We definitely don't want to bring over the vendor code, since it's a
pile of spaghetti, but we probably need to get something sorted. This
went down the drain when the bluetooth driver was added without taking
it into account - long after this driver was merged.

This part I would like to ask you take a good look at the other chips to
make sure you don't break support for 8192cu, 8723au, 8188eu with this.

Hello, the parameter  ETH_MAX_PACKET limited to 1500 bytes is the not

Thank you for the review!

You are right, that declaration can be dropped.

Uhm... since inet6_{send,recv}msg exists only for retpoline sake and
are not exported, I think is probably better move their declaration to
socket.c via INDIRECT_CALLABLE_DECLARE(), to that ICWs are all self-
contained.

Unless there are objections about spamming, I can repost the series
with the above changes.

if (ret)

Same remark goes to the rest of the code (also the rest of the patches),
in case called function cannot return positive values.

Just:
	req_info->req_mask = nla_get_u32(tb[ETHTOOL_A_HEADER_INFOMASK];
	...

Not sure what ethnl_update_u32() is good for, but it is not needed here.

If you really need this helper, put it into netlink code. There's nothing
ethtool-specific about this.

I wonder why you need this helper. Genetlink uses

* Memory leaks in IPv6 ndisc on v4.19.56
From: Martin Weinelt @ 2019-07-02 13:05 UTC (permalink / raw)
  To: David S. Miller, Alexey Kuznetsov, Hideaki YOSHIFUJI, netdev

[-- Attachment #1: Type: text/plain, Size: 1507 bytes --]

Hi everyone,

I've been experiencing memory leaks on the v4.19 series. I've started
seeing them on Debian with v4.19.16 and I can reproduce them on v4.19.56
using Debians kernel config. I was unable to reproduce this on 
v5.2.0-rc6/rc7.

  [ 1899.380321] kmemleak: 1138 new suspected memory leaks (see /sys/kernel/debug/kmemleak)

On the machines in question we're running routers for a mesh networking
setup based on the batman-adv kmod. Our setup consists of KVM guests 
running Debian, with each router having 18 bridges with the following
master/slave relationship:

  bridge -> batman-adv -> {L2 tunnel, virtio net device}

I've attached the output of kmemleak and I've looked up the top-most
function offsets below:

Best,
  Martin

* [PATCH] nfc: st-nci: remove redundant assignment to variable r
From: Colin King @ 2019-07-02 13:16 UTC (permalink / raw)
  To: Thomas Gleixner, netdev; +Cc: kernel-janitors, linux-kernel

From: Colin Ian King <colin.king@canonical.com>

The variable r is being initialized with a value that is never
read and it is being updated later with a new value. The
initialization is redundant and can be removed.

This is very much *NOT* fine.
	1) trylock can fail from any number of reasons, starting
with "somebody is going through the hash chain doing a lookup on
something completely unrelated"
	2) whoever had been holding the lock and whatever they'd
been doing might be over right after we get the return value from
spin_trylock().
	3) even had that been really somebody adding children in
the same parent *AND* even if they really kept doing that, rather
than unlocking and buggering off, would you care to explain why
dentry_unlist() called by __dentry_kill() and removing the victim
from the list of children would be safe to do in parallel with that?

NAK, in case it's not obvious from the above.

* [PATCH bpf-next] bpf: cgroup: Fix build error without CONFIG_NET

This might not be the correct bisection point.  If you look at the attached
sample, you're mixing AF_INET and AF_INET6.  If you try AF_INET throughout,
that might get a different point.  On the other hand, since you've bound the
socket, the AF_INET6 passed to socket() should be ignored.

I will try to create a cleaned-up version of your patch[1] and
re-introduce page_pool_destroy() for drivers to use, then we can build
your driver on top of that.

As far as I understood (correct me if I'm wrong), you are trying to 
preserve backward compatibility, so that if userspace doesn't support 
the flags field, you will determine that by looking at len and fall back 
to the old format.

However, two things are broken here:

1. The check `len < sizeof(off) - sizeof(off.rx.flags)` should be `len < 
sizeof(off) - 4 * sizeof(flags)`, because struct xdp_mmap_offsets 
consists of 4 structs xdp_ring_offset.

2. The old and new formats are not binary compatible, as flags are 
inserted in the middle of struct xdp_mmap_offsets.

Thanks Jianwen, this is kinda expected, since I left out the
SIOCDELTUNNEL case in my code.

While this can be easily fixed, the intent of the offending patch is
not entirely clear to me.

From the ip tunnel man page, I can read that with "dev NAME" we
instruct ip to bind the tunnel to the device NAME; so dev should not
be used to indicate the tunnel, as the offending commit does.
Moreover, man page states that "ip tunnel show" has no arguments. So,
either we update the man page fixing this obsolete statement, or the
"show dev NAME" case is not supported at all.
However, even if "show" command supports filter (as it seems to do),
in my opinion "dev NAME" should be used to filter tunnels based on the
device to which they are binded.

Mahesh, can you please clarify?

Regards,
Andrea

That was the intention yes.

You are correct. Since there are four copies of the xdp_ring_offset
this simple scheme will not work. I will instead create an internal
version 1 of the struct that I fill in and pass to user space if I
detect that user space is asking for the v1 size.

Thanks for catching Maxim. Keep'em coming.

Do you mean a large "XDP" metadata? If a large metadata is a large "XDP" metadata, I think we can not use a metadata that occupies all headroom. The size of metadata limited by bpf_xdp_adjust_meta() as below.
bpf_xdp_adjust_meta() in net/core/filter.c:
	if (unlikely((metalen & (sizeof(__u32) - 1)) ||
		     (metalen > 32)))
		return -EACCES;

I've corrected patch to xdp core and tested. The "page pool API" change
seems is orthogonal now. So no limits to send v6 that is actually done
and no more strict dependency on page pool API changes whenever that
can happen.

Indeed, also you could create the bridge with explicit mcast parameters if you need
different behaviour on start. Unfortunately I think you'll have to handle
the querier state.

* [PATCH] net: core: page_pool: add user refcnt and reintroduce page_pool_destroy
From: Jesper Dangaard Brouer @ 2019-07-02 14:31 UTC (permalink / raw)
  To: netdev, Ilias Apalodimas, ivan.khoronzhuk, Jesper Dangaard Brouer
  Cc: grygorii.strashko, jakub.kicinski, daniel, john.fastabend, ast,
	linux-kernel, linux-omap
In-Reply-To: <20190702153902.0e42b0b2@carbon>

From: Ivan Khoronzhuk <ivan.khoronzhuk@linaro.org>

Jesper recently removed page_pool_destroy() (from driver invocation) and
moved shutdown and free of page_pool into xdp_rxq_info_unreg(), in-order to
handle in-flight packets/pages. This created an asymmetry in drivers
create/destroy pairs.

This patch add page_pool user refcnt and reintroduce page_pool_destroy.
This serves two purposes, (1) simplify drivers error handling as driver now
drivers always calls page_pool_destroy() and don't need to track if
xdp_rxq_info_reg_mem_model() was unsuccessful. (2) allow special cases
where a single RX-queue (with a single page_pool) provides packets for two
net_device'es, and thus needs to register the same page_pool twice with two
xdp_rxq_info structures.

This patch is a modified version of Ivan Khoronzhuk's original patch.
Thus, Jesper gives author ownership to Ivan.
