Hi I want to change the permissions of all the keys within a domain with one shot. Currently I am having to individually do # xenstore-chmod /local/domain/24/device rw # xenstore-chmod /local/domain/24/device/vfb rw # xenstore-chmod /local/domain/24/device/vfb/0 rw # xenstore-chmod /local/domain/24/device/vfb/0/state rw # xenstore-chmod /local/domain/24/device/vfb/0/backend-id rw # xenstore-chmod /local/domain/24/device/vfb/0/backend rw And so on, where 24 is the domain id of the domain whose xenstore I want to share and rw are the permissions. This is true with PVs and HVMs for them to allow other domains to be able to access their xenstore. Is there any way that I can do this in one shot, either using xenstore-chmod or using the configuration file while creating the guest, either PV or HVM??

I think it would be sensible for xenstore-chmod (et al) to have this
as an option, -R perhaps.
If you were to write your code for recursion so it was useable and
used by xenstore-chmod (and perhaps the other utilities) then please
do send us the patch.
Ian.

Ian, I''ll try and do so. I''m yet to go through the xs-chmod
code which I''m expecting to be easy. Plus I''m not aware of the
reviewing/patching process so I may come back to you on that.
Bhaskar.

Excellent.

Just post it here on xen-devel.
You should include a Signed-Off-By line like this
Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>
except with your name and email address. This indicates that you are
certifying the code as suitable (copyright-wise and so on) for
inclusion in Xen. You can find the precise meaning in the Linux
upstream kernel tree (Documentation/SubmittingPatches).
