Conditional locking, especialy such extensive use of conditional
locking as is being done here, is strongly discouraged and is always
indicative of bad design.
Please try to rework this change such that the code paths that want
to lock things a certain way are %100 segregated functionally into
different code paths and functions.
Or feel free to find a cleaner way to fix this.

I don't understand how a netfilter config options is going to make that
generic ipv4 protocol per-device sysctl appear.
If it's unrelated to your change, don't include it in the commit message

Sorry, no.
The SKB extensions are not a dumping ground for people to use when they can't
figure out another more reasonable place to put their values. Try to use
the normal cb[], and if you can't you must explain in exhaustive detail
why you cannot in any way whatsoever make that work.
Again, SKB extensions are not a dumping ground.

I honestly don't know, I kinda feared that once the SKB extension went in
people would start dumping things there and that's exactly what's happening.

I would be okay with only adding a skb extension when we needed it,
which I'm currently thinking would only be when we had labeled
networking actually configured at runtime and not just built into the
kernel. In SELinux we do something similar today when it comes to our
per-packet access controls; if labeled networking is not configured we
bail out of the LSM hooks early to improve performance (we would just
be comparing unlabeled_t to unlabeled_t anyway). I think the other
LSMs would be okay with this usage as well.
While a number of distros due enable some form of LSM and the labeled
networking bits at build time, vary few (if any?) provide a default
configuration so I would expect no additional overhead in the common
case.
Would that be acceptable?

Looks to be:
#syz dup: BUG: MAX_STACK_TRACE_ENTRIES too low! (2)
Original thread: https://lkml.kernel.org/lkml/0000000000005ff8b20585395280@google.com/T/#u
The caller isn't really meaningful for "MAX_STACK_TRACE_ENTRIES too low" bugs,
so I think
https://github.com/google/syzkaller/pull/1332/commits/ccbd11f30158d198e84953b1bb5eaa33464d9311
should be reverted...

Hi Yang:
I think maybe we can try to hold refcnt instead of playing real num
queues here. Do you want to post a V4?

* [PATCH net] openvswitch: Fix conntrack cache with timeout
From: Yi-Hung Wei @ 2019-08-22 0:14 UTC (permalink / raw)
To: netdev, pshelar; +Cc: Yi-Hung Wei
This patch addresses a conntrack cache issue with timeout policy.
Currently, we do not check if the timeout extension is set properly in the
cached conntrack entry. Thus, after packet recirculate from conntrack
action, the timeout policy is not applied properly. This patch fixes the
aforementioned issue.

* [PATCH net] net: dsa: bcm_sf2: Do not configure PHYLINK on CPU port
From: Florian Fainelli @ 2019-08-22 0:07 UTC (permalink / raw)
To: netdev
Cc: Florian Fainelli, Andrew Lunn, Vivien Didelot, David S. Miller,
open list
The SF2 binding does not specify that the CPU port should have
properties mandatory for successfully instantiating a PHYLINK object. As
such, there will be missing properties (including fixed-link) and when
attempting to validate and later configure link modes, we will have an
incorrect set of parameters (interface, speed, duplex).
Simply prevent the CPU port from being configured through PHYLINK since
bcm_sf2_imp_setup() takes care of that already.
Fixes: 0e27921816ad ("net: dsa: Use PHYLINK for the CPU/DSA ports")

Thank you. I would, but that is not available on the system under test, while ifconfig is.
