Subject: [PATCH 0/3] keys: play nicely with user namespaces
Date: Thu, 11 Dec 2008 17:23:23 -0600	[thread overview]
Message-ID: <20081211232323.GA8343@us.ibm.com> (raw)

Hi David,

so here is a first attempt at getting keys and uid namespaces
to play nice.  The semantics need some discussion.  As I recall
Eric and yourself appeared to agree that some keyrings should
be inherited into child user namespaces.  I segragate them
cleanly bc that appears to be the simplest thing to do especially
given the use of i.e. lookup_by_name("uid.500").  IMO it shouldn't
be a big problem - userspace can always list keys it wants into a
file, start a new user namespace, then re-read them out of the
tempfile...

Comments appreciated.

thanks,
-serge
