Hi guys,
Send a pull request with that try_lock movement fix based on the former tests:
https://github.com/openvswitch/ovs/pull/421
Does that make sense to you?
Thank you.

No more core was seen during that revalidator_sweep__ procedure for 4 days now.
But if I revert this lock movement, the core can show again in a few hours.
So, please take a look at this lock movement patch, if it make sense to you.

Right?
If it is true, I will update the buffer structure, and a
counter_upcall_ukey_allocate as well.

@Ilya, thank you, I will add that patch.
@Eelco, thank you again, I will add a RL log to the free(ukey). Hope
we can get something useful.

For last mail, can this issue be concurrent read-and-update/delete?
The revalidator_sweep__ is trying to lock the ukey->mutex, while
another thread is updating the ukey->mutex to NULL and free ukey.

CMIIW, if this race condition can happen, IMO, it is mostly because

There seems to be an out-of-bounds access to the linked list of ukeys here.
So, I would greatly appreciate your help, as it is crucial for OVS to operate
in our production environment.
I can provide further debug related output information at any time.
Waiting for your response...
Thank you very much in advance.

May I ask if everyone can provide a preliminary evaluation of the
problem? How could this happen? And what can we do to work around the
problem?

Action "mod_nw_tos:" is causing the error here.
So, I would ask which action for OPENFLOW13 is to do same work of
"mod_nw_tos:" for OPENFLOW10? These is no doc mentioned such action
for OPENFLOW13.

Hi experts,
We have failed to build Open vSwitch Kernel Modules on CentOS 7 (kernel
3.10.0-514.2.2.el7.x86_64).
Here are some traces we got:

Steps:
1. download the current openvswitch release:
