The buffer is dynam- + ically allocated, and must be freed by the caller by calling free(3). + + You may want the length of the generated buffer such when calling + setsockopt(2). ipsec_get_policylen() will return the length. + + ipsec_dump_policy() converts IPsec policy structure into readable form. + Therefore, ipsec_dump_policy() can be regarded as inverse conversion of + ipsec_set_policy(). buf points to a IPsec policy structure, struct + sadb_x_policy. delim is a delimiter string, which is usually a blank + character. If you set delim to NULL, single whitespace is assumed. + ipsec_dump_policy() returns pointer to dynamically allocated string. It + is caller's responsibility to reclaim the region, by using free(3). + + policy is formatted as either of the following: + + direction discard + direction must be in or out. direction specifies which direc- + tion the policy needs to be applied. With discard policy, pack- + ets will be dropped if they match the policy. + + direction entrust + entrust means to consult to SPD defined by setkey(8). + + direction bypass + bypass means to be bypassed the IPsec processing. (packet will + be transmitted in clear). This is for privileged socket. + + direction ipsec request ... + ipsec means that the matching packets are subject to IPsec pro- + cessing. ipsec can be followed by one or more request string, + which is formatted as below: + + protocol / mode / src - dst [/level] + protocol is either ah, esp or ipcomp. + + mode is either transport or tunnel. + + src and dst specifies IPsec endpoint. src always means + ``sending node'' and dst always means ``receiving + node''. Therefore, when direction is in, dst is this + node and src is the other node (peer). If mode is + transport, Both src and dst can be omited. + + level must be set to one of the following: default, + use, require or unique. default means that the kernel + should consult the system default policy defined by + sysctl(8), such as net.inet.ipsec.esp_trans_deflev. + See ipsec(4) regarding the system default. use means + that a relevant SA can be used when available, since + the kernel may perform IPsec operation against packets + when possible. In this case, packets can be transmit- + ted in clear (when SA is not available), or encrypted + (when SA is available). require means that a relevant + SA is required, since the kernel must perform IPsec + operation against packets. unique is the same as + require, but adds the restriction that the SA for out- + bound traffic is used only for this policy. You may + need the identifier in order to relate the policy and + the SA when you define the SA by manual keying. You + can put the decimal number as the identifier after + unique like unique: number. number must be between 1 + and 32767 . If the request string is kept unambiguous, + level and slash prior to level can be omitted. How- + ever, it is encouraged to specify them explicitly to + avoid unintended behaviors. If level is omitted, it + will be interpreted as default. + + Note that there is a bit difference of specification from setkey(8).
