fix(ip-blocking): the runtime map fast path has never once run
add_ip_to_runtime_map() and remove_ip_from_runtime_map() sent `add map #0 <ip> 1` / `del map #0 <ip>` to /tmp/haproxy-cli and returned True whenever socat exited 0. Neither command has ever worked, on any deployment, for the entire life of the feature -- while logging "Added IP x to runtime map" every single time. Two independent defects: * NO `@1` PREFIX. /tmp/haproxy-cli is HAProxy's MASTER CLI socket; map commands are worker commands. Captured verbatim on whp01: $ echo "add map #0 192.0.2.77 1" | socat stdio /tmp/haproxy-cli Unknown command: 'add', but maybe one of the following ones is a better match: @!<pid> : send a command to the <pid> process ... $ echo $? 0 socat exits 0 on the rejection, so `result.returncode == 0` was true. Same silence PR #7 fixed on the `show table` path. * `#0` IS NOT A VALID MAP ID. Ids are assigned at config-parse time and move on every config regeneration -- `@1 show map` on whp01 reports blocked_ips.map as 37 and trusted_ips.map as 10. There is no id 0. Hardcoding any number is wrong; the map is referenced by FILE PATH, which is what haproxy.cfg itself names in map_ip(/etc/haproxy/blocked_ips.map,0). And a third silence, which is why a response-body check alone is not enough here: `@1 add map #0 <ip> 1` returns an EMPTY body, exit 0, and adds nothing to any map -- while `@1 del map #0 <ip>` and `@1 show map #0` both answer `Unknown map identifier.`. On the add path the reply is byte-for-byte identical to success. Only reading the entry back can tell them apart. IP blocking itself was never broken: update_blocked_ips_map() rewrites /etc/haproxy/blocked_ips.map and the callers reload HAProxy, which re-reads it. That path is untouched and stays authoritative. What was broken is the no-reload fast path, plus every report that it had worked. * haproxy_manager.py: both functions send `@1 add|del map /etc/haproxy/blocked_ips.map <ip> [1]` and READ THE ENTRY BACK with `get map` before returning True. runtime_map_lookup()/runtime_map_keys() are the read-back primitives. `sync_blocked_ips` loses `clear map #0` (which the master socket rejected just as loudly and just as invisibly) and verifies the whole set with one `show map` instead of counting commands that did not visibly complain; it answers 207 + `runtime_map_synced: false` when the runtime map does not match the database. * haproxy_cli() grows `expect_empty=True` for MUTATING commands: HAProxy answers those with nothing on success, so an empty body is the success and ANY non-empty body is a rejection. That is stricter than the marker list on purpose -- markers only recognise rejections someone has already seen, and it catches `'add map' expects three parameters ...`, which matches nothing. HaproxyCliError carries `.responses` so `del map` answering `Key not found.` (the requested end state) is told apart from a real failure without regex. * The four callers capture the boolean instead of discarding it and report `runtime_map_updated` / `runtime_map_failures` in the API response and the operation log. A runtime failure degrades to "enforced on the reload that already happens two lines later" -- never to an unblocked IP, never to a 500. * scripts/test-runtime-map-contract.py (offline, 26 tests) asserts the bytes on the wire (`@1` first, map by path, value `1`), classifies every captured response, and scans the repo's Python string literals and shell/template code lines for `#<id>` map references -- comments may describe the old form, code may not use it. Verified to fail on each defect reintroduced separately: no `@1` (3 failures), `#0` (4), no read-back (2), trust-the- reply (1). * The `#0` form is also corrected in IP_BLOCKING_API.md, MIGRATION_GUIDE.md and the comment in templates/hap_listener.tpl -- where every copy of it additionally omitted the `1`, which `-m int gt 0` needs to match. The only template change is a comment; `haproxy -c` on the live rendered config with it applied is clean (HAProxy 3.0.11, warnings unchanged). Verified on whp01 against the running container (docker cp + SIGHUP, no recreate). Before: both functions returned True and logged success while `@1 get map` answered `found=no` and entry_cnt stayed at 263. After: the fixed add lands with value "1" and the remove takes it out again; the old command form is now classified as a failure; a `#0` map reference returns False via the read-back. End to end through the API, `runtime_map_updated: true`, and /api/blocked-ips/sync -- which used to be a no-op reporting a full sync -- reports 264/264 verified present. The runtime path was isolated from the reload that normally follows it: with NO map-file write and NO reload (same haproxy worker pid throughout), adding 100.123.171.78 (whp01's own netbird overlay address -- not a customer IP, not in the is_local ranges) to the runtime map alone flipped a live site from HTTP 200 to 403, and removing it flipped it back to 200. That is the fast path working for the first time. All test IPs were removed afterwards: 0 rows in blocked_ips, 0 lines in the map file, entry_cnt back to 263. Six customer sites, the panel /health and `haproxy -c` are byte-identical to the baseline taken before the change. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

fix(security-stats): stop reporting counters the stick tables never stored
/api/security/stats and scripts/show-tarpit-ips.sh reported "Scan Count",
"offense count" and BLOCKED/TARPITTED status parsed from gpc0/gpc1. No stick
table in this repo has ever stored a general-purpose counter -- the `web` table
stores conn_cur, conn_rate(10s), http_req_rate(10s), http_err_rate(30s), and
the two brute-force tables store http_req_rate(60s). Every one of those figures
was fabricated, and an operator was making decisions on them.
