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: caif: Fix missing msg_namelen update in caif_seqpkt_recvmsg()
The current code does not fill the msg_name member in case it is set.
It also does not set the msg_namelen member to 0 and therefore makes
net/socket.c leak the local, uninitialized sockaddr_storage variable
to userland -- 128 bytes of kernel stack memory.
Fix that by simply setting msg_namelen to 0 as obviously nobody cared
about caif_seqpkt_recvmsg() not filling the msg_name in case it was
set.

LocalFrame has |should_send_resource_timing_info_to_parent_| flag not to
send timing info to parent except for the first navigation. This flag is
cleared when the first timing is sent to parent, however this does not happen
if iframe's first navigation was by back-forward navigation. For such
iframes, we shouldn't send timings to parent at all.

Commit Message: af_netlink: force credentials passing [CVE-2012-3520]
Pablo Neira Ayuso discovered that avahi and
potentially NetworkManager accept spoofed Netlink messages because of a
kernel bug. The kernel passes all-zero SCM_CREDENTIALS ancillary data
to the receiver if the sender did not provide such data, instead of not
including any such data at all or including the correct data from the
peer (as it is the case with AF_UNIX).
This bug was introduced in commit 16e572626961
(af_unix: dont send SCM_CREDENTIALS by default)
This patch forces passing credentials for netlink, as
before the regression.
Another fix would be to not add SCM_CREDENTIALS in
netlink messages if not provided by the sender, but it
might break some programs.

Code: bool RenderWidgetHostViewAndroid::HasAcceleratedSurface(
const gfx::Size& desired_size) {
NOTREACHED();
return false;
}
Commit Message: Implement TextureImageTransportSurface using texture mailbox
This has a couple of advantages:
- allow tearing down and recreating the UI parent context without
losing the renderer contexts
- do not require a context to be able to generate textures when
creating the GLSurfaceHandle
- clearer ownership semantics that potentially allows for more
robust and easier lost context handling/thumbnailing/etc., since a texture is at
any given time owned by either: UI parent, mailbox, or
TextureImageTransportSurface
- simplify frontbuffer protection logic;
the frontbuffer textures are now owned by RWHV where they are refcounted
The TextureImageTransportSurface informs RenderWidgetHostView of the
mailbox names for the front- and backbuffer textures by
associating them with a surface_handle (1 or 2) in the AcceleratedSurfaceNew message.
During SwapBuffers() or PostSubBuffer() cycles, it then uses
produceTextureCHROMIUM() and consumeTextureCHROMIUM()
to transfer ownership between renderer and browser compositor.
RWHV sends back the surface_handle of the buffer being returned with the Swap ACK
(or 0 if no buffer is being returned in which case TextureImageTransportSurface will
allocate a new texture - note that this could be used to
simply keep textures for thumbnailing).

Commit Message: unix: correctly track in-flight fds in sending process user_struct
The commit referenced in the Fixes tag incorrectly accounted the number
of in-flight fds over a unix domain socket to the original opener
of the file-descriptor. This allows another process to arbitrary
deplete the original file-openers resource limit for the maximum of
open files. Instead the sending processes and its struct cred should
be credited.
To do so, we add a reference counted struct user_struct pointer to the
scm_fp_list and use it to account for the number of inflight unix fds.

One cgroup maintainer mentioned that "cgroup is trying to offline
a cpuset css, which takes place under cgroup_mutex. The offlining
ends up trying to drain active usages of a sysctl table which apprently
is not happening."
The real reason is that proc_sys_readdir doesn't drop reference added
by grab_header when return from !dir_emit_dots path. So this cpuset
offline path will wait here forever.

Actually such a URB is killed properly at disconnection when the
device gets probed successfully, and what we need is to apply it for
the error-path, too.
In this patch, we apply snd_usb_mixer_disconnect() at releasing.
Also introduce a new flag, disconnected, to struct usb_mixer_interface
for not performing the disconnection procedure twice.

