H8300: remove unused barrier defines

From c907e749917f430e3dc62048985c8419778572f9 Mon Sep 17 00:00:00 2001
From: Rolf Eike Beer <eb@emlix.com>
Date: Fri, 14 Jul 2017 11:19:08 +0200
Subject: [PATCH] H8300: remove unused barrier defines

They were introduced in d2a5f4999f6c211adf30d9788349e13988d6f2a7 long after
2e39465abc4b7856a0ea6fcf4f6b4668bb5db877 removed the remnants of all previous
instances from the tree.

sh: configs: Remove useless UEVENT_HELPER_PATH

Remove the CONFIG_UEVENT_HELPER_PATH because:
1. It is disabled since commit 1be01d4a5714 ("driver: base: Disable
CONFIG_UEVENT_HELPER by default") as its dependency (UEVENT_HELPER) was
made default to 'n',
2. It is not recommended (help message: "This should not be used today
[...] creates a high system load") and was kept only for ancient
userland,
3. Certain userland specifically requests it to be disabled (systemd
README: "Legacy hotplug slows down the system and confuses udev").

This reverts a minor fix which could cause us to treat conflicting NLM
locks as nonconflicting.

We have proper fix queued up for 5.3. In the meantime, a quick revert
seems best for 5.2 and stable.

Power management fixes for 5.2-rc3

- Modify the PCI bus type's PM code to avoid putting devices left
by their drivers in D0 on purpose during suspend to idle into
low-power states as doing that may confuse the system resume
callbacks of the drivers in question (Rafael Wysocki).

- Avoid checking ACPI wakeup configuration during system-wide
suspend for suspended devices that do not use ACPI-based wakeup
to allow them to stay in suspend more often (Rafael Wysocki).

- The last phase of hibernation is analogous to system-wide suspend
also because on platforms with ACPI it passes control to the
platform firmware to complete the transision, so make it indicate
that by calling pm_set_suspend_via_firmware() to allow the drivers
that care about this to do the right thing (Rafael Wysocki).

SPDX update for 5.2-rc3, round 1

Here is another set of reviewed patches that adds SPDX tags to different
kernel files, based on a set of rules that are being used to parse the
comments to try to determine that the license of the file is
"GPL-2.0-or-later" or "GPL-2.0-only". Only the "obvious" versions of
these matches are included here, a number of "non-obvious" variants of
text have been found but those have been postponed for later review and
analysis.

There is also a patch in here to add the proper SPDX header to a bunch
of Kbuild files that we have missed in the past due to new files being
added and forgetting that Kbuild uses two different file names for
Makefiles. This issue was reported by the Kbuild maintainer.

These patches have been out for review on the linux-spdx@vger mailing
list, and while they were created by automatic tools, they were
hand-verified by a bunch of different people, all whom names are on the
patches are reviewers.

USB fixes for 5.2-rc3

Here are some tiny USB fixes for a number of reported issues for
5.2-rc3.

Nothing huge here, just a small collection of xhci and other driver bugs
that syzbot has been finding in some drivers. There is also a usbip fix
and a fix for the usbip fix in here :)

All have been in linux-next with no reported issues.

This reverts most of commit b8eee0e90f97 ("lockd: Show pid of lockd for
remote locks"), which caused remote locks to not be differentiated between
remote processes for NLM.

We retain the fixup for setting the client's fl_pid to a negative value.

One significant one-liner fix is the disablement of the node-power

like the background noises or click noises on many devices.

Other than that, a fix for FireWire bit definitions, and another fix

net: correct zerocopy refcnt with udp MSG_MORE

TCP zerocopy takes a uarg reference for every skb, plus one for the
tcp_sendmsg_locked datapath temporarily, to avoid reaching refcnt zero
as it builds, sends and frees skbs inside its inner loop.

UDP and RAW zerocopy do not send inside the inner loop so do not need
the extra sock_zerocopy_get + sock_zerocopy_put pair. Commit
52900d22288ed ("udp: elide zerocopy operation in hot path") introduced
extra_uref to pass the initial reference taken in sock_zerocopy_alloc
to the first generated skb.

But, sock_zerocopy_realloc takes this extra reference at the start of
every call. With MSG_MORE, no new skb may be generated to attach the
extra_uref to, so refcnt is incorrectly 2 with only one skb.

Do not take the extra ref if uarg && !tcp, which implies MSG_MORE.
Update extra_uref accordingly.

This conditional assignment triggers a false positive may be used
uninitialized warning, so have to initialize extra_uref at define.

ethtool: Check for vlan etype or vlan tci when parsing flow_rule

When parsing an ethtool flow spec to build a flow_rule, the code checks
if both the vlan etype and the vlan tci are specified by the user to add
a FLOW_DISSECTOR_KEY_VLAN match.

However, when the user only specified a vlan etype or a vlan tci, this
check silently ignores these parameters.

For example, the following rule :

ethtool -N eth0 flow-type udp4 vlan 0x0010 action -1 loc 0

will result in no error being issued, but the equivalent rule will be
created and passed to the NIC driver :

ethtool -N eth0 flow-type udp4 action -1 loc 0

In the end, neither the NIC driver using the rule nor the end user have
a way to know that these keys were dropped along the way, or that
incorrect parameters were entered.

This kind of check should be left to either the driver, or the ethtool
flow spec layer.

This commit makes so that ethtool parameters are forwarded as-is to the
NIC driver.

Since none of the users of ethtool_rx_flow_rule_create are using the
VLAN dissector, I don't think this qualifies as a regression.

net-gro: fix use-after-free read in napi_gro_frags()

If a network driver provides to napi_gro_frags() an
skb with a page fragment of exactly 14 bytes, the call
to gro_pull_from_frag0() will 'consume' the fragment
by calling skb_frag_unref(skb, 0), and the page might
be freed and reused.

Reading eth->h_proto at the end of napi_frags_skb() might
read mangled data, or crash under specific debugging features.

Merge branch 'Fixes-for-DSA-tagging-using-802-1Q'

Vladimir Oltean says:

====================
Fixes for DSA tagging using 802.1Q

During the prototyping for the "Decoupling PHYLINK from struct
net_device" patchset, the CPU port of the sja1105 driver was moved to a
different spot. This uncovered an issue in the tag_8021q DSA code,
which used to work by mistake - the CPU port was the last hardware port
numerically, and this was masking an ordering issue which is very likely
to be seen in other drivers that make use of 802.1Q tags.

A question was also raised whether the VID numbers bear any meaning, and
the conclusion was that they don't, at least not in an absolute sense.
The second patch defines bit fields inside the DSA 802.1Q VID so that
tcpdump can decode it unambiguously (although the meaning is now clear
even by visual inspection).
