> h2. Background
> HDDS-9117 (PR [#5144|https://github.com/apache/ozone/pull/5144]) changed
> \{{getBucketInfo}} so linked buckets return selected operational properties
> from their resolved source bucket.
> HDDS-15624 (PR [#10745|https://github.com/apache/ozone/pull/10745])
> refactored that behavior into shared logic and applied it to \{{listBuckets}}.
> The source-access and encryption-information gaps already existed in
> \{{getBucketInfo}}. HDDS-15624 preserved them there and extended them to
> \{{listBuckets}}.
> Two consistency gaps remain.
> h2. Problem
> *Source access handling*
> Source properties should only be copied after confirming that the source
> bucket can be accessed by the current caller. If the source cannot be
> resolved or accessed, the API should return the stored information for the
> link bucket without copying properties from the source.
> This behavior should be consistent between {{getBucketInfo}} and
> {{{}listBuckets{}}}. A single link whose source properties cannot be
> retrieved should not cause the entire bucket listing to fail.
> *Encryption information*
> {{OmBucketInfo.withOperationalPropertiesFrom}} copies replication, layout,
> quota, usage, metadata, tags, and other source properties, but it does not
> copy {{{}BucketEncryptionKeyInfo{}}}.
> A link bucket cannot define its own encryption key. Therefore, a link to an
> encrypted source currently retains a null encryption value. RPC clients
> consequently return null from {{{}OzoneBucket.getEncryptionKeyName(){}}}, and
> OFS may report the linked bucket as unencrypted even though its source is
> encrypted.
> h2. Expected behavior
> * Check access to the resolved source bucket before copying its operational
> properties.
> * If the source cannot be resolved or accessed, return the stored
> information for the link bucket. For {{{}listBuckets{}}}, continue processing
> the remaining entries.
> * When the source properties can be returned, include the source bucket
> encryption information along with its other operational properties.
> * Preserve the link identity fields, including its volume, bucket name,
> owner, source path, ACLs, timestamps, and object/update IDs.
> h2. References
> * HDDS-5530
