server: skip default local unix sockets that cannot be bound
weed server fatally exited during S3, filer, or SFTP startup when the default /tmp/seaweedfs-<svc>-<port>.sock path could not be removed or bound. On shared hosts (e.g. CI runners where another user's weed left a socket in the sticky /tmp directory) a stale socket file turns into 'operation not permitted' and kills the whole server, even though the TCP listeners are unaffected. Warn and skip the unix socket listener instead, matching how the gRPC local socket already degrades. An explicitly configured -localSocket path still fails fast, since a co-located S3 server may be configured to dial the filer through it.
* ip.bind: bind outbound connections to the configured address
-ip.bind only governed listeners; outbound gRPC and HTTP connections let
the OS pick the source IP, which may not even be able to reach the
target. Mirror the bind address into a process-global source address and
apply it to outbound TCP dials: the gRPC context dialer, the per-client
HTTP transports, and the default transport. Loopback targets and unix
sockets keep the OS-chosen source so same-host traffic still works.
* ip.bind: first-write-wins source IP, skip on address-family mismatch
Make SetOutboundLocalIP first-write-wins so a `weed server` component's own
bind setting (run in its goroutine) can't clobber the process-wide source
address the top-level -ip.bind already established for the other components.
Skip source binding when the target is a literal IP of a different family
than the bind address, since forcing a mismatched source fails the dial.
* sftpd: support SSH user certificates signed by a trusted CA
Adds a new "certificate" auth method to weed sftp. When enabled, the server
loads trusted CA public keys from -trustedUserCAKeysFile (OpenSSH
authorized_keys format, one or more keys) and accepts only ssh.Certificate
blobs of type UserCert on the public-key channel. Validation uses
ssh.CertChecker: CA signature, ValidAfter/ValidBefore, non-empty
ValidPrincipals and SSH login user must appear in ValidPrincipals. The
authenticated user must exist in the user store; home dir and permissions
resolve as before.
Behaviour mirrors MinIO's --sftp=trusted-user-ca-key and OpenSSH's
TrustedUserCAKeys: when certificate auth is active, plain (non-cert) public
keys are rejected even if "publickey" is also listed. Default authMethods
remain "password,publickey", so existing deployments are unaffected.
* Update weed/sftpd/auth/certificate.go

* sftpd: address review feedback on certificate auth
- Pre-marshal trusted CA public keys in IsUserAuthority instead of
re-marshaling on every authentication attempt (gemini-code-assist).
- Differentiate user-not-found from underlying store errors via
errors.As(*user.UserNotFoundError) so backend/read failures are no
longer reported as bad credentials (coderabbitai).
- Fix the corresponding sanity check in the missing-file test to use
errors.As instead of errors.Is (UserNotFoundError has no Is method,
so the previous check never matched) (coderabbitai).
* sftpd: register trustedUserCAKeysFile flag in filer and server commands
The new field on SftpOptions is dereferenced unconditionally in
resolvePaths(), but only the standalone `weed sftp` command was wiring
its flag. `weed filer` and `weed server` both embed an SftpOptions value
and call resolvePaths() on it, so they hit a nil pointer dereference at
startup.
Register `-sftp.trustedUserCAKeysFile` in both commands and update the
-sftp.authMethods help text to mention the new "certificate" method.
Fixes the SFTP Integration Tests CI failure on this PR.
* helm: expose SFTP certificate auth in the SeaweedFS chart
Adds Helm-chart support for the new SSH user-certificate auth method:
- values.yaml (sftp:) gains `trustedUserCAKeys` (inline OpenSSH
authorized_keys-format CA public keys) and `existingCAKeysSecret`
(reference an externally managed Secret). Same pair added under
allInOne.sftp with a null default that falls back to the top-level
sftp.* setting.
- New template templates/sftp/sftp-ca-secret.yaml renders a
chart-managed Secret <release>-sftp-ca-secret with `ca_user.pub`,
but only when SFTP is enabled, "certificate" is in authMethods,
inline keys are provided, and no existingCAKeysSecret is set.
- templates/sftp/sftp-deployment.yaml and the all-in-one deployment
template add `-trustedUserCAKeysFile=/etc/sw/sftp_ca/ca_user.pub`
to the weed sftp command, mount the CA secret at /etc/sw/sftp_ca
and add the corresponding volume. All cert-auth bits are guarded
by `contains "certificate" authMethods` so existing users see no
change.
