Lives longer. - -In order to recognize exchanges and SAs it is good to know what constitutes -their identities: - -Phase 1 exchange Cookie pair (apart from the first message of course, - where the responder cookie is zero. - -ISAKMP SA Cookie pair. I.e. there exists a one-to-one - mapping to the negotiation in this case. - -Phase 2 exchange Cookie pair + message ID. - -Generic SA Cookie pair + message ID + SPI. - -However it would be really nice to have a name of any SA that is natural -to use for human beings, for things like deleting SAs manually. The simplest -ID would be the struct sa address. Another idea would be some kind of sequence -number, either global or per-destination. Right now I have introduced a name -for SAs, non-unique, that binds together SAs and their configuration -parameters. This means both manual exchange runs and rekeying are simpler. -Both struct exchange and struct sa does hold a reference count, but this is -not entirely like a reference count in the traditional meaning where -every reference gets counted. Perhaps it will be in the future, but for now -we increment the count at allocation time and at times we schedule events -tha might happen sometime in the future where we will need the structure. -These events then realeases its reference when done. This way intermediate -deallocation of these structures are OK. - -The basic idea of control flow ------------------------------- - -The main loop just waits for events of any kind. Supposedly a message -comes in, then the daemon looks to see if the cookies describes an -existing ISAKMP SA, if they don't and the rcookie is zero, it triggers a -setup of a new ISAKMP SA. An exhaustive validation phase of the message -is gone through at this stage. If anything goes wrong, we drop the packet -and probably send some notification back. After the SA is found we try to -locate the exchange object and advance its state, else we try to create a -new exchange. - -Need exchanges be an abstraction visible in the code? If so an exchange is -roughly a very simple FSM (only timeouts and retransmissions are events that -does not just advance the state through a sequential single path). The -informational exchange is such a special case, I am not sure it's interesting -to treat as an exchange in the logic of the implementation. The only reason -to do so would be to keep the implementation tightly coupled to the -specification for ease of understanding. As the code looks now, exchanges -*are* an abstraction in the code, and it has proven to be a rather nice -way of having things. - -When the exchange has been found the exchange engine "runs" a script which -steps forward for each incoming message, and on each reply to them. - -Payload parsing details ------------------------ - -After the generic header has been validated, we do a generic payload -parsing pass over the message and sort out the payloads into buckets indexed -by the payload type. Note that proposals and transforms are part of the SA -payloads. We then pass over them once more validating each payload -in numeric payload type order. This makes SA payloads come naturally first. - -Messages --------- - -I am not sure there is any use in sharing the message structure for both -incoming and outgoing messages but I do it anyhow. Specifically there are -certain fields which only makes sense in one direction. Incoming messages -only use one segment in the iovec vector, while outgoing has one segment per -payload as well as one for the ISAKMP header. The iovec vector is -reallocated for each payload added, maybe we should do it in chunks of a -number of payloads instead, like 10 or so. - -Design "errors" ---------------- - -Currently there are two "errors" in our design. The first one is that the -coupling between the IPsec DOI and IKE is tight. It should be separated by -a clean interface letting other key exchange models fit in instead of IKE. -The second problem is that we need a protocol-specific opaque SA part -in the DOI specific one. Now both IPsec ESP attributes takes place even -in ISAKMP SA structures. - -User control ------------- - -In order to control the daemon you send commands through a FIFO called -isakmpd.fifo. The commands are one-letter codes followed by arguments. -For now, eleven such commands are implemented: - -c connect Establish a connection with a peer -C configure Add or remove configuration entries -d delete Delete an SA given cookies and message-IDs -D debug Change logging level for a debug class -p packet capture Enable/disable packet capture feature -r report Report status information of the daemon -t teardown Teardown a connection -Q quit Quit the isakmpd process -R reinitialize Reinitialize isakmpd (re-read configuration file) -S report SA Report SA information to file /var/run/isakmp_sa -T teardown all Teardown all Phase 2 connections - -For example you can do: - -c ISAKMP-peer - -In order to delete an SA you use the 'd' command. However this is not yet -supported. - -To alter the level of debugging in the "LOG_MISC" logging class to 99 you do: - -D 0 99 - -The report command is just an "r", and results in a list of active exchanges -and security associations. - -The "C" command takes 3 subcommands: set, rm and rms, for adding and removing -entries + remove complete sections respectively. Examples: - -C set [Net-A]:Address=192.168.0.0 -C rm [Net-A]:Address -C rms [Net-A] - -All these commands are atomic, i.e. they are not collected into larger -transactions, which there should be a way to do, but currently isn't. - -The FIFO UI is also described in the isakmpd(8) man page. - -In addition to giving commands over the FIFO, you may send signals to the -daemon. Currently two such signals are implemented: - -SIGHUP Re-initialize isakmpd (not fully implemented yet) -SIGUSR1 Generate a report, much as the "r" FIFO command. - -For example, to generate a report, you do: - -unix# kill -USR1 <PID of isakmpd process> - -The constant descriptions -------------------------- - -We have invented a simple constant description language, for the sake -of easily getting textual representations of manifest constants. -The syntax is best described by an example: - -GROUP - CONSTANT_A 1 - CONSTANT_B 2 -. - -This defines a constant map "group" with the following two defines: - -#define GROUP_CONSTANT_A 1 -#define GROUP_CONSTANT_B 2 - -We can now get the textual representation by: - - cp = constant_name (group, foo); - -Here foo is an integer with either of the two constants as a value. - -The field descriptions ----------------------- - -There is language for describing header and payload layouts too, -similar to the constant descriptions. Here too I just show an example: - -RECORD_A - FIELD_A raw 4 - FIELD_B num 2 - FIELD_C mask 1 group_c_cst - FIELD_D ign 1 - FIELD_E cst 2 group_e1_cst,group_e2_cst -. - -RECORD_B : RECORD_A - FIELD_F raw -. - -This creates some utility constants like RECORD_A_SZ, RECORD_A_FIELD_A_LEN, -RECORD_A_FIELD_A_OFF, RECORD_A_FIELD_B_LEN etc. The *_OFF contains the -octet offset into the record and the *_LEN constants are the lengths. -The type fields can be: raw, num, mask, ign & cst. Raw are used for -octet buffers, num for (unsigned) numbers of 1, 2 or 4 octet's length -in network byteorder, mask is a bitmask where the bit values have symbols -coupled to them via the constant maps given after the length in octets -(also 1, 2 or 4). Ign is just a filler type, ot padding and lastly cst -denotes constants whose values can be found in the given constant map(s). -The last field in a record can be a raw, without a length, then just an -_OFF symbol will be generated. You can offset the first symbol to the -size of another record, like is done above for RECORD_B, i.e. in that -case RECORD_A_SZ == RECORD_B_FIELD_F_OFF. All this data are collected -in struct field arrays which makes it possible to symbolically print out -entire payloads in readable form via field_dump_payload. - -Configuration -------------- - -Internally isakmpd uses a section-tag-value triplet database for -configuration. Currently this happen to map really well to the -configuration file format, which on the other hand does not map -equally well to humans. It is envisioned that the configuration -database should be dynamically modifiable, and through a lot of -differnet mechanisms. Therefore we have designed an API for this -purpose. - -int conf_begin (); -int conf_set (int transaction, char *section, char *tag, char *value, - int override); -int conf_remove (int transaction, char *section, char *tag); -int conf_remove_section (int transaction, char *section); -int conf_end (int transaction, int commit); - -The caller will always be responsible for the memory management of the -passed strings, conf_set will copy the values, and not use the original -strings after it has returned. Return value will be zero on success and -non-zero otherwise. Note that the conf_remove* functions consider not -finding anything to remove as failure. - -Identification --------------- - -ISAKMP supports a lot of identity types, and we should too of course. - -* Phase 1, Main mode or Aggressive mode - -Today when we connect we do it based on the peer's IP address. That does not -automatically mean we should do policy decision based on IPs, rather we should -look at the ID the peer provide and get policy info keyed on that. - -Perhaps we get an ID saying the peer is FQDN niklas.hallqvist.se, then our -policy rules might look like: - -[IQ_FQDN] -# If commented, internal verification is used -#Verificator= verify_fqdn -Accept= no - -[ID_FQDN niklas.hallqvist.se] -Policy= MY_POLICY_001 - -[MY_POLICY_001] -# Whatever policy rules we might have. -Accept= yes - -Which means niklas.hallqvist.se is allowed to negotiate SAs with us, but -noone else. - -* Phase 2, Quick mode - -In quick mode the identities are implicitly the IP addresses of the peers, -which must mean the IP addresses actually used for the ISAKMP tunnel. -Otherwise we today support IPV4_ADDR & IPV4_ADDR_SUBNET as ID types. - -X509-Certificates ------------------ -To use RSA Signature mode you are required to generate certificates. -This can be done with ssleay, see man ssl. But the X509 certificates -require a subjectAltname extension that can either be an IPV4 address, -a User-FQDN or just FQDN. ssleay can not create those extension, -insead use the x509test program in regress/x509 to modify an existing -certificate. It will insert the subjectAltname extension and sign it -with the provided private Key. The resulting certificate then needs -to be stored in the directory pointed to by "Certs-directory" in -section "X509-certificates". - -License to use --------------- -/* - * Copyright (c) 1999 Niklas Hallqvist.

