-# -DKLIPS enables interface to Kernel LINUX IPsec code
-# -DDEBUG enables debugging code, allowing for debugging output
-# (note that output must also be selected at runtime, so it is
-# reasonable to always define this)
-# -DVENDORID enables Pluto to send out a VendorID payload.
-# this can be used by remote nodes to work around faults (bugs),
-# but is most useful to humans who are debugging things.
-# -DGCC_LINT uses gcc-specific declarations to improve compile-time
-# diagnostics.
-# -DLEAK_DETECTIVE enables crude code to find memory allocation leaks.
-# -DOLD_RESOLVER. At some point, the resolver interface changed.
-# This macro enables Pluto support for the old interface.
-# It is automatically defined, based on the value of the <resolver.h>
-# macro __RES. We don't know the correct threshold, so you may
-# find that you must manually define this. If so, please inform
-# us so that we can refine the threshold.
-# -DLIBCURL includes libcurl functions for the support of http-based protocols.
-# -DLDAP_VER includes openldap functions for the support of ldap-based queries.
-# LDAPv2 and LDAPv3 are supported.
-# -DTHREADS enables an asynchronous thread managing CRL fetching.
-# This option is activated either by -DLIBCURL or -DLDAP_VER.
-# -DSMARTCARD enables PKCS11-based smartcard support
-# -DPKCS11_DEFAULT_LIB defines a default PKCS11 library module which will be
-# loaded during runtime and is overridden by the pkcs11module parameter in
-# ipsec.conf. This option is activated by -DSMARTCARD.
-# -DI_KNOW_TRANSPORT_MODE_HAS_SECURITY_CONCERN_BUT_I_WANT_IT
-# allows IPsec transport mode in NAT-ed environments. Because of the
-# inherent security risks of such scenarios this options is deactivated
-# by default.
-
-# The following are best left undefined -- each can be overridden at runtime
-# if need be.
-# -DPORT=n sets the default UDP port for IKE messages (otherwise 500)
-# -DSHARED_SECRETS_FILE=string overrides /etc/ipsec.secrets as the
-# default name of the file containing secrets used to authenticate other
-# IKE daemons. In the Makefile, two levels of quoting are needed:
-# -DSHARED_SECRETS_FILE='"/etc/ipsec.secrets"'
-# -DDEFAULT_CTLBASE=string overrides /var/run/pluto as default directory
-# and basename for pluto's lockfile (.pid) and control socket (.ctl).
-# Double quoting may be needed.

-Notes on Pluto Conventions
-==========================
-
-RCSID $Id: PLUTO-CONVENTIONS,v 1.1 2004/03/15 20:35:28 as Exp $
-
-Pluto has its own stylistic conventions. They are fairly easily
-inferred by reading the code.
-
-- sample formatting:
-
-void
-fun(char *s)
-{
- if (s == NULL)
- {
- return "";
- }
- else
- {
- switch (*s)
- {
- default:
- s++;
- /* fall through */
- case '\0':
- return s;
- }
- }
-}
-
-- a function definition has its function identifier at the margin
-
-- indentation is in steps of 4 columns (tabstops are every 8 columns)
-
-- try to keep lines shorter than 80 columns
-
-- space should be canonical:
- + no line should have trailing whitespace
- + leading whitespace should use tabs where possible
- + indentation should be precise
- + there should be no empty lines at the end of a file.
-
-- braces go on their own line, indented the same as the start of what they are part of
-
-- switch labels are indented the same as the enclosing braces
-
-- if a case falls through, say so explicitly
-
-- spaces follow control flow reserved words (but not function names)
-
-- the operand of return need not be parenthesized
-
-- be careful with types. For example, use size_t and ssize_t.
- Use const wherever possible.
-
-- we pretend that C has a strong boolean type.
- We actually define bool with constants TRUE and FALSE.
- Other types cannot be used as the complete expression in a test.
- Hence:
- if (s == NULL)
- One exception: lset_t values can be treated as booleans
- (technically they are, in the original sense of the word)
-
-
-- memsetting a pointer to binary zero is not guaranteed to make it NULL
-
-- side-effects of expressions are to be avoided.
- BAD: if (i++ == 9)
- OK: i++;
-
-- variables are to have as small a scope as is possible.
- Move definitions into inner blocks whenever possible.
- Often initializing definitions become possible and are clearer.
-
-- within a block that has declarations, separate the declarations from
- the other statements with a blank line.
-
-- "magic numbers" are suspect. Most integers in code stand for something.
- They should be given a name, and that name used consistently.
-
-- don't use malloc/free -- use the wrappers (see defs.h)
-
-- it is good to put comments on #else and #endif to show what
- they match with. I use ! to indicate the sense of the test:
- #ifdef CRUD
- #else /* !CRUD */
- #endif /* !CRUD */
-
- #ifndef CRUD
- #else /* CRUD */
- #endif /* CRUD */
-
-- all functions and variables that are exported from a .c file should
- be declared in that file's header file. Because the .c includes the
- header, the declaration and the definition will be checked by the
- compiler. There is almost no excuse for the "extern" keyword
- in a .c file.
-
-- when lines are too long and expressions are to be broken, try to
- break just before a binary operator. The outermost binary operator
- is preferred. This is perhaps the most unconventional convention.
- It allows the structure of code to be evident from a scan of the
- left margin. Example:
- if (next_step == vos_his_client
- && sameaddr(&c->spd.that.host_addr, &his_client))
- next_step = vos_done;
- and
- p = oppo_instantiate(p, &c->spd.that.host_addr, &c->spd.that.id
- , NULL, &our_client, &his_client);
- Note the different indentation of the continuations. The continuation
- of a control flow statement is not indented but other continuations are.
-
-- Never put two statements on one line.
- REALLY BAD: if (cat);
- Exception: some macro definitions.
-
-- C preprocessor macros are implemented by a kind of textual substitution.
- Be sure to put parentheses around references to macro arguments and
- around the whole macro body. If the body is meant to be a statement,
- put braces around it instead.
-
- #define RETURN_STF_FAILURE(f) \
- { int r = (f); if (r != NOTHING_WRONG) return STF_FAIL + r; }
-
-- adding #include statements adds dependencies. The Makefile should be
- changed to reflect them. Target "makedepend" will try to list dependencies
- in a way suitable for pasting into Makefile

-Pluto TODO list
-===============
-RCSID $Id: TODO,v 1.1 2004/03/15 20:35:28 as Exp $
-
-- should all log entries that are for errors say ERROR?
-
-- Add a "plug-in" facility so that others can add features without
- changing the mainline code. This is how X509/LDAP/biometric stuff
- might be added.
-
-- (internal change only) routines for outputting payloads should plug
- "np" into the previous payload so that a payload generating routine
- need not know what the next payload will be. This may be more bother
- than it is worth.
-
-- notifications, in and out
- + delete
- + first contact
- + last contact? (not part of drafts, but would be nice)
-
-- Make DNS usage for asynchronous (non-blocking)
- + looking up KEY and TXT records during negotiation
- + perhaps not for whack command arguments and ipsec.secrets since the
- library code uses gethostbyname
-
-- check that ipsec auto and whack to agree on what is worth reporting
-
-- Should Pluto (rather than ipsec manual) install %passthrough conns?
- That way Pluto would know of them.
-
-- For responding to Road Warriors, how can we decide if the RW has
- gone away? The rekeying event is perhaps too imprecise. Even if
- rekeying event is good enough, how do we know if the route should be
- torn down? Perhaps limiting a Phase 1 ID to one IP address would
- help (limiting a client subnet to one peer already helps). Perhaps
- (in some rate-limited way) we can take an ICMP host unreachable
- as a hint to do some authenticated and reliable probe.
-
-- it is annoying that Pluto and auto have different models for public keys.
- + auto specifies one per connection
- + Pluto allows one to be specified per id
- Two connections with the same id are going to use the same key:
- the one of the last conn to be added!
-
- I think auto ought to be fixed. It is hard for Pluto to warn when
- there is a conflict since the deletion of a connection doesn't
- prompt auto to tell pluto to delete the public key.
-
-- different connections with the same host IP addresses are randomly
- interchangeable until the ID payload is received. At least for the
- Responder case (and eventually for the opportunistic Initiator).
- Worse, all Road Warriors must be considered to have the
- indistinguishable IP addresses. This affects ISAKMP SA negotiation.
- Currently, there is little flexibility in this negotiation, so the
- problem is limited to the specification of acceptable authentication
- method(s). Correct, but more work than seems worthwhile, would be
- to select the conn based on what is proposed.
-
- Warning about such confusion at connection definition time isn't great
- because there is no confusion when explicitly initiated (a particular
- conn is specified). Warning for a Road Warrior conn is possible
- since it cannot be initiated (and has been implemented).
-
-- characterize and ameliorate DOS attacks. Lots of rate limiting.
-
-- look at John Denker's wish list: http://www.quintillion.com/moat/wish.list
-
-- use of random numbers needs to be audited.
-
-- unknown (not just unimplemented) transforms cause a negotiation to
- fail. Only the transform should be rejected.
-
-- we need better policy control. Our present flags need to be
- modulated (forbid, allow, offer, require)
-
-- HS will specify how --copyright and --version should behave
-
-- HS will initiate project-wide terminology replacing ISAKMP SA, IPSEC
- SA, Protection Suite, Phase 1, Main Mode, Phase 2, Quick Mode, ...
- Simplicity and clarity will be a goal.
-
-- interface discovery ought to match what is specified in ipsec.conf.
- This probably means grokking /proc/net/ipsec_tncfg. Documented in
- ipsec_tncfg(5). This won't do for Hugh's debugging setup.
-
-
-Protocol Issues
-===============
-
-Notification and delete payloads seem to be "escape hatches" for the
-protocols. As such, anything implemented using them seems to be
-kludged without being well designed or well situated or well
-constrained in the protocols. Often the precise meaning (if any) or
-usage is under specified. An implementation is allowed to ignore
-them, so they cannot really matter (but they too often do). Their
-specification ought to be scrutinized by a protocol guru.
-
-Any extra payload in last main mode message is not protected (not
-authenticated by hash).
-
-Should notification payloads be interpreted before or after the normal
-payloads (i.e. understood in the context of, executed in the context of).
-
-What is the precise result of an INITIAL_CONNECTION? What is a
-"system" (eg. does Phase 1 Identity count)? What is "earlier" or
-"before" (simultaneous negotiation is possible, with time being only a
-partial order)? Could it be used for FINAL_CONTACT (needed too)?
-
-Blasting out a pile of UDP messages, especially to a particular
-destination, is likely to provoke message loss. The exchanges are
-just that, so they individually are self-throttling. But what about
-multiple exchanges simultaneously? What about notifications (example:
-when shutting down, a flurry of delete notifications are likely).
-Should the RFCs be designed to protect against this problem?
-
-draft-jenkins-ipsec-rekeying-03.txt rekeying is way too complicated.
-Our solution looks sound and simple (we have the Responder install the
-incoming IPSEC SA before sending its first reply). In "2.2.1.4
-Responder Pre-Set-up Security Hole", the draft claims that setting up
-the IPSEC SA early leaves the Responder open to replay attacks. I
-think that this is wrong: the Message Id, since it must not be reused,
-serves to prove that this isn't a replay.
-
-The details for notification messages suggested by
-draft-ietf-ipsec-notifymsg-02.txt are over-complicated, just to make
-them machine-comprehensible. I think this is over-engineering,
-justified only if another level of negotiation is contemplated (ugh!).
-Plain text is probably sufficient for informing humans (I admit that
-there is a problem with I18N).

- * At most MAX_WORKERS will be created; after that, the Master will queue
- * queries until a Worker becomes free. When a Worker has an answer from
- * the resolver, it sends the answer as a struct adns_answer message to the
- * Master. The Master then forwards the answer to Pluto, noting that
- * the Worker is free to accept another query.
- *
- * The protocol is simple: Pluto sends a sequence of queries and receives
- * a sequence of answers. select(2) is used by Pluto and by the Master
- * process to decide when to read, but writes are done without checking
- * for readiness. Communications is via pipes. Since only one process
- * can write to each pipe, messages will not be interleaved. Fixed length
- * records are used for simplicity.
- *
- * Pluto needs a way to indicate to the Master when to shut down
- * and the Master needs to indicate this to each worker. EOF on the pipe
- * signifies this.
- *
- * The interfaces between these components are considered private to
- * Pluto. This allows us to get away with less checking. This is a
- * reason to use pipes instead of TCP/IP.
- *
- * Although the code uses plain old UNIX processes, it could be modified
- * to use threads. That might reduce resource requirements. It would
- * preclude running on systems without thread-safe resolvers.

