This patchset adds the configuration file supported to ipsec_secgw
sample application. Two sample configuration files, ep0.cfg and ep1.cfg
are also added to show how to configure two systems back-to-back that
would forward traffic through an IPsec tunnel

This patch adds the configuration file support to ipsec_secgw
sample application. Instead of hard-coded rules, the users can
specify their own SP, SA, and routing rules in the configuration
file. An command line option "-f" is added to pass the
configuration file location to the application.
Configuration item formats:
SP rule format:
sp <ip_ver> <dir> esp <action> <priority> <src_ip> <dst_ip> \
<proto> <sport> <dport>
SA rule format:
sa <dir> <spi> <cipher_algo> <auth_algo> <mode> <src_ip> <dst_ip>
Routing rule format:
rt <ip_ver> <src_ip> <dst_ip> <port>

-Currently all configuration information is hard coded into the application.
+The following sections provide the syntax of configurations to initialize

+Configuration File Syntax
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-.. figure:: img/ipsec_endpoints.*
+As mention in the overview, the Security Policies are ACL rules.
+The application parsers the rules specified in the configuration file and
+passes them to the ACL table, and replicates them per socket in use.
- IPSec Inbound/Outbound traffic
+Following are the configuration file syntax.
-Note that the above image only displays unidirectional traffic per port
-for illustration purposes.
-The application supports bidirectional traffic on all ports,
+General rule syntax
+^^^^^^^^^^^^^^^^^^^
+The parse treats one line in the configuration file as one configuration
+item (unless the line concatenation symbol exists). Every configuration
+item shall follow the syntax of either SP, SA, or Routing rules specified
+below.
-Security Policy Initialization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The configuration parser supports the following special symbols:
-As mention in the overview, the Security Policies are ACL rules.
-The application defines two ACLs, one each of Inbound and Outbound, and
-it replicates them per socket in use.
-
-Following are the default rules which show only the relevant information,
-assuming ANY value is valid for the fields not mentioned (src ip, proto,
-src/dst ports).

-For Endpoint 1, we use the same policies in reverse, meaning the Inbound SP
-entries are set as Outbound and vice versa.
-
-
-Security Association Initialization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The SAs are kept in a array table.
-
-For Inbound, the SPI is used as index modulo the table size.
-This means that on a table for 100 SA, SPI 5 and 105 would use the same index
-and that is not currently supported.
-
-Notice that it is not an issue for Outbound traffic as we store the index and
-not the SPI in the Security Policy.
-
-All SAs configured with AES-CBC and HMAC-SHA1 share the same values for cipher
-block size and key, and authentication digest size and key.
-
-The following are the default values:

This patchset adds the configuration file supported to ipsec_secgw
sample application. Two sample configuration files, ep0.cfg and ep1.cfg
are also added to show how to configure two systems back-to-back that
would forward traffic through an IPsec tunnel
v2 changes:
- fix configuration file parsing error.
- update doc to remove whitespace tailing errors.

This patch adds the configuration file support to ipsec_secgw
sample application. Instead of hard-coded rules, the users can
specify their own SP, SA, and routing rules in the configuration
file. An command line option "-f" is added to pass the
configuration file location to the application.
Configuration item formats:
SP rule format:
sp <ip_ver> <dir> esp <action> <priority> <src_ip> <dst_ip> \
<proto> <sport> <dport>
SA rule format:
sa <dir> <spi> <cipher_algo> <auth_algo> <mode> <src_ip> <dst_ip>
Routing rule format:
rt <ip_ver> <src_ip> <dst_ip> <port>

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-.. figure:: img/ipsec_endpoints.*
+As mention in the overview, the Security Policies are ACL rules.
+The application parsers the rules specified in the configuration file and
+passes them to the ACL table, and replicates them per socket in use.
- IPSec Inbound/Outbound traffic
+Following are the configuration file syntax.
-Note that the above image only displays unidirectional traffic per port
-for illustration purposes.
-The application supports bidirectional traffic on all ports,
+General rule syntax
+^^^^^^^^^^^^^^^^^^^
+The parse treats one line in the configuration file as one configuration
+item (unless the line concatenation symbol exists). Every configuration
+item shall follow the syntax of either SP, SA, or Routing rules specified
+below.
-Security Policy Initialization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The configuration parser supports the following special symbols:
-As mention in the overview, the Security Policies are ACL rules.
-The application defines two ACLs, one each of Inbound and Outbound, and
-it replicates them per socket in use.

