Commit Message: crypto/evp: harden AEAD ciphers.
Originally a crash in 32-bit build was reported CHACHA20-POLY1305
cipher. The crash is triggered by truncated packet and is result
of excessive hashing to the edge of accessible memory. Since hash
operation is read-only it is not considered to be exploitable
beyond a DoS condition. Other ciphers were hardened.

Commit Message: KVM: X86: Don't report L2 emulation failures to user-space
This patch prevents that emulation failures which result
from emulating an instruction for an L2-Guest results in
being reported to userspace.
Without this patch a malicious L2-Guest would be able to
kill the L1 by triggering a race-condition between an vmexit
and the instruction emulator.
With this patch the L2 will most likely only kill itself in
this situation.

Commit Message: [media] dvb-usb-v2: avoid use-after-free
I ran into a stack frame size warning because of the on-stack copy of
the USB device structure:
drivers/media/usb/dvb-usb-v2/dvb_usb_core.c: In function 'dvb_usbv2_disconnect':
drivers/media/usb/dvb-usb-v2/dvb_usb_core.c:1029:1: error: the frame size of 1104 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
Copying a device structure like this is wrong for a number of other reasons
too aside from the possible stack overflow. One of them is that the
dev_info() call will print the name of the device later, but AFAICT
we have only copied a pointer to the name earlier and the actual name
has been freed by the time it gets printed.
This removes the on-stack copy of the device and instead copies the
device name using kstrdup(). I'm ignoring the possible failure here
as both printk() and kfree() are able to deal with NULL pointers.

Commit Message: SELinux: Fix kernel BUG on empty security contexts.
Setting an empty security context (length=0) on a file will
lead to incorrectly dereferencing the type and other fields
of the security context structure, yielding a kernel BUG.
As a zero-length security context is never valid, just reject
all such security contexts whether coming from userspace
via setxattr or coming from the filesystem upon a getxattr
request by SELinux.
Setting a security context value (empty or otherwise) unknown to
SELinux in the first place is only possible for a root process
(CAP_MAC_ADMIN), and, if running SELinux in enforcing mode, only
if the corresponding SELinux mac_admin permission is also granted
to the domain by policy. In Fedora policies, this is only allowed for
specific domains such as livecd for setting down security contexts
that are not defined in the build host policy.
Reproducer:
su
setenforce 0
touch foo
setfattr -n security.selinux foo
Caveat:
Relabeling or removing foo after doing the above may not be possible
without booting with SELinux disabled. Any subsequent access to foo
after doing the above will also trigger the BUG.

Commit Message: [Blink>Media] Allow autoplay muted on Android by default
There was a mistake causing autoplay muted is shipped on Android
but it will be disabled if the chromium embedder doesn't specify
content setting for "AllowAutoplay" preference. This CL makes the
AllowAutoplay preference true by default so that it is allowed by
embedders (including AndroidWebView) unless they explicitly
disable it.

Commit Message: Consider the exit family when applying guard restrictions.
When the new path selection logic went into place, I accidentally
dropped the code that considered the _family_ of the exit node when
deciding if the guard was usable, and we didn't catch that during
code review.
This patch makes the guard_restriction_t code consider the exit
family as well, and adds some (hopefully redundant) checks for the
case where we lack a node_t for a guard but we have a bridge_info_t
for it.

Commit Message: ptrace: ensure arch_ptrace/ptrace_request can never race with SIGKILL
putreg() assumes that the tracee is not running and pt_regs_access() can
safely play with its stack. However a killed tracee can return from
ptrace_stop() to the low-level asm code and do RESTORE_REST, this means
that debugger can actually read/modify the kernel stack until the tracee
does SAVE_REST again.
set_task_blockstep() can race with SIGKILL too and in some sense this
race is even worse, the very fact the tracee can be woken up breaks the
logic.
As Linus suggested we can clear TASK_WAKEKILL around the arch_ptrace()
call, this ensures that nobody can ever wakeup the tracee while the
debugger looks at it. Not only this fixes the mentioned problems, we
can do some cleanups/simplifications in arch_ptrace() paths.
Probably ptrace_unfreeze_traced() needs more callers, for example it
makes sense to make the tracee killable for oom-killer before
access_process_vm().
While at it, add the comment into may_ptrace_stop() to explain why
ptrace_stop() still can't rely on SIGKILL and signal_pending_state().

Commit Message: KVM: unmap pages from the iommu when slots are removed
commit 32f6daad4651a748a58a3ab6da0611862175722f upstream.
We've been adding new mappings, but not destroying old mappings.
This can lead to a page leak as pages are pinned using
get_user_pages, but only unpinned with put_page if they still
exist in the memslots list on vm shutdown. A memslot that is
destroyed while an iommu domain is enabled for the guest will
therefore result in an elevated page reference count that is
never cleared.
Additionally, without this fix, the iommu is only programmed
with the first translation for a gpa. This can result in
peer-to-peer errors if a mapping is destroyed and replaced by a
new mapping at the same gpa as the iommu will still be pointing
to the original, pinned memory address.

