Re: PATCH 1/1] AX.25: Close socket connection on session completion

Hello David,

I don't have a specific commit # for you at the moment but there have been a few serious regressions since 4.1.x.  When new code gets commited, are there any systems to run regession tests on?  I'd be willing to build up a pair of VMs that can be run with scripts to verify say basic sanity for kissattach, ax.25, netrom, rose, etc.

Btw, once I get back, I hope to pursue some additional negative case fixes:  (pulling a usb-to-serial adapter when used with kiss-attach will panic the kernel, ifconfig rose0 down will take the kernel to 100%, and a data corruption issue for large transfers (2MB+).

Thanks for your help!

A socket connection made in ax.25 is not closed when session is
completed.  The heartbeat timer is stopped prematurely and this is
where the socket gets closed. Allow heatbeat timer to run to close
socket. Symptom occurs in kernels >= 4.2.0

What changed in 4.2.x that broke this?
