* [DCCP]: Rate-limit DCCP-SyncsGerrit Renker2007-10-111-9/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements a SHOULD from RFC 4340, 7.5.4: "To protect against denial-of-service attacks, DCCP implementations SHOULD impose a rate limit on DCCP-Syncs sent in response to sequence-invalid packets, such as not more than eight DCCP-Syncs per second." The rate-limit is maintained on a per-socket basis. This is a more stringent policy than enforcing the rate-limit on a per-source-address basis and protects against attacks with forged source addresses. Moreover, the mechanism is deliberately kept simple. In contrast to xrlim_allow(), bursts of Sync packets in reply to sequence-invalid packets are not supported. This foils such attacks where the receipt of a Sync triggers further sequence-invalid packets. (I have tested this mechanism against xrlim_allow algorithm for Syncs, permitting bursts just increases the problems.) In order to keep flexibility, the timeout parameter can be set via sysctl; and the whole mechanism can even be disabled (which is however not recommended). The algorithm in this patch has been improved with regard to wrapping issues thanks to a suggestion by Arnaldo. Commiter note: Rate limited the step 6 DCCP_WARN too, as it says we're sending a sync.

* [DCCP]: Send Reset upon Sync in state REQUESTGerrit Renker2007-10-111-5/+3
| | | | | | | | | | | | | | | | | | This fixes the code to correspond to RFC 4340, 7.5.4, which states the exception that a Sync received in state REQUEST generates a Reset (not a SyncAck). To achieve this, only a small change is required. Since dccp_rcv_request_sent_state_process() already uses the correct Reset Code number 4 ("Packet Error"), we only need to shift the if-statement a few lines further down. (To test this case: replace DCCP_PKT_RESPONSE with DCCP_PKT_SYNC in dccp_make_response.)

* [DCCP]: Fix Reset/Sync-Flood BugGerrit Renker2007-10-111-3/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This updates sequence number checking with regard to RFC 4340, 7.5.4. Missing in the code was an exception for sequence-invalid Reset packets, which get a Sync acknowledging GSR, instead of (as usual) P.seqno. This can lead to an oscillating ping-pong flood of Reset packets. In fact, it has been observed on the wire as follows: 1. client establishes connection to server; 2. before server can write to client, client crashes without notifying the server (NB: now no longer possible due to ABORT function); 3. server sends DCCP-Data packet (has no ackno); 4. client generates Reset "No Connection", seqno=0, increments seqno; 5. server replies with Sync, using ackno = P.seqno; 6. client generates Reset "No Connection" with seqno = ackno + 1; 7. goto (5). The difference is that now in (5) the server uses GSR. This causes the Reset sent by the client in (6) to become sequence-valid, so that in (7) the vicious circle is broken; the Reset is then enqueued and causes the socket to enter TIMEWAIT state.

* [DCCP]: Simplify interface of dccp_sample_rttGerrit Renker2007-10-111-29/+15
| | | | | | | | | | | | | | | | | | | The third parameter of dccp_sample_rtt now becomes useless and is removed. Also combined the subtraction of the timestamp echo and the elapsed time. This is safe, since (a) presence of timestamp echo is tested first and (b) elapsed time is either present and non-zero or it is not set and equals 0 due to the memset in dccp_parse_options. To avoid measuring option-processing time, the timestamp for measuring the initial Request/Response RTT sample is taken directly when the function is called (the Linux implementation always adds a timestamp on the Request, so there is no loss in doing this).

| | | | | | | | | | | | | | A recurring problem, in particular in the CCID code, is that RTT samples from packets with timestamp echo and elapsed time options need to be taken. This service is provided via a new function dccp_sample_rtt in this patch. Furthermore, to protect against `insane' RTT samples, the sampled value is bounded between 100 microseconds and 4 seconds - for which u32 is sufficient.

