KVM: s390: do not expose random data via facility bitmap

kvm_s390_get_machine() populates the facility bitmap by copying bytes
from the host results that are stored in a 256 byte array in the prefix
page. The KVM code does use the size of the target buffer (2k), thus
copying and exposing unrelated kernel memory (mostly machine check
related logout data).

Let's use the size of the source buffer instead.  This is ok, as the
target buffer will always be greater or equal than the source buffer as
the KVM internal buffers (and thus S390_ARCH_FAC_LIST_SIZE_BYTE) cover
the maximum possible size that is allowed by STFLE, which is 256
doublewords. All structures are zero allocated so we can leave bytes
256-2047 unchanged.

According to the datasheet for the M25P64 part present on the da850-evm,
if the SPI frequency is higher than 20MHz then the READ command is not

Mark Rutland [Wed, 18 Jan 2017 17:23:41 +0000 (17:23 +0000)]
arm64: avoid returning from bad_mode

Generally, taking an unexpected exception should be a fatal event, and
bad_mode is intended to cater for this. However, it should be possible
to contain unexpected synchronous exceptions from EL0 without bringing
the kernel down, by sending a SIGILL to the task.

We tried to apply this approach in commit 9955ac47f4ba1c95 ("arm64:
don't kill the kernel on a bad esr from el0"), by sending a signal for
any bad_mode call resulting from an EL0 exception.

However, this also applies to other unexpected exceptions, such as
SError and FIQ. The entry paths for these exceptions branch to bad_mode
without configuring the link register, and have no kernel_exit. Thus, if
we take one of these exceptions from EL0, bad_mode will eventually
return to the original user link register value.

This patch fixes this by introducing a new bad_el0_sync handler to cater
for the recoverable case, and restoring bad_mode to its original state,
whereby it calls panic() and never returns. The recoverable case
branches to bad_el0_sync with a bl, and returns to userspace via the
usual ret_to_user mechanism.

Jason Gerecke [Tue, 17 Jan 2017 23:38:58 +0000 (15:38 -0800)]
HID: wacom: Fix sibling detection regression

Commit 345857b ("HID: wacom: generic: Add support for sensor offsets") included
a change to the operation and location of the call to 'wacom_add_shared_data'
in 'wacom_parse_and_register'. The modifications included moving it higher up
so that it would occur before the call to 'wacom_retrieve_hid_descriptor'. This
was done to prevent a crash that would have occured when the report containing
tablet offsets was fed into the driver with 'wacom_hid_report_raw_event'
(specifically: the various 'wacom_wac_*_report' functions were written with the
assumption that they would only be called once tablet setup had completed;
'wacom_wac_pen_report' in particular dereferences 'shared' which wasn't yet
allocated).

Moving the call to 'wacom_add_shared_data' effectively prevented the crash but
also broke the sibiling detection code which assumes that the HID descriptor
has been read and the various device_type flags set.

To fix this situation, we restore the original 'wacom_add_shared_data'
operation and location and instead implement an alternative change that can
also prevent the crash. Specifically, we notice that the report functions
mentioned above expect to be called only for input reports.  By adding a check,
we can prevent feature reports (such as the offset report) from
causing trouble.

ARM64: dts: meson-gxbb-odroidc2: Disable SCPI DVFS

The current hardware is not able to run with all cores enabled at a
cluster frequency superior at 1536MHz.
But the currently shipped u-boot for the platform still reports an OPP
table with possible DVFS frequency up to 2GHz, and will not change since
the off-tree linux tree supports limiting the OPPs with a kernel parameter.
A recent u-boot change reports the boot-time DVFS around 100MHz and
the default performance cpufreq governor sets the maximum frequency.
Previous version of u-boot reported to be already at the max OPP and
left the OPP as is.
Nevertheless, other governors like ondemand could setup the max frequency
and make the system crash.

This patch disables the DVFS clock and disables cpufreq.

ubifs: Fix journal replay wrt. xattr nodes

When replaying the journal it can happen that a journal entry points to
a garbage collected node.
This is the case when a power-cut occurred between a garbage collect run
and a commit. In such a case nodes have to be read using the failable
read functions to detect whether the found node matches what we expect.

One corner case was forgotten, when the journal contains an entry to
remove an inode all xattrs have to be removed too. UBIFS models xattr
like directory entries, so the TNC code iterates over
all xattrs of the inode and removes them too. This code re-uses the
functions for walking directories and calls ubifs_tnc_next_ent().
ubifs_tnc_next_ent() expects to be used only after the journal and
aborts when a node does not match the expected result. This behavior can
render an UBIFS volume unmountable after a power-cut when xattrs are
used.

Fix this issue by using failable read functions in ubifs_tnc_next_ent()
too when replaying the journal.

Alexander Graf [Mon, 16 Jan 2017 11:46:33 +0000 (12:46 +0100)]
arm64: Fix swiotlb fallback allocation

Commit b67a8b29df introduced logic to skip swiotlb allocation when all memory
is DMA accessible anyway.

While this is a great idea, __dma_alloc still calls swiotlb code unconditionally
to allocate memory when there is no CMA memory available. The swiotlb code is
called to ensure that we at least try get_free_pages().

Without initialization, swiotlb allocation code tries to access io_tlb_list
which is NULL. That results in a stack trace like this:

  Unable to handle kernel NULL pointer dereference at virtual address 00000000
  [...]
  [<ffff00000845b908>] swiotlb_tbl_map_single+0xd0/0x2b0

  [<ffff000000b46a94>] vc4_drm_bind+0xec/0x168 [vc4]
  [...]

Thankfully swiotlb code just learned how to not do allocations with the FORCE_NO
option. This patch configures the swiotlb code to use that if we decide not to
initialize the swiotlb framework.

perf/x86/intel: Handle exclusive threadid correctly on CPU hotplug

The CPU hotplug function intel_pmu_cpu_starting() sets
cpu_hw_events.excl_thread_id unconditionally to 1 when the shared exclusive
counters data structure is already availabe for the sibling thread.

This works during the boot process because the first sibling gets threadid
0 assigned and the second sibling which shares the data structure gets 1.

But when the first thread of the core is offlined and onlined again it
shares the data structure with the second thread and gets exclusive thread
id 1 assigned as well.

Prevent this by checking the threadid of the already online thread.
