Hi, Richard
 
   I have another question, samba VFS module doesn't allow to use \
strcpy/strcat/sprintf, and if I use the safe version such as fstrcpy, but I got \
__unsafe_string_function_usage_here__, how can I get safe string function for samba \
module using.

Hi, Richard

   Thanks for your advice, and I will update it to a new version, with your excellent \
paper "Writing a Samba VFS", I wrote a VFS module, but when I debug the samba code, I \
found a strange thing, the close operation always is delayed about 15 seconds when I \
do a file copy, can the close operation be called just after writing all data \
immediately?

Hi,

Even 3.6.9 is really old, and you should try to use something more recent. The SerNet \
folks were making source and binary RPMs available for more recent version of 3.6, so \
you should probably go with those if you want to stick with a 3.6.x version, and \
installing their RPMs is not so hard.

I notice that the latest there is from March in 2014 which is quite recent:

http://ftp.sernet.de/pub/samba/3.6/centos/6/

However, for Samba 4 you will need to register with them, as it says
here: http://ftp.sernet.de/pub/samba/4.0/README.txt

Building an RPM from their source RPM is also not that hard, especially as it seems \
you want to make some mods.
