      net/usb: mark LG VL600 LTE modem ethernet interface as WWAN · aae1e743
      Dan Williams authored 
      Like other mobile broadband device ethernet interfaces, mark the LG
VL600 with the 'wwan' devtype so userspace knows it needs additional
configuration via the AT port before the interface can be used.

      xfrm: Don't allow esn with disabled anti replay detection · 6fa5ddcc
      Steffen Klassert authored 
      Unlike the standard case, disabled anti replay detection needs some
nontrivial extra treatment on ESN. RFC 4303 states:

Note: If a receiver chooses to not enable anti-replay for an SA, then
the receiver SHOULD NOT negotiate ESN in an SA management protocol.
Use of ESN creates a need for the receiver to manage the anti-replay
window (in order to determine the correct value for the high-order
bits of the ESN, which are employed in the ICV computation), which is
generally contrary to the notion of disabling anti-replay for an SA.

So return an error if an ESN state with disabled anti replay detection
is inserted for now and add the extra treatment later if we need it.

      xfrm: Assign the inner mode output function to the dst entry · 43a4dea4
      Steffen Klassert authored 
      As it is, we assign the outer modes output function to the dst entry
when we create the xfrm bundle. This leads to two problems on interfamily
scenarios. We might insert ipv4 packets into ip6_fragment when called
from xfrm6_output. The system crashes if we try to fragment an ipv4
packet with ip6_fragment. This issue was introduced with git commit
ad0081e4 (ipv6: Fragment locally generated tunnel-mode IPSec6 packets
as needed). The second issue is, that we might insert ipv4 packets in
netfilter6 and vice versa on interfamily scenarios.

With this patch we assign the inner mode output function to the dst entry
when we create the xfrm bundle. So xfrm4_output/xfrm6_output from the inner
mode is used and the right fragmentation and netfilter functions are called.
We switch then to outer mode with the output_finish functions.

      net: dev_close() should check IFF_UP · e14a5993
      Eric Dumazet authored 
      Commit 44345724 (factorize sync-rcu call in
unregister_netdevice_many) mistakenly removed one test from dev_close()

Following actions trigger a BUG :

modprobe bonding
modprobe dummy
ifconfig bond0 up
ifenslave bond0 dummy0
rmmod dummy

dev_close() must not close a non IFF_UP device.

We should call vlan_gvrp_request_leave() from unregister_vlan_dev(),
not from vlan_dev_stop(), because vlan_gvrp_uninit_applicant()
is called right after unregister_netdevice_queue(). In batch mode,
unregister_netdevice_queue() doesn’t immediately call vlan_dev_stop().
