* MFC r293913:tuexen2016-01-171-2/+16
| | | | | Fail the SCTP_GET_ASSOC_NUMBER and SCTP_GET_ASSOC_ID_LIST socket options for 1-to-1 style sockets as specified in RFC 6458.
* MFC r291904:tuexen2016-01-171-1/+2
| | | | | | | | | Fix the allocation of outgoing streams: * When processing a cookie, use the number of streams announced in the INIT-ACK. * When sending an INIT-ACK for an existing association, use the value from the association, not from the end-point.
* MFC r291376:tuexen2016-01-171-3/+12
| | | | | | When the sending of an SCTP outgoing stream reset request fails, don't report it to the user since all stream have been marked as pending.
* MFC r291141:tuexen2016-01-161-33/+0
| | | | | Fix the handling of IPSec policies in the SCTP stack. At least make sure they are not leaked...
* MFC r291138:tuexen2016-01-161-1/+2
| | | | Clear the so_pcb pointer in case of ipsec_init_policy() fails.
* MFC r291137:tuexen2016-01-161-4/+3
| | | | | | Don't send SHUTDOWN chunk when the association is in a front state and the applications calls shutdown(..., SHUT_WR) or shutdown(..., SHUT_RDWR).
* MFC r291078:tuexen2016-01-161-51/+52
| | | | | Fix a bug where an SCTP association was moved back to SHUTDOWN_SENT state when the user issued a shutdown() call.
* MFC r289570:tuexen2016-01-161-1/+1
| | | | | | | Use __func__ instead of __FUNCTION__. This allows to compile the userland stack without errors using gcc5. Thanks to saghul for makeing me aware and providing the patch.
* MFC r287282:tuexen2016-01-161-6/+1
| | | | | Fix the exporting of SCTP association states to userland. Without this, associations in SHUTDOWN-PENDING were never reported correctly.
* MFC r285837, r285838tuexen2016-01-161-2/+1
| | | | | | | Fix an issue with MAC OS locking and also optimize the case where we are sending back a stream-reset and a sack timer is running, in that case we should just send the SACK. Fix silly syntax error emacs chugged in for me.. gesh.
* MFC r285792:tuexen2016-01-161-12/+64
| | | | | | | | Fix several problems with Stream Reset. 1) We were not handling (or sending) the IN_PROGRESS case if the other side (or our side) was not able to reset (awaiting more data). 2) We would improperly send a stream-reset when we should not. Not waiting until the TSN had been assigned when data was inqueue.
* MFC r284596:tuexen2015-06-221-9/+16
| | | | When setting the primary address, return an error whenever it fails.
* MFC r284515:tuexen2015-06-201-0/+13

* MFC r272750:tuexen2014-10-121-0/+6
| | | | | | | | Ensure that the number of stream reported in srs_number_streams is consistent with the amount of data provided in the SCTP_RESET_STREAMS socket option. Thanks to Peter Bostroem from Google for drawing my attention to this part of the code.
