[Bridge] No UDP NFS over bridges in Linux 2.6.16.x?
Hi, I have 2 servers which are connected to a gateway machine. The gateway and one server are running Linux 2.6.16.2, while the third machine is running 2.6.16.5. The two ethernet ports on the gateway which are connected to the servers are combined into a single ethernet bridge device. Ever since 2.6.16, I have noticed that I can no longer cross-mount the two servers' /home directories via

Linux IP fragment overlap bug (fwd)
...e bug manifests itself in the `ip_glue()` function.... When Linux reassembles IP fragments to form the original IP datagram, it runs in a loop, copying the payload from all the queued fragments into a newly allocated buffer (which would then normally be passed to the IP layer proper). >From ip_fragment.c@376: fp = qp->fragments; while(fp != NULL) { if(count+fp->len > skb->len) { error_to_big; } memcpy((ptr + fp->offset), fp->ptr, fp->len); count += fp-&...

(Fwd) DoS for Linux 2.1.89 - 2.2.3: 0 length fragment bug
...ctively disable a target's IP connectivity. However, for the attack to succeed, the attacker will have to deliver several thousand packets to the target, which can take up to several minutes. A quick exploit and the patch are appended to the end of this post. The problem starts in ip_glue() in ip_fragment.c: /* Copy the data portions of all fragments into the new buffer. */ fp = qp->fragments; count = qp->ihlen; while(fp) { if ((fp->len < 0) || ((count + fp->len) > skb->len)) goto out_invalid; memcpy((ptr + fp->offset), fp->ptr, fp->len); if (count == qp-&...

[Bridge] large packet size doesn't work
Hi, I have just configured a Linux box with kernel 2.6.16.7 and configured two ethernet interfaces (with MTU 1500) in bridge mode. CONFIG_BRIDGE_NETFILTER is enabled. The problem is that ping -s 1500 192.168.0.2 doesn't work from 192.168.0.1 if the systems are separated by the bridge. Normal ping with smaller packet size works ok. What is wrong?

Recent use of Fragroute
Hello, Has anyone used Dug Song's Fragroute recently? I installed it using the security/fragroute port on 5.2 REL and 4.9 STABLE systems. There were no dependency problems. I could not get either system to actually send traffic while Fragroute was enabled, even with the simplest of fragroute.conf files, like: ip_frag 24 print I tried manually changing net.inet.ip.forwarding to 1 via

[Bug 48] conntrack breaks udp path mtu discovery
https://bugzilla.netfilter.org/cgi-bin/bugzilla/show_bug.cgi?id=48 ------- Additional Comments From tatonet@tiscali.it 2004-02-25 15:05 ------- I know that this is an old bug report, but it's still opened... If we save the size of each single fragment we have to face another problem: how should we re-fragment the packet if original fragments were partially or totally overlapped?

[Bridge] Any way of knowing a packet's been defragmented
Hello, Due to a recent change in the bridge code, we now need a way of knowing if a packet has been defragmented. The bridge code now checks on the packet size and drops packets that are too big for the output port. Defragmented packets will get refragmented later, so they shouldn't be dropped. I've been reading the defragmentation code and can't find an easy way of knowing if a