-/* There are two kinds of connections:
- * - ISAKMP connections, between hosts (for IKE communication)
- * - IPsec connections, between clients (for secure IP communication)
- *
- * An ISAKMP connection looks like:
- * host<--->host
- *
- * An IPsec connection looks like:
- * client-subnet<-->host<->nexthop<--->nexthop<->host<-->client-subnet
- *
- * For the connection to be relevant to this instance of Pluto,
- * exactly one of the hosts must be a public interface of our machine
- * known to this instance.
- *
- * The client subnet might simply be the host -- this is a
- * representation of "host mode".
- *
- * Each nexthop defaults to the neighbouring host's IP address.
- * The nexthop is a property of the pair of hosts, not each
- * individually. It is only needed for IPsec because of the
- * way IPsec is mixed into the kernel routing logic. Furthermore,
- * only this end's nexthop is actually used. Eventually, nexthop
- * will be unnecessary.
- *
- * Other information represented:
- * - each connection has a name: a chunk of uninterpreted text
- * that is unique for each connection.
- * - security requirements (currently just the "policy" flags from
- * the whack command to initiate the connection, but eventually
- * much more. Different for ISAKMP and IPsec connections.
- * - rekeying parameters:
- * + time an SA may live
- * + time before SA death that a rekeying should be attempted
- * (only by the initiator)
- * + number of times to attempt rekeying
- * - With the current KLIPS, we must route packets for a client
- * subnet through the ipsec interface (ipsec0). Only one
- * gateway can get traffic for a specific (client) subnet.
- * Furthermore, if the routing isn't in place, packets will
- * be sent in the clear.
- * "routing" indicates whether the routing has been done for
- * this connection. Note that several connections may claim
- * the same routing, as long as they agree about where the
- * packets are to be sent.
- * - With the current KLIPS, only one outbound IPsec SA bundle can be
- * used for a particular client. This is due to a limitation
- * of using only routing for selection. So only one IPsec state (SA)
- * may "own" the eroute. "eroute_owner" is the serial number of
- * this state, SOS_NOBODY if there is none. "routing" indicates
- * what kind of erouting has been done for this connection, if any.
- *
- * Details on routing is in constants.h
- *
- * Operations on Connections:
- *
- * - add a new connection (with all details) [whack command]
- * - delete a connection (by name) [whack command]
- * - initiate a connection (by name) [whack command]
- * - find a connection (by IP addresses of hosts)
- * [response to peer request; finding ISAKMP connection for IPsec connection]
- *
- * Some connections are templates, missing the address of the peer
- * (represented by INADDR_ANY). These are always arranged so that the
- * missing end is "that" (there can only be one missing end). These can
- * be instantiated (turned into real connections) by Pluto in one of two
- * different ways: Road Warrior Instantiation or Opportunistic
- * Instantiation. A template connection is marked for Opportunistic
- * Instantiation by specifying the peer client as 0.0.0.0/32 (or the IPV6
- * equivalent). Otherwise, it is suitable for Road Warrior Instantiation.
- *
- * Instantiation creates a new temporary connection, with the missing
- * details filled in. The resulting template lasts only as long as there
- * is a state that uses it.

-/* connection policy priority: how important this policy is
- * - used to implement eroute-like precedence (augmented by a small
- * bonus for a routed connection).

- * - three subcomponents. In order of decreasing significance:
- * + length of source subnet mask (8 bits)
- * + length of destination subnet mask (8 bits)
- * + bias (8 bit)
- * - a bias of 1 is added to allow prio BOTTOM_PRIO to be less than all
- * normal priorities
- * - other bias values are created on the fly to give mild preference
- * to certaion conditions (eg. routedness)
- * - priority is inherited -- an instance of a policy has the same priority

- * "In Quick Mode, a HASH payload MUST immediately follow the ISAKMP
- * header and a SA payload MUST immediately follow the HASH."
- * [NOTE: there may be more than one SA payload, so this is not
- * totally reasonable. Probably all SAs should be so constrained.]
- *
- * "If ISAKMP is acting as a client negotiator on behalf of another
- * party, the identities of the parties MUST be passed as IDci and
- * then IDcr."
- *
- * "With the exception of the HASH, SA, and the optional ID payloads,
- * there are no payload ordering restrictions on Quick Mode."
- */
-
-/* Unfolding of Identity -- a central mystery
- *
- * This concerns Phase 1 identities, those of the IKE hosts.
- * These are the only ones that are authenticated. Phase 2
- * identities are for IPsec SAs.
- *
- * There are three case of interest:
- *
- * (1) We initiate, based on a whack command specifying a Connection.
- * We know the identity of the peer from the Connection.
- *
- * (2) (to be implemented) we initiate based on a flow from our client
- * to some IP address.
- * We immediately know one of the peer's client IP addresses from
- * the flow. We must use this to figure out the peer's IP address
- * and Id. To be solved.
- *
- * (3) We respond to an IKE negotiation.
- * We immediately know the peer's IP address.
- * We get an ID Payload in Main I2.
- *
- * Unfortunately, this is too late for a number of things:
- * - the ISAKMP SA proposals have already been made (Main I1)
- * AND one accepted (Main R1)
- * - the SA includes a specification of the type of ID
- * authentication so this is negotiated without being told the ID.
- * - with Preshared Key authentication, Main I2 is encrypted
- * using the key, so it cannot be decoded to reveal the ID
- * without knowing (or guessing) which key to use.
- *
- * There are three reasonable choices here for the responder:
- * + assume that the initiator is making wise offers since it
- * knows the IDs involved. We can balk later (but not gracefully)
- * when we find the actual initiator ID
- * + attempt to infer identity by IP address. Again, we can balk
- * when the true identity is revealed. Actually, it is enough
- * to infer properties of the identity (eg. SA properties and
- * PSK, if needed).
- * + make all properties universal so discrimination based on
- * identity isn't required. For example, always accept the same
- * kinds of encryption. Accept Public Key Id authentication
- * since the Initiator presumably has our public key and thinks
- * we must have / can find his. This approach is weakest
- * for preshared key since the actual key must be known to
- * decrypt the Initiator's ID Payload.
- * These choices can be blended. For example, a class of Identities
- * can be inferred, sufficient to select a preshared key but not
- * sufficient to infer a unique identity.

- * ??? how long can the messge be?
- *
- * ??? poll(2) has a very incomplete description of the POLL* events.
- * We assume that POLLIN, POLLOUT, and POLLERR are all we need to deal with
- * and that POLLERR will be on iff there is a MSG_ERRQUEUE message.
- *
- * We have to code around a couple of surprises:
- *
- * - Select can say that a socket is ready to read from, and
- * yet a read will hang. It turns out that a message available on the
- * MSG_ERRQUEUE will cause select to say something is pending, but
- * a normal read will hang. poll(2) can tell when a MSG_ERRQUEUE
- * message is pending.
- *
- * This is dealt with by calling check_msg_errqueue after select
- * has indicated that there is something to read, but before the
- * read is performed. check_msg_errqueue will return TRUE if there
- * is something left to read.
- *
- * - A write to a socket may fail because there is a pending MSG_ERRQUEUE
- * message, without there being anything wrong with the write. This
- * makes for confusing diagnostics.
- *
- * To avoid this, we call check_msg_errqueue before a write. True,
- * there is a race condition (a MSG_ERRQUEUE message might arrive

-.TH IPSEC.SECRETS 5 "28 March 1999"
-.SH NAME
-ipsec.secrets \- secrets for IKE/IPsec authentication
-.SH DESCRIPTION
-The file \fIipsec.secrets\fP holds a table of secrets.
-These secrets are used by \fIipsec_pluto\fP(8), the FreeS/WAN Internet Key
-Exchange daemon, to authenticate other hosts.
-Currently there are two kinds of secrets: preshared secrets and
-.\" the private part of DSS keys.
-RSA private keys.
-.LP
-It is vital that these secrets be protected. The file should be owned
-by the super-user,
-and its permissions should be set to block all access by others.
-.LP
-The file is a sequence of entries and include directives.
-Here is an example. Each entry or directive must start at the
-left margin, but if it continues beyond a single line, each continuation
-line must be indented.
-.LP
-.RS

-# sample /etc/ipsec.secrets file for 10.1.0.1

-# but indentation matters

-.RE
-.LP
-Each entry in the file is a list of indices, followed by a secret.
-The two parts are separated by a colon (\fB:\fP) that is
-followed by whitespace or a newline. For compatability
-with the previous form of this file, if the key part is just a
-double-quoted string the colon may be left out.
-.LP
-An index is an IP address, or a Fully Qualified Domain Name, user@FQDN,
-\fB%any\fP or \fB%any6\fP (other kinds may come). An IP address may be written
-in the familiar dotted quad form or as a domain name to be looked up
-when the file is loaded
-(or in any of the forms supported by the FreeS/WAN \fIipsec_ttoaddr\fP(3)
-routine). In many cases it is a bad idea to use domain names because
-the name server may not be running or may be insecure. To denote a
-Fully Qualified Domain Name (as opposed to an IP address denoted by
-its domain name), precede the name with an at sign (\fB@\fP).
-.LP
-Matching IDs with indices is fairly straightforward: they have to be
-equal. In the case of a ``Road Warrior'' connection, if an equal
-match is not found for the Peer's ID, and it is in the form of an IP
-address, an index of \fB%any\fP will match the peer's IP address if IPV4
-and \fB%any6\fP will match a the peer's IP address if IPV6.
-Currently, the obsolete notation \fB0.0.0.0\fP may be used in place of
-\fB%any\fP.
-.LP
-An additional complexity
-arises in the case of authentication by preshared secret: the
-responder will need to look up the secret before the Peer's ID payload has
-been decoded, so the ID used will be the IP address.
-.LP
-To authenticate a connection between two hosts, the entry that most
-specifically matches the host and peer IDs is used. An entry with no
-index will match any host and peer. More specifically, an entry with one index will
-match a host and peer if the index matches the host's ID (the peer isn't
-considered). Still more specifically, an entry with multiple indices will match a host and
-peer if the host ID and peer ID each match one of the indices. If the key
-is for an asymmetric authentication technique (i.e. a public key
-system such as RSA), an entry with multiple indices will match a host
-and peer even if only the host ID matches an index (it is presumed that the
-multiple indices are all identities of the host).
-It is acceptable for two entries to be the best match as
-long as they agree about the secret or private key.
-.LP
-Authentication by preshared secret requires that both systems find the
-identical secret (the secret is not actually transmitted by the IKE
-protocol). If both the host and peer appear in the index list, the
-same entry will be suitable for both systems so verbatim copying
-between systems can be used. This naturally extends to larger groups
-sharing the same secret. Thus multiple-index entries are best for PSK
-authentication.
-.LP
-Authentication by RSA Signatures requires that each host have its own private
-key. A host could reasonably use a different private keys
-for different interfaces and for different peers. But it would not
-be normal to share entries between systems. Thus thus no-index and
-one-index forms of entry often make sense for RSA Signature authentication.
-.LP
-The key part of an entry may start with a token indicating the kind of
-key. ``RSA'' signifies RSA private key and ``PSK'' signifies
-PreShared Key (case is ignored). For compatability with previous
-forms of this file, PSK is the default.
-.LP
-A preshared secret is most conveniently represented as a sequence of
-characters, delimited by the double-quote
-character (\fB"\fP). The sequence cannot contain a newline or
-double-quote. Strictly speaking, the secret is actually the sequence
-of bytes that is used in the file to represent the sequence of
-characters (excluding the delimiters).
-A preshared secret may also be represented, without quotes, in any form supported by
-\fIipsec_ttodata\fP(3).
-.LP
-An RSA private key is a composite of eight generally large numbers. The notation
-used is a brace-enclosed list of field name and value pairs (see the example above).
-A suitable key, in a suitable format, may be generated by \fIipsec_rsasigkey\fP(8).
-The structure is very similar to that used by BIND 8.2.2 or later, but note that
-the numbers must have a ``0s'' prefix if they are in base 64. The order of
-the fields is fixed.
-.LP
-The first token an entry must start in
-the first column of its line. Subsequent tokens must be
-separated by whitespace,
-except for a colon token, which only needs to be followed by whitespace.
-A newline is taken as whitespace, but every
-line of an entry after the first must be indented.
-.LP
-Whitespace at the end of a line is ignored (except in the 0t
-notation for a key). At the start of line or
-after whitespace, \fB#\fP and the following text up to the end of the
-line is treated as a comment. Within entries, all lines must be
-indented (except for lines with no tokens).
-Outside entries, no line may be indented (this is to make sure that
-the file layout reflects its structure).
-.LP
-An include directive causes the contents of the named file to be processed
-before continuing with the current file. The filename is subject to
-``globbing'' as in \fIsh\fP(1), so every file with a matching name
-is processed. Includes may be nested to a modest
-depth (10, currently). If the filename doesn't start with a \fB/\fP, the
-directory containing the current file is prepended to the name. The
-include directive is a line that starts with the word \fBinclude\fP,
-followed by whitespace, followed by the filename (which must not contain
-whitespace).

