Pablo Neira Ayuso cf23d531a9 netfilter: nf_tables: reject duplicate device on updates 
commit cf5fb87fcd upstream.

A chain/flowtable update with duplicated devices in the same batch is
possible. Unfortunately, netdev event path only removes the first
device that is found, leaving unregistered the hook of the duplicated
device.

Check if a duplicated device exists in the transaction batch, bail out
with EEXIST in such case.

WARNING is hit when unregistering the hook:

 [49042.221275] WARNING: CPU: 4 PID: 8425 at net/netfilter/core.c:340 nf_hook_entry_head+0xaa/0x150

 [...]
 [49042.221382] RIP: 0010:nf_hook_entry_head+0xaa/0x150

Fixes: b9703ed44f ("netfilter: nf_tables: support for adding new devices to an existing netdev chain")
