Then this code would be buggy too, there is no guarantee that a

Yes, _nowait is safe here (and needed, as you find out).

Can we enforce nodename to be mdio? That may not work for muxes.

thanks for the patch! We finally found an easy way to reproduce the deadlock,
the following commands instantly trigger the problem on our machines:
rmmod nf_conntrack_netlink
rmmod xfrm_user
conntrack -e NEW -E & modprobe -v xfrm_user
Note: the "-e" filter is needed to trigger the problematic
code path in the kernel.
We were worried that using "_nowait" would introduce other race conditions,
since the requested service might not be available by the time it is required.
On the other hand, if we understand correctly, it seems that after
"nfnetlink_bind()", the caller will listen on the socket for messages
regardless whether the needed modules are loaded, loading or unloaded.
To verify this we added a three second sleep during the initialisation of
nf_conntrack_netlink. The events started to appear after
the delayed init was completed.
If this is the case, then using "_nowait" should suffice as a fix
for the problem. Could you please confirm these assumptions
and give us some piece of mind?
Best regards,
Juliana Rodrigueiro and Thomas Jarosch

From: Stephen Hemminger @ 2019-06-27 15:33 UTC (permalink / raw)
To: netdev
This is on a very old kernel, and looks like not a valid bug.
But forwarding to list anyway since others may want to provide
input.
Begin forwarded message:
Date: Thu, 27 Jun 2019 09:33:27 +0000
From: bugzilla-daemon@bugzilla.kernel.org
To: stephen@networkplumber.org
Subject: [Bug 204005] New: Code in __mkroute_input isn't full correct
https://bugzilla.kernel.org/show_bug.cgi?id=204005
Bug ID: 204005
Summary: Code in __mkroute_input isn't full correct
Product: Networking
Version: 2.5
Kernel Version: 3.10.0-862
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: IPV4
Assignee: stephen@networkplumber.org
Reporter: cliff.chen@nokia-sbell.com
Regression: No
In function __mkroute_input(), there is issue in below code:
......
rt_cache:
if (rt_cache_valid(rth)) { <<======
skb_dst_set_noref(skb, &rth->dst);
goto out;
}
......
Once the route is failed, then rth.rt_type is set as unreachable(7).
however, once the route is correct again, because the condition
rt_cache_valid(rth) only check the rt_genid in cache and net space.
so even the route is recovery, then it always get the failed route cache.
one test env.
1) host1:
add ip1 on interface x
2) host2(proxy arp)
2.1) add ip2 on interface y1 with 32 prefix
2.2) add no IP on interface y2
Notes: x, y1 and y2 are in the same layer2 networkwork
set forwarding on y1 interface
set ip3 as arp proxy on interface y1
2.3) add ip3 on interface z on any interface which isn't the same layer2 as
interface y1 and y2.
3)run below test on host1 to check whether arp is back.
arping -I x -s ip1 ip3
The possible reason analysis:
since ARP is broadcast, then interface y2 can get this ARP request first,
because forwarding isn't set on on y2, then route failed. this is correct.
however, when ARP is received on y1, the route is always failed even the result
from fib_lookup is successfully. All these because the condition
rt_cache_valid(rth).
because, the rt_genid in cache isn't changed, and
rg_genid in network space isn't changed, too.
therefore, it will never OK until, I
down y2, or
ip route flush cache
to increase rt_genid in network space.
thanks
Cliff

Even though the DWMAC driver uses some driver specific properties, the PHY

Let's deprecate our specific properties.

The DWMAC specific properties to manage the PHY have been superseeded by
the generic PHY properties. Let's move to it.

Switch our Allwinner A20 GMAC controller binding to a YAML schema to enable
the DT validation. Since that controller is based on a Synopsys IP, let's
add the validation to that schemas with a bunch of conditionals.

be used in their device tree node. Add a YAML schemas for those.

-Common MDIO bus properties.
-
-These are generic properties that can apply to any MDIO bus.
-
-Optional properties:
-- reset-gpios: One GPIO that control the RESET lines of all PHYs on that MDIO
- bus.
-- reset-delay-us: RESET pulse width in microseconds.
-
-A list of child nodes, one per device on the bus is expected. These
-should follow the generic phy.txt, or a device specific binding document.
-
-The 'reset-delay-us' indicates the RESET signal pulse width in microseconds and
-applies to all PHY devices. It must therefore be appropriately determined based
-on all PHY requirements (maximum value of all per-PHY RESET pulse widths).