-For Endpoint 1, we use the same policies in reverse, meaning the Inbound SP
-entries are set as Outbound and vice versa.
-
-
-Security Association Initialization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The SAs are kept in a array table.
-
-For Inbound, the SPI is used as index modulo the table size.
-This means that on a table for 100 SA, SPI 5 and 105 would use the same index
-and that is not currently supported.
-
-Notice that it is not an issue for Outbound traffic as we store the index and
-not the SPI in the Security Policy.
-
-All SAs configured with AES-CBC and HMAC-SHA1 share the same values for cipher
-block size and key, and authentication digest size and key.
-
-The following are the default values:

There is a 32-bit compilation error:
examples/ipsec-secgw/parser.c:286:10: error:
format ‘%lu’ expects argument of type ‘long unsigned int’,
but argument 2 has type ‘size_t {aka unsigned int}’ [-Werror=format=]

This patchset adds the configuration file supported to ipsec_secgw
sample application. Two sample configuration files, ep0.cfg and ep1.cfg
are also added to show how to configure two systems back-to-back that
would forward traffic through an IPsec tunnel
v3 change:
- fix 32-bit compilation error
v2 changes:
- fix configuration file parsing error.
- update doc to remove whitespace tailing errors.

This patch adds the configuration file support to ipsec_secgw
sample application. Instead of hard-coded rules, the users can
specify their own SP, SA, and routing rules in the configuration
file. An command line option "-f" is added to pass the
configuration file location to the application.
Configuration item formats:
SP rule format:
sp <ip_ver> <dir> esp <action> <priority> <src_ip> <dst_ip> \
<proto> <sport> <dport>
SA rule format:
sa <dir> <spi> <cipher_algo> <auth_algo> <mode> <src_ip> <dst_ip>
Routing rule format:
rt <ip_ver> <src_ip> <dst_ip> <port>

Configurations
--------------
-The following sections provide some details on the default values used to
-initialize the SP, SA and Routing tables.
-Currently all configuration information is hard coded into the application.
+The following sections provide the syntax of configurations to initialize
+your SP, SA and Routing tables.
+Configurations shall be specified in the configuration file to be passed to
+the application. The file is then parsed by the application. The successful
+parsing will result in the appropriate rules being applied to the tables
+accordingly.
-The following image illustrate a few of the concepts regarding IPSec, such
-as protected/unprotected and inbound/outbound traffic, from the point of
-view of two back-to-back endpoints:
-.. _figure_ipsec_endpoints:
+Configuration File Syntax
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-.. figure:: img/ipsec_endpoints.*
+As mention in the overview, the Security Policies are ACL rules.
+The application parsers the rules specified in the configuration file and
+passes them to the ACL table, and replicates them per socket in use.
- IPSec Inbound/Outbound traffic
+Following are the configuration file syntax.
-Note that the above image only displays unidirectional traffic per port
-for illustration purposes.
-The application supports bidirectional traffic on all ports,
+General rule syntax
+^^^^^^^^^^^^^^^^^^^
+The parse treats one line in the configuration file as one configuration
+item (unless the line concatenation symbol exists). Every configuration
+item shall follow the syntax of either SP, SA, or Routing rules specified
+below.
-Security Policy Initialization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The configuration parser supports the following special symbols:
-As mention in the overview, the Security Policies are ACL rules.
-The application defines two ACLs, one each of Inbound and Outbound, and
-it replicates them per socket in use.
-
-Following are the default rules which show only the relevant information,
-assuming ANY value is valid for the fields not mentioned (src ip, proto,
-src/dst ports).

-For Endpoint 1, we use the same policies in reverse, meaning the Inbound SP
-entries are set as Outbound and vice versa.
-
-
-Security Association Initialization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The SAs are kept in a array table.
-
-For Inbound, the SPI is used as index modulo the table size.
-This means that on a table for 100 SA, SPI 5 and 105 would use the same index
-and that is not currently supported.
-
-Notice that it is not an issue for Outbound traffic as we store the index and
-not the SPI in the Security Policy.
-
-All SAs configured with AES-CBC and HMAC-SHA1 share the same values for cipher
-block size and key, and authentication digest size and key.
-

I think we should be able to set the key also on config file for both
cipher and auth.
Then we can check that the key size is the expected by the chosen
cipher/auth algo.
I think we should also create and set the xforms dynamically instead of
static as
they currently are (sa_add_rules function).

This patchset adds the configuration file supported to ipsec_secgw
sample application. Two sample configuration files, ep0.cfg and ep1.cfg
are also added to show how to configure two systems back-to-back that
would forward traffic through an IPsec tunnel
v4 change:
- rebase the patchset on top of
"examples/ipsec-secgw: fix GCC 4.5.x build error"
(http://dpdk.org/dev/patchwork/patch/14895/)
- add cipher_key and auth_key configuration options to SA rules
- updated documentation for the new options
v3 change:
- fix 32-bit compilation error
v2 changes:
- fix configuration file parsing error.
- update doc to remove whitespace tailing errors.