- * matches. We need not check the public key if
- * it isn't in the TXT record.
- *
- * Since p isn't yet instantiated, we need to look

- * separate token. If preceded by whitespace, a "#" is taken as starting
- * a comment: it and the rest of the line are ignored.
- *
- * One kind of record is an include directive. It starts with "include".
- * The filename is the only other token in the record.
- * If the filename does not start with /, it is taken to
- * be relative to the directory containing the current file.
- *
- * The other kind of record describes a key. It starts with a
- * sequence of ids and ends with key information. Each id
- * is an IP address, a Fully Qualified Domain Name (which will immediately
- * be resolved), or @FQDN which will be left as a name.
- *
- * The key part can be in several forms.
- *
- * The old form of the key is still supported: a simple
- * quoted strings (with no escapes) is taken as a preshred key.
- *
- * The new form starts the key part with a ":".
- *
- * For Preshared Key, use the "PSK" keyword, and follow it by a string
- * or a data token suitable for ttodata(3).
- *
- * For RSA Private Key, use the "RSA" keyword, followed by a
- * brace-enclosed list of key field keywords and data values.
- * The data values are large integers to be decoded by ttodata(3).
- * The fields are a subset of those used by BIND 8.2 and have the

- * Although the drafts are a little unclear, there are a few

- *
- * RFC 2408 "ISAKMP" 3.6 specifies that all messages will be
- * padded to be a multiple of 4 octets in length.
- * ??? This looks vestigial, and we ignore this requirement.
- *
- * RFC 2409 "IKE" Appedix B specifies:
- * Each message should be padded up to the nearest block size
- * using bytes containing 0x00.
- * ??? This does not appear to be limited to encrypted messages,
- * but it surely must be: the block size is meant to be the encryption
- * block size, and that is meaningless for a non-encrypted message.
- *
- * RFC 2409 "IKE" 5.3 specifies:
- * Encrypted payloads are padded up to the nearest block size.
- * All padding bytes, except for the last one, contain 0x00. The
- * last byte of the padding contains the number of the padding
- * bytes used, excluding the last one. Note that this means there
- * will always be padding.
- * ??? This is nuts since payloads are not padded, messages are.
- * It also contradicts Appendix B. So we ignore it.
- *
- * Summary: we pad encrypted output messages with 0x00 to bring them
- * up to a multiple of the encryption block size. On input, we require
- * that any encrypted portion of a message be a multiple of the encryption
- * block size. After any decryption, we ignore padding (any bytes after
- * the first payload that specifies a next payload of none; we don't
- * require them to be zero).