Three independent silences kept it alive:
* `int(parts[3])` on a positional split hit `exp=368842`, raised ValueError,
and the loop `continue`d -- so the endpoint always answered
`active_threats: 0` with an empty list. Live on whp01 it also reported
parts[0], the `0x...:` allocation pointer, as the source IP.
* The command was sent to /tmp/haproxy-cli WITHOUT the `@1` worker prefix.
That is the MASTER CLI socket, which answers "Unknown command: 'show' ..."
-- and socat still exits 0, so the `returncode != 0` guard never fired.
`total_tracked_ips` was the line count of that help text (8) while the real
table held 388 entries.
* The shell consumers wrote `gpc0=${gpc0:-0}`, rendering a field that does
not exist as a confident zero.
Report what the tables actually store, rather than adding gpc counters to make
the old semantics real. Adding them would mean editing hap_listener.tpl -- the
one change here with a silent-total-outage failure mode -- to rebuild
enforcement history that the edge access log (shipped 2026.08.8, on the host at
/var/log/haproxy.log) already records per request, with status codes,
termination states and request references the stick table could never hold.
* haproxy_manager.py: STICK_TABLE_FIELD_CONTRACT names what each table
stores. haproxy_cli() sends worker commands with `@1`, falls back to the
bare form for a plain stats socket, and inspects the RESPONSE BODY because
socat's exit status is worthless here. parse_stick_table_entry() reads
name=value / name(window_ms)=value pairs by NAME, never by position.
read_stick_table() RAISES -- naming the field -- when a row is missing a
contract field, instead of defaulting it to 0.
* /api/security/stats returns the four real counters with their windows, the
true `used:` count, and no invented threat_level/blocked/offense_count.
Fewer numbers, all of them real.
* scripts/show-edge-ip-rates.sh replaces the fabricated report; the four
expected fields are declared once as EXPECTED_FIELDS and drive the parser.
show-tarpit-ips.sh becomes a shim that explains why its numbers are gone
and points at where tarpit events actually live.
* monitor-attacks.sh loses fourteen fabricated "threat" categories and a
composite threat score, all permanently zero; its access-log section now
says the log is on the host instead of silently printing nothing.
* haproxy_tarpit_config.txt -- the never-shipped design sketch these counters
were copied from -- gets a NOT IMPLEMENTED banner.
* scripts/test-stick-table-contract.py (offline, 21 tests) holds the
templates' `store` clauses, STICK_TABLE_FIELD_CONTRACT and every consumer
to each other, and asserts each loud-failure path against the real captured
responses. Template and consumers can no longer drift apart quietly.
No template is touched, so haproxy.cfg is unchanged.
Verified on whp01: total_tracked_ips now tracks `used:` exactly (511 vs the
table's 511, was 8 vs 388), and per-IP values match `show table web key <ip>`
field for field. haproxy PIDs unmoved, `haproxy -c` warnings unchanged, five
customer sites HTTP 200.

fix(haproxy): silence the ACL pattern warning on wp_admin_asset
HAProxy warns on any pattern whose first character is "(", because it
cannot distinguish an intended regex from a fetch-argument list with a
stray space:
parsing acl 'wp_admin_asset' : matching 'path_reg' for pattern
'(^|/)wp-admin/...' is likely a mistake and probably not what you want.
"--" is HAProxy's documented end-of-flags marker and is the remedy the
warning itself names. Cosmetic to matching, but not to operations: left
unsilenced it fires on every config load and every reload on every host,
which trains operators to skim past warnings and gives a real one
somewhere to hide.