Commit Message: MacViews: Enable secure text input for password Textfields.
In Cocoa the NSTextInputContext automatically enables secure text input
when activated and it's in the secure text entry mode.
RenderWidgetHostViewMac did the similar thing for ages following the
WebKit example.
views::Textfield needs to do the same thing in a fashion that's
sycnrhonized with RenderWidgetHostViewMac, otherwise the race conditions
are possible when the Textfield gets focus, activates the secure text
input mode and the RWHVM loses focus immediately afterwards and disables
the secure text input instead of leaving it in the enabled state.

Commit Message: usb: gadget: f_fs: Fix use-after-free
When using asynchronous read or write operations on the USB endpoints the
issuer of the IO request is notified by calling the ki_complete() callback
of the submitted kiocb when the URB has been completed.
Calling this ki_complete() callback will free kiocb. Make sure that the
structure is no longer accessed beyond that point, otherwise undefined
behaviour might occur.

Commit Message: regset: Prevent null pointer reference on readonly regsets
The regset common infrastructure assumed that regsets would always
have .get and .set methods, but not necessarily .active methods.
Unfortunately people have since written regsets without .set methods.
Rather than putting in stub functions everywhere, handle regsets with
null .get or .set methods explicitly.

This is https://chromiumcodereview.appspot.com/10668004 / r144817 (reverted
due to CrOS failure) with the completion logic moved to after the
auto-opening. The tests that test the auto-opening (for web store install)
were waiting for download completion to check install, and hence were
failing when completion was moved earlier.
Doing this right would probably require another state (OPENED).

Commit Message: vfs: Carefully propogate mounts across user namespaces
As a matter of policy MNT_READONLY should not be changable if the
original mounter had more privileges than creator of the mount
namespace.
Add the flag CL_UNPRIVILEGED to note when we are copying a mount from
a mount namespace that requires more privileges to a mount namespace
that requires fewer privileges.
When the CL_UNPRIVILEGED flag is set cause clone_mnt to set MNT_NO_REMOUNT
if any of the mnt flags that should never be changed are set.
This protects both mount propagation and the initial creation of a less
privileged mount namespace.

tcp_read_sock() can have a eat skbs without immediately advancing copied_seq.
This can cause a panic in tcp_collapse() if it is called as a result
of the recv_actor dropping the socket lock.
A userspace program that splices data from a socket to either another
socket or to a file can trigger this bug.

with a malformed ACL:
Program received signal SIGSEGV, Segmentation fault.
archive_acl_from_text_l (acl=<optimised out>, text=0x7e2e92 "", want_type=<optimised out>, sc=<optimised out>) at libarchive/archive_acl.c:1726
1726 switch (*s) {
(gdb) p n
$1 = 1
(gdb) p field[n]
$2 = {start = 0x0, end = 0x0}
Stop this by checking that the length is not zero before beginning
the switch statement.
I am pretty sure this is the bug mentioned in the qsym paper [1],
and I was able to replicate it with a qsym + AFL + afl-rb setup.

Commit Message: Don't dispatch events when XHR is set to sync mode
Any of readystatechange, progress, abort, error, timeout and loadend
event are not specified to be dispatched in sync mode in the latest
spec. Just an exception corresponding to the failure is thrown.
Clean up for readability done in this CL
- factor out dispatchEventAndLoadEnd calling code
- make didTimeout() private
- give error handling methods more descriptive names
- set m_exceptionCode in failure type specific methods
-- Note that for didFailRedirectCheck, m_exceptionCode was not set
in networkError(), but was set at the end of createRequest()
This CL is prep for fixing crbug.com/292422

Commit Message: android: Fix sensors in device service.
This patch fixes a bug that prevented more than one sensor data
to be available at once when using the device motion/orientation
API.
The issue was introduced by this other patch [1] which fixed
some security-related issues in the way shared memory region
handles are managed throughout Chromium (more details at
https://crbug.com/789959).
The device service´s sensor implementation doesn´t work
correctly because it assumes it is possible to create a
writable mapping of a given shared memory region at any
time. This assumption is not correct on Android, once an
Ashmem region has been turned read-only, such mappings
are no longer possible.
To fix the implementation, this CL changes the following:
- PlatformSensor used to require moving a
mojo::ScopedSharedBufferMapping into the newly-created
instance. Said mapping being owned by and destroyed
with the PlatformSensor instance.
With this patch, the constructor instead takes a single
pointer to the corresponding SensorReadingSharedBuffer,
i.e. the area in memory where the sensor-specific
reading data is located, and can be either updated
or read-from.
Note that the PlatformSensor does not own the mapping
anymore.
- PlatformSensorProviderBase holds the *single* writable
mapping that is used to store all SensorReadingSharedBuffer
buffers. It is created just after the region itself,
and thus can be used even after the region's access
mode has been changed to read-only.
Addresses within the mapping will be passed to
PlatformSensor constructors, computed from the
mapping's base address plus a sensor-specific
offset.
The mapping is now owned by the
PlatformSensorProviderBase instance.
Note that, security-wise, nothing changes, because all
mojo::ScopedSharedBufferMapping before the patch actually
pointed to the same writable-page in memory anyway.
Since unit or integration tests didn't catch the regression
when [1] was submitted, this patch was tested manually by
running a newly-built Chrome apk in the Android emulator
and on a real device running Android O.

