* Add large replay widow support to setkey(8) and libipsec.Andrey V. Elsukov2017-04-131-1/+42
| | | | | | | | | | | | | | | | | | | | When the replay window size is large than UINT8_MAX, add to the request the SADB_X_EXT_SA_REPLAY extension header that was added in r309144. Also add support of SADB_X_EXT_NAT_T_TYPE, SADB_X_EXT_NAT_T_SPORT, SADB_X_EXT_NAT_T_DPORT, SADB_X_EXT_NAT_T_OAI, SADB_X_EXT_NAT_T_OAR, SADB_X_EXT_SA_REPLAY, SADB_X_EXT_NEW_ADDRESS_SRC, SADB_X_EXT_NEW_ADDRESS_DST extension headers to the key_debug that is used by `setkey -x`. Modify kdebug_sockaddr() to use inet_ntop() for IP addresses formatting. And modify kdebug_sadb_x_policy() to show policy scope and priority.

* Introduce the concept of IPsec security policies scope.Andrey V. Elsukov2017-03-071-4/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently are defined three scopes: global, ifnet, and pcb. Generic security policies that IKE daemon can add via PF_KEY interface or an administrator creates with setkey(8) utility have GLOBAL scope. Such policies can be applied by the kernel to outgoing packets and checked agains inbound packets after IPsec processing. Security policies created by if_ipsec(4) interfaces have IFNET scope. Such policies are applied to packets that are passed through if_ipsec(4) interface. And security policies created by application using setsockopt() IP_IPSEC_POLICY option have PCB scope. Such policies are applied to packets related to specific socket. Currently there is no way to list PCB policies via setkey(8) utility. Modify setkey(8) and libipsec(3) to be able distinguish the scope of security policies in the `setkey -DP` listing. Add two optional flags: '-t' to list only policies related to virtual *tunneling* interfaces, i.e. policies with IFNET scope, and '-g' to list only policies with GLOBAL scope. By default policies from all scopes are listed. To implement this PF_KEY's sadb_x_policy structure was modified. sadb_x_policy_reserved field is used to pass the policy scope from the kernel to userland. SADB_SPDDUMP message extended to support filtering by scope: sadb_msg_satype field is used to specify bit mask of requested scopes. For IFNET policies the sadb_x_policy_priority field of struct sadb_x_policy is used to pass if_ipsec's interface if_index to the userland. For GLOBAL policies sadb_x_policy_priority is used only to manage order of security policies in the SPDB. For IFNET policies it is not used, so it can be used to keep if_index. After this change the output of `setkey -DP` now looks like: # setkey -DPt 0.0.0.0/0[any] 0.0.0.0/0[any] any in ipsec esp/tunnel/87.250.242.144-87.250.242.145/unique:145 spid=7 seq=3 pid=58025 scope=ifnet ifname=ipsec0 refcnt=1 # setkey -DPg ::/0 ::/0 icmp6 135,0 out none spid=5 seq=1 pid=872 scope=global refcnt=1 No objection from: #network Obtained from: Yandex LLC MFC after: 2 weeks Sponsored by: Yandex LLC Differential Revision: https://reviews.freebsd.org/D9805 Notes: svn path=/head/; revision=314812
* Merge projects/ipsec into head/.Andrey V. Elsukov2017-02-062-15/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Small summary ------------- o Almost all IPsec releated code was moved into sys/netipsec. o New kernel modules added: ipsec.ko and tcpmd5.ko. New kernel option IPSEC_SUPPORT added. It enables support for loading and unloading of ipsec.ko and tcpmd5.ko kernel modules. o IPSEC_NAT_T option was removed. Now NAT-T support is enabled by default. The UDP_ENCAP_ESPINUDP_NON_IKE encapsulation type support was removed. Added TCP/UDP checksum handling for inbound packets that were decapsulated by transport mode SAs. setkey(8) modified to show run-time NAT-T configuration of SA. o New network pseudo interface if_ipsec(4) added. For now it is build as part of ipsec.ko module (or with IPSEC kernel). It implements IPsec virtual tunnels to create route-based VPNs. o The network stack now invokes IPsec functions using special methods. The only one header file <netipsec/ipsec_support.h> should be included to declare all the needed things to work with IPsec. o All IPsec protocols handlers (ESP/AH/IPCOMP protosw) were removed. Now these protocols are handled directly via IPsec methods. o TCP_SIGNATURE support was reworked to be more close to RFC. o PF_KEY SADB was reworked: - now all security associations stored in the single SPI namespace, and all SAs MUST have unique SPI. - several hash tables added to speed up lookups in SADB. - SADB now uses rmlock to protect access, and concurrent threads can do SA lookups in the same time. - many PF_KEY message handlers were reworked to reflect changes in SADB. - SADB_UPDATE message was extended to support new PF_KEY headers: SADB_X_EXT_NEW_ADDRESS_SRC and SADB_X_EXT_NEW_ADDRESS_DST. They can be used by IKE daemon to change SA addresses. o ipsecrequest and secpolicy structures were cardinally changed to avoid locking protection for ipsecrequest. Now we support only limited number (4) of bundled SAs, but they are supported for both INET and INET6. o INPCB security policy cache was introduced. Each PCB now caches used security policies to avoid SP lookup for each packet. o For inbound security policies added the mode, when the kernel does check for full history of applied IPsec transforms. o References counting rules for security policies and security associations were changed. The proper SA locking added into xform code. o xform code was also changed. Now it is possible to unregister xforms. tdb_xxx structures were changed and renamed to reflect changes in SADB/SPDB, and changed rules for locking and refcounting.

* IPsec RFC6479 support for replay window sizes up to 2^32 - 32 packets.Fabien Thomas2016-11-252-1/+5
| | | | | | | | | | | | | | | | | | | Since the previous algorithm, based on bit shifting, does not scale with large replay windows, the algorithm used here is based on RFC 6479: IPsec Anti-Replay Algorithm without Bit Shifting. The replay window will be fast to be updated, but will cost as many bits in RAM as its size. The previous implementation did not provide a lock on the replay window, which may lead to replay issues.