-.SH DESCRIPTION
-.BR pluto
-is an IKE (``IPsec Key Exchange'') daemon.
-.BR whack
-is an auxiliary program to allow requests to be made to a running
-.BR pluto .
-.LP
-.BR pluto
-is used to automatically build shared ``security associations'' on a
-system that has IPsec, the secure IP protocol.
-In other words,
-.BR pluto
-can eliminate much of the work of manual keying.
-The actual
-secure transmission of packets is the responsibility of other parts of
-the system (see
-.BR KLIPS ,
-the companion implementation of IPsec).
-\fIipsec_auto\fP(8) provides a more convenient interface to
-\fBpluto\fP and \fBwhack\fP.
-.SS IKE's Job
-.LP
-A \fISecurity Association\fP (\fISA\fP) is an agreement between two network nodes on
-how to process certain traffic between them. This processing involves
-encapsulation, authentication, encryption, or compression.
-.LP
-IKE can be deployed on a network node to negotiate Security
-Associations for that node. These IKE implementations can only
-negotiate with other IKE implementations, so IKE must be on each node
-that is to be an endpoint of an IKE-negotiated Security Association.
-No other nodes need to be running IKE.
-.LP
-An IKE instance (i.e. an IKE implementation on a particular network
-node) communicates with another IKE instance using UDP IP packets, so
-there must be a route between the nodes in each direction.
-.LP
-The negotiation of Security Associations requires a number of choices
-that involve tradeoffs between security, convenience, trust, and
-efficiency. These are policy issues and are normally specified to the
-IKE instance by the system administrator.
-.LP
-IKE deals with two kinds of Security Associations. The first part of
-a negotiation between IKE instances is to build an ISAKMP SA. An
-ISAKMP SA is used to protect communication between the two IKEs.
-IPsec SAs can then be built by the IKEs \- these are used to carry
-protected IP traffic between the systems.
-.LP
-The negotiation of the ISAKMP SA is known as Phase 1. In theory,
-Phase 1 can be accomplished by a couple of different exchange types,
-but we only implement one called Main Mode (we don't implement
-Aggressive Mode).
-.LP
-Any negotiation under the protection of an ISAKMP SA, including the
-negotiation of IPsec SAs, is part of Phase 2. The exchange type
-that we use to negotiate an IPsec SA is called Quick Mode.
-.LP
-IKE instances must be able to authenticate each other as part of their
-negotiation of an ISAKMP SA. This can be done by several mechanisms
-described in the draft standards.
-.LP
-IKE negotiation can be initiated by any instance with any other. If
-both can find an agreeable set of characteristics for a Security
-Association, and both recognize each others authenticity, they can set
-up a Security Association. The standards do not specify what causes
-an IKE instance to initiate a negotiation.
-.LP
-In summary, an IKE instance is prepared to automate the management of
-Security Associations in an IPsec environment, but a number of issues
-are considered policy and are left in the system administrator's hands.
-.SS Pluto
-.LP
-\fBpluto\fP is an implementation of IKE. It runs as a daemon on a network
-node. Currently, this network node must be a LINUX system running the
-\fBKLIPS\fP implementation of IPsec.
-.LP
-\fBpluto\fP only implements a subset of IKE. This is enough for it to
-interoperate with other instances of \fBpluto\fP, and many other IKE
-implementations. We are working on implementing more of IKE.
-.LP
-The policy for acceptable characteristics for Security Associations is
-mostly hardwired into the code of \fBpluto\fP (spdb.c). Eventually
-this will be moved into a security policy database with reasonable
-expressive power and more convenience.
-.LP
-\fBpluto\fP uses shared secrets or RSA signatures to authenticate
-peers with whom it is negotiating.
-.LP
-\fBpluto\fP initiates negotiation of a Security Association when it is
-manually prodded: the program \fBwhack\fP is run to trigger this.
-It will also initiate a negotiation when \fBKLIPS\fP traps an outbound packet
-for Opportunistic Encryption.
-.LP
-\fBpluto\fP implements ISAKMP SAs itself. After it has negotiated the
-characteristics of an IPsec SA, it directs \fBKLIPS\fP to implement it.
-It also invokes a script to adjust any firewall and issue \fIroute\fP(8)
-commands to direct IP packets through \fBKLIPS\fP.
-.LP
-When \fBpluto\fP shuts down, it closes all Security Associations.
-.SS Before Running Pluto
-.LP
-\fBpluto\fP runs as a daemon with userid root. Before running it, a few
-things must be set up.
-.LP
-\fBpluto\fP requires \fBKLIPS\fP, the FreeS/WAN implementation of IPsec.
-All of the components of \fBKLIPS\fP and \fBpluto\fP should be installed.
-.LP
-\fBpluto\fP supports multiple public networks (that is, networks
-that are considered insecure and thus need to have their traffic
-encrypted or authenticated). It discovers the
-public interfaces to use by looking at all interfaces that are
-configured (the \fB\-\-interface\fP option can be used to limit
-the interfaces considered).
-It does this only when \fBwhack\fP tells it to \-\-listen,
-so the interfaces must be configured by then. Each interface with a name of the form
-\fBipsec\fP[\fB0\fP-\fB9\fP] is taken as a \fBKLIPS\fP virtual public interface.
-Another network interface with the same IP address (there should be only
-one) is taken as the corresponding real public
-interface. \fIifconfig\fP(8) with the \fB\-a\fP flag will show
-the name and status of each network interface.
-.LP
-\fBpluto\fP requires a database of preshared secrets and RSA private keys.
-This is described in the
-.IR ipsec.secrets (5).
-\fBpluto\fP is told of RSA public keys via \fBwhack\fP commands.
-If the connection is Opportunistic, and no RSA public key is known,
-\fBpluto\fP will attempt to fetch RSA keys using the Domain Name System.
-.SS Setting up \fBKLIPS\fP for \fBpluto\fP
-.LP
-The most basic network topology that \fBpluto\fP supports has two security
-gateways negotiating on behalf of client subnets. The diagram of RGB's
-testbed is a good example (see \fIklips/doc/rgb_setup.txt\fP).
-.LP
-The file \fIINSTALL\fP in the base directory of this distribution
-explains how to start setting up the whole system, including \fBKLIPS\fP.
-.LP
-Make sure that the security gateways have routes to each other. This
-is usually covered by the default route, but may require issuing
-.IR route (8)
-commands. The route must go through a particular IP
-interface (we will assume it is \fIeth0\fP, but it need not be). The
-interface that connects the security gateway to its client must be a
-different one.
-.LP
-It is necessary to issue a
-.IR ipsec_tncfg (8)
-command on each gateway. The required command is:
-
-\ \ \ ipsec tncfg \-\-attach\ \-\-virtual\ ipsec0 \-\-physical\ eth0
-
-A command to set up the ipsec0 virtual interface will also need to be
-run. It will have the same parameters as the command used to set up
-the physical interface to which it has just been connected using
-.IR ipsec_tncfg (8).
-.SS ipsec.secrets file
-.LP
-A \fBpluto\fP daemon and another IKE daemon (for example, another instance
-of \fBpluto\fP) must convince each other that they are who they are supposed
-to be before any negotiation can succeed. This authentication is
-accomplished by using either secrets that have been shared beforehand
-(manually) or by using RSA signatures. There are other techniques,
-but they have not been implemented in \fBpluto\fP.
-.LP
-The file \fI/etc/ipsec.secrets\fP is used to keep preshared secret keys
-and RSA private keys for
-authentication with other IKE daemons. For debugging, there is an
-argument to the \fBpluto\fP command to use a different file.
-This file is described in
-.IR ipsec.secrets (5).
-.SS Running Pluto
-.LP
-To fire up the daemon, just type \fBpluto\fP (be sure to be running as
-the superuser).
-The default IKE port number is 500, the UDP port assigned by IANA for IKE Daemons.
-\fBpluto\fP must be run by the superuser to be able to use the UDP 500 port.
-.LP
-\fBpluto\fP attempts to create a lockfile with the name
-\fI/var/run/pluto.pid\fP. If the lockfile cannot be created,
-\fBpluto\fP exits \- this prevents multiple \fBpluto\fPs from
-competing Any ``leftover'' lockfile must be removed before
-\fBpluto\fP will run. \fBpluto\fP writes its pid into this file so
-that scripts can find it. This lock will not function properly if it
-is on an NFS volume (but sharing locks on multiple machines doesn't
-make sense anyway).
-.LP
-\fBpluto\fP then forks and the parent exits. This is the conventional
-``daemon fork''. It can make debugging awkward, so there is an option
-to suppress this fork.
-.LP
-All logging, including diagnostics, is sent to
-.IR syslog (3)
-with facility=authpriv;
-it decides where to put these messages (possibly in /var/log/secure).
-Since this too can make debugging awkward, there is an option to
-steer logging to stderr.
-.LP
-If the \fB\-\-perpeerlog\fP option is given, then pluto will open
-a log file per connection. By default, this is in /var/log/pluto/peer,
-in a subdirectory formed by turning all dot (.) [IPv4} or colon (:)
-[IPv6] into slashes (/).
-.LP
-The base directory can be changed with the \fB\-\-perpeerlogbase\fP.
-.LP
-Once \fBpluto\fP is started, it waits for requests from \fBwhack\fP.
-.SS Pluto's Internal State
-.LP
-To understand how to use \fBpluto\fP, it is helpful to understand a little
-about its internal state. Furthermore, the terminology is needed to decipher
-some of the diagnostic messages.
-.LP
-The \fI(potential) connection\fP database describes attributes of a
-connection. These include the IP addresses of the hosts and client
-subnets and the security characteristics desired. \fBpluto\fP
-requires this information (simply called a connection) before it can
-respond to a request to build an SA. Each connection is given a name
-when it is created, and all references are made using this name.
-.LP
-During the IKE exchange to build an SA, the information about the
-negotiation is represented in a \fIstate object\fP. Each state object
-reflects how far the negotiation has reached. Once the negotiation is
-complete and the SA established, the state object remains to represent
-the SA. When the SA is terminated, the state object is discarded.
-Each State object is given a serial number and this is used to refer
-to the state objects in logged messages.
-.LP
-Each state object corresponds to a connection and can be thought of
-as an instantiation of that connection.
-At any particular time, there may be any number of state objects
-corresponding to a particular connection.
-Often there is one representing an ISAKMP SA and another representing
-an IPsec SA.
-.LP
-\fBKLIPS\fP hooks into the routing code in a LINUX kernel.
-Traffic to be processed by an IPsec SA must be directed through
-\fBKLIPS\fP by routing commands. Furthermore, the processing to be
-done is specified by \fIipsec eroute(8)\fP commands.
-\fBpluto\fP takes the responsibility of managing both of these special
-kinds of routes.
-.LP
-Each connection may be routed, and must be while it has an IPsec SA.
-The connection specifies the characteristics of the route: the
-interface on this machine, the ``gateway'' (the nexthop),
-and the peer's client subnet. Two
-connections may not be simultaneously routed if they are for the same
-peer's client subnet but use different interfaces or gateways
-(\fBpluto\fP's logic does not reflect any advanced routing capabilities).
-.LP
-Each eroute is associated with the state object for an IPsec SA
-because it has the particular characteristics of the SA.
-Two eroutes conflict if they specify the identical local
-and remote clients (unlike for routes, the local clients are
-taken into account).
-.LP
-When \fBpluto\fP needs to install a route for a connection,
-it must make sure that no conflicting route is in use. If another
-connection has a conflicting route, that route will be taken down, as long
-as there is no IPsec SA instantiating that connection.
-If there is such an IPsec SA, the attempt to install a route will fail.
-.LP
-There is an exception. If \fBpluto\fP, as Responder, needs to install
-a route to a fixed client subnet for a connection, and there is
-already a conflicting route, then the SAs using the route are deleted
-to make room for the new SAs. The rationale is that the new
-connection is probably more current. The need for this usually is a
-product of Road Warrior connections (these are explained later; they
-cannot be used to initiate).
-.LP
-When \fBpluto\fP needs to install an eroute for an IPsec SA (for a
-state object), first the state object's connection must be routed (if
-this cannot be done, the eroute and SA will not be installed).
-If a conflicting eroute is already in place for another connection,
-the eroute and SA will not be installed (but note that the routing
-exception mentioned above may have already deleted potentially conflicting SAs).
-If another IPsec
-SA for the same connection already has an eroute, all its outgoing traffic
-is taken over by the new eroute. The incoming traffic will still be
-processed. This characteristic is exploited during rekeying.
-.LP
-All of these routing characteristics are expected change when
-\fBKLIPS\fP is modified to use the firewall hooks in the LINUX 2.4.x
-kernel.
-.SS Using Whack
-.LP
-\fBwhack\fP is used to command a running \fBpluto\fP.
-\fBwhack\fP uses a UNIX domain socket to speak to \fBpluto\fP
-(by default, \fI/var/pluto.ctl\fP).
-.LP
-\fBwhack\fP has an intricate argument syntax.
-This syntax allows many different functions to be specified.
-The help form shows the usage or version information.
-The connection form gives \fBpluto\fP a description of a potential connection.
-The public key form informs \fBpluto\fP of the RSA public key for a potential peer.
-The delete form deletes a connection description and all SAs corresponding
-to it.
-The listen form tells \fBpluto\fP to start or stop listening on the public interfaces
-for IKE requests from peers.
-The route form tells \fBpluto\fP to set up routing for a connection;
-the unroute form undoes this.
-The initiate form tells \fBpluto\fP to negotiate an SA corresponding to a connection.
-The terminate form tells \fBpluto\fP to remove all SAs corresponding to a connection,
-including those being negotiated.
-The status form displays the \fBpluto\fP's internal state.
-The debug form tells \fBpluto\fP to change the selection of debugging output
-``on the fly''. The shutdown form tells
-\fBpluto\fP to shut down, deleting all SAs.
-.LP
-Most options are specific to one of the forms, and will be described
-with that form. There are three options that apply to all forms.
-.TP
-\fB\-\-ctlbase\fP\ \fIpath\fP
-\fIpath\fP.ctl is used as the UNIX domain socket for talking
-to \fBpluto\fP.
-This option facilitates debugging.
-.TP
-\fB\-\-optionsfrom\fP\ \fIfilename\fP
-adds the contents of the file to the argument list.
-.TP
-\fB\-\-label\fP\ \fIstring\fP
-adds the string to all error messages generated by \fBwhack\fP.
-.LP
-The help form of \fBwhack\fP is self-explanatory.
-.TP
-\fB\-\-help\fP
-display the usage message.
-.TP
-\fB\-\-version\fP
-display the version of \fBwhack\fP.
-.LP
-The connection form describes a potential connection to \fBpluto\fP.
-\fBpluto\fP needs to know what connections can and should be negotiated.
-When \fBpluto\fP is the initiator, it needs to know what to propose.
-When \fBpluto\fP is the responder, it needs to know enough to decide whether
-is is willing to set up the proposed connection.
-.LP
-The description of a potential connection can specify a large number
-of details. Each connection has a unique name. This name will appear
-in a updown shell command, so it should not contain punctuation
-that would make the command ill-formed.
-.TP
-\fB\-\-name\fP\ \fIconnection-name\fP
-.LP
-The topology of
-a connection is symmetric, so to save space here is half a picture:
-
-\ \ \ client_subnet<\-\->host:ikeport<\-\->nexthop<\-\-\-
-
-A similar trick is used in the flags. The same flag names are used for
-both ends. Those before the \fB\-\-to\fP flag describe the left side
-and those afterwards describe the right side. When \fBpluto\fP attempts
-to use the connection, it decides whether it is the left side or the right
-side of the connection, based on the IP numbers of its interfaces.
-.TP
-\fB\-\-id\fP\ \fIid\fP
-the identity of the end. Currently, this can be an IP address (specified
-as dotted quad or as a Fully Qualified Domain Name, which will be resolved
-immediately) or as a Fully Qualified Domain Name itself (prefixed by ``@''
-to signify that it should not be resolved), or as user@FQDN, or as the
-magic value \fB%myid\fP.
-\fBPluto\fP only authenticates the identity, and does not use it for
-addressing, so, for example, an IP address need not be the one to which
-packets are to be sent. If the option is absent, the
-identity defaults to the IP address specified by \fB\-\-host\fP.
-\fB%myid\fP allows the identity to be separately specified (by the \fBpluto\fP or \fBwhack\fP option \fB\-\-myid\fP
-or by the \fBipsec.conf\fP(5) \fBconfig setup\fP parameter \fPmyid\fP).
-Otherwise, \fBpluto\fP tries to guess what \fB%myid\fP should stand for:
-the IP address of \fB%defaultroute\fP, if it is supported by a suitable TXT record in the reverse domain for that IP address,
-or the system's hostname, if it is supported by a suitable TXT record in its forward domain.
-.\" The identity is transmitted in the IKE protocol, and is what is authenticated.
-.TP
-\fB\-\-host\fP\ \fIip\(hyaddress\fP
-.TP
-\fB\-\-host\fP\ \fB%any\fP
-.TP
-\fB\-\-host\fP\ \fB%opportunistic\fP
-the IP address of the end (generally the public interface).
-If \fBpluto\fP is to act as a responder
-for IKE negotiations initiated from unknown IP addresses (the
-``Road Warrior'' case), the
-IP address should be specified as \fB%any\fP (currently,
-the obsolete notation \fB0.0.0.0\fP is also accepted for this).
-If \fBpluto\fP is to opportunistically initiate the connection,
-use \fB%opportunistic\fP
-.TP
-\fB\-\-ikeport\fP\ \fIport\(hynumber\fP
-the UDP port that IKE listens to on that host. The default is 500.
-(\fBpluto\fP on this machine uses the port specified by its own command
-line argument, so this only affects where \fBpluto\fP sends messages.)
-.TP
-\fB\-\-nexthop\fP\ \fIip\(hyaddress\fP
-where to route packets for the peer's client (presumably for the peer too,
-but it will not be used for this).
-When \fBpluto\fP installs an IPsec SA, it issues a route command.
-It uses the nexthop as the gateway.
-The default is the peer's IP address (this can be explicitly written as
-\fB%direct\fP; the obsolete notation \fB0.0.0.0\fP is accepted).
-This option is necessary if \fBpluto\fP's host's interface used for sending
-packets to the peer is neither point-to-point nor directly connected to the
-peer.
-.TP
-\fB\-\-client\fP\ \fIsubnet\fP
-the subnet for which the IPsec traffic will be destined. If not specified,
-the host will be the client.
-The subnet can be specified in any of the forms supported by \fIipsec_atosubnet\fP(3).
-The general form is \fIaddress\fP/\fImask\fP. The \fIaddress\fP can be either
-a domain name or four decimal numbers (specifying octets) separated by dots.
-The most convenient form of the \fImask\fP is a decimal integer, specifying
-the number of leading one bits in the mask. So, for example, 10.0.0.0/8
-would specify the class A network ``Net 10''.
-.TP
-\fB\-\-dnskeyondemand]\fP
-specifies that when an RSA public key is needed to authenticate this
-host, and it isn't already known, fetch it from DNS.
-.TP
-\fB\-\-updown\fP\ \fIupdown\fP
-specifies an external shell command to be run whenever \fBpluto\fP
-brings up or down a connection.
-The script is used to build a shell command, so it may contain positional
-parameters, but ought not to have punctuation that would cause the
-resulting command to be ill-formed.
-The default is \fIipsec _updown\fP.
-.TP
-\fB\-\-to\fP
-separates the specification of the left and right ends of the connection.
-.LP
-The potential connection description also specifies characteristics of
-rekeying and security.
-.TP
-\fB\-\-psk\fP
-Propose and allow preshared secret authentication for IKE peers. This authentication
-requires that each side use the same secret. May be combined with \fB\-\-rsasig\fP;
-at least one must be specified.
-.TP
-\fB\-\-rsasig\fP
-Propose and allow RSA signatures for authentication of IKE peers. This authentication
-requires that each side have have a private key of its own and know the
-public key of its peer. May be combined with \fB\-\-psk\fP;
-at least one must be specified.
-.TP
-\fB\-\-encrypt\fP
-All proposed or accepted IPsec SAs will include non-null ESP.
-The actual choices of transforms are wired into \fBpluto\fP.
-.TP
-\fB\-\-authenticate\fP
-All proposed IPsec SAs will include AH.
-All accepted IPsec SAs will include AH or ESP with authentication.
-The actual choices of transforms are wired into \fBpluto\fP.
-Note that this has nothing to do with IKE authentication.
-.TP
-\fB\-\-compress\fP
-All proposed IPsec SAs will include IPCOMP (compression).
-This will be ignored if KLIPS is not configured with IPCOMP support.
-.TP
-\fB\-\-tunnel\fP
-the IPsec SA should use tunneling. Implicit if the SA is for clients.
-Must only be used with \fB\-\-authenticate\fP or \fB\-\-encrypt\fP.
-.TP
-\fB\-\-ipv4\fP
-The host addresses will be interpreted as IPv4 addresses. This is the
-default. Note that for a connection, all host addresses must be of
-the same Address Family (IPv4 and IPv6 use different Address Families).
-.TP
-\fB\-\-ipv6\fP
-The host addresses (including nexthop) will be interpreted as IPv6 addresses.
-Note that for a connection, all host addresses must be of
-the same Address Family (IPv4 and IPv6 use different Address Families).
-.TP
-\fB\-\-tunnelipv4\fP
-The client addresses will be interpreted as IPv4 addresses. The default is
-to match what the host will be. This does not imply \fB\-\-tunnel\fP so the
-flag can be safely used when no tunnel is actually specified.
-Note that for a connection, all tunnel addresses must be of the same
-Address Family.
-.TP
-\fB\-\-tunnelipv6\fP
-The client addresses will be interpreted as IPv6 addresses. The default is
-to match what the host will be. This does not imply \fB\-\-tunnel\fP so the
-flag can be safely used when no tunnel is actually specified.
-Note that for a connection, all tunnel addresses must be of the same
-Address Family.
-.TP
-\fB\-\-pfs\fP
-There should be Perfect Forward Secrecy \- new keying material will
-be generated for each IPsec SA rather than being derived from the ISAKMP
-SA keying material.
-Since the group to be used cannot be negotiated (a dubious feature of the
-standard), \fBpluto\fP will propose the same group that was used during Phase 1.
-We don't implement a stronger form of PFS which would require that the
-ISAKMP SA be deleted after the IPSEC SA is negotiated.
-.TP
-\fB\-\-disablearrivalcheck\fP
-If the connection is a tunnel, allow packets arriving through the tunnel
-to have any source and destination addresses.
-.LP
-If none of the \fB\-\-encrypt\fP, \fB\-\-authenticate\fP, \fB\-\-compress\fP,
-or \fB\-\-pfs\fP flags is given, the initiating the connection will
-only build an ISAKMP SA. For such a connection, client subnets have
-no meaning and must not be specified.
-.LP
-More work is needed to allow for flexible policies. Currently
-policy is hardwired in the source file spdb.c. The ISAKMP SAs may use
-Oakley groups MODP1024 and MODP1536; 3DES encryption; SHA1-96
-and MD5-96 authentication. The IPsec SAs may use 3DES and
-MD5-96 or SHA1-96 for ESP, or just MD5-96 or SHA1-96 for AH.
-IPCOMP Compression is always Deflate.
-.TP
-\fB\-\-ikelifetime\fP\ \fIseconds\fP
-how long \fBpluto\fP will propose that an ISAKMP SA be allowed to live.
-The default is 10800 (three hours) and the maximum is 86400 (one day).
-This option will not affect what is accepted.
-\fBpluto\fP will reject proposals that exceed the maximum.
-.TP
-\fB\-\-ipseclifetime\fP\ \fIseconds\fP
-how long \fBpluto\fP will propose that an IPsec SA be allowed to live.
-The default is 3600 (one hour) and the maximum is 86400 (one day).
-This option will not affect what is accepted.
-\fBpluto\fP will reject proposals that exceed the maximum.
-.TP
-\fB\-\-rekeymargin\fP\ \fIseconds\fP
-how long before an SA's expiration should \fBpluto\fP try to negotiate
-a replacement SA. This will only happen if \fBpluto\fP was the initiator.
-The default is 540 (nine minutes).
-.TP
-\fB\-\-rekeyfuzz\fP\ \fIpercentage\fP
-maximum size of random component to add to rekeymargin, expressed as
-a percentage of rekeymargin. \fBpluto\fP will select a delay uniformly
-distributed within this range. By default, the percentage will be 100.
-If greater determinism is desired, specify 0. It may be appropriate
-for the percentage to be much larger than 100.
-.TP
-\fB\-\-keyingtries\fP\ \fIcount\fP
-how many times \fBpluto\fP should try to negotiate an SA,
-either for the first time or for rekeying.
-A value of 0 is interpreted as a very large number: never give up.
-The default is three.
-.TP
-\fB\-\-dontrekey\fP
-A misnomer.
-Only rekey a connection if we were the Initiator and there was recent
-traffic on the existing connection.
-This applies to Phase 1 and Phase 2.
-This is currently the only automatic way for a connection to terminate.
-It may be useful with Road Warrior or Opportunistic connections.
-.br
-Since SA lifetime negotiation is take-it-or-leave it, a Responder
-normally uses the shorter of the negotiated or the configured lifetime.
-This only works because if the lifetime is shorter than negotiated,
-the Responder will rekey in time so that everything works.
-This interacts badly with \fB\-\-dontrekey\fP. In this case,
-the Responder will end up rekeying to rectify a shortfall in an IPsec SA
-lifetime; for an ISAKMP SA, the Responder will accept the negotiated
-lifetime.
-.TP
-\fB\-\-delete\fP
-when used in the connection form, it causes any previous connection
-with this name to be deleted before this one is added. Unlike a
-normal delete, no diagnostic is produced if there was no previous
-connection to delete. Any routing in place for the connection is undone.
-.LP
-The delete form deletes a named connection description and any
-SAs established or negotiations initiated using this connection.
-Any routing in place for the connection is undone.
-.TP
-\fB\-\-delete\fP
-.TP
-\fB\-\-name\fP\ \fIconnection-name\fP
-.LP
-The deletestate form deletes the state object with the specified serial number.

