* setkey(8): Clarify language around AEAD ciphers.John Baldwin2022-04-271-26/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | AEAD ciphers for IPsec combine both encryption and authentication. As such, ESP configurations using an AEAD cipher should not use a seperate authentication algorithm via -A. However, this was not apparent from the setkey manpage and 12.x and earlier did not perform sufficient argument validation permitting users to pair an explicit -A such as SHA256-HMAC with AES-GCM. (The result was a non-standard combination of AES-CTR with the specified MAC, but with the wrong initial block counter (and thus different keystream) compared to using AES-CTR as the cipher.) Attempt to clarify this in the manpage by explicitly calling out AEAD ciphers (currently only AES-GCM) and noting that AEAD ciphers should not use -A. While here, explicitly note which authentication algorithms can be used with esp vs esp-old. Also add subsection headings for the different algorithm lists and tidy some language. I did not convert the tables to column lists (Bl -column) though that would probably be more correct than using literal blocks (Bd -literal).

| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

* Introduce the concept of IPsec security policies scope.Andrey V. Elsukov2017-03-072-22/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
