Subversion Repositories configs

#
#       The WiMAX module currently takes no configuration.
#
#       It should be listed in the "authorize" and "preacct" sections.
#       This enables the module to fix the horrible binary version
#       of Calling-Station-Id to the normal format, as specified in
#       RFC 3580, Section 3.21.
#
#       In order to calculate the various WiMAX keys, the module should
#       be listed in the "post-auth" section.  If EAP authentication
#       has been used, AND the EAP method derives MSK and EMSK, then
#       the various WiMAX keys can be calculated.
#
#       Some useful things to remember:
#
#       WiMAX-MSK = EAP MSK, but is 64 octets.
#
#       MIP-RK-1 = HMAC-SHA256(ESMK, "miprk@wimaxforum.org" | 0x00020001)
#       MIP-RK-2 = HMAC-SHA256(ESMK, MIP-RK-1 | "miprk@wimaxforum.org" | 0x00020002)
#       MIP-RK = MIP-RK-1 | MIP-RK-2
#
#       MIP-SPI = first 4 octets of HMAC-SHA256(MIP-RK, "SPI CMIP PMIP")
#               plus some magic... you've got to track *all* MIP-SPI's
#               on your system!
#
#       SPI-CMIP4 = MIP-SPI
#       SPI-PMIP4 = MIP-SPI + 1
#       SPI-CMIP6 = MIP-SPI + 2
#
#       MN-NAI is the Mobile node NAI.  You have to create it, and put
#       it into the request or reply as something like:
#
#               WiMAX-MN-NAI = "%{User-Name}"
#
#       You will also have to have the appropriate IP address (v4 or v6)
#       in order to calculate the keys below.
#
#       Lifetimes are derived from Session-Timeout.  It needs to be set
#       to some useful number.
#
#       The hash function below H() is HMAC-SHA1.
#
#
#       MN-HA-CMIP4 = H(MIP-RK, "CMIP4 MN HA" | HA-IPv4 | MN-NAI)
#
#               Where HA-IPv4 is        WiMAX-hHA-IP-MIP4
#               or maybe                WiMAX-vHA-IP-MIP4
#
#               Which goes into         WiMAX-MN-hHA-MIP4-Key
#               or maybe                WiMAX-RRQ-MN-HA-Key
#               or maybe even           WiMAX-vHA-MIP4-Key
#
#       The corresponding SPI is SPI-CMIP4, which is MIP-SPI,
#
#               which goes into         WiMAX-MN-hHA-MIP4-SPI
#               or maybe                WiMAX-RRQ-MN-HA-SPI
#               or even                 WiMAX-MN-vHA-MIP4-SPI
#
#       MN-HA-PMIP4 = H(MIP-RK, "PMIP4 MN HA" | HA-IPv4 | MN-NAI)
#       MN-HA-CMIP6 = H(MIP-RK, "CMIP6 MN HA" | HA-IPv6 | MN-NAI)
#
#               both with similar comments to above for MN-HA-CMIP4.
#
#       In order to tell which one to use (CMIP4, PMIP4, or CMIP6),
#       you have to set WiMAX-IP-Technology in the reply to one of
#       the appropriate values.
#
#
#       FA-RK = H(MIP-RK, "FA-RK")
#
#       MN-FA = H(FA-RK, "MN FA" | FA-IP | MN-NAI)
#
#               Where does the FA-IP come from?  No idea...
#
#
#       The next two keys (HA-RK and FA-HA) are not generated
#       for every authentication request, but only on demand.
#
#       HA-RK = 160-bit random number assigned by the AAA server
#               to a specific HA.
#
#       FA-HA = H(HA-RK, "FA-HA" | HA-IPv4 | FA-CoAv4 | SPI)
#
#               where HA-IPv4 is as above.
#               and FA-CoAv4 address of the FA as seen by the HA
#               and SPI is the relevant SPI for the HA-RK.
#
#       DHCP-RK = 160-bit random number assigned by the AAA server
#                 to a specific DHCP server.  vDHCP-RK is the same
#                 thing.

        #  the WiMAX-MSK attribute.
        #
        #  Other WiMAX equipment request that the MS-MPPE-*-Key

        #
        #  By default, the EAP modules sends MS-MPPE-*-Key attributes.
        #  The default virtual server (raddb/sites-available/default)
        #  contains examples of adding the WiMAX-MSK.
        #
        #  This configuration option makes the WiMAX module delete
        #  the MS-MPPE-*-Key attributes.  The default is to leave
        #  them in place.
        #
        #  If the keys are deleted (by setting this to "yes"), then
        #  the WiMAX-MSK attribute is automatically added to the reply.