-.LP
-It would be normal to start \fBpluto\fP in one of the system initialization

-To run in manually, the superuser can simply type
-
-\ \ \ ipsec pluto
-
-The command will immediately return, but a \fBpluto\fP process will be left
-running, waiting for requests from \fBwhack\fP or a peer.
-.LP
-Using \fBwhack\fP, several potential connections would be described:
-.HP
-.na
-\ \ \ ipsec whack \-\-name\ silly
-\-\-host\ 127.0.0.1 \-\-to \-\-host\ 127.0.0.2
-\-\-ikelifetime\ 900 \-\-ipseclifetime\ 800 \-\-keyingtries\ 3

-.LP
-Since this silly connection description specifies neither encryption,
-authentication, nor tunneling, it could only be used to establish
-an ISAKMP SA.
-.HP
-.na
-\ \ \ ipsec whack \-\-name\ secret \-\-host\ 10.0.0.1 \-\-client\ 10.0.1.0/24
-\-\-to \-\-host\ 10.0.0.2 \-\-client\ 10.0.2.0/24
-\-\-encrypt
-.ad
-.LP
-This is something that must be done on both sides. If the other
-side is \fBpluto\fP, the same \fBwhack\fP command could be used on it
-(the command syntax is designed to not distinguish which end is ours).
-.LP
-Now that the connections are specified, \fBpluto\fP is ready to handle
-requests and replies via the public interfaces. We must tell it to discover
-those interfaces and start accepting messages from peers:
-
-\ \ \ ipsec whack \-\-listen
-.LP
-If we don't immediately wish to bring up a secure connection between
-the two clients, we might wish to prevent insecure traffic.
-The routing form asks \fBpluto\fP to cause the packets sent from
-our client to the peer's client to be routed through the ipsec0
-device; if there is no SA, they will be discarded:
-
-\ \ \ ipsec whack \-\-route secret
-.LP
-Finally, we are ready to get \fBpluto\fP to initiate negotiation
-for an IPsec SA (and implicitly, an ISAKMP SA):
-
-\ \ \ ipsec whack \-\-initiate\ \-\-name\ secret
-
-A small log of interesting events will appear on standard output
-(other logging is sent to syslog).
-.LP
-\fBwhack\fP can also be used to terminate \fBpluto\fP cleanly, tearing down
-all SAs that it has negotiated.
-
-\ \ \ ipsec whack \-\-shutdown
-
-Notification of any IPSEC SA deletion, but not ISAKMP SA deletion
-is sent to the peer. Unfortunately, such Notification is not reliable.
-Furthermore, \fBpluto\fP itself ignores Notifications.
-.SS The updown command
-.LP
-Whenever \fBpluto\fP brings a connection up or down, it invokes
-the updown command. This command is specified using the \fB\-\-updown\fP
-option. This allows for customized control over routing and firewall manipulation.
-.LP
-The updown is invoked for five different operations. Each of
-these operations can be for our client subnet or for our host itself.
-.TP
-\fBprepare-host\fP or \fBprepare-client\fP
-is run before bringing up a new connection if no other connection
-with the same clients is up. Generally, this is useful for deleting a
-route that might have been set up before \fBpluto\fP was run or
-perhaps by some agent not known to \fBpluto\fP.
-.TP
-\fBroute-host\fP or \fBroute-client\fP
-is run when bringing up a connection for a new peer client subnet
-(even if \fBprepare-host\fP or \fBprepare-client\fP was run). The
-command should install a suitable route. Routing decisions are based
-only on the destination (peer's client) subnet address, unlike eroutes
-which discriminate based on source too.
-.TP
-\fBunroute-host\fP or \fBunroute-client\fP
-is run when bringing down the last connection for a particular peer
-client subnet. It should undo what the \fBroute-host\fP or \fBroute-client\fP
-did.
-.TP
-\fBup-host\fP or \fBup-client\fP
-is run when bringing up a tunnel eroute with a pair of client subnets
-that does not already have a tunnel eroute.
-This command should install firewall rules as appropriate.
-It is generally a good idea to allow IKE messages (UDP port 500)
-travel between the hosts.
-.TP
-\fBdown-host\fP or \fBdown-client\fP
-is run when bringing down the eroute for a pair of client subnets.
-This command should delete firewall rules as appropriate. Note that
-there may remain some inbound IPsec SAs with these client subnets.
-.LP
-The script is passed a large number of environment variables to specify
-what needs to be done.
-.TP
-\fBPLUTO_VERSION\fP
-indicates what version of this interface is being used. This document
-describes version 1.1. This is upwardly compatible with version 1.0.
-.TP
-\fBPLUTO_VERB\fP
-specifies the name of the operation to be performed
-(\fBprepare-host\fP,r \fBprepare-client\fP,
-\fBup-host\fP, \fBup-client\fP,
-\fBdown-host\fP, or \fBdown-client\fP). If the address family for
-security gateway to security gateway communications is IPv6, then
-a suffix of -v6 is added to the verb.
-.TP
-\fBPLUTO_CONNECTION\fP
-is the name of the connection for which we are routing.
-.TP
-\fBPLUTO_NEXT_HOP\fP
-is the next hop to which packets bound for the peer must be sent.

-\fBPLUTO_INTERFACE\fP
-is the name of the ipsec interface to be used.

