| I just mailed to maintainer, but I'm afraid problem is in samba vfs,

|
| But here is vscan output with 3.0.11, when I'm writing memTest.exe to dir:
|
| Mar 23 08:57:59 backup smbd_vscan-clamav[6247]: INFO: Scanning file :
| '/home/samba/definity/DIST/memTest.exe'
| Mar 23 08:57:59 backup smbd_vscan-clamav[6247]: INFO: file
| /home/samba/definity/DIST/memTest.exe is clean
|
|
| And here is output with 3.0.12:
| Mar 23 09:00:10 chr smbd_vscan-clamav[3668]: INFO: Scanning file :
| '/home/samba/common/'
|
| As you see, now vscan scans _whole_  share!
| Looks like there was changes in vfs code in 3.0.12 :-)

I could check the svn logs, but either way the vscan module will
need to be updated for Samba 3.0.12 so this is a vscan issue IMO.
If you can send me the source for the VFS module and details on
how to reproduce the issue, I'll take a look.




cheers, jerry
