New Revision: 313330
URL: https://svnweb.freebsd.org/changeset/base/313330
Log:
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.

+.Sh NAME
+.Nm if_ipsec
+.Nd IPsec virtual tunneling interface
+.Sh SYNOPSIS
+The
+.Cm if_ipsec
+network interface is a part of the
+.Fx
+IPsec implementation.
+To compile it into the kernel, place this line in the kernel
+configuration file:
+.Bd -ragged -offset indent
+.Cd "options IPSEC"
+.Ed
+.Pp
+It can also be loaded as part of the
+.Cm ipsec
+kernel module if the kernel was compiled with
+.Bd -ragged -offset indent
+.Cd "options IPSEC_SUPPORT"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+network interface is targeted for creating route-based VPNs.
+It can tunnel IPv4 and IPv6 traffic over either IPv4 or IPv6 and secure
+it with ESP.
+.Pp
+.Nm
+interfaces are dynamically created and destroyed with the
+.Xr ifconfig 8
+.Cm create
+and
+.Cm destroy
+subcommands.
+The administrator must configure IPsec
+.Cm tunnel
+endpoint addresses.
+These addresses will be used for the outer IP header of ESP packets.
+The administrator can also configure the protocol and addresses for the inner
+IP header with
+.Xr ifconfig 8 ,
+and modify the routing table to route the packets through the
+.Nm
+interface.
+.Pp
+When the
+.Nm
+interface is configured, it automatically creates special security policies.
+These policies can be used to acquire security associations from the IKE daemon,
+which are needed for establishing an IPsec tunnel.
+It is also possible to create needed security associations manually with the
+.Xr setkey 8
+utility.
+.Pp
+Each
+.Nm
+interface has an additional numeric configuration option
+.Cm reqid Ar id .
+This
+.Ar id
+is used to distinguish traffic and security policies between several
+.Nm
+interfaces.
+The
+.Cm reqid
+can be specified on interface creation and changed later.
+If not specified, it is automatically assigned.
+Note that changing
+.Cm reqid
+will lead to generation of new security policies, and this
+may require creating new security associations.
+.Sh EXAMPLES
+The example below shows manual configuration of an IPsec tunnel
+between two FreeBSD hosts.
+Host A has the IP address 192.168.0.3, and host B has the IP address
+192.168.0.5.
+.Pp
+On host A:
+.Bd -literal -offset indent
+ifconfig ipsec0 create reqid 100
+ifconfig ipsec0 inet tunnel 192.168.0.3 192.168.0.5
+ifconfig ipsec0 inet 172.16.0.3/16 172.16.0.5
