Bug #162

"INFO: possible recursive locking detected"
Added by Linus Lüssing over 12 years ago.

Description
Using a 3.4.0 kernel (Linux mesh-node1 3.4.0 #1 SMP PREEMPT Thu Jul 19 20:17:49 BST 2012 i686 GNU/Linux) in kvm with a few debug options and two nodes A and B connected via a single interface results in the attached traces as soon as A tries to ping B. After a 750ms lag the ICMP packets travel through fine though.
Tried batman-adv v2011.3.0, v2012.0.0 and master 3fdeaa6bfb404311b73a689e984672161403a0c2, all with the same issue (the attached traces are from the master branch).

Hello, I'm sorry but I hit this stack trace again while testing latest master...
My setup is made up by 4 VMs interconnected like a chain (node1<->node2<->node3<->node4).
I get the stack trace when I ping node 1 from a client bridged in node 2.
By the way this is strange because I remember that the bug went away while testing Simon's patch. Maybe something added later has recreated the problem? I'll try to bisect.
Hm, just noticed that with v2012.4.0 I'm having these messages again. Were those patches (commit:b8f86c91faeb816168ecbdac0a355f316781ba77, commit:e27bb6fa916451e9eaced16e7c21d5b71a3b7f30) accidentally forgotten to be included in v2012.4.0 or were they kept back on purpose due to this issue still being reproducable in certain scenarios even with these patches?
These patches are non-critical and therefore were applied on top of master. As result, these patches were now sent to David and will be part of the 2012.5.0 release.
