Chris Lu	a0b1272cc3	filer: authorize the chunk proxy and the root listing like the rest of the filer port (#11152) ... * filer: require a read token for the root listing maybeCheckJwtAuthorization waved through every GET/HEAD on "/", so a filer with jwt.filer_signing.read.key set still served its root directory listing -- entry names, sizes and chunks[].file_id -- to a caller holding no token at all, and served the same listing to a token restricted by allowed_prefixes. The exemption was added for health checks before the filer had /healthz and /readyz. Both are registered on the default and read-only muxes ahead of the "/" handler and answer without a token, so drop it. Point the mTLS harness at /healthz, which is what it was probing for. * filer: keep the jwt query parameter out of a proxied chunk request The proxy stripped "jwt" from the forwarded query on reads only, on the grounds that a writer's own credential travels there. It does not: an uploader carries its AssignVolume token in the Authorization header, and the query parameter on this path holds a filer credential. Strip it for every method. A volume server has no business seeing a filer token, and because security.GetJwt reads the query before the header, relaying one would hide the writer's own token behind it. * filer: dispatch the chunk proxy after the JWT gate The ?proxyChunkId= branch returned before maybeCheckJwtAuthorization ran, so GET, PUT, POST and DELETE against any needle in the cluster were reachable on the filer's HTTP port with no filer credential, on a filer where every other request answered 401. An anonymous caller read a stored object, replaced its bytes, or deleted the needle, which the master's next vacuum makes permanent. #10434 stopped the filer from minting a volume write token for that caller, which closes the write half only where the volume server has a jwt.signing.key of its own -- not the shipped default, and not what scaffold/security.toml recommends for a filer deployment. The read half stayed open in every configuration, because the filer mints the read token itself. Move the dispatch below the gate. A file id carries no path, so a token restricted by allowed_prefixes cannot be scoped against one and is refused here; every consumer of this endpoint holds an unrestricted token. * filer: mint the volume credential for a proxied write too The proxy minted a volume token on reads and forwarded whatever the caller sent on writes. #10434 made it that way because the branch ran ahead of the JWT gate, so a token minted here would have been signed for an unauthenticated caller; the branch now runs behind the gate, and the credential the caller presents there is a filer one, which a volume server cannot validate and has no business seeing. Mint at the access level the request needs, and drop the caller's Authorization when there is no key to mint from. A proxied uploader then needs only the filer credential, instead of holding one for each hop with a single header to put them in. * mount, mq, filer.sync: send the filer credential for a proxied chunk Every in-tree consumer of ?proxyChunkId= reached the filer anonymously: mount and the broker put the AssignVolume token in the Authorization header, which is a volume credential, and filer.sync sent nothing at all. That was enough only while the branch ran ahead of the filer's JWT gate. Build the URL through one helper, and pick the credential from the URL it returns: a chunk proxied through a filer is a request to the filer, which authorizes it and attaches the volume credential itself, so the token there is a filer one at the access level the request needs. * filer: honor -exposeDirectoryData The flag was declared on all three commands that start a filer and read by none of them: FilerOption.ExposeDirectoryData was only ever assigned from filer.expose_directory_metadata in security.toml, so -exposeDirectoryData=false silently left the listing exposed. Only the TOML key had any effect. Plumb the flag through and let either switch turn the listing off. * filer: count a proxied chunk request once Moving the dispatch below the gate put it after the deferred request observation, so every proxied chunk now landed in FilerRequestHistogram twice, once under its HTTP method and once under chunkProxy. Name the deferred one after the proxy instead, the way the unsupported-method branch already does, which also gives the endpoint the status codes FilerRequestCounter records.	2026-09-04 16:39:36 -07:00
Chris Lu	3431bdcb74	s3: fix UploadPartCopy with volume-data encryption (#10971) ... * operation: give an encrypted chunk the plaintext ETag With -encryptVolumeData the volume server stores ciphertext, so it cannot echo a Content-MD5 back and the chunk lands with an empty ETag. Every ETag derived from those chunks then comes out empty for a single chunk, or d41d8cd98f00b204e9800998ecf8427e-N for several. The caller already hashes the plaintext to send as Content-MD5, so keep that digest as the chunk ETag instead of dropping it, and compute it for a WantMd5 caller under cipher too. * s3: re-encrypt a part copy from a volume-encrypted source UploadPartCopy raw-copies source chunks when neither side uses SSE, which also caught -encryptVolumeData sources. Those chunks are ciphertext a whole-chunk cipher key decrypts, so copying a byte range out of one and keeping the key leaves a destination that fails authentication on GET, and the copied chunks carry no ETag for the part result to report. Route them through the re-encrypting path already used for SSE: it reads the source as plaintext, hashes the part, and writes the destination under the gateway's own encryption. * s3: fetch only the range a part copy asked for The re-encrypting UploadPartCopy path opened the source at offset 0 and threw the prefix away, so assembling an object part by part read the source once per part. Now that volume-encrypted sources take this path too, that is the common case rather than an SSE corner. The chunk stream already seeks, so hand it the range. * s3: reject an unsatisfiable copy-source-range A part copy has no way to report a short part, so a range reaching past the source cannot be clamped the way a GET clamps one. The fast path silently produced a part shorter than asked for, or an empty one; the re-encrypting path pads with zeros, so a 2 MiB source copied as bytes=1048576-9999999 came back as 1 MiB of data followed by 7.5 MiB of nothing. Answer InvalidRange instead, which is what s3-tests' test_multipart_copy_invalid_range expects.	2026-08-26 10:05:49 -07:00
Chris Lu	44115c1051	filer: stop TUS uploads from turning into garbage (#10945) ... * filer: store TUS sub-chunks through the regular chunk writer A TUS sub-chunk was written with one assigned file id, retried up to three times against that same id, and abandoned on failure: an attempt that had landed on some replicas left a needle no session record and no entry ever references, unreclaimable by vacuum. dataToChunkWithSSE, which the regular write path uses per chunk, assigns a fresh file id per attempt and hands back the file ids of failed attempts, which are now freed the way the regular write path frees them. * filer: retry a chunk write on a fresh volume when the server 5xxs The filer's chunk writer assigns a fresh file id per attempt but only retried transient network errors, so a volume filling up and turning read-only mid-write failed the whole request even though the very next assignment would have landed elsewhere. Every other write client already routes this through ShouldReassignUpload; the filer's own write path now does the same, for regular uploads and TUS sub-chunks alike. * filer: export the chunk deletion queue The filer test harness in weed/server builds filer.Filer as a struct literal, so any code path reaching DeleteChunks dereferenced a nil queue. Exported like the neighboring DeletionRetryQueue so the harness can arm it. * filer: complete a TUS upload whose chunk records overlap A PATCH retried while its predecessor was still storing a sub-chunk - a proxy timeout with an immediate retry is enough - records the same range twice. HEAD computes Upload-Offset as the covered watermark and reported the upload fully received, but completion demanded exactly adjacent records and failed every attempt: the client concluded success from offset == length, no entry was created, and the session eventually expired, turning the entire upload into deleted needles for the vacuum to chew through. Completion now validates gapless coverage with the same watermark HEAD uses. A record extending coverage joins the entry - the read path resolves partial overlaps by ModifiedTsNs, and the raced copies carry identical bytes - while a fully covered duplicate is freed once the entry lands. * filer: allow one mutating TUS request per session at a time Nothing stopped two PATCHes from writing the same range concurrently: both loaded the same offset, both passed the conflict check, and both recorded their sub-chunks. A client whose request timed out in a proxy retries immediately while the server side is still storing the buffered sub-chunk, which is exactly that race. A session now accepts one PATCH or DELETE at a time, the way tusd locks uploads; a concurrent one is refused with 423 Locked, which TUS clients retry, and HEAD keeps answering so progress polling is unaffected. The chunk state is loaded under the claim, so a retried PATCH sees every record its predecessor left and conflicts cleanly instead of duplicating data. * test: cover a TUS PATCH raced by its own retry Stalls a PATCH mid-body over a raw connection, retries the same range while it is in flight, and expects the retry refused with 423 Locked; the upload then resumes from the reported offset and the final content must be intact. * filer: never free a TUS duplicate the entry still references Coverage is computed from ranges, so a record fully covered by another is treated as a duplicate no matter which needle it names. A malformed record naming a file id the entry keeps would have had that needle freed right after the entry landed - the corruption this change set exists to stop. The duplicates are now freed in one batch, skipping any file id the entry references; their records go with the session directory. * test: bound the raw TUS connection reads http.ReadResponse on the stalled PATCH's connection blocked until the whole go test timeout if the filer never answered. * filer: free the needles of chunk write attempts a retry replaced A volume server stores the needle locally and only then fans out to the replicas, so a replication failure 5xxs with the data already written. Each attempt assigns its own file id, so once a later attempt lands elsewhere nothing references the earlier ones: the caller only sees the chunk that succeeded, and the failed ids were dropped. They are now freed the way the caller frees them when the whole write fails. Retrying on a 5xx makes this reachable on every read-only or full volume, which is exactly the condition that filled the reporter's volumes.	2026-08-25 09:24:51 -07:00
