In commit 96e0bf4b5193d (tcp: Discard segments that ack data not yet
sent) John Dykstra enforced a check against ack sequences.
In commit 354e4aa391ed5 (tcp: RFC 5961 5.2 Blind Data Injection Attack
Mitigation) I added more safety tests.
But we missed fact that these tests are not performed if ACK bit is
not set.
RFC 793 3.9 mandates TCP should drop a frame without ACK flag set.
" fifth check the ACK field,
if the ACK bit is off drop the segment and return"
Not doing so permits an attacker to only guess an acceptable sequence
number, evading stronger checks.
Many thanks to Zhiyun Qian for bringing this issue to our attention.

Unfortunately with !CONFIG_PAGEFLAGS_EXTENDED, (!PageHead) is false, and
(PageHead) is true, for tail pages. If this is indeed the intended
behavior, which I doubt because it breaks cache cleaning on some ARM
systems, then the nomenclature is highly problematic.
This patch makes sure PageHead is only true for head pages and PageTail
is only true for tail pages, and neither is true for non-compound pages.
[ This buglet seems ancient - seems to have been introduced back in Apr
2008 in commit 6a1e7f777f61: "pageflags: convert to the use of new
macros". And the reason nobody noticed is because the PageHead()
tests are almost all about just sanity-checking, and only used on
pages that are actual page heads. The fact that the old code returned
true for tail pages too was thus not really noticeable. - Linus ]

The cpts driver tries to obtain the input clock frequency by calling the
clock's internal 'recalc' method. Since <plat/clock.h> has been removed,
this code can no longer compile.
However, the driver never makes use of the frequency value, so this patch
fixes the issue by removing the offending code altogether.

batadv_iv_ogm_emit_send_time() attempts to calculates a random integer
in the range of 'orig_interval +- BATADV_JITTER' by the below lines.
msecs = atomic_read(&bat_priv->orig_interval) - BATADV_JITTER;
msecs += (random32() % 2 * BATADV_JITTER);
But it actually gets 'orig_interval' or 'orig_interval - BATADV_JITTER'
because '%' and '*' have same precedence and associativity is
left-to-right.
This adds the parentheses at the appropriate position so that it matches
original intension.

Ulrich reported that his USB3 cardreader does not work reliably when
connected to the USB3 port. It turns out that USB3 controller failed to
awaken when plugging in the USB3 cardreader. Further experiments found
that the USB3 host controller can only be awakened via polling, not via PME
interrupt. But if the PCIe port to which the USB3 host controller is
connected is suspended, we cannot poll the controller because its config
space is not accessible when the PCIe port is in a low power state.
To solve the issue, the PCIe port will not be suspended if any subordinate
device needs PME polling.

Add standard #defines for the Supported Link Speeds field in the PCIe
Link Capabilities register.
Note that prior to PCIe spec r3.0, these encodings were defined:
0001b 2.5GT/s Link speed supported
0010b 5.0GT/s and 2.5GT/s Link speed supported
Starting with spec r3.0, these encodings refer to bits 0 and 1 in the
Supported Link Speeds Vector in the Link Capabilities 2 register, and bits
0 and 1 there mean 2.5 GT/s and 5.0 GT/s, respectively. Therefore, code
that followed r2.0 and interpreted 0x1 as 2.5GT/s and 0x2 as 5.0GT/s will
continue to work, and we can identify a device using the new encodings
because it will have a non-zero Link Capabilities 2 register.

Commit 284f5f9 was intended to disable the "only_one_child()" optimization
on Stratus ftServer systems, but its DMI check is wrong. It looks for
DMI_SYS_VENDOR that contains "ftServer", when it should look for
DMI_SYS_VENDOR containing "Stratus" and DMI_PRODUCT_NAME containing
"ftServer".
Tested on Stratus ftServer 6400.

If we request "num_vfs" and the driver's sriov_configure() method enables
exactly that number ("num_vfs_enabled"), we complain "Invalid value for

With user namespaces enabled building f2fs fails with:

e_id is a backwards compatibility field only used for file systems
that haven't been converted to use kuids and kgids. When the posix
acl tag field is neither ACL_USER nor ACL_GROUP assigning e_id is
unnecessary. Remove the assignment so f2fs will build with user

put_pid is called with another spinlock held and irqs disabled.
For now take the easy path and use spin_lock_irqsave(proc_inum_lock)
in proc_free_inum and spin_loc_irq in proc_alloc_inum(proc_inum_lock).

Oleg pointed out that in a pid namespace the sequence.
- pid 1 becomes a zombie
- setns(thepidns), fork,...
- reaping pid 1.
- The injected processes exiting.
Can lead to processes attempting access their child reaper and
instead following a stale pointer.
That waitpid for init can return before all of the processes in
the pid namespace have exited is also unfortunate.
Avoid these problems by disabling the allocation of new pids in a pid
namespace when init dies, instead of when the last process in a pid
namespace is reaped.

