Zhengchao An 7f19e9a465 Merge commit from fork
docs/testing/security-regressions.md requires every fixed advisory to map to a
named, greppable regression test. Rename the tests added with the fixes to carry
their advisory id so `rg -i ghsa` finds them, and add the four rows to the
advisory -> test map.

Adds the FTPS MKD regression test that was missing. It primes the dummy backend
with a successful create_bucket, so the assertion distinguishes "denied at the
authorization boundary" from "backend refused" — without the queued success an
unconfigured create_bucket fails on its own and the test would pass even with
the authorization check removed. Verified it fails when the check is reverted.

DummyBackend gains a Debug impl (FtpsDriver's trait bounds require it) and a
queue_create_bucket_ok helper.

Records in the CI-execution map why ghsa_g3vq_* runs in the default pass despite
sitting behind the ftps feature: the rustfs crate defaults to ["ftps", "webdav"]
and cargo unifies features across the workspace build, so the test executes
there even though `cargo test -p rustfs-protocols` alone would skip it.

# Security Advisory Regression Tests
Every fixed RustFS GitHub Security Advisory (GHSA) should map to at least one
named, discoverable regression test. The convention is: name the test (or a
helper / doc comment on the exact assertion) after the advisory so that
```bash
rg -i "ghsa|3p3x|r5qv"
```
finds the guard for any advisory, and a future fix of a still-open advisory is
forced to update its pinned test (red -> green).
> This is the lightweight inventory. sec-14 (backlog#1151) formalizes the
> written admission policy in `AGENTS.md`; keep this file as the map.

## Where these run (CI-execution map)
Every security regression must land where CI actually runs it — a named test in
an unexecuted suite is theater. The suites split across three execution paths by
topology:
- **Unit tests** — `ghsa_r5qv_*` (`crates/ecstore`), the GHSA-m77q STS
pinning (`crates/iam`), `ghsa_5354_*` / `ghsa_3ppv_*` / `ghsa_6r96_*`
(`rustfs` lib), `ghsa_v9cp_*` (`crates/policy` crate test), and
`ghsa_g3vq_*` (`crates/protocols`) run automatically in the default CI pass
(`cargo nextest run --profile ci --all --exclude e2e_test`) — no special
wiring. This is the CI-executed regression for the RPC fail-closed (r5qv),
STS-signing (m77q), service-account parent-scope (5354), versioned-read
authorization (3ppv), condition-key injection (6r96), quantified-negation
(v9cp), and FTPS MKD authorization (g3vq) advisories.
`ghsa_g3vq_*` sits behind `rustfs-protocols`' `ftps` feature, which is off by
default for that crate alone. It still runs in the workspace pass because the
`rustfs` crate defaults to `["ftps", "webdav"]` and cargo unifies features
across the build. Running `cargo test -p rustfs-protocols` on its own silently
skips it — use `--features ftps` in that case. The `protocol-features` CI
matrix covers `swift` and `sftp` only, for the same reason: those are not in
any default feature set, so they need explicit jobs.
- **S3-API negative-auth e2e (e2e-smoke, PR-gated)** — the attacker-facing S3
auth-rejection suites run on every PR via the `e2e-smoke` nextest profile
(`.config/nextest.toml`), which each spawns its own server on a random port
and is parallel-safe:
- `negative_sigv4_test` — tampered/wrong-key/skewed header SigV4 (sec-1)
- `presigned_negative_test` — expired/tampered/wrong-key presigned URLs (sec-2)
- `admin_auth_test` — non-admin denial + root-credential lifecycle (sec-4)
A count-floor guard (`scripts/check_security_smoke_count.sh`, floor in
`.config/security-smoke-floor.txt`) runs in the `e2e-tests` CI job and fails if
a rename drops any of these out of the smoke filter (infra-12 mechanism). This
is the sec-5 wiring: those merged suites were dead weight until listed here.
- **Protocol e2e (WebDAV/FTPS constant-time login, GHSA-3p3x)** — lives in the
`e2e_test` protocols suite (`test_protocol_core_suite`), which binds **fixed
ports**, needs the `ftps,webdav` build features, and is `#[serial]`. Those
three properties make it **structurally incompatible** with the random-port,
default-feature, parallel `e2e-smoke` profile: it cannot be a filterset change,
so sec-5 (scoped to a filterset change, global ruling G5) does not wire it.
It runs manually today:
```bash
RUSTFS_BUILD_FEATURES=ftps,webdav cargo test --package e2e_test \
test_protocol_core_suite -- --test-threads=1 --nocapture
```
**Open gap:** GHSA-3p3x's *e2e* layer has no PR-gated CI execution. A protocols
e2e CI lane is a ci-domain concern (a new profile/job, not a filterset change);
it is deliberately out of sec-5's boundary and left as a follow-up.
## Adding a new advisory guard
1. Reproduce the advisory's bypass form as a focused negative test.
2. Name the test (or the helper/assertion) `ghsa_<id>_*`, or attach a
`GHSA-<id>` doc comment with the advisory URL and fix PR.
3. Add a row to the table above.
4. Land it where CI runs it (see the map above): a unit guard in the default CI
pass; an S3-API negative-auth e2e in the `e2e-smoke` filter (add the module to
`.config/nextest.toml` and bump `.config/security-smoke-floor.txt`); a
fixed-port protocol e2e in the protocols suite (still manual — see the open
gap above).
