2013-04-22l2tp: Check for connection limits upon session creation requestsGuillaume Nault
Since multiple sessions may be created in each tunnel, a client may bypass the connlimit module by creating many sessions in an existing tunnel (connlimit is only used upon reception of SCCRQ messages). This patch adds connlimit checks when handling session creation requests (ICRQ and OCRQ) so that connection limits get enforced in every case. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>

2013-04-17l2tp: Handle 64 bits attributesGuillaume Nault
Define l2tp_packet_add_int64() to create attributes of 64 bits long integers. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-04-17l2tp: Use random length Challenge AVPGuillaume Nault
Set Challenge attribute using a random length so that its size can't be guessed when hide-avps is on. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-04-17l2tp: Full hidden AVPs supportGuillaume Nault
Add option "hide-avps" in the "l2tp" section for hiding attributes sent to peer. This same option is also made available on accel-ppp's command line interface: accel-ppp# tunnel create tunnel peer-addr 192.0.2.1 hide-avps 1 Attribute hiding is performed upon attribute creation (in the l2tp_packet_add_*() functions family) rather than upon packet sending. This avoid running the cipher for every retransmission; the counterpart is that l2tp_packet_print() can't dump original attributes of hidden AVPs. Currently, only one random vector is used for all hidden AVPs in a packet. This is easily extensible though, as the 'last_RV' field in struct l2tp_packet_t may be overridden to use new vectors for next AVPs. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-04-17utils: Add random buffer generation functionGuillaume Nault
Define and export the u_randbuf() function that fills a buffer with random data. Convert L2TP's challenge generation code for using it. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-04-17l2tp: Handle incoming hidden AVPsGuillaume Nault
Decode hidden AVPs on reception. This is transparent for functions in l2tp.c (except for the presence of the Random Vector AVP). Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-04-17l2tp: Store length of conf_secretGuillaume Nault
Secret length is used quite often especially when handling hidden AVPs. Store conf_secret length together with conf_secret to avoid calling strlen(conf_secret) every time. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-04-17l2tp: Fix endianness of 64 bits AVPs (reception)Guillaume Nault
Received attributes of type ATTR_TYPE_INT64 are transferred to upper layer in network byte order while any other integer type uses host byte order. This patch converts int64 values to host byte order so that they can be used like other integer types. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-04-17l2tp: Fix double string AVP copyGuillaume Nault
When adding a string AVP to an L2TP packet, the attribute value is allocated and set using strdup(). There's no need to memcpy() it again afterwards. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-04-15ipoe: fixed ses->client_id and ses->relay_agent initializationDmitry Kozlov
2013-04-11radius: implemented default-realm optionKozlov Dmitry
2013-03-28l2tp: Add general packet processing log messagesGuillaume Nault
Use "info2" log messages to inform about packets sent or processed. For HELLO and ZLB messages, the log level is set to "debug" as these are transmitted quite often and don't bring much information (this same logging policy is used for logging packets when conf_verbose is on). Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-03-28l2tp: Log packet retransmission informationGuillaume Nault
Log message for any packet retransmission action using log_tunnel() and level "info2". Remove l2tp_conn_log() since it is no longer used. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-03-28l2tp: Log all discarded messages in the same wayGuillaume Nault
Add a log message (warn level) for any discarded message type. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-03-28l2tp: Log session establishment/disconnection informationGuillaume Nault
Use info1 messages to log information about main session establishment and disconnection steps. These messages are: * establishment requests and their origin (CLI, ICRQ or OCRQ) * establishment confirmation (when session is really established) * PPP establishment * disconnection requests and their reason Other information of interest use info2. These include: * Peer Session ID setting * Session internal structure freeing Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-03-28l2tp: Log tunnel establishment/disconnection informationGuillaume Nault
Use info1 messages to log information about main tunnel establishment and disconnection steps. These messages are: * establishment requests and their origin (CLI or SCCRQ) * establishment confirmation (when tunnel is really established) * disconnection requests and their reason Other information of interest use info2. These include: * Peer port update * Peer Tunnel ID setting * Tunnel internal structure freeing Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-03-28l2tp: Use consistent packet logging policyGuillaume Nault
Adapt packet logging policy to make it consistent across L2TP packet handling functions: * Don't log messages if conf_verbose is off. * Log HELLO and ZLB messages with log_debug and use log_info2 for any other message type. * Log retransmissions with log_info2, no matter the message type. * Log outgoing messages right before sending them. * Log incoming messages right before analysing their message type. This unifies the way l2tp_conn_read() and l2tp_udp_read() log incoming messages. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-03-28l2tp: Handle WEN messagesGuillaume Nault
Implement minimal WEN messages processing, so that they get properly acknowledged. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-03-28l2tp: Avoid tunnel destruction when possibleGuillaume Nault
Handle incomming messages differently depending on their Message Type: * Close tunnel only when handling tunnel establishment messages fails (SCCRP and SCCCN) and everytime a StopCCN is received. * Never close tunnel after reception of HELLO, SLI or session establishment messages (ICRQ and OCRQ). * Ignore messages with invalid first attribute type. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-03-28l2tp: Parse incoming CDN messagesGuillaume Nault
Interpret AVPs present in CDN to provide user with better diagnostic. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-03-28l2tp: Handle allocation failure in l2tp_session_connect()Guillaume Nault
Allocate PPP channel name using the string size to be stored and check for allocation failure. Use two snprintf() and a _malloc() instead of asprintf() so that allocated memory will be visible by memdebug. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-03-28l2tp: Use consistent return values for l2tp_{recv, send}*()Guillaume Nault
In all reception or sending functions, return 0 on success or if incomming message has been ignored (l2tp_recv_*() only). Return -1 upon any processing error. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-03-28l2tp: Remove some redundant log messagesGuillaume Nault
There is no need to warn about missing Challenge when handling SCCRQ comming from a host for which a secret exists: this will be done automatically upon SCCRP generation (by l2tp_tunnel_genchallresp()). Using the log message from l2tp_tunnel_genchallresp() has the advantage of working for missing Challenge AVPs in both SCCRQ and SCCRP messages. This patch also removes a redundant log message in l2tp_session_recv() when handling unknown message types. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
2013-03-28l2tp: Simplify some function call sequencesGuillaume Nault
* Avoid retrieving tunnel and session contexts manually; use l2tp_{tunnel,session}_self() instead. * Use l2tp_session_disconnect() instead of using an l2tp_send_CDN(); l2tp_session_free() sequence. Signed-off-by: Guillaume Nault <g.nault@alphalink.fr>
