* [PATCH bpf 4/9] bpf: fix 32-bit ALU op verification
From: Alexei Starovoitov @ 2017-12-19  4:11 UTC (permalink / raw)
  To: David S . Miller
  Cc: Daniel Borkmann, Jann Horn, Edward Cree, netdev, kernel-team
In-Reply-To: <20171219041201.1979983-1-ast@kernel.org>

From: Jann Horn <jannh@google.com>

32-bit ALU ops operate on 32-bit values and have 32-bit outputs.
Adjust the verifier accordingly.

* [PATCH bpf 6/9] bpf: force strict alignment checks for stack pointers

In-Reply-To: <20171219041201.1979983-1-ast@kernel.org>

From: Jann Horn <jannh@google.com>

Force strict alignment checks for stack pointers because the tracking of
stack spills relies on it; unaligned stack accesses can lead to corruption
of spilled registers, which is exploitable.

Incorrect signed bounds were being computed.
If the old upper signed bound was positive and the old lower signed bound was
negative, this could cause the new upper signed bound to be too low,
leading to security issues.

* [PATCH V2 net-next 16/17] net: hns3: Increase the default depth of bucket for TM shaper

In-Reply-To: <1513656159-127589-1-git-send-email-lipeng321@huawei.com>

Burstiness of a flow is determined by the depth of a bucket, When the
upper rate of shaper is large, the current depth of a bucket is not
enough.

The default upper rate of shaper is 100G, so increase the depth of
a bucket according to UM.

When auto-negotiation is enabled, the MAC flow control settings is
based on the flow control negotiation result. And it should be configured
after a valid link has been established. This patch adds support to update
flow control settings after auto-negotiation has completed.

* [PATCH V2 net-next 11/17] net: hns3: fix for getting auto-negotiation state in hclge_get_autoneg
From: Lipeng @ 2017-12-19  4:02 UTC (permalink / raw)
  To: davem; +Cc: netdev, linux-kernel, linuxarm, salil.mehta, lipeng321
In-Reply-To: <1513656159-127589-1-git-send-email-lipeng321@huawei.com>

From: Fuyun Liang <liangfuyun1@huawei.com>

When phy exists, we use the value of phydev.autoneg to represent the
auto-negotiation state of hardware. Otherwise, we use the value of
mac.autoneg to represent it.

This patch fixes for getting a error value of auto-negotiation state in
hclge_get_autoneg().

* [PATCH V2 net-next 10/17] net: hns3: cleanup mac auto-negotiation state query
From: Lipeng @ 2017-12-19  4:02 UTC (permalink / raw)
  To: davem; +Cc: netdev, linux-kernel, linuxarm, salil.mehta, lipeng321
In-Reply-To: <1513656159-127589-1-git-send-email-lipeng321@huawei.com>

From: Fuyun Liang <liangfuyun1@huawei.com>

When checking whether auto-negotiation is on, driver only needs to
check the value of mac.autoneg(SW) directly, and does not need to
query it from hardware. Because this value is always synchronized
with the auto-negotiation state of hardware.

This patch removes the mac auto-negotiation state query.

Except, the failed init path does not call qdisc_destroy.

stacktrace shouldn't post non kernel values, unless there's a frame
pointer that isn't handled by kallsyms.

As for the other two, we could probably force a failure, like:

 # echo 'hist:keys=hrtimer.sym' > \
     events/timer/hrtimer_start/trigger
 # cat events/timer/hrtimer_start/hist

And then just add sym-offset too.

Can you try the above.

* [PATCH V2 net-next 14/17] net: hns3: add Asym Pause support to phy default features
From: Lipeng @ 2017-12-19  4:02 UTC (permalink / raw)
  To: davem; +Cc: netdev, linux-kernel, linuxarm, salil.mehta, lipeng321
In-Reply-To: <1513656159-127589-1-git-send-email-lipeng321@huawei.com>

From: Fuyun Liang <liangfuyun1@huawei.com>

commit c4fb2cdf575d ("net: hns3: fix a bug for phy supported feature
initialization") adds default supported features for phy, but our hardware
also supports Asym Pause. This patch adds Asym Pause support to phy
default features to prevent Asym Pause can not be advertised when the phy
negotiates flow control.

Fixes: c4fb2cdf575d ("net: hns3: fix a bug for phy supported feature initialization")