When a journal-less ext4 filesystem is mounted on a read-only block
device (blockdev --setro will do), each remount (for other, unrelated,
flags, like suid=>nosuid etc) results in a series of scary messages
from kernel telling about I/O errors on the device.
This is becauese of the following code ext4_remount():
if (sbi->s_journal == NULL)
ext4_commit_super(sb, 1);
at the end of remount procedure, which forces writing (flushing) of
a superblock regardless whenever it is dirty or not, if the filesystem
is readonly or not, and whenever the device itself is readonly or not.
We only need call ext4_commit_super when the file system had been
previously mounted read/write.

Although I put this in, I now think it was a bad decision. For most
users, there is very little to be done in this case. They get the
message, once per day, with no real context or proposed action. TBH,
it generates support calls when it probably does not need to; the
message sounds more dire than the situation really is.
Just nuke it. Normal investigation via blktrace or whatnot can
reveal poor IO patterns if bad performance is encountered.

We cannot wait for transaction commit in journal_unmap_buffer()
because we hold page lock which ranks below transaction start. We
solve the issue by bailing out of journal_unmap_buffer() and
jbd2_journal_invalidatepage() with -EBUSY. Caller is then responsible
for waiting for transaction commit to finish and try invalidation
again. Since the issue can happen only for page stradding i_size, it
is simple enough to manually call jbd2_journal_invalidatepage() for
such page from ext4_setattr(), check the return value and wait if
necessary.

The sequence:
unshare(CLONE_NEWPID)
clone(CLONE_THREAD|CLONE_SIGHAND|CLONE_VM)
Creates a new process in the new pid namespace without setting
pid_ns->child_reaper. After forking this results in a NULL
pointer dereference.
Avoid this and other nonsense scenarios that can show up after
creating a new pid namespace with unshare by adding a new
check in copy_prodcess.

controls API failures"
Commit f0ed2ce840b3 ("[media] uvcvideo: Set error_idx properly for
extended controls API failures") causes user space to behave incorrectly
on one of my test machines (there is no sound under KDE 4.9.4 using
pulseaudio and there is a knotify4 process occupying one of the CPU
cores 100% of the time). Reverting that commit entirely fixes the
problem for me.
However, commit f0ed2ce840b3 appears to do more than it follows from its
changelog, because the changelog only says about the changes related to
ctrls->error_idx, while the commit additionally changes error codes
returned by various functions in uvc_ctrl.c and uvc_v4l2.c. It turns
out that the changes of the returned error codes confuse the user spce,
so it is sufficient to revert the part of commit f0ed2ce840b3 not
mentioned in its changelog to fix the problem.

If an LM73 device does not exist on an I2C bus, attempts to communicate
with the device result in an error code returned from the i2c read/write
functions. The current lm73 driver casts that return value from a s32
type to a s16 type, then converts it to a temperature in celsius.
Because negative temperatures are valid, it is difficult to distinguish
between an error code printed to the response buffer and a negative
temperature recorded by the sensor.
The solution is to evaluate the return value from the i2c functions
before performing any temperature calculations. If the i2c function did
not succeed, the error code should be passed back through the virtual
file system layer instead of being printed into the response buffer.

Pull dm update from Alasdair G Kergon:
"Miscellaneous device-mapper fixes, cleanups and performance
improvements.
Of particular note:
- Disable broken WRITE SAME support in all targets except linear and
striped. Use it when kcopyd is zeroing blocks.
- Remove several mempools from targets by moving the data into the
bio's new front_pad area(which dm calls 'per_bio_data').
- Fix a race in thin provisioning if discards are misused.
- Prevent userspace from interfering with the ioctl parameters and
use kmalloc for the data buffer if it's small instead of vmalloc.
- Throttle some annoying error messages when I/O fails."

This reverts commit 79f77bf9a4e3dd5ead006b8f17e7c4ff07d8374e.
This is obviously wrong, and I have no idea how I missed seeing the
warning in testing: I must just not have looked at the right logs. The
caller bumps rq_resused/rq_next_page, so it will always be hit on a
large enough read.

Commit db5b0ae00712 ("Merge tag 'dt' of git://git.kernel.org/.../arm-soc")
causes a duplicated build target. This patch fixes it and sorts out the
build target alphabetically so that we can recognize something wrong
easily.

When netdev_set_master faild in br_add_if, we should
call br_netpoll_disable to do some cleanup jobs,such
as free the memory of struct netpoll which allocated
in br_netpoll_enable.
