Ronnie,

Thank you for the idea.

Jeremy and Ralph, attached is a first stab at this. There is a warning.
In one place in the module there is a smb_fname = fsp_name that is set
to be const. For this reason, I have made the function to mark things as
offline have the smb_fname parameter const. Unfortunately,

../source3/modules/vfs_virusfilter.c: In function ‘infected_mark_offline’:
../source3/include/vfs_macros.h:398:50: warning: passing argument 2 of
‘smb_vfs_call_get_dos_attributes’ discards ‘const’ qualifier from
pointer target type [-Wdiscarded-qualifiers]
  smb_vfs_call_get_dos_attributes((handle)->next, (smb_fname), (attributes))


As the two of you know Samba's internals much better than I, would you
mind advising me on the correct way to go about fixing the warning and
doing a preliminary review. Also, I do not know if this would be best to
be default behavior. I have it currently defaulted to true.

Alternatively, this could work more like vfs_offline and simply modify
the return for the get dos attributes and fget dos attributes to be
offline if the file is infected in the cache. i.e. no permanent
attribute on disk, but would only work so long as files are in the scan
results cache.

Thank you.
