[ Upstream commit 7d5fff8982a2199d49ec067818af7d84d4f95ca0 ]
__md_stop_writes() and __md_stop() will modify many fields that are
protected by 'reconfig_mutex', and all the callers will grab
'reconfig_mutex' except for md_stop().
Also, update md_stop() to make certain 'reconfig_mutex' is held using
lockdep_assert_held().

introduced a new struct mthca_sqp which doesn't contain struct mthca_qp

[ Upstream commit 6c58c8816abb7b93b21fa3b1d0c1726402e5e568 ]
The nla_for_each_nested parsing in function mqprio_parse_nlattr() does
not check the length of the nested attribute. This can lead to an
out-of-attribute read and allow a malformed nlattr (e.g., length 0) to
be viewed as 8 byte integer and passed to priv->max_rate/min_rate.
This patch adds the check based on nla_len() when check the nla_type(),
which ensures that the length of these two attribute must equals
sizeof(u64).

The lazy gc on insert that should remove timed-out entries fails to release
the other half of the interval, if any.
Can be reproduced with tests/shell/testcases/sets/0044interval_overlap_0
in nftables.git and kmemleak enabled kernel.
Second bug is the use of rbe_prev vs. prev pointer.
If rbe_prev() returns NULL after at least one iteration, rbe_prev points
to element that is not an end interval, hence it should not be removed.
Lastly, check the genmask of the end interval if this is active in the
current generation.

[ Upstream commit ad084a6d99bc182bf109c190c808e2ea073ec57b ]
Only the HW rfkill state is toggled on laptops with quirks->ec_read_only
(so far only MSI Wind U90/U100). There are, however, a few issues with
the implementation:
1. The initial HW state is always unblocked, regardless of the actual
state on boot, because msi_init_rfkill only sets the SW state,
regardless of ec_read_only.
2. The initial SW state corresponds to the actual state on boot, but it
can't be changed afterwards, because set_device_state returns
-EOPNOTSUPP. It confuses the userspace, making Wi-Fi and/or Bluetooth
unusable if it was blocked on boot, and breaking the airplane mode if
the rfkill was unblocked on boot.
Address the above issues by properly initializing the HW state on
ec_read_only laptops and by allowing the userspace to toggle the SW
state. Don't set the SW state ourselves and let the userspace fully
control it. Toggling the SW state is a no-op, however, it allows the
userspace to properly toggle the airplane mode. The actual SW radio
disablement is handled by the corresponding rtl818x_pci and btusb
drivers that have their own rfkills.
Tested on MSI Wind U100 Plus, BIOS ver 1.0G, EC ver 130.

[ Upstream commit d11b0df7ddf1831f3e170972f43186dad520bfcc ]
For both IPv4 and IPv6 incoming TCP connections are tracked in a hash
table with a hash over the source & destination addresses and ports.
However, the IPv6 hash is insufficient and can lead to a high rate of
collisions.
The IPv6 hash used an XOR to fit everything into the 96 bits for the
fast jenkins hash, meaning it is possible for an external entity to
ensure the hash collides, thus falling back to a linear search in the
bucket, which is slow.
We take the approach of hash the full length of IPv6 address in
__ipv6_addr_jhash() so that all users can benefit from a more secure
version.
While this may look like it adds overhead, the reality of modern CPUs
means that this is unmeasurable in real world scenarios.
In simulating with llvm-mca, the increase in cycles for the hashing
code was ~16 cycles on Skylake (from a base of ~155), and an extra ~9
on Nehalem (base of ~173).
In commit dd6d2910c5e0 ("netfilter: conntrack: switch to siphash")
netfilter switched from a jenkins hash to a siphash, but even the faster
hsiphash is a more significant overhead (~20-30%) in some preliminary
testing. So, in this patch, we keep to the more conservative approach to
ensure we don't add much overhead per SYN.
In testing, this results in a consistently even spread across the
connection buckets. In both testing and real-world scenarios, we have
not found any measurable performance impact.

