In commit 58dc55f25631178ee74cd27185956a8f7dcb3e32 ("tipc: use generic
SKB list APIs to manage link transmission queue") we replace all list
traversal loops with the macros skb_queue_walk() or
skb_queue_walk_safe(). While the previous loops were based on the
assumption that the list was NULL-terminated, the standard macros
stop when the iterator reaches the list head, which is non-NULL.
In the function bclink_retransmit_pkt() this macro replacement has
lead to a bug. When we receive a BCAST STATE_MSG we unconditionally
call the function bclink_retransmit_pkt(), whether there really is
anything to retransmit or not, assuming that the sequence number
comparisons will lead to the correct behavior. However, if the
transmission queue is empty, or if there are no eligible buffers in
the transmission queue, we will by mistake pass the list head pointer
to the function tipc_link_retransmit(). Since the list head is not a
valid sk_buff, this leads to a crash.
In this commit we fix this by only calling tipc_link_retransmit()
if we actually found eligible buffers in the transmission queue.

In C one can either use '\0' or '\x00' (or '\000') to add a NUL byte to
a string. '\0x00' isn't part of these and will in fact result in a
single NUL followed by "x00". This fixes that.

Commit b856a59141b1 (arm/arm64: KVM: Reset the HCR on each vcpu
when resetting the vcpu) moved the init of the HCR register to
happen later in the init of a vcpu, but left out the fixup
done in kvm_reset_vcpu when preparing for a 32bit guest.
As a result, the 32bit guest is run as a 64bit guest, but the
rest of the kernel still manages it as a 32bit. Fun follows.
Moving the fixup to vcpu_reset_hcr solves the problem for good.

If uprobes are single stepped for example with gdb, the behavior should
now be correct. Before this patch, when gdb was single stepping a uprobe,
the result was a SIGILL.
When PER is active for any storage alteration and a uprobe is hit, a storage
alteration event is indicated. These over indications are filterd out by gdb,
if no change has happened within the observed area.

Sleep in atomic context happened on Trats2 board after inserting or
removing SD card because mmc_gpio_get_cd() was called under spin lock.
Fix this by moving card detection earlier, before acquiring spin lock.
The mmc_gpio_get_cd() call does not have to be protected by spin lock
because it does not access any sdhci internal data.
The sdhci_do_get_cd() call access host flags (SDHCI_DEVICE_DEAD). After
moving it out side of spin lock it could theoretically race with driver
removal but still there is no actual protection against manual card
eject.

In commit 5491ce3f79ee ("mmc: sdhci-pxav3: add support for the Armada
38x SDHCI controller"), the sdhci-pxav3 driver was extended to include
support for the SDHCI controller found in the Armada 38x
processor. This mainly involved adding some MBus window related
configuration.
However, this configuration is currently done too early in ->probe():
it is done before clocks are enabled, while this configuration
involves touching the registers of the controller, which will hang the
SoC if the clock is disabled. It wasn't noticed until now because the
bootloader typically leaves gatable clocks enabled, but in situations
where we have a deferred probe (due to a CD GPIO that cannot be taken,
for example), then the probe will be re-tried later, after a clock
disable has been done in the exit path of the failed probe attempt of
the device. This second probe() will hang the system due to the clock
being disabled.
This can for example be produced on Armada 385 GP, which has a CD GPIO
connected to an I2C PCA9555. If the driver for the PCA9555 is not
compiled into the kernel, then we will have the following sequence of
events:
1. The SDHCI probes
2. It does the MBus configuration (which works, because the clock is
left enabled by the bootloader)
3. It enables the clock
4. It tries to get the CD GPIO, which fails due to the driver being
missing, so -EPROBE_DEFER is returned.
5. Before returning -EPROBE_DEFER, the driver cleans up what was
done, which includes disabling the clock.
6. Later on, the SDHCI probe is tried again.
7. It does the MBus configuration, which hangs because the clock is
no longer enabled.
This commit does the obvious fix of doing the MBus configuration after
the clock has been enabled by the driver.

Re-tuning for HS400 mode must be done in HS200
mode. Currently there is no support for that.
That needs to be reflected in the code.
Specifically, if tuning is executed in HS400 mode
then return an error, and do not start the
tuning timer if HS200 tuning is being done prior
to switching to HS400.
Note that periodic re-tuning is not expected
to be needed for HS400 but re-tuning is still
needed after the host controller has lost power.
In the case of suspend/resume that is not necessary
because the card is fully re-initialised. That
just leaves runtime suspend/resume with no support
for HS400 re-tuning.

Re-tuning requires that the maximum data length
is limited to 4MiB. The code currently changes
max_blk_count in an attempt to achieve that.
This is wrong because max_blk_count is a different
limit, but it is also un-necessary because
max_req_size is 512KiB anyway. Consequently, the
changes to max_blk_count are removed and the
comment for max_req_size adjusted accordingly.
The comment is also tweaked to show that the 512KiB
limit is a SDMA limit not an ADMA limit.

