When support for _FIT was added, the code presumed that the data
returned by the _FIT method is identical to the NFIT table, which
starts with an acpi_table_header. However, the _FIT is defined
to return a data in the format of a series of NFIT type structure
entries and as a method, has an acpi_object header rather tahn
an acpi_table_header.
To address the differences, explicitly save the acpi_table_header
from the NFIT, since it is accessible through /sys, and change
the nfit pointer in the acpi_desc structure to point to the
table entries rather than the headers.

The size of NFIT tables don't necessarily match the size of the
data structures that we use for them. For example, the NVDIMM
Control Region Structure table is shorter for a device with
no block control windows than for a device with block control windows.
Other tables, such as Flush Hint Address Structure and the Interleave
Structure are variable length by definition.
Account for the size difference when comparing table entries by
using the actual table size from the table header if it's less
than the structure size.

Dmitry provided a syzkaller (http://github.com/google/syzkaller)
generated program that triggers the WARNING at
net/ipv4/tcp.c:1729 in tcp_recvmsg() :
WARN_ON(tp->copied_seq != tp->rcv_nxt &&
!(flags & (MSG_PEEK | MSG_TRUNC)));
His program is specifically attempting a Cross SYN TCP exchange,
that we support (for the pleasure of hackers ?), but it looks we
lack proper tcp->copied_seq initialization.

The gianfar driver has recently been enabled on arm64 but fails to build
since it check the return value of platform_get_irq() against NO_IRQ. Fix
this by instead checking for a negative error code.
Even on ARM where this code was previously being built this check was
incorrect since platform_get_irq() returns a negative error code which
may not be exactly the (unsigned int)(-1) that NO_IRQ is defined to be.

This driver can be built on arm64 but relies on NO_IRQ to check the return
value of irq_of_parse_and_map() which fails to build on arm64 because the
architecture does not provide a NO_IRQ. Fix this to correctly check the
return value of irq_of_parse_and_map().
Even on ARM systems where the driver was previously used the check was
broken since on ARM NO_IRQ is -1 but irq_of_parse_and_map() returns 0 on
error.

sendpage did not care about credentials at all. This could lead to
situations in which because of fd passing between processes we could
append data to skbs with different scm data. It is illegal to splice those

fill out the scm details.

The receive skb buffers can be preallocated when the link is opened
according to mtu size.
While testing on a network environment with not standard MTU (e.g. 3000),
a panic occurred if an incoming packet had a length greater than rx skb
buffer size. This is because the HW is programmed to copy, from the DMA,
an Jumbo frame and the Sw must check if the allocated buffer is enough to
store the frame.

In case of the st,tx-retime-src is missing from device-tree
(it's an optional field) the driver will invoke the strcasecmp to check
which clock has been selected and this is a bug; the else condition
is needed.
In the dwmac_setup, the "rs" variable, passed to the strcasecmp, was not
initialized and the compiler, depending on the options adopted, could
take it in some different part of the stack generating the hang in such

Assume a filesystem with 4KB blocks. When a file has size 1000 bytes and
we issue direct IO read at offset 1024, blockdev_direct_IO() reads the
tail of the last block and the logic for handling short DIO reads in
dio_complete() results in a return value -24 (1000 - 1024) which
obviously confuses userspace.
Fix the problem by bailing out early once we sample i_size and can
reliably check that direct IO read starts beyond i_size.

For the first way, i can't find any related rule in AHCI Spec. The

I2C controller used in Keystone SoC has an undocumented peculiarity which
results in SDA-SCL margins being dependent on module clock. Driving high
capacity bus near its limits can result in STOP condition sometimes being
understood as REPEATED-START by slaves (or NACK instead of ACK, etc...).
Driving the module with higher clocks increases the margin between SDA and SCL
transitions, making the operations with higher bus rates more robust. Therefore,
target the module clock to 12MHz instead of 7MHz, still staying within
the specification limits.
Before the change STOP timing looked like this on 400kHz:
SDA ----------+ +----
\ /
\ /
+----+
(1)
SCL --+ +------------
\ /
\ /
+----+
(2)
While only point (1) signals STOP, point (2) could be incorrectly recognized as
repeated-START (almost no margin between SDA and SCL transitions).
After the change there is at least 600ns margin measured between SCL fall and
SDA fall during STOP generation:
SDA ------+ +----
\ /
\ /
+----+
SCL --+ +--------
\ /
\ /
+----+
->| |<- 600ns
->| |<- tSUSTO
So called tSUSTO (setup time for STOP condition) is still slightly higher than
600ns, so no problem here.