Chris Lu	e521a2a7b9	mount: re-assign to a live volume when a write can't land (#10239) ... With replication 001 and one node down, ~2/3 of volumes have their replica on the dead node. The primary write lands locally but the replica forward fails, so the volume returns 500 "failed to write to replicas". #9744 made that upload fail fast so the client re-assigns, but the client retry never fired: the reassign gate matched a fixed list of error substrings that didn't include this one. The mount surfaced I/O error and dropped the chunk, leaving missing lines and null-byte gaps in an append workload while a node rebooted. Decide reassignment by HTTP status instead of matching message text. On the write path a volume server only 5xxs on a ReplicatedWrite failure (local disk, replica peer down, under-replication) — all of which a different volume dodges — so any 5xx reassigns; a no-response transport failure (the assigned target itself is down) reassigns too; a 4xx is a genuine client error and is surfaced. doUploadData tags its errors with the response status via uploadStatusError, and the gate moves from util.MultiRetry(errList) to util.RetryOnError(predicate). This drops the fragile substring list (and the message-prefix constants and guard test it needed); store_replicate.go is untouched.	2026-07-06 11:41:26 -07:00

Chris Lu	95427b5573	security: add BearerPrefix constant for Authorization headers (#10101) ... Introduce security.BearerPrefix ("Bearer ", RFC 6750) and use it everywhere an "Authorization: Bearer <token>" header is constructed, replacing the scattered "BEARER "/"Bearer " string literals. SeaweedFS matches the scheme case-insensitively when parsing (security.GetJwt), so behavior is unchanged; this removes the magic string and settles the casing on the standard form. The parser's upper-case comparison stays as is on purpose.	2026-06-24 19:36:42 -07:00
Chris Lu	ef109fe9e1	mount: don't hang close() when a writer is killed during flush (#10090) ... * operation: bound AssignVolume with a deadline AssignVolume ran on context.Background(), so when the filer is overwhelmed the RPC could block indefinitely and wedge every caller holding the connection. Give it a 30s deadline so a stuck assign fails and the caller's retry/error path runs instead of hanging forever. * mount: abort flush when the FUSE request is interrupted On close(), a killed process blocks in fuse_flush waiting for the mount to answer. doFlush ran its metadata CreateEntry on context.Background() and ignored the kernel interrupt channel, so against an overwhelmed filer the flush never completed and the process stayed in uninterruptible sleep -- making the pod un-killable. Derive a context from the FUSE cancel channel in Flush/Fsync and thread it through doFlush -> flushMetadataToFiler -> streamCreateEntry; the retry loop stops as soon as the context is cancelled. Release and the pre-rename flush keep a non-cancellable context since they must finish regardless. * operation: harden the AssignVolume timeout test Make the test double's signal send non-blocking and bound the receive with a timeout so a regression can't wedge the test instead of failing it.	2026-06-24 14:24:22 -07:00
3 people	20e4614fc6	feat(mount): attach Content-MD5 to chunk uploads (#10016) ... * mount: attach Content-MD5 to chunk uploads Mount writes never set UploadOption.Md5, so FileChunk.ETag stays empty and filer.ETag() degenerates to md5("")-N: same-size files compare equal regardless of content, defeating metadata-level verification like filer.sync.verify. Compute each chunk's MD5 and send it as Content-MD5. The volume server verifies it on ingest (rejecting in-flight corruption) and echoes it back, persisting FileChunk.ETag like filer/S3 writes already do. The dirty-page flush paths already pass a *util.BytesReader whose backing slice is the whole chunk, so the digest is taken in place with no extra read, copy, or allocation (UploadWithRetry unwraps it the same way downstream). Only the rarer plain-reader callers (e.g. manifest chunks) fall back to io.ReadAll. Skipped under -cipher, where only the ciphertext reaches the server. The digest encoding (std-base64 of the raw md5) is the contract the volume server verifies against, so it is factored into contentMD5Base64 and covered by a unit test. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * mount: compute chunk Content-MD5 in the uploader, not the caller Move the WantMd5 hashing into UploadWithRetry, where the chunk is already buffered for the retry path, so saveDataAsChunk stops type-switching the reader and re-reading plain readers. One materialization point, and the cipher exclusion lives next to the hash instead of at every call site. --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Co-authored-by: Chris Lu <chris.lu@gmail.com>	2026-06-19 10:29:28 -07:00

Chris Lu	4bf27278fa	topology: fail replica writes fast when a replica is unreachable (#9744) ... * operation: bound upload retries and honor context cancellation retriedUploadData hardcoded 3 attempts and an uninterruptible backoff sleep. A synchronous replica write to a dead host therefore paid the full dial timeout three times over before failing. Add UploadOption.MaxAttempts (<=0 keeps the default of 3) so callers can cap attempts, and make the loop return as soon as the context is cancelled so an abandoned upload unwinds instead of retrying. * topology: fail replica writes fast when a replica is unreachable DistributedOperation already returns on the first error, but a single dead replica is itself the slow result: its goroutine retries the upload three times through the dial timeout (~30s) before any error surfaces, stalling the originating client write the whole time. Make the replica write a single attempt (MaxAttempts=1) so a dead replica fails after one dial timeout instead of three, and thread a context into DistributedOperation that is cancelled once the outcome is decided, so a healthy replica is no longer held hostage by one stalled in a dial. The originating client write is what retries. * topology: keep replica deletes off the client request context ReplicatedDelete runs after the local needle is already deleted. Driving the replica deletes off r.Context() means a client disconnect cancels them and orphans needles on the replicas, so use a background context. * operation, topology: trim comments on the replica fail-fast path	2026-05-30 10:45:02 -07:00
Chris Lu	0716577ec8	fix(upload): rewind request body when retrying on connection reset (#9139) (#9222) ... * fix(upload): rewind request body when retrying on connection reset (#9139) When httpClient.Do() returned "connection reset by peer" or "use of closed network connection", upload_content retried with the same *http.Request. But the body is a *bytes.Reader the first attempt already consumed, so the retry sent 0 bytes and Go's transport surfaced "http: ContentLength=N with Body length 0". http.NewRequestWithContext populates req.GetBody for *bytes.Reader bodies; use it to attach a fresh body before retrying. Reproduces the issue with a unit test (asserts both attempts see the same payload bytes); the test fails without the fix. * upload: skip inner retry when body cannot be rewound Per review feedback: if req.GetBody is nil or returns an error, the inner retry would call Do(req) with an already-consumed body and the "connection reset" error would be replaced by the misleading "ContentLength=N with Body length 0" — the very symptom this PR set out to fix. Skip the inner retry on rewind failure and let the outer retriedUploadData loop reissue with a fresh request, and log when GetBody is unavailable for observability. * upload: log the actual transport error in the inner retry log line Per review feedback: the diagnostic glog at the top of the inner retry branch was logging postErr — the request-construction error from http.NewRequestWithContext, which is necessarily nil there because the function returns early at line 423 if it isn't. Operators were seeing "<nil>" instead of the transient transport error that triggered the rewind. Reference post_err so the connection-reset / closed-connection cause is actually visible.	2026-04-26 02:17:55 -07:00

Chris Lu	00a2e22478	fix(mount): remove fid pool to stop master over-allocating volumes (#9111) ... * fix(mount): remove fid pool to stop master over-allocating volumes The writeback-cache fid pool pre-allocated file IDs with ExpectedDataSize = ChunkSizeLimit (typically 8+ MB). The master's PickForWrite charges count * expectedDataSize against the volume's effectiveSize, so a full pool refill could charge hundreds of MB against a single volume before any bytes were actually written. That tripped RecordAssign's hard-limit path and eagerly removed volumes from writable, causing the master to grow new volumes even when the real data being written was tiny. Drop the pool entirely. Every chunk upload goes through UploadWithRetry -> AssignVolume with no ExpectedDataSize hint, letting the master fall back to the 1 MB default estimate. The mount->filer grpc connection is already cached in pb.WithGrpcClient (non-streaming mode), so per-chunk AssignVolume is a unary RPC over an existing HTTP/2 stream, not a full dial. Path-based filer.conf storage rules now apply to mount chunk assigns again, which the pool had to skip. Also remove the now-unused operation.UploadWithAssignFunc and its AssignFunc type. * fix(upload): populate ExpectedDataSize from actual chunk bytes UploadWithRetry already buffers the full chunk into `data` before calling AssignVolume, so the real size is known. Previously the assign request went out with ExpectedDataSize=0, making the master fall back to the 1 MB DefaultNeedleSizeEstimate per fid — same over-reservation symptom the pool had, just smaller per call. Stamp ExpectedDataSize = len(data) before the assign RPC when the caller hasn't already set it. This covers mount chunk uploads, filer_copy, filersink, mq/logstore, broker_write, gateway_upload, and nfs — all the UploadWithRetry paths. * fix(assign): pass real ExpectedDataSize at every assign call site After removing the mount fid pool, per-chunk AssignVolume