5. IPX
------
The IPX protocol has no tunable values in proc/sys/net.
The IPX protocol does, however, provide proc/net/ipx. This lists each IPX
socket giving the local and remote addresses in Novell format (that is
network:node:port). In accordance with the strange Novell tradition,
everything but the port is in hex. Not_Connected is displayed for sockets that
are not tied to a specific remote address. The Tx and Rx queue sizes indicate
the number of bytes pending for transmission and reception. The state
indicates the state the socket is in and the uid is the owning uid of the
socket.
The /proc/net/ipx_interface file lists all IPX interfaces. For each interface
it gives the network number, the node number, and indicates if the network is
the primary network. It also indicates which device it is bound to (or
Internal for internal networks) and the Frame Type if appropriate. Linux
supports 802.3, 802.2, 802.2 SNAP and DIX (Blue Book) ethernet framing for
IPX.
The /proc/net/ipx_route table holds a list of IPX routes. For each route it
gives the destination network, the router node (or Directly) and the network
address of the router (or Connected) for internal networks.

These flags will be acted upon accordingly by the core ``ktls`` code.
TLS device feature flags only control adding of new TLS connection

Known bugs
==========
skb_orphan() leaks clear text
-----------------------------
Currently drivers depend on the :c:member:`sk` member of
:c:type:`struct sk_buff <sk_buff>` to identify segments requiring
encryption. Any operation which removes or does not preserve the socket
association such as :c:func:`skb_orphan` or :c:func:`skb_clone`
will cause the driver to miss the packets and lead to clear text leaks.
Redirects leak clear text
-------------------------
In the RX direction, if segment has already been decrypted by the device
and it gets redirected or mirrored - clear text will be transmitted out.
