* (rs_packet_destroy): Free unconditionally.Linus Nordberg2011-03-141-7/+6
|
* Remove struct rs_attr and all use of it.Linus Nordberg2011-03-141-18/+15
| | | | | | | A new API for attributes will be added once we've decided how to deal with RADIUS packets internally. For now, removing the half baked wrapping seems more sensible than trying to free rs_attr objects and their VALUE_PAIR's.
* Get UDP working.Linus Nordberg2011-03-091-2/+0
| | | | | | | | | | | | | | | | For UDP, activate retransmit timer before receiving rather than sending makes the event loop break nicely after sending a message (which is important for blocking mode). Not quite sure that this is really accurate wrt to retransmission timing though but it should do for now. For UDP, set the user_data member for the read callback in rs_conn_receive_packet -- the one from udp_init() doesn't do much good now. For UDP, implement receiving message. Add compat_recv().
* Don't add Message-Authenticator more than once.Linus Nordberg2011-03-091-2/+8
| | | | | Retransmiting the packet showed that we added another Message-Authenticator attribute every time we sent it.
* Formatting changes.Linus Nordberg2011-03-091-0/+1

* Add retransmission timer support (UDP).Linus Nordberg2011-03-091-2/+4
|
* Move verification of response packets up to a level where it makes sense.Linus Nordberg2011-03-071-3/+36
| | | | | | | | | | | | | | | | | | | | | Replace the user_dispatch_flag on connections with conn_user_dispatch_p(). Remove the 'original' member from packet and instead have an upper layer verify. Rename packet valid_flag --> received_flag to reflect that we don't verify. Move _close_conn() --> conn_close(). Move packet flags into a single unsigned int, for portability. (_read_packet): Don't verify packet. (rs_conn_receive_packet): Don't touch PKT_OUT if there isn't a packet. (rs_conn_receive_packet): Verify packet using packet_verify_response().
* Restructure code, moving most code out of packet.cLinus Nordberg2011-03-061-775/+7

| | | | | Remove RSE_SOME_ERROR. rs_tls_init: Push SSL error stack on libradsec error stack.
* Rename relevant functions to reflect authn as opposed to authz.Linus Nordberg2011-02-281-3/+3
| | | | Also add a "bare" create request function.
* Time out on connect and break event loop on errors.Linus Nordberg2011-02-251-0/+48
|
* Get rid of loopbreak as a mean for signalling successful packet handling.Linus Nordberg2011-02-251-29/+14
| | | | | | | | | | | | | In blocking mode, breaking the event loop with loopbreak will probably be needed for exceptions like timeout so we shouldn't use it for breaking the loop and signalling success. In the user callbaks used in blocking mode (_rcb and _wcb), disable read and write events on the event buffer. This will stop the loop. Also, set a flag in the packet struct to signal success. In the "low level callbacks" (_read_cb and _write_cb), enable read or write, accordingly.
* Config file changes and small API changes.Linus Nordberg2011-02-241-61/+105
| | | | | | | | 'timeout' and 'tries' move from 'server' stanza to top. 'tries' is now 'retries'. Moving around in internal data structs, making struct peer strictly config. Bug fixes in configuration code. Adding some more cleanup code, freeing allocated memory (still not done!).
* Report SSL errors with error string rather than an integer.Linus Nordberg2011-02-201-1/+1
|
* Improve protocol robustness and invoke user callbacks.Linus Nordberg2011-02-191-142/+270
| | | | | | | | | | | | All aborts are removed, as well as all asserts which aren't programming errors. When an invalid packet is received, the connection is closed, as per draft-ietf-radext-tcp-transport-08 (2.6.4). Use new rs_debug() macro rather than fprintf() for debug printouts. Coding style overhaul.

|
* Don't consume sent packets.Linus Nordberg2011-02-041-2/+0
| | | | | | | A sent packet is a fine thing to have when you're verifying the Response Authenticator. We could solve this by having an upper layer saving only the Request Authenticator somewhere instead the whole packet and we might just do that at some point which is not now.
