Commit Message: [REGRESSION] Refreshed autofill popup renders garbage
https://bugs.webkit.org/show_bug.cgi?id=83255
http://code.google.com/p/chromium/issues/detail?id=118374
The code used to update only the PopupContainer coordinates as if they were the coordinates relative
to the root view. Instead, a WebWidget positioned relative to the screen origin holds the PopupContainer,
so it is the WebWidget that should be positioned in PopupContainer::refresh(), and the PopupContainer's
location should be (0, 0) (and their sizes should always be equal).
Reviewed by Kent Tamura.
No new tests, as the popup appearance is not testable in WebKit.
* platform/chromium/PopupContainer.cpp:
(WebCore::PopupContainer::layoutAndCalculateWidgetRect): Variable renamed.
(WebCore::PopupContainer::showPopup): Use m_originalFrameRect rather than frameRect()
for passing into chromeClient.
(WebCore::PopupContainer::showInRect): Set up the correct frameRect() for the container.
(WebCore::PopupContainer::refresh): Resize the container and position the WebWidget correctly.

The tty is NULL when the port is hanging up.
chase_port() needs to check for this.
This patch is intended for stable series.
The behavior was observed and tested in Linux 3.2 and 3.7.1.

Commit Message: KVM: x86: work around infinite loop in microcode when #AC is delivered
It was found that a guest can DoS a host by triggering an infinite
stream of "alignment check" (#AC) exceptions. This causes the
microcode to enter an infinite loop where the core never receives
another interrupt. The host kernel panics pretty quickly due to the
effects (CVE-2015-5307).

When early abort is occurred due to invalid ACPI information, Linux kernel
terminates ACPI by calling acpi_terminate() function. The function calls
acpi_ns_terminate() function to delete namespace data and ACPI operand cache
(acpi_gbl_module_code_list).
But the deletion code in acpi_ns_terminate() function is wrapped in
ACPI_EXEC_APP definition, therefore the code is only executed when the
definition exists. If the define doesn't exist, ACPI operand cache
(acpi_gbl_module_code_list) is leaked, and stack dump is shown in kernel log.
This causes a security threat because the old kernel (<= 4.9) shows memory
locations of kernel functions in stack dump, therefore kernel ASLR can be
neutralized.
To fix ACPI operand leak for enhancing security, I made a patch which
removes the ACPI_EXEC_APP define in acpi_ns_terminate() function for
executing the deletion code unconditionally.

Ensure that the BrowserCompositorMac not hold on to a compositor lock
when requested to clear its compositor frame. This lock may be held
indefinitely (if the renderer hangs) and so the frame will never be
cleared.

Commit Message: ofproto: Fix OVS crash when reverting old flows in bundle commit
During bundle commit flows which are added in bundle are applied
to ofproto in-order. In case if a flow cannot be added (e.g. flow
action is go-to group id which does not exist), OVS tries to
revert back all previous flows which were successfully applied
from the same bundle. This is possible since OVS maintains list
of old flows which were replaced by flows from the bundle.
While reinserting old flows ovs asserts due to check on rule
state != RULE_INITIALIZED. This will work only for new flows, but
for old flow the rule state will be RULE_REMOVED. This is causing
an assert and OVS crash.
The ovs assert check should be modified to != RULE_INSERTED to prevent
any existing rule being re-inserted and allow new rules and old rules
(in case of revert) to get inserted.
Here is an example to trigger the assert:
$ ovs-vsctl add-br br-test -- set Bridge br-test datapath_type=netdev
$ cat flows.txt
flow add table=1,priority=0,in_port=2,actions=NORMAL
flow add table=1,priority=0,in_port=3,actions=NORMAL
$ ovs-ofctl dump-flows -OOpenflow13 br-test
cookie=0x0, duration=2.465s, table=1, n_packets=0, n_bytes=0, priority=0,in_port=2 actions=NORMAL
cookie=0x0, duration=2.465s, table=1, n_packets=0, n_bytes=0, priority=0,in_port=3 actions=NORMAL
$ cat flow-modify.txt
flow modify table=1,priority=0,in_port=2,actions=drop
flow modify table=1,priority=0,in_port=3,actions=group:10
$ ovs-ofctl bundle br-test flow-modify.txt -OOpenflow13
First flow rule will be modified since it is a valid rule. However second
rule is invalid since no group with id 10 exists. Bundle commit tries to
revert (insert) the first rule to old flow which results in ovs_assert at
ofproto_rule_insert__() since old rule->state = RULE_REMOVED.

