       pf_key - Security association database interface

       #include <sys/types.h>
       #include <sys/socket.h>
       #include <net/pfkeyv2.h>

       int socket(PF_KEY,SOCK_RAW,PF_KEY_V2);

       Keying  information  for IPsec security services is maintained in secu‐
       rity association databases (SADBs). The security associations (SAs) are
       used to protect both inbound and outbound packets.

       A  user process (or possibly multiple co-operating processes) maintains
       SADBs by sending messages over a special kind of socket. This is analo‐
       gous  to the method described in route(4P). Only a superuser may access
       an SADB.

       Oracle Solaris applications that use  PF_KEY  include  ipseckey(8)  and

       The  operating system can spontaneously send pf_key messages to listen‐
       ing processes, such as a request for a new SA for an outbound  datagram
       or to report the expiration of an existing SA.

       One  opens  the  channel for passing SADB control messages by using the
       socket call shown in the Synopsis section  above.  More  than  one  key
       socket can be open per system.

       Messages  are  formed  by a small base header, followed by zero or more
       extension messages, some of which  require  additional  data  following
       them.  The  base message and all extensions must be eight-byte aligned.
       An example message is the GET message, which requires the base  header,
       the SA extension, and the ADDRESS_DST extension.

       Messages include:

         #define    SADB_GETSPI  /* Get a new SPI value from the system. */
         #define    SADB_UPDATE     /* Update an SA. */
         #define    SADB_ADD        /* Add a fully-formed SA. */

   Message Use and Behavior
       Each message has a behavior. A behavior is defined as where the initial
       message travels, for example,  user  to  kernel,  and  what  subsequent
       actions  are  expected  to  take place. Contents of messages are illus‐
       trated as:


       The SA extension is sometimes used only for its SPI field. If all other
       fields must be ignored, this is represented by SA(*).

       The lifetime extensions are represented with one to three letters after
       the word lifetime, representing (H)ARD, (S)OFT, and (C)URRENT.

       The address extensions are represented with one to three letters  after
       the word address, representing (S)RC, (D)ST, (Nl)NAT-T local, (Nr)NAT-T
       remote, (Is)Inner source, and (Id)Inner destination.

       Source and destination address extensions reflect  outer-header  selec‐
       tors  for  an IPsec SA. An SA is inbound or outbound depending on which
       of the source or destination address is local to the node. Inner-source
       and  inner-destination  selectors  represent inner-header selectors for
       Tunnel Mode SAs. A Tunnel Mode SA must  have  either  IPPROTO_ENCAP  or
       IPPROTO_IPV6  in its outer-headers as protocol selector, in addition to
       filled-in Inner-address extensions.

       NAT-T local and NAT-T remote addresses store  local  and  remote  ports
       used  for  ESP-in-UDP  encapsulation.  A  non-zero  local NAT-T address
       extension represents the local node's external IP address if it is  not
       equivalent  to  the SA's local address. A non-zero remote NAT-T address
       represents a peer's behind-a-NAT address if it is not equivalent to the
       SA's remote address. An SA with NAT-T extensions protects-and-transmits
       outbound traffic. Processing of inbound NAT-T traffic  requires  a  UDP
       socket  bound  to  the  appropriate  local  port  and  it must have the
       UDP_NAT_T_ENDPOINT (see udp(4P)) socket option enabled.

       Note that when an error occurs, only the base header is  sent.  In  the
       event of an error, an extended diagnostic can be set (see DIAGNOSTICS).
       Typical errors include:

       EINVAL     Various message improprieties, including SPI ranges that are
                  malformed,  weak keys, and others. If EINVAL is returned, an
                  application should look at the  sadb_x_msg_diagnostic  field
                  of  the sadb_msg structure. It contains one of many possible
                  causes for EINVAL. See net/pfkeyv2.h for values, all of  the
                  form SADB_X_DIAGNOSTIC_.

       ENOMEM     Needed memory was not available.

       ENSGSIZ    Message exceeds the maximum length allowed.

       EEXIST     SA  (that  is  being  added  or created with GETSPI) already

       ESRCH      SA could not be found.

       The following are examples of message use and behavior:

       Send a SADB_GETSPI message from a user process to the kernel.

         <base, address, SPI range>

       The kernel returns the SADB_GETSPI message to all listening processes.

         <base, SA(*), address (SD)>

       Send a SADB_UPDATE message from a user process to the kernel.

         <base, SA, (lifetime(HS),) address(SD), (address(Is,Id),
          address(Nl,Nr),key (AE), (identity(SD),) (sensitivity, outer sensitivity)>

       The kernel returns the SADB_UPDATE message to all listening processes.