This patch adds the configuration file support to ipsec_secgw
sample application. Instead of hard-coded rules, the users can
specify their own SP, SA, and routing rules in the configuration
file. An command line option "-f" is added to pass the
configuration file location to the application.
Configuration item formats:
SP rule format:
sp <ip_ver> <dir> esp <action> <priority> <src_ip> <dst_ip> \
<proto> <sport> <dport>
SA rule format:
sa <dir> <spi> <cipher_algo> <cipher_key> <auth_algo> <auth_key> \
<mode> <src_ip> <dst_ip>
Routing rule format:

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-.. figure:: img/ipsec_endpoints.*
+As mention in the overview, the Security Policies are ACL rules.
+The application parsers the rules specified in the configuration file and
+passes them to the ACL table, and replicates them per socket in use.

+Following are the configuration file syntax.
-Note that the above image only displays unidirectional traffic per port

-The application supports bidirectional traffic on all ports,
+General rule syntax
+^^^^^^^^^^^^^^^^^^^
+The parse treats one line in the configuration file as one configuration
+item (unless the line concatenation symbol exists). Every configuration
+item shall follow the syntax of either SP, SA, or Routing rules specified
+below.
-Security Policy Initialization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The configuration parser supports the following special symbols:
-As mention in the overview, the Security Policies are ACL rules.
-The application defines two ACLs, one each of Inbound and Outbound, and

-For Endpoint 1, we use the same policies in reverse, meaning the Inbound SP
-entries are set as Outbound and vice versa.
-
-
-Security Association Initialization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The SAs are kept in a array table.
-
-For Inbound, the SPI is used as index modulo the table size.
-This means that on a table for 100 SA, SPI 5 and 105 would use the same index
-and that is not currently supported.
-
-Notice that it is not an issue for Outbound traffic as we store the index and
-not the SPI in the Security Policy.
-
-All SAs configured with AES-CBC and HMAC-SHA1 share the same values for cipher
-block size and key, and authentication digest size and key.

+
+The successfully parsed SA rules will be stored in an array table.
+
+All SAs configured with AES-CBC and HMAC-SHA1 share the same values for
+cipher block size and key, and authentication digest size and key.
+
+The SA rule syntax is shown as follows:
+

+ * Optional: No, must followed by <cipher_algo> option
+
+ * Syntax: Hexadecimal bytes (0x0-0xFF) concatenate by colon symbol ':'.
+ The number of bytes should be as same as the specified cipher algorithm
+ key size.
+
+ For example: *cipher_key A1:B2:C3:D4:A1:B2:C3:D4:A1:B2:C3:D4:
+ A1:B2:C3:D4*

This patchset adds the configuration file supported to ipsec_secgw
sample application. Two sample configuration files, ep0.cfg and ep1.cfg
are also added to show how to configure two systems back-to-back that
would forward traffic through an IPsec tunnel
v5 change:
- fix missed SA cipher key length checking parsing error
- fix SA ip address printing
v4 change:
- rebase the patchset on top of
"examples/ipsec-secgw: fix GCC 4.5.x build error"
(http://dpdk.org/dev/patchwork/patch/14895/)
- add cipher_key and auth_key configuration options to SA rules
- updated documentation for the new options
v3 change:
- fix 32-bit compilation error
v2 changes:
- fix configuration file parsing error.
- update doc to remove whitespace tailing errors.

This patch adds the configuration file support to ipsec_secgw
sample application. Instead of hard-coded rules, the users can
specify their own SP, SA, and routing rules in the configuration
file. An command line option "-f" is added to pass the
configuration file location to the application.
Configuration item formats:
SP rule format:
sp <ip_ver> <dir> esp <action> <priority> <src_ip> <dst_ip> \
<proto> <sport> <dport>
SA rule format:
sa <dir> <spi> <cipher_algo> <cipher_key> <auth_algo> <auth_key> \
<mode> <src_ip> <dst_ip>
Routing rule format:
rt <ip_ver> <src_ip> <dst_ip> <port>

