Hi,
Tried to connect to sw vpn today, and it isn't working. Running git
as-of yesterday. In dmesg:
[23703.921542] vpn0: set_features() failed (-1); wanted
0x00000080000048c1, left 0x00000080001b48c9
Reverting:
fd867d51f889
5ba3f7d61a3a
e7868a85e1b2
in reverse order makes it work again. How do we get this fixed so that
4.4-rc1 doesn't break basic VPN support?
