Chris LuandClaude Opus 5.5 3cbace2471 s3: expose ReadAcp/WriteAcp in shell and admin UI, log ACL-upload denials (#12396)
* shell: accept ReadAcp and WriteAcp in per-bucket and service account actions

s3.bucket.access, s3.anonymous.set and s3.serviceaccount.create rejected
ReadAcp and WriteAcp, so the ACL actions the S3 gateway enforces could not
be granted through them. Share one canonical action table across the
three commands and list the ACL actions in their help.

* shell: list ReadAcp and WriteAcp in s3.configure and s3.circuitBreaker help

The -actions usage of both commands stopped at Admin, so the ACL actions
the gateway enforces could only be found in the source. s3.circuitBreaker
now prints the actions it actually accepts.

* admin: offer ReadAcp and WriteAcp in the object store user permissions

The create and edit user forms only offered Read, Write, List, Tagging and
Admin among the bucket permissions, so an identity could not be given the
ACL actions from the UI even though uploads with x-amz-acl need WriteAcp.

* s3api: log the WriteAcp denial of an upload that sets an ACL

An upload or copy that carries x-amz-acl or an x-amz-grant-* header also
needs WriteAcp. When that check denies, the client only sees a bare
AccessDenied and nothing reached the log at the default verbosity, so
the header was never suspected. Log the identity and the missing action.

* s3api: quote the key in the ACL upload denial log

An object key can carry a decoded newline, which let a caller add forged
lines to the default log. Quote the bucket and key, and word the message
so it also fits a policy deny, not only a missing grant.

* shell: say ACL uploads need both Write and WriteAcp

The s3.configure example granted WriteAcp alone, which still fails the
upload's Write check.

* shell: parse S3 action lists with one shared helper

s3.bucket.access, s3.anonymous.set and s3.serviceaccount.create each had
their own validation loop, so a test of the table did not cover the
parsing the commands run. They now call canonicalActionList, which skips
empty entries and repeats. s3.anonymous.set validates before contacting
IAM, and s3.bucket.access still rejects a list with no actions.

* admin: keep bucket-scoped actions the user form cannot show

When a user has both global and bucket-scoped actions, the edit form
shows only the global ones, and saving replaced the identity's actions
with what the form rebuilt, deleting the scoped grants. Carry those
actions through the save.

* admin: list hidden bucket grants in the user edit form

Restoring the bucket-scoped grants the form cannot show kept them active
even when an admin narrowed the user's permissions, with no way to see
or drop them. Show them as checked boxes under Other Bucket Permissions;
unchecking one removes it on save.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* shell: reject an s3.anonymous.set -access list with no actions

A blank list such as ",," parsed to nothing and cleared the bucket's
anonymous grants. Use "none" for that, as s3.bucket.access does.

* s3api: skip the ACL upload denial log for anonymous requests

Anonymous uploads with ACL headers can be sent by anyone, so logging
each denial at the default level lets unauthenticated clients flood the
log. Keep the line for named identities.

* admin: count kept bucket grants when checking an edited user for permissions

The empty check ran before the checked Other Bucket Permissions were
merged, so a user left with only those grants could not be saved.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* admin: list bucket grants of Admin users in the user edit form

parseBucketPermissions returned before reading scoped actions when the
user had Admin, so removing Admin and saving dropped grants such as
WriteAcp:bucket.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* admin: keep unpaired bucket grants as separate checkboxes in the user edit form

The form saves every selected permission on every selected bucket, so
grants such as ReadAcp:a with WriteAcp:b came back as all four pairs.
Show the grants through the picker only when they cover that full
product; otherwise list each grant on its own. Opening the form also
resets the bucket scope left over from the previous user.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* admin: keep grants the edit pickers have no option for

A permission x bucket product was shown through the pickers even when a
bucket was not in the bucket list (deleted, prefix or wildcard grants)
or a permission had no picker option (DeleteBucket, PutBucketQuota).
Saving then dropped those grants. Such grants now go to the checkbox
list, global ones included, and are submitted unchanged.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* shell: name the s3.bucket.access anonymous example by what it grants

Read,Write,List leaves out ReadAcp and WriteAcp, so it is not full
access.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* admin: keep unlisted global grants of Admin users in the user edit form

parseBucketPermissions returned for Admin before splitting global grants
into picker options and the rest, and only raw option values were
re-selected. Saving an Admin user dropped s3tables:* and grants with no
picker option such as DeleteBucket. Admin users now use the same split.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* admin: keep the /* suffix of bucket grants in the user edit form

parseBucketPermissions dropped a trailing /* before matching bucket
options, so saving rewrote ReadAcp:bucket/* as ReadAcp:bucket. The bare
form also matches bucket-level requests such as GET ?acl, so the save
widened the grant. A /* bucket is not a picker option, so the grant now
stays in the checkbox list as written.