Commit Message: ipc,sem: fine grained locking for semtimedop
Introduce finer grained locking for semtimedop, to handle the common case
of a program wanting to manipulate one semaphore from an array with
multiple semaphores.
If the call is a semop manipulating just one semaphore in an array with
multiple semaphores, only take the lock for that semaphore itself.
If the call needs to manipulate multiple semaphores, or another caller is
in a transaction that manipulates multiple semaphores, the sem_array lock
is taken, as well as all the locks for the individual semaphores.
On a 24 CPU system, performance numbers with the semop-multi
test with N threads and N semaphores, look like this:

Commit Message: rtnl: fix info leak on RTM_GETLINK request for VF devices
Initialize the mac address buffer with 0 as the driver specific function
will probably not fill the whole buffer. In fact, all in-kernel drivers
fill only ETH_ALEN of the MAX_ADDR_LEN bytes, i.e. 6 of the 32 possible
bytes. Therefore we currently leak 26 bytes of stack memory to userland
via the netlink interface.

but don't use a proper RCU API on the free path, therefore a parallel
__d_free() could free it at the same time. We need to mark the stashed
dentry with DCACHE_RCUACCESS so that __d_free() will be called after all
readers leave RCU.

Commit Message: x86,kvm,vmx: Preserve CR4 across VM entry
CR4 isn't constant; at least the TSD and PCE bits can vary.
TBH, treating CR0 and CR3 as constant scares me a bit, too, but it looks
like it's correct.
This adds a branch and a read from cr4 to each vm entry. Because it is
extremely likely that consecutive entries into the same vcpu will have
the same host cr4 value, this fixes up the vmcs instead of restoring cr4
after the fact. A subsequent patch will add a kernel-wide cr4 shadow,
reducing the overhead in the common case to just two memory reads and a
branch.

Commit Message: Implement a bubble that appears at the top of the screen when a tab enters
fullscreen mode via webkitRequestFullScreen(), telling the user how to exit
fullscreen.
This is implemented as an NSView rather than an NSWindow because the floating
chrome that appears in presentation mode should overlap the bubble.
Content-initiated fullscreen mode makes use of 'presentation mode' on the Mac:
the mode in which the UI is hidden, accessible by moving the cursor to the top
of the screen. On Snow Leopard, this mode is synonymous with fullscreen mode.
On Lion, however, fullscreen mode does not imply presentation mode: in
non-presentation fullscreen mode, the chrome is permanently shown. It is
possible to switch between presentation mode and fullscreen mode using the
presentation mode UI control.
When a tab initiates fullscreen mode on Lion, we enter presentation mode if not
in presentation mode already. When the user exits fullscreen mode using Chrome
UI (i.e. keyboard shortcuts, menu items, buttons, switching tabs, etc.) we
return the user to the mode they were in before the tab entered fullscreen.
BUG=14471
TEST=Enter fullscreen mode using webkitRequestFullScreen. You should see a bubble pop down from the top of the screen.
Need to test the Lion logic somehow, with no Lion trybots.

Commit Message: acpi: Disable ACPI table override if securelevel is set
From the kernel documentation (initrd_table_override.txt):
If the ACPI_INITRD_TABLE_OVERRIDE compile option is true, it is possible
to override nearly any ACPI table provided by the BIOS with an
instrumented, modified one.
When securelevel is set, the kernel should disallow any unauthenticated
changes to kernel space. ACPI tables contain code invoked by the kernel, so
do not allow ACPI tables to be overridden if securelevel is set.

