Sorry about the late pull request for 4.9, but we have one more
important Bluetooth patch that should make it to the release. It fixes
connection creation for Bluetooth LE controllers that do not have a
public address (only a random one).
Please let me know if there are any issues pulling. Thanks.

This leads to crashes if UDPlite header is pulled twice, which happens
starting from commit e6afc8ace6 ("udp: remove headers from UDP packets

Bug found by syzkaller team, thanks a lot guys !
Note that backlog use in UDP/UDPlite is scheduled to be removed starting

em_jmp_far and em_ret_far assumed that setting IP can only fail in 64
bit mode, but syzkaller proved otherwise (and SDM agrees).
Code segment was restored upon failure, but it was left uninitialized
outside of long mode, which could lead to a leak of host kernel stack.
We could have fixed that by always saving and restoring the CS, but we
take a simpler approach and just break any guest that manages to fail
as the error recovery is error-prone and modern CPUs don't need emulator
for this.

When an ipv6 address has the tentative flag set, it can't be
used as source for egress traffic, while the associated route,
if any, can be looked up and even stored into some dst_cache.
In the latter scenario, the source ipv6 address selected and
stored in the cache is most probably wrong (e.g. with
link-local scope) and the entity using the dst_cache will
experience lack of ipv6 connectivity until said cache is
cleared or invalidated.
Overall this may cause lack of connectivity over most IPv6 tunnels
(comprising geneve and vxlan), if the first egress packet reaches
the tunnel before the DaD is completed for the used ipv6
address.
This patch bumps a new genid after that the IFA_F_TENTATIVE flag
is cleared, so that dst_cache will be invalidated on
next lookup and ipv6 connectivity restored.

Since MIPSr6 the Wired register is split into 2 fields, with the upper
16 bits of the register indicating a limit on the value that the wired
entry count in the bottom 16 bits of the register can take. This means
that simply reading the wired register doesn't get us a valid TLB entry
index any longer, and we instead need to retrieve only the lower 16 bits
of the register. Introduce a new num_wired_entries() function which does
this on MIPSr6 or higher and simply returns the value of the wired
register on older architecture revisions, and make use of it when
reading the number of wired entries.
Since commit e710d66683 ("MIPS: tlb-r4k: If there are wired entries,
don't use TLBINVF") we have been using a non-zero number of wired
entries to determine whether we should avoid use of the tlbinvf
instruction (which would invalidate wired entries) and instead loop over
TLB entries in local_flush_tlb_all(). This loop begins with the number
of wired entries, or before this patch some large bogus TLB index on
MIPSr6 systems. Thus since the aforementioned commit some MIPSr6 systems
with FTLBs have been prone to leaving stale address translations in the
FTLB & crashing in various weird & wonderful ways when we later observe
the wrong memory.

When loading the TX fifo to receive bytes on the I2C bus, we incorrectly
count the number of bytes:
rx_limit = dev->rx_fifo_depth - dw_readl(dev, DW_IC_RXFLR);
while (buf_len > 0 && tx_limit > 0 && rx_limit > 0) {
if (rx_limit - dev->rx_outstanding <= 0)
break;
rx_limit--;
dev->rx_outstanding++;
}
DW_IC_RXFLR indicates how many bytes are available to be read in the
FIFO, dev->rx_fifo_depth is the FIFO size, and dev->rx_outstanding is
the number of bytes that we've requested to be read so far, but which
have not been read.
Firstly, increasing dev->rx_outstanding and decreasing rx_limit and then
comparing them results in each byte consuming "two" bytes in this
tracking, so this is obviously wrong.
Secondly, the number of bytes that _could_ be received into the FIFO at
any time is the number of bytes we have so far requested but not yet
read from the FIFO - in other words dev->rx_outstanding.
So, in order to request enough bytes to fill the RX FIFO, we need to
request dev->rx_fifo_depth - dev->rx_outstanding bytes.
Modifying the code thusly results in us reaching the maximum number of
bytes outstanding each time we queue more "receive" operations, provided
the transfer allows that to happen.

Stas Nichiporovich reports oops in nf_nat_bysource_cmp(), trying to
access nf_conn struct at address 0xffffffffffffff50.
This is the result of fetching a null rhash list (struct embedded at
offset 176; 0 - 176 gets us ...fff50).
The problem is that conntrack entries are allocated from a
SLAB_DESTROY_BY_RCU cache, i.e. entries can be free'd and reused
on another cpu while nf nat bysource hash access the same conntrack entry.
Freeing is fine (we hold rcu read lock); zeroing rhlist_head isn't.
-> Move the rhlist struct outside of the memset()-inited area.