IKE key management daemon -.Sh SYNOPSIS -.Nm isakmpd -.Bk -words -.Op Fl 4 -.Op Fl 6 -.Op Fl c Ar config-file -.Op Fl a -.Op Fl d -.Op Fl D Ar class=level -.Op Fl f Ar fifo -.Op Fl i Ar pid-file -.Op Fl n -.Op Fl p Ar listen-port -.Op Fl P Ar local-port -.Op Fl K -.Op Fl L -.Op Fl l Ar packetlog-file -.Op Fl r Ar seed -.Op Fl R Ar report-file -.Op Fl v -.Ek -.Sh DESCRIPTION -The -.Nm -daemon establishes security associations for encrypted -and/or authenticated network traffic. -At this moment, and probably forever, this means -.Xr ipsec 4 -traffic. -.Pp -The way -.Nm -goes about its work is by maintaining an internal configuration -as well as a policy database which describes what kinds of SAs to negotiate, -and by listening for different events that trigger these negotiations. -The events that control -.Nm -consist of negotiation initiations from a remote party, user input via -a FIFO or by signals, upcalls from the kernel via a -.Dv PF_KEY -socket, and lastly by scheduled events triggered by timers running out. -.Pp -Most uses of -.Nm -will be to implement so called "virtual private -networks" or VPNs for short. -The -.Xr vpn 8 -manual page describes how to set up -.Nm -for a simple VPN. -For other uses, some more knowledge of IKE as a protocol is required. -One source of information are the RFCs mentioned below. -.Pp -On startup -.Nm -forks into two processes for privilege separation. -The unprivileged child jails itself with -.Xr chroot 8 -to -.Pa /var/empty . -The privileged process communicates with the child, reads configuration files -and PKI information and binds to privileged ports on its behalf. -See -.Sx CAVEATS -section below. -.Pp -The options are as follows: -.Bl -tag -width Ds -.It Fl 4 | Fl 6 -These options control what address family -.Pf ( Dv AF_INET -and/or -.Dv AF_INET6 ) -.Nm -will use. -The default is to use both IPv4 and IPv6. -.It Fl a -If given, -.Nm -does not set up flows automatically. -This is useful when flows are configured with -.Xr ipsecadm 4 -or by other programs like -.Xr bgpd 8 . -Thus -.Nm -only takes care of the SA establishment. -.It Fl c Ar config-file -If given, the -.Fl c -option specifies an alternate configuration file instead of -.Pa /etc/isakmpd/isakmpd.conf . -As this file may contain sensitive information, it must be readable -only by the user running the daemon. -.Nm -will reread the configuration file when sent a -.Dv SIGHUP -signal. -.It Fl d -The -.Fl d -option is used to make the daemon run in the foreground, logging to stderr. -.It Xo Fl D -.Ar class Ns = Ns Ar level -.Xc -Debugging class. -It's possible to specify this argument many times. -It takes a parameter of the form -.Ar class Ns = Ns Ar level , -where both -.Ar class -and -.Ar level -are numbers. -.Ar class -denotes a debugging class, and -.Ar level -the level you want that debugging class to -limit debug printouts at (i.e., all debug printouts above the level specified -will not output anything). -If -.Ar class -is set to -.Sq A , -then all debugging classes are set to the specified level. -.Pp -Valid values for -.Ar class -are as follows: -.Pp -.Bl -tag -width 2n -compact -offset indent -.It 0 -Misc -.It 1 -Transport -.It 2 -Message -.It 3 -Crypto -.It 4 -Timer -.It 5 -Sysdep -.It 6 -SA -.It 7 -Exchange -.It 8 -Negotiation -.It 9 -Policy -.It 10 -FIFO user interface -.It A -All -.El -.Pp -Currently used values for -.Ar level -are 0 to 99. -.It Fl f Ar fifo -The -.Fl f -option specifies the -.Tn FIFO -(a.k.a. named pipe) where the daemon listens for -user requests. -If the path given is a dash -.Pq Sq \&- , -.Nm -will listen to stdin instead. -.It Fl i Ar pid-file -By default the PID of the daemon process will be written to -.Pa /var/run/isakmpd.pid . -This path can be overridden by specifying another one as the argument to the -.Fl i -option. -.It Fl n -When the -.Fl n -option is given, the kernel will not take part in the negotiations. -This is a non-destructive mode, so to speak, in that it won't alter any -SAs in the IPsec stack. -.It Fl p Ar listen-port -The -.Fl p -option specifies the listen port the daemon will bind to. -.It Fl P Ar local-port -On the other hand, the port specified to capital -.Fl P -will be what the daemon binds its local end to when acting as -initiator. -.It Fl K -When this option is given, -.Nm -does not read the policy configuration file and no -.Xr keynote 4 -policy check is accomplished. -This option can be used when policies for flows and SA establishment are -arranged by other programs like -.Xr ipsecadm 8 -or -.Xr bgpd 8 . -.It Fl L -Enable IKE packet capture. -When this option is given, -.Nm -will capture to file an unencrypted copy of the negotiation packets it -is sending and receiving. -This file can later be read by -.Xr tcpdump 8 -and other utilities using -.Xr pcap 3 . -.It Fl l Ar packetlog-file -As option -.Fl L -above, but capture to a specified file. -.It Fl r Ar seed -If given, a deterministic random number sequence will be used internally. -This is useful for setting up regression tests. -.It Fl R Ar report-file -When you signal -.Nm -a -.Dv SIGUSR1 , -it will report its internal state to a report file, normally -.Pa /var/run/isakmpd.report , -but this can be changed by feeding -the file name as an argument to the -.Fl R -flag. -.It Fl v -Enables verbose logging. -Normally, -.Nm -is silent and outputs only messages when a warning or an error occurs. -With verbose logging -.Nm -reports successful completion of phase 1 (Main and Aggressive) and phase 2 -(Quick) exchanges

QM-ESP-3DES-SHA-PFS-SUITE is used as the default. -.It Em Acquire-Only -If this tag is defined, -.Nm isakmpd -will not set up flows automatically. -This is useful when flows are configured with -.Xr ipsecadm 4 -or by other programs like -.Xr bgpd 8 . -Thus -.Nm isakmpd -only takes care of the SA establishment. -.It Em Check-interval -The interval between watchdog checks of connections we want up at all -times. -.It Em DPD-check-interval -The interval between RFC 3706 (Dead Peer Detection) messages. -The default value is 0 (zero), which means DPD is disabled. -.It Em Exchange-max-time -How many seconds should an exchange maximally take to set up before we -give up. -.It Em Listen-on -A list of IP-addresses OK to listen on. -This list is used as a filter for the set of addresses the

message be retransmitted before giving up. -.It Em Shared-SADB -If this tag is defined, whatever the value is, some semantics of -.Nm -are changed so that multiple instances can run on top of one SADB -and set up SAs with each other. -Specifically this means replay -protection will not be asked for, and errors that can occur when -updating an SA with its parameters a 2nd time will be ignored. -.It Em Use-Keynote -This tag controls the use of -.Xr keynote 4 -policy checking. -The default value is -.Qq yes , -which enables the policy checking. -When set to any other value, policies will not be

configuration file for the -.Nm isakmpd -daemon managing security association and key management for the -.Xr ipsec 4 -layer of the kernel's networking stack. -.Pp -The -.Xr isakmpd 8 -daemon (also known as IKE, for Internet Key Exchange) is used when two -systems need to automatically set up a pair of Security Associations -(SAs) for securely communicating using IPsec. -IKE operates in two stages: -.Pp -In the first stage (Main or Identity Protection Mode), the two IKE -daemons establish a secure link between themselves, fully -authenticating each other and establishing key material for -encrypting/authenticating future communications between them. -This step is typically only performed once for every pair of IKE daemons. -.Pp -In the second stage (also called Quick Mode), the two IKE daemons -create the pair of SAs for the parties that wish to communicate using -IPsec. -These parties may be the hosts the IKE daemons run on, a host -and a network behind a firewall, or two networks behind their -respective firewalls. -At this stage, the exact parameters of the SAs -(e.g., algorithms to use, encapsulation mode, lifetime) and the -identities of the communicating parties (hosts, networks, etc.) are -specified. -The reason for the existence of Quick Mode is to allow for fast -SA setup, once the more heavy-weight Main Mode has been completed. -Generally, Quick Mode uses the key material derived from Main Mode to -provide keys to the IPsec transforms to