Commit Message: [Payment Handler] Don't wait for response from closed payment app.
Before this patch, tapping the back button on top of the payment handler
window on desktop would not affect the |response_helper_|, which would
continue waiting for a response from the payment app. The service worker
of the closed payment app could timeout after 5 minutes and invoke the
|response_helper_|. Depending on what else the user did afterwards, in
the best case scenario, the payment sheet would display a "Transaction
failed" error message. In the worst case scenario, the
|response_helper_| would be used after free.
This patch clears the |response_helper_| in the PaymentRequestState and
in the ServiceWorkerPaymentInstrument after the payment app is closed.
After this patch, the cancelled payment app does not show "Transaction
failed" and does not use memory after it was freed.

Commit Message: net: add validation for the socket syscall protocol argument
郭永刚 reported that one could simply crash the kernel as root by
using a simple program:
int socket_fd;
struct sockaddr_in addr;
addr.sin_port = 0;
addr.sin_addr.s_addr = INADDR_ANY;
addr.sin_family = 10;
socket_fd = socket(10,3,0x40000000);
connect(socket_fd , &addr,16);
AF_INET, AF_INET6 sockets actually only support 8-bit protocol
identifiers. inet_sock's skc_protocol field thus is sized accordingly,
thus larger protocol identifiers simply cut off the higher bits and
store a zero in the protocol fields.
This could lead to e.g. NULL function pointer because as a result of
the cut off inet_num is zero and we call down to inet_autobind, which
is NULL for raw sockets.

Commit Message: Implement a bubble that appears at the top of the screen when a tab enters
fullscreen mode via webkitRequestFullScreen(), telling the user how to exit
fullscreen.
This is implemented as an NSView rather than an NSWindow because the floating
chrome that appears in presentation mode should overlap the bubble.
Content-initiated fullscreen mode makes use of 'presentation mode' on the Mac:
the mode in which the UI is hidden, accessible by moving the cursor to the top
of the screen. On Snow Leopard, this mode is synonymous with fullscreen mode.
On Lion, however, fullscreen mode does not imply presentation mode: in
non-presentation fullscreen mode, the chrome is permanently shown. It is
possible to switch between presentation mode and fullscreen mode using the
presentation mode UI control.
When a tab initiates fullscreen mode on Lion, we enter presentation mode if not
in presentation mode already. When the user exits fullscreen mode using Chrome
UI (i.e. keyboard shortcuts, menu items, buttons, switching tabs, etc.) we
return the user to the mode they were in before the tab entered fullscreen.
BUG=14471
TEST=Enter fullscreen mode using webkitRequestFullScreen. You should see a bubble pop down from the top of the screen.
Need to test the Lion logic somehow, with no Lion trybots.

Commit Message: Unused iocbs in a batch should not be accounted as active.
commit 69e4747ee9727d660b88d7e1efe0f4afcb35db1b upstream.
Since commit 080d676de095 ("aio: allocate kiocbs in batches") iocbs are
allocated in a batch during processing of first iocbs. All iocbs in a
batch are automatically added to ctx->active_reqs list and accounted in
ctx->reqs_active.
If one (not the last one) of iocbs submitted by an user fails, further
iocbs are not processed, but they are still present in ctx->active_reqs
and accounted in ctx->reqs_active. This causes process to stuck in a D
state in wait_for_all_aios() on exit since ctx->reqs_active will never
go down to zero. Furthermore since kiocb_batch_free() frees iocb
without removing it from active_reqs list the list become corrupted
which may cause oops.
Fix this by removing iocb from ctx->active_reqs and updating
ctx->reqs_active in kiocb_batch_free().

Commit Message: libwebm: Pull from upstream
Rolling mkvparser from upstream. Primarily for fixing a bug on parsing
failures with certain Opus WebM files.
Upstream commit hash of this pull: 574045edd4ecbeb802ee3f1d214b5510269852ae
The diff is so huge because there were some style clean ups upstream.
But it was ensured that there were no breaking changes when the style
clean ups was done upstream.