-Example :

-Fixed link Device Tree binding
-------------------------------
-
-Some Ethernet MACs have a "fixed link", and are not connected to a
-normal MDIO-managed PHY device. For those situations, a Device Tree
-binding allows to describe a "fixed link".
-
-Such a fixed link situation is described by creating a 'fixed-link'
-sub-node of the Ethernet MAC device node, with the following
-properties:
-
-* 'speed' (integer, mandatory), to indicate the link speed. Accepted
- values are 10, 100 and 1000
-* 'full-duplex' (boolean, optional), to indicate that full duplex is
- used. When absent, half duplex is assumed.
-* 'pause' (boolean, optional), to indicate that pause should be
- enabled.
-* 'asym-pause' (boolean, optional), to indicate that asym_pause should
- be enabled.
-* 'link-gpios' ('gpio-list', optional), to indicate if a gpio can be read
- to determine if the link is up.
-
-Old, deprecated 'fixed-link' binding:
-
-* A 'fixed-link' property in the Ethernet MAC node, with 5 cells, of the
- form <a b c d e> with the following accepted values:
- - a: emulated PHY ID, choose any but but unique to the all specified
- fixed-links, from 0 to 31
- - b: duplex configuration: 0 for half duplex, 1 for full duplex
- - c: link speed in Mbits/sec, accepted values are: 10, 100 and 1000
- - d: pause configuration: 0 for no pause, 1 for pause
- - e: asymmetric pause configuration: 0 for no asymmetric pause, 1 for
- asymmetric pause
-
-Examples:
-
-ethernet@0 {
- ...
- fixed-link {
- speed = <1000>;
- full-duplex;
- };
- ...
-};
-
-ethernet@1 {
- ...
- fixed-link {
- speed = <1000>;
- pause;
- link-gpios = <&gpio0 12 GPIO_ACTIVE_HIGH>;
- };
- ...

Switch our Allwinner H3 EMAC controller binding to a YAML schema to enable
the DT validation. Since that controller is based on a Synopsys IP, let's
add the validation to that schemas with a bunch of conditionals.

* [PATCH v4 00/13] net: Add generic and Allwinner YAML bindings
From: Maxime Ripard @ 2019-06-27 15:31 UTC (permalink / raw)

Hi,
This is an attempt at getting the main generic DT bindings for the ethernet
(and related) devices, and convert some DT bindings for the Allwinner DTs
to YAML as well.
This should provide some DT validation coverage.
Let me know if you have any questions,
Maxime
Changes from v3:
- Added a cover letter
- Dropped the phy-mode deprecation, and the DT changes moving to
phy-connection-type
- Fixed the mdio example node name
- Deprecated the fixed-link array property, in favor of the fixed-link
subnode
Changes from v2:
- Switched to the deprecated keyword to describe deprecated properties
- Deprecated phy-mode, phy and phy-handle
- Added patches to switch to phy-connection-type and phy-device for
Allwinner DTs
- Changed the A83t GMAC delays to use multipleOf instead of an enum
- Fix the snps,*pbl properties types
- Add a generic MDIO YAML schemas
Changes from v1:
- Move the DWMAC SoC specific bindings to separate documents
- Mark snps,reset-gpio (and related) as deprecated and fixed the
Allwinner DTs accordingly
- Restrict snps,tso to only a couple of compatibles
- Use an enum for the compatibles
- Add a custom select statement with the compatibles of all the generic
compatibles, including the deprecated ones. Remove the deprecated ones
from the valid compatible values to issue a warning when used.
- Add a patch to MAINTAINERS for the PHY YAML binding
- Add missing compatible options for the PHY, and missing phy speeds
- Add a custom select clause to make the PHY binding validate all phy
nodes, and not just the ones with a compatible
- Validate the fixed-link array elements
- Removed deprecated properties (phy-mode, phy, phy-device)
- Restrict the number of items under link-gpios to 1

I looked into this in the past, but then rejected it because
there are so many tools that use names, not just iproute2.
Plus long names are very user unfriendly.

* [PATCH net] selftests: rtnetlink: skip ipsec offload tests if netdevsim isn't present
From: Florian Westphal @ 2019-06-27 15:12 UTC (permalink / raw)
To: netdev; +Cc: Florian Westphal
running the script on systems without netdevsim now prints:
SKIP: ipsec_offload can't load netdevsim
instead of error message & failed status.
Signed-off-by: Florian Westphal <fw@strlen.de>

Feel free to apply to -next, its not a bug fix per se.
