| |
Hello,
I probably found a buf somewhere in the (v)fs layer. I do mount smb filesystems over the network. Mounting works fine, say I do a
mount -t smbfs -o username="..." //1.2.3.4/test /mnt/windows ls /mnt/windows
(that gives, e.g. some files and directories...)
ls /mnt/windows/somedirectory dies with a segfault and I find the following stuff on the syslog:

As you see, the bug is reproducible (at least three times). Of course I rebooted my computer always after these things happened.