calls went out with ExpectedDataSize=0, making the master fall back to its 1 MB DefaultNeedleSizeEstimate. That's still an over-estimate for small writes. Thread the real payload size through every remaining assign site so RecordAssign charges effectiveSize accurately and stops prematurely marking volumes full. - filer: assignNewFileInfo now takes expectedDataSize and stamps it on both primary and alternate VolumeAssignRequests. Callers pass: - SSE data-to-chunk: len(data) - copy manifest save: len(data) - streamCopyChunk: srcChunk.Size - TUS sub-chunk: bytes read - saveAsChunk (autochunk/manifestize): 0 (small, size unknown until the reader is drained; master uses 1 MB default) - filer gRPC remote fetch-and-write: ExpectedDataSize = chunkSize after the adaptive chunkSize is computed. - ChunkedUploadOption.AssignFunc gains an expectedDataSize parameter; upload_chunked.go passes the buffered dataSize at the call site. S3 PUT assignFunc stamps it on the AssignVolumeRequest. - S3 copy: assignNewVolume / prepareChunkCopy take expectedDataSize; all seven call sites pass the source chunk's Size. - operation.SubmitFiles / FilePart.Upload: derive per-fid size from FileSize (average for batched requests, real per-chunk size for sequential chunk assigns). - benchmark: pass fileSize. - filer append-to-file: pass len(data). * fix(assign): thread size through SaveDataAsChunkFunctionType The saveAsChunk path (autochunk, filer_copy, webdav, mount) ran AssignVolume before the reader was drained, so it had to pass ExpectedDataSize=0 and fall back to the master's 1 MB default. Add an expectedDataSize parameter to SaveDataAsChunkFunctionType. - mergeIntoManifest already has the serialized manifest bytes, so it passes uint64(len(data)) directly. - Mount's saveDataAsChunk ignores the parameter because it uses UploadWithRetry, which already stamps len(data) on the assign after reading the payload. - webdav and filer_copy saveDataAsChunk follow the same UploadWithRetry path and also ignore the hint. - Filer's saveAsChunk (used for manifestize) plumbs the value to assignNewFileInfo so manifest-chunk assigns get a real size. Callers of saveFunc-as-value (weedfs_file_sync, dirty_pages_chunked) pass the chunk size they're about to upload.	2026-04-16 15:51:13 -07:00
Chris Lu	e8a8449553	feat(mount): pre-allocate file IDs in pool for writeback cache mode (#9038) ... * feat(mount): pre-allocate file IDs in pool for writeback cache mode When writeback caching is enabled, chunk uploads no longer block on a per-chunk AssignVolume RPC. Instead, a FileIdPool pre-allocates file IDs in batches using a single AssignVolume(Count=N, ExpectedDataSize=ChunkSize) call and hands them out instantly to upload workers. Pool size is 2x ConcurrentWriters, refilled in background when it drops below ConcurrentWriters. Entries expire after 25s to respect JWT TTL. Sequential needle keys are generated from the base file ID returned by the master, so one Assign RPC produces N usable IDs. This cuts per-chunk upload latency from 2 RTTs (assign + upload) to 1 RTT (upload only), with the assign cost amortized across the batch. * test: add benchmarks for file ID pool vs direct assign Benchmarks measure: - Pool Get vs Direct AssignVolume at various simulated latencies - Batch assign scaling (Count=1 through Count=32) - Concurrent pool access with 1-64 workers Results on Apple M4: - Pool Get: constant ~3ns regardless of assign latency - Batch=16: 15.7x more IDs/sec than individual assigns - 64 concurrent workers: 19M IDs/sec throughput * fix(mount): address review feedback on file ID pool 1. Fix race condition in Get(): use sync.Cond so callers wait for an in-flight refill instead of returning an error when the pool is empty. 2. Match default pool size to async flush worker count (128, not 16) when ConcurrentWriters is unset. 3. Add logging to UploadWithAssignFunc for consistency with UploadWithRetry. 4. Document that pooled assigns omit the Path field, bypassing path-based storage rules (filer.conf). This is an intentional tradeoff for writeback cache performance. 5. Fix flaky expiry test: widen time margin from 50ms to 1s. 6. Add TestFileIdPoolGetWaitsForRefill to verify concurrent waiters. * fix(mount): use individual Count=1 assigns to get per-fid JWTs The master generates one JWT per AssignResponse, bound to the base file ID (master_grpc_server_assign.go:158). The volume server validates that the JWT's Fid matches the upload exactly (volume_server_handlers.go:367). Using Count=N and deriving sequential IDs would fail this check. Switch to individual Count=1 RPCs over a single gRPC connection. This still amortizes connection overhead while getting a correct per-fid JWT for each entry. Partial batches are accepted if some requests fail. Remove unused needle import now that sequential ID generation is gone. * fix(mount): separate pprof from FUSE protocol debug logging The -debug flag was enabling both the pprof HTTP server and the noisy go-fuse protocol logging (rx/tx lines for every FUSE operation). This makes profiling impractical as the log output dominates. Split into two flags: - -debug: enables pprof HTTP server only (for profiling) - -debug.fuse: enables raw FUSE protocol request/response logging * perf(mount): replace LevelDB read+write with in-memory overlay for dir mtime Profile showed TouchDirMtimeCtime at 0.22s — every create/rename/unlink in a directory did a LevelDB FindEntry (read) + UpdateEntry (write) just to bump the parent dir's mtime/ctime. Replace with an in-memory map (same pattern as existing atime overlay): - touchDirMtimeCtimeLocal now stores inode→timestamp in dirMtimeMap - applyInMemoryDirMtime overlays onto GetAttr/Lookup output - No LevelDB I/O on the mutation hot path The overlay only advances timestamps forward (max of stored vs overlay), so stale entries are harmless. Map is bounded at 8192 entries. * perf(mount): skip self-originated metadata subscription events in writeback mode With writeback caching, this mount is the single writer. All local mutations are already applied to the local meta cache (via applyLocalMetadataEvent or direct InsertEntry). The filer subscription then delivers the same event back, causing redundant work: proto.Clone, enqueue to apply loop, dedup ring check, and sometimes redundant LevelDB writes when the dedup ring misses (deferred creates). Check EventNotification.Signatures against selfSignature and skip events that originated from this mount. This eliminates the redundant processing for every self-originated mutation. * perf(mount): increase kernel FUSE cache TTL in writeback cache mode With writeback caching, this mount is the single writer — the local meta cache is authoritative. Increase EntryValid and AttrValid from 1s to 10s so the kernel doesn't re-issue Lookup/GetAttr for every path component and stat call. This reduces FUSE /dev/fuse round-trips which dominate the profile at 38% of CPU (syscall.rawsyscalln). Each saved round-trip eliminates a kernel→userspace→kernel transition. Normal (non-writeback) mode retains the 1s TTL for multi-mount consistency.	2026-04-11 20:02:42 -07:00

Chris LuandCopilot	0647f66bb5	filer.sync: add exponential backoff on unexpected EOF during replication (#8557) ... * filer.sync: add exponential backoff on unexpected EOF during replication When the source volume server drops connections under high traffic, filer.sync retries aggressively (every 1-6s), hammering the already overloaded source. This adds a longer exponential backoff (10s to 2min) specifically for "unexpected EOF" errors, reducing pressure on the source while still retrying indefinitely until success. Also adds more logging throughout the replication path: - Log source URL and error at V(0) when ReadPart or io.ReadAll fails - Log content-length and byte counts at V(4) on success - Log backoff duration in retry messages Fixes #8542 * filer.sync: extract backoff helper and fix 2-minute cap - Extract nextEofBackoff() and isEofError() helpers to deduplicate the backoff logic between fetchAndWrite and uploadManifestChunk - Fix the cap: previously 80s would double to 160s and pass the < 2min check uncapped. Now doubles first, then clamps to 2min. * filer.sync: log source URL instead of empty upload URL on read errors UploadUrl is not populated until after the reader is consumed, so the V(0) and V(4) logs were printing an empty string. Add SourceUrl field to UploadOption and populate it from the HTTP response in fetchAndWrite. * filer.sync: guard isEofError against nil error * filer.sync: use errors.Is for EOF detection, fix log wording - Replace broad substring matching ("read input", "unexpected EOF") with errors.Is(err, io.ErrUnexpectedEOF) and errors.Is(err, io.EOF) so only actual EOF errors trigger the longer backoff - Fix awkward log phrasing: "interrupted replicate" → "interrupted while replicating" * filer.sync: remove EOF backoff from uploadManifestChunk uploadManifestChunk reads from an in-memory bytes.Reader, so any EOF errors there are from the destination side, not a broken source stream. The long source-oriented backoff is inappropriate; let RetryUntil handle destination retries at its normal cadence. --------- Co-authored-by: Copilot <copilot@github.com>	2026-03-08 14:33:37 -07:00

Chris Lu	c52d3d1229	fix: correct chunk size in encrypted uploads (fixes #8151) (#8154) ... * fix: correct chunk size in encrypted uploads When uploading with encryption enabled (-encryptVolumeData flag), the chunk metadata was incorrectly storing the encrypted data size instead of the original uncompressed size. This caused data corruption when reading files back because: 1. Encrypted data is larger than original data 2. After decryption and decompression, the actual data is smaller 3. Size validation in readEncryptedUrl would fail 4. Files appeared truncated with null bytes The fix ensures uploadResult.Size uses clearDataLen (the original uncompressed size) in both cipher and non-cipher code paths, matching the expected behavior. Fixes: #8151 * test: add comprehensive tests for encrypted upload size fix Add unit tests to verify that encrypted uploads correctly store the original uncompressed data size, not the encrypted size. Tests cover: - Cipher key generation and encryption/decryption roundtrip - Compression + encryption roundtrip with size preservation - Different data sizes - Compression detection and effectiveness - Size behavior demonstration showing the bug and fix All tests verify that metadata stores the original size (19 bytes in the key example) not the encrypted size (75 bytes), which is critical for preventing data corruption on read operations.

