While trying an ESP transport mode encryption for UDPv6 packets of
datagram size 1436 with MTU 1500, checksum error was observed in
the secondary fragment.
This error occurs due to the UDP payload checksum being missed out
when computing the full checksum for these packets in
udp6_hwcsum_outgoing().

Issue where unprintable characters can occur or output is cut off over
the serial uart / linux console depending on timing.
Problem occurs when changing the serial baud rate when setting up the
new console.The bcm63xx driver does a disable and flush of the uart tx
fifo while there is data still in the tx fifo.
If the tx fifo still has data it is trying to send out, we need to wait
until it is empty before disabling and flushing the uart.
When we now go to change the uart parameters including speed we check
if there is data currently in the tx fifo.If there is was mdelay(10)
and check again.If it tries 3 times and still has data in it we just
continue and sacrifice the tx fifo buffer.
A cleaner and more preferred approach would be to remove :
- spin_lock_irqsave()
- bcm_uart_disable()
- bcm_uart_flush()
However it is not clear if the author put those in to fix another
underlying issue.As a result this solution is a safer approach.
Output before the fix:
[0.306000] 14e00520.serial: ttyS0 at MMIO 0x14e00520 (irq = 9, base_baud = 1687500) is a° 0.315000] console[ttyS0] enabled

Paul reported, that low rates like B300 make the driver to hang in
mxser_wait_until_sent. His debugging tackled the issue down to the
info->timeout computation in mxser_set_baud. Obviously, ints are used
there and they easily overflow with these low rates: B300 makes
info->timeout to be -373.
So switch all these types to unsigned as it ought to be. And use the u64
domain to perform the computation as in the worst case, we need 35 bits
to store the computed value (before division).
And use do_div not to break 32 bit kernels.

Commit 4c39d4b949 ("usb: xhci: use bus->sysdev for DMA configuration")
updated the method determining DMA for XHCI from sysdev. However, this
patch broke the ability to enumerate the FWNODE from parent ACPI devices
from the child plat XHCI device.
Currently, xhci_plat is not set up properly when the parent device is an
ACPI node. The conditions that xhci_plat_probe should satisfy are
1. xhci_plat comes from firmware
2. xhci_plat is child of a device from firmware (dwc3-plat)
3. xhci_plat is grandchild of a pci device (dwc3-pci)
Case 2 is covered when the child is an OF node (by checking
sysdev->parent->of_node), however, an ACPI parent will return NULL in
the of_node check and will thus not result in sysdev being set to
sysdev->parent
[ 17.591549] xhci-hcd: probe of xhci-hcd.6.auto failed with error -5
This change adds a check for ACPI to completely allow for condition 2.
This is done by first checking if the parent node is of type ACPI (e.g.,
dwc3-plat) and set sysdev to sysdev->parent if either of the two
following conditions are met:
1: If fwnode is empty (in the case that platform_device_add_properties
was not called on the allocated platform device)
2: fwnode exists but is not of type ACPI (this would happen if
platform_device_add_properties was called on the allocated device.
Instead of type FWNODE_ACPI, you would end up with FWNODE_PDATA)

The current udev rules cause modules to be loaded on all device events save
for "remove". With the introduction of KOBJ_BIND/KOBJ_UNBIND this causes
issues, as driver modules that have devices bound to their drivers get
immediately reloaded, and it appears to the user that module unloading doe
snot work.
The standard udev matching rule is foillowing:
ENV{MODALIAS}=="?*", RUN{builtin}+="kmod load $env{MODALIAS}"
Given that MODALIAS data is not terribly useful for UNBIND event, let's zap
it from the generated uevent environment until we get userspace updated
with the correct udev rule that only loads modules on "add" event.

Merge tag 'iwlwifi-for-kalle-2017-09-15' of git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-fixes
First set of fixes for 4.14
* A couple of bugzilla bugs related to multicast handling;
* Two fixes for WoWLAN bugs that were causing queue hangs and
re-initialization problems;
* Two fixes for potential uninitialized variable use reported by Dan
Carpenter in relation to a recently introduced patch;
* A fix for buffer reordering in the newly supported 9000 device
family;
* Fix a race when starting aggregation;
* Small fix for a recent patch to wake mac80211 queues;
* Send non-bufferable management frames in the generic queue so they
are not sent on queues that are under power-save;
There is no plan yet to do a v2 board. And even if we were to do it only
some IPs would actually change, so it be best to add suffixes at that
point, not now !

If we don't assign a TRB to ep0 requests, we won't be able to unmap
the request later on resulting in starvation of DMA resources.

This fixes a NULL pointer dereference on RPi 2 with multi_v7_defconfig.
The function page_address() could return NULL with enabled CONFIG_HIGHMEM.
So fix this by using kmap() instead.

When cursor is at beginning of an empty or whitespace-only line and
speakup-r typed, kernel locks up. This happens because deadlock of in
input_event function over dev->event_lock, as demonstrated by lockdep
logs. The reason for that is speakup simulates a down arrow - because
cursor is at an empty line - while inside key press notifier handler
which is ultimately triggered from input_event function. The simulated
key press leads to input_event being called again, this time under its
own context. So the spinlock is dev->event_lock is acquired while still
being held.
This patch ensures that key press is not simulated from inside key press
notifier handler. Instead it delegates to cursor_timer. It starts the
timer and passes RA_DOWN_ARROW as argument. When timer handler runs and
sees RA_DOWN_ARROW, it will then call kbd_fakekey2(RA_DOWN_ARROW) which
will correctly simulate the keypress inside timer context.
When not inside key press notifier callback, the behaviour will remain
the same as before this patch.

With gcc-4.1.2:
drivers/staging/pi433/rf69.c: In function ‘rf69_set_dio_mapping’:
drivers/staging/pi433/rf69.c:566: warning: ‘regaddr’ may be used uninitialized in this function

drivers/staging/pi433/rf69.c:564: warning: ‘mask’ may be used uninitialized in this function
While this is a false positive, it can easily be fixed by moving the
limit check into the "default" case of the switch statement.

The call to _rtl_dbg_trace via macro HALMAC_RT_TRACE will trigger a null
pointer deference on a null driver_adapter. Fix this by assigning
driver_adapter earlier to halmac_adapter->driver_adapter before the tracing
call so that a non-null driver_adapter is passed instead.
I should have spotted these with an earlier patch I sent, but I overlooked
these in the rather large CoverityScan logs.

Current program_page function did following operation:
1. read page (with ECC OFF)
2. modify the page
3. write the page (with ECC ON)
For some case(buggy flash Chip), while read the page without ECC ON,
we may read the page with bit flip error and modify that bad page without
knowing the bit flip error on that page.
also we re-calculate the hash for bad page and write it.
This could bring potential in-consistency problem with Flash data.
Verify this logic with GIGA DEVICE Part(GD5F2GQ4RCFIG):
we see this in-conststency problem wit Giga Device and fix on
this patch resovle that issue.

gcc-4.6 causes a harmless warning about the init function:
WARNING: vmlinux.o(.text+0xed62c2): Section mismatch in reference from the function init_unisys() to the function .init.text:visorutil_spar_detect()
The function init_unisys() references
the function __init visorutil_spar_detect().
This is often because init_unisys lacks a __init
annotation or the annotation of visorutil_spar_detect is wrong.
It appears that newer versions inline visorutil_spar_detect(),
end up with an empty __init section. This marks the module
entry points as __init and __exit respectively, which avoids
the warning and slightly reduces the runtime code size.
