Processing Sections

All of the processing sections have been renamed. Sorry, but this was required for the new features in v4.

Old Name New Name

Old Name	New Name
`authorize`	`recv Access-Request`
`authenticate`	`authenticate <Auth-Type>`
`post-auth`	`send Access-Accept`

`preacct`	`recv Accounting-Request`
`accounting`	`accounting %{Acct-Status-Type}`
`accounting`	`send Accounting-Response`

`recv-coa`	`recv CoA-Request`
`send-coa`	`send CoA-ACK`
`send-coa`	`send CoA-NAK`

`Post-Auth-Type Reject`	`send Access-Reject`
`Post-Auth-Type Challenge`	`send Access-Challenge`

authorize

recv Access-Request

authenticate

authenticate <Auth-Type>

post-auth

send Access-Accept

preacct

recv Accounting-Request

accounting

accounting %{Acct-Status-Type}

accounting

send Accounting-Response

recv-coa

recv CoA-Request

send-coa

send CoA-ACK

send-coa

send CoA-NAK

Post-Auth-Type Reject

send Access-Reject

Post-Auth-Type Challenge

send Access-Challenge

So, instead of the section names being (mostly) randomly named, the names are now consistent. The recv sections receive packets from the network. The send sections send packets back to the network. The second name of the section is the type of the packet that is being received or sent.

For accounting, packets are also processed through an accounting section named after Acct-Status-Type. This process is similar to authenticate for Access-Request packets. The goal here is to allow a common pre-processing of accounting packets in the recv Accounting-Request packet, followed by type-specific processing in accounting %{Acct-Status-Type}. See sites-available/default for examples and more information.

Update Sections

A major difference between v3 and v4 is that update sections are no longer necessary. See the Unlang Syntax pages for more guidance and details.
