From: Cyril Bur <cyrilbur@gmail.com>
commit 8e96a87c5431c256feb65bcfc5aec92d9f7839b6 upstream.
Userspace can quite legitimately perform an exec() syscall with a
suspended transaction. exec() does not return to the old process, rather
it load a new one and starts that, the expectation therefore is that the
new process starts not in a transaction. Currently exec() is not treated
any differently to any other syscall which creates problems.
Firstly it could allow a new process to start with a suspended
transaction for a binary that no longer exists. This means that the
checkpointed state won't be valid and if the suspended transaction were
ever to be resumed and subsequently aborted (a possibility which is
exceedingly likely as exec()ing will likely doom the transaction) the
new process will jump to invalid state.
Secondly the incorrect attempt to keep the transactional state while
still zeroing state for the new process creates at least two TM Bad
Things. The first triggers on the rfid to return to userspace as
start_thread() has given the new process a 'clean' MSR but the suspend
will still be set in the hardware MSR. The second TM Bad Thing triggers
in __switch_to() as the processor is still transactionally suspended but
__switch_to() wants to zero the TM sprs for the new process.
This is an example of the outcome of calling exec() with a suspended
transaction. Note the first 700 is likely the first TM bad thing
decsribed earlier only the kernel can't report it as we've loaded
userspace registers. c000000000009980 is the rfid in
fast_exception_return()

| Message-ID | <rYWHw-2cA-23@gated-at.bofh.it> |
| In reply to | #1450166 |
4.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Guilherme G. Piccoli <gpiccoli@linux.vnet.ibm.com>
commit 8445a87f7092bc8336ea1305be9306f26b846d93 upstream.
Commit 39baadbf36ce ("powerpc/eeh: Remove eeh information from pci_dn")
changed the pci_dn struct by removing its EEH-related members.
As part of this clean-up, DDW mechanism was modified to read the device
configuration address from eeh_dev struct.
As a consequence, now if we disable EEH mechanism on kernel command-line
for example, the DDW mechanism will fail, generating a kernel oops by
dereferencing a NULL pointer (which turns to be the eeh_dev pointer).
This patch just changes the configuration address calculation on DDW
functions to a manual calculation based on pci_dn members instead of
using eeh_dev-based address.

From: Eric W. Biederman <ebiederm@xmission.com>
commit 695e9df010e40f407f4830dc11d53dce957710ba upstream.
In rare cases it is possible for s_flags & MS_RDONLY to be set but
MNT_READONLY to be clear. This starting combination can cause
fs_fully_visible to fail to ensure that the new mount is readonly.
Therefore force MNT_LOCK_READONLY in the new mount if MS_RDONLY
is set on the source filesystem of the mount.
In general both MS_RDONLY and MNT_READONLY are set at the same for
mounts so I don't expect any programs to care. Nor do I expect
MS_RDONLY to be set on proc or sysfs in the initial user namespace,
which further decreases the likelyhood of problems.
Which means this change should only affect system configurations by
paranoid sysadmins who should welcome the additional protection
as it keeps people from wriggling out of their policies.

commit d71ed6c930ac7d8f88f3cef6624a7e826392d61f upstream.
MNT_LOCKED implies on a child mount implies the child is locked to the
parent. So while looping through the children the children should be
tested (not their parent).
Typically an unshare of a mount namespace locks all mounts together
making both the parent and the slave as locked but there are a few
corner cases where other things work.

commit 47355b3cd7d3c9c5226bff7c449b9d269fb17fa6 upstream.
ib_device_cap_flags 64-bit expansion caused caps overlapping
and made consumers read wrong device capabilities. For example
IB_DEVICE_SG_GAPS_REG was falsely read by the iser driver causing
it to use a non-existing capability. This happened because signed
int becomes sign extended when converted it to u64. Fix this by
casting IB_DEVICE_ON_DEMAND_PAGING enumeration to ULL.