be used. -Alternatively, a new -Diffie-Hellman computation may be performed (significantly slowing -down the exchange, but at the same time providing Perfect Forward -Secrecy (PFS)). -Briefly, this means that even should an attacker -manage to break long-term keys used in other sessions (or, -specifically, if an attacker breaks the Diffie-Hellman exchange -performed during Main Mode), they will not be able to decrypt this -traffic. -Normally, no PFS is provided (the key material used by the -IPsec SAs established as a result of this exchange will be derived -from the key material of the Main Mode exchange), allowing for a -faster Quick Mode exchange (no public key computations). -.Pp -IKE proposals are "suggestions" by the initiator of an exchange to the -responder as to what protocols and attributes should be used on a -class of packets. -For example, a given exchange may ask for ESP with -3DES and MD5 and AH with SHA1 (applied successively on the same -packet), or just ESP with Blowfish and RIPEMD-160. -The responder -examines the proposals and determines which of them are acceptable, -according to policy and any credentials. -.Pp -The following paragraphs assume some knowledge of the contents of the -.Xr keynote 4 -and -.Xr keynote 5 -man pages. -.Pp -In the KeyNote policy model for IPsec, no distinction is currently -made based on the ordering of AH and ESP in the packet. -Should this -change in the future, an appropriate attribute (see below) will be -added. -.Pp -The goal of security policy for IKE is thus to determine, based on -local policy (provided in the -.Nm isakmpd.policy -file), credentials provided during the IKE exchanges (or obtained -through other means), the SA attributes proposed during the exchange, -and perhaps other (side-channel) information, whether a pair of SAs -should be installed in the system (in fact, whether both the IPsec SAs -and the flows should be installed). -For each proposal suggested by or -to the remote IKE daemon, the KeyNote system is consulted as to -whether the proposal is acceptable based on local policy (contained in -.Nm isakmpd.policy , -in the form of policy assertions) and remote credentials (e.g., -KeyNote credentials or X509 certificates provided by the remote IKE -daemon). -.Pp -.Nm isakmpd.policy -is simply a flat -.Xr ascii 7 -file containing KeyNote policy assertions, separated by blank lines -(note that KeyNote assertions may not contain blank lines). -.Nm isakmpd.policy -is read when -.Xr isakmpd 8 -is first started, and every time it receives a -.Dv SIGHUP -signal. -The new policies read will be used for all new Phase 2 (IPsec) -SAs established from that point on (even if the associated Phase 1 SA -was already established when the new policies were loaded). -The policy change will not affect already established Phase 2 SAs. -.Pp -For more details on KeyNote assertion format, please see -.Xr keynote 5 . -Briefly, KeyNote policy assertions used in IKE have the following -characteristics: -.Bl -bullet -.It -The Authorizer field is typically "POLICY" (but see the examples -below, for use of policy delegation). -.It -The Licensees field can be an expression of passphrases used for -authentication of the Main Mode exchanges, and/or public keys -(typically, X509 certificates), and/or X509 distinguished names. -.It -The Conditions field contains an expression of attributes from the -IPsec policy action set (see below as well as the keynote syntax man -page for more details). -.It -The ordered return-values set for IPsec policy is "false, true". -.El -.Pp -For an explanation of these fields and their semantics, see -.Xr keynote 5 . -.Pp -For example, the following policy assertion: -.Bd -literal - Authorizer: "POLICY" - Licensees: "passphrase:foobar" || "x509-base64:abcd==" || - "passphrase-md5-hex:3858f62230ac3c915f300c664312c63f" || - "passphrase-sha1-hex:8843d7f92416211de9ebb963ff4ce28125932878" - Conditions: app_domain == "IPsec policy" && esp_present == "yes" - && esp_enc_alg != "null" -> "true"; -.Ed -.Pp -says that any proposal from a remote host that authenticates using the -passphrase "foobar" or the public key contained in the X509 -certificate encoded as "abcd==" will be accepted, as long as it -contains ESP with a non-null algorithm (i.e., the packet will be -encrypted). -The last two authorizers are the MD5 and SHA1 hashes respectively of -the passphrase "foobar". -This form may be used instead of the "passphrase:..." one to protect -the passphrase as included in the policy file (or as distributed in a -signed credential). -.Pp -The following policy assertion: -.Bd -literal - Authorizer: "POLICY" - Licensees: "DN:/CN=CA Certificate" - Conditions: app_domain == "IPsec policy" && esp_present == "yes" - && esp_enc_alg != "null" -> "true"; -.Ed -.Pp -is similar to the previous one, but instead of including a complete -X509 credential in the Licensees field, only the X509 certificate's -Subject Canonical Name needs to be specified (note that the "DN:" -prefix is necessary). -.Pp -KeyNote credentials have the same format as policy assertions, with -one difference: the Authorizer field always contains a public key, and -the assertion is signed (and thus its integrity can be -cryptographically verified). -Credentials are used to build chains of delegation of authority. -They can be exchanged during an IKE exchange, -or can be retrieved through some out-of-band mechanism (no such -mechanism is currently supported in this implementation however). -See -.Xr isakmpd.conf 5 -on how to specify what credentials to send in an IKE exchange. -.Pp -Passphrases that appear in the Licensees field are encoded as the -string "passphrase:", followed by the passphrase itself -(case-sensitive). -Alternatively (and preferably), they may be encoded using the -"passphrase-md5-hex:" or "passphrase-sha1-hex:" prefixes, followed -by the -.Xr md5 1 -or -.Xr sha1 1 -hash of the passphrase itself, encoded as a hexadecimal string (using -lower-case letters only). -.Pp -When X509-based authentication is performed in Main Mode, any X509 -certificates received from the remote IKE daemon are converted to very -simple KeyNote credentials. -The conversion is straightforward: the -issuer of the X509 certificate becomes the Authorizer of the KeyNote -credential, the subject becomes the only Licensees entry, while the -Conditions field simply asserts that the credential is only valid for -"IPsec policy" use (see the app_domain action attribute below). -.Pp -Similarly, any X509 CA certificates present in the directory pointed -to by the appropriate -.Xr isakmpd.conf 5 -entry, are converted to such pseudo-credentials. -This allows one to -write KeyNote policies that delegate specific authority to CAs (and -the keys those CAs certify, recursively). -.Pp -For more details on KeyNote assertion format, see -.Xr keynote 5 . -.Pp -Information about the proposals, the identity of the remote IKE -daemon, the packet classes to be protected, etc. are encoded in what -is called an action set. -The action set is composed of name-value -attributes, similar in some ways to shell environment variables. -These values are initialized by -.Nm isakmpd -before each query to the KeyNote system, and can be tested against in -the Conditions field of assertions. -See -.Xr keynote 4 -and -.Xr keynote 5 -for more details on the format and semantics of the Conditions field. -.Pp -Note that assertions and credentials can make references to -non-existent attributes without catastrophic failures (access may be -denied, depending on the overall structure, but will not be -accidentally granted). -One reason for credentials referencing -non-existent attributes is that they were defined within a specific -implementation or network only. -.Pp -In the following attribute set, IPv4 addresses are encoded as ASCII -strings in the usual dotted-quad format. -However, all quads are three digits long. -For example, the IPv4 address -.Va 10.128.1.12 -would be encoded as -.Va 010.128.001.012 . -Similarly, IPv6 addresses are encoded in the standard x:x:x:x:x:x:x:x -format, where the 'x's are the hexadecimal values of the eight 16-bit -pieces of the address. -All 'x's are four digits long. -For example, the address -.Va 1080:0:12:0:8:800:200C:417A -would be encoded as -.Va 1080:0000:0012:0000:0008:0800:200C:417A . -.Pp -The following attributes are currently defined:
