==================
Kernel TLS offload
==================
Kernel TLS operation
====================
Linux kernel provides TLS connection offload infrastructure. Once a TCP
connection is in ``ESTABLISHED`` state user space can enable the TLS Upper
Layer Protocol (ULP) and install the cryptographic connection state.
For details regarding the user-facing interface refer to the TLS
documentation in :ref:`Documentation/networking/tls.rst <kernel_tls>`.
``ktls`` can operate in three modes:
* Software crypto mode (``TLS_SW``) - CPU handles the cryptography.
In most basic cases only crypto operations synchronous with the CPU
can be used, but depending on calling context CPU may utilize
asynchronous crypto accelerators. The use of accelerators introduces extra
latency on socket reads (decryption only starts when a read syscall
is made) and additional I/O load on the system.
* Packet-based NIC offload mode (``TLS_HW``) - the NIC handles crypto
on a packet by packet basis, provided the packets arrive in order.
This mode integrates best with the kernel stack and is described in detail
in the remaining part of this document
(``ethtool`` flags ``tls-hw-tx-offload`` and ``tls-hw-rx-offload``).
* Full TCP NIC offload mode (``TLS_HW_RECORD``) - mode of operation where
NIC driver and firmware replace the kernel networking stack
with its own TCP handling, it is not usable in production environments
making use of the Linux networking stack for example any firewalling
abilities or QoS and packet scheduling (``ethtool`` flag ``tls-hw-record``).
The operation mode is selected automatically based on device configuration,
offload opt-in or opt-out on per-connection basis is not currently supported.
TX
--
At a high level user write requests are turned into a scatter list, the TLS ULP
intercepts them, inserts record framing, performs encryption (in ``TLS_SW``
mode) and then hands the modified scatter list to the TCP layer. From this
point on the TCP stack proceeds as normal.
In ``TLS_HW`` mode the encryption is not performed in the TLS ULP.
Instead packets reach a device driver, the driver will mark the packets
for crypto offload based on the socket the packet is attached to,
and send them to the device for encryption and transmission.
RX
--
On the receive side if the device handled decryption and authentication
successfully, the driver will set the decrypted bit in the associated
:c:type:`struct sk_buff <sk_buff>`. The packets reach the TCP stack and
are handled normally. ``ktls`` is informed when data is queued to the socket
and the ``strparser`` mechanism is used to delineate the records. Upon read
request, records are retrieved from the socket and passed to decryption routine.
If device decrypted all the segments of the record the decryption is skipped,
otherwise software path handles decryption.
.. kernel-figure:: tls-offload-layers.svg
:alt: TLS offload layers
:align: center
:figwidth: 28em
Layers of Kernel TLS stack
Device configuration
====================
During driver initialization device sets the ``NETIF_F_HW_TLS_RX`` and
``NETIF_F_HW_TLS_TX`` features and installs its
:c:type:`struct tlsdev_ops <tlsdev_ops>`
pointer in the :c:member:`tlsdev_ops` member of the
:c:type:`struct net_device <net_device>`.
When TLS cryptographic connection state is installed on a ``ktls`` socket
(note that it is done twice, once for RX and once for TX direction,
and the two are completely independent), the kernel checks if the underlying
network device is offload-capable and attempts the offload. In case offload
fails the connection is handled entirely in software using the same mechanism
as if the offload was never tried.
Offload request is performed via the :c:member:`tls_dev_add` callback of
:c:type:`struct tlsdev_ops <tlsdev_ops>`:
.. code-block:: c
int (*tls_dev_add)(struct net_device *netdev, struct sock *sk,
enum tls_offload_ctx_dir direction,
struct tls_crypto_info *crypto_info,
u32 start_offload_tcp_sn);
``direction`` indicates whether the cryptographic information is for
the received or transmitted packets. Driver uses the ``sk`` parameter
to retrieve the connection 5-tuple and socket family (IPv4 vs IPv6).
Cryptographic information in ``crypto_info`` includes the key, iv, salt
as well as TLS record sequence number. ``start_offload_tcp_sn`` indicates
which TCP sequence number corresponds to the beginning of the record with
sequence number from ``crypto_info``. The driver can add its state
at the end of kernel structures (see :c:member:`driver_state` members
in ``include/net/tls.h``) to avoid additional allocations and pointer
dereferences.
TX
--
After TX state is installed, the stack guarantees that the first segment
of the stream will start exactly at the ``start_offload_tcp_sn`` sequence
number, simplifying TCP sequence number matching.
