Commit 6e7333d "net: add rx_nohandler stat counter" added the new entry
rx_nohandler into struct rtnl_link_stats64. Unfortunately the bna
driver foolishly depends on the structure. It uses part of it for
ethtool statistics and it's not bad but the driver assumes its size
is constant as it defines string for each existing entry. The problem
occurs when the structure is extended because you need to modify bna
driver as well. If not any attempt to retrieve ethtool statistics results
in crash in bnad_get_strings().
The patch changes BNAD_ETHTOOL_STATS_NUM so it counts real number of
strings in the array and also removes rtnl_link_stats64 entries that
are not used in output and are always zero.

A malicious TCP receiver, sending SACK, can force the sender to split
skbs in write queue and increase its memory usage.
Then, when socket is closed and its write queue purged, we might
overflow sk_forward_alloc (It becomes negative)
sk_mem_reclaim() does nothing in this case, and more than 2GB
are leaked from TCP perspective (tcp_memory_allocated is not changed)
Then warnings trigger from inet_sock_destruct() and
sk_stream_kill_queues() seeing a not zero sk_forward_alloc
All TCP stack can be stuck because TCP is under memory pressure.
A simple fix is to preemptively reclaim from sk_mem_uncharge().
This makes sure a socket wont have more than 2 MB forward allocated,
after burst and idle period.

If a TCP socket gets a large write queue, an overflow can happen
in a test in __tcp_retransmit_skb() preventing all retransmits.
The flow then stalls and resets after timeouts.

In case of error during netback_probe() (e.g. an entry missing on the
xenstore) netback_remove() is called on the new device, which will set
the device backend state to XenbusStateClosed by calling
set_backend_state(). However, the backend state wasn't initialized by
netback_probe() at this point, which will cause and invalid transaction
and set_backend_state() to BUG().
Initialize the backend state at the beginning of netback_probe() to
XenbusStateInitialising, and create two new valid state transitions on
set_backend_state(), from XenbusStateInitialising to XenbusStateClosed,
and from XenbusStateInitialising to XenbusStateInitWait.

Given following simplified device hierarchy:
// PCI device having BAR0 (RMEM) split between 4 GPIO devices.
Device (P2S)
{

Device (GPO0)
{

Name (_UID, 1)
Name (_CRS, ResourceTemplate () {
Memory32Fixed (ReadWrite, 0, 0x4000, RMEM + 0x0000)
})
}
Device (GPO1)
{
Name (_HID, "INT3452")
Name (_UID, 2)
Name (_CRS, ResourceTemplate () {
Memory32Fixed (ReadWrite, 0, 0x4000, RMEM + 0x4000)
})
}
Device (GPO2)
{
Name (_HID, "INT3452")
Name (_UID, 3)
Name (_CRS, ResourceTemplate () {
Memory32Fixed (ReadWrite, 0, 0x4000, RMEM + 0x8000)
})
}
Device (GPO3)
{
Name (_HID, "INT3452")
Name (_UID, 4)
Name (_CRS, ResourceTemplate () {
Memory32Fixed (ReadWrite, 0, 0x4000, RMEM + 0xc000)
})
}
}
The current ACPI platform enumeration code allocates resources from the
global MMIO resource pool (/proc/iomem) for all the four GPIO devices.
After this PCI core calls pcibios_resource_survey() to allocate resources
for all PCI devices including the parent device for these GPIO devices
(P2S). Since that resource range has already been reserved the allocation
fails.
The reason for this is that we never bother with parent device's resources
when ACPI platform devices are created.
Fix this by checking whether there is a parent device and in that case make
sure we assign correct parent resource to the resources for the child ACPI
platform device. Currently we only deal with parent devices if they are PCI
devices but we may expand this later to cover other bus types as well.

This patch cleans up sysfs table signature handling code:
1. Convert the signature handling code to use the ACPICA APIs to
benefit from the future improvements of the APIs.
2. Add 'filename' attribute in order to handle both BE/LE name tags.
3. Add instance check in order to avoid the possible buffer overflow
related to the table file name.