Configurations
--------------
-The following sections provide some details on the default values used to
-initialize the SP, SA and Routing tables.
-Currently all configuration information is hard coded into the application.
+The following sections provide the syntax of configurations to initialize
+your SP, SA and Routing tables.
+Configurations shall be specified in the configuration file to be passed to
+the application. The file is then parsed by the application. The successful
+parsing will result in the appropriate rules being applied to the tables
+accordingly.
-The following image illustrate a few of the concepts regarding IPSec, such
-as protected/unprotected and inbound/outbound traffic, from the point of
-view of two back-to-back endpoints:
-.. _figure_ipsec_endpoints:
+Configuration File Syntax
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-.. figure:: img/ipsec_endpoints.*
+As mention in the overview, the Security Policies are ACL rules.
+The application parsers the rules specified in the configuration file and
+passes them to the ACL table, and replicates them per socket in use.
- IPSec Inbound/Outbound traffic
+Following are the configuration file syntax.
-Note that the above image only displays unidirectional traffic per port
-for illustration purposes.
-The application supports bidirectional traffic on all ports,
+General rule syntax
+^^^^^^^^^^^^^^^^^^^
+The parse treats one line in the configuration file as one configuration
+item (unless the line concatenation symbol exists). Every configuration
+item shall follow the syntax of either SP, SA, or Routing rules specified
+below.
-Security Policy Initialization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The configuration parser supports the following special symbols:
-As mention in the overview, the Security Policies are ACL rules.
-The application defines two ACLs, one each of Inbound and Outbound, and
-it replicates them per socket in use.
-
-Following are the default rules which show only the relevant information,
-assuming ANY value is valid for the fields not mentioned (src ip, proto,
-src/dst ports).

-For Endpoint 1, we use the same policies in reverse, meaning the Inbound SP
-entries are set as Outbound and vice versa.
-
-
-Security Association Initialization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The SAs are kept in a array table.
-
-For Inbound, the SPI is used as index modulo the table size.
-This means that on a table for 100 SA, SPI 5 and 105 would use the same index
-and that is not currently supported.
-
-Notice that it is not an issue for Outbound traffic as we store the index and
-not the SPI in the Security Policy.
-
-All SAs configured with AES-CBC and HMAC-SHA1 share the same values for cipher
-block size and key, and authentication digest size and key.

+SA rule syntax
+^^^^^^^^^^^^^^
+
+The successfully parsed SA rules will be stored in an array table.
+
+All SAs configured with AES-CBC and HMAC-SHA1 share the same values for
+cipher block size and key, and authentication digest size and key.
+
+The SA rule syntax is shown as follows:
+
+.. code-block:: console
+
+ sa <dir> <spi> <cipher_algo> <cipher_key> <auth_algo> <auth_key>
+ <mode> <src_ip> <dst_ip>
+
+where each options means:
+
+``<dir>``
+
+ * The traffic direction
+
+ * Optional: No
+
+ * Available options:
+
+ * *in*: inbound traffic
+ * *out*: outbound traffic
+
+``<spi>``
+
+ * The SPI number
+
+ * Optional: No
+
+ * Syntax: unsigned integer number
+
+``<cipher_algo>``
+
+ * Cipher algorithm
+
+ * Optional: No
+
+ * Available options:
+
+ * *null*: NULL algorithm
+ * *aes-128-cbc*: AES-CBC 128-bit algorithm
+
+ * Syntax: *cipher_algo <your algorithm>*
+
+``<cipher_key>``
+
+ * Cipher key, NOT available when 'null' algorithm is used
+
+ * Optional: No, must followed by <cipher_algo> option
+
+ * Syntax: Hexadecimal bytes (0x0-0xFF) concatenate by colon symbol ':'.
+ The number of bytes should be as same as the specified cipher algorithm
+ key size.
+
+ For example: *cipher_key A1:B2:C3:D4:A1:B2:C3:D4:A1:B2:C3:D4:
+ A1:B2:C3:D4*
+
+``<auth_algo>``
+
+ * Authentication algorithm
+
+ * Optional: No
+
+ * Available options:
+
+ * *null*: NULL algorithm
+ * *sha1-hmac*: HMAC SHA1 algorithm
+
+``<auth_key>``
+
+ * Authentication key, NOT available when 'null' algorithm is used
+
+ * Optional: No, must followed by <auth_algo> option
+
+ * Syntax: Hexadecimal bytes (0x0-0xFF) concatenate by colon symbol ':'.
+ The number of bytes should be as same as the specified authentication
+ algorithm key size.
+
+ For example: *auth_key A1:B2:C3:D4:A1:B2:C3:D4:A1:B2:C3:D4:A1:B2:C3:D4:
+ A1:B2:C3:D4*
+
+``<mode>``
+
+ * The operation mode
+
+ * Optional: No
+
+ * Available options:
+
+ * *ipv4-tunnel*: Tunnel mode for IPv4 packets
+ * *ipv6-tunnel*: Tunnel mode for IPv6 packets
+ * *transport*: transport mode
+
+ * Syntax: mode XXX
+
+``<src_ip>``
+
+ * The source IP address. This option is not available when
+ transport mode is used
+
+ * Optional: Yes, default address 0.0.0.0 will be used
+
+ * Syntax:
+
+ * *src X.X.X.X* for IPv4
+ * *src XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX* for IPv6
+
+``<dst_ip>``
+
+ * The destination IP address. This option is not available when
+ transport mode is used
+
+ * Optional: Yes, default address 0.0.0.0 will be used
+
+ * Syntax:
+
+ * *dst X.X.X.X* for IPv4
+ * *dst XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX* for IPv6
+
+Example SA rules:
+
+.. code-block:: console
+
+ sa out 5 cipher_algo null auth_algo null mode ipv4-tunnel \
+ src 172.16.1.5 dst 172.16.2.5
+
+ sa out 25 cipher_algo aes-128-cbc \
+ cipher_key c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3 \
+ auth_algo sha1-hmac \
+ auth_key c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3 \
+ mode ipv6-tunnel \
+ src 1111:1111:1111:1111:1111:1111:1111:5555 \
+ dst 2222:2222:2222:2222:2222:2222:2222:5555
+
+
+Routing rule syntax
+^^^^^^^^^^^^^^^^^^^
+
+The Routing rule syntax is shown as follows:
+
+.. code-block:: console
+
+ rt <ip_ver> <src_ip> <dst_ip> <port>
+
+
+where each options means:
+
+``<ip_ver>``
+
+ * IP protocol version
+
+ * Optional: No
+
+ * Available options:
+
+ * *ipv4*: IP protocol version 4
+ * *ipv6*: IP protocol version 6
+
+``<src_ip>``
+
+ * The source IP address and mask
+
+ * Optional: Yes, default address 0.0.0.0 and mask of 0 will be used
+
+ * Syntax:
+
+ * *src X.X.X.X/Y* for IPv4
+ * *src XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX/Y* for IPv6
+
+``<dst_ip>``
+
+ * The destination IP address and mask
+
+ * Optional: Yes, default address 0.0.0.0 and mask of 0 will be used
+
+ * Syntax:
+
+ * *dst X.X.X.X/Y* for IPv4