TX offload being fully initialized does not imply that all segments passing
through the driver and which belong to the offloaded socket will be after
the expected sequence number and will have kernel record information.
In particular, already encrypted data may have been queued to the socket
before installing the connection state in the kernel.
RX
--
In RX direction local networking stack has little control over the segmentation,
so the initial records' TCP sequence number may be anywhere inside the segment.
Normal operation
================
At the minimum the device maintains the following state for each connection, in
each direction:
* crypto secrets (key, iv, salt)
* crypto processing state (partial blocks, partial authentication tag, etc.)
* record metadata (sequence number, processing offset and length)
* expected TCP sequence number
There are no guarantees on record length or record segmentation. In particular
segments may start at any point of a record and contain any number of records.
Assuming segments are received in order, the device should be able to perform
crypto operations and authentication regardless of segmentation. For this
to be possible device has to keep small amount of segment-to-segment state.
This includes at least:
* partial headers (if a segment carried only a part of the TLS header)
* partial data block
* partial authentication tag (all data had been seen but part of the
authentication tag has to be written or read from the subsequent segment)
Record reassembly is not necessary for TLS offload. If the packets arrive
in order the device should be able to handle them separately and make
forward progress.
TX
--
The kernel stack performs record framing reserving space for the authentication
tag and populating all other TLS header and tailer fields.
Both the device and the driver maintain expected TCP sequence numbers
due to the possibility of retransmissions and the lack of software fallback
once the packet reaches the device.
For segments passed in order, the driver marks the packets with
a connection identifier (note that a 5-tuple lookup is insufficient to identify
packets requiring HW offload, see the :ref:`5tuple_problems` section)
and hands them to the device. The device identifies the packet as requiring
TLS handling and confirms the sequence number matches its expectation.
The device performs encryption and authentication of the record data.
It replaces the authentication tag and TCP checksum with correct values.
RX
--
Before a packet is DMAed to the host (but after NIC's embedded switching
and packet transformation functions) the device validates the Layer 4
checksum and performs a 5-tuple lookup to find any TLS connection the packet
may belong to (technically a 4-tuple
lookup is sufficient - IP addresses and TCP port numbers, as the protocol
is always TCP). If connection is matched device confirms if the TCP sequence
number is the expected one and proceeds to TLS handling (record delineation,
decryption, authentication for each record in the packet). The device leaves
the record framing unmodified, the stack takes care of record decapsulation.
Device indicates successful handling of TLS offload in the per-packet context
(descriptor) passed to the host.
Upon reception of a TLS offloaded packet, the driver sets
the :c:member:`decrypted` mark in :c:type:`struct sk_buff <sk_buff>`
corresponding to the segment. Networking stack makes sure decrypted
and non-decrypted segments do not get coalesced (e.g. by GRO or socket layer)
and takes care of partial decryption.
Resync handling
===============
In presence of packet drops or network packet reordering, the device may lose
synchronization with the TLS stream, and require a resync with the kernel's
TCP stack.
Note that resync is only attempted for connections which were successfully
added to the device table and are in TLS_HW mode. For example,
if the table was full when cryptographic state was installed in the kernel,
such connection will never get offloaded. Therefore the resync request
does not carry any cryptographic connection state.
TX
--
Segments transmitted from an offloaded socket can get out of sync
in similar ways to the receive side-retransmissions - local drops
are possible, though network reorders are not.
Whenever an out of order segment is transmitted the driver provides
the device with enough information to perform cryptographic operations.
This means most likely that the part of the record preceding the current
segment has to be passed to the device as part of the packet context,
together with its TCP sequence number and TLS record number. The device
can then initialize its crypto state, process and discard the preceding
data (to be able to insert the authentication tag) and move onto handling
the actual packet.
In this mode depending on the implementation the driver can either ask
for a continuation with the crypto state and the new sequence number
(next expected segment is the one after the out of order one), or continue
with the previous stream state - assuming that the out of order segment
was just a retransmission. The former is simpler, and does not require
retransmission detection therefore it is the recommended method until
such time it is proven inefficient.
RX
--
A small amount of RX reorder events may not require a full resynchronization.
In particular the device should not lose synchronization
when record boundary can be recovered:
.. kernel-figure:: tls-offload-reorder-good.svg
:alt: reorder of non-header segment
:align: center
Reorder of non-header segment
Green segments are successfully decrypted, blue ones are passed
as received on wire, red stripes mark start of new records.
In above case segment 1 is received and decrypted successfully.
Segment 2 was dropped so 3 arrives out of order. The device knows
the next record starts inside 3, based on record length in segment 1.
