"Fast IPsec": this is an experimental IPsec implementation that is derived from the KAME IPsec implementation, but with heavy borrowing and influence of openbsd. A key feature of this implementation is that it uses the kernel crypto framework to do all crypto work so when h/w crypto support is present IPsec operation is automatically accelerated. Otherwise the protocol implementations are rather differet while the SADB and policy management code is very similar to KAME (for the moment). Note that this implementation is enabled with a FAST_IPSEC option. With this you get all protocols; i.e. there is no FAST_IPSEC_ESP option. FAST_IPSEC and IPSEC are mutually exclusive; you cannot build both into a single system. This software is well tested with IPv4 but should be considered very experimental (i.e. do not deploy in production environments). This software does NOT currently support IPv6. In fact do not configure FAST_IPSEC and INET6 in the same system. Obtained from: KAME + openbsd Supported by: Vernier Networks

sys: further adoption of SPDX licensing ID tags. 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. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.

Disable IPsec debugging code by default when IPSEC_DEBUG kernel option is not specified. Due to the long call chain IPsec code can produce the kernel stack exhaustion on the i386 architecture. The debugging code usually is not used, but it requires a lot of stack space to keep buffers for strings formatting. This patch conditionally defines macros to disable building of IPsec debugging code. IPsec currently has two sysctl variables to configure debug output: * net.key.debug variable is used to enable debug output for PF_KEY protocol. Such debug messages are produced by KEYDBG() macro and usually they can be interesting for developers. * net.inet.ipsec.debug variable is used to enable debug output for DPRINTF() macro and ipseclog() function. DPRINTF() macro usually is used for development debugging. ipseclog() function is used for debugging by administrator. The patch disables KEYDBG() and DPRINTF() macros, and formatting buffers declarations when IPSEC_DEBUG is not present in kernel config. This reduces stack requirement for up to several hundreds of bytes. The net.inet.ipsec.debug variable still can be used to enable ipseclog() messages by administrator.

#ifdef IPSEC_DEBUG
Merge projects/ipsec into head/. 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.
