[Dazuko-devel] dazukoSetAccessMask Attributes: ON_CREATE, ON_MKDIR (Feature request)

[karel van ijperen]

Good evening Dazuko Developers,

After some research I found that the Dazuko module could be excellent 
for one of my future (non security related) project's...
if it included two more functionalities: Monitor whether the open() 
syscall created a new file or just opened an existing one, and
when a directory has been made. I guess that the later one is the 
easiest to implement, however I have not done any kernel level
development so I do not know about the hook's, or other things that are 
involved in adding this feature but I think that they are not
supported for file creation in linux. Therefore it might be a daunting 
task to implement it. If this is the case please inform me on
this so I can figure it out myself and maybe even send a patch and 
inform you guy's. The last thing I want is keeping the Dazuko
comunity busy with new features and kernel hacking, as the time is more 
needed for making it ready for production systems (sort
of quote from the dutch Linux magazine) and security related 
features/issues as this is what Dazuko is created for.

The reason I need this is because my project will be a daemon that 
updates the [s]locate databases real time (or buffer till [s]locate is
called and than write to the databases) this way the [s]locate database 
includes just installed files in it's search and the system does
not suffer a performance hit when my cron deamon updates my databases. 
Only when something goes terebly wrong or when
directories included in the [s]locate are managed outside the presence 
of my deamon (for instance in a dual boot system) updatedb
needs to be runned. For this daemon to work it need's to know when 
unlink() is called or when open() creates a new hardlink, when
directories are created and removed and possibly when [s]locate is run 
(for emergency buffer flushing). That is what i want Dazuko
to do for me. There may be little to no impact on system performance, if 
this is not possible the project will be dropped.

It is the first time I signed up on any mailing list, I did not want to 
force you devers to go though any preceding chatter either,
therefore I am very sorry if it bothered anyone that I did not properly 
introduce myself and cut to the chase. Please contact me trough
e-mail at address@hidden or IRC on irc.freenode.net (nickname SpaT) 
where I am often present.

Kind regards,

Spat
