AccountInfo is quite frequently called by the Console UI
login attempts, when many users are logging in it is important
that we provide them with better responsiveness.
- ListBuckets information is cached every second
- Bucket usage info is cached for up to 10 seconds
- Prefix usage (optional) info is cached for up to 10 secs
Failure to update after cache expiration, would still
allow login which would end up providing information
previously cached.
This allows for seamless responsiveness for the Console UI
logins, and overall responsiveness on a heavily loaded
system.
A new middleware function is added for admin handlers, including options
for modifying certain behaviors. This admin middleware:
- sets the handler context via reflection in the request and sends AuditLog
- checks for object API availability (skipping it if a flag is passed)
- enables gzip compression (skipping it if a flag is passed)
- enables header tracing (adding body tracing if a flag is passed)
While the new function is a middleware, due to the flags used for
conditional behavior modification, which is used in each route registration
call.
To try to ensure that no regressions are introduced, the following
changes were done mechanically mostly with `sed` and regexp:
- Remove defer logger.AuditLog in admin handlers
- Replace newContext() calls with r.Context()
- Update admin routes registration calls
Bonus: remove unused NetSpeedtestHandler
Since the new adminMiddleware function checks for object layer presence
by default, we need to pass the `noObjLayerFlag` explicitly to admin
handlers that should work even when it is not available. The following
admin handlers do not require it:
- ServerInfoHandler
- StartProfilingHandler
- DownloadProfilingHandler
- ProfileHandler
- SiteReplicationDevNull
- SiteReplicationNetPerf
- TraceHandler
For these handlers adminMiddleware does not check for the object layer
presence (disabled by passing the `noObjLayerFlag`), and for all other
handlers, the pre-check ensures that the handler is not called when the
object layer is not available - the client would get a
ErrServerNotInitialized and can retry later.
This `noObjLayerFlag` is added based on existing behavior for these
handlers only.
This would better to record the correct API name so that
any verification around audit logs to figure out if required
APIs are called required no of times, would be correct.
Here in this case of policy attached, API `AttachDetachPolicyBuiltin`
would be called with `requestPath` as `/minio/admin/v3/idp/builtin/policy/attach`
and in case of detach policy the value would be `/minio/admin/v3/idp/builtin/policy/detach`

For policy attach/detach API to work correctly the server should hold a
lock before reading existing policy mapping and until after writing the
updated policy mapping. This is fixed in this change.
A site replication bug, where LDAP policy attach/detach were not
correctly propagated is also fixed in this change.
Bonus: Additionally, the server responds with the actual (or net)
changes performed in the attach/detach API call. For e.g. if a user
already has policy A applied, and a call to attach policies A and B is
performed, the server will respond that B was attached successfully.
This PR changes the handling of bucket deletes for site
replicated setups to hold on to deleted bucket state until
it syncs to all the clusters participating in site replication.
currently, we allowed buckets to be listed from the
API call if and when the user has ListObject()
permission at the global level, this is okay to be
extended to GetBucketLocation() as well since
GetBucketLocation() is a "read" call and allowing "reads"
on a bucket has an implicit assumption that ListBuckets()
should be allowed.
This makes discoverability of access for read-only users
becomes easier or users with specific restrictions on their
policies.
this PR introduces a few changes such as
- sessionPolicyName is not reused in an extracted manner
to apply policies for incoming authenticated calls,
instead uses a different key to designate this
information for the callers.
- this differentiation is needed to ensure that service
account updates do not accidentally store JSON representation
instead of base64 equivalent on the disk.
- relax requirements for Deleting a service account, allow
deleting a service account that might be unreadable, i.e
a situation where the user might have removed session policy
which now carries a JSON representation, making it unparsable.
- introduce some constants to reuse instead of strings.