Chris Lu	8d6bcddf60	Add S3 volume encryption support with -s3.encryptVolumeData flag (#7890) ... * Add S3 volume encryption support with -s3.encryptVolumeData flag This change adds volume-level encryption support for S3 uploads, similar to the existing -filer.encryptVolumeData option. Each chunk is encrypted with its own auto-generated CipherKey when the flag is enabled. Changes: - Add -s3.encryptVolumeData flag to weed s3, weed server, and weed mini - Wire Cipher option through S3ApiServer and ChunkedUploadOption - Add integration tests for multi-chunk range reads with encryption - Tests verify encryption works across chunk boundaries Usage: weed s3 -encryptVolumeData weed server -s3 -s3.encryptVolumeData weed mini -s3.encryptVolumeData Integration tests: go test -v -tags=integration -timeout 5m ./test/s3/sse/... * Add GitHub Actions CI for S3 volume encryption tests - Add test-volume-encryption target to Makefile that starts server with -s3.encryptVolumeData - Add s3-volume-encryption job to GitHub Actions workflow - Tests run with integration build tag and 10m timeout - Server logs uploaded on failure for debugging * Fix S3 client credentials to use environment variables The test was using hardcoded credentials "any"/"any" but the Makefile sets AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY to "some_access_key1"/ "some_secret_key1". Updated getS3Client() to read from environment variables with fallback to "any"/"any" for manual testing. * Change bucket creation errors from skip to fatal Tests should fail, not skip, when bucket creation fails. This ensures that credential mismatches and other configuration issues are caught rather than silently skipped. * Make copy and multipart test jobs fail instead of succeed Changed exit 0 to exit 1 for s3-sse-copy-operations and s3-sse-multipart jobs. These jobs document known limitations but should fail to ensure the issues are tracked and addressed, not silently ignored. * Hardcode S3 credentials to match Makefile Changed from environment variables to hardcoded credentials "some_access_key1"/"some_secret_key1" to match the Makefile configuration. This ensures tests work reliably. * fix Double Encryption * fix Chunk Size Mismatch * Added IsCompressed * is gzipped * fix copying * only perform HEAD request when len(cipherKey) > 0 * Revert "Make copy and multipart test jobs fail instead of succeed" This reverts commit bc34a7eb3c. * fix security vulnerability * fix security * Update s3api_object_handlers_copy.go * Update s3api_object_handlers_copy.go * jwt to get content length	2025-12-27 00:09:14 -08:00

Clean, maintainable codebase with no function duplication - Consistent structured API usage throughout all bucket operations - Proper error handling and type safety - Build successful and all tests passing The bucket metadata system now has a completely clean, structured API without any conflicts, duplicates, or inconsistencies. * Update remaining functions to use new structured BucketMetadata APIs directly Updated functions to follow the pattern established in bucket config: - getEncryptionConfiguration() -> Uses GetBucketMetadata() directly - removeEncryptionConfiguration() -> Uses ClearBucketEncryption() directly Benefits: - Consistent API usage pattern across all bucket metadata operations - Simpler, more readable code that leverages the structured API - Eliminates calls to intermediate legacy functions - Better error handling and logging consistency - All tests pass with improved functionality This completes the transition to using the new structured BucketMetadata API throughout the entire bucket configuration and encryption subsystem. * Fix GitHub PR #7144 code review comments Address all code review comments from Gemini Code Assist bot: 1. **High Priority - SSE-KMS Key Validation**: Fixed ValidateSSEKMSKey to allow empty KMS key ID - Empty key ID now indicates use of default KMS key (consistent with AWS behavior) - Updated ParseSSEKMSHeaders to call validation after parsing - Enhanced isValidKMSKeyID to reject keys with spaces and invalid characters 2. **Medium Priority - KMS Registry Error Handling**: Improved error collection in CloseAll - Now collects all provider close errors instead of only returning the last one - Uses proper error formatting with %w verb for error wrapping - Returns single error for one failure, combined message for multiple failures 3. **Medium Priority - Local KMS Aliases Consistency**: Fixed alias handling in CreateKey - Now updates the aliases slice in-place to maintain consistency - Ensures both p.keys map and key.Aliases slice use the same prefixed format All changes maintain backward compatibility and improve error handling robustness. Tests updated and passing for all scenarios including edge cases. * Use errors.Join for KMS registry error handling Replace manual string building with the more idiomatic errors.Join function: - Removed manual error message concatenation with strings.Builder - Simplified error handling logic by using errors.Join(allErrors...) - Removed unnecessary string import - Added errors import for errors.Join This approach is cleaner, more idiomatic, and automatically handles: - Returning nil for empty error slice - Returning single error for one-element slice - Properly formatting multiple errors with newlines The errors.Join function was introduced in Go 1.20 and is the recommended way to combine multiple errors. * Update registry.go * Fix GitHub PR #7144 latest review comments Address all new code review comments from Gemini Code Assist bot: 1. **High Priority - SSE-KMS Detection Logic**: Tightened IsSSEKMSEncrypted function - Now relies only on the canonical x-amz-server-side-encryption header - Removed redundant check for x-amz-encrypted-data-key metadata - Prevents misinterpretation of objects with inconsistent metadata state - Updated test case to reflect correct behavior (encrypted data key only = false) 2. **Medium Priority - UUID Validation**: Enhanced KMS key ID validation - Replaced simplistic length/hyphen count check with proper regex validation - Added regexp import for robust UUID format checking - Regex pattern: ^[a-fA-F0-9]{8}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{12}$ - Prevents invalid formats like '------------------------------------' from passing 3. **Medium Priority - Alias Mutation Fix**: Avoided input slice modification - Changed CreateKey to not mutate the input aliases slice in-place - Uses local variable for modified alias to prevent side effects - Maintains backward compatibility while being safer for callers All changes improve code robustness and follow AWS S3 standards more closely. Tests updated and passing for all scenarios including edge cases. * Fix failing SSE tests Address two failing test cases: 1. **TestSSEHeaderConflicts**: Fixed SSE-C and SSE-KMS mutual exclusion - Modified IsSSECRequest to return false if SSE-KMS headers are present - Modified IsSSEKMSRequest to return false if SSE-C headers are present - This prevents both detection functions from returning true simultaneously - Aligns with AWS S3 behavior where SSE-C and SSE-KMS are mutually exclusive 2. **TestBucketEncryptionEdgeCases**: Fixed XML namespace validation - Added namespace validation in encryptionConfigFromXMLBytes function - Now rejects XML with invalid namespaces (only allows empty or AWS standard namespace) - Validates XMLName.Space to ensure proper XML structure - Prevents acceptance of malformed XML with incorrect namespaces Both fixes improve compliance with AWS S3 standards and prevent invalid configurations from being accepted. All SSE and bucket encryption tests now pass successfully. * Fix GitHub PR #7144 latest review comments Address two new code review comments from Gemini Code Assist bot: 1. **High Priority - Race Condition in UpdateBucketMetadata**: Fixed thread safety issue - Added per-bucket locking mechanism to prevent race conditions - Introduced bucketMetadataLocks map with RWMutex for each bucket - Added getBucketMetadataLock helper with double-checked locking pattern - UpdateBucketMetadata now uses bucket-specific locks to serialize metadata updates - Prevents last-writer-wins scenarios when concurrent requests update different metadata parts 2. **Medium Priority - KMS Key ARN Validation**: Improved robustness of ARN validation - Enhanced isValidKMSKeyID function to strictly validate ARN structure - Changed from 'len(parts) >= 6' to 'len(parts) != 6' for exact part count - Added proper resource validation for key/ and alias/ prefixes - Prevents malformed ARNs with incorrect structure from being accepted - Now validates: arn:aws:kms:region:account:key/keyid or arn:aws:kms:region:account:alias/aliasname Both fixes improve system reliability and prevent edge cases that could cause data corruption or security issues.

All SSE copy tests continue to pass. * reduce logs * Address PR comments: consolidate KMS validation & reduce debug logging 1. Create shared s3_validation_utils.go for consistent KMS key validation - Move isValidKMSKeyID from s3_sse_kms.go to shared utility - Ensures consistent validation across bucket encryption, object operations, and copy validation - Eliminates coupling between s3_bucket_encryption.go and s3_sse_kms.go - Provides comprehensive validation: rejects spaces, control characters, validates length 2.

