Subject: liblwipv6-2: seqv when using mstack ... ip link depending on path

Date: Mon, 28 Jul 2008 18:13:30 +0200

Package: liblwipv6-2
Version: 1.2a-1
Severity: normal

depending on the path where I start umview I get strange results, otr a seqV:
achim@debian64:~/.wine/drive_c/Program Files$ umview -p umnet bash
This kernel supports: ppoll
UMView will use: ppoll

umnet init
achim@debian64:~/.wine/drive_c/Program Files$ !moun
mount -t umnetlwipv6 -o tn0=tap0 none /dev/net/yourip
achim@debian64:~/.wine/drive_c/Program Files$ !ms
mstack /dev/net/yourip ip link
1: lo0: <LOOPBACK,UP> mtu 0
    link/loopback
2: tn0: <> mtu 65535
    link/void ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:74:6e:00:40:00:02:ff:ff:ff:ff:ff: brd ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:

achim@debian64:~/.wine/drive_c/Program Files$

One up:
chim@debian64:~/.wine/drive_c$ !umv
umview -p umnet bash
This kernel supports: ppoll
UMView will use: ppoll

umnet init
!moachim@debian64:~/.wine/drive_c$ !moun
mount -t umnetlwipv6 -o tn0=tap0 none /dev/net/yourip
achim@debian64:~/.wine/drive_c$ !ms
mstack /dev/net/yourip ip link
1: lo0: <LOOPBACK,UP> mtu 0
    link/loopback
2: tn0: <> mtu 32
   link/[244] 04:00:00:00:00:00:00:20:00:00:74:6e:00:40:00:02 brd ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff:ff
achim@debian64:~/.wine/drive_c$ exit

(Actually I got sometimes as well a SEQV, and somethmes no strange link line for tn0)

one uo:
achim@debian64:~/.wine$ umview -p umnet bash
This kernel supports: ppoll
UMView will use: ppoll

umnet init
!achim@debian64:~/.wine$ !moun
mount -t umnetlwipv6 -o tn0=tap0 none /dev/net/yourip
achim@debian64:~/.wine$ !ms
mstack /dev/net/yourip ip link
1: lo0: <LOOPBACK,UP> mtu 0
    link/loopback
2: tn0: <> mtu 0
    link/generic
achim@debian64:~/.wine$

This is always fine

Why are you trying to create a TUN interface (tn0) connected to a TAP
interface (tap0)?

Please try with tp0=tap0. (In the meanwhile I'm investigating.)

Do you still have this problem? I am going to upload a new release of
lwipv6. Unless you're able to confirm that the issue is still there in
lwipv6-1.5a-1 (which should in Debian by tomorrow) I'll close this bug.
lwipv6 has undergone very deep changes in these 3 years and many bugs
were solved.

Thanks,

Ludovico

I'm closing the bug, as I got no reply in 6 months and there has been
no feedback since 2008.