The following patchset contains netfilter/ipvs fixes, they are:
1) Small fix for the FTP helper in IPVS, a diff variable may be left
unset when CONFIG_IP_VS_IPV6 is set. Patch from Dan Carpenter.
2) Fix nf_tables port NAT in little endian archs, patch from leroy
christophe.
3) Fix race condition between conntrack confirmation and flush from
userspace. This is the second reincarnation to resolve this problem.
4) Make sure inner messages in the batch come with the nfnetlink header.
5) Relax strict check from nfnetlink_bind() that may break old userspace
applications using all 1s group mask.
6) Schedule removal of chains once no sets and rules refer to them in
the new nf_tables ruleset flush command. Reported by Asbjoern Sloth
Toennesen.
Note that this batch comes later than usual because of the short
winter holidays.

which expands to
(__builtin_expect(!!(offset), 0) < 0),
never evaluates to true. Therefore, when sending packets with

if the creation of the layer 2 header fails.

Commit d75b1ade567f ("net: less interrupt masking in NAPI") uncovered
wrong alx_poll() behavior.
A NAPI poll() handler is supposed to return exactly the budget when/if
napi_complete() has not been called.
It is also supposed to return number of frames that were received, so
that netdev_budget can have a meaning.
Also, in case of TX pressure, we still have to dequeue received
packets : alx_clean_rx_irq() has to be called even if
alx_clean_tx_irq(alx) returns false, otherwise device is half duplex.

Fix for BUG_ON(anon_vma->degree) splashes in unlink_anon_vmas() ("kernel
BUG at mm/rmap.c:399!") caused by commit 7a3ef208e662 ("mm: prevent
endless growth of anon_vma hierarchy")
Anon_vma_clone() is usually called for a copy of source vma in
destination argument. If source vma has anon_vma it should be already
in dst->anon_vma. NULL in dst->anon_vma is used as a sign that it's
called from anon_vma_fork(). In this case anon_vma_clone() finds
anon_vma for reusing.
Vma_adjust() calls it differently and this breaks anon_vma reusing
logic: anon_vma_clone() links vma to old anon_vma and updates degree
counters but vma_adjust() overrides vma->anon_vma right after that. As
a result final unlink_anon_vmas() decrements degree for wrong anon_vma.
This patch assigns ->anon_vma before calling anon_vma_clone().

Commit fee7e49d4514 ("mm: propagate error from stack expansion even for
guard page") made sure that we return the error properly for stack
growth conditions. It also theorized that counting the guard page
towards the stack limit might break something, but also said "Let's see
if anybody notices".
Somebody did notice. Apparently android-x86 sets the stack limit very
close to the limit indeed, and including the guard page in the rlimit
check causes the android 'zygote' process problems.
So this adds the (fairly trivial) code to make the stack rlimit check be
against the actual real stack size, rather than the size of the vma that
includes the guard page.

"These have been around since 3.17 and in kgdb-next for the last 9
weeks and some will go back to -stable.
Summary of changes:
Cleanups

Fixes
- kgdb/kdb: Allow access on a single core, if a CPU round up is
deemed impossible, which will allow inspection of the now "trashed"
kernel
- kdb: Add enable mask for the command groups
- kdb: access controls to restrict sensitive commands"

For PGR reservation of type Write Exclusive Access, allow all non
reservation holding I_T nexuses with active registrations to READ
from the device.
This addresses a bug where active registrations that attempted
to READ would result in an reservation conflict.

Now that fabric_max_sectors is no longer used to enforce the maximum
I/O size, go ahead and drop it's left-over usage in target-core and
associated backend drivers.

This patch drops the arbitrary maximum I/O size limit in sbc_parse_cdb(),
which currently for fabric_max_sectors is hardcoded to 8192 (4 MB for 512
byte sector devices), and for hw_max_sectors is a backend driver dependent
value.
This limit is problematic because Linux initiators have only recently
started to honor block limits MAXIMUM TRANSFER LENGTH, and other non-Linux
based initiators (eg: MSFT Fibre Channel) can also generate I/Os larger
than 4 MB in size.
Currently when this happens, the following message will appear on the
target resulting in I/Os being returned with non recoverable status:
SCSI OP 28h with too big sectors 16384 exceeds fabric_max_sectors: 8192
Instead, drop both [fabric,hw]_max_sector checks in sbc_parse_cdb(),
and convert the existing hw_max_sectors into a purely informational
attribute used to represent the granuality that backend driver and/or
subsystem code is splitting I/Os upon.
Also, update FILEIO with an explicit FD_MAX_BYTES check in fd_execute_rw()
to deal with the one special iovec limitiation case.
v2 changes:
- Drop hw_max_sectors check in sbc_parse_cdb()