-\fBPLUTO_ME\fP
-is the IP address of our host.
-.TP
-\fBPLUTO_MY_CLIENT\fP
-is the IP address / count of our client subnet.
-If the client is just the host, this will be the host's own IP address / max
-(where max is 32 for IPv4 and 128 for IPv6).
-.TP
-\fBPLUTO_MY_CLIENT_NET\fP
-is the IP address of our client net.
-If the client is just the host, this will be the host's own IP address.
-.TP
-\fBPLUTO_MY_CLIENT_MASK\fP
-is the mask for our client net.
-If the client is just the host, this will be 255.255.255.255.
-.TP
-\fBPLUTO_PEER\fP
-is the IP address of our peer.
-.TP
-\fBPLUTO_PEER_CLIENT\fP
-is the IP address / count of the peer's client subnet.
-If the client is just the peer, this will be the peer's own IP address / max
-(where max is 32 for IPv4 and 128 for IPv6).
-.TP
-\fBPLUTO_PEER_CLIENT_NET\fP
-is the IP address of the peer's client net.
-If the client is just the peer, this will be the peer's own IP address.
-.TP
-\fBPLUTO_PEER_CLIENT_MASK\fP
-is the mask for the peer's client net.
-If the client is just the peer, this will be 255.255.255.255.
-.LP
-All output sent by the script to stderr or stdout is logged. The
-script should return an exit status of 0 if and only if it succeeds.
-.LP
-\fBPluto\fP waits for the script to finish and will not do any other
-processing while it is waiting.
-The script may assume that \fBpluto\fP will not change anything
-while the script runs.
-The script should avoid doing anything that takes much time and it
-should not issue any command that requires processing by \fBpluto\fP.
-Either of these activities could be performed by a background
-subprocess of the script.
-.SS Rekeying
-.LP
-When an SA that was initiated by \fBpluto\fP has only a bit of
-lifetime left,
-\fBpluto\fP will initiate the creation of a new SA. This applies to
-ISAKMP and IPsec SAs.
-The rekeying will be initiated when the SA's remaining lifetime is
-less than the rekeymargin plus a random percentage, between 0 and
-rekeyfuzz, of the rekeymargin.
-.LP
-Similarly, when an SA that was initiated by the peer has only a bit of
-lifetime left, \fBpluto\fP will try to initiate the creation of a
-replacement.
-To give preference to the initiator, this rekeying will only be initiated
-when the SA's remaining lifetime is half of rekeymargin.
-If rekeying is done by the responder, the roles will be reversed: the
-responder for the old SA will be the initiator for the replacement.
-The former initiator might also initiate rekeying, so there may
-be redundant SAs created.
-To avoid these complications, make sure that rekeymargin is generous.
-.LP
-One risk of having the former responder initiate is that perhaps
-none of its proposals is acceptable to the former initiator
-(they have not been used in a successful negotiation).
-To reduce the chances of this happening, and to prevent loss of security,
-the policy settings are taken from the old SA (this is the case even if
-the former initiator is initiating).
-These may be stricter than those of the connection.
-.LP
-\fBpluto\fP will not rekey an SA if that SA is not the most recent of its
-type (IPsec or ISAKMP) for its potential connection.
-This avoids creating redundant SAs.
-.LP
-The random component in the rekeying time (rekeyfuzz) is intended to
-make certain pathological patterns of rekeying unstable. If both
-sides decide to rekey at the same time, twice as many SAs as necessary
-are created. This could become a stable pattern without the
-randomness.
-.LP
-Another more important case occurs when a security gateway has SAs
-with many other security gateways. Each of these connections might
-need to be rekeyed at the same time. This would cause a high peek
-requirement for resources (network bandwidth, CPU time, entropy for
-random numbers). The rekeyfuzz can be used to stagger the rekeying
-times.
-.LP
-Once a new set of SAs has been negotiated, \fBpluto\fP will never send
-traffic on a superseded one. Traffic will be accepted on an old SA
-until it expires.
-.SS Selecting a Connection When Responding: Road Warrior Support
-.LP
-When \fBpluto\fP receives an initial Main Mode message, it needs to
-decide which connection this message is for. It picks based solely on
-the source and destination IP addresses of the message. There might
-be several connections with suitable IP addresses, in which case one
-of them is arbitrarily chosen. (The ISAKMP SA proposal contained in
-the message could be taken into account, but it is not.)
-.LP
-The ISAKMP SA is negotiated before the parties pass further
-identifying information, so all ISAKMP SA characteristics specified in
-the connection description should be the same for every connection
-with the same two host IP addresses. At the moment, the only
-characteristic that might differ is authentication method.
-.LP
-Up to this point,
-all configuring has presumed that the IP addresses
-are known to all parties ahead of time. This will not work
-when either end is mobile (or assigned a dynamic IP address for other
-reasons). We call this situation ``Road Warrior''. It is fairly tricky
-and has some important limitations, most of which are features of
-the IKE protocol.
-.LP
-Only the initiator may be mobile:
-the initiator may have an IP number unknown to the responder. When
-the responder doesn't recognize the IP address on the first Main Mode
-packet, it looks for a connection with itself as one end and \fB%any\fP
-as the other.
-If it cannot find one, it refuses to negotiate. If it
-does find one, it creates a temporary connection that is a duplicate
-except with the \fB%any\fP replaced by the source IP address from the
-packet; if there was no identity specified for the peer, the new IP
-address will be used.
-.LP
-When \fBpluto\fP is using one of these temporary connections and
-needs to find the preshared secret or RSA private key in \fIipsec.secrets\fP,
-and and the connection specified no identity for the peer, \fB%any\fP
-is used as its identity. After all, the real IP address was apparently
-unknown to the configuration, so it is unreasonable to require that
-it be used in this table.
-.LP
-Part way into the Phase 1 (Main Mode) negotiation using one of these
-temporary connection descriptions, \fBpluto\fP will be receive an
-Identity Payload. At this point, \fBpluto\fP checks for a more
-appropriate connection, one with an identity for the peer that matches
-the payload but which would use the same keys so-far used for
-authentication. If it finds one, it will switch to using this better
-connection (or a temporary derived from this, if it has \fB%any\fP
-for the peer's IP address). It may even turn out that no connection
-matches the newly discovered identity, including the current connection;
-if so, \fBpluto\fP terminates negotiation.
-.LP
-Unfortunately, if preshared secret authentication is being used, the
-Identity Payload is encrypted using this secret, so the secret must be
-selected by the responder without knowing this payload. This
-limits there to being at most one preshared secret for all Road Warrior
-systems connecting to a host. RSA Signature authentications does not
-require that the responder know how to select the initiator's public key
-until after the initiator's Identity Payload is decoded (using the
-responder's private key, so that must be preselected).
-.LP
-When \fBpluto\fP is responding to a Quick Mode negotiation via one of these
-temporary connection descriptions, it may well find that the subnets
-specified by the initiator don't match those in the temporary
-connection description. If so, it will look for a connection with
-matching subnets, its own host address, a peer address of \fB%any\fP
-and matching identities.
-If it finds one, a new temporary connection is derived from this one
-and used for the Quick Mode negotiation of IPsec SAs. If it does not
-find one, \fBpluto\fP terminates negotiation.
-.LP
-Be sure to specify an appropriate nexthop for the responder
-to send a message to the initiator: \fBpluto\fP has no way of guessing
-it (if forwarding isn't required, use an explicit \fB%direct\fP as the nexthop
-and the IP address of the initiator will be filled in; the obsolete
-notation \fB0.0.0.0\fP is still accepted).
-.LP
-\fBpluto\fP has no special provision for the initiator side. The current
-(possibly dynamic) IP address and nexthop must be used in defining
-connections. These must be
-properly configured each time the initiator's IP address changes.
-\fBpluto\fP has no mechanism to do this automatically.
-.LP
-Although we call this Road Warrior Support, it could also be used to
-support encrypted connections with anonymous initiators. The
-responder's organization could announce the preshared secret that would be used
-with unrecognized initiators and let anyone connect. Of course the initiator's
-identity would not be authenticated.
-.LP
-If any Road Warrior connections are supported, \fBpluto\fP cannot
-reject an exchange initiated by an unknown host until it has
-determined that the secret is not shared or the signature is invalid.
-This must await the
-third Main Mode message from the initiator. If no Road Warrior
-connection is supported, the first message from an unknown source
-would be rejected. This has implications for ease of debugging
-configurations and for denial of service attacks.
-.LP
-Although a Road Warrior connection must be initiated by the mobile
-side, the other side can and will rekey using the temporary connection
-it has created. If the Road Warrior wishes to be able to disconnect,
-it is probably wise to set \fB\-\-keyingtries\fP to 1 in the
-connection on the non-mobile side to prevent it trying to rekey the
-connection. Unfortunately, there is no mechanism to unroute the
-connection automatically.
-.SS Debugging
-.LP
-\fBpluto\fP accepts several optional arguments, useful mostly for debugging.
-Except for \fB\-\-interface\fP, each should appear at most once.
-.TP
-\fB\-\-interface\fP \fIinterfacename\fP
-specifies that the named real public network interface should be considered.
-The interface name specified should not be \fBipsec\fP\fIN\fP.
-If the option doesn't appear, all interfaces are considered.
-To specify several interfaces, use the option once for each.
-One use of this option is to specify which interface should be used
-when two or more share the same IP address.
-.TP
-\fB\-\-ikeport\fP \fIport-number\fP
-changes the UDP port that \fBpluto\fP will use
-(default, specified by IANA: 500)
-.TP
-\fB\-\-ctlbase\fP \fIpath\fP
-basename for control files.
-\fIpath\fP.ctl is the socket through which \fBwhack\fP communicates with
-\fBpluto\fP.
-\fIpath\fP.pid is the lockfile to prevent multiple \fBpluto\fP instances.
-The default is \fI/var/run/pluto\fP).
-.TP
-\fB\-\-secretsfile\fP \fIfile\fP
-specifies the file for authentication secrets
-(default: \fI/etc/ipsec.secrets\fP).
-This name is subject to ``globbing'' as in \fIsh\fP(1),
-so every file with a matching name is processed.
-Quoting is generally needed to prevent the shell from doing the globbing.
-.TP
-\fB\-\-adns\fP \fIpathname\fP
-.TP
-\fB\-\-lwdnsq\fP \fIpathname\fP
-specifies where to find \fBpluto\fP's helper program for asynchronous DNS lookup.
-\fBpluto\fP can be built to use one of two helper programs: \fB_pluto_adns\fP
-or \fBlwdnsq\fP. You must use the program for which it was built.
-By default, \fBpluto\fP will look for the program in
-\fB$IPSEC_DIR\fP (if that environment variable is defined) or, failing that,
-in the same directory as \fBpluto\fP.
-.TP
-\fB\-\-nofork\fP
-disable ``daemon fork'' (default is to fork). In addition, after the
-lock file and control socket are created, print the line ``Pluto
-initialized'' to standard out.
-.TP
-\fB\-\-noklips\fP
-don't actually implement negotiated IPsec SAs
-.TP
-\fB\-\-uniqueids\fP
-if this option has been selected, whenever a new ISAKMP SA is
-established, any connection with the same Peer ID but a different
-Peer IP address is unoriented (causing all its SAs to be deleted).
-This helps clean up dangling SAs when a connection is lost and
-then regained at another IP address.
-.TP
-\fB\-\-stderrlog\fP
-log goes to standard out {default is to use \fIsyslogd\fP(8))
-.LP
-For example
-.TP
-pluto \-\-secretsfile\ ipsec.secrets \-\-ctlbase\ pluto.base \-\-ikeport\ 8500 \-\-nofork \-\-noklips \-\-stderrlog
-.LP
-lets one test \fBpluto\fP without using the superuser account.
-.LP
-\fBpluto\fP is willing to produce a prodigious amount of debugging
-information. To do so, it must be compiled with \-DDEBUG. There are
-several classes of debugging output, and \fBpluto\fP may be directed to
-produce a selection of them. All lines of
-debugging output are prefixed with ``|\ '' to distinguish them from error
-messages.
-.LP
-When \fBpluto\fP is invoked, it may be given arguments to specify
-which classes to output. The current options are:
-.TP
-\fB\-\-debug-raw\fP
-show the raw bytes of messages
-.TP
-\fB\-\-debug-crypt\fP
-show the encryption and decryption of messages
-.TP
-\fB\-\-debug-parsing\fP
-show the structure of input messages
-.TP
-\fB\-\-debug-emitting\fP
-show the structure of output messages
-.TP
-\fB\-\-debug-control\fP
-show \fBpluto\fP's decision making
-.TP
-\fB\-\-debug-lifecycle\fP
-[this option is temporary] log more detail of lifecycle of SAs
-.TP
-\fB\-\-debug-klips\fP
-show \fBpluto\fP's interaction with \fBKLIPS\fP
-.TP
-\fB\-\-debug-dns\fP
-show \fBpluto\fP's interaction with \fBDNS\fP for KEY and TXT records
-.TP
-\fB\-\-debug-oppo\fP
-show why \fBpluto\fP didn't find a suitable DNS TXT record to authorize opportunistic initiation
-.TP
-\fB\-\-debug-all\fP
-all of the above
-.TP
-\fB\-\-debug-private\fP
-allow debugging output with private keys.
-.TP
-\fB\-\-debug-none\fP
-none of the above
-.LP
-The debug form of the
-\fBwhack\fP command will change the selection in a running
-\fBpluto\fP.
-If a connection name is specified, the flags are added whenever
-\fBpluto\fP has identified that it is dealing with that connection.
-Unfortunately, this is often part way into the operation being observed.
-.LP
-For example, to start a \fBpluto\fP with a display of the structure of input
-and output:
-.IP
-pluto \-\-debug-emitting \-\-debug-parsing
-.LP
-To later change this \fBpluto\fP to only display raw bytes:
-.IP
-whack \-\-debug-raw
-.LP
-For testing, SSH's IKE test page is quite useful:
-.IP
-\fIhttp://isakmp-test.ssh.fi/\fP
-.LP
-Hint: ISAKMP SAs are often kept alive by IKEs even after the IPsec SA
-is established. This allows future IPsec SA's to be negotiated
-directly. If one of the IKEs is restarted, the other may try to use
-the ISAKMP SA but the new IKE won't know about it. This can lead to
-much confusion. \fBpluto\fP is not yet smart enough to get out of such a
-mess.
-.SS Pluto's Behaviour When Things Go Wrong
-.LP
-When \fBpluto\fP doesn't understand or accept a message, it just
-ignores the message. It is not yet capable of communicating the
-problem to the other IKE daemon (in the future it might use
-Notifications to accomplish this in many cases). It does log a diagnostic.
-.LP
-When \fBpluto\fP gets no response from a message, it resends the same
-message (a message will be sent at most three times). This is
-appropriate: UDP is unreliable.
-.LP
-When pluto gets a message that it has already seen, there are many
-cases when it notices and discards it. This too is appropriate for UDP.
-.LP
-Combine these three rules, and you can explain many apparently
-mysterious behaviours. In a \fBpluto\fP log, retrying isn't usually the
-interesting event. The critical thing is either earlier (\fBpluto\fP
-got a message which it didn't like and so ignored, so it was still
-awaiting an acceptable message and got impatient) or on the other
-system (\fBpluto\fP didn't send a reply because it wasn't happy with
-the previous message).
-.SS Notes
-.LP
-If \fBpluto\fP is compiled without \-DKLIPS, it negotiates Security
-Associations but never ask the kernel to put them in place and never
-makes routing changes. This allows \fBpluto\fP to be tested on systems
-without \fBKLIPS\fP, but makes it rather useless.
-.LP
-Each IPsec SA is assigned an SPI, a 32-bit number used to refer to the SA.
-The IKE protocol lets the destination of the SA choose the SPI.
-The range 0 to 0xFF is reserved for IANA.
-\fBPluto\fP also avoids choosing an SPI in the range 0x100 to 0xFFF,
-leaving these SPIs free for manual keying.
-Remember that the peer, if not \fBpluto\fP, may well chose
-SPIs in this range.
-.SS Policies
-.LP
-This catalogue of policies may be of use when trying to configure
-\fBPluto\fP and another IKE implementation to interoperate.
-.LP
-In Phase 1, only Main Mode is supported. We are not sure that
-Aggressive Mode is secure. For one thing, it does not support
-identity protection. It may allow more severe Denial Of Service
-attacks.
-.LP
-No Informational Exchanges are supported. These are optional and
-since their delivery is not assured, they must not matter.
-It is the case that some IKE implementations won't interoperate
-without Informational Exchanges, but we feel they are broken.
-.LP
-No Informational Payloads are supported. These are optional, but
-useful. It is of concern that these payloads are not authenticated in
-Phase 1, nor in those Phase 2 messages authenticated with HASH(3).
-.IP \(bu \w'\(bu\ 'u
-Diffie Hellman Groups MODP 1024 and MODP 1536 (2 and 5)
-are supported.
-Group MODP768 (1) is not supported because it is too weak.
-.IP \(bu
-Host authetication can be done by RSA Signatures or Pre-Shared
-Secrets.
-.IP \(bu
-3DES CBC (Cypher Block Chaining mode) is the only encryption
-supported, both for ISAKMP SAs and IPSEC SAs.
-.IP \(bu
-MD5 and SHA1 hashing are supported for packet authentication in both
-kinds of SAs.
-.IP \(bu
-The ESP, AH, or AH plus ESP are supported. If, and only if, AH and
-ESP are combined, the ESP need not have its own authentication
-component. The selection is controlled by the \-\-encrypt and
-\-\-authenticate flags.
-.IP \(bu
-Each of these may be combined with IPCOMP Deflate compression,
-but only if the potential connection specifies compression and only
-if KLIPS is configured with IPCOMP support.
-.IP \(bu
-The IPSEC SAs may be tunnel or transport mode, where appropriate.
-The \-\-tunnel flag controls this when \fBpluto\fP is initiating.
-.IP \(bu
-When responding to an ISAKMP SA proposal, the maximum acceptable
-lifetime is eight hours. The default is one hour. There is no
-minimum. The \-\-ikelifetime flag controls this when \fBpluto\fP
-is initiating.
-.IP \(bu
-When responding to an IPSEC SA proposal, the maximum acceptable
-lifetime is one day. The default is eight hours. There is no
-minimum. The \-\-ipseclifetime flag controls this when \fBpluto\fP
-is initiating.
-.IP \(bu
-PFS is acceptable, and will be proposed if the \-\-pfs flag was
-specified. The DH group proposed will be the same as negotiated for
-Phase 1.
-.SH SIGNALS
-.LP
-\fBPluto\fP responds to \fBSIGHUP\fP by issuing a suggestion that ``\fBwhack\fP
-\-\-listen'' might have been intended.
-.LP
-\fBPluto\fP exits when it recieves \fBSIGTERM\fP.
-.SH EXIT STATUS
-.LP
-\fBpluto\fP normally forks a daemon process, so the exit status is
-normally a very preliminary result.
-.TP
-0
-means that all is OK so far.
-.TP
-1
-means that something was wrong.
-.TP
-10
-means that the lock file already exists.
-.LP
-If \fBwhack\fP detects a problem, it will return an exit status of 1.
-If it received progress messages from \fBpluto\fP, it returns as status
-the value of the numeric prefix from the last such message
-that was not a message sent to syslog or a comment
-(but the prefix for success is treated as 0).
-Otherwise, the exit status is 0.