Fix severe IV reuse vulnerability in SSE-S3 CTR mode encryption - Added calculateSSES3IVWithOffset function to ensure unique IVs per chunk/part - Updated CreateSSES3EncryptedReaderWithBaseIV to accept offset parameter - Prevents CTR mode IV reuse which could compromise confidentiality - Same secure approach as used in SSE-KMS implementation 🚀 FUNCTIONALITY FIXES: 2. Add missing SSE-S3 multipart upload support in PutObjectPartHandler - SSE-S3 multipart uploads now properly inherit encryption settings from CreateMultipartUpload - Added logic to check for SeaweedFSSSES3Encryption metadata in upload entry - Sets appropriate headers for putToFiler to handle SSE-S3 encryption - Mirrors existing SSE-KMS multipart implementation pattern 3. Fix incorrect SSE type tracking for SSE-S3 chunks - Changed from filer_pb.SSEType_NONE to filer_pb.SSEType_SSE_S3 - Ensures proper chunk metadata tracking and consistency - Eliminates confusion about encryption status of SSE-S3 chunks 🔧 LOGGING IMPROVEMENTS: 4. Reduce verbose debug logging in SSE-S3 detection - Changed glog.Infof to glog.V(4).Infof for debug messages - Prevents log flooding in production environments - Consistent with other debug logging patterns ✅ VERIFICATION: - All changes compile successfully - Basic S3 API tests pass - Security vulnerability eliminated with proper IV offset calculation - Multipart SSE-S3 uploads now properly supported - Chunk metadata correctly tagged with SSE-S3 type * Address code maintainability issues from PR review #7151 🔄 CODE DEDUPLICATION: 1. Eliminate duplicate IV calculation functions - Created shared s3_sse_utils.go with unified calculateIVWithOffset function - Removed duplicate calculateSSES3IVWithOffset from s3_sse_s3.go - Removed duplicate calculateIVWithOffset from s3_sse_kms.go - Both SSE-KMS and SSE-S3 now use the same proven IV offset calculation - Ensures consistent cryptographic behavior across all SSE implementations 📋 SHARED HEADER LOGIC IMPROVEMENT: 2. Refactor shouldSkipEncryptionHeader for better clarity - Explicitly identify shared headers (AmzServerSideEncryption) used by multiple SSE types - Separate SSE-specific headers from shared headers for clearer reasoning - Added isSharedSSEHeader, isSSECOnlyHeader, isSSEKMSOnlyHeader, isSSES3OnlyHeader - Improved logic flow: shared headers are contextually assigned to appropriate SSE types - Enhanced code maintainability and reduced confusion about header ownership 🎯 BENEFITS: - DRY principle: Single source of truth for IV offset calculation (40 lines → shared utility) - Maintainability: Changes to IV calculation logic now only need updates in one place - Clarity: Header filtering logic is now explicit about shared vs. specific headers - Consistency: Same cryptographic operations across SSE-KMS and SSE-S3 - Future-proofing: Easier to add new SSE types or shared headers ✅ VERIFICATION: - All code compiles successfully - Basic S3 API tests pass - No functional changes - purely structural improvements - Same security guarantees maintained with better organization * 🚨 CRITICAL FIX: Complete SSE-S3 multipart upload implementation - prevents data corruption ⚠️ CRITICAL BUG FIXED: The SSE-S3 multipart upload implementation was incomplete and would have caused data corruption for all multipart SSE-S3 uploads. Each part would be encrypted with a different key, making the final assembled object unreadable. 🔍 ROOT CAUSE: PutObjectPartHandler only set AmzServerSideEncryption header but did NOT retrieve and pass the shared base IV and key data that were stored during CreateMultipartUpload. This caused putToFiler to generate NEW encryption keys for each part instead of using the consistent shared key. ✅ COMPREHENSIVE SOLUTION: 1. **Added missing header constants** (s3_constants/header.go): - SeaweedFSSSES3BaseIVHeader: for passing base IV to putToFiler - SeaweedFSSSES3KeyDataHeader: for passing key data to putToFiler 2. **Fixed PutObjectPartHandler** (s3api_object_handlers_multipart.go): - Retrieve base IV from uploadEntry.Extended[SeaweedFSSSES3BaseIV] - Retrieve key data from uploadEntry.Extended[SeaweedFSSSES3KeyData] - Pass both to putToFiler via request headers - Added comprehensive error handling and logging for missing data - Mirrors the proven SSE-KMS multipart implementation pattern 3. **Enhanced putToFiler SSE-S3 logic** (s3api_object_handlers_put.go): - Detect multipart parts via presence of SSE-S3 headers - For multipart: deserialize provided key + use base IV with offset calculation - For single-part: maintain existing logic (generate new key + IV) - Use CreateSSES3EncryptedReaderWithBaseIV for consistent multipart encryption 🔐 SECURITY & CONSISTENCY: - Same encryption key used across ALL parts of a multipart upload - Unique IV per part using calculateIVWithOffset (prevents CTR mode vulnerabilities) - Proper base IV offset calculation ensures cryptographic security - Complete metadata serialization for storage and retrieval 📊 DATA FLOW FIX: Before: CreateMultipartUpload stores key/IV → PutObjectPart ignores → new key per part → CORRUPTED FINAL OBJECT After: CreateMultipartUpload stores key/IV → PutObjectPart retrieves → same key all parts → VALID FINAL OBJECT ✅ VERIFICATION: - All code compiles successfully - Basic S3 API tests pass - Follows same proven patterns as working SSE-KMS multipart implementation - Comprehensive error handling prevents silent failures This fix is essential for SSE-S3 multipart uploads to function correctly in production. * 🚨 CRITICAL FIX: Activate bucket default encryption - was completely non-functional ⚠️ CRITICAL BUG FIXED: Bucket default encryption functions were implemented but NEVER CALLED anywhere in the request handling pipeline, making the entire feature completely non-functional. Users setting bucket default encryption would expect automatic encryption, but objects would be stored unencrypted. 🔍 ROOT CAUSE: The functions applyBucketDefaultEncryption(), applySSES3DefaultEncryption(), and applySSEKMSDefaultEncryption() were defined in putToFiler but never invoked. No integration point existed to check for bucket defaults when no explicit encryption headers were provided. ✅ COMPLETE INTEGRATION: 1. **Added bucket default encryption logic in putToFiler** (lines 361-385): - Check if no explicit encryption was applied (SSE-C, SSE-KMS, or SSE-S3) - Call applyBucketDefaultEncryption() to check bucket configuration - Apply appropriate default encryption (SSE-S3 or SSE-KMS) if configured - Handle all metadata serialization for applied default encryption 2. **Automatic coverage for ALL upload types**: ✅ Regular PutObject uploads (PutObjectHandler) ✅ Versioned object uploads (putVersionedObject) ✅ Suspended versioning uploads (putSuspendedVersioningObject) ✅ POST policy uploads (PostPolicyHandler) ❌ Multipart parts (intentionally skip - inherit from CreateMultipartUpload) 3. **Proper response headers**: - Existing SSE type detection automatically includes bucket default encryption - PutObjectHandler already sets response headers based on returned sseType - No additional changes needed for proper S3 API compliance 🔄 AWS S3 BEHAVIOR IMPLEMENTED: - Bucket default encryption automatically applies when no explicit encryption specified - Explicit encryption headers always override bucket defaults (correct precedence) - Response headers correctly indicate applied encryption method - Supports both SSE-S3 and SSE-KMS bucket default encryption 📊 IMPACT: Before: Bucket default encryption = COMPLETELY IGNORED (major S3 compatibility gap) After: Bucket default encryption = FULLY FUNCTIONAL (complete S3 compatibility) ✅ VERIFICATION: - All code compiles successfully - Basic S3 API tests pass - Universal application through putToFiler ensures consistent behavior - Proper error handling prevents silent failures This fix makes bucket default encryption feature fully operational for the first time. * 🚨 CRITICAL SECURITY FIX: Fix insufficient error handling in SSE multipart uploads CRITICAL VULNERABILITY FIXED: Silent failures in SSE-S3 and SSE-KMS multipart upload initialization could lead to severe security vulnerabilities, specifically zero-value IV usage which completely compromises encryption security. ROOT CAUSE ANALYSIS: 1. Zero-value IV vulnerability (CRITICAL): - If rand.Read(baseIV) fails, IV remains all zeros - Zero IV in CTR mode = catastrophic crypto failure - All encrypted data becomes trivially decryptable 2. Silent key generation failure (HIGH): - If keyManager.GetOrCreateKey() fails, no encryption key stored - Parts upload without encryption while appearing to be encrypted - Data stored unencrypted despite SSE headers 3. Invalid serialization handling (MEDIUM): - If SerializeSSES3Metadata() fails, corrupted key data stored - Causes decryption failures during object retrieval - Silent data corruption with delayed failure COMPREHENSIVE FIXES APPLIED: 1. Proper error propagation pattern: - Added criticalError variable to capture failures within anonymous function - Check criticalError after mkdir() call and return s3err.ErrInternalError - Prevents silent failures that could compromise security 2. Fixed ALL critical crypto operations: ✅ SSE-S3 rand.Read(baseIV) - prevents zero-value IV ✅ SSE-S3 keyManager.GetOrCreateKey() - prevents missing encryption keys ✅ SSE-S3 SerializeSSES3Metadata() - prevents invalid key data storage ✅ SSE-KMS rand.Read(baseIV) - prevents zero-value IV (consistency fix) 3. Fail-fast security model: - Any critical crypto operation failure → immediate request termination - No partial initialization that