Commit Message: usb: dwc3: gadget: never call ->complete() from ->ep_queue()
This is a requirement which has always existed but, somehow, wasn't
reflected in the documentation and problems weren't found until now
when Tuba Yavuz found a possible deadlock happening between dwc3 and
f_hid. She described the situation as follows:
spin_lock_irqsave(&hidg->write_spinlock, flags); // first acquire
/* we our function has been disabled by host */
if (!hidg->req) {
free_ep_req(hidg->in_ep, hidg->req);
goto try_again;
}
[...]
status = usb_ep_queue(hidg->in_ep, hidg->req, GFP_ATOMIC);
=>
[...]
=> usb_gadget_giveback_request
=>
f_hidg_req_complete
=>
spin_lock_irqsave(&hidg->write_spinlock, flags); // second acquire
Note that this happens because dwc3 would call ->complete() on a
failed usb_ep_queue() due to failed Start Transfer command. This is,
anyway, a theoretical situation because dwc3 currently uses "No
Response Update Transfer" command for Bulk and Interrupt endpoints.
It's still good to make this case impossible to happen even if the "No
Reponse Update Transfer" command is changed.

Commit Message: mime-actions: use file metadata for trusting desktop files
Currently we only trust desktop files that have the executable bit
set, and don't replace the displayed icon or the displayed name until
it's trusted, which prevents for running random programs by a malicious
desktop file.
However, the executable permission is preserved if the desktop file
comes from a compressed file.
To prevent this, add a metadata::trusted metadata to the file once the
user acknowledges the file as trusted. This adds metadata to the file,
which cannot be added unless it has access to the computer.
Also remove the SHEBANG "trusted" content we were putting inside the
desktop file, since that doesn't add more security since it can come
with the file itself.

Commit Message: mm: try_to_unmap_cluster() should lock_page() before mlocking
A BUG_ON(!PageLocked) was triggered in mlock_vma_page() by Sasha Levin
fuzzing with trinity. The call site try_to_unmap_cluster() does not lock
the pages other than its check_page parameter (which is already locked).
The BUG_ON in mlock_vma_page() is not documented and its purpose is
somewhat unclear, but apparently it serializes against page migration,
which could otherwise fail to transfer the PG_mlocked flag. This would
not be fatal, as the page would be eventually encountered again, but
NR_MLOCK accounting would become distorted nevertheless. This patch adds
a comment to the BUG_ON in mlock_vma_page() and munlock_vma_page() to that
effect.
The call site try_to_unmap_cluster() is fixed so that for page !=
check_page, trylock_page() is attempted (to avoid possible deadlocks as we
already have check_page locked) and mlock_vma_page() is performed only
upon success. If the page lock cannot be obtained, the page is left
without PG_mlocked, which is again not a problem in the whole unevictable
memory design.

Previously, the `psf->header` buffer was a fixed length specified by
`SF_HEADER_LEN` which was set to `12292`. This was problematic for
two reasons; this value was un-necessarily large for the majority
of files and too small for some others.
Now the size of the header buffer starts at 256 bytes and grows as
necessary up to a maximum of 100k.

Commit Message: Fix a buffer overflow / heap corruption issue that could occur if a
malformed JSON string was passed on the control channel. This issue,
present in the cJSON library, was already fixed upstream, so was
addressed here in iperf3 by importing a newer version of cJSON (plus
local ESnet modifications).
Discovered and reported by Dave McDaniel, Cisco Talos.
Based on a patch by @dopheide-esnet, with input from @DaveGamble.

Commit Message: KEYS: Remove key_type::match in favour of overriding default by match_preparse
A previous patch added a ->match_preparse() method to the key type. This is
allowed to override the function called by the iteration algorithm.
Therefore, we can just set a default that simply checks for an exact match of
the key description with the original criterion data and allow match_preparse
to override it as needed.
The key_type::match op is then redundant and can be removed, as can the
user_match() function.

Commit Message: ppp: take reference on channels netns
Let channels hold a reference on their network namespace.
Some channel types, like ppp_async and ppp_synctty, can have their
userspace controller running in a different namespace. Therefore they
can't rely on them to preclude their netns from being removed from
under them.