[ Upstream commit 94d166c5318c6edd1e079df8552233443e909c33 ]
VXLAN-GPE does not add an extra inner Ethernet header. Take that into
account when calculating header length.
This causes problems in skb_tunnel_check_pmtu, where incorrect PMTU is
cached.
In the collect_md mode (which is the only mode that VXLAN-GPE
supports), there's no magic auto-setting of the tunnel interface MTU.
It can't be, since the destination and thus the underlying interface
may be different for each packet.
So, the administrator is responsible for setting the correct tunnel
interface MTU. Apparently, the administrators are capable enough to
calculate that the maximum MTU for VXLAN-GPE is (their_lower_MTU - 36).
They set the tunnel interface MTU to 1464. If you run a TCP stream over
such interface, it's then segmented according to the MTU 1464, i.e.
producing 1514 bytes frames. Which is okay, this still fits the lower
MTU.
However, skb_tunnel_check_pmtu (called from vxlan_xmit_one) uses 50 as
the header size and thus incorrectly calculates the frame size to be
1528. This leads to ICMP too big message being generated (locally),
PMTU of 1450 to be cached and the TCP stream to be resegmented.
The fix is to use the correct actual header size, especially for
skb_tunnel_check_pmtu calculation.

[ Upstream commit 8a0eb8f9b9a002291a3934acfd913660b905249e ]
The driver is not enabling the ref clock, which thus gets disabled by
the clk_disable_unused() initcall. This leads to the dwc3 controller
failing to initialize if probed after clk_disable_unused() is called,
for instance when the driver is built as a module.
To fix this, switch to the clk_bulk API to handle both cfg_ahb and ref
clocks at the proper places.
Note that the cfg_ahb clock is currently not used by any device tree
instantiation of the PHY. Work needs to be done separately to fix this.

[ Upstream commit 45d89a344eb46db9dce851c28e14f5e3c635c251 ]
In the dwc3 core, both system and runtime suspend end up calling
dwc3_suspend_common(). From there, what happens for the PHYs depends on
the USB mode and whether the controller is entering system or runtime
suspend.
HOST mode:
(1) system suspend on a non-wakeup-capable controller
The [1] if branch is taken. dwc3_core_exit() is called, which ends up
calling phy_power_off() and phy_exit(). Those two functions decrease the
PM runtime count at some point, so they will trigger the PHY runtime
sleep (assuming the count is right).
(2) runtime suspend / system suspend on a wakeup-capable controller
The [1] branch is not taken. dwc3_suspend_common() calls
phy_pm_runtime_put_sync(). Assuming the ref count is right, the PHY
runtime suspend op is called.
DEVICE mode:
dwc3_core_exit() is called on both runtime and system sleep
unless the controller is already runtime suspended.
OTG mode:
(1) system suspend : dwc3_core_exit() is called
(2) runtime suspend : do nothing
In host mode, the code seems to make a distinction between 1) runtime
sleep / system sleep for wakeup-capable controller, and 2) system sleep
for non-wakeup-capable controller, where phy_power_off() and phy_exit()
are only called for the latter. This suggests the PHY is not supposed to
be in a fully powered-off state for runtime sleep and system sleep for
wakeup-capable controller.
Moreover, downstream, cfg_ahb_clk only gets disabled for system suspend.
The clocks are disabled by phy->set_suspend() [2] which is only called
in the system sleep path through dwc3_core_exit() [3].
With that in mind, don't disable the clocks during the femto PHY runtime
suspend callback. The clocks will only be disabled during system suspend
for non-wakeup-capable controllers, through dwc3_core_exit().

[ Upstream commit efbbdaa22bb78761bff8dfdde027ad04bedd47ce ]
To help debugging kernel, show real address for trace event arguments
in tracefs/trace{,pipe} instead of hashed pointer value.
Since ftrace human-readable format uses vsprintf(), all %p are
translated to hash values instead of pointer address.
However, when debugging the kernel, raw address value gives a
hint when comparing with the memory mapping in the kernel.
(Those are sometimes used with crash log, which is not hashed too)
So converting %p with %px when calling trace_seq_printf().
Moreover, this is not improving the security because the tracefs
can be used only by root user and the raw address values are readable
from tracefs/percpu/cpu*/trace_pipe_raw file.
