[pve-devel] [PATCH v1 access-control++ 0/5] SuperUser privilege

[pve-devel] [PATCH v1 access-control++ 0/5] SuperUser privilege

[Oguz Bektas]

"SuperUser" (henceforth referred as SU) privilege allows to give
root-only permissions to API users, enabling them to perform privileged
actions on behalf of root@pam.

this privilege is enabled by default for "root@pam", and also mapped
inside "SuperAdministrator" (referred as SA)

changes from RFC (thanks for the review fabian g.!):
* manager: allow SAs to see/edit certain things on GUI
* qemu-server: also check the required non-root
VM privileges along with the SU priv
* pve-container: adapted error messages, changed variable name to
"is_superuser" for better clarity (in comparison to prev. "is_root"
which is a bit confusing)
* access-control: TFA permissions adaptation for SAs

[pve-devel] [PATCH v1 access-control 1/5] add default "SuperAdministrator" role with the new "SuperUser" privilege

[Oguz Bektas]

we map all valid privileges to the "Administrator" role except "SuperUser".

"SuperAdministrator"/SA gets all valid privileges (including the new
"SuperUser"/SU priv), and 'root@pam' is assigned as an SA by default.

can be shorted (root@pam is by definition a SuperUser), but IMHO, the 
whole comment can be dropped - the variables have meaningful names 
anyway?

some rationale why this was changed, but the very similar code in 
PVE:API2::AccessControl->change_password is not adapted is also missing. 

also, a similar mechanism exists in the other direction as well: 
root@pam can create tickets for other users - should SuperUser also be 
allowed to do that? if not, the reason for that exception should be 
added to the relevant part as comment (or if it should, then the 
relevant changes should be part of the series ;))

one more point - check_api2_permissions has the general 'no permission 
specified in schema => only root@pam allowed' rule. obviously with the 
semantics of 'superuser does not entail all privileges' that can't be 
switched to superuser - but it means all the existing API calls without 
specific permissions need to be checked and either adapted (e.g., with 
an appropriate ACL with regular privilege + SuperUser), or marked as 
root only with a reason. one way to do this would be to analyze the API 
dump, or even forbid endpoints without a permission in the schema (e.g. 
in the api verification code we run at build time), and switch the 
remaining root-only endpoints to just have an explicit permission in the 
schema that encodes that. obviously in any case the check in 
check_api2_permissions needs to remain to catch anything that slipped 
through.

[pve-devel] [PATCH v1 container 3/5] fix #2582: api: add checks for 'SuperUser' privilege for root-only options

[Oguz Bektas]

this way we can allow non-root users to act as a SU on specific
root-only API paths by giving them the built-in SA role or a custom role
with the SU privilege included.

schema still has root-only in the description, both here and in the

so.. 'SuperUser' on its own should only skip those parts where root@pam 
was previously a requirement on top of other checks, but instead 
'SuperUser' can now modify the config however even with no other privs?

here there is the non-volume part that is still root-only, with no 
comment about why that one is not switched to 'SuperUser'?

also, features for privileged containers is still root-only (should 
probably require VM.Allocate + SuperUser, when looking at the

[pve-devel] [PATCH v1 manager 4/5] change 'root@pam' checks with 'SuperUser' capability check

[Oguz Bektas]

'root@pam' has the privilege by default (since it's an SA), so we can
drop the string comparisons all around and check that privilege instead
when deciding to enable/disable buttons or views

but if you change this here, you also need to change the backend - as 
this is currently root-only (the API path called by the Ceph install 
wizard requires Sys.Console which is not a given just because you have 
SuperUser, and the ceph_install handling itself requires root@pam - the 
user is then presented with a login shell). so either this remains 
root-only for now (like the upgrade thing - both have the same problem 
after all!), but then please add a comment why or mention that in the 
commit message - or you find a good safe solution, then please argue why 
it is safe ;)

the plugins actually require 'Sys.Modify', and the account endpoints are 
unqualified (root-only) or open to everyone (those returning 
schema/static stuff for front-end re-use) at the moment but that can 
probably be re-evaluated. in any case, switching this just in the 
front-end cannot work..