| Message-ID | <rYWHw-2cA-37@gated-at.bofh.it> |
| In reply to | #1450166 |
4.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
commit 23e3439296a55affce3ef0ab78f1c2e03aec8767 upstream.
A patch that went into Linux-4.4 to fix big-endian mode on a Lantiq
MIPS system unfortunately broke big-endian operation on PowerPC
APM82181 as reported by Christian Lamparter, and likely other
systems.
It actually introduced multiple issues:
- it broke big-endian ARM kernels: any machine that was working
correctly with a little-endian kernel is no longer using byteswaps
on big-endian kernels, which clearly breaks them.
- On PowerPC the same thing must be true: if it was working before,
using big-endian kernels is now broken. Unlike ARM, 32-bit PowerPC
usually uses big-endian kernels, so they are likely all broken.
- The barrier for dwc2_writel is on the wrong side of the __raw_writel(),
so the MMIO no longer synchronizes with DMA operations.
- On architectures that require specific CPU instructions for MMIO
access, using the __raw_ variant may turn this into a pointer
dereference that does not have the same effect as the readl/writel.
This patch is a simple revert for all architectures other than MIPS,
in the hope that we can more easily backport it to fix the regression
on PowerPC and ARM systems without breaking the Lantiq system again.
We should follow this up with a more elaborate change to add runtime
detection of endianness, to make sure it also works on all other
combinations of architectures and implementations of the usb-dwc2
device. That patch however will be fairly large and not appropriate
for backports to stable kernels.
Felipe suggested a different approach, using an endianness switching
register to always put the device into LE mode, but unfortunately
the dwc2 hardware does not provide a generic way to do that. Also,
I see no practical way of addressing the problem more generally by
patching architecture specific code on MIPS.

to the start of the ibm_architecture_vec[] array.
However it missed the fact that further down in the array, we hard code
the offset of one of the fields, and then at boot use that value to
patch the value in the array. This means every update to the array must
also update the #define, ugh.
This means that on pseries machines we will misreport to firmware the
number of cores we support, by a factor of threads_per_core.
Fix it for now by updating the #define.

commit b3c0a4dab7e35a9b6d69c0415641d2280fdefb2b upstream.
Because of an improper dereference, a stray 'C' character was output to
the modalias when no 'compatible' was specified. This is the case for
some old PowerMac drivers which only set the 'name' property. Fix it to
let them match again.

4.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alan Stern <stern@rowland.harvard.edu>
commit ab2a4bf83902c170d29ba130a8abb5f9d90559e1 upstream.
The USB core contains a bug that can show up when a USB-3 host
controller is removed. If the primary (USB-2) hcd structure is
released before the shared (USB-3) hcd, the core will try to do a
double-free of the common bandwidth_mutex.
The problem was described in graphical form by Chung-Geol Kim, who
first reported it:

|bandXX_mutex(free*)|<- double free
|__________________|
=================================================
This happens because hcd_release() frees the bandwidth_mutex whenever
it sees a primary hcd being released (which is not a very good idea
in any case), but in the course of releasing the primary hcd, it
changes the pointers in the shared hcd in such a way that the shared
hcd will appear to be primary when it gets released.
This patch fixes the problem by changing hcd_release() so that it
deallocates the bandwidth_mutex only when the _last_ hcd structure
referencing it is released. The patch also removes an unnecessary
test, so that when an hcd is released, both the shared_hcd and
primary_hcd pointers in the hcd's peer will be cleared.

| In reply to | #1450166 |
4.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gavin Shan <gwshan@linux.vnet.ibm.com>
commit 8a934efe94347eee843aeea65bdec8077a79e259 upstream.
In commit 8445a87f7092 "powerpc/iommu: Remove the dependency on EEH
struct in DDW mechanism", the PE address was replaced with the PCI
config address in order to remove dependency on EEH. According to PAPR
spec, firmware (pHyp or QEMU) should accept "xxBBSSxx" format PCI config
address, not "xxxxBBSS" provided by the patch. Note that "BB" is PCI bus
number and "SS" is the combination of slot and function number.
This fixes the PCI address passed to DDW RTAS calls.