As Liping Zhang reports, after commit a8b1e36d0d ("netfilter: nft_dynset:
fix element timeout for HZ != 1000"), priv->timeout was stored in jiffies,
while set->timeout was stored in milliseconds. This is inconsistent and
incorrect.
Firstly, we already call msecs_to_jiffies in nft_set_elem_init, so
priv->timeout will be converted to jiffies twice.
Secondly, if the user did not specify the NFTA_DYNSET_TIMEOUT attr,
set->timeout will be used, but we forget to call msecs_to_jiffies
when do update elements.
Fix this by using jiffies internally for traditional sets and doing the
conversions to/from msec when interacting with userspace - as dynset
already does.
This is preferable to doing the conversions, when elements are inserted or
updated, because this can happen very frequently on busy dynsets.

I got offlist bug report about failing connections and high cpu usage.
This happens because we hit 'elasticity' checks in rhashtable that
refuses bucket list exceeding 16 entries.
The nat bysrc hash unfortunately needs to insert distinct objects that
share same key and are identical (have same source tuple), this cannot
be avoided.
Switch to the rhlist interface which is designed for this.
The nulls_base is removed here, I don't think its needed:
A (unlikely) false positive results in unneeded port clash resolution,
a false negative results in packet drop during conntrack confirmation,
when we try to insert the duplicate into main conntrack hash table.
Tested by adding multiple ip addresses to host, then adding
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
... and then creating multiple connections, from same source port but
different addresses:
for i in $(seq 2000 2032);do nc -p 1234 192.168.7.1 $i > /dev/null & done
(all of these then get hashed to same bysource slot)
Then, to test that nat conflict resultion is working:
nc -s 10.0.0.1 -p 1234 192.168.7.1 2000
nc -s 10.0.0.2 -p 1234 192.168.7.1 2000

The comparator works like memcmp, i.e. 0 means objects are equal.
In other words, when objects are distinct they are treated as identical,
when they are distinct they are allegedly the same.
The first case is rare (distinct objects are unlikely to get hashed to
same bucket).
The second case results in unneeded port conflict resolutions attempts.

When we inject a level triggerered interrupt (and unless it
is backed by the physical distributor - timer style), we request
a maintenance interrupt. Part of the processing for that interrupt
is to feed to the rest of KVM (and to the eventfd subsystem) the
information that the interrupt has been EOIed.
But that notification only makes sense for SPIs, and not PPIs
(such as the PMU interrupt). Skip over the notification if
the interrupt is not an SPI.

The probe function requests the interrupt before initializing
the ddp component. Which leads to a null pointer dereference at boot.
Fix this by requesting the interrput after all components got

Tlpx, Ths-prepare, Ths-zero, Ths-trail,Ths-exit) when enter and exit LP

So need to multiply a coefficient to offset the extra signal's effect.

When configured with CONFIG_PPC_EARLY_DEBUG_OPAL=y the kernel expects
the OPAL entry and base addresses to be passed in r8 and r9
respectively. Currently the wrapper does not attempt to restore these
values before entering the decompressed kernel which causes the kernel
to branch into whatever happens to be in r9 when doing a write to the
OPAL console in early boot.
This patch adds a platform_ops hook that can be used to branch into the
new kernel. The OPAL console driver patches this at runtime so that if
the console is used it will be restored just prior to entering the
kernel.

drm/radeon: fix power state when port pm is unavailable (v2)
drm/amdgpu: fix power state when port pm is unavailable
drm/amd/powerplay: avoid out of bounds access on array ps.
The commit 8dfbcc4351 ("[media] xc2028: avoid use after free") tried
to address the reported use-after-free by clearing the reference.
However, it's clearing the wrong pointer; it sets NULL to
priv->ctrl.fname, but it's anyway overwritten by the next line
memcpy(&priv->ctrl, p, sizeof(priv->ctrl)).
OTOH, the actual code accessing the freed string is the strcmp() call
with priv->fname:
if (!firmware_name[0] && p->fname &&
priv->fname && strcmp(p->fname, priv->fname))
free_firmware(priv);
where priv->fname points to the previous file name, and this was
already freed by kfree().
For fixing the bug properly, this patch does the following:
- Keep the copy of firmware file name in only priv->fname,
priv->ctrl.fname isn't changed;
- The allocation is done only when the firmware gets loaded;
- The kfree() is called in free_firmware() commonly