Commit Message: Refactors to simplify rename pathway in DownloadFileManager.
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: Fix order of arguments to compat_put_time[spec|val]
Commit 644595f89620 ("compat: Handle COMPAT_USE_64BIT_TIME in
net/socket.c") introduced a bug where the helper functions to take
either a 64-bit or compat time[spec|val] got the arguments in the wrong
order, passing the kernel stack pointer off as a user pointer (and vice
versa).
Because of the user address range check, that in turn then causes an
EFAULT due to the user pointer range checking failing for the kernel
address. Incorrectly resuling in a failed system call for 32-bit
processes with a 64-bit kernel.
On odder architectures like HP-PA (with separate user/kernel address
spaces), it can be used read kernel memory.

Commit Message: [Payment Handler] Don't wait for response from closed payment app.
Before this patch, tapping the back button on top of the payment handler
window on desktop would not affect the |response_helper_|, which would
continue waiting for a response from the payment app. The service worker
of the closed payment app could timeout after 5 minutes and invoke the
|response_helper_|. Depending on what else the user did afterwards, in
the best case scenario, the payment sheet would display a "Transaction
failed" error message. In the worst case scenario, the
|response_helper_| would be used after free.
This patch clears the |response_helper_| in the PaymentRequestState and
in the ServiceWorkerPaymentInstrument after the payment app is closed.
After this patch, the cancelled payment app does not show "Transaction
failed" and does not use memory after it was freed.

Commit Message: ofp-group: Don't assert-fail decoding bad OF1.5 group mod type or command.
When decoding a group mod, the current code validates the group type and
command after the whole group mod has been decoded. The OF1.5 decoder,
however, tries to use the type and command earlier, when it might still be
invalid. This caused an assertion failure (via OVS_NOT_REACHED). This
commit fixes the problem.
ovs-vswitchd does not enable support for OpenFlow 1.5 by default.

Commit Message: perf/core: Fix concurrent sys_perf_event_open() vs. 'move_group' race
Di Shen reported a race between two concurrent sys_perf_event_open()
calls where both try and move the same pre-existing software group
into a hardware context.
The problem is exactly that described in commit:
f63a8daa5812 ("perf: Fix event->ctx locking")
... where, while we wait for a ctx->mutex acquisition, the event->ctx
relation can have changed under us.
That very same commit failed to recognise sys_perf_event_context() as an
external access vector to the events and thereby didn't apply the
established locking rules correctly.
So while one sys_perf_event_open() call is stuck waiting on
mutex_lock_double(), the other (which owns said locks) moves the group
about. So by the time the former sys_perf_event_open() acquires the
locks, the context we've acquired is stale (and possibly dead).
Apply the established locking rules as per perf_event_ctx_lock_nested()
to the mutex_lock_double() for the 'move_group' case. This obviously means
we need to validate state after we acquire the locks.

Commit Message: Separate repaint and layout requirements of StyleDifference (Step 1)
Previously StyleDifference was an enum that proximately bigger values
imply smaller values (e.g. StyleDifferenceLayout implies
StyleDifferenceRepaint). This causes unnecessary repaints in some cases
on layout change.
Convert StyleDifference to a structure containing relatively independent
flags.
This change doesn't directly improve the result, but can make further
repaint optimizations possible.
Step 1 doesn't change any functionality. RenderStyle still generate the
legacy StyleDifference enum when comparing styles and convert the result
to the new StyleDifference. Implicit requirements are not handled during
the conversion.
Converted call sites to use the new StyleDifference according to the
following conversion rules:
- diff == StyleDifferenceEqual (&& !context) => diff.hasNoChange()
- diff == StyleDifferenceRepaint => diff.needsRepaintObjectOnly()
- diff == StyleDifferenceRepaintLayer => diff.needsRepaintLayer()
- diff == StyleDifferenceRepaint || diff == StyleDifferenceRepaintLayer => diff.needsRepaintLayer()
- diff >= StyleDifferenceRepaint => diff.needsRepaint() || diff.needsLayout()
- diff >= StyleDifferenceRepaintLayer => diff.needsRepaintLayer() || diff.needsLayout()
- diff > StyleDifferenceRepaintLayer => diff.needsLayout()
- diff == StyleDifferencePositionedMovementLayoutOnly => diff.needsPositionedMovementLayoutOnly()
- diff == StyleDifferenceLayout => diff.needsFullLayout()
