[pdm-devel] [PATCH datacenter-manager 0/3] fix #6901: allow non root users to access the EVPN dashboard

[pdm-devel] [PATCH datacenter-manager 0/3] fix #6901: allow non root users to access the EVPN dashboard

[Shan Shaji]

When a non-root user tried to access the EVPN section, the API was
returning a "403: permission check failed" error. To fix this, explicit
permission checks have been added for the `/zones`, `/vnets`, and
`/controllers` endpoints.

Now, every authenticated user can access these endpoints however, the user
must have at least the Resource.Audit permission under `/resource`.
Remotes are also filtered based on the user’s access. Lists will only be
fetched from remotes for which the user has at least the
`Resource.Audit` permission on `/remote/{remote_name}`.

Shan Shaji (3):
  fix #6901: api: add explicit permission check for controllers list
  fix #6901: api: add explicit permission check for vnets list
  fix #6901: api: add explicit permission check for zones list

[pdm-devel] [PATCH datacenter-manager 1/3] fix #6901: api: add explicit permission check for controllers list

[Shan Shaji]

When a non-root user tried to access the EVPN section, the API was
throwing "403: permission check failed" error. To fix this, add
explicit permission check for the `/controller` endpoint.

Now every authenticated user can access the endpoint however, the user
needs to have at least `Resource.Audit` permission under `/resource`.
Only the controllers from remotes which the user has `Resource.Audit`
privilege on `/remote/{remote_name}` will be included in the returned
list.

[pdm-devel] [PATCH datacenter-manager 2/3] fix #6901: api: add explicit permission check for vnets list

[Shan Shaji]

When a non-root user tried to access the EVPN section, the API was
throwing "403: permission check failed" error. To fix this, add
explicit permission check for the `/vnets` endpoint.

Now every authenticated user can access the endpoint however, the user
needs to have at least `Resource.Audit` permission under `/resource`.
Only the vnets from remotes which the user has `Resource.Audit`
privilege on `/remote/{remote_name}` will be included in the returned
list.

we use UNAUTHORIZED instead of FORBIDDEN in other places, so imo would
be better to do that here too - same for the other 2 patches as well.

this was already discussed for a previous patch series. UNAUTHORIZED
there is arguably false, as we usually return a 403 FORBIDDEN when a
user does not have sufficient permissions (e.g. that's what you get if
you define permissions through the api macro and a user doesn't have
them). not a 401 UNAUTHORIZED, which we use to indicate that the user
has not been authenticated (i.e. no or invalid ticket).

iirc Permission::Anybody above means that anybody that has been
authenticated can access this endpoint (as opposed to Permission::World,
which means even unauthenticated users can access it). hence, we know
the user is authenticated here. so this is fine, but returning 401
UNAUTHORIZED in those other endpoints is wrong imo.

note that the ui relies on that in many cases: a 401 will trigger the
login prompt to be shown again, a 403 will simply show an error.

[pdm-devel] [PATCH datacenter-manager 3/3] fix #6901: api: add explicit permission check for zones list

[Shan Shaji]

When a non-root user tried to access the EVPN section, the API was
throwing "403: permission check failed" error. To fix this, add
explicit permission check for the `/zones` endpoint.

Now every authenticated user can access the endpoint however, the user
needs to have at least `Resource.Audit` permission under `/resource`.
Only the zones from remotes which the user has `Resource.Audit`
privilege on `/remote/{remote_name}` will be included in the returned
list.

Re: [pdm-devel] [PATCH datacenter-manager 0/3] fix #6901: allow non root users to access the EVPN dashboard

[Stefan Hanreich]

We might want to to reimplement more granular permissions as well, while
we're at it. Guests have /remotes/<remote>/guest/<vmid> for instance to
allow setting permissions on a per-guest level.

Imo, nothing speaks against implementing permissions the same way as SDN
currently does, which would then be on PDM side:

/remote/<remote>/sdn/zones/<zone>
/remote/<remote>/sdn/zones/<zone>/<vnet>
/remote/<remote>/sdn/controllers/<controller>

Thanks @Stefan for the review. Got it, Thank you for explaning it. 
I think it would be better to implement it in another patch series.
WDYT?
