Add dl_type to flow metadata for correct interpretation of conntrack metadata
When a packet is sent to the controller, dl_type is not stored in the
'ofputil_packet_in_private'. When the packet is resumed, the flow's
dl_type is 0 and this leads to invalid value in ct_orig_tuple in the
pkt_metadata.
This patch adds the dl_type to the metadata so that conntrack
information can be interpreted correctly when packets are resumed.
This is a change from the ordinary practice, since flow_get_metadata() is
only supposed to deal with metadata and dl_type is not metadata. It is
necessary when ct_state is involved, though, because ct_state only applies
in the case of particular Ethertypes (IPv4 and IPv6 currently), so we need
to add it as a kind of prerequisite. (This isn't ideal; maybe we didn't
think through the ct_state mechanism carefully enough.)

the controller resumes (OFPRAW_NXT_RESUME) the packet, the flow's dl_type will be

Conntrack, Conntrack-related, Stt, and IP fragmentation
have cleaner threads that run periodically to clean
up their respective tables. During driver unload,
OvsExtDetach() calls into routines that are meant
for explicitly cleaning these tables up and freeing
the resources associated with these threads.
If during driver unload, these cleaner threads run
immediately after the resources are freed, such as locks
used by these threads, then the cleaner threads result
in a kernel crash since they try to acquire locks
that have already been freed.
For eg, OvsIpFragmentEntryCleaner() caused a kernel
crash because it tried to acquire a lock that was
already freed by OvsCleanupIpFragment().
The fix is to simply exit the cleaner thread if the
lock associated with the thread is not initialized,
because the only way the threads can run when the lock
is invalid is when the lock has been freed up during
driver unload.
Testing done:
Verified that cleaner threads run as expected without
crashing during driver unload.

an intentional exploit, unintentional problem or just a rare
condition. The solution is to keep track of reverse conn via
nat_conn_keys and avoid deleting the reverse conn when it has been
recreated.

Given that it is libopenvswitch-dev not libopenvswitch that depends on
libssl-dev, this patch updates debian/control file to reflect that
libopenvswitch-dev depends on libssl-dev, and libopenvswitch depends
on openssl.

datapath: Fix up vxlan device flags
I missed a couple of usages of the flags parameter from vxlan_dev
while adding compatibility code to handle the removal of the flags.
Add the checks so that the module can compile for Linux kernel
release 4.13

datapath: Fixup RTNL ops for kernel 4.13
The RTNL ops validate and newlink functions now take the extended
netlink ack parameter. Use the new HAVE_EXT_ACK_IN_RTNL_LINKOPS
define to check if the additional parameter is present and add the
parameter if so.
While in the modules remove the checks for Linux kernels < 2.3.39
since they are no longer supported since 2.5.x.