OEM tables can be installed via RSDT/XSDT, in this case, they have already
been created under /sys/firmware/acpi/tables.
For this kind of tables, normally LoadTable opcode will be executed to load
them. If LoadTable opcode is executed after acpi_sysfs_init(),
acpi_sysfs_table_handler() will be invoked, thus a redundant table file
will be created under /sys/firmware/acpi/tables/dynamic. Then running
"acpidump" on such platform results in an error, complaining blank empty
table (see Link 1 below).
The bug can be reproduced by customizing an OEM1 table, allowing it to be
overridden via 'table_sigs' (drivers/acpi/tables.c), adding the following
code to the customized DSDT to load it:
Name (OEMH, Zero)
Name (OEMF, One)
If (LEqual (OEMF, One)) {
Store (LoadTable ("OEM1", "Intel", "Test"), OEMH)
Store (Zero, OEMF)
}
In order to make sure that the OEM1 table is installed after
acpi_sysfs_init(), acpi_sysfs_init() can be moved before invoking
acpi_load_tables(). Then the following command execution result can be
seen:
# acpidump > acpidump.txt
Could not read table header: /sysfs/firmware/acpi/tables/dynamic/OEM12
Could not get ACPI table at index 17, AE_BAD_HEADER

When CONFIG_OPTIMIZE_INLINING is set and we are building with -Wmaybe-uninitialized
enabled, we can get a warning for the opp core driver:
drivers/base/power/opp/core.c: In function 'dev_pm_opp_set_rate':
drivers/base/power/opp/core.c:560:8: warning: 'ou_volt_min' may be used uninitialized in this function [-Wmaybe-uninitialized]
This has only now appeared as a result of commit 797da5598f3a ("PM / devfreq:
Add COMPILE_TEST for build coverage"), which makes the driver visible in
some configurations that didn't have it before.
The warning is a false positive that I got with gcc-6.1.1, but there is
a simple workaround in removing the local variables that we get warnings
for (all three are affected depending on the configuration). This also
makes the code easier to read.

failed probe.
- SA1111 and PCMCIA suspend/resume was broken:
The PCMCIA "ds" layer was using the legacy bus suspend/resume
methods, which the core PM code is no longer calling as a result of
device_pm_check_callbacks() introduced in commit aa8e54b559479
("PM / sleep: Go direct_complete if driver has no callbacks").
SA1111 was broken due to changes to PCMCIA which makes PCMCIA
suspend itself later than the SA1111 code expects, and resume
before the SA1111 code has initialised access to the pcmcia
sub-device.
- the default SA1111 interrupt mask polarity got messed up when it
was converted to use a dynamic interrupt base number for its
interrupts.
- fix platform_get_irq() error code propagation, which was causing
problems on platforms where the interrupt may not be available at
probe time in DT setups.
- fix the lack of clock to PCMCIA code on PXA platforms, which was
omitted in conversions of PXA to CCF.
- fix an oops in the PXA PCMCIA code caused by a previous commit not
realising that Lubbock is different from the rest of the PXA PCMCIA
drivers.
- ensure that SA1111 low-level PCMCIA drivers propagate their error
codes to the main probe function, rather than the driver silently
accepting a failure.
- fix the sa11xx debugfs reporting of timing information, which
always indicated zero due to the clock being a factor of 1000 out.
- fix the polarity of the status change signal reported from the
sockets.
Lastly, one ARM specific commit from Stefan Agner fixing the LPAE
cache attributes"

The userspace memory region 'mr' is allocated with kzalloc in
__rvt_alloc_mr however it is incorrectly being freed with vfree in
__rvt_free_mr. Fix this by using kfree to free it.

rxe_requester() is sending a pkt with rxe_xmit_packet() and
then calls rxe_update() to update the wqe and qp's psn values.
But sometimes the response is received before the requester
had time to update the wqe in which case the completer
acts on errornous wqe values.
This fix updates the wqe and qp before actually sending
the request and rolls back when xmit fails.

When handling ack for atomic opcodes like "fetch&add"
or "cmp&swp", the method send_atomic_ack() saves the ack
before sending it, in case it gets lost and never reach the
requester. In which case the method duplicate_request()
will need to find it using the duplicated request.psn.
But send_atomic_ack() used a wrong psn value and thus
the above ack was never found.
This fix uses the ack.psn to locate the ack in case
its needed.
This fix also copies the ack packet to the skb's control buffer
since duplicate_request() will need it when calling rxe_xmit_packet()