+
+``<port>``
+
+ * The traffic output port id
+
+ * Optional: yes, default output port 0 will be used
+
+ * Syntax: *port X*
+
+Example SP rules:
+
+.. code-block:: console
+
+ rt ipv4 dst 172.16.1.5/32 port 0
+
+ rt ipv6 dst 1111:1111:1111:1111:1111:1111:1111:5555/116 port 0

This patchset adds the configuration file supported to ipsec_secgw
sample application. Two sample configuration files, ep0.cfg and ep1.cfg
are also added to show how to configure two systems back-to-back that
would forward traffic through an IPsec tunnel
v6 change:
- fix SA digest key always 0 error
v5 change:
- fix missed SA key length checking parsing error
- fix SA ip address printing
v4 change:
- rebase the patchset on top of
"examples/ipsec-secgw: fix GCC 4.5.x build error"
(http://dpdk.org/dev/patchwork/patch/14895/)
- add cipher_key and auth_key configuration options to SA rules
- updated documentation for the new options
v3 change:
- fix 32-bit compilation error

This patch adds the configuration file support to ipsec_secgw
sample application. Instead of hard-coded rules, the users can
specify their own SP, SA, and routing rules in the configuration
file. An command line option "-f" is added to pass the
configuration file location to the application.
Configuration item formats:
SP rule format:
sp <ip_ver> <dir> esp <action> <priority> <src_ip> <dst_ip> \
<proto> <sport> <dport>
SA rule format:
sa <dir> <spi> <cipher_algo> <cipher_key> <auth_algo> <auth_key> \
<mode> <src_ip> <dst_ip>
Routing rule format:
rt <ip_ver> <src_ip> <dst_ip> <port>

Configurations
--------------
-The following sections provide some details on the default values used to

-Currently all configuration information is hard coded into the application.
+The following sections provide the syntax of configurations to initialize
+your SP, SA and Routing tables.
+Configurations shall be specified in the configuration file to be passed to

+parsing will result in the appropriate rules being applied to the tables
+accordingly.

-.. _figure_ipsec_endpoints:
+Configuration File Syntax
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-.. figure:: img/ipsec_endpoints.*
+As mention in the overview, the Security Policies are ACL rules.
+The application parsers the rules specified in the configuration file and
+passes them to the ACL table, and replicates them per socket in use.
- IPSec Inbound/Outbound traffic
+Following are the configuration file syntax.
-Note that the above image only displays unidirectional traffic per port
-for illustration purposes.
-The application supports bidirectional traffic on all ports,
+General rule syntax
+^^^^^^^^^^^^^^^^^^^
+The parse treats one line in the configuration file as one configuration
+item (unless the line concatenation symbol exists). Every configuration
+item shall follow the syntax of either SP, SA, or Routing rules specified
+below.
-Security Policy Initialization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The configuration parser supports the following special symbols:
-As mention in the overview, the Security Policies are ACL rules.
-The application defines two ACLs, one each of Inbound and Outbound, and
-it replicates them per socket in use.
-
-Following are the default rules which show only the relevant information,
-assuming ANY value is valid for the fields not mentioned (src ip, proto,
-src/dst ports).

