In the Linux kernel, the following vulnerability has been resolved:

ax25: fix incorrect dev_tracker usage

While investigating a separate rose issue [1], and enabling CONFIG_NET_DEV_REFCNT_TRACKER=y, Bernard reported an orthogonal ax25 issue [2]

An ax25_dev can be used by one (or many) struct ax25_cb. We thus need different dev_tracker, one per struct ax25_cb.

After this patch is applied, we are able to focus on rose.
