MIPS: AR7: ensure the port type's FCR value is used
commit
0a5191efe06b5103909206e4fbcff81d30283f8e upstream.
Since commit
aef9a7bd9b67 ("serial/uart/8250: Add tunable RX interrupt
trigger I/F of FIFO buffers"), the port's default FCR value isn't used
in serial8250_do_set_termios anymore, but copied over once in
serial8250_config_port and then modified as needed.
Unfortunately, serial8250_config_port will never be called if the port
is shared between kernel and userspace, and the port's flag doesn't have
UPF_BOOT_AUTOCONF, which would trigger a serial8250_config_port as well.
This causes garbled output from userspace:
[ 5.220000] random: procd urandom read with 49 bits of entropy available
ers
[kee
Fix this by forcing it to be configured on boot, resulting in the
expected output:
[ 5.250000] random: procd urandom read with 50 bits of entropy available

x86/retpoline: Optimize inline assembler for vmexit_fill_RSB
commit
3f7d875566d8e79c5e0b2c9a413e91b2c29e0854 upstream.
The generated assembler for the C fill RSB inline asm operations has
several issues:
- The C code sets up the loop register, which is then immediately
overwritten in __FILL_RETURN_BUFFER with the same value again.
- The C code also passes in the iteration count in another register, which
is not used at all.
Remove these two unnecessary operations. Just rely on the single constant
passed to the macro for the iterations.

kprobes/x86: Disable optimizing on the function jumps to indirect thunk
commit
c86a32c09f8ced67971a2310e3b0dda4d1749007 upstream.
Since indirect jump instructions will be replaced by jump
to __x86_indirect_thunk_*, those jmp instruction must be
treated as an indirect jump. Since optprobe prohibits to
optimize probes in the function which uses an indirect jump,
it also needs to find out the function which jump to
__x86_indirect_thunk_* and disable optimization.
Add a check that the jump target address is between the
__indirect_thunk_start/end when optimizing kprobe.

Introduce start/end markers of __x86_indirect_thunk_* functions.
To make it easy, consolidate .text.__x86.indirect_thunk.* sections
to one .text.__x86.indirect_thunk section and put it in the
end of kernel text section and adds __indirect_thunk_start/end
so that other subsystem (e.g. kprobes) can identify it.

The machine check idtentry uses an indirect branch directly from the low

Replace it by a direct call into C code and issue the indirect call there

x86/cpu, x86/pti: Do not enable PTI on AMD processors
commit

AMD processors are not subject to the types of attacks that the kernel
page table isolation feature protects against. The AMD microarchitecture
does not allow memory references, including speculative references, that
access higher privileged data when running in a lesser privileged mode
when that access would result in a page fault.
Disable page table isolation by default on AMD processors by not setting
the X86_BUG_CPU_INSECURE feature, which controls whether X86_FEATURE_PTI
is set.

KVM doesn't follow the SMCCC when it comes to unimplemented calls,
and inject an UNDEF instead of returning an error. Since firmware
calls are now used for security mitigation, they are becoming more
common, and the undef is counter productive.
Instead, let's follow the SMCCC which states that -1 must be returned
to the caller when getting an unknown function number.

dm thin metadata: THIN_MAX_CONCURRENT_LOCKS should be 6
commit
490ae017f54e55bde382d45ea24bddfb6d1a0aaf upstream.
For btree removal, there is a corner case that a single thread
could takes 6 locks which is more than THIN_MAX_CONCURRENT_LOCKS(5)
and leads to deadlock.
A btree removal might eventually call
rebalance_children()->rebalance3() to rebalance entries of three
neighbor child nodes when shadow_spine has already acquired two
write locks. In rebalance3(), it tries to shadow and acquire the
write locks of all three child nodes. However, shadowing a child
node requires acquiring a read lock of the original child node and
a write lock of the new block. Although the read lock will be
released after block shadowing, shadowing the third child node
in rebalance3() could still take the sixth lock.
(2 write locks for shadow_spine +
2 write locks for the first two child nodes's shadow +
1 write lock for the last child node's shadow +
1 read lock for the last child node)