* [DCCP]: Remove ambiguity in the way before48 is usedGerrit Renker2007-04-261-2/+4
| | | | | | | | | | | | | | | | | This removes two ambiguities in employing the new definition of before48, following the analysis on http://www.mail-archive.com/dccp@vger.kernel.org/msg01295.html (1) Updating GSR when P.seqno >= S.SWL With the old definition we did not update when P.seqno and S.SWL are 2^47 apart. To ensure the same behaviour as with the old definition, this is replaced with the equivalent condition dccp_delta_seqno(S.SWL, P.seqno) >= 0 (2) Sending SYNC when P.seqno >= S.OSR Here it is debatable whether the new definition causes an ambiguity: the case is similar to (1); and to have consistency with the case (1), we use the equivalent condition dccp_delta_seqno(S.OSR, P.seqno) >= 0 Detailed Justification
* [DCCP]: Revert patch which disables bidirectional modeGerrit Renker2007-03-081-17/+4
| | | | | | | | | | | | | | | | This reverts an earlier patch which disabled bidirectional mode, meaning that a listening (passive) socket was not allowed to write to the other (active) end of the connection. This mode had been disabled when there were problems with CCID3, but it imposes a constraint on socket programming and thus hinders deployment. A change is included to ignore RX feedback received by the TX CCID3 module. Many thanks to Andre Noll for pointing out this issue.

* [DCCP]: Only deliver to the CCID rx side in chargeGerrit Renker2006-12-111-4/+17
| | | | | | | | | | | | | | | | | | | | | | | This is an optimisation to reduce CPU load. The received feedback is now only directed to the active CCID component, without requiring processing also by the inactive one. As a consequence, a similar test in ccid3.c is now redundant and is also removed. Justification: Currently DCCP works as a unidirectional service, i.e. a listening server is not at the same time a connecting client. As far as I can see, several modifications are necessary until that becomes possible. At the present time, received feedback is both fed to the rx/tx CCID modules. In unidirectional service, only one of these is active at any one time.

* [DCCP]: Simplified conditions due to use of enum:8 statesGerrit Renker2006-12-031-14/+11
| | | | | | | | | | | | | | | | | | | | | | This reaps the benefit of the earlier patch, which changed the type of CCID 3 states to use enums, in that many conditions are now simplified and the number of possible (unexpected) values is greatly reduced. In a few instances, this also allowed to simplify pre-conditions; where care has been taken to retain logical equivalence. [DCCP]: Introduce a consistent BUG/WARN message scheme This refines the existing set of DCCP messages so that * BUG(), BUG_ON(), WARN_ON() have meaningful DCCP-specific counterparts * DCCP_CRIT (for severe warnings) is not rate-limited * DCCP_WARN() is introduced as rate-limited wrapper Using these allows a faster and cleaner transition to their original counterparts once the code has matured into a full DCCP implementation.

* [DCCP] CCID: Improve CCID infrastructureArnaldo Carvalho de Melo2006-03-211-8/+0
| | | | | | | | | | | | | | | | | | | 1. No need for ->ccid_init nor ->ccid_exit, this is what module_{init,exit} does and anynways neither ccid2 nor ccid3 were using it. 2. Rename struct ccid to struct ccid_operations and introduce struct ccid with a pointer to ccid_operations and rigth after it the rx or tx private state. 3. Remove the pointer to the state of the half connections from struct dccp_sock, now its derived thru ccid_priv() from the ccid pointer. Now we also can implement the setsockopt for changing the CCID easily as no ccid init routines can affect struct dccp_sock in any way that prevents other CCIDs from working if a CCID switch operation is asked by apps.

* [DCCP]: Do not process a packet twice when it's not in state DCCP_OPEN.Andrea Bittau2006-01-031-22/+34
| | | | | | | | | | | | | | | | | | | | | | | | When packets are received, the connection is either in DCCP_OPEN [fast-path] or it isn't. If it's not [e.g. DCCP_PARTOPEN] upper layers will perform sanity checks and parse options. If it is in DCCP_OPEN, dccp_rcv_established() will do it. It is important not to re-parse options in dccp_rcv_established() when it is not called from the fast-path. Else, fore example, the ack vector will be added twice and the CCID will see the packet twice. The solution is to always enfore sanity checks from the upper layers. When packets arrive in the fast-path, sanity checks will be performed before calling dccp_rcv_established(). Note(acme): I rewrote the patch to achieve the same result but keeping dccp_rcv_established with the previous semantics and having it split into __dccp_rcv_established, that doesn't does do any sanity check, code in state != DCCP_OPEN use this lighter version as they already do the sanity checks.

| | | | | | | | | | | | | | As DCCP needs to be called in the same spots. Now we have a member in inet_sock (is_icsk), set at sock creation time from struct inet_protosw->flags (if INET_PROTOSW_ICSK is set, like for TCP and DCCP) to see if a struct sock instance is a inet_connection_sock for places like the ones in ip_sockglue.c (v4 and v6) where we previously were looking if sk_type was SOCK_STREAM, that is insufficient because we now use the same code for DCCP, that has sk_type SOCK_DCCP.