Segment 3 is passed untouched, because due to lack of data from segment 2
the remainder of the previous record inside segment 3 cannot be handled.
The device can, however, collect the authentication algorithm's state
and partial block from the new record in segment 3 and when 4 and 5
arrive continue decryption. Finally when 2 arrives it's completely outside
of expected window of the device so it's passed as is without special
handling. ``ktls`` software fallback handles the decryption of record
spanning segments 1, 2 and 3. The device did not get out of sync,
even though two segments did not get decrypted.
Kernel synchronization may be necessary if the lost segment contained
a record header and arrived after the next record header has already passed:
.. kernel-figure:: tls-offload-reorder-bad.svg
:alt: reorder of header segment
:align: center
Reorder of segment with a TLS header
In this example segment 2 gets dropped, and it contains a record header.
Device can only detect that segment 4 also contains a TLS header
if it knows the length of the previous record from segment 2. In this case
the device will lose synchronization with the stream.
When the device gets out of sync and the stream reaches TCP sequence
numbers more than a max size record past the expected TCP sequence number,
the device starts scanning for a known header pattern. For example
for TLS 1.2 and TLS 1.3 subsequent bytes of value ``0x03 0x03`` occur
in the SSL/TLS version field of the header. Once pattern is matched
the device continues attempting parsing headers at expected locations
(based on the length fields at guessed locations).
Whenever the expected location does not contain a valid header the scan
is restarted.
When the header is matched the device sends a confirmation request
to the kernel, asking if the guessed location is correct (if a TLS record
really starts there), and which record sequence number the given header had.
The kernel confirms the guessed location was correct and tells the device
the record sequence number. Meanwhile, the device had been parsing
and counting all records since the just-confirmed one, it adds the number
of records it had seen to the record number provided by the kernel.
At this point the device is in sync and can resume decryption at next
segment boundary.
In a pathological case the device may latch onto a sequence of matching
headers and never hear back from the kernel (there is no negative
confirmation from the kernel). The implementation may choose to periodically
restart scan. Given how unlikely falsely-matching stream is, however,
periodic restart is not deemed necessary.
Special care has to be taken if the confirmation request is passed
asynchronously to the packet stream and record may get processed
by the kernel before the confirmation request.
Error handling
==============
TX
--
Packets may be redirected or rerouted by the stack to a different
device than the selected TLS offload device. The stack will handle
such condition using the :c:func:`sk_validate_xmit_skb` helper
(TLS offload code installs :c:func:`tls_validate_xmit_skb` at this hook).
Offload maintains information about all records until the data is
fully acknowledged, so if skbs reach the wrong device they can be handled
by software fallback.
Any device TLS offload handling error on the transmission side must result
in the packet being dropped. For example if a packet got out of order
due to a bug in the stack or the device, reached the device and can't
be encrypted such packet must be dropped.
RX
--
If the device encounters any problems with TLS offload on the receive
side it should pass the packet to the host's networking stack as it was
received on the wire.
For example authentication failure for any record in the segment should
result in passing the unmodified packet to the software fallback. This means
packets should not be modified "in place". Splitting segments to handle partial
decryption is not advised. In other words either all records in the packet
had been handled successfully and authenticated or the packet has to be passed
to the host's stack as it was on the wire (recovering original packet in the
driver if device provides precise error is sufficient).
The Linux networking stack does not provide a way of reporting per-packet
decryption and authentication errors, packets with errors must simply not
have the :c:member:`decrypted` mark set.
A packet should also not be handled by the TLS offload if it contains
incorrect checksums.
Performance metrics
===================
TLS offload can be characterized by the following basic metrics:
* max connection count
* connection installation rate
* connection installation latency
* total cryptographic performance
Note that each TCP connection requires a TLS session in both directions,
the performance may be reported treating each direction separately.
Max connection count
--------------------
The number of connections device can support can be exposed via
``devlink resource`` API.
Total cryptographic performance
-------------------------------
Offload performance may depend on segment and record size.
Overload of the cryptographic subsystem of the device should not have
significant performance impact on non-offloaded streams.
