Subject: [PATCH] event: filter global events by domain:getattr ACL

CVE-2014-0028

Ever since ACL filtering was added in commit 7639736 (v1.1.1), a

user could still use event registration to obtain access to a

domain that they could not normally access via virDomainLookup*

or virConnectListAllDomains and friends.  We already have the

framework in the RPC generator for creating the filter, and

previous cleanup patches got us to the point that we can now

wire the filter through the entire object event stack.

Furthermore, whether or not domain:getattr is honored, use of

global events is a form of obtaining a list of networks, which

is covered by connect:search_domains added in a93cd08 (v1.1.0).

Ideally, we'd have a way to enforce connect:search_domains when

doing global registrations while omitting that check on a

per-domain registration.  But this patch just unconditionally

requires connect:search_domains, even when no list could be

obtained, based on the following observations:

1. Administrators are unlikely to grant domain:getattr for one

or all domains while still denying connect:search_domains - a

user that is able to manage domains will want to be able to

manage them efficiently, but efficient management includes being

able to list the domains they can access.  The idea of denying

connect:search_domains while still granting access to individual

domains is therefore not adding any real security, but just

serves as a layer of obscurity to annoy the end user.

2. In the current implementation, domain events are filtered

on the client; the server has no idea if a domain filter was

requested, and must therefore assume that all domain event

requests are global.  Even if we fix the RPC protocol to

allow for server-side filtering for newer client/server combos,

making the connect:serach_domains ACL check conditional on

whether the domain argument was NULL won't benefit older clients.

Therefore, we choose to document that connect:search_domains

is a pre-requisite to any domain event management.

Network events need the same treatment, with the obvious

change of using connect:search_networks and network:getattr.
