but only displays its numerical
value.
Add QUEUE_FLAG(HCTX_ACTIVE) to the blk_queue_flag_name array so it'll get
decoded properly.

[ Upstream commit 4348cc10da6377a86940beb20ad357933b8f91bb ]
Without a sensor node, the ISC will simply fail to probe, as the
corresponding port node is missing.
It is then logical to disable the node in the devicetree.
If we add a port with a connection to a sensor endpoint, ISC can be enabled.

Seen on a VLI VL805 PCIe to USB controller. For non-stream endpoints
at least, if the xHC halts on a particular TRB due to an error then
the DCS field in the Out Endpoint Context maintained by the hardware
is not updated with the current cycle state.
Using the quirk XHCI_EP_CTX_BROKEN_DCS and instead fetch the DCS bit
from the TRB that the xHC stopped on.

commit 4a3e0aeddf091f00974b02627c157843ce382a24 upstream.
mv88e6xxx_port_ppu_updates() interpretes data in the PORT_STS
register incorrectly for internal ports (ie no PPU). In these
cases, the PHY_DETECT bit indicates link status. This results
in forcing the MAC state whenever the PHY link goes down which
is not intended. As a side effect, LED's configured to show
link status stay lit even though the physical link is down.
Add a check in mac_link_down and mac_link_up to see if it
concerns an external port and only then, look at PPU status.

commit 5c976a56570f29aaf4a2f9a1bf99789c252183c9 upstream.
Bridging, and possibly other upper stack gizmos, adds the
lower device's netdev->dev_addr to its own uc list, and
then requests it be deleted when the upper bridge device is
removed. This delete request also happens with the bridging
vlan_filtering is enabled and then disabled.
Bonding has a similar behavior with the uc list, but since it
also uses set_mac to manage netdev->dev_addr, it doesn't have
the same the failure case.
Because we store our netdev->dev_addr in our uc list, we need
to ignore the delete request from dev_uc_sync so as to not
lose the address and all hope of communicating. Note that
ndo_set_mac_address is expressly changing netdev->dev_addr,
so no limitation is set there.

commit 9fde506e0c53b8309f69b18b4b8144c544b4b3b1 upstream.
When skb_match is NULL, it means we received a PTP IRQ for a timestamp
ID that the kernel has no idea about, since there is no skb in the
timestamping queue with that timestamp ID.
This is a grave error and not something to just "continue" over.
So print a big warning in case this happens.
Also, move the check above ocelot_get_hwtimestamp(), there is no point
in reading the full 64-bit current PTP time if we're not going to do
anything with it anyway for this skb.

commit 14132690860e4d06aa3e1c4d7d8e9866ba7756dd upstream.
Introduction of lockless subqueues broke the class statistics.
Before the change stats were accumulated in `bstats' and `qstats'
on the stack which was then copied to struct gnet_dump.
After the change the `bstats' and `qstats' are initialized to 0
and never updated, yet still fed to gnet_dump. The code updates
the global qdisc->cpu_bstats and qdisc->cpu_qstats instead,
clobbering them. Most likely a copy-paste error from the code in
mqprio_dump().
__gnet_stats_copy_basic() and __gnet_stats_copy_queue() accumulate
the values for per-CPU case but for global stats they overwrite
the value, so only stats from the last loop iteration / tc end up
in sch->[bq]stats.
Use the on-stack [bq]stats variables again and add the stats manually
in the global case.

In commit e11f5bd8228f ("drm: Add support for DP 1.4 Compliance edid
corruption test") the function connector_bad_edid() started assuming
that the memory for the EDID passed to it was big enough to hold
`edid[0x7e] + 1` blocks of data (1 extra for the base block). It
completely ignored the fact that the function was passed `num_blocks`
which indicated how much memory had been allocated for the EDID.
Let's fix this by adding a bounds check.
This is important for handling the case where there's an error in the
first block of the EDID. In that case we will call
connector_bad_edid() without having re-allocated memory based on
`edid[0x7e]`.