dm btree: fix serious bug in btree_split_beneath()
commit
bc68d0a43560e950850fc69b58f0f8254b28f6d6 upstream.
When inserting a new key/value pair into a btree we walk down the spine of
btree nodes performing the following 2 operations:
i) space for a new entry
ii) adjusting the first key entry if the new key is lower than any in the node.
If the _root_ node is full, the function btree_split_beneath() allocates 2 new
nodes, and redistibutes the root nodes entries between them. The root node is
left with 2 entries corresponding to the 2 new nodes.
btree_split_beneath() then adjusts the spine to point to one of the two new
children. This means the first key is never adjusted if the new key was lower,
ie. operation (ii) gets missed out. This can result in the new key being
'lost' for a period; until another low valued key is inserted that will uncover
it.
This is a serious bug, and quite hard to make trigger in normal use. A
reproducing test case ("thin create devices-in-reverse-order") is
available as part of the thin-provision-tools project:
https://github.com/jthornber/thin-provisioning-tools/blob/master/functional-tests/device-mapper/dm-tests.scm#L593
Fix the issue by changing btree_split_beneath() so it no longer adjusts
the spine. Instead it unlocks both the new nodes, and lets the main
loop in btree_insert_raw() relock the appropriate one and make any
neccessary adjustments.

ARM: dts: kirkwood: fix pin-muxing of MPP7 on OpenBlocks A7
commit
56aeb07c914a616ab84357d34f8414a69b140cdf upstream.
MPP7 is currently muxed as "gpio", but this function doesn't exist for
MPP7, only "gpo" is available. This causes the following error:
kirkwood-pinctrl
f1010000.pin-controller: unsupported function gpio on pin mpp7
pinctrl core: failed to register map default (6): invalid type given
kirkwood-pinctrl
f1010000.pin-controller: error claiming hogs: -22
kirkwood-pinctrl
f1010000.pin-controller: could not claim hogs: -22
kirkwood-pinctrl
f1010000.pin-controller: unable to register pinctrl driver
kirkwood-pinctrl: probe of
f1010000.pin-controller failed with error -22
So the pinctrl driver is not probed, all device drivers (including the
UART driver) do a -EPROBE_DEFER, and therefore the system doesn't
really boot (well, it boots, but with no UART, and no devices that
require pin-muxing).
Back when the Device Tree file for this board was introduced, the
definition was already wrong. The pinctrl driver also always described
as "gpo" this function for MPP7. However, between Linux 4.10 and 4.11,
a hog pin failing to be muxed was turned from a simple warning to a
hard error that caused the entire pinctrl driver probe to bail
out. This is probably the result of commit
6118714275f0a ("pinctrl:
core: Fix pinctrl_register_and_init() with pinctrl_enable()").
This commit fixes the Device Tree to use the proper "gpo" function for
MPP7, which fixes the boot of OpenBlocks A7, which was broken since
Linux 4.11.

phy: work around 'phys' references to usb-nop-xceiv devices
commit
b7563e2796f8b23c98afcfea7363194227fa089d upstream.
Stefan Wahren reports a problem with a warning fix that was merged
for v4.15: we had lots of device nodes with a 'phys' property pointing
to a device node that is not compliant with the binding documented in
Documentation/devicetree/bindings/phy/phy-bindings.txt
This generally works because USB HCD drivers that support both the generic
phy subsystem and the older usb-phy subsystem ignore most errors from
phy_get() and related calls and then use the usb-phy driver instead.
However, it turns out that making the usb-nop-xceiv device compatible with
the generic-phy binding changes the phy_get() return code from -EINVAL to
-EPROBE_DEFER, and the dwc2 usb controller driver for bcm2835 now returns
-EPROBE_DEFER from its probe function rather than ignoring the failure,
breaking all USB support on raspberry-pi when CONFIG_GENERIC_PHY is
enabled. The same code is used in the dwc3 driver and the usb_add_hcd()
function, so a reasonable assumption would be that many other platforms
are affected as well.
I have reviewed all the related patches and concluded that "usb-nop-xceiv"
is the only USB phy that is affected by the change, and since it is by far
the most commonly referenced phy, all the other USB phy drivers appear
to be used in ways that are are either safe in DT (they don't use the
'phys' property), or in the driver (they already ignore -EPROBE_DEFER
from generic-phy when usb-phy is available).
To work around the problem, this adds a special case to _of_phy_get()
so we ignore any PHY node that is compatible with "usb-nop-xceiv",
as we know that this can never load no matter how much we defer. In the
future, we might implement a generic-phy driver for "usb-nop-xceiv"
and then remove this workaround.
Since we generally want older kernels to also want to work with the
fixed devicetree files, it would be good to backport the patch into
stable kernels as well (3.13+ are possibly affected), even though they
don't contain any of the patches that may have caused regressions.