         <base, SA(*), address (SD), (pair)>

       Adding a sadb_x_pair extension to an SADB_UPDATE  or  SADB_ADD  message
       updates the security association pair linkage with the SPI of the secu‐
       rity association contained in that extension.  The  resulting  security
       association  pair  can  be  updated  or  as  a  single entity using the
       SADB_X_UPDATEPAIR or SADB_X_DELPAIR message types.

       Send a SADB_ADD message from a user process to the kernel.

         <base, SA, (lifetime(HS),) address(SD), (address(Is,Id),)
           (address(Nl,Nr),) key(AE), (identity(SD),) (sensitivity, outer sensitivity) (pair)>

       The kernel returns the SADB_ADD message to all listening processes.

         <base, SA, (lifetime(HS),) address (SD), (address(Is,Id),)
            (address(Nl,Nr),) (identity (SD),) (sensitivity, outer sensitivity)>

       Send a SADB_X_UPDATEPAIR message from a user  process  to  the  kernel.
       This  message  type is used to update the lifetime values of a security
       association and the lifetime values of the security association  it  is
       paired with.

         <base, SA, lifetime(HS), address(SD)>

       Send  a  SADB_DELETE  message  from  a  user process to the kernel. The
       SADB_X_DELPAIR message type requests deletion of the security  associa‐
       tion and the security association it is paired with.

         <base, SA (*), address (SD)>

       The kernel returns the SADB_DELETE message to all listening processes.

         <base, SA (*), address (SD)>

       Send a SADB_GET message from a user process to the kernel.

         <base, SA (*), address (SD)>

       The  kernel  returns  the  SADB_GET message to the socket that sent the
       SADB_GET message.

         <base, SA , (lifetime (HSC),) address SD), (address (P),) key (AE),
            (identity (SD),) (sensitivity, outer sensitivity)>

       The kernel sends a SADB_ACQUIRE message  to  registered  sockets.  Note
       that  any  GETSPI,  ADD, or UPDATE calls in reaction to an ACQUIRE must
       fill in the sadb_msg_seq of those messages with the one in the  ACQUIRE
       message.  The  address (SD) extensions must have the port fields filled
       in with the port numbers of the session requiring keys if appropriate.

         <base, address (SD), (address(Is,Id)), (identity(SD),)
              (sensitivity) proposal>

       Extended ACQUIRE has a slightly different format.  The  sadb_msg_satype
       field  is  0,  and the extension contains the desired combination(s) of
       security protocols.

         <base, address (SD), (address(Is,Id)), (identity(SD),)
                                (sensitivity,) eprop>

       If key management fails, send an SADB_ACQUIRE to indicate failure.


       For inbound Key Management processing, a Key Management application can
       wish  to consult the kernel for its policy. The application should send
       to the kernel:

         <base, address (SD), (address(Is,Id))>

       The kernel returns a message similar  to  a  kernel-generated  extended

         <base, address (SD), (address(Is,Id)), (identity(SD),)
                                (sensitivity,) eprop>

       Send a SADB_REGISTER message from a user process to the kernel.


       The  kernel  returns  the  SADB_REGISTER message to registered sockets,
       with algorithm types supported by the kernel  being  indicated  in  the
       supported  algorithms  field.  Note  that this message can arrive asyn‐
       chronously due to an algorithm being loaded or unloaded into a  dynami‐
       cally linked kernel.

         <base, supported>

       There  is  also  the  extended  REGISTER,  which allows this process to
       receive extended ACQUIREs.

         <base, ereg>

       Which returns a series of SADB_REGISTER replies (one for each  security
       protocol registered) from the kernel.

       The  kernel  sends a SADB_EXPIRE message to all listeners when the soft
       limit of a security association has been expired.

         <base, SA, lifetime (C and one of HS), address (SD)>

       Send a SADB_FLUSH message from a user process to the kernel.


       The kernel returns the SADB_FLUSH message to all listening sockets.


       Send a SADB_DUMP message from a user process to the kernel.


       Several SADB_DUMP messages returns  from  the  kernel  to  the  sending

         <base, SA, (lifetime (HSC),) address (SD), (address (Is,Id),)
            (address (Nl,Nr),) key (AE), (identity (SD),) sensitivity, outer sensitivity)>

       To  mark  the  end  of  a  dump  a  single base header arrives with its
       sadb_mdg_seq set to 0.


       Send a SADB_X_PROMISC message from a user process to the kernel.


       The kernel returns the SADB_X_PROMISC message  to  all  listening  pro‐


       The  message  returning  from the kernel contains a diagnostic value in
       the base message header,  the  diagnostic  value  indicates  if  action
       requested by the original message was a success.
