Current code fails to correctly check padding sequence for inbound
packets.
Padding sequence starts on 1 but it checks for 0.

Building the application with -O3 and -fstack-protection (default in
Ubuntu) results in the following error:
*** stack smashing detected ***: ./build/ipsec-secgw terminated
The error is caused by storing an 8B value in a 4B variable.

Add support for building the application with DEBUG=1.
This option adds the compiler stack protection flag and enables extra
output in the application.
Also remove unnecessary VPATH setup.

Rework implementation moving from function pointers approach, where each
function implements very specific functionality, to a generic function
approach.

The application only checks that an SA shoudln't be NULL through ASSERT
(only when debugging is enabled) without properly dealing with the case
of not having an SA for the processed packet.
If no SA is found, drop the packet.
Fixes: d299106e8e31 ("examples/ipsec-secgw: add IPsec sample application")

Modify the default SP config variables names to be consistent with SA.
The resulting naming convention is that variables with suffixes _out/_in
are the default for ep0 and the reverse for ep1.

Support IPSec IPv6 allowing IPv4/IPv6 traffic in IPv4 or IPv6 tunnel.
We need separate Routing (LPM) and SP (ACL) tables for IPv4 and IPv6,
but a common SA table.

For simple console code-blocks like this you can just use ::. It defaults

Current code fails to correctly check padding sequence for inbound
packets.
Padding sequence starts on 1 but it checks for 0.

Building the application with -O3 and -fstack-protection (default in
Ubuntu) results in the following error:
*** stack smashing detected ***: ./build/ipsec-secgw terminated
The error is caused by storing an 8B value in a 4B variable.

Add support for building the application with DEBUG=1.
This option adds the compiler stack protection flag and enables extra
output in the application.
Also remove unnecessary VPATH setup.

The application only checks that an SA shoudln't be NULL through ASSERT
(only when debugging is enabled) without properly dealing with the case
of not having an SA for the processed packet.
If no SA is found, drop the packet.
Fixes: d299106e8e31 ("examples/ipsec-secgw: add IPsec sample application")

Modify the default SP config variables names to be consistent with SA.
The resulting naming convention is that variables with suffixes _out/_in
are the default for ep0 and the reverse for ep1.

Support IPSec IPv6 allowing IPv4/IPv6 traffic in IPv4 or IPv6 tunnel.
We need separate Routing (LPM) and SP (ACL) tables for IPv4 and IPv6,
but a common SA table.

Compiling the Application
-------------------------
To compile the application:
-#. Go to the sample application directory:
-
- .. code-block:: console
+#. Go to the sample application directory::
export RTE_SDK=/path/to/rte_sdk
cd ${RTE_SDK}/examples/ipsec-secgw
-#. Set the target (a default target is used if not specified). For example:
+#. Set the target (a default target is used if not specified). For example::
- .. code-block:: console
export RTE_TARGET=x86_64-native-linuxapp-gcc
See the *DPDK Getting Started Guide* for possible RTE_TARGET values.
-#. Build the application:
-
- .. code-block:: console
+#. Build the application::
make
+#. [Optional] Build the application for debugging:
+ This option adds some extra flags, disables compiler optimizations and
+ is verbose::
+
+ make DEBUG=1

Running the Application

-* -P: optional, sets all ports to promiscuous mode so that packets are

accepted regardless of the packet's Ethernet MAC destination address.
Without this option, only packets with the Ethernet MAC destination address
set to the Ethernet address of the port are accepted (default is enabled).
-* -u PORTMASK: hexadecimal bitmask of unprotected ports
+* ``-u PORTMASK``: hexadecimal bitmask of unprotected ports
-* --config (port,queue,lcore)[,(port,queue,lcore)]: determines which queues
- from which ports are mapped to which cores

-* --single-sa SAIDX: use a single SA for outbound traffic, bypassing the SP
+* ``--single-sa SAIDX``: use a single SA for outbound traffic, bypassing the SP
on both Inbound and Outbound. This option is meant for debugging/performance
purposes.
-* --ep0: configure the app as Endpoint 0.

-* --ep1: configure the app as Endpoint 1.
+* ``--ep1``: configure the app as Endpoint 1.

Current code fails to correctly check padding sequence for inbound
packets.
Padding sequence starts on 1 but it checks for 0.

Building the application with -O3 and -fstack-protection (default in
Ubuntu) results in the following error:
*** stack smashing detected ***: ./build/ipsec-secgw terminated
The error is caused by storing an 8B value in a 4B variable.

Add support for building the application with DEBUG=1.
This option adds the compiler stack protection flag and enables extra
output in the application.
Also remove unnecessary VPATH setup.

Rework implementation moving from function pointers approach, where each
function implements very specific functionality, to a generic function
approach.

The application only ASSERTS that an SA is not NULL (only when debugging
is enabled) without properly dealing with the case of not having an SA
for the processed packet.
Behavior should be such as if no SA is found, drop the packet.
Fixes: d299106e8e31 ("examples/ipsec-secgw: add IPsec sample application")

Modify the default SP config variables names to be consistent with SA.
The resulting naming convention is that variables with suffixes _out/_in
are the default for ep0 and the reverse for ep1.

Support IPSec IPv6 allowing IPv4/IPv6 traffic in IPv4 or IPv6 tunnel.
We need separate Routing (LPM) and SP (ACL) tables for IPv4 and IPv6,
but a common SA table.

Hi,
This file throws an error with make doc-guides-pdf.
The image needs to be specified as "img/ipsec_endpoints.*" (now .svg) to
allow it to be converted from svg to pdf.
With this fix the build works.

This patch set mainly adds support for AES-GCM and AES-CTR.
It also updates the IV generation method for AES-CBC mode using
the forward function instead of randomly generating the IV.
v3:
- update sample app guide
- remove unused function
- improve commit messages
v2:
- Update releas notes.
- Initialize salt values, GCM/CTR key length now is 20B,
16B key and 4 LSB salt.
- Do not check SP/ACL if we have no rules.
- Add macro for cryptodev queue size
Dependencies:
examples/ipsec-secgw: add configuration file support
http://dpdk.org/dev/patchwork/patch/16004/
examples/ipsec-secgw: add sample configuration files
http://dpdk.org/dev/patchwork/patch/16003/
Sergio Gonzalez Monroy (9):
examples/ipsec-secgw: change CBC IV generation
examples/ipsec-secgw: reset crypto operation status
examples/ipsec-secgw: add AES-GCM support
examples/ipsec-secgw: enable AES-CTR mode
examples/ipsec-secgw: check sp only when setup
examples/ipsec-secgw: add cryptodev queue size macro
examples/ipsec-secgw: initialize sa salt