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: Fix several ineffective integer overflow checks
Commit edd4a76 (which addressed bugs 15328708, 15342615, 15342751) added
several integer overflow checks. Unfortunately, those checks fail to take into
account integer promotion rules and are thus themselves subject to an integer
overflow. Cast the sizeof() operator to a uint64_t to force promotion while
multiplying.

Commit Message: Fix SPNEGO context aliasing bugs [CVE-2015-2695]
The SPNEGO mechanism currently replaces its context handle with the
mechanism context handle upon establishment, under the assumption that
most GSS functions are only called after context establishment. This
assumption is incorrect, and can lead to aliasing violations for some
programs. Maintain the SPNEGO context structure after context
establishment and refer to it in all GSS methods. Add initiate and
opened flags to the SPNEGO context structure for use in
gss_inquire_context() prior to context establishment.
CVE-2015-2695:
In MIT krb5 1.5 and later, applications which call
gss_inquire_context() on a partially-established SPNEGO context can
cause the GSS-API library to read from a pointer using the wrong type,
generally causing a process crash. This bug may go unnoticed, because
the most common SPNEGO authentication scenario establishes the context
after just one call to gss_accept_sec_context(). Java server
applications using the native JGSS provider are vulnerable to this
bug. A carefully crafted SPNEGO packet might allow the
gss_inquire_context() call to succeed with attacker-determined
results, but applications should not make access control decisions
based on gss_inquire_context() results prior to context establishment.

Commit Message: scsi: libsas: direct call probe and destruct
In commit 87c8331fcf72 ("[SCSI] libsas: prevent domain rediscovery
competing with ata error handling") introduced disco mutex to prevent
rediscovery competing with ata error handling and put the whole
revalidation in the mutex. But the rphy add/remove needs to wait for the
error handling which also grabs the disco mutex. This may leads to dead
lock.So the probe and destruct event were introduce to do the rphy
add/remove asynchronously and out of the lock.
The asynchronously processed workers makes the whole discovery process
not atomic, the other events may interrupt the process. For example,
if a loss of signal event inserted before the probe event, the
sas_deform_port() is called and the port will be deleted.
And sas_port_delete() may run before the destruct event, but the
port-x:x is the top parent of end device or expander. This leads to
a kernel WARNING such as:

Make probe and destruct a direct call in the disco and revalidate function,
but put them outside the lock. The whole discovery or revalidate won't
be interrupted by other events. And the DISCE_PROBE and DISCE_DESTRUCT
event are deleted as a result of the direct call.
Introduce a new list to destruct the sas_port and put the port delete after
the destruct. This makes sure the right order of destroying the sysfs
kobject and fix the warning above.
In sas_ex_revalidate_domain() have a loop to find all broadcasted
device, and sometimes we have a chance to find the same expander twice.
Because the sas_port will be deleted at the end of the whole revalidate
process, sas_port with the same name cannot be added before this.
Otherwise the sysfs will complain of creating duplicate filename. Since
the LLDD will send broadcast for every device change, we can only
process one expander's revalidation.

const ui::Range& range,
const std::vector<gfx::Rect>& character_bounds) {
if (view_)
view_->ImeCompositionRangeChanged(range, character_bounds);
}
Commit Message: Implement TextureImageTransportSurface using texture mailbox
This has a couple of advantages:
- allow tearing down and recreating the UI parent context without
losing the renderer contexts
- do not require a context to be able to generate textures when
creating the GLSurfaceHandle
- clearer ownership semantics that potentially allows for more
robust and easier lost context handling/thumbnailing/etc., since a texture is at
any given time owned by either: UI parent, mailbox, or
TextureImageTransportSurface
- simplify frontbuffer protection logic;
the frontbuffer textures are now owned by RWHV where they are refcounted
The TextureImageTransportSurface informs RenderWidgetHostView of the
mailbox names for the front- and backbuffer textures by
associating them with a surface_handle (1 or 2) in the AcceleratedSurfaceNew message.
During SwapBuffers() or PostSubBuffer() cycles, it then uses
produceTextureCHROMIUM() and consumeTextureCHROMIUM()
to transfer ownership between renderer and browser compositor.
RWHV sends back the surface_handle of the buffer being returned with the Swap ACK
(or 0 if no buffer is being returned in which case TextureImageTransportSurface will
allocate a new texture - note that this could be used to
simply keep textures for thumbnailing).