-For Endpoint 1, we use the same policies in reverse, meaning the Inbound SP
-entries are set as Outbound and vice versa.
-
-
-Security Association Initialization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The SAs are kept in a array table.
-
-For Inbound, the SPI is used as index modulo the table size.
-This means that on a table for 100 SA, SPI 5 and 105 would use the same index
-and that is not currently supported.
-
-Notice that it is not an issue for Outbound traffic as we store the index and
-not the SPI in the Security Policy.
-
-All SAs configured with AES-CBC and HMAC-SHA1 share the same values for cipher
-block size and key, and authentication digest size and key.
-
-The following are the default values:

+SA rule syntax
+^^^^^^^^^^^^^^
+
+The successfully parsed SA rules will be stored in an array table.
+
+All SAs configured with AES-CBC and HMAC-SHA1 share the same values for
+cipher block size and key, and authentication digest size and key.
+
+The SA rule syntax is shown as follows:
+

+ * Optional: No, must followed by <cipher_algo> option
+
+ * Syntax: Hexadecimal bytes (0x0-0xFF) concatenate by colon symbol ':'.
+ The number of bytes should be as same as the specified cipher algorithm
+ key size.
+
+ For example: *cipher_key A1:B2:C3:D4:A1:B2:C3:D4:A1:B2:C3:D4:
+ A1:B2:C3:D4*

This patchset adds the configuration file supported to ipsec_secgw
sample application. Two sample configuration files, ep0.cfg and ep1.cfg
are also added to show how to configure two systems back-to-back that
would forward traffic through an IPsec tunnel
v7 change:
- updated release note
v6 change:
- fix SA digest key always 0 error
v5 change:
- fix missed SA key length checking parsing error
- fix SA ip address printing
v4 change:
- rebase the patchset on top of
"examples/ipsec-secgw: fix GCC 4.5.x build error"
(http://dpdk.org/dev/patchwork/patch/14895/)
- add cipher_key and auth_key configuration options to SA rules
- updated documentation for the new options
v3 change:
- fix 32-bit compilation error
v2 changes:
- fix configuration file parsing error.
- update doc to remove whitespace tailing errors.

This patch adds the configuration file support to ipsec_secgw
sample application. Instead of hard-coded rules, the users can
specify their own SP, SA, and routing rules in the configuration
file. An command line option "-f" is added to pass the
configuration file location to the application.
Configuration item formats:
SP rule format:
sp <ip_ver> <dir> esp <action> <priority> <src_ip> <dst_ip> \
<proto> <sport> <dport>
SA rule format:
sa <dir> <spi> <cipher_algo> <cipher_key> <auth_algo> <auth_key> \
<mode> <src_ip> <dst_ip>
Routing rule format:
rt <ip_ver> <src_ip> <dst_ip> <port>

Configurations
--------------
-The following sections provide some details on the default values used to
-initialize the SP, SA and Routing tables.
-Currently all configuration information is hard coded into the application.
+The following sections provide the syntax of configurations to initialize
+your SP, SA and Routing tables.
+Configurations shall be specified in the configuration file to be passed to
+the application. The file is then parsed by the application. The successful
+parsing will result in the appropriate rules being applied to the tables
+accordingly.
-The following image illustrate a few of the concepts regarding IPSec, such
-as protected/unprotected and inbound/outbound traffic, from the point of
-view of two back-to-back endpoints:
-.. _figure_ipsec_endpoints:
+Configuration File Syntax
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-.. figure:: img/ipsec_endpoints.*
+As mention in the overview, the Security Policies are ACL rules.
+The application parsers the rules specified in the configuration file and
+passes them to the ACL table, and replicates them per socket in use.
- IPSec Inbound/Outbound traffic
+Following are the configuration file syntax.
-Note that the above image only displays unidirectional traffic per port
-for illustration purposes.
-The application supports bidirectional traffic on all ports,
+General rule syntax
+^^^^^^^^^^^^^^^^^^^
+The parse treats one line in the configuration file as one configuration
+item (unless the line concatenation symbol exists). Every configuration
+item shall follow the syntax of either SP, SA, or Routing rules specified
+below.
-Security Policy Initialization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The configuration parser supports the following special symbols:
-As mention in the overview, the Security Policies are ACL rules.
-The application defines two ACLs, one each of Inbound and Outbound, and
-it replicates them per socket in use.
-
-Following are the default rules which show only the relevant information,
-assuming ANY value is valid for the fields not mentioned (src ip, proto,
-src/dst ports).