Signed-off-by: Stephen Boyd <sboyd@codeaurora.org>
Per PCIe spec r3.0, sec 2.3.1.1, the Read Completion Boundary (RCB)
determines the naturally aligned address boundaries on which a Read Request
may be serviced with multiple Completions:
- For a Root Complex, RCB is 64 bytes or 128 bytes
This value is reported in the Link Control Register
Note: Bridges and Endpoints may implement a corresponding command bit
which may be set by system software to indicate the RCB value for the
Root Complex, allowing the Bridge/Endpoint to optimize its behavior
when the Root Complex’s RCB is 128 bytes.
- For all other system elements, RCB is 128 bytes
Per sec 7.8.7, if a Root Port only supports a 64-byte RCB, the RCB of all
downstream devices must be clear, indicating an RCB of 64 bytes. If the
Root Port supports a 128-byte RCB, we may optionally set the RCB of
downstream devices so they know they can generate larger Completions.
Some BIOSes supply an _HPX that tells us to set RCB, even though the Root
Port doesn't have RCB set, which may lead to Malformed TLP errors if the
Endpoint generates completions larger than the Root Port can handle.
The IBM x3850 X6 with BIOS version -[A8E120CUS-1.30]- 08/22/2016 supplies
such an _HPX and a Mellanox MT27500 ConnectX-3 device fails to initialize:
mlx4_core 0000:41:00.0: command 0xfff timed out (go bit not cleared)
mlx4_core 0000:41:00.0: device is going to be reset
mlx4_core 0000:41:00.0: Failed to obtain HW semaphore, aborting
mlx4_core 0000:41:00.0: Fail to reset HCA
------------[ cut here ]------------
kernel BUG at drivers/net/ethernet/mellanox/mlx4/catas.c:193!
After 6cd33649fa ("PCI: Add pci_configure_device() during enumeration")
and 7a1562d4f2 ("PCI: Apply _HPX Link Control settings to all devices
with a link"), we apply _HPX settings to *all* devices, not just those
hot-added after boot.
Before 7a1562d4f2, we didn't touch the Mellanox RCB, and the device
worked. After 7a1562d4f2, we set its RCB to 128, and it failed.
Set the RCB to 128 iff the Root Port supports a 128-byte RCB. Otherwise,
set RCB to 64 bytes. This effectively ignores what _HPX tells us about
RCB.
Note that this change only affects _HPX handling. If we have no _HPX, this
does nothing with RCB.

tile: avoid using clocksource_cyc2ns with absolute cycle count
In the user manual of A33 SoC, the bit 22 and 23 of pll-mipi control
register is called "LDO{1,2}_EN", and according to the BSP source code
from Allwinner [1], the LDOs are enabled during the clock's enabling
process.
The clock failed to generate output if the two LDOs are not enabled.
Add the two bits to the clock's gate bits, so that the LDOs are enabled
when the PLL is enabled.

For large values of "mult" and long uptimes, the intermediate
result of "cycles * mult" can overflow 64 bits. For example,
the tile platform calls clocksource_cyc2ns with a 1.2 GHz clock;
we have mult = 853, and after 208.5 days, we overflow 64 bits.
Since clocksource_cyc2ns() is intended to be used for relative
cycle counts, not absolute cycle counts, performance is more
importance than accepting a wider range of cycle values. So,
just use mult_frac() directly in tile's sched_clock().
Commit 4cecf6d401 ("sched, x86: Avoid unnecessary overflow
in sched_clock") by Salman Qazi results in essentially the same
generated code for x86 as this change does for tile. In fact,
a follow-on change by Salman introduced mult_frac() and switched
to using it, so the C code was largely identical at that point too.
Peter Zijlstra then added mul_u64_u32_shr() and switched x86
to use it. This is, in principle, better; by optimizing the
64x64->64 multiplies to be 32x32->64 multiplies we can potentially
save some time. However, the compiler piplines the 64x64->64
multiplies pretty well, and the conditional branch in the generic
mul_u64_u32_shr() causes some bubbles in execution, with the
result that it's pretty much a wash. If tilegx provided its own
implementation of mul_u64_u32_shr() without the conditional branch,
we could potentially save 3 cycles, but that seems like small gain
for a fair amount of additional build scaffolding; no other platform
currently provides a mul_u64_u32_shr() override, and tile doesn't
currently have an <asm/div64.h> header to put the override in.
Additionally, gcc currently has an optimization bug that prevents
it from recognizing the opportunity to use a 32x32->64 multiply,
and so the result would be no better than the existing mult_frac()
until such time as the compiler is fixed.
For now, just using mult_frac() seems like the right answer.

When PCIe port PM is not enabled (system BIOS is pre-2015 or the
pcie_port_pm=off parameter is set), legacy ATPX PM should still be
marked as supported. Otherwise the GPU can fail to power on after
runtime suspend. This affected a Dell Inspiron 5548.
Ideally the BIOS date in the PCI core is lowered to 2013 (the first year
where hybrid graphics platforms using power resources was introduced),
but that seems more risky at this point and would not solve the
pcie_port_pm=off issue.
