Hello Samba Developers,
Recently I've caused an endless loop in Samba, which caused the log file
to fill up all usable disk space.
This is what I've done ( or better, what I think I've done, because the
bug is not reproduceable ) :
- Mounted my home directory via Windows Explorer under Windoze NT.
- Logged into account under same name on same machine ( bash )
- created a soft link to another users directory in my home directory :
ln -s ../murr
- refreshed the display in Windoze Explorer. The previously created link
now appears as a directory.
- double clicked on the link, went 2 directory levels deeper to directory
~murr/intranet/services
- Opened a few files there
- Removed the soft link from shell level. At the time Windoze Explorer was
still in the same directory. I agree, that it is not a smart idea to
access files through a link which has been manually removed. I can't
remember if Explorer displayed any error, but I think it didn't.
About 20 minutes later the disk was full, with entries all looking like
the following ones.
All attempts to reproduce the bug failed, so maybe I was doing something
else, I simply can not remember.
The machine here is Linux kernel 2.2.14.
Samba version is 2.0.6, as supplied in Suse Linux 6.4.
More details in attached testparam output.
Configuration is pretty much plain vanilla, except that the machine is
configured as a master browser.
Best regards
Andreas