-For Endpoint 1, we use the same policies in reverse, meaning the Inbound SP
-entries are set as Outbound and vice versa.
-
-
-Security Association Initialization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The SAs are kept in a array table.
-
-For Inbound, the SPI is used as index modulo the table size.
-This means that on a table for 100 SA, SPI 5 and 105 would use the same index
-and that is not currently supported.
-
-Notice that it is not an issue for Outbound traffic as we store the index and
-not the SPI in the Security Policy.
-
-All SAs configured with AES-CBC and HMAC-SHA1 share the same values for cipher
-block size and key, and authentication digest size and key.

+SA rule syntax
+^^^^^^^^^^^^^^
+
+The successfully parsed SA rules will be stored in an array table.
+
+All SAs configured with AES-CBC and HMAC-SHA1 share the same values for
+cipher block size and key, and authentication digest size and key.
+
+The SA rule syntax is shown as follows:
+
+.. code-block:: console
+
+ sa <dir> <spi> <cipher_algo> <cipher_key> <auth_algo> <auth_key>
+ <mode> <src_ip> <dst_ip>
+
+where each options means:
+
+``<dir>``
+
+ * The traffic direction
+
+ * Optional: No
+
+ * Available options:
+
+ * *in*: inbound traffic
+ * *out*: outbound traffic
+
+``<spi>``
+
+ * The SPI number
+
+ * Optional: No
+
+ * Syntax: unsigned integer number
+
+``<cipher_algo>``
+
+ * Cipher algorithm
+
+ * Optional: No
+
+ * Available options:
+
+ * *null*: NULL algorithm
+ * *aes-128-cbc*: AES-CBC 128-bit algorithm
+
+ * Syntax: *cipher_algo <your algorithm>*
+
+``<cipher_key>``
+
+ * Cipher key, NOT available when 'null' algorithm is used
+
+ * Optional: No, must followed by <cipher_algo> option
+
+ * Syntax: Hexadecimal bytes (0x0-0xFF) concatenate by colon symbol ':'.
+ The number of bytes should be as same as the specified cipher algorithm
+ key size.
+
+ For example: *cipher_key A1:B2:C3:D4:A1:B2:C3:D4:A1:B2:C3:D4:
+ A1:B2:C3:D4*
+
+``<auth_algo>``
+
+ * Authentication algorithm
+
+ * Optional: No
+
+ * Available options:
+
+ * *null*: NULL algorithm
+ * *sha1-hmac*: HMAC SHA1 algorithm
+
+``<auth_key>``
+
+ * Authentication key, NOT available when 'null' algorithm is used
+
+ * Optional: No, must followed by <auth_algo> option
+
+ * Syntax: Hexadecimal bytes (0x0-0xFF) concatenate by colon symbol ':'.
+ The number of bytes should be as same as the specified authentication
+ algorithm key size.
+
+ For example: *auth_key A1:B2:C3:D4:A1:B2:C3:D4:A1:B2:C3:D4:A1:B2:C3:D4:
+ A1:B2:C3:D4*
+
+``<mode>``
+
+ * The operation mode
+
+ * Optional: No
+
+ * Available options:
+
+ * *ipv4-tunnel*: Tunnel mode for IPv4 packets
+ * *ipv6-tunnel*: Tunnel mode for IPv6 packets
+ * *transport*: transport mode
+
+ * Syntax: mode XXX
+
+``<src_ip>``
+
+ * The source IP address. This option is not available when
+ transport mode is used
+
+ * Optional: Yes, default address 0.0.0.0 will be used
+
+ * Syntax:
+
+ * *src X.X.X.X* for IPv4
+ * *src XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX* for IPv6
+
+``<dst_ip>``
+
+ * The destination IP address. This option is not available when
+ transport mode is used
+
+ * Optional: Yes, default address 0.0.0.0 will be used
+
+ * Syntax:
+
+ * *dst X.X.X.X* for IPv4
+ * *dst XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX* for IPv6
+
+Example SA rules:
+
+.. code-block:: console
+
+ sa out 5 cipher_algo null auth_algo null mode ipv4-tunnel \
+ src 172.16.1.5 dst 172.16.2.5
+
+ sa out 25 cipher_algo aes-128-cbc \
+ cipher_key c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3 \
+ auth_algo sha1-hmac \
+ auth_key c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3:c3 \
+ mode ipv6-tunnel \
+ src 1111:1111:1111:1111:1111:1111:1111:5555 \
+ dst 2222:2222:2222:2222:2222:2222:2222:5555
+
+
+Routing rule syntax
+^^^^^^^^^^^^^^^^^^^
+
+The Routing rule syntax is shown as follows:
+
+.. code-block:: console
+
+ rt <ip_ver> <src_ip> <dst_ip> <port>
+
+
+where each options means:
+
+``<ip_ver>``
+
+ * IP protocol version
+
+ * Optional: No
+
+ * Available options:
+
+ * *ipv4*: IP protocol version 4
+ * *ipv6*: IP protocol version 6
+
+``<src_ip>``
+
+ * The source IP address and mask
+
+ * Optional: Yes, default address 0.0.0.0 and mask of 0 will be used
+
+ * Syntax:
+
+ * *src X.X.X.X/Y* for IPv4
+ * *src XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX/Y* for IPv6
+
+``<dst_ip>``
+
+ * The destination IP address and mask
+
+ * Optional: Yes, default address 0.0.0.0 and mask of 0 will be used
+
+ * Syntax:
+
+ * *dst X.X.X.X/Y* for IPv4
+ * *dst XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX/Y* for IPv6
+
+``<port>``
+
+ * The traffic output port id
+
+ * Optional: yes, default output port 0 will be used
+
+ * Syntax: *port X*
+
+Example SP rules:
+
+.. code-block:: console
+
+ rt ipv4 dst 172.16.1.5/32 port 0
+
+ rt ipv6 dst 1111:1111:1111:1111:1111:1111:1111:5555/116 port 0