no rationale given for the different way of accessing - I'll leave it to 
more JS affine reviewers to decide whether this is sensible or not, but 
please provide the reason WHY this doesn't use `caps.access['SuperUser']`

also, it's wrong - a SuperUser still requires User.Modify to modify 
users, so this either needs to stay as it is or simply drop the root@pam 
shortcut.

we discussed this in depth and said we'll keep the upgrade console root 
only for now.. also, the backend isn't change to allow this for 
SuperUser so it's moot anyway?

just to give the reason:

eslint complains if we use foo['bar'] when we could use foo.bar

we prefer 'dot-notation' (so foo.bar.baz) for objects, but in
all other cases of the caps object that does not work because
the keys themselves contain a '.'

one just add a comment to tell eslint to ignore that one in that case
though, else this may always look a bit weird to people reading over the
code by accident.

[pve-devel] [PATCH v1 qemu-server 5/5] add SuperUser privilege checks for root-only options

[Oguz Bektas]

analogous to the changes in container.

we now allow users with SU privilege to edit real device configurations,
provided that they also have the necessary VM privileges.

note that root@pam is still able to do everything as usual

Re: [pve-devel] [PATCH v1 qemu-server 5/5] add SuperUser privilege checks for root-only options

[Fabian Grünbichler]

this needs a rebase anyhow, I reviewed it on HEAD~3 where it still 
applies ;)

there's one check for 'root@pam' that looks okay
same for the one in the move disk API endpoint

it might be worth it to mention that you checked those and not switched 
them to superuser since they are only a shortcut for skipping the 
permission check for root, and not limiting access to some root-only 
action (or maybe even add a comment so that future people looking at it 
don't have to remember that).

nope - this still needs to check VM.Config.HWType in the SuperUser 
case..

e.g., should look like this:

my $check_vm_create_serial_perm = sub {
    my ($rpcenv, $authuser, $vmid, $pool, $param) = @_;

    return 1 if $authuser eq 'root@pam';

    my $is_superuser = $rpcenv->check($authuser, "/vms/$vmid", ['SuperUser'], 1);

    foreach my $opt (keys %{$param}) {
	next if $opt !~ m/^serial\d+$/;

	$rpcenv->check_vm_perm($authuser, $vmid, $pool, ['VM.Config.HWType']);
	die "only superusers can set '$opt' config for real devices\n"
	    if !($param->{$opt} eq 'socket' || $is_superuser);
    }

    return 1;
};

completely wrong, like in pve-container! this effectively skips most 
checks for SuperUser, instead of only skipping the root-only parts..

only the else part of $check_vm_modify_config_perm should check for 
superuser and die otherwise..

this isn't 100% correct either - most of these are migration-internal 
parameters (which are only ever supposed to be set when called via SSH 
via `qm`, which runs as root@pam anyway)

skiplock can switch to being superuser-limited, the rest should stay 
root@pam..

and this one is again only set when stopping the target VM during 
migration (via ssh, via qm, so always root).

this is also migration only (for resuming while the config is still on 
the source node)

Re: [pve-devel] [PATCH v1 access-control++ 0/5] SuperUser privilege

[Fabian Grünbichler]

see individual patches for in-depth review of changes, some broader 
remarks:
- I am missing info about parts you looked at but left as-is (and 
  rationale for why those parts stay root only)
- especially relevant would be a list of currently 
  unqualified/root-only-by-default API endpoints and actions taken or 
  not taken + reasons

e.g. some parts that are missing that I found with random grepping (in 
addition to stuff I mentioned in my other replies), where I have no idea 
whether you even look at them and decided they are okay as-is, or missed 
them:

- PVE::API2::Backup (tmpdir, dumpdir, script parameters)
- PVE::API2::VZDump (maxfiles prune-backups tmpdir dumpdir script bwlimit ionice)
- PVE::API2::ClusterConfig (we talked about that off-list, but some 
  mention in the actual patch series would still be good)
- PVE::Storage::check_volume_access , which is used in quite a few 
  places..
