[Fwd: FreeNSIS 0.6.0 buffer overflow]
by Xiaoming Fu 08 Jul '08

08 Jul '08

-------- Original Message -------- Subject: FreeNSIS 0.6.0 buffer overflow Date: Tue, 8 Jul 2008 13:36:18 +0200 From: Nuutti Varis <nvaris(a)cs.helsinki.fi> To: Fu, Xiaoming <fu(a)cs.uni-goettingen.de> Greetings, There's a rather limiting issue in the FreeNSIS 0.6.0 release, causing a crash in GIST. In file SocketEventHandler.cpp, the SocketEventHandler::recvCModeMessage method seems to presume that the incoming data from a C-mode connection is always a maximum of 512 bytes, as indicated by line 157 in the source code. Additionally, the length of the buffer is not checked in the socket instance's recvMsg method (seems to use the regular recvMsg method of Socket.cpp in the case of TCP). This essentially causes an issue, where relatively small NSLPData (seems to be at minimum 468 bytes) objects cause memory corruption, due to buffer overflow in recvMsg method, and consequently, a crash in GIST. The previous version (0.5.1-dev) handled C-mode sockets differently, and as such, do not crash due to a larger buffer that is allocated in the SocketEventHandler::recvCModeMessage method. Best Regards, Nuutti Varis

RE: [Nsis_imp] Fundamental questions about QoS NSLP
by Christian Dickmann 09 May '08

09 May '08

Hi, I am not the expert on the QoS NSLP, but from reading the log I have the feeling that everything is working as expected. See inline ... > First of all, I would like to know what's the meaning of "Received > response: 2 QOS_ERRORCLASS_SUCCESS" which is the only output I get from > nsis-qos. Does that mean the reservation is done successfully? (I'm a > bit confused by the "ERROR" part... ;)). If I am not mistaken, there is only one object to indicate error or success. Thus, ERRORCLASS_SUCCESS should just mean "success". I guess you do not need to worry. Bernd, is that true? > What I'm doing is the following, > - (All nodes avec nsis daemon with qos enabled runing) > - I measure the bandwith with iperf > (http://sourceforge.net/projects/iperf) between the two hosts (ie +/- > *75MBits*) > - Then I run "nsis-qos 100.0.9.2" on host1, to make my reservation to > host3 > - I make a iperf test to see the difference... and I get +/- *80Kbits*! > > ... If I'm not wrong this is like the iperf's flow was recognized as an > "unclassified flow" > (ie: qos.simplermf.interface[eth0].min_unclassified_bandwidth = 100kbit > in nsis.conf). > > Am I doing something wrong? On startup you have this: (TC) Running "tc qdisc delete dev eth0 root handle 1:" (IpTables) Running "iptables -t mangle -F PREROUTING" (TC) Running "tc qdisc add dev eth0 root handle 1: htb default 2" (TC) Running "tc class add dev eth0 parent 1: classid 1:1 htb rate 100mbit burst 15k" (TC) Running "tc class add dev eth0 parent 1:1 classid 1:2 htb rate 100kbit ceil 100mbit" (TC) Running "tc qdisc add dev eth0 parent 1:2 handle 2: sfq perturb 10" ClsRMF::device = eth1 overall_rate 100mbit, default_rate 100kbit, default_max_rate 100mbit, float max_bw 104857600.000000 (TC) Running "tc qdisc delete dev eth1 root handle 1:" (IpTables) Running "iptables -t mangle -F PREROUTING" (TC) Running "tc qdisc add dev eth1 root handle 1: htb default 2" (TC) Running "tc class add dev eth1 parent 1: classid 1:1 htb rate 100mbit burst 15k" (TC) Running "tc class add dev eth1 parent 1:1 classid 1:2 htb rate 100kbit ceil 100mbit" (TC) Running "tc qdisc add dev eth1 parent 1:2 handle 2: sfq perturb 10" ClsRMF::device = eth2 overall_rate 100mbit, default_rate 100kbit, default_max_rate 100mbit, float max_bw 104857600.000000 (TC) Running "tc qdisc delete dev eth2 root handle 1:" (IpTables) Running "iptables -t mangle -F PREROUTING" (TC) Running "tc qdisc add dev eth2 root handle 1: htb default 2" (TC) Running "tc class add dev eth2 parent 1: classid 1:1 htb rate 100mbit burst 15k" (TC) Running "tc class add dev eth2 parent 1:1 classid 1:2 htb rate 100kbit ceil 100mbit" (TC) Running "tc qdisc add dev eth2 parent 1:2 handle 2: sfq perturb 10" The output above specifies the link as 100Mbit/s and creates a default reservation for "unclassified traffic" with 100kbit average rate and a ceil of 100 Mbit/s. In other words, as long as there is no other "privileged" traffic going on that needs the bandwidth, the "unclassified" traffic is allowed to use line rate (100 Mbit/s in this case). I found this output that is done when the reservation is being made: (TC) Running "tc cla ... ss add dev eth0 parent 1:1 classid 1:6 htb rate 10000bps ceil 10000bps" (TC) Running "tc qdisc add dev eth0 parent 1:6 handle 6: sfq perturb 10" (IpTables) Running "iptables -t mangle -A PREROUTING --src 100.0.0.1/32 --dst 100.0.9.2/32 -j MARK --set-mark 0x0006" (TC) Running "tc filter add dev eth0 protocol ip parent 1:0 prio 1 handle 6 fw classid 1:6" (TC) Running "tc class add dev eth1 parent 1:1 classid 1:6 htb rate 10000bps ceil 10000bps" (TC) Running "tc qdisc add dev eth1 parent 1:6 handle 6: sfq perturb 10" (IpTables) Running "iptables -t mangle -A PREROUTING --src 100.0.0.1/32 --dst 100.0.9.2/32 -j MARK --set-mark 0x0006" (TC) Running "tc filter add dev eth1 protocol ip parent 1:0 prio 1 handle 6 fw classid 1:6" (TC) Running "tc class add dev eth2 parent 1:1 classid 1:6 htb rate 10000bps ceil 10000bps" (TC) Running "tc qdisc add dev eth2 parent 1:6 handle 6: sfq perturb 10" (IpTables) Running "iptables -t mangle -A PREROUTING --src 100.0.0.1/32 --dst 100.0.9.2/32 -j MARK --set-mark 0x0006" (TC) Running "tc filter add dev eth2 protocol ip parent 1:0 prio 1 handle 6 fw classid 1:6" This creates a new rule for "privileged" traffic. The rule matches all packets from 100.0.0.1/32 to 100.0.9.2/32 (see iptables commands). This traffic is guaranteed to get a rate of 10000 bytes/s (i.e. 80kbit/s) but also has a ceil (maximum) of 80kbit/s. Thus, the result you see is expected. Before making the reservation, the iperf session is treated as "unclassified" traffic and as such is allowed to use line rate (in your config) unless other (privileged) needs the bandwidth. Once you made the reservation, the iperf session is now treated as "privileged" traffic, but the configuration you made for this traffic is to guarantee but also cap the bandwidth at 80kbit/s. Hence, the real question is: What was your intended behavior/configuration? > Is there any mean to give more details about the flow (like protocols > and ports) in the current version of the implementation? The code should support it, but I am not sure if the command line interface has support for it in 0.5.0. Bernd? Regards, Christian