commit 9b024201693e397441668cca0d2df7055fe572eb upstream.
Change kstrtou32() argument 'base' to be zero instead of 'len'.
It works by chance for setting one bit value, but it is not supposed to
work in case value passed to mlxreg_io_attr_store() is greater than 1.
It works for example, for:
echo 1 > /sys/devices/platform/mlxplat/mlxreg-io/hwmon/.../jtag_enable
But it will fail for:
echo n > /sys/devices/platform/mlxplat/mlxreg-io/hwmon/.../jtag_enable,
where n > 1.
The flow for input buffer conversion is as below:
_kstrtoull(const char *s, unsigned int base, unsigned long long *res)
calls:
rv = _parse_integer(s, base, &_res);
For the second case, where n > 1:
- _parse_integer() converts 's' to 'val'.
For n=2, 'len' is set to 2 (string buffer is 0x32 0x0a), for n=3
'len' is set to 3 (string buffer 0x33 0x0a), etcetera.
- 'base' is equal or greater then '2' (length of input buffer).
As a result, _parse_integer() exits with result zero (rv):
rv = 0;
while (1) {
...
if (val >= base)-> (2 >= 2)
break;
...
rv++;
...
}
And _kstrtoull() in their turn will fail:
if (rv == 0)
return -EINVAL;

commit 332fdf951df8b870e3da86b122ae304e2aabe88c upstream.
Currently, mlxsw allows cooling states to be set above the maximum
cooling state supported by the driver:
# cat /sys/class/thermal/thermal_zone2/cdev0/type
mlxsw_fan
# cat /sys/class/thermal/thermal_zone2/cdev0/max_state
10
# echo 18 > /sys/class/thermal/thermal_zone2/cdev0/cur_state
# echo $?
0
This results in out-of-bounds memory accesses when thermal state
transition statistics are enabled (CONFIG_THERMAL_STATISTICS=y), as the
transition table is accessed with a too large index (state) [1].
According to the thermal maintainer, it is the responsibility of the
driver to reject such operations [2].
Therefore, return an error when the state to be set exceeds the maximum
cooling state supported by the driver.
To avoid dead code, as suggested by the thermal maintainer [3],
partially revert commit a421ce088ac8 ("mlxsw: core: Extend cooling
device with cooling levels") that tried to interpret these invalid
cooling states (above the maximum) in a special way. The cooling levels
array is not removed in order to prevent the fans going below 20% PWM,
which would cause them to get stuck at 0% PWM.

After recent cleanups, gcc started warning about a suspicious

include/linux/netdevice.h:4648:9: note: in expansion of macro 'memcpy'

What apparently happened is that an old cleanup changed the calling
conventions for s2io_set_mac_addr() from taking an ethernet address
as a character array to taking a struct sockaddr, but one of the
callers was not changed at the same time.
Change it to instead call the low-level do_s2io_prog_unicast() function
that still takes the old argument type.

commit ef1100ef20f29aec4e62abeccdb5bdbebba1e378 upstream.
When the ksz module is installed and removed using rmmod, kernel crashes
with null pointer dereferrence error. During rmmod, ksz_switch_remove
function tries to cancel the mib_read_workqueue using
cancel_delayed_work_sync routine and unregister switch from dsa.
During dsa_unregister_switch it calls ksz_mac_link_down, which in turn
reschedules the workqueue since mib_interval is non-zero.
Due to which queue executed after mib_interval and it tries to access
dp->slave. But the slave is unregistered in the ksz_switch_remove
function. Hence kernel crashes.
To avoid this crash, before canceling the workqueue, resetted the
mib_interval to 0.
v1 -> v2:
-Removed the if condition in ksz_mib_read_work

commit 075da584bae2da6a37428d59a477b6bdad430ac3 upstream.
Some old IPs do not provide the hardware feature register.
On these IPs, this register is read 0x00000000.
In old driver version, this feature was handled but a regression came
with the commit f10a6a3541b4 ("stmmac: rework get_hw_feature function").
Indeed, this commit removes the return value in dma->get_hw_feature().
This return value was used to indicate the validity of retrieved
information and used later on in stmmac_hw_init() to override
priv->plat data if this hardware feature were valid.
This patch restores the return code in ->get_hw_feature() in order
to indicate the hardware feature validity and override priv->plat
data only if this hardware feature is valid.

The commit 15add06841a3 ("gpio: pca953x: add ->set_config implementation")
introduced support for bias setting. However this, due to being half-baked,
brought potential issues:
- the turning bias via disabling makes the pin floating for a while;
- once enabled, bias can't be disabled.
Fix all these by adding support for bias disabling and move the disabling
part under the corresponding conditional.
While at it, add support for default setting, since it's cheap to add.
