Base vector

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

netfilter: ebtables: move to two-stage removal scheme

Like previous patches for x tables, follow same pattern in ebtables. We can't reuse xt helpers: ebt table struct layout is incompatible.

table->ops assignment is now done while still holding the ebt mutex to make sure we never expose partially-filled table struct.