Legacy NAT error
by Julien Lange 05 May '08

05 May '08

Hello, I'm facing the "Legacy NAT" error again... I don't understand it's happening from time to time, without any change of configuration. Do you think it could come from the implementation? I'm pretty sure It can't come from a race between zebra and nsis since I wait for zebra to be "finished" before running nsis. I've attached the output of the nsis daemon (debug 2) on the router5. I also give you the captures I made from another time, where the path used router2 and router3. There are two series of captures, one with errors, the other one when everything was ok. I hope you'll be able to help me, Best regards, Julien.

Fundamental questions about QoS NSLP
by Julien Lange 04 May '08

04 May '08

Hello, I'm trying to test the QoS reservation with openNSIS. Using this (virtual) network (http://users.skynet.be/ilove/lab.png) I would like to reserve a certain bandwith from host1 to host3. First of all, I would like to know what's the meaning of "Received response: 2 QOS_ERRORCLASS_SUCCESS" which is the only output I get from nsis-qos. Does that mean the reservation is done successfully? (I'm a bit confused by the "ERROR" part... ;)). What I'm doing is the following, - (All nodes avec nsis daemon with qos enabled runing) - I measure the bandwith with iperf (http://sourceforge.net/projects/iperf) between the two hosts (ie +/- *75MBits*) - Then I run "nsis-qos 100.0.9.2" on host1, to make my reservation to host3 - I make a iperf test to see the difference... and I get +/- *80Kbits*! ... If I'm not wrong this is like the iperf's flow was recognized as an "unclassified flow" (ie: qos.simplermf.interface[eth0].min_unclassified_bandwidth = 100kbit in nsis.conf). Am I doing something wrong? Is there any mean to give more details about the flow (like protocols and ports) in the current version of the implementation? PS: I've attached the output of nsis daemon running on router6, which is on the reservation path. Thank you in advance for your help, Julien.

