| * | ike-sa-manager: Make sure the message ID of initial messages is 0 | Tobias Brunner | 2015-03-04 | 1 | -1/+2 |
| | | | | | | | | | | | | | | | | | | It is mandated by the RFCs and it is expected by the task managers. Initial messages with invalid MID will be treated like regular messages, so no IKE_SA will be created for them. Instead, if the responder SPI is 0 no SA will be found and the message is rejected with ALERT_INVALID_IKE_SPI. If an SPI is set and we do find an SA, then we either ignore the message because the MID is unexpected, or because we don't allow initial messages on established connections. There is one exception, though, if an attacker can slip in an IKE_SA_INIT with both SPIs set before the client's IKE_AUTH is handled by the server, it does get processed (see next commit).

| * | ikev2: Don't adopt any CHILD_SA during make-before-break reauthentication | Martin Willi | 2015-03-04 | 1 | -1/+2 |
| | | | | | | | | | | While the comment is rather clear that we should not adopt live CHILD_SAs during reauthentication in IKEv2, the code does nonetheless. Add an additional version check to fix reauthentication if the reauth responder has a replace uniqueids policy. Fixes #871. | ||||
| * | ike-sa-manager: Use IKEv1 uniqueness reauthentication detection for IKEv2, too | Martin Willi | 2015-02-20 | 1 | -12/+8 |

| * | ike: Do not cache MID of IKEv2 fragments | Tobias Brunner | 2014-10-10 | 1 | -2/+3 |
| | | | | | | This fails if there are unencrypted payloads before an encrypted fragment payload in the first fragment. | ||||
| * | ike-sa-manager: Use transient hasher for IKE_SA_INIT hash calculation | Christophe Gouault | 2014-08-25 | 1 | -32/+11 |
| | | | | | | | | | | | | | | | | | To check if a received IKE_SA_INIT request is a new request or a retransmit, charon maintains hashes of the pending IKE_SA_INIT exchanges. However, the hash calculation is not reentrant because a single hasher is used for the whole IKE SA manager. It leads to bogus calculations under high load and hence dropped messages on responder (IkeInInvalidSpi incremented). Don't share a single hasher in the IKE SA manager, create a transient one whenever a message must be hashed. Signed-off-by: Christophe Gouault <christophe.gouault@6wind.com> | ||||
| * | payload: Use common prefixes for all payload type identifiers | Martin Willi | 2014-06-04 | 1 | -2/+2 |
| | | | | | | The old identifiers did not use a proper namespace and often clashed with other defines. | ||||
| * | ike-sa-manager: Improve scalability of half-open IKE_SA checking | Tobias Brunner | 2014-04-24 | 1 | -7/+8 |
| | | | | | | | | | | | | | | | | This patch is based on one by Christoph Gouault. Currently, to count the total number of half_open IKE_SAs, get_half_open_count sums up the count of each segment in the SA hash table (acquiring a lock for each segment). This procedure does not scale well when the number of segments increases, as the method is called for each new negotiation. Instead, lets maintain a global atomic counter. This optimization allows the use of big values for charon.ikesa_table_size and charon.ikesa_table_segments. | ||||

| * | ikev1: Accept reauthentication attempts with a keep unique policy from same host | Martin Willi | 2013-09-30 | 1 | -6/+17 |
| | | | | | | | | When we have a "keep" unique policy in place, we have to be less strict in rejecting Main/Aggressive Modes to enforce it. If the host/port equals to that of an existing ISAKMP SA, we assume it is a reauthentication attempt and accept the new SA (to replace the old). | ||||
| * | ikev1: Delay a potential delete for a duplicate IKE_SA having a replace policy | Martin Willi | 2013-09-30 | 1 | -8/+29 |
| | | | | | | | | | | Sending a DELETE for the replaced SA immediately is problematic during reauthentication, as the peer might have associated the Quick Modes to the old SA, and also delete them. With this change the delete for the old ISAKMP SA is usually omitted, as it is gets implicitly deleted by the reauth. | ||||
| * | Merge branch 'ikev1-rekeying' | Martin Willi | 2013-03-01 | 1 | -0/+21 |
| |\ | | | | | | | | | Migrates Quick Modes to the new Main Mode if an IKEv1 reauthentication replaces the old Main Mode having a uniqueids=replace policy. | ||||
| | * | When detecting a duplicate IKEv1 SA, adopt children, as it might be a rekeying | Martin Willi | 2013-02-20 | 1 | -0/+21 |

| * | | Merge branch 'ikev1-mm-retransmits' | Martin Willi | 2013-03-01 | 1 | -26/+28 |
| |\ \ | | | | | | | | | | | | | | | | Fixes retransmit of the last Main Mode or IKE_AUTH message, and correctly queues Main Mode messages when processing of the last message is still in progress. | ||||
| | * | | For IKEv1 Main Mode, use message hash to detect early retransmissions | Martin Willi | 2013-02-25 | 1 | -10/+23 |
| | | | | | | | | | | | | | | | | As the message ID is zero in all Main Mode messages, it can't be used to detect if we are already processing a given message. | ||||
| | * | | Use INIT macro to initialize IKE_SA manager entries | Martin Willi | 2013-02-25 | 1 | -17/+6 |

| * / | Trigger an updown event when destroying an IKE_SA based on INITIAL_CONTACT | Tobias Brunner | 2013-02-28 | 1 | -0/+1 |
| |/ | | | | | In other cases (i.e. when functions return DESTROY_ME) the event should already be triggered, but not in this forced situation. | ||||
| * | Include source port in init hash for fragmented messages | Tobias Brunner | 2012-12-24 | 1 | -1/+8 |

| * | Add uniqueids=never to ignore INITIAL_CONTACT notifies | Tobias Brunner | 2012-09-10 | 1 | -1/+1 |
| | | | | | | | With uniqueids=no the daemon still deletes any existing IKE_SA with the same peer if an INITIAL_CONTACT notify is received. With this new option it also ignores these notifies. | ||||
| * | Remove the unused second IKE_SA entry match function argument | Martin Willi | 2012-08-20 | 1 | -4/+4 |
| | | | | | LLVMs clang complains about this parameter, so remove it. | ||||
| * | Include src address in hash of initial message for Main Mode | Tobias Brunner | 2012-08-08 | 1 | -5/+31 |
| | | | | | | | | If two initiators use the same SPI and also use the same SA proposal the hash for the initial message would be exactly the same. For IKEv2 and Aggressive Mode that's not a problem as these messages include random data (Ni, KEi payloads). | ||||

| | | | | | | | This change allows to properly handle retransmits of initial IKE messages when we've already processed them (i.e. our response is now resent immediately). | ||||

| | | | | | | For IKEv1 the previous behavior of always using the initiator's SPI as key is maintained. | ||||
| * | Added separate hashtable for hashes of initial IKE messages. | Tobias Brunner | 2012-03-20 | 1 | -64/+139 |
| | | | | | This does not require us to do a lookup for an SA by SPI first. | ||||
