NAME
pf_key - Security association database interface
SYNOPSIS
#include <sys/types.h>
#include <sys/socket.h>
#include <net/pfkeyv2.h>
int socket(PF_KEY,SOCK_RAW,PF_KEY_V2);
DESCRIPTION
Keying information for IPsec security services is maintained in security 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
analogous to the method described in route(7P). Only a superuser may access an SADB.
SunOS applications that use PF_KEY include ipseckey(1M) and in.iked(1M).
The operating system may spontaneously send pf_key messages to listening 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 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.

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 illustrated as:
<base, REQUIRED EXTENSION, REQ., (OPTIONAL EXTENSION,) (OPT)>
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 selectors 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 will pro-
tect-and-transmit 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(7P)) socket option enabled.
Note that when an error occurs, only the base header is sent. In the event of an error, an extended diagnostic may be set (see DIAGNOS-
TICS). Typical errors include:
EINVAL Various message improprieties, including SPI ranges that are malformed, weak keys, and others. If EINVAL is returned, an appli-
cation 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 exists.
ESRCH SA could not be found.
The following are examples of message use and behavior:
SADB_GETSPI
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)>
SADB_UPDATE
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)>
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 will update the security association pair linkage with the SPI of the
security 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.
SADB_ADD
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) (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)>
SADB_X_UPDATEPAIR
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)>
SADB_DELETE | SADB_X_DELPAIR
Send a SADB_DELETE message from a user process to the kernel. The SADB_X_DELPAIR message type will request deletion of the security asso-
ciation 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)>
SADB_GET
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)>
SADB_ACQUIRE
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 will have a slightly different format. The sadb_msg_satype field is 0, and the extension contains the desired combina-
tion(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.
<base>
SADB_X_INVERSE_ACQUIRE
For inbound Key Management processing, a Key Management application may 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 ACQUIRE:
<base, address (SD), (address(Is,Id)), (identity(SD),)
(sensitivity,) eprop>
SADB_REGISTER
Send a SADB_REGISTER message from a user process to the kernel.
<base>
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 may arrive asynchronously due to an algorithm being loaded or unloaded into a dynami-
cally linked kernel.
<base, supported>
There is also the extended REGISTER, which will allow 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.
SADB_EXPIRE
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)>
SADB_FLUSH
Send a SADB_FLUSH message from a user process to the kernel.
<base>
The kernel returns the SADB_FLUSH message to all listening sockets.
<base>
SADB_DUMP
Send a SADB_DUMP message from a user process to the kernel.
<base>
Several SADB_DUMP messages will return from the kernel to the sending socket.
<base, SA, (lifetime (HSC),) address (SD), (address (Is,Id),)
(address (Nl,Nr),) key (AE), (identity (SD),) sensitivity)>
To mark the end of a dump a single base header arrives with its sadb_mdg_seq set to 0.
<base>
SADB_X_PROMISC
Send a SADB_X_PROMISC message from a user process to the kernel.
<base>
The kernel returns the SADB_X_PROMISC message to all listening processes.
<base>
DIAGNOSTICS
The message returning from the kernel will contain a diagnostic value in the base message header, the diagnostic value will indicate if
action requested by the original message was a success.
