commit cb82a54904a99df9e8f9e9d282046055dae5a730 upstream.
This USB-C Hub (17ef:721e) based on the Realtek RTL8153B chip used to
use the cdc_ether driver. However, using this driver, with the system
suspended the device constantly sends pause-frames as soon as the
receive buffer fills up. This causes issues with other devices, where
some Ethernet switches stop forwarding packets altogether.
Using the Realtek driver (r8152) fixes this issue. Pause frames are no
longer sent while the host system is suspended.

Commit 468dfca38b1a6fbdccd195d875599cb7c8875cd9 added
"sectors_per_bit" and "bitmap_flush_interval".
Commit 84597a44a9d86ac949900441cea7da0af0f2f473 added

commit fcc42338375a1e67b8568dbb558f8b784d0f3b01 upstream.
If the origin device has a volatile write-back cache and the following
events occur:
1: After finishing merge operation of one set of exceptions,
merge_callback() is invoked.
2: Update the metadata in COW device tracking the merge completion.
This update to COW device is flushed cleanly.
3: System crashes and the origin device's cache where the recent
merge was completed has not been flushed.
During the next cycle when we read the metadata from the COW device,
we will skip reading those metadata whose merge was completed in
step (1). This will lead to data loss/corruption.
To address this, flush the origin device post merge IO before
updating the metadata.

This is because of the recent buffer overflow detection in the
commit 6a39e62abbaf ("lib: string.h: detect intra-object overflow in
fortified string functions")
Here acpi_device_bus_id->bus_id can only hold 14 characters, while the
the acpi_device_hid(device) returns a 22-char string
"HYPER_V_GEN_COUNTER_V1".
Per ACPI Spec v6.2, Section 6.1.5 _HID (Hardware ID), if the ID is a
string, it must be of the form AAA#### or NNNN####, i.e. 7 chars or 8
chars.
The field bus_id in struct acpi_device_bus_id was originally defined as
char bus_id[9], and later was enlarged to char bus_id[15] in 2007 in the
commit bb0958544f3c ("ACPI: use more understandable bus_id for ACPI
devices")
Fix the issue by changing the field bus_id to const char *, and use
kstrdup_const() to initialize it.

In current kernels small allocations are guaranteed to succeed and
dw_edma_alloc_burst() can't fail so this will not actually affect
runtime.

If the i2c device SCL bus being pulled up due to some exception before
message transfer done, the system cannot receive the completing interrupt
signal any more, it would not exit waiting loop until MAX_SCHEDULE_TIMEOUT
jiffies eclipse, that would make the system seemed hang up. To avoid that
happen, this patch adds a specific timeout for message transfer.

commit 3f9bce7a22a3f8ac9d885c9d75bc45569f24ac8b upstream
If we are using edge IRQs, new samples can arrive while processing
current interrupt since there are no hw guarantees the irq line
stays "low" long enough to properly detect the new interrupt.
In this case the new sample will be missed.
Polling FIFO status register in st_lsm6dsx_handler_thread routine
allow us to read new samples even if the interrupt arrives while
processing previous data and the timeslot where the line is "low"
is too short to be properly detected.

There was an 0/1 offset error in month handling for file metadata, causing

While stmmac_pltfr_remove calls sun8i_dwmac_exit, the sun8i_dwmac_init
and sun8i_dwmac_exit functions are also called by the stmmac_platform
suspend/resume callbacks. They may be called many times during the
device's lifetime and should not release resources used by the driver.
Furthermore, there was no error handling in case registering the MDIO
mux failed during probe, and the EPHY clock was never released at all.
Fix all of these issues by moving the deinitialization code to a driver
removal callback. Also ensure the EPHY is powered down before removal.

[ Upstream commit 7a68d725e4ea384977445e0bcaed3d7de83ab5b3 ]
Aligning to tx_ndp_modulus is not sufficient because the next align
call can be cdc_ncm_align_tail, which can add up to ctx->tx_modulus +
ctx->tx_remainder - 1 bytes. This used to lead to occasional crashes
on a Huawei 909s-120 LTE module as follows:
- the condition marked /* if there is a remaining skb [...] */ is true
so the swaps happen
- skb_out is set from ctx->tx_curr_skb
- skb_out->len is exactly 0x3f52
- ctx->tx_curr_size is 0x4000 and delayed_ndp_size is 0xac
(note that the sum of skb_out->len and delayed_ndp_size is 0x3ffe)
- the for loop over n is executed once
- the cdc_ncm_align_tail call marked /* align beginning of next frame */
increases skb_out->len to 0x3f56 (the sum is now 0x4002)
- the condition marked /* check if we had enough room left [...] */ is
false so we break out of the loop
- the condition marked /* If requested, put NDP at end of frame. */ is
true so the NDP is written into skb_out
- now skb_out->len is 0x4002, so padding_count is minus two interpreted
as an unsigned number, which is used as the length argument to memset,
leading to a crash with various symptoms but usually including
> Call Trace:
> <IRQ>
> cdc_ncm_fill_tx_frame+0x83a/0x970 [cdc_ncm]
> cdc_mbim_tx_fixup+0x1d9/0x240 [cdc_mbim]
> usbnet_start_xmit+0x5d/0x720 [usbnet]
The cdc_ncm_align_tail call first aligns on a ctx->tx_modulus
boundary (adding at most ctx->tx_modulus-1 bytes), then adds
ctx->tx_remainder bytes. Alternatively, the next alignment call can
occur in cdc_ncm_ndp16 or cdc_ncm_ndp32, in which case at most
ctx->tx_ndp_modulus-1 bytes are added.
A similar problem has occurred before, and the code is nontrivial to
reason about, so add a guard before the crashing call. By that time it
is too late to prevent any memory corruption (we'll have written past
the end of the buffer already) but we can at least try to get a warning
written into an on-disk log by avoiding the hard crash caused by padding
past the buffer with a huge number of zeros.