- authMethods help text updated to mention "certificate".
Verified end-to-end on a local k3d cluster: cert login succeeds,
plain-pubkey login is rejected with "public key without certificate
not allowed".
* helm: fail render when SFTP certificate auth lacks CA keys
When certificate is in authMethods but neither trustedUserCAKeys nor
existingCAKeysSecret is set, the deployment mounted a secret that the
chart never renders, leaving the pod stuck on a missing volume. Fail at
template time with a clear message instead.
* sftpd: fix stale auth-method list in SFTPServiceOptions comment
keyboard-interactive was never implemented; certificate is the new
supported method. Match the CLI help text.
* sftpd: test Manager wiring of certificate vs public-key channel
Cover the channel takeover at the Manager level: certificate auth
displaces plain public-key auth when both are enabled, public-key auth
stays put otherwise, and enabling certificate without a CA file errors.

* refactor(command): expand "~" in all path-style CLI flags
Many of weed's path-bearing flags (-s3.config, -s3.iam.config,
-admin.dataDir, -webdav.cacheDir, -volume.dir.idx, TLS cert/key
files, profile output paths, mount cache dirs, sftp key files, ...)
were never run through util.ResolvePath, so a value like "~/iam.json"
was used literally. Tilde only worked when the shell expanded it,
which silently fails for the common -flag=~/path form (bash leaves
the tilde literal in --opt=~/path).
- Extend util.ResolvePath to also handle "~user" / "~user/rest",
matching shell tilde expansion. Add unit tests.
- Apply util.ResolvePath at the top of each shared start* function
(s3, webdav, sftp) so mini/server/filer/standalone callers all
inherit it; resolve at the few one-off use sites (mount cache
dirs, volume idx folder, mini admin.dataDir, profile paths).
- Drop the duplicate expandHomeDir helper from admin.go in favor of
the now-equivalent util.ResolvePath.
* fixup: handle comma-separated -dir flags for tilde expansion
`weed mini -dir`, `weed server -dir`, and `weed volume -dir` accept
comma-separated paths (`dir[,dir]...`). Calling util.ResolvePath on
the whole string mishandled multi-folder values with tilde, e.g.
"~/d1,~/d2" would resolve as if "d1,~/d2" were a single subpath.
- Add util.ResolveCommaSeparatedPaths: split on ",", run each entry
through ResolvePath, rejoin. Short-circuits when no "~" present.
- Use it for *miniDataFolders (mini.go), *volumeDataFolders (server.go),
and resolve each entry of v.folders in-place (volume.go) so all
downstream consumers see resolved paths.
- Add 7-case TestResolveCommaSeparatedPaths covering empty, single,
multiple, and mixed inputs.
* address PR review: metaFolder + Windows backslash
- master.go: resolve *m.metaFolder at the top of runMaster so
util.FullPath(*m.metaFolder) on the next line sees an expanded
path. Drop the now-redundant ResolvePath in TestFolderWritable.
- server.go: same treatment for *masterOptions.metaFolder, paired
with the existing cpu/mem profile resolves. Drop the redundant
inner ResolvePath at TestFolderWritable.
- file_util.go: ResolvePath now accepts filepath.Separator as a
separator after the tilde, so "~\\data" works on Windows. Other
platforms keep current behaviour (backslash stays literal because
it is a valid filename character in usernames and paths).
- file_util_test.go: add two cases using filepath.Separator that
exercise the new code path on Windows and remain a no-op on Unix.
* address PR review: resolve "~" in remaining command path flags
Comprehensive sweep of path-bearing flags across every weed
subcommand, applying util.ResolvePath in-place at the top of each
run* function so all downstream consumers see expanded paths.
- webdav.go: resolve *wo.cacheDir at the top of startWebDav so
mini/server/filer/standalone callers all inherit it.
- mount_std.go: cpu/mem profile paths.
- filer_sync.go: cpu/mem profile paths.
- mq_broker.go: cpu/mem profile paths.
- benchmark.go: cpuprofile output path.
- backup.go: -dir resolved once at runBackup; drop the duplicated
inline ResolvePath in NewVolume calls.
- compact.go: -dir resolved at runCompact; drop inline ResolvePath.
- export.go: -dir and -o resolved at runExport; drop inline
ResolvePath in LoadFromIdx and ScanVolumeFile.