-.SH HISTORY
-This code is released under the GPL terms.
-See the accompanying file COPYING-2.0 for more details.
-The GPL does NOT apply to those pieces of code written by others
-which are included in this distribution, except as noted by the
-individual authors.
-.LP
-This software was originally written
-for the FreeS/WAN project
-<http://www.freeswan.org>
-by Angelos D. Keromytis
-(angelos@dsl.cis.upenn.edu), in May/June 1997, in Athens, Greece.
-Thanks go to John Ioannidis for his help.
-.LP
-It is currently (2000)
-being developed and maintained by D. Hugh Redelmeier
-(hugh@mimosa.com), in Canada. The regulations of Greece and Canada
-allow us to make the code freely redistributable.
-.LP
-Kai Martius (admin@imib.med.tu-dresden.de) contributed the initial
-version of the code supporting PFS.
-.LP
-Richard Guy Briggs <rgb@conscoop.ottawa.on.ca> and Peter Onion
-<ponion@srd.bt.co.uk> added the PFKEY2 support.
-.LP
-We gratefully acknowledge that we use parts of Eric Young's \fIlibdes\fP
-package; see \fI../libdes/COPYRIGHT\fP.
-.SH BUGS
-.BR pluto
-is a work-in-progress. It currently has many limitations.
-For example, it ignores notification messages that it receives, and
-it generates only Delete Notifications and those only for IPSEC SAs.
-.LP
-\fBpluto\fP does not support the Commit Flag.
-The Commit Flag is a bad feature of the IKE protocol.
-It isn't protected -- neither encrypted nor authenticated.
-A man in the middle could turn it on, leading to DoS.
-We just ignore it, with a warning.
-This should let us interoperate with
-implementations that insist on it, with minor damage.
-.LP
-\fBpluto\fP does not check that the SA returned by the Responder
-is actually one that was proposed. It only checks that the SA is
-acceptable. The difference is not large, but can show up in attributes
-such as SA lifetime.
-.LP
-There is no good way for a connection to be automatically terminated.
-This is a problem for Road Warrior and Opportunistic connections.
-The \fB\-\-dontrekey\fP option does prevent the SAs from
-being rekeyed on expiry.
-Additonally, if a Road Warrior connection has a client subnet with a fixed IP
-address, a negotiation with that subnet will cause any other
-connection instantiations with that same subnet to be unoriented
-(deleted, in effect).
-See also the \-\-uniqueids option for an extension of this.
-.LP
-When \fBpluto\fP sends a message to a peer that has disappeared,
-\fBpluto\fP receives incomplete information from the kernel, so it
-logs the unsatisfactory message ``some IKE message we sent has been
-rejected with ECONNREFUSED (kernel supplied no details)''. John
-Denker suggests that this command is useful for tracking down the
-source of these problems:
-.br
- tcpdump -i eth0 icmp[0] != 8 and icmp[0] != 0
-.br
-Substitute your public interface for eth0 if it is different.
-.LP
-The word ``authenticate'' is used for two different features. We must
-authenticate each IKE peer to the other. This is an important task of
-Phase 1. Each packet must be authenticated, both in IKE and in IPsec,
-and the method for IPsec is negotiated as an AH SA or part of an ESP SA.
-Unfortunately, the protocol has no mechanism for authenticating the Phase 2
-identities.
-.LP
-Bugs should be reported to the <users@lists.freeswan.org> mailing list.
-Caution: we cannot accept
-actual code from US residents, or even US citizens living outside the
-US, because that would bring FreeS/WAN under US export law. Some
-other countries cause similar problems. In general, we would prefer
-that you send detailed problem reports rather than code: we want
-FreeS/WAN to be unquestionably freely exportable, which means being
-very careful about where the code comes from, and for a small bug fix,
-that is often more time-consuming than just reinventing the fix
-ourselves.

