* MFC r264838:tuexen2014-06-221-1/+15
| | | | | | Don't free an mbuf twice. This only happens in very rare error cases where the peer sends illegal sequencing information in DATA chunks for an existing association.
* MFC r264704:tuexen2014-06-221-1/+36
| | | | | Add consistency checks to ensure that fragments of a user message have the same U-bit.
* MFC r264682:tuexen2014-06-221-1/+1
| | | | Use consistently debug output instead of an unconditional printf.
* MFC r264679:tuexen2014-06-221-1/+16
| | | | | Send the correct error cause, when a DATA chunk with no user data is received. This bug was reported by Irene Ruengeler.
* MFC r263237:tuexen2014-06-221-491/+153
| | | | | | | | | | * Provide information in error causes in ASCII instead of proprietary binary format. * Add support for a diagnostic information error cause. The code is sysctlable and the default is 0, which means it is not sent. This is joint work with rrs@.
* MFC r256556:tuexen2013-11-211-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove a buggy comparision when setting manually the path MTU. After fixing, the comparision would have become redundant. Thanks to Andrew Galante for reporting the issue. MFC r257272: Fix compilation if SCTP_DONT_DO_PRIVADDR_SCOPE is defined. The issue was reported by Andrew Galante. MFC r257274: Fix the value of *optlen when calling getsockopt() for SCTP_REMOTE_UDP_ENCAPS_PORT. This issue was reported by Andrew Galante. MFC r257359: Terminate a debug output with a \n. MFC r257555: Changes from upstream to improve compilation when INET or INET6 or none of them is defined. MFC r257574: Unlock the lock before destroying it. This issue was reported by Andrew Galante. MFC r257800: Use htons()/ntohs() appropriately. These issues were reported by Andrew Galante. MFC r257803: Make sure that we don't try to build an ASCONF-ACK chunk larger than what fits in the the mbuf cluster. This issue was reported by Andrew Galante. MFC r257804: Get rid of the artification limitation enforced by SCTP_AUTH_RANDOM_SIZE_MAX. This was suggested by Andrew Galante. MFC r258221: Cleanups which result in fixes which have been made upstream and where partially suggested by Andrew Galante. There is no functional change in FreeBSD. MFC r258224: When determining if an address belongs to an stcb, take the address family into account for wildcard bound endpoints. MFC r258228: Remove a stray write operation. MFC r258235: Use SCTP_PR_SCTP_TTL when the user provides a positive timetolive in sctp_sendmsg(). Approved by: re@

* Improvements to CC modules:rrs2011-02-261-0/+26
| | | | | | | | | | | 1) Add four new points that allow you to get more information to cc algo's 2) Fix the case where user changes module on a existing TCB, in such a case, the initialization module needs to be called on all nets. 3) Move htcp_cc structure to a union that other modules can use. 4) Add 5th point for get/set socket options for cc_module specific options MFC after: 2 months
* 1) Typo correction in comments and one spacing change.rrs2011-02-051-0/+2

* 1) Allow a chunk to track the cwnd it was at when sent.rrs2011-02-021-8/+12
| | | | | | | | | | | | | | | | | | | 2) Add separate max-bursts for retransmit and hb. These are set to sysctlable values but not settable via the socket api. This makes sure we don't blast out HB's or fast-retransmits. 3) Determine on the first data transmission on a net if its local-lan (by being under or over a RTT). This can later be used to think about different algorithms based on locallan vs big-i (experimental) 4) The cwnd should NOT be allowed to grow when an ECNEcho is seen (TCP has this same bug). We fix this in SCTP so an ECNe being seen prevents an advance of cwnd. 5) CWR's should not be sent multiple times to the same network, instead just updating the TSN being transmitted if needed. MFC after: 1 Month
* More ECN fixes:rrs2011-01-311-182/+5
| | | | | | | | | | | 1) We now remove ECN-Nonce since it will no longer continue as a I-D 2) Eliminate last_tsn_echo, this tied us to an assoc not the net and thus we were not doing m-homing on the ECN-Echo senders side right. 3) Increment the count going out even if the TSN in lower in the pending ECN-Echo, this way the receiver knows exactly how many packets were marked even with network re-ordering 4) Fix so we DO NOT stop doing delayed sack if a ECN Echo is in queue MFC after: 1 month
* Fixes to ECN in SCTP.rrs2011-01-291-0/+8
| | | | | | | | | | | | | 1) ECN was on an association basis, this is incorrect and will not work with CMT or for that matter if the user is sending to multiple addresses. This commit makes ECN on a per path basis. 2) Adopt the new format for the ECN internet draft. This also maintains compatability with old format chunks as well. 3) Keep track of the real time of a RTT down to micro seconds. For some future conditional features (for like a data center this is good information to have). MFC after: 1 month
