* [DCCP]: Rate-limit DCCP-SyncsGerrit Renker2007-10-106-9/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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]: Remove duplicate code for Reset from connected socketGerrit Renker2007-10-101-59/+19
| | | | | | | | | | | | | | | In this patch, duplicated code is removed for the case when a Reset packet is sent from a connected socket. This code duplication is between dccp_make_reset and dccp_transmit_skb, which already contained an (up to now entirely unused) switch statement to fill in the reset code from the DCCP_SKB_CB. The only thing that has been removed is the call to dst_clone(dst), since the queue_xmit functions use sk_dst_cache anyway. I wasn't sure which purpose inet_sk_rebuild_header served, so I left it in.

* [DCCP]: Add Support for Data 1 .. 3 fields of Reset packetsGerrit Renker2007-10-102-9/+19
| | | | | | | | | | | | This adds fields to support the informational Data 1..3 fields of the DCCP-Reset packets (RFC 4340, 5.6), and makes minor cosmetic changes to documentation. Code which fills in these fields follows in subsequent patches, it is primarily used for reporting option-processing and feature-negotiation errors.

* [DCCP]: Add FIXME for send_delayed_ackGerrit Renker2007-10-102-1/+1
| | | | | | | | | | | | | | | | This adds a FIXME to signal that the function dccp_send_delayed_ack is nowhere used in the entire DCCP/CCID code. Using a delayed Ack timer is suggested in 11.3 of RFC 4340, but it has also rather subtle implications for the Ack-Ratio-accounting. CCID2 does not use this (maybe it should). I think leaving the function in is good, in case someone wants to implement this.

* [CCID3]: Move NULL-protection into functionGerrit Renker2007-10-102-31/+24
| | | | | | | | | | | | | | This moves several instances of testing against NULL into the function which is used to de-reference the CCID-private data. Committer note: Made the BUG_ON depend on having CONFIG_IP_DCCP_CCID3_DEBUG, as it is too much to have this on production code. Also made sure that the macro is used only after checking if sk_state is not LISTEN, to make it equivalent to what we had before.

* [DCCP]: Send Reset upon Sync in state REQUESTGerrit Renker2007-10-101-5/+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.)

* [TCP]: Reordered ACK's (old) SACKs not included to discarded MIBIlpo Järvinen2007-10-101-1/+6
| | | | | | | | | | | | | | | | | | | In case of ACK reordering, the SACK block might be valid in it's time but is already obsoleted since we've received another kind of confirmation about arrival of the segments through snd_una advancement of an earlier packet. I didn't bother to build distinguishing of valid and invalid SACK blocks but simply made reordered SACK blocks that are too old always not counted regardless of their "real" validity which could be determined by using the ack field of the reordered packet (won't be significant IMHO). DSACKs can very well be considered useful even in this situation, so won't do any of this for them. Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: David S.

* [DCCP]: Parameter renamingGerrit Renker2007-10-101-4/+6
| | | | | | | | | | | | | | | | The parameter `seq' of dccp_send_sync() is in fact an acknowledgement number and not a sequence number - thus renamed by this patch into `ackno'. Secondly, a `critical' warning is added when a Sync/SyncAck could not be sent. Sanity: I have checked all other functions that are called in dccp_transmit_skb, there are no clashes with the use of dccpd_ack_seq; no other function is using this slot at the same time.

* [DCCP]: Fix Reset/Sync-Flood BugGerrit Renker2007-10-101-3/+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 Renker2007-10-103-34/+19
| | | | | | | | | | | | | | | | | | | 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).

* [DCCP]: Reuse ktime_get_real() calls againGerrit Renker2007-10-101-23/+16
| | | | | | | | | | | | | | | | | | | | This patch reduces the number of timestamps taken in the receive path for each packet. The ccid3_hc_tx_update_x() routine is called in * the receive path for each CCID3-controlled packet * for the nofeedback timer (if no feedback arrives during 4 RTT) Currently, when there is no loss, each packet gets timestamped twice. The patch resolves this by recycling the first timestamp taken on packet reception for RTT sampling. When the no_feedback_timer() is called, then the timestamp argument is simply set to NULL - so that ccid3_hc_tx_update_x() takes care of the logic.

* [NET_SCHED]: explict hold dev tx lockJamal Hadi Salim2007-10-101-17/+2
| | | | | | | | | | | | | | | | | For N cpus, with full throttle traffic on all N CPUs, funneling traffic to the same ethernet device, the devices queue lock is contended by all N CPUs constantly. The TX lock is only contended by a max of 2 CPUS. In the current mode of operation, after all the work of entering the dequeue region, we may endup aborting the path if we are unable to get the tx lock and go back to contend for the queue lock. As N goes up, this gets worse. The changes in this patch result in a small increase in performance with a 4CPU (2xdual-core) with no irq binding. Both e1000 and tg3 showed similar behavior; Signed-off-by: Jamal Hadi Salim <hadi@cyberus.ca> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NET]: Dynamically allocate the loopback device, part 2.Daniel Lezcano2007-10-101-28/+44
| | | | | | | | | | | | Doing this makes loopback.c a better example of how to do a simple network device, and it removes the special case single static allocation of a struct net_device, hopefully making maintenance easier.