-Routing and Erouting in Pluto
-=============================
-
-RCSID $Id: routing.txt,v 1.1 2004/03/15 20:35:29 as Exp $
-
-This is meant as internal documentation for Pluto. As such, it
-presumes some understanding of Pluto's code.
-
-It also describes KLIPS 1 erouting, including details not otherwise
-documented. KLIPS 1 documentation would be better included in KLIPS.
-
-Routing and erouting are complicated enough that the Pluto code needs
-a guide. This document is meant to be that guide.
-
-
-Mechanisms available to Pluto
------------------------------
-
-All outbound packets that are to be processed by KLIPS 1 must be
-routed to an ipsecN network interface. Pluto only uses normal routing
-(as opposed to "Advanced Routing"), so the selection of packets is
-made solely on the basis of the destination address. (Since the
-actual routing commands are in the updown script, they could be
-changed by the administrator, but Pluto needs to understand what is
-going on, and it currently assumes normal routing is used.)
-
-When an outbound packet hits an ipsecN interface, KLIPS figures out
-how to process it by finding an eroute that applies to the source and
-destination addresses. Eroutes are global: they are not specific to a
-particular ipsecN interface (routing needs to get the packets to any
-ipsecN interface; erouting takes it from there, ignoring issues of
-source IP address and nexthop (because nobody knows!)). If multiple
-eroutes apply to the packet, among the ones with the most specific
-source subnet, the one with the most specific destination subset is
-chosen (RGB thinks). If no eroute is discovered, KLIPS acts as if it
-was covered by a DROP eroute (this is the default behaviour; it can be
-changed). At most one eroute can exist for a particular pair of
-client subnets.
-
-There are fundamentally two kinds of eroutes: "shunt" eroutes and ones
-that specify that a packet is to be processed by a group of IPSEC SAs.
-Shunt eroutes specify what is to be done with the packet. Remember
-that these only apply to outbound packets.
-
-- TRAP: notify Pluto of the packet (presumably to attempt to negotiate
- an appropriate group of IPSEC SAs). At the same time, KLIPS
- installs a HOLD shunt (see below) for the specific source and
- destination addresses from the packet and retains the packet
- for later reprocessing (KLIPS does not yet implement retention).
- Beware: if the TRAP's subnets both contained a single IP address
- then installing the HOLD would actually delete the TRAP.
-
-- PASS: let the packet through in the clear
-
-- DROP: discard the packet
-
-- REJECT: discard the packet and notify the sender
-
-- HOLD: (automatically created by KLIPS when a TRAP fires) block
- the packet, but retain it. If there is already a retained
- packet, drop the old one and retain the new. When the HOLD
- shunt is deleted or replaced, the retained packet is reinjected --
- there might now be a tunnel. Note that KLIPS doesn't yet
- implement the retention part, so HOLD is really like a DROP.
-
-One consequence of there being only one eroute for a pair of clients
-is that KLIPS will only use one SA group for output for this pair,
-even though there could be several SA groups that are authorised and
-live. Pluto chooses to make this the youngest such group.
-
-
-
-KLIPS lets through in the clear outbound UDP/500 packets that would
-otherwise be processed if they originate on this host and meet certain
-other conditions. The actual test is
- source == me
- && (no_eroute || dest == eroute.dest || isanyaddr(eroute.dest))
- && port == UDP/500
-The idea is that IKE packets between us and a peer should not be
-sent through an IPSEC tunnel negotiated between us. Furthermore,
-our shunt eroutes should not apply to our IKE packets (shunt eroutes
-will generally have an eroute.dest of 0.0.0.0 or its IPv6 equivalent).
-
-Inbound behaviour is controlled in a quite different way. KLIPS
-processes only those inbound packets of ESP or AH protocol, with a
-destination address for this machine's ipsecN interfaces. The
-processing is as dictated by the SAs involved. Unfortunately, the
-decapsulated packet's source and destination address are not checked
-(part of "inbound policy checking").
-
-To prevent clear packets being accepted, firewall rules must be put in
-place. This has nothing to do with KLIPS, but is nonetheless in
-important part of security. It isn't clear what firewalling makes
-sense when Opportunism is allowed.
-
-
-For routing and firewalling, Pluto invokes the updown script. Pluto
-installs eroutes via extended PF_KEY messages.
-
-
-Current Pluto Behaviour
------------------------
-
-Data Structures:
-
-Routes and most eroutes are associated with connections (struct
-connection, a potential connection description). The enum routing_t
-field "routing" in struct connection records the state of routing and
-erouting for that connection. The values are:
- RT_UNROUTED, /* unrouted */
- RT_UNROUTED_HOLD, /* unrouted, but HOLD shunt installed */
- RT_ROUTED_PROSPECTIVE, /* routed, and TRAP shunt installed */
- RT_ROUTED_HOLD, /* routed, and HOLD shunt installed */
- RT_ROUTED_FAILURE, /* routed, and failure-context shunt installed */
- RT_ROUTED_TUNNEL /* routed, and erouted to an IPSEC SA group */
-Notice that the routing and erouting are not independent: erouting
-(except for HOLD) implies that the connection is routed.
-
-Several struct connections may have the same destination subnet. If
-they agree on what the route should be, they can share it -- any of
-them may have routing >= RT_ROUTED_PROSPECTIVE. If they disagree,
-they cannot simultaneously be routed.
-
-invariant: for all struct connections c, d:
- (c.that.client == d.that.client
- && c.routing >= RT_ROUTED_PROSPECTIVE
- && d.routing >= RT_ROUTED_PROSPECTIVE)
- => c.interface == d.interface && c.this.nexthop == d.this.nexthop
-
-There are two kinds of eroutes: shunt eroutes and ones for an IPSEC SA
-Group. Most eroutes are associated with and are represeented in a
-connection. The exception is that some HOLD and PASS shunts do not
-correspond to connections; those are represented in the bare_shunt
-table.
-
-An eroute for an IPSEC SA Group is associated with the state object
-for that Group. The existence of such an eroute is also represented
-by the "so_serial_t eroute_owner" field in the struct connection. The
-value is the serial number of the state object for the Group. The
-special value SOS_NOBODY means that there is no owner associated with
-this connection for the eroute and hence no normal eroute. At most
-one eroute owner may exist for a particular (source subnet,
-destination subnet) pair. A Pluto-managed eroute cannot be associated
-with an RT_UNROUTED connection.
-
-invariant: for all struct connection c:
- c.routing == RT_EROUTED_TUNNEL || c.eroute_owner == SOS_NOBODY
-
-invariant: for all struct connections c, d:
- c.this.client == d.this.client && c.that.client == d.that.client
- && &c != &d
- => c.routing == RT_UNROUTED || d.routing == RT_UNROUTED
-
-If no normal eroute is set for a particular (source subnet,
-destination subnet) pair for which a connection is routed, then a
-shunt eroute would have been installed. This specifies what should
-happen to packets snared by the route.
-
-When Pluto is notified by KLIPS of a packet that has been TRAPped,
-there is no connection with which to associate the HOLD. It is
-temporarily held in the "bare_shunt table". If Opportunism is
-attempted but DNS doesn't provide Security Gateway information, Pluto
-will replace the HOLD with a PASS shunt. Since this PASS isn't
-associated with a connection, it too will reside in the bare_shunt
-table. If the HOLD can be associated with a connection, it will be
-removed from the bare_shunt table and represented in the connection.
-
-There are two contexts for which shunt eroutes are installed by Pluto
-for a particular connection. The first context is with the prospect
-of dealing with packets before any negotiation has been attempted. I
-call this context "prospective". Currently is a TRAP shunt, used to
-catch packets for initiate opportunistic negotiation. In the future,
-it might also be used to implement preordained PASS, DROP, or REJECT
-rules.
-
-The second context is after a failed negotiation. I call this context
-"failure". At this point a different kind of shunt eroute is
-appropriate. Depending on policy, it could be PASS, DROP, or REJECT,
-but it is unlikely to be TRAP. The shunt eroute should have a
-lifetime (this isn't yet implemented). When the lifetime expires, the
-failure shunt eroute should be replaced by the prospective shunt
-eroute.
-
-The kind and duration of a failure shunt eroute should perhaps depend
-on the nature of the failure, at least as imperfectly detected by
-Pluto. We haven't looked at this. In particular, the mapping from
-observations to robust respose isn't obvious.
-
-The shunt eroute policies should be a function of the potential
-connection. The failure shunt eroute can be specified for a
-particular connection with the flags --pass and --drop in a connection
-definition. There are four combinations, and each has a distinct
-meaning. The failure shunt eroute is incompletely implemented and
-cannot be represented in /etc/ipsec.conf.
-
-There is as yet no control over the prospective shunt eroute: it is
-always TRAP as far as Pluto is concerned. This is probably
-reasonable: any other fate suggests that no negotiation will be done,
-and so a connection definition is inappropriate. These should be
-implemented as manual conns. There remains the issue of whether Pluto
-should be aware of them -- currently it is not.
-
-
-Routines:
-
-[in kernel.c]
-
-bool do_command(struct connection *c, const char *verb)
- Run the updown script to perform such tasks as installing a route
- and adjust the firewall.
-
-bool could_route(struct connection *c)
- Check to see whether we could route and eroute the connection.
- <- shunt_eroute_connection (to check if --route can be performed)
- <- install_inbound_ipsec_sa (to see if it will be possible
- to (later) install route and eroute the corresponding outbound SA)
- <- install_ipsec_sa (to see if the outbound SA can be routed and erouted)
-
-bool trap_connection(struct connection *c)
- Install a TRAP shunt eroute for this connection. This implements
- "whack --route", the way an admin can specify that packets for a
- connection should be caught without first bringing it up.
-
-void unroute_connection(struct connection *c)
- Delete any eroute for a connection and unroute it if route isn't shared.
- <- release_connection
- <- whack_handle (for "whack --unroute)
-
-bool eroute_connection(struct connection *c
-, ipsec_spi_t spi, unsigned int proto, unsigned int satype
-, unsigned int op, const char *opname UNUSED)
- Issue PF_KEY commands to KLIPS to add, replace, or delete an eroute.
- The verb is specified by op and described (for logging) by opname.
- <- assign_hold
- <- sag_eroute
- <- shunt_eroute
-
-bool assign_hold(struct connection *c
-, const ip_address *src, const ip_address *dst)
- Take a HOLD from the bare_shunt table and assign it to a connection.
- If the HOLD is broadened (i.e. the connection's source or destination
- subnets contain more than one IP address), this will involve replacing
- the HOLD with a different one.
-
-bool sag_eroute(struct state *st, unsigned op, const char *opname)
- SA Group eroute manipulation. The SA Group concerned is
- identified with a state object.
- <- route_and_eroute several times
-
-bool shunt_eroute(struct connection *c, unsigned int op, const char *opname)
- shunt eroute manipulation. Shunt eroutes are associated with
- connections.
- <- unroute_connection
- <- route_and_eroute
- <- delete_ipsec_sa
-
-bool route_and_eroute(struct connection *c, struct state *st)
- Install a route and then a prospective shunt eroute or an SA group
- eroute. The code assumes that could_route had previously
- given the go-ahead. Any SA group to be erouted must already
- exist.
- <- shunt_eroute_connection
- <- install_ipsec_sa
-
-void scan_proc_shunts(void)
- Every SHUNT_SCAN_INTERVAL scan /proc/net/ipsec_eroute.
- Delete any PASS eroute in the bare_shunt table that hasn't been used
- within the last SHUNT_PATIENCE seconds.
- For any HOLD for which Pluto hasn't received an ACQUIRE (possibly
- lost due to congestion), act as if an ACQUIRE were received.
-
-[in connection.c]
-
-struct connection *route_owner(struct connection *c, struct connection **erop)
- Find the connection to connection c's peer's client with the
- largest value of .routing. All other things being equal,
- preference is given to c. Return NULL if no connection is routed
- at all. If erop is non-null, sets it to a connection sharing both
- our client subnet and peer's client subnet with the largest value
- of .routing.
- The return value is used to find other connections sharing
- a route. The value of *erop is used to find other connections
- sharing an eroute.
- <- could_route (to find any conflicting routes or eroutes)
- <- unroute_connection (to find out if our route is still in use
- after this connection is finished with it)
- <- install_inbound_ipsec_sa (to find other IPSEC SAs for the
- same peer clients; when we find them WE KILL THEM; a
- kludge to deal with road warriors reconnecting)
- <- route_and_eroute (to find all the connections from which the
- route or eroute is being stolen)
-
-Uses:
-
-- setting up route & shunt eroute to TRAP packets for opportunism
- (whack --route). Perhaps also manually designating DROP, REJECT, or
- PASS for certain packets.
-
- whack_handle() responds to --route; calls route_connection()
-
-
-- removing same (whack --unroute)
-
- whack_handle() responds to --unroute; calls unroute_connection()
-
-- installing route & normal eroute for a newly negotiated group of
- outbound IPSEC SAs
-
- + perhaps an (additional) route is not needed: if the negotiation
- was initiated by a TRAPped outgoing packet, then there must
- already have been a route that got the packet to ipsecN. Mind
- you, it could have been the wrong N!
-
- install_ipsec_sa()
-
-- updating a normal eroute when a new group of IPSEC SAs replaces
- an old one due to rekeying.
-
- install_ipsec_sa()
-
-- replacing an old eroute when a negotiation fails. But this is
- tricky. If this was a rekeying, we should just leave the old
- normal eroute be -- it might still work. Otherwise, this was
- an initial negotiation: we should replace the shunt eroute
- with one appropriate for the failure context.
-
-- when a group of IPSEC SAs dies or is killed, and it had the eroute,
- its normal eroute should be replaced by a shunt eroute. If there
- was an attempt to replace the group, the replacement is in the
- failure context; otherwise the replacement is in the prospective
- context.

- *
- * In addition to defining these 6 macros, the packing convention

- *
- * If you're using Microsoft Developer Studio 5.0 to produce

- * preprocessor directive before including pkcs11.h or pkcs11t.h:
- *
- * #pragma pack(push, cryptoki, 1)
- *
- * and using the following preprocessor directive after including
- * pkcs11.h or pkcs11t.h:
- *
- * #pragma pack(pop, cryptoki)
- *
- * If you're using an earlier version of Microsoft Developer

- *
- *
- * 2. CK_DEFINE_FUNCTION(returnType, name): A macro which makes
- * an exportable Cryptoki library function definition out of a

- * might be defined by:
- *
- * #define CK_DEFINE_FUNCTION(returnType, name) \
- * returnType __export _far _pascal name
- *
- * In a UNIX environment, it might be defined by:
- *
- * #define CK_DEFINE_FUNCTION(returnType, name) \
- * returnType name
- *
- *
- * 3. CK_DECLARE_FUNCTION(returnType, name): A macro which makes
- * an importable Cryptoki library function declaration out of a
- * return type and a function name. It should be used in the
- * following fashion:
- *
- * extern CK_DECLARE_FUNCTION(CK_RV, C_Initialize)(
- * CK_VOID_PTR pReserved
- * );
- *
- * If you're using Microsoft Developer Studio 5.0 to declare a
- * function in a Win32 Cryptoki .dll, it might be defined by:
- *
- * #define CK_DECLARE_FUNCTION(returnType, name) \
- * returnType __declspec(dllimport) name
- *
- * If you're using an earlier version of Microsoft Developer
- * Studio to declare a function in a Win16 Cryptoki .dll, it
- * might be defined by:
- *
- * #define CK_DECLARE_FUNCTION(returnType, name) \
- * returnType __export _far _pascal name
- *
- * In a UNIX environment, it might be defined by:
- *
- * #define CK_DECLARE_FUNCTION(returnType, name) \
- * returnType name
- *
- *
- * 4. CK_DECLARE_FUNCTION_POINTER(returnType, name): A macro
- * which makes a Cryptoki API function pointer declaration or
- * function pointer type declaration out of a return type and a
- * function name. It should be used in the following fashion:
- *
- * // Define funcPtr to be a pointer to a Cryptoki API function
- * // taking arguments args and returning CK_RV.
- * CK_DECLARE_FUNCTION_POINTER(CK_RV, funcPtr)(args);
- *
- * or
- *
- * // Define funcPtrType to be the type of a pointer to a
- * // Cryptoki API function taking arguments args and returning
- * // CK_RV, and then define funcPtr to be a variable of type
- * // funcPtrType.
- * typedef CK_DECLARE_FUNCTION_POINTER(CK_RV, funcPtrType)(args);
- * funcPtrType funcPtr;
- *
- * If you're using Microsoft Developer Studio 5.0 to access
- * functions in a Win32 Cryptoki .dll, in might be defined by:
- *
- * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
- * returnType __declspec(dllimport) (* name)
- *
- * If you're using an earlier version of Microsoft Developer
- * Studio to access functions in a Win16 Cryptoki .dll, it might
- * be defined by:
- *
- * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
- * returnType __export _far _pascal (* name)
- *
- * In a UNIX environment, it might be defined by:
- *
- * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
- * returnType (* name)
- *
- *
- * 5. CK_CALLBACK_FUNCTION(returnType, name): A macro which makes
- * a function pointer type for an application callback out of
- * a return type for the callback and a name for the callback.
- * It should be used in the following fashion:
- *
- * CK_CALLBACK_FUNCTION(CK_RV, myCallback)(args);
- *
- * to declare a function pointer, myCallback, to a callback
- * which takes arguments args and returns a CK_RV. It can also
- * be used like this:
- *
- * typedef CK_CALLBACK_FUNCTION(CK_RV, myCallbackType)(args);
- * myCallbackType myCallback;
- *
- * If you're using Microsoft Developer Studio 5.0 to do Win32
- * Cryptoki development, it might be defined by:
- *
- * #define CK_CALLBACK_FUNCTION(returnType, name) \
- * returnType (* name)
- *
- * If you're using an earlier version of Microsoft Developer
- * Studio to do Win16 development, it might be defined by:
- *
- * #define CK_CALLBACK_FUNCTION(returnType, name) \
- * returnType _far _pascal (* name)
- *
- * In a UNIX environment, it might be defined by:
- *
- * #define CK_CALLBACK_FUNCTION(returnType, name) \
- * returnType (* name)
- *
- *
- * 6. NULL_PTR: This macro is the value of a NULL pointer.
- *
- * In any ANSI/ISO C environment (and in many others as well),
- * this should best be defined by
- *
- * #ifndef NULL_PTR
- * #define NULL_PTR 0
- * #endif