- download.go: -dir resolved at runDownload; drop inline.
- update.go: -dir resolved at runUpdate so filepath.Join uses the
expanded path; drop inline ResolvePath in TestFolderWritable.
- scaffold.go: -output expanded before filepath.Join.
- worker.go: -workingDir expanded before being passed to runtime.
* address PR review: resolve option-struct paths at run* entry points
server.go:381 propagates s3Options.config to filerOptions.s3ConfigFile
*before* startS3Server runs, which meant the filer-side code saw the
unresolved tilde-prefixed pointer. Same pattern for webdavOptions and
sftpOptions (and equivalent in mini.go / filer.go).
The fix: hoist resolution from the shared start* functions up to the
run* entry points, where every shared pointer is set up before any
propagation happens.
- s3.go, webdav.go, sftp.go: extract a resolvePaths() method on each
Options struct that runs every path field through util.ResolvePath
in-place. Idempotent.
- runS3, runWebDav, runSftp: call the standalone struct's resolvePaths
before starting metrics / loading security config.
- runServer, runMini, runFiler: call resolvePaths on every embedded
options struct, plus resolve loose flags (serverIamConfig,
miniS3Config, miniIamConfig, miniMasterOptions.metaFolder, and
filer's defaultLevelDbDirectory) so they're expanded before any
pointer copy or use.
- Drop the now-redundant inline ResolvePath at filer's
defaultLevelDbDirectory composition.
* address PR review: re-resolve mini -dir post-config, cover misc paths
- mini.go: applyConfigFileOptions can overwrite -dir with a literal
~/data from mini.options. Re-resolve *miniDataFolders after the
config-file apply, alongside the other path resolves, so the mini
filer no longer ends up with a literal ~/data/filerldb2.
- benchmark.go: resolve *b.idListFile (-list).
- filer_sync.go: resolve *syncOptions.aSecurity / .bSecurity
(-a.security / -b.security) before LoadClientTLSFromFile.
- filer_cat.go: resolve *filerCat.output (-o) before os.OpenFile.
- admin.go: drop trailing blank line at EOF (git diff --check).
* address PR review: resolve -a.security/-b.security/-config before use
Three follow-up fixes:
- filer_sync.go: the -a.security / -b.security resolves were placed
*after* LoadClientTLSFromFile / LoadHTTPClientFromFile were called,
so weed filer.sync -a.security=~/a.toml still passed the literal
tilde path. Hoist the resolves above the security-loading block so
TLS clients see expanded paths.
- filer_sync_verify.go: same flag pair was never resolved at all in
the verify command; resolve at the top of runFilerSyncVerify.
- filer_meta_backup.go: -config (the backup_filer.toml path) was
passed directly to viper. Resolve at the top of runFilerMetaBackup.
- mini.go: master.dir defaulted to the entire comma-joined
miniDataFolders. With weed mini -dir=~/d1,~/d2 (or any multi-dir
setup), TestFolderWritable then stat'd the joined string instead
of a single directory. Default to the first entry via StringSplit
to mirror the disk-space calculation a few lines below, and drop
the now-redundant ResolvePath in TestFolderWritable.
* Fix SFTP file upload failures with JWT filer tokens (issue #8425)
When JWT authentication is enabled for filer operations via jwt.filer_signing.*
configuration, SFTP server file upload requests were rejected because they lacked
JWT authorization headers.
Changes:
- Added JWT signing key and expiration fields to SftpServer struct
- Modified putFile() to generate and include JWT tokens in upload requests
- Enhanced SFTPServiceOptions with JWT configuration fields
- Updated SFTP command startup to load and pass JWT config to service
This allows SFTP uploads to authenticate with JWT-enabled filers, consistent
with how other SeaweedFS components (S3 API, file browser) handle filer auth.
Fixes#8425

Fixes#7650
This change enables the SFTP server to reload the user store configuration
(sftp_userstore.json) when a HUP signal is sent to the process, without
requiring a service restart.
Changes:
- Add Reload() method to FileStore to re-read users from disk
- Add Reload() method to SFTPService to handle reload requests
- Register reload hook with grace.OnReload() in sftp command
This allows administrators to add users or change access policies
dynamically by editing the user store file and sending a HUP signal
(e.g., 'systemctl reload seaweedfs' or 'kill -HUP <pid>').