Statistics
==========
Following minimum set of TLS-related statistics should be reported
by the driver:
* ``rx_tls_decrypted`` - number of successfully decrypted TLS segments
* ``tx_tls_encrypted`` - number of in-order TLS segments passed to device
for encryption
* ``tx_tls_ooo`` - number of TX packets which were part of a TLS stream
but did not arrive in the expected order
* ``tx_tls_drop_no_sync_data`` - number of TX packets dropped because
they arrived out of order and associated record could not be found
(see also :ref:`pre_tls_data`)
Notable corner cases, exceptions and additional requirements
============================================================
.. _5tuple_problems:
5-tuple matching limitations
----------------------------
The device can only recognize received packets based on the 5-tuple
of the socket. Current ``ktls`` implementation will not offload sockets
routed through software interfaces such as those used for tunneling
or virtual networking. However, many packet transformations performed
by the networking stack (most notably any BPF logic) do not require
any intermediate software device, therefore a 5-tuple match may
consistently miss at the device level. In such cases the device
should still be able to perform TX offload (encryption) and should
fallback cleanly to software decryption (RX).
Out of order
------------
Introducing extra processing in NICs should not cause packets to be
transmitted or received out of order, for example pure ACK packets
should not be reordered with respect to data segments.
Ingress reorder
---------------
A device is permitted to perform packet reordering for consecutive
TCP segments (i.e. placing packets in the correct order) but any form
of additional buffering is disallowed.
Coexistence with standard networking offload features
-----------------------------------------------------
Offloaded ``ktls`` sockets should support standard TCP stack features
transparently. Enabling device TLS offload should not cause any difference
in packets as seen on the wire.
Transport layer transparency
----------------------------
The device should not modify any packet headers for the purpose
of the simplifying TLS offload.
The device should not depend on any packet headers beyond what is strictly
necessary for TLS offload.
Segment drops
-------------
Dropping packets is acceptable only in the event of catastrophic
system errors and should never be used as an error handling mechanism
in cases arising from normal operation. In other words, reliance
on TCP retransmissions to handle corner cases is not acceptable.
TLS device features
-------------------
Drivers should ignore the changes to TLS the device feature flags.
These flags will be acted upon accordingly by the core ``ktls`` code.
TLS device feature flags only control adding of new TLS connection
offloads, old connections will remain active after flags are cleared.
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.
.. _pre_tls_data:
Transmission of pre-TLS data
----------------------------
User can enqueue some already encrypted and framed records before enabling
``ktls`` on the socket. Those records have to get sent as they are. This is
perfectly easy to handle in the software case - such data will be waiting
in the TCP layer, TLS ULP won't see it. In the offloaded case when pre-queued
segment reaches transmission point it appears to be out of order (before the
expected TCP sequence number) and the stack does not have a record information
associated.
All segments without record information cannot, however, be assumed to be
pre-queued data, because a race condition exists between TCP stack queuing
a retransmission, the driver seeing the retransmission and TCP ACK arriving
for the retransmitted data.

Requirements
============
A host with a USB port. Ideally, either a UHCI (Intel) or OHCI
(Compaq and others) hardware port should work.
A host with a USB port running a Linux kernel with RIO 500 support enabled.
A Linux development kernel (2.3.x) with USB support enabled or a
backported version to linux-2.2.x. See http://www.linux-usb.org for
more information on accomplishing this.
The driver is a module called rio500, which should be automatically loaded
as you plug in your device. If that fails you can manually load it with
A Linux kernel with RIO 500 support enabled.
modprobe rio500
'lspci' which is only needed to determine the type of USB hardware
available in your machine.
Configuration
Using `lspci -v`, determine the type of USB hardware available.
If you see something like::
USB Controller: ......
Flags: .....
I/O ports at ....
Then you have a UHCI based controller.
If you see something like::
USB Controller: .....
Flags: ....
Memory at .....
Then you have a OHCI based controller.
Using `make menuconfig` or your preferred method for configuring the
kernel, select 'Support for USB', 'OHCI/UHCI' depending on your
hardware (determined from the steps above), 'USB Diamond Rio500 support', and
'Preliminary USB device filesystem'. Compile and install the modules
(you may need to execute `depmod -a` to update the module
dependencies).
Add a device for the USB rio500::
Udev should automatically create a device node as soon as plug in your device.
If that fails, you can manually add a device for the USB rio500::
mknod /dev/usb/rio500 c 180 64
Set appropriate permissions for /dev/usb/rio500 (don't forget about
group and world permissions). Both read and write permissions are
In that case, set appropriate permissions for /dev/usb/rio500 (don't forget
about group and world permissions). Both read and write permissions are
required for proper operation.
Load the appropriate modules (if compiled as modules):
OHCI::
modprobe usbcore
modprobe usb-ohci
modprobe rio500
UHCI::
modprobe usbcore
modprobe usb-uhci (or uhci)
modprobe rio500
That's it. The Rio500 Utils at: http://rio500.sourceforge.net should
be able to access the rio500.
Limits
======
You can use only a single rio500 device at a time with your computer.
