I trace the problem in to 2 problem: 1) in sctp_grub_through_socket_buffer(), after we moved some data into new socket, we try to "re-position" the sctp_vtag_last. We are doing: if (tcb->sctp_ep->sctp_vtag_last == asoc->my_vtag) This didn't seems right to me. The tcb->sctp_ep is already pointed to new_inp from sctp_get_peeloff(), it's sctp_vtag_last usually is 0, and since we just moved a lot of asoc->my_vtag buffer into new socket, tcb->sctp_ep->sctp_vtag_last should just assigned to asoc->my_vtag. I changed these to: if (new_sb->sb_mb) tcb->sctp_ep->sctp_vtag_last = asoc->my_vtag; if (inp->sctp_vtag_last == asoc->my_vtag) { inp->sctp_vtag_last = 0; /* scan the old_sb->sb_mb, find the correct vtag, and assign it to inp->sctp_vtag_last. */ } 2) in sctp_usrreq() we call sctp_usr_recvd() with flag = 0. this makes sctp_usr_recvd()'s code for re-position sctp_vtag_last won't be executed. (it depends on flag & MSG_EOR). Change it to: sctp_usr_recvd(so, (int)nam); With fix 1) and 2), the peeloff start runing better Xiaodan Tang R&D QNX Software Systems Ltd.

I am trying to see if there is any way we can reserve an external port. Any suggestions would be appreciated. Does the reference implementation provided with Randall's book provide the ADDIP/DELIP extension? The below scenario seems very possible in the wireless world. I wonder if Mobile SCTP covers this scenario? I am having some problems installing it on Linux Redhat 8.0. "gmake" or "make" returns No targets. Stop. Is some configuration necessary? Thank you.

First, it inverts the normal challenge of a NAT box. Typically a single NAT box making multiple internal hosts appear to be part of a single virtual host. Here two distinct NAT boxes are representing the same host, further they want the outside world to know they are the same host even with different IP addresses. Some specific challenges: - Can NAT Y be guaranteed to use the same port as NAT X? Normally selection of external ports on a NAT is not deterministic. Typically, the best that is offered is to use the port supplied by the internal host -- as long as it is not already in use. If 172.7 is talking to HOST C via NAT Y, the desired port may already be assigned to it. Unless NAT Y is doing 1 to 1 matching of internal addresses with external addresses this will be a problem. - Can the public address via NAT Y be known without first establishing the association in a way visible to NAT Y? I am assuming that NAT Y has support for SCTP, but that the support is basically a translation of TCP primitives. That is, the NAT was adapted to recognize new methods of spotting a new "connection" and its termination, and probably that there is a new port space. But I would not assume that it did more without being told so in advance. In particular, I would not assume that it would recognize a packet that is part of an association established via NAT X. Ideally, NAT Y would support an interface allowing reservation of an external port. Host A would ask NAT Y to simply create a port mapping for 172.5 port J, and then use the value supplied. Many NATs support this functionality, for the purpose of hosting virtual servers within a firewall. Having made the reservations on both NAT X and Y, the INIT can be sent listing the public addresses in the Address List.

We does check asocid (in sctp_findassociation_ep_asocid()) that it is in range of "highest_tcb" and "lowest_tcb". Other then that, we just used it. It looks dangrous that if the user passin a bogus asocid, and happened to be in range, we could just panic kernel... -xtang ----- Original Message ----- From: Randall Stewart (cisco) To: Xiaodan Tang Cc: Sent: Monday, April 14, 2003 9:54 AM Subject: Re: [Bug Report] running peeloff test over localhost > Xiaodan: > > Thanks for looking in to this..

The memory address is a valid kernel memory address that has been used for an association. Yes I can make up a bogus address inside the range of addresses but it MUST be a useable address. So lets say I have: Addr-1 - 0xc0000100 ---------- . . ------ Addr-2 - 0xc0000200 ------ . . ------ Addr-3 - 0xc00000300 ----- etc up to having used 0xc0000a00 Now the user MUST give an address between the values of 0xc0000100 - 0xc000a00 (where our highest and lowest are). These are valid addresses... they may not be his... so lets say the user makes up not a properly aligned address but instead 0xc0000201 The memory area is completely valid.. maybe belonging to other associations.. maybe sitting in the free pool/zone, the pooling code will cache old allocations .... Now if we examine this memory we CAN NOT get a segmentation fault... the memory IS valid.. reading this is not a problem either.. we are not changing it.. But we are validating it..

If one piece is returned to pool/zone, doesn't the pool allowed to map if off. You seems bating all the OS (kernel) will never unmap their free memory. Another problem is on CPUs like SH4 or ARM, you are not allowed to do unalignment access. So you can't read a 4byte value (a pointer) from a 0xc0000201 address (the address is not on 4 byte boundery). Once you do this (yes, even if you only read), an "Alignment Fault" will be generated.