There are some checks to detect a legacy NAT, i.e. a NAT that is not GIST-aware. They depend on checking IP addresses. See section 7.2.1 of http://www.ietf.org/internet-drafts/draft-ietf-nsis-ntlp-15.txt "If S=1, the receiver MUST check the source address in the IP header against the interface-address in the NLI, and if these addresses do not match this indicates that a legacy NAT has been found." I recommend using our wireshark/ethereal dissector to capture the packets and take a closer look at the packets. The legacy NAT detection is not well tested yet, so you MAY be hitting a bug. If you can identify who is complaining about which packet, I would like to take a look at this packet. You can also take a look at the debug output right before the error message. Copy/Pasted from your mail: (warn) *** Dmode message from : 100.0.2.2:4> *** (info) GIST message: Version = 1 Hop Count = 4 NSLP ID = 3 Message length = 112 (info) Type = RESPONSE (info) S flag = 0 (info) R flag = 0 (info) E flag = 0 (info) GistMriPathCoupled: length = 56 (info) Direction = Upstream (info) Source IP = 100.0.0.1 (info) Dest IP = 100.0.9.2 (info) GistSessionId: length = 20 (info) 0a000000 0a000000 0a000000 0a000000 (info) GistNetworkLayerInfo: length = 28 (info) IntAddr = 100.0.2.2 (info) RouteStateValidityTime = 100000 (info) GistQueryCookie: length = 36 Here you can see what the source IP address (first line), what the S-flag is set to (8th line), and what the IP address in the NLI (GistNetworkLayerInfo) is. Look at these values in the packet that triggers the legacy NAT error message and you might find out what is going on. Just to make sure: You have no NAT in your setup, right? > > DataSize: 268, HeaderLength: 12, Calc: 268(crit) > *** GistException: Invalid ping message. Length invalid *** The code checks whether or not all 3 of these values are equal, i.e. DataSize == HeaderLength == Calc. Obviously this is wrong in this message. *sigh* I just figured out what the problem is. 268 = 256 + 12. HeaderLength is defined as 8 bits, i.e. wraps around at 256, hence the value of 12. If I am reading my code correctly, the diagnostics NSLP will have the same problem. Seems like we never tried so many nodes. Are you familiar with C? If so, you can go into nslp/ping/PingMessage.h and modify struct ping_header_t. I suggest something like: struct ping_header_t { unsigned char version : 8; unsigned char version : 8; unsigned short length; unsigned int seq; } That should help. Christian

GIST Invalid ping message Length invalid
by Julien Lange 30 Apr '08

Hello, Sorry to bother you again but I am definitely facing some troubles trying to get opennsis to work... 1. Trying to nsis-ping through (from host1 to host3) my test network (see http://users.skynet.be/ilove/lab.png) I got a "invalid ping exception" in the node "router1"... I don't understand what does that mean, can someone help me? (I attached the trace from router1). 2. I wonder how nsis "learn" the routing table. In my test network, I use zebra as a routing daemon and then I run nsis (automatically using netkit). But the nsis doesn't work out of the box... I mean I have to kill nsis and run it again to have to result.. Otherwise I get: ------------------------------------ *** GistException: findOutgoingLocalAddress failed: No local address was found for this destination address (100.0.0.1). Please check your configuration * ------------------------------------ As soon as I have killed and restarted nsis, I can ping the "next" node... 3. On the node router3 or router5, depending on how the routing is made, I got sometimes an error saying that I'm using a "legacy NAT"... Where does this come from? 4. I'm sorry, I have tested Christan's patch, yet... A bit overbooked at the moment, but i'll do it! Thank you very much in advance, Julien. ------------------------------------------- Invalid ping message trace ------------------------------------------- *** API-Call RecvMessage() *** (info) nslp_data : d (info) nd_size : 268 (info) nslp_id : 0x0003 (info) sid : (info) 0x00 (info) 0x00 (info) 0x00 (info) 0x00 ( info) 0x00 (info) 0x00 (info) 0x00 (info) 0x00 (info) 0x00 (info) 0x00 (info) 0x 00 (info) 0x00 (info) 0x00 (info) 0x00 (info) 0x00 (info) 0x00 (info) (info) mri->msgRoutingMethod : 0x0000 (info) mri->s : 0 (info) mri->f : 0 (info) mri->t : 0 (info) mri->p : 0 (info) mri->ipVersion : 0x04 (info) mri->reserved : 0x00 (info) mri->d : 1 (info) mri->b : 0 (info) mri->a : 0 (info) mri->srcAddr : 100.0.0.1 (info) mri->destAddr : 100.0.9.2 (info) mri->srcPrefix : 0x20 (info) mri->destPrefix : 0x20 (info) mri->protocol : 0x00 (info) mri->diffserv_field : 0x00 (info) reliable : 0 (info) security : 0 (info) explicitlyRouted : 0 (info) noGistState : 0 (info) ip_ttl : 0 (info) ip_distance : 0 DataSize: 268, HeaderLength: 12, Calc: 268(crit) *** GistException: Invalid ping message.