Commit Message: ipsec: Fix aborted xfrm policy dump crash
An independent security researcher, Mohamed Ghannam, has reported
this vulnerability to Beyond Security's SecuriTeam Secure Disclosure
program.
The xfrm_dump_policy_done function expects xfrm_dump_policy to
have been called at least once or it will crash. This can be
triggered if a dump fails because the target socket's receive
buffer is full.
This patch fixes it by using the cb->start mechanism to ensure that
the initialisation is always done regardless of the buffer situation.

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: Security: Cross Protocol Scripting protection.
This is an attempt at mitigating problems due to cross protocol
scripting, an attack targeting services using line oriented protocols
like Redis that can accept HTTP requests as valid protocol, by
discarding the invalid parts and accepting the payloads sent, for
example, via a POST request.
For this to be effective, when we detect POST and Host: and terminate
the connection asynchronously, the networking code was modified in order
to never process further input. It was later verified that in a
pipelined request containing a POST command, the successive commands are
not executed.

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()

Commit Message: crypto: mcryptd - Check mcryptd algorithm compatibility
Algorithms not compatible with mcryptd could be spawned by mcryptd
with a direct crypto_alloc_tfm invocation using a "mcryptd(alg)" name
construct. This causes mcryptd to crash the kernel if an arbitrary
"alg" is incompatible and not intended to be used with mcryptd. It is
an issue if AF_ALG tries to spawn mcryptd(alg) to expose it externally.
But such algorithms must be used internally and not be exposed.
We added a check to enforce that only internal algorithms are allowed
with mcryptd at the time mcryptd is spawning an algorithm.

Commit Message: Reimplement httpd's support for byte ranges.
The previous implementation loaded all the output into a single output
buffer and used its size to determine the Content-Length of the body.
The new implementation calculates the body length first and writes the
individual ranges in an async way using the bufferevent mechanism.
This prevents httpd from using too much memory and applies the
watermark and throttling mechanisms to range requests.

Original change's description:
> PageInfo: decouple safe browsing and TLS statii.
>
> Previously, the Page Info bubble maintained a single variable to
> identify all reasons that a page might have a non-standard status. This
> lead to the display logic making assumptions about, for instance, the
> validity of a certificate when the page was flagged by Safe Browsing.
>
> This CL separates out the Safe Browsing status from the site identity
> status so that the page info bubble can inform the user that the site's
> certificate is invalid, even if it's also flagged by Safe Browsing.

re-introduced https://crbug.com/666714 locally (the bug the test was
added for), and reran the test to confirm that it still covers the bug.

Commit Message: ppp: take reference on channels netns
Let channels hold a reference on their network namespace.
Some channel types, like ppp_async and ppp_synctty, can have their
userspace controller running in a different namespace. Therefore they
can't rely on them to preclude their netns from being removed from
under them.

Commit Message: dccp: fix info leak via getsockopt(DCCP_SOCKOPT_CCID_TX_INFO)
The CCID3 code fails to initialize the trailing padding bytes of struct
tfrc_tx_info added for alignment on 64 bit architectures. It that for
potentially leaks four bytes kernel stack via the getsockopt() syscall.
Add an explicit memset(0) before filling the structure to avoid the
info leak.

Commit Message: veth: Dont kfree_skb() after dev_forward_skb()
In case of congestion, netif_rx() frees the skb, so we must assume
dev_forward_skb() also consume skb.
Bug introduced by commit 445409602c092
(veth: move loopback logic to common location)
We must change dev_forward_skb() to always consume skb, and veth to not
double free it.

Code: void WebContentsImpl::ReplaceMisspelling(const base::string16& word) {

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.