The idea of sctp_vtag_last is it holds the vtag of the packet currently being read in. So what does this code supposedly do? 1) It first checks that vtag_last... in case a partial read has been done before the sctp_peeloff() was called... if so it pulls the top chain of mbufs... 2) After that check, it then goes through the entire chain looking for matching vtags in the recv'd messages that are on queue. 3) After all are taken we do NOT want to touch vtag_last unless <1> above was true.. i.e. the top of the mbuf chain contained one that was moved. The problem, I think, was NOT the if.. but the loop itself was using m_next to move through the mbuf chain.. this is incorrect.. it should have used m_nextpkt.. this same bug is also in sctp_usrreq.c > >2) in sctp_usrreq() we call sctp_usr_recvd() with flag = 0. > this makes sctp_usr_recvd()'s code for re-position > sctp_vtag_last won't be executed.

You will get random execution based on the address of the mbuf that holds the socket address.. not right I think.. Instead we will need to look at the top of what is left on the recvbuf and then, if it is a m_pkthdr type, set the MSG-EOR falg I will get a patch with this in place..

For the Assoc_id thing, I understand that's a quick hack. After all, I agree there is no "easy & cheap" way to varify the pointer. I applied your patch, retried the peeloff test, this still not work (faild on second pass with check sum error). I believe the problem is at sctp_uerreq.c code: case PRU_RCVD: if( so->so_rcv.sb_mb->m_flags & M_PKTHDR ) /* a full record * was read if the first buf * has a M_PKTHDR on the top. */ error = sctp_usr_recvd(so, MSG_EOR); } else error = sctp_usr_recvd(so, 0); } break; First of all, you want to check so->so_rcv.sb_mb != NULL. Then, if you check the soreceive() (where our sctp_usrreq() is called), I think it moved the first MBUF off the so_rcv, and then called us. That means, it is too late to check the mbuf with M_PKTHDR. Also, if you check soreceive(), you can see it build up the flags according to the information in mbuf it removed, and passed that flags into us as our "nam" paramater... I switched back to pass down the "nam" to sctp_usr_recvd(), and things start to working... I still have question about sctp_grub_through_socket_buffer(). In another email you explained the code as: > 1) It first checks that vtag_last... in case a partial read has been > done before the sctp_peeloff() was called... if so it pulls the top chain > of mbufs... > > 2) After that check, it then goes through the entire chain looking for > matching vtags in the recv'd messages that are on queue. > > 3) After all are taken we do NOT want to touch vtag_last unless <1> > above was true.. i.e. the top of the mbuf chain contained one that was > moved. In 1) we are checking "inp->sctp_vtag_last == asoc->my_vtag", but in 3) we are checking "tcb->sctp_ep->sctp_vtag_last == asoc->my_vtag". The "tcb->sctp_ep" is not the same "inp" in this case, it is the new inp belongs to the new socket that created in sctp_get_peeloff(). So it looks to me it's wrong to repositon "tcb->sctp_ep->sctp_vtag_last". Since it is the new socket, the "tcb->sctp_ep->sctp_vtag_last" should just assigned with assoc->my_vtag (just in case, the user do another sctp_peeloff() on the new peeled off socket) As for inp->sctp_vtag_last, you want to reposition it to the mbufs still left in oldsb->so_rcv. That's what I inteded to do in the code I sent you last time. It is arguable if one need to reposition on inp->sctp_vtag_last, cause after some socket buffer moved to new socket, what left, should always be a FULL packet (M_PKTHDR), where sctp_vtag_last will be initialized if the user did another read on it. If the user do another peeloff() without any read, since the first packet is a M_PKTHDR packet, we should be fine. We probably just want to zero it, in cause after peeloff() there is no mbuf left in old socket. -xtang From owner-extdom.sctp-impl@sj-core-1.cisco.com Wed Apr 16 02:15:56 2003 Received: from ietf-mx (ietf-mx.ietf.org [132.151.6.1]) by ietf.org (8.9.1a/8.9.1a) with ESMTP id CAA05575 for ;

Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Content-Transfer-Encoding: 7bit Randy & all, What are other folks doing for a fragmented message that is only partially acknowledged. For example, a message gets fragmented into 5 chunks and only 3 are acked of the 5, when the association is ABORTed. Now if I read the I-D I would assume that the entire message is returned back as a single SEND_FAILED notification, but I vaguely recall a discussion where either the KAME impl or some other returned the message back up in multiple notifications (though I don't recall whether all fragments got returned, or just the failed fragments). Now, I may be _completely_ misremembering the multiple notifications discussion, but I did want to get clarification on what the application can expect in this scenario. BTW, we (Sridhar Samudrala and myself from IBM) are planning to attend the the June SCTP InterOp. Hope to see everyone there that can attend.

