commit dcd01394ce7cd7d25bb15c81ad2e804d8090611f upstream
In general, "pvt->umc != NULL" is used to check if the system is Family
17h+. However, there are a few places that are using direct family
checks.
Replace the remaining family checks with a check for "pvt->umc != NULL".

Add Altra LED driver to control NVME LED.
This driver support control LED via SPCI interface on Altra system.
Currently, it is 2-LEDs system(Activity LED, Status LED). Activity
LED is completely controlled by hardware. Status LED is controlled
by this driver.
There are 4 stages of Status LED:
- ON
- OFF
- Locate(blink at 1Hz)
- Rebuild(blink at 4Hz)
Example:
To On, Off the LED on slot 9:
1. Write the seg:bus_number corresponding to LED on slot 9 to
altra:led
echo 000b:03 > /sys/class/leds/altra:led/address
2. Write 1 to brightness attr to ON, 0 to brightness attr to OFF
echo 1 > /sys/class/leds/altra:led/brightness
echo 0 > /sys/class/leds/altra:led/brightness
To blink the LED on slot 9:
1. Write the seg:bus_number corresponding to LED on slot 9 to
altra:led
echo 000b:03 > /sys/class/leds/altra:led/address
2. Write 1 to blink attr to select Locate(blink 1Hz), or 4 to
blink attr to select Rebuild(blink 4Hz)
echo 1 > /sys/class/leds/altra:led/blink
echo 4 > /sys/class/leds/altra:led/blink
3. Write 1 to shot attr to execute blink
echo 1 > /sys/class/leds/altra:led/shot

When the master tries to send data to the slave that has gone offline, the
transmission gets stuck. Even when a slave returns back online, the bus
doesn't return to the normal.
This patch works around the issue by issueing abort if master activity

bnxt_qplib_alloc_dpi_tbl, dpit->dbr_bar_reg_iomem is freed via
pci_iounmap() in unmap_io error branch. After the callee returns err code,

bnxt_qplib_free_res()->bnxt_qplib_free_dpi_tbl() in the fail branch. Then
dpit->dbr_bar_reg_iomem is freed in the second time by pci_iounmap().
My patch set dpit->dbr_bar_reg_iomem to NULL after it is freed by
pci_iounmap() in the first time, to avoid the double free.

Our code analyzer reported a UAF.
In siw_alloc_mr(), it calls siw_mr_add_mem(mr,..). In the implementation of
siw_mr_add_mem(), mem is assigned to mr->mem and then mem is freed via
kfree(mem) if xa_alloc_cyclic() failed. Here, mr->mem still point to a
freed object. After, the execution continue up to the err_out branch of
siw_alloc_mr, and the freed mr->mem is used in siw_mr_drop_mem(mr).
My patch moves "mr->mem = mem" behind the if (xa_alloc_cyclic(..)<0) {}
section, to avoid the uaf.

When the error check in ath9k_hw_read_revisions() was added, it checked for
-EIO which is what ath9k_regread() in the ath9k_htc driver uses. However,
for plain ath9k, the register read function uses ioread32(), which just
returns -1 on error. So if such a read fails, it still gets passed through
and ends up as a weird mac revision in the log output.
Fix this by changing ath9k_regread() to return -1 on error like ioread32()
does, and fix the error check to look for that instead of -EIO.

The Intel xway phys offer the possibility to deactivate the integrated

If this was set by the bootloader, it must be ensured that the

Before commit 6e2d85ec0559 ("net: phy: Stop with excessive soft reset")
the LEDs were enabled by a soft-reset of the PHY (using
genphy_soft_reset). Initialize the XWAY_MDIO_LED with it's default
value (which is applied during a soft reset) instead of adding back
the soft reset. This brings back the default LED configuration while
still preventing an excessive amount of soft resets.

caused a stuck of receiving until a new frame was received. For example,
the following command from other device could cause this issue.

The previous code always cleared the interrupt flag of RX but checks
the interrupt flags in ravb_poll(). So, ravb_poll() could not call
ravb_rx() in the next time until a new RX frame was received if
ravb_rx() returned true. To fix the issue, always calls ravb_rx()
regardless the interrupt flags condition.

in a reference leak here.
Replace it with pm_runtime_resume_and_get to keep usage

The shifting of the u8 integers rq->caching by 26 bits to
the left will be promoted to a 32 bit signed int and then
sign-extended to a u64. In the event that rq->caching is
greater than 0x1f then all then all the upper 32 bits of
the u64 end up as also being set because of the int
sign-extension. Fix this by casting the u8 values to a
u64 before the 26 bit left shift.

Currently the expression ~nic_conf1 is always true because nic_conf1
is a u16 and according to 6.5.3.3 of the C standard the ~ operator
promotes the u16 to an integer before flipping all the bits. Thus
the top 16 bits of the integer result are all set so the expression
is always true. If the intention was to flip all the bits of nic_conf1
then casting the integer result back to a u16 is a suitabel fix.
Interestingly static analyzers seem to thing a bitwise ! should be
used instead of ~ for this scenario, so I think the original intent
of the expression may need some extra consideration.

[ Upstream commit 298b58f00c0f86868ea717426beb5c1198772f81 ]
The macro CN23XX_PEM_BAR1_INDEX_REG is being used to shift oct->pcie_port
(a u16) left 24 places. There are two subtle issues here, first the
shift gets promoted to an signed int and then sign extended to a u64.
If oct->pcie_port is 0x80 or more then the upper bits get sign extended
to 1. Secondly shfiting a u16 24 bits will lead to an overflow so it
needs to be cast to a u64 for all the bits to not overflow.
It is entirely possible that the u16 port value is never large enough
for this to fail, but it is useful to fix unintended overflows such
as this.
Fix this by casting the port parameter to the macro to a u64 before
the shift.

There are two "netif_running" checks in this driver. One is in
"lapbeth_xmit" and the other is in "lapbeth_rcv". They serve to make
sure that the LAPB APIs called in these functions are called before
"lapb_unregister" is called by the "ndo_stop" function.
However, these "netif_running" checks are unreliable, because it's
possible that immediately after "netif_running" returns true, "ndo_stop"
is called (which causes "lapb_unregister" to be called).
This patch adds locking to make sure "lapbeth_xmit" and "lapbeth_rcv" can
reliably check and ensure the netif is running while doing their work.

Plantronics Blackwire 3220 Series (047f:c056) sends HID reports twice
for each volume key press. This patch adds a quirk to hid-plantronics
for this product ID, which will ignore the second volume key press if
it happens within 5 ms from the last one that was handled.
The patch was tested on the mentioned model only, it shouldn't affect
other models, however, this quirk might be needed for them too.
Auto-repeat (when a key is held pressed) is not affected, because the
rate is about 3 times per second, which is far less frequent than once
in 5 ms.
