sctp: Correctly start rtx timer on new packet transmissions.

2009-02-17T17:46:19Z

[ Upstream commit 6574df9a89f9f7da3a4e5cee7633d430319d3350 ] Commit 62aeaff5ccd96462b7077046357a6d7886175a57 (sctp: Start T3-RTX timer when fast retransmitting lowest TSN) introduced a regression where it was possible to forcibly restart the sctp retransmit timer at the transmission of any new chunk. This resulted in much longer timeout times and sometimes hung sctp connections. Signed-off-by: Vlad Yasevich Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

sctp: Follow security requirement of responding with 1 packet

2008-06-19T23:08:18Z

RFC 4960, Section 11.4. Protection of Non-SCTP-Capable Hosts When an SCTP stack receives a packet containing multiple control or DATA chunks and the processing of the packet requires the sending of multiple chunks in response, the sender of the response chunk(s) MUST NOT send more than one packet. If bundling is supported, multiple response chunks that fit into a single packet MAY be bundled together into one single response packet. If bundling is not supported, then the sender MUST NOT send more than one response chunk and MUST discard all other responses. Note that this rule does NOT apply to a SACK chunk, since a SACK chunk is, in itself, a response to DATA and a SACK does not require a response of more DATA. We implement this by not servicing our outqueue until we reach the end of the packet. This enables maximum bundling. We also identify 'response' chunks and make sure that we only send 1 packet when sending such chunks. Signed-off-by: Vlad Yasevich Signed-off-by: David S. Miller

sctp: Flush the queue only once during fast retransmit.

2008-06-04T19:39:36Z

When fast retransmit is triggered by a sack, we should flush the queue only once so that only 1 retransmit happens. Also, since we could potentially have non-fast-rtx chunks on the retransmit queue, we need make sure any chunks eligable for fast retransmit are sent first during fast retransmission.

sctp: Start T3-RTX timer when fast retransmitting lowest TSN

2008-06-04T19:39:11Z

When we are trying to fast retransmit the lowest outstanding TSN, we need to restart the T3-RTX timer, so that subsequent timeouts will correctly tag all the packets necessary for retransmissions. Signed-off-by: Vlad Yasevich Tested-by: Wei Yongjun Signed-off-by: David S. Miller

SCTP: Initialize partial_bytes_acked to 0, when all of the data is acked.

2008-04-17T21:22:18Z

According to RFC4960 7.2.2, When all of the data transmitted by the sender has been acknowledged by the recerver, partial_bytes_acked is initialized to 0. This patch conforms to rfc requirement. Without this fix, cwnd might be error incremented. Signed-off-by: Gui Jianfeng Acked-by: Vlad Yasevich Signed-off-by: David S. Miller

[SCTP]: "list_for_each()" -> "list_for_each_entry()" where appropriate.

2008-04-13T01:54:24Z

Replacing (almost) all invocations of list_for_each() with list_for_each_entry() tightens up the code and allows for the deletion of numerous list iterator variables that are no longer necessary. Signed-off-by: Robert P. J. Day Signed-off-by: Vlad Yasevich Signed-off-by: David S. Miller

[SCTP]: Fix protocol violation when receiving an error lenght INIT-ACK

2008-04-13T01:39:34Z

When receiving an error length INIT-ACK during COOKIE-WAIT, a 0-vtag ABORT will be responsed. This action violates the protocol apparently. This patch achieves the following things. 1 If the INIT-ACK contains all the fixed parameters, use init-tag recorded from INIT-ACK as vtag. 2 If the INIT-ACK doesn't contain all the fixed parameters, just reflect its vtag.