Commit Message: perf: Remove the nmi parameter from the swevent and overflow interface
The nmi parameter indicated if we could do wakeups from the current
context, if not, we would set some state and self-IPI and let the
resulting interrupt do the wakeup.
For the various event classes:
- hardware: nmi=0; PMI is in fact an NMI or we run irq_work_run from
the PMI-tail (ARM etc.)
- tracepoint: nmi=0; since tracepoint could be from NMI context.
- software: nmi=[0,1]; some, like the schedule thing cannot
perform wakeups, and hence need 0.
As one can see, there is very little nmi=1 usage, and the down-side of
not using it is that on some platforms some software events can have a
jiffy delay in wakeup (when arch_irq_work_raise isn't implemented).
The up-side however is that we can remove the nmi parameter and save a
bunch of conditionals in fast paths.

Commit Message: net: don't allow CAP_NET_ADMIN to load non-netdev kernel modules
Since a8f80e8ff94ecba629542d9b4b5f5a8ee3eb565c any process with
CAP_NET_ADMIN may load any module from /lib/modules/. This doesn't mean
that CAP_NET_ADMIN is a superset of CAP_SYS_MODULE as modules are
limited to /lib/modules/**. However, CAP_NET_ADMIN capability shouldn't
allow anybody load any module not related to networking.
This patch restricts an ability of autoloading modules to netdev modules
with explicit aliases. This fixes CVE-2011-1019.
Arnd Bergmann suggested to leave untouched the old pre-v2.6.32 behavior
of loading netdev modules by name (without any prefix) for processes
with CAP_SYS_MODULE to maintain the compatibility with network scripts
that use autoloading netdev modules by aliases like "eth0", "wlan0".
Currently there are only three users of the feature in the upstream
kernel: ipip, ip_gre and sit.

Commit Message: Prevent renderer initiated back navigation to cancel a browser one.
Renderer initiated back/forward navigations must not be able to cancel ongoing
browser initiated navigation if they are not user initiated.
Note: 'normal' renderer initiated navigation uses the
FrameHost::BeginNavigation() path. A code similar to this patch is done
in NavigatorImpl::OnBeginNavigation().
Test:
-----
Added: NavigationBrowserTest.

Commit Message: Consider the exit family when applying guard restrictions.
When the new path selection logic went into place, I accidentally
dropped the code that considered the _family_ of the exit node when
deciding if the guard was usable, and we didn't catch that during
code review.
This patch makes the guard_restriction_t code consider the exit
family as well, and adds some (hopefully redundant) checks for the
case where we lack a node_t for a guard but we have a bridge_info_t
for it.

Commit Message: Predict integer overflow to avoid buffer overruns.
Several functions, mostly type input functions, calculated an allocation
size such that the calculation wrapped to a small positive value when
arguments implied a sufficiently-large requirement. Writes past the end
of the inadvertent small allocation followed shortly thereafter.
Coverity identified the path_in() vulnerability; code inspection led to
the rest. In passing, add check_stack_depth() to prevent stack overflow
in related functions.
Back-patch to 8.4 (all supported versions). The non-comment hstore
changes touch code that did not exist in 8.4, so that part stops at 9.0.

Commit Message: block: blk_init_allocated_queue() set q->fq as NULL in the fail case
We find the memory use-after-free issue in __blk_drain_queue()
on the kernel 4.14. After read the latest kernel 4.18-rc6 we
think it has the same problem.
Memory is allocated for q->fq in the blk_init_allocated_queue().
If the elevator init function called with error return, it will
run into the fail case to free the q->fq.
Then the __blk_drain_queue() uses the same memory after the free
of the q->fq, it will lead to the unpredictable event.
The patch is to set q->fq as NULL in the fail case of
blk_init_allocated_queue().

This reverts commit 2d475d0ed37bf8f19385537ad31e361f1b21624b. The
permission broker now supports opening devices that are partially
claimed through the OpenPath method and RequestPathAccess will always
fail for these devices so the fallback path from RequestPathAccess to
OpenPath is always taken.