could lead to security vulnerabilities - Clear error messages for debugging without exposing sensitive details SECURITY IMPACT: Before: Critical crypto vulnerabilities possible After: Cryptographically secure initialization guaranteed This fix prevents potential data exposure and ensures cryptographic security for all SSE multipart uploads. * 🚨 CRITICAL FIX: Address PR review issues from #7151 ⚠️ ADDRESSES CRITICAL AND MEDIUM PRIORITY ISSUES: 1. **CRITICAL: Fix IV storage for bucket default SSE-S3 encryption** - Problem: IV was stored in separate variable, not on SSES3Key object - Impact: Made decryption impossible for bucket default encrypted objects - Fix: Store IV directly on key.IV for proper decryption access 2. **MEDIUM: Remove redundant sseS3IV parameter** - Simplified applyBucketDefaultEncryption and applySSES3DefaultEncryption signatures - Removed unnecessary IV parameter passing since IV is now stored on key object - Cleaner, more maintainable API 3. **MEDIUM: Remove empty else block for code clarity** - Removed empty else block in filer_server_handlers_write_upload.go - Improves code readability and eliminates dead code 📊 DETAILED CHANGES: **weed/s3api/s3api_object_handlers_put.go**: - Updated applyBucketDefaultEncryption signature: removed sseS3IV parameter - Updated applySSES3DefaultEncryption signature: removed sseS3IV parameter - Added key.IV = iv assignment in applySSES3DefaultEncryption - Updated putToFiler call site: removed sseS3IV variable and parameter **weed/server/filer_server_handlers_write_upload.go**: - Removed empty else block (lines 314-315 in original) - Fixed missing closing brace for if r != nil block - Improved code structure and readability 🔒 SECURITY IMPACT: **Before Fix:** - Bucket default SSE-S3 encryption generated objects that COULD NOT be decrypted - IV was stored separately and lost during key retrieval process - Silent data loss - objects appeared encrypted but were unreadable **After Fix:** - Bucket default SSE-S3 encryption works correctly end-to-end - IV properly stored on key object and available during decryption - Complete functionality restoration for bucket default encryption feature ✅ VERIFICATION: - All code compiles successfully - Bucket encryption tests pass (TestBucketEncryptionAPIOperations, etc.) - No functional regressions detected - Code structure improved with better clarity These fixes ensure bucket default encryption is fully functional and secure, addressing critical issues that would have prevented successful decryption of encrypted objects. * 📝 MEDIUM FIX: Improve error message clarity for SSE-S3 serialization failures 🔍 ISSUE IDENTIFIED: Copy-paste error in SSE-S3 multipart upload error handling resulted in identical error messages for two different failure scenarios, making debugging difficult. 📊 BEFORE (CONFUSING): - Key generation failure: "failed to generate SSE-S3 key for multipart upload" - Serialization failure: "failed to serialize SSE-S3 key for multipart upload" ^^ SAME MESSAGE - impossible to distinguish which operation failed ✅ AFTER (CLEAR): - Key generation failure: "failed to generate SSE-S3 key for multipart upload" - Serialization failure: "failed to serialize SSE-S3 metadata for multipart upload" ^^ DISTINCT MESSAGE - immediately clear what failed 🛠️ CHANGE DETAILS: **weed/s3api/filer_multipart.go (line 133)**: - Updated criticalError message to be specific about metadata serialization - Changed from generic "key" to specific "metadata" to indicate the operation - Maintains consistency with the glog.Errorf message which was already correct 🔍 DEBUGGING BENEFIT: When multipart upload initialization fails, developers can now immediately identify whether the failure was in: 1. Key generation (crypto operation failure) 2. Metadata serialization (data encoding failure) This distinction is critical for proper error handling and debugging in production environments. ✅ VERIFICATION: - Code compiles successfully - All multipart tests pass (TestMultipartSSEMixedScenarios, TestMultipartSSEPerformance) - No functional impact - purely improves error message clarity - Follows best practices for distinct, actionable error messages This fix improves developer experience and production debugging capabilities. * 🚨 CRITICAL FIX: Fix IV storage for explicit SSE-S3 uploads - prevents unreadable objects ⚠️ CRITICAL VULNERABILITY FIXED: The initialization vector (IV) returned by CreateSSES3EncryptedReader was being discarded for explicit SSE-S3 uploads, making encrypted objects completely unreadable. This affected all single-part PUT operations with explicit SSE-S3 headers (X-Amz-Server-Side-Encryption: AES256). 🔍 ROOT CAUSE ANALYSIS: **weed/s3api/s3api_object_handlers_put.go (line 338)**: **IMPACT**: - Objects encrypted but IMPOSSIBLE TO DECRYPT - Silent data loss - encryption appeared successful - Complete feature non-functionality for explicit SSE-S3 uploads 🔧 COMPREHENSIVE FIX APPLIED: 📊 AFFECTED UPLOAD SCENARIOS: | Upload Type | Before Fix | After Fix | |-------------|------------|-----------| | **Explicit SSE-S3 (single-part)** | ❌ Objects unreadable | ✅ Full functionality | | **Bucket default SSE-S3** | ✅ Fixed in prev commit | ✅ Working | | **SSE-S3 multipart uploads** | ✅ Already working | ✅ Working | | **SSE-C/SSE-KMS uploads** | ✅ Unaffected | ✅ Working | 🔒 SECURITY & FUNCTIONALITY RESTORATION: **Before Fix:** - 💥 **Explicit SSE-S3 uploads = data loss** - objects encrypted but unreadable - 💥 **Silent failure** - no error during upload, failure during retrieval - 💥 **Inconsistent behavior** - bucket defaults worked, explicit headers didn't **After Fix:** - ✅ **Complete SSE-S3 functionality** - all upload types work end-to-end - ✅ **Proper IV management** - stored on key objects for reliable decryption - ✅ **Consistent behavior** - explicit headers and bucket defaults both work 🛠️ TECHNICAL IMPLEMENTATION: 1. **Capture IV from CreateSSES3EncryptedReader**: - Changed from discarding (_) to capturing (iv) the return value 2. **Store IV on key object**: - Added sseS3Key.IV = iv assignment - Ensures IV is included in metadata serialization 3. **Maintains compatibility**: - No changes to function signatures or external APIs - Consistent with bucket default encryption pattern ✅ VERIFICATION: - All code compiles successfully - All SSE tests pass (48 SSE-related tests) - Integration tests run successfully - No functional regressions detected - Fixes critical data accessibility issue This completes the SSE-S3 implementation by ensuring IVs are properly stored for ALL SSE-S3 upload scenarios, making the feature fully production-ready. * 🧪 ADD CRITICAL REGRESSION TESTS: Prevent IV storage bugs in SSE-S3 ⚠️ BACKGROUND - WHY THESE TESTS ARE NEEDED: The two critical IV storage bugs I fixed earlier were NOT caught by existing integration tests because the existing tests were too high-level and didn't verify the specific implementation details where the bugs existed. 🔍 EXISTING TEST ANALYSIS: - 10 SSE test files with 56 test functions existed - Tests covered component functionality but missed integration points - TestSSES3IntegrationBasic and TestSSES3BucketDefaultEncryption existed - BUT they didn't catch IV storage bugs - they tested overall flow, not internals 🎯 NEW REGRESSION TESTS ADDED: 1. **TestSSES3IVStorageRegression**: - Tests explicit SSE-S3 uploads (X-Amz-Server-Side-Encryption: AES256) - Verifies IV is properly stored on key object for decryption - Would have FAILED with original bug where IV was discarded in putToFiler - Tests multiple objects to ensure unique IV storage 2. **TestSSES3BucketDefaultIVStorageRegression**: - Tests bucket default SSE-S3 encryption (no explicit headers) - Verifies applySSES3DefaultEncryption stores IV on key object - Would have FAILED with original bug where IV wasn't stored on key - Tests multiple objects with bucket default encryption 3. **TestSSES3EdgeCaseRegression**: - Tests empty objects (0 bytes) with SSE-S3 - Tests large objects (1MB) with SSE-S3 - Ensures IV storage works across all object sizes 4. **TestSSES3ErrorHandlingRegression**: - Tests SSE-S3 with metadata and other S3 operations - Verifies integration doesn't break with additional headers 5. **TestSSES3FunctionalityCompletion**: - Comprehensive test of all SSE-S3 scenarios - Both explicit headers and bucket defaults - Ensures complete functionality after bug fixes 🔒 CRITICAL TEST CHARACTERISTICS: **Explicit Decryption Verification**: **Targeted Bug Detection**: - Tests the exact code paths where bugs existed - Verifies IV storage at metadata/key object level - Tests both explicit SSE-S3 and bucket default scenarios - Covers edge cases (empty, large objects) **Integration Point Testing**: - putToFiler() → CreateSSES3EncryptedReader() → IV storage - applySSES3DefaultEncryption() → IV storage on key object - Bucket configuration → automatic encryption application 📊 TEST RESULTS: ✅ All 4 new regression test suites pass (11 sub-tests total) ✅ TestSSES3IVStorageRegression: PASS (0.26s) ✅ TestSSES3BucketDefaultIVStorageRegression: PASS (0.46s) ✅ TestSSES3EdgeCaseRegression: PASS (0.46s) ✅ TestSSES3FunctionalityCompletion: PASS (0.25s) 🎯 FUTURE BUG PREVENTION: **What These Tests Catch**: - IV storage failures (both explicit and bucket default) - Metadata serialization issues - Key object integration problems - Decryption failures due to missing/corrupted IVs **Test Strategy Improvement**: - Added integration-point testing alongside component testing - End-to-end encrypt→store→retrieve→decrypt verification - Edge case coverage (empty, large objects) - Error condition testing 🔄 CI/CD INTEGRATION: These tests run automatically in the test suite and will catch similar critical bugs before they reach production. The regression tests complement existing unit tests by focusing on integration points and data flow. This ensures the SSE-S3 feature remains fully functional and prevents regression of the critical IV storage bugs that were fixed. * Clean up dead code: remove commented-out code blocks and unused TODO comments * 🔒 CRITICAL SECURITY FIX: Address IV reuse vulnerability in SSE-S3/KMS multipart uploads **VULNERABILITY ADDRESSED:** Resolved critical IV reuse vulnerability in SSE-S3 and SSE-KMS multipart uploads identified in GitHub PR review #3142971052. Using hardcoded offset of 0 for all multipart upload parts created identical encryption keystreams, compromising data confidentiality in CTR mode encryption. **CHANGES MADE:** 1. **Enhanced putToFiler Function Signature:** - Added partNumber parameter to calculate unique offsets for each part - Prevents IV reuse by ensuring each part gets a unique starting IV 2. **Part Offset Calculation:** - Implemented secure offset calculation: (partNumber-1) * 8GB - 8GB multiplier ensures no overlap between parts (S3 max part size is 5GB) - Applied to both SSE-S3 and SSE-KMS encryption modes 3. **Updated SSE-S3 Implementation:** - Modified putToFiler to use partOffset instead of hardcoded 0 - Enhanced CreateSSES3EncryptedReaderWithBaseIV calls with unique offsets 4. **Added SSE-KMS Security Fix:** - Created CreateSSEKMSEncryptedReaderWithBaseIVAndOffset function - Updated KMS multipart encryption to use unique IV offsets 5. **Updated All Call Sites:** - PutObjectPartHandler: passes actual partID for multipart uploads - Single-part uploads: use partNumber=1 for consistency - Post-policy uploads: use partNumber=1 **SECURITY IMPACT:** ✅ BEFORE: All multipart parts used same IV (critical vulnerability) ✅ AFTER: Each part uses unique IV calculated from part number (secure) **VERIFICATION:** ✅ All regression tests pass (TestSSES3.*Regression) ✅ Basic SSE-S3 functionality verified ✅ Both explicit SSE-S3 and bucket default scenarios tested ✅ Build verification successful **AFFECTED FILES:** - weed/s3api/s3api_object_handlers_put.go (main fix) - weed/s3api/s3api_object_handlers_multipart.go (part ID passing) - weed/s3api/s3api_object_handlers_postpolicy.go (call site update) - weed/s3api/s3_sse_kms.go (SSE-KMS offset function added) This fix ensures that the SSE-S3 and SSE-KMS multipart upload implementations are cryptographically secure and prevent IV reuse attacks in CTR mode encryption. * ♻️ REFACTOR: Extract crypto constants to

Crypto/rand Usage Already Explicit** ✅ • Verified filer_multipart.go correctly imports crypto/rand (not math/rand) • All rand.Read() calls use cryptographically secure implementation • No changes needed - already following security best practices 🎯 Benefits: • Code Clarity: Eliminated confusing pointer parameter modifications • Maintainability: Constants make validation limits explicit and configurable • Testability: Return-based functions easier to unit test in isolation • Security: Verified cryptographically secure random number generation • Standards: Follows Go best practices for function design ✅ Quality: All 54+ SSE unit tests pass successfully 🎯 Impact: Improved code maintainability and readability Addresses Copilot AI code quality review comments: https://github.com/seaweedfs/seaweedfs/pull/7151#pullrequestreview-3143338544 * format * 🔧 FIX: Correct AWS S3 multipart upload part number validation ✨ Problem Addressed (Copilot AI Issue): • Part validation was allowing up to 100,000 parts vs AWS S3 limit of 10,000 • Missing explicit validation warning users about the 10,000 part limit • Inconsistent error types between part validation scenarios 🔧 Solution Implemented: **1. Fix Incorrect Part Limit Constant** ✅ • Corrected globalMaxPartID from 100000 → 10000 (matches AWS S3 specification) • Added MaxS3MultipartParts = 10000 constant to s3_constants/crypto.go • Consolidated multipart limits with other S3 service constraints **2. Updated Part Number Validation** ✅ • Updated PutObjectPartHandler to use s3_constants.MaxS3MultipartParts • Updated CopyObjectPartHandler to use s3_constants.MaxS3MultipartParts • Changed error type from ErrInvalidMaxParts → ErrInvalidPart for consistency • Removed obsolete globalMaxPartID constant definition **3. Consistent Error Handling** ✅ • Both regular and copy part handlers now use ErrInvalidPart for part number validation • Aligned with AWS S3 behavior for invalid part number responses • Maintains existing validation for partID < 1 (already correct) 🎯 Benefits: • AWS S3 Compliance: Enforces correct 10,000 part limit per AWS specification • Security: Prevents resource exhaustion from excessive part numbers • Consistency: Unified validation logic across multipart upload and copy operations • Constants: Better maintainability with centralized S3 service constraints • Error Clarity: Consistent error responses for all part number validation failures ✅ Quality: All 54+ SSE unit tests pass successfully 🎯 Impact: Critical AWS S3 compliance fix for multipart upload validation Addresses Copilot AI validation concern: AWS S3 allows maximum 10,000 parts in a multipart upload, not 100,000 * 📚 REFACTOR: Extract SSE-S3 encryption helper functions for better readability ✨ Problem Addressed (Copilot AI Nitpick): • handleSSES3Encryption function had high complexity with nested conditionals • Complex multipart upload logic (lines 134-168) made function hard to read and maintain • Single monolithic function handling two distinct scenarios (single-part vs multipart) 🔧 Solution Implemented: **1. Extracted Multipart Logic** ✅ • Created handleSSES3MultipartEncryption() for multipart upload scenarios • Handles key data decoding, base IV processing, and offset-aware encryption • Clear single-responsibility function with focused error handling **2. Extracted Single-Part Logic** ✅ • Created handleSSES3SinglePartEncryption() for single-part upload scenarios • Handles key generation, IV creation, and key storage • Simplified function signature without unused parameters **3. Simplified Main Function** ✅ • Refactored handleSSES3Encryption() to orchestrate the two helper functions • Reduced from 70+ lines to 35 lines with clear decision logic • Eliminated deeply nested conditionals and improved readability **4. Improved Code Organization** ✅ • Each function now has single responsibility (SRP compliance) • Better error propagation with consistent s3err.ErrorCode returns • Enhanced maintainability through focused, testable functions 🎯 Benefits: • Readability: Complex nested logic now split into focused functions • Maintainability: Each function handles one specific encryption scenario • Testability: Smaller functions are easier to unit test in isolation • Reusability: Helper functions can be used independently if needed • Debugging: Clearer stack traces with specific function names • Code Review: Easier to review smaller, focused functions ✅ Quality: All 54+ SSE unit tests pass successfully 🎯 Impact: Significantly improved code readability without functional changes Addresses Copilot AI complexity concern: Function had high complexity with nested conditionals - now properly factored * 🏷️ RENAME: Change sse_kms_metadata to sse_metadata for clarity ✨ Problem Addressed: • Protobuf field sse_kms_metadata was misleading - used for ALL SSE types, not just KMS • Field name suggested KMS-only usage but actually stored SSE-C, SSE-KMS, and SSE-S3 metadata • Code comments and field name were inconsistent with actual unified metadata usage 🔧 Solution Implemented: **1. Updated Protobuf Schema** ✅ • Renamed field from sse_kms_metadata → sse_metadata • Updated comment to clarify: 'Serialized SSE metadata for this chunk (SSE-C, SSE-KMS, or SSE-S3)' • Regenerated protobuf Go code with correct field naming **2. Updated All Code References** ✅ • Updated 29 references across all Go files • Changed SseKmsMetadata → SseMetadata (struct field) • Changed GetSseKmsMetadata() → GetSseMetadata() (getter method) • Updated function parameters: sseKmsMetadata → sseMetadata • Fixed parameter references in function bodies **3. Preserved Unified Metadata Pattern** ✅ • Maintained existing behavior: one field stores all SSE metadata types • SseType field still determines how to deserialize the metadata • No breaking changes to the unified metadata storage approach • All SSE functionality continues to work identically 🎯 Benefits: • Clarity: Field name now accurately reflects its unified purpose • Documentation: Comments clearly indicate support for all SSE types • Maintainability: No confusion about what metadata the field contains • Consistency: Field name aligns with actual usage patterns • Future-proof: Clear naming for additional SSE types ✅ Quality: All 54+ SSE unit tests pass successfully 🎯 Impact: Better code clarity without functional changes This change eliminates the misleading KMS-specific naming while preserving the proven unified metadata storage architecture. * Update weed/s3api/s3api_object_handlers_multipart.go Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update weed/s3api/s3api_object_handlers_copy.go Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Fix Copilot AI code quality suggestions: hasExplicitEncryption helper and SSE-S3 validation order * Update weed/s3api/s3api_object_handlers_multipart.go Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update weed/s3api/s3api_put_handlers.go Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> * Update weed/s3api/s3api_object_handlers_copy.go Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com> --------- Co-authored-by: gemini-code-assist[bot] <176961590+gemini-code-assist[bot]@users.noreply.github.com> Co-authored-by: Copilot <175728472+Copilot@users.noreply.github.com>	2025-08-22 01:15:42 -07:00