* shell: test that s3.bucket.access saves ReadAcp and WriteAcp grants

Chris LuandClaude Opus 5.5 b0c6297041 s3api: per-bucket Block Public Access (BlockPublicAcls, IgnorePublicAcls) (#12381)
* s3api: store and serve a bucket's PublicAccessBlock configuration

PutPublicAccessBlock, GetPublicAccessBlock and DeletePublicAccessBlock
answered NotImplemented. Store the configuration in the bucket entry's
extended attributes next to the ownership controls, carry it in the
cached BucketConfig, and answer Get on an unset bucket with
NoSuchPublicAccessBlockConfiguration like S3 does.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* s3api: refuse public ACLs when a bucket blocks them

With BlockPublicAcls set, a PutObject, CopyObject, CreateMultipartUpload,
POST Object, PutObjectAcl or PutBucketAcl whose canned ACL or grants name
the AllUsers or AuthenticatedUsers group is refused with AccessDenied.
Private and account grants keep working, so clients that send
x-amz-acl: private on every upload are unaffected.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* s3api: ignore public ACL grants for anonymous reads under IgnorePublicAcls

A bucket with IgnorePublicAcls no longer lets an AllUsers grant on the
bucket or on an object answer an anonymous read or listing. Bucket
policies and identity permissions are unaffected.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* s3api: reject PublicAccessBlock bodies with unknown elements

A misspelled element such as BlockPublicAcl was ignored, so the request
succeeded and stored the flag as false. Answer MalformedXML instead, and
store the configuration without the request's namespace.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* s3api: fail closed when a bucket's public access block cannot be read

A stored PublicAccessBlock that does not parse now blocks and ignores
public ACLs instead of acting as if none were set. PutBucketAcl and POST
Object return the bucket lookup error rather than skipping the
BlockPublicAcls check when the bucket config cannot be loaded.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* s3api: test BlockPublicAcls on copy, multipart initiate and a PUT-then-GET

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

* s3api: keep stored public access block bytes on unrelated bucket updates

An unreadable stored configuration was replaced with the in-memory
all-true fallback whenever another bucket setting was updated, losing
the original value. Write the key only when the update changes the
public access block.

Jay Hemnanianduser.email 9059cc2a07 s3: allow PutObjectAcl when auth is off (#12155)
* s3: allow PutObjectAcl when auth is off

* s3: ownerless objects claim the admin account when auth is off

An object written through the filer carries no owner metadata, so
objectOwner fell back to an empty account id and ExtractAcl rejected the
canned ACL's canonical grantee. Extend TestPutObjectAclWithoutAuth to
cover the ownerless case.

* s3: GetObjectAcl reports the admin owner for ownerless objects when auth is off

The same empty-owner fallback produced an ACL response with a blank
Owner ID and a blank canonical grantee.

* s3: ignore the client-supplied account id when auth is off

Auth does not strip AmzAccountId on the iam-disabled path, so the
ownerless fallback could persist a forged owner. requestAccountId
substitutes the admin account, matching the idiom already used in the
upload ACL path.

* fix(s3): re-check routed self-copy eligibility on the locked read

routeInPlace was decided on the pre-lock entry, but the PATCH body
re-reads the entry. A concurrent write changing file mode or MIME in
between left the routed PATCH installing new ACL keys while Attributes
kept the stale mode. Evaluate eligibility against the re-read entry and
retry the self-copy under the distributed lock when it no longer
qualifies.

zhao-ycandChris Lu 483dd4b12e s3api: persist ACLs on PutObject uploads (#11592)
* s3api: persist ACLs on PutObject uploads

Signed-off-by: zhaoyuchen <43179751+zhao-yc@users.noreply.github.com>

* s3api: fix PutObject ACL edge cases found in review

- Only enforce BucketOwnerEnforced when explicitly configured; buckets
  without a stored ownership control keep accepting upload ACLs
- Ignore ACL query parameters on SigV2 requests, which do not sign them
- Mirror signed-query ACL values into headers after authentication so
  grant parsing and resolveFileMode agree on presigned uploads
- Validate only caller-supplied grantees against the account registry;
  default grants now work for accounts outside the local registry
- Reject unknown grantee keys and accept comma-separated grantee lists
  without spaces in ParseCustomAclHeader
- Guard against identities without an account

* s3api: harden upload ACL parsing and authorization

Signed-off-by: zhaoyuchen <43179751+zhao-yc@users.noreply.github.com>

* s3api: evaluate upload ACL grantees individually in policies

A comma-joined grant header or a signed query parameter reached policy
conditions as one value, so a deny on a later grantee did not fire. Split
grant headers into per-grantee values for policy evaluation and share the
grantee pair parser with ParseCustomAclHeader.

* s3api: keep raw grant header values visible to policy conditions

Exact-match conditions written against the signed header value stopped
matching once grantees were split for evaluation. Preserve the original
wire values alongside the per-grantee values so deny policies fire on
either granularity.

* s3api: evaluate upload ACL grants as one canonical list in policies

Conditions on s3:x-amz-grant-* now see a single comma-separated canonical
grant list identical for a single line, repeated header lines, or a signed
query parameter. This keeps StringEquals allows and exact-list or
allowlist (StringNotEquals) denies accurate regardless of wire encoding.