This patch adds the configuration file support to ipsec_secgw
sample application. Instead of hard-coded rules, the users can
specify their own SP, SA, and routing rules in the configuration
file. An command line option "-f" is added to pass the
configuration file location to the application.
Configuration item formats:
SP rule format:
sp <ip_ver> <dir> esp <action> <priority> <src_ip> <dst_ip> \
<proto> <sport> <dport>
SA rule format:
sa <dir> <spi> <cipher_algo> <cipher_key> <auth_algo> <auth_key> \
<mode> <src_ip> <dst_ip>
Routing rule format:
rt <ip_ver> <src_ip> <dst_ip> <port>

+Configuration File Syntax
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-.. figure:: img/ipsec_endpoints.*
+As mention in the overview, the Security Policies are ACL rules.
+The application parsers the rules specified in the configuration file and
+passes them to the ACL table, and replicates them per socket in use.
- IPSec Inbound/Outbound traffic
+Following are the configuration file syntax.
-Note that the above image only displays unidirectional traffic per port
-for illustration purposes.
-The application supports bidirectional traffic on all ports,
+General rule syntax
+^^^^^^^^^^^^^^^^^^^
+The parse treats one line in the configuration file as one configuration
+item (unless the line concatenation symbol exists). Every configuration
+item shall follow the syntax of either SP, SA, or Routing rules specified
+below.
-Security Policy Initialization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+The configuration parser supports the following special symbols:
-As mention in the overview, the Security Policies are ACL rules.
-The application defines two ACLs, one each of Inbound and Outbound, and
-it replicates them per socket in use.
-
-Following are the default rules which show only the relevant information,
-assuming ANY value is valid for the fields not mentioned (src ip, proto,
-src/dst ports).

-For Endpoint 1, we use the same policies in reverse, meaning the Inbound SP
-entries are set as Outbound and vice versa.
-
-
-Security Association Initialization
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The SAs are kept in a array table.
-
-For Inbound, the SPI is used as index modulo the table size.
-This means that on a table for 100 SA, SPI 5 and 105 would use the same index
-and that is not currently supported.
-
-Notice that it is not an issue for Outbound traffic as we store the index and
-not the SPI in the Security Policy.
-
-All SAs configured with AES-CBC and HMAC-SHA1 share the same values for cipher
-block size and key, and authentication digest size and key.
-
-The following are the default values:

+SA rule syntax
+^^^^^^^^^^^^^^
+
+The successfully parsed SA rules will be stored in an array table.
+
+All SAs configured with AES-CBC and HMAC-SHA1 share the same values for
+cipher block size and key, and authentication digest size and key.
+
+The SA rule syntax is shown as follows:
+
+.. code-block:: console

+
+ * Optional: No, must followed by <cipher_algo> option
+
+ * Syntax: Hexadecimal bytes (0x0-0xFF) concatenate by colon symbol ':'.
+ The number of bytes should be as same as the specified cipher algorithm
+ key size.
+
+ For example: *cipher_key A1:B2:C3:D4:A1:B2:C3:D4:A1:B2:C3:D4:
+ A1:B2:C3:D4*
+
+``<auth_algo>``

- Apply patch: Pass
- Compile: Pass
- OS: 3.17.4-301.fc21.x86_64
- GCC: 4.9.2
Test Case - Pass
- Launch ipsec-gateway with "-f" parameter and ep0.cfg, check the default configuration file work.
- Modified Algorithm in config file and launch ipsec-gateway and check the new algorithm effected
- Modified the key and check the key effected.
- Modified the iv and check the iv effected
- Modified the router rule and check the the rule effected
But for negative test,
If input incorrect key and iv, the application will PANIC in parse_cfg_file()
For instance, change the line 70 in ep0.cfg, add 1 more <space> at the end of line, like "a0:a0:a0: \"
The application will Abort (core dump). Expected it should report error and exit safe.