Proper error handling with better granularity - All tests passing and build successful The bucket metadata system now uses a unified, type-safe, structured API that supports tags, CORS, and encryption configuration consistently. * Fix updateEncryptionConfiguration for first-time bucket encryption setup - Change getBucketEncryptionMetadata to getBucketMetadata to avoid failures when no encryption config exists - Change setBucketEncryptionMetadata to setBucketMetadataWithEncryption for consistency - This fixes the critical issue where bucket encryption configuration failed for buckets without existing encryption Fixes: https://github.com/seaweedfs/seaweedfs/pull/7144#discussion_r2285669572 * Fix rebase conflicts and maintain structured BucketMetadata API Resolved Conflicts: - Fixed merge conflicts in s3api_bucket_config.go between structured API (HEAD) and old intermediate functions - Kept modern structured API approach: UpdateBucketCORS, ClearBucketCORS, UpdateBucketEncryption - Removed old intermediate functions: setBucketTags, deleteBucketTags, setBucketMetadataWithEncryption API Consistency Maintained: - updateCORSConfiguration: Uses UpdateBucketCORS() directly - removeCORSConfiguration: Uses ClearBucketCORS() directly - updateEncryptionConfiguration: Uses UpdateBucketEncryption() directly - All structured API functions preserved: GetBucketMetadata, SetBucketMetadata, UpdateBucketMetadata Benefits: - Maintains clean separation between API layers - Preserves atomic metadata updates with proper error handling - Eliminates function indirection for better performance - Consistent API usage pattern throughout codebase - All tests passing and build successful The bucket metadata system continues to use the unified, type-safe, structured API that properly handles tags, CORS, and encryption configuration without any intermediate wrapper functions. * Fix complex rebase conflicts and maintain clean structured BucketMetadata API Resolved Complex Conflicts: - Fixed merge conflicts between modern structured API (HEAD) and mixed approach - Removed duplicate function declarations that caused compilation errors - Consistently chose structured API approach over intermediate functions Fixed Functions: - BucketMetadata struct: Maintained clean field alignment - loadCORSFromBucketContent: Uses GetBucketMetadata() directly - updateCORSConfiguration: Uses UpdateBucketCORS() directly - removeCORSConfiguration: Uses ClearBucketCORS() directly - getBucketMetadata: Returns *BucketMetadata struct consistently - setBucketMetadata: Accepts *BucketMetadata struct consistently Removed Duplicates: - Eliminated duplicate GetBucketMetadata implementations -

Single, unified BucketMetadata struct for all operations - Atomic updates through UpdateBucketMetadata with function callbacks - Type-safe operations with proper error handling - No intermediate wrapper functions cluttering the API Benefits: - Clean, maintainable codebase with no function duplication - Consistent structured API usage throughout all bucket operations - Proper error handling and type safety - Build successful and all tests passing The bucket metadata system now has a completely clean, structured API without any conflicts, duplicates, or inconsistencies. * Update remaining functions to use new structured BucketMetadata APIs directly Updated functions to follow the pattern established in bucket config: - getEncryptionConfiguration() -> Uses GetBucketMetadata() directly - removeEncryptionConfiguration() -> Uses ClearBucketEncryption() directly Benefits: - Consistent API usage pattern across all bucket metadata operations - Simpler, more readable code that leverages the structured API - Eliminates calls to intermediate legacy functions - Better error handling and logging consistency - All tests pass with improved functionality This completes the transition to using the new structured BucketMetadata API throughout the entire bucket configuration and encryption subsystem. * Fix GitHub PR #7144 code review comments Address all code review comments from Gemini Code Assist bot: 1. **High Priority - SSE-KMS Key Validation**: Fixed ValidateSSEKMSKey to allow empty KMS key ID - Empty key ID now indicates use of default KMS key (consistent with AWS behavior) - Updated ParseSSEKMSHeaders to call validation after parsing - Enhanced isValidKMSKeyID to reject keys with spaces and invalid characters 2. **Medium Priority - KMS Registry Error Handling**: Improved error collection in CloseAll - Now collects all provider close errors instead of only returning the last one - Uses proper error formatting with %w verb for error wrapping - Returns single error for one failure, combined message for multiple failures 3. **Medium Priority - Local KMS Aliases Consistency**: Fixed alias handling in CreateKey - Now updates the aliases slice in-place to maintain consistency - Ensures both p.keys map and key.Aliases slice use the same prefixed format All changes maintain backward compatibility and improve error handling robustness. Tests updated and passing for all scenarios including edge cases. * Use errors.Join for KMS registry error handling Replace manual string building with the more idiomatic errors.Join function: - Removed manual error message concatenation with strings.Builder - Simplified error handling logic by using errors.Join(allErrors...) - Removed unnecessary string import - Added errors import for errors.Join This approach is cleaner, more idiomatic, and automatically handles: - Returning nil for empty error slice - Returning single error for one-element slice - Properly formatting multiple errors with newlines The errors.Join function was introduced in Go 1.20 and is the recommended way to combine multiple errors. * Update registry.go * Fix GitHub PR #7144 latest review comments Address all new code review comments from Gemini Code Assist bot: 1. **High Priority - SSE-KMS Detection Logic**: Tightened IsSSEKMSEncrypted function - Now relies only on the canonical x-amz-server-side-encryption header - Removed redundant check for x-amz-encrypted-data-key metadata - Prevents misinterpretation of objects with inconsistent metadata state - Updated test case to reflect correct behavior (encrypted data key only = false) 2. **Medium Priority - UUID Validation**: Enhanced KMS key ID validation - Replaced simplistic length/hyphen count check with proper regex validation - Added regexp import for robust UUID format checking - Regex pattern: ^[a-fA-F0-9]{8}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{12}$ - Prevents invalid formats like '------------------------------------' from passing 3. **Medium Priority - Alias Mutation Fix**: Avoided input slice modification - Changed CreateKey to not mutate the input aliases slice in-place - Uses local variable for modified alias to prevent side effects - Maintains backward compatibility while being safer for callers All changes improve code robustness and follow AWS S3 standards more closely. Tests updated and passing for all scenarios including edge cases. * Fix failing SSE tests Address two failing test cases: 1. **TestSSEHeaderConflicts**: Fixed SSE-C and SSE-KMS mutual exclusion - Modified IsSSECRequest to return false if SSE-KMS headers are present - Modified IsSSEKMSRequest to return false if SSE-C headers are present - This prevents both detection functions from returning true simultaneously - Aligns with AWS S3 behavior where SSE-C and SSE-KMS are mutually exclusive 2. **TestBucketEncryptionEdgeCases**: Fixed XML namespace validation - Added namespace validation in encryptionConfigFromXMLBytes function - Now rejects XML with invalid namespaces (only allows empty or AWS standard namespace) - Validates XMLName.Space to ensure proper XML structure - Prevents acceptance of malformed XML with incorrect namespaces Both fixes improve compliance with AWS S3 standards and prevent invalid configurations from being accepted. All SSE and bucket encryption tests now pass successfully. * Fix GitHub PR #7144 latest review comments Address two new code review comments from Gemini Code Assist bot: 1. **High Priority - Race Condition in UpdateBucketMetadata**: Fixed thread safety issue - Added per-bucket locking mechanism to prevent race conditions - Introduced bucketMetadataLocks map with RWMutex for each bucket - Added getBucketMetadataLock helper with double-checked locking pattern - UpdateBucketMetadata now uses bucket-specific locks to serialize metadata updates - Prevents last-writer-wins scenarios when concurrent requests update different metadata parts 2. **Medium Priority - KMS Key ARN Validation**: Improved robustness of ARN validation - Enhanced isValidKMSKeyID function to strictly validate ARN structure - Changed from 'len(parts) >= 6' to 'len(parts) != 6' for exact part count - Added proper resource validation for key/ and alias/ prefixes - Prevents malformed ARNs with incorrect structure from being accepted - Now validates: arn:aws:kms:region:account:key/keyid or arn:aws:kms:region:account:alias/aliasname Both fixes improve system reliability and prevent edge cases that could cause data corruption or security issues.