Following scenario: 1) endpoint 1 sends an INIT to endpoint 2 2) endpoint 2 answers with an INIT ACK with several IP address parameters 3) endpoint 1 sends a COOKIE ECHO 4) endpoint 2 does not send a COOKIE ACK 5) after the timer expires endpoint 1 sends again the COOKIE ECHO If endpoint two is not answering again, endpoint 1 will try this Max.Init.Retransmits. Then it reports a failure, enters the closed state and retransmitts the INIT (see Section 5.1.6 of rfc2960) Now, I have the following question: Does this new INIT have to be sent to the same IP address or can it be sent to one of the alternative IP addresses found in the INIT ACK? I didn't find anything in the standard (or did I overlook something?)

It doesn't say that *after* entering the closed state you start again retransmitting the INIT chunk. It says "when retransmitting the INIT", but this is supposed to happen before, not after closing the association. I.e., the association establishment phase is as follows... 1) You send the INIT. 2) If you don't receive the INIT ACK you retransmit the INIT (this is what that text at the end of the section is about). 3) When you receive the INIT ACK, you send the COOKIE ECHO. 4) If you don't receive the COOKIE ACK, you retransmit the COOKIE ECHO. Too many retransmissions at 2) or 4) makes you fail the establishment phase, so you close the association, you report it to the upper user, *and nothing else* (unless the upper user tells you to do so). At this point, Randall's explanation should be obvious for you: since you have erased everything, and you only send again INITs to the same endpoint *if the upper user tells you to do so* (i.e., restarting again the whole process, unrelated to the previous attempt), you can only use the address the upper user provides you. I hope it helped!

However, I would like to introduce myself. I am Mr.Mabaza Kumbu, the son of Dr. Deniel Kumbu, who was murdered few months ago in Zimbabwe as a result of land dispute. Before the death of my father (Dr KUMBU), he had taken me to AMSTERDAM to deposit the sum of Fifteen Million United States dollars (US$15.000,000) in a security company, as he foresaw the looming danger in Zimbabwe. The money in question was deposited in a box as Gemstones to avoid much demurrage from the security company. The proposed amount was meant for the purchase of new machines and chemicals for the farms and establishment of new farms on Swaziland. As you may be aware this land problem came into force when Zimbabwe president Mr. Robert Mugabe Introduced the Land Reformed Act of which my father rich farmers and some black farmers where affected. This resulted to the killing and Mob action by Zimbabwe war veterans and some lunatics in the society, infact, a lot of people were killed because of this Land Reformed act of which my dad was one of the victims. It is against this background that my family and I who are currently staying in Amsterdam decided to transfer my father?s money to a foreign account. Since the Dutch law prohibit a refugee (asylum seeker) to open any account or be involved in any financial transaction. As the eldest son of my father, I am saddled with the responsibility of seeking a genuine foreign account where the money could be transferred . I am faced with the dilemma of investing this amount of money in Holland for the fear of going through the same experience in future since both countries have similar history. Moreover, The Netherlands foreign exchange policy does not allow such investment from asylum seekers. As a businessman, whom I have entrusted my future and my family in his hands, ! I must let you know that this transaction is risk free. If you accept to assist me and my family, all I need you to do for me is to make arrangement and come to AMSTERDAM, THE NETHERLANDS, so that we can open the non-resident account which will aid us in transferring the money into any account you will nominate overseas. This money I intend using for investment. I have options to offer you, first you can choose to have certain percentage of the money for nominating your account for the transaction, or you can go into partnership for a proper profitable investment of the money in your country. Which ever option you choose, feel free to notify me. I have mapped out 5% of this money for all expenses incurred in processing the transaction. If for some reasons you do not prefer a partnership, I am willing to give you 25% of the money while the remaining 70% that is meant for me, will be for the investment in your country. Please, contact me on the above Email or my direct telefoon number 00-31 630-435-542,provide me with your telephone number so we can discuss further and a chance for you to ask me any question you may have in mind, while you maintain the absolute secrecy required in the transaction.please kindly get back to me with your detail contacts.

Host A is on a GPRS network and Host B is on a university network and is assigned a fixed IP. Results using the University of Essen's implementatino were very similar. Host A (private IP 172.18.56.36) towards Host B (fixed IP 137.132.165.205) traceroute returns 9 hops, then about 10 ***, without actually terminating at Host B. However, Host A can ping and ftp Host B. Using the Reference Implementation, Host A: The log /usr/tmp/sctpclient shows an INIT chunk being formulated. Ethereal logs show the INIT chunk being repeatedly sent. Host B: The log /tmp/sctpDeamon does not show anything being received. SCTP associations were previously successfully set up between Host B and another machine internal to Host B's network (172.x.x.x). 1 We feel that the packet should at least arrive at the host, since it should be pure IP routing. Since it's not showing up in the sctpDeamon logs, is there any way to know if it actually arrived? 2. Might there be any SCTP servers we could try to initialise a SCTP connection using our private IP client? 3. Have there been any instances where SCTP has been known to work from behind a NAT? Thank you. Regards, Se-Hsieng
