Operating mode determines the support for other protocols.
This is made as module parameter for better usage.

BT frames are passed through coex and hal modules to BUS.
After firmware is loaded, based on the operating mode CARD
READY frame comes for each protocol. When BT card ready is
received, BT attach is called.
Protocol operations are exchanged between the modules
at initialization time.
Build flag CONFIG_RSI_COEX is introduced to enable coex support
if CONFIG_BT_RSIHCI is enabled. Coex operations are valid if
coex mode is greater than 1 only.

Redpine bluetooth driver is a thin driver which depends on
'rsi_91x' driver for transmitting and receiving packets
to/from device. It creates hci interface when attach() is
called from 'rsi_91x' module.

With BT support, driver has to handle two streams of data
(i.e. wlan and BT). Actual coex implementation is in firmware.
Coex module just schedule the packets to firmware by taking them
from the corresponding paths.
Structures for module and protocol operations are introduced for
this purpose. Protocol operations structure is global structure
which can be shared among different modules. Move initialization
of coex and operating mode values to rsi_91x_init().

Apparently the hardware does not perform CCMP PN validation so
let mac80211 take care of possible replay attacks in sw.
Moreover indicate ICV and MIC had been stripped setting corresponding
bits in ieee80211_rx_status.
The fix has been validated using 4.2.1 and 4.1.3 tests from the WiFi

1) Refuse to insert 32 bit userspace socket policies on 64
bit systems like we do it for standard policies. We don't
have a compat layer, so inserting socket policies from
32 bit userspace will lead to a broken configuration.
2) Make the policy hold queue work without the flowcache.
Dummy bundles are not chached anymore, so we need to
generate a new one on each lookup as long as the SAs
are not yet in place.
3) Fix the validation of the esn replay attribute. The
The sanity check in verify_replay() is bypassed if
the XFRM_STATE_ESN flag is not set. Fix this by doing
the sanity check uncoditionally.
From Florian Westphal.
4) After most of the dst_entry garbage collection code
is removed, we may leak xfrm_dst entries as they are
neither cached nor tracked somewhere. Fix this by
reusing the 'uncached_list' to track xfrm_dst entries
too. From Xin Long.
5) Fix a rcu_read_lock/rcu_read_unlock imbalance in
xfrm_get_tos() From Xin Long.
6) Fix an infinite loop in xfrm_get_dst_nexthop. On
transport mode we fetch the child dst_entry after

Fix this by fetching it before we continue.
7) Fix ESN sequence number gap after IPsec GSO packets.
We accidentally increment the sequence number counter
on the xfrm_state by one packet too much in the ESN
case. Fix this by setting the sequence number to the
correct value.
8) Reset the ethernet protocol after decapsulation only if a

As reported by Jeremy Cline, running the new TPM libstub code in mixed
mode (i.e., 64-bit kernel on 32-bit UEFI) results in hangs when invoking
the TCG2 protocol, or when accessing the log_tbl pool allocation.
The reason turns out to be that in both cases, the 64-bit pointer
variables are not fully initialized by the 32-bit EFI code, and so
we should take care to zero initialize these variables beforehand,
or we'll end up dereferencing bogus pointers.

ibmvnic: Fix VLAN and other device errata
This patch series contains fixes for VLAN and other backing hardware
errata. The VLAN fixes are mostly to account for the additional four
bytes VLAN header in TX descriptors and buffers, when applicable.
The other fixes for device errata are to pad small packets to avoid a
possible connection error that can occur when some devices attempt to
transmit small packets. The other fixes are GSO related. Some devices
cannot handle a smaller MSS or a packet with a single segment, so
disable GSO in those cases.

f7c83bcbfaf5 ("net: xfrm: use __this_cpu_read per-cpu helper") added a
__this_cpu_read() call inside ipcomp_alloc_tfms().
At the time, __this_cpu_read() required the caller to either not care
about races or to handle preemption/interrupt issues. 3.15 tightened
the rules around some per-cpu operations, and now __this_cpu_read()
should never be used in a preemptible context. On 3.15 and later, we
need to use this_cpu_read() instead.
syzkaller reported this leading to the following kernel BUG while

discovery this resulted into only discovering NVMe LUNs.

During the conversion to dsa_is_user_port(), a condition ended up being
reversed, which would prevent the creation of any user port when using
the legacy binding and/or platform data, fix that.

Currently the link state is initialized to "up" when the phy_device is
being created. This is not consistent with the phy state being
initialized to PHY_DOWN.
Usually this doen't do any harm because the link state is updated
once the PHY reaches state PHY_AN. However e.g. if a LAN port isn't
used and the PHY remains down this inconsistency remains and calls
to functions like phy_print_status() give false results.
Therefore change the initialization to link being down.

In case of error, the function dev_get_regmap() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check should be
replaced with NULL test.

* 'clk-helpers' (early part):
clk: fix determine rate error with pass-through clock
|
|
If we try to determine the rate of a pass-through clock (a clock which
does not implement .round_rate() nor .determine_rate()),
clk_core_round_rate_nolock() will directly forward the call to the
parent clock. In the particular case where the pass-through actually
does not have a parent, clk_core_round_rate_nolock() will directly
return 0 with the requested rate still set to the initial request
structure. This is interpreted as if the rate could be exactly achieved
while it actually cannot be adjusted.
This become a real problem when this particular pass-through clock is
the parent of a mux with the flag CLK_SET_RATE_PARENT set. The
pass-through clock will always report an exact match, get picked and
finally error when the rate is actually getting set.
This is fixed by setting the rate inside the req to 0 when core is NULL
in clk_core_round_rate_nolock() (same as in __clk_determine_rate() when
hw is NULL)
Fixes: 0f6cc2b8e94d ("clk: rework calls to round and determine rate callbacks")

Pull Allwinner clock fixes for 4.16 from Chen-Yu Tsai:
A critical fix for the A31 sunxi-ng clock driver. The CLK_OUT clocks
had definitions paired with the incorrect type of clk ops. This results
in a serious oops starting with commit 946797aa3f08 ("clk: sunxi-ng:
Support fixed post-dividers on MP style clocks"), which exposed the
incorrect clk ops when it added a new field to the data structures,
which then nudged the underlying (compatible but incorrect) data
structures out of alignment.

Jeff Kirsher says:
====================
10GbE Intel Wired LAN Driver Updates 2018-03-12
This series contains updates to ixgbe and ixgbevf only.
Shannon Nelson provides three fixes to the ipsec portion of ixgbe. Make
sure we are using 128-bit authentication, since it is the only size
supported for hardware offload. Fixed the transmit trailer length
calculation for ipsec by finding the padding value and adding it to the
authentication length, then save it off so that we can put it in the
transmit descriptor to tell the device where to stop the checksum
calculation. Lastly, cleaned up useless and dead code.
Tonghao Zhang adds a ethtool stat for receive length errors, since the
driver was already collecting this counter.
Arnd Bergmann fixed a warning about an used variable by "rephrasing" the
code so that the compiler can see the use of the variable in question.
Paul fixes an issue where "HIDE_VLAN" was being cleared on VF reset, so
ensure to set "HIDE_VLAN" when port VLAN is enabled after a VF reset.