* MFC r271643:tuexen2014-09-181-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Chunk IDs are 8 bit entities, not 16 bit. Thanks to Peter Kasting from Google for drawing my attention to it. MFC r271665: The MTU is handled as a 32-bit entity within the SCTP stack. This was reported by Peter Kasting from Google. MFC r271670: Make a type conversion explicit. When compiling this code on Windows as part of the SCTP userland stack, this fixes a warning reported by Peter Kasting from Google. MFC r271672: Small cleanup which addresses a warning regaring the truncation of a 64-bit entity to a 32-bit entity. This issue was reported by Peter Kasting from Google. MFC r271673: Use a consistent type for the number of HMAC algorithms. This fixes a bug which resulted in a warning on the userland stack, when compiled on Windows. Thanks to Peter Kasting from Google for reporting the issue and provinding a potential fix. MFC r271674: Add a explict cast to silence a warning when building the userland stack on Windows. This issue was reported by Peter Kasting from Google. Approved by: re (kib)
* MFC r270673:tuexen2014-09-181-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Announce SCTP support in the kern.features sysctl variables. MFC r270859: Enable SCTP support. It runs perfectly fine on a Wandboard quad. MFC r271204 with manual intervention: Fix the handling of sysctl variables when used with VIMAGE. While there do some cleanup of the code. MFC r271209: Fix a leak of an address, if the address is scheduled for removal and the stack is torn down. Thanks to Peter Bostroem and Jiayang Liu from Google for reporting the issue. MFC r271219: Use SYSCTL_PROC instead of SYSCTL_VNET_PROC. Suggested by: glebius@ MFC r271221: Use union sctp_sockstore instead of struct sockaddr_storage. This eliminates some warnings when building in userland. Thanks to Patrick Laimbock for reporting this issue. Remove also some unnecessary casts. There should be no functional change. MFC r271228: Address another warnings reported by Patrick Laimbock when compiling in userspace. While there, improve consistency. MFC r271230: Address warnings generated by the clang analyzer. Approved by: re (kib)
* MFC r269945:tuexen2014-08-221-0/+66
| | | | | | | | Add support for the SCTP_PR_STREAM_STATUS and SCTP_PR_ASSOC_STATUS socket options. This includes managing the correspoing stat counters. Add the SCTP_DETAILED_STR_STATS kernel option to control per policy counters on every stream. The default is off and only an aggregated counter is available. This is sufficient for the RTCWeb usecase.
* MFC r269858:tuexen2014-08-221-0/+140
| | | | | Add support for the SCTP_AUTH_SUPPORTED and SCTP_ASCONF_SUPPORTED socket options. Add also a sysctl to control the support of ASCONF.
* MFC r269527:tuexen2014-08-221-3/+59
| | | | | Add support for the SCTP_RECONFIG_SUPPORTED and the corresponding sysctl controlling the negotiation of the RE-CONFIG extension.
* MFC r269481:tuexen2014-08-221-0/+56
| | | | | | Add support for the SCTP_PKTDROP_SUPPORTED socket option and the corresponding sysctl variable. The default is off, since the specification is not an RFC yet.
* MFC r269475:tuexen2014-08-221-0/+56
| | | | | | | Add SCTP socket option SCTP_NRSACK_SUPPORTED to control the NRSACK extension. The default will still be off, since it it not an RFC (yet). Changing the sysctl name will be in a separate commit.
* MFC r269448:tuexen2014-08-221-0/+56
| | | | | | Add support for the SCTP_PR_SUPPORTED socket option as specified in http://tools.ietf.org/html/draft-ietf-tsvwg-sctp-prpolicies Add also a sysctl controlling the default of the end-points.
* MFC r269436, r269445:tuexen2014-08-221-0/+56
| | | | | | | | Cleanup the ECN configuration handling and provide an SCTP socket option for controlling ECN on future associations and get the status on current associations. A simialar pattern will be used for controlling SCTP extensions in upcoming commits.
* MFC r268526:tuexen2014-08-221-2/+2
| | | | Integrate upstream changes.
* MFC r267688:tuexen2014-06-231-21/+20
| | | | | Fix a bug which incorrectly allowed two listening SCTP sockets on the same port bound to the wildcard address.
* MFC r267682:tuexen2014-06-231-3/+3
| | | | | | Fix a bug in the setsockopt()-handling of the SCTP specific option SCTP_PEER_ADDR_THLDS: Use the provided address as intended.
* MFC r267674:tuexen2014-06-231-0/+45
| | | | | | | | | Honor jails for unbound SCTP sockets when selecting source addresses, reporting IP-addresses to the peer during the handshake, adding addresses to the host, reporting the addresses via the sysctl interface (used by netstat, for example) and reporting the addresses to the application via socket options. This issue was reported by Bernd Walter.
* MFC r263237:tuexen2014-06-221-25/+2
| | | | | | | | | | * 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 r259943:tuexen2014-01-071-1/+1
| | | | Address some warnings which showed up on the userland version.
* MFC r256556:tuexen2013-11-211-14/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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@