Matching semantics are unchanged, verified rather than assumed. Both
forms were run side by side as two frontends under real HAProxy
3.0.11-1+deb13u3 and gave identical verdicts on all 8 vectors:
/wp-admin/css/login.min.css MATCH / MATCH
/wp-admin/js/user-profile.min.js MATCH / MATCH
/wp-admin/images/x.png MATCH / MATCH
/wp-admin/css/sub/deep.css MATCH / MATCH
/blog/wp-admin/css/a.css MATCH / MATCH
/wp-admin/css/x.php NOMATCH / NOMATCH
/wp-admin/plugins.php NOMATCH / NOMATCH
/some--path/file.css NOMATCH / NOMATCH
The last vector is the one that matters: it proves HAProxy consumed "--"
as end-of-flags rather than adopting it as the pattern. Had it done the
latter, the ACL would have matched paths containing "--" and stopped
matching css/js -- gating every login page's own stylesheets while the
page itself still returned 200.
wp_admin_path needs no "--" only because its "-i" flag already occupies
the flag slot; it is not otherwise special.
Adds a regression test asserting both the "--" and the pattern it
guards, so this cannot pass by the pattern having been changed. Verified
to fail when the "--" is removed.

ci: gate the build on a real haproxy -c of the rendered config
A config change can render perfectly, pass every unit test in scripts/, and
still be rejected outright by HAProxy. That happened on 2026-08-14: an inline
`regsub((^|/)wp-admin/.*,\1wp-login.php)` in a redirect location produced
"invalid arg 2 in converter 'regsub'". Thirteen tests were green. It was only
caught because someone built an image by hand and ran `haproxy -c`.
Nothing between commit and production would have stopped it. The unit suites
assert on the TEXT of the rendered config with regexes, which says what the
template emits, never whether HAProxy accepts it. test-config-rollback.py's
"validation" stubs the haproxy binary with a shell script that rejects one
sentinel token and has never parsed a line of real syntax. And
.gitea/workflows/build-push.yaml is checkout -> build -> push, with no tests
at all.
The production consequence is not a broken deploy, it is a silent outage:
init.py refuses to start HAProxy on an invalid config while the container
still comes up, so ports 80/443 are unbound, every site on the host is down,
and /health keeps answering 200.
scripts/validate-rendered-config.py renders the config through the real
generate_config() - every template, real order, both conditional branches
({%- if suspension_enabled %} and {%- if coraza_spoe_backend %}) rendered on
in one scenario and off in the other - creates the stub files the config
loads via `-f` (a missing one is a FATAL haproxy error and would be a false
failure), then runs `haproxy -c` and gates on its EXIT CODE. Warnings are
expected on a clean config ("Can't load stats file", path_reg advisories) and
are not failures; on a real failure the full haproxy output plus the offending
config lines go to the build log.
It runs as a Dockerfile RUN rather than a CI step so it cannot be skipped, so
it protects local builds too, and - the reason that matters most - so it
validates against the EXACT haproxy binary in the image being built. The
Dockerfile installs haproxy unpinned, so that binary moves between builds;
this turns "the new haproxy rejects our config" from a silent production risk
into a build failure. Gating in CI instead would also have meant splitting
build-push-action's single build-and-push step.
The six existing unit suites run in the same step. They had never run
anywhere automated either, and they cost about five seconds.
Verified both ways: the clean build passes and the gate's output appears in
the log; reintroducing the known-bad regsub into a copy of the template fails
the build with HAProxy's own "invalid arg 2 in converter 'regsub' : missing
arguments (got 1/2)".

test(haproxy): harden wp-admin gate suite against comment-collision, fix two false doc claims
Adversarial mutation audit found the wp-admin gate test suite (26 tests, all
green) did not actually test the feature: 14 of 26 assertions ran bare
str.index/assertIn/re.search over the full rendered config, so they matched
this file's own explanatory comment blocks (which quote ACL names and whole
rules) just as happily as the real rule. Deleting the entire redirect rule,
or `acl wp_admin_allowed`, or all five normalizers, left the old suite at
26/26 PASS. rule_lines() also only stripped whole-comment lines, so a
trailing " # decoy" comment on a surviving line could impersonate a deleted
one, and one ordering test used bare cfg.index() which still "finds" a
normalize-uri directive that has been fully commented out (the substring
survives after the '#').
Rewrites every rule-presence/content/ordering assertion to go through
rule_lines()/rule_positions(), now truncating each line at the first ' #'
before matching, and adds require_rule()/require_position() guards so a
missing rule raises a named AssertionError instead of IndexError or
"substring not found". Adds dedicated declared-ACL tests for wp_admin_path,
wp_admin_asset, wp_admin_allowed and wp_gate_exempt so each has its own
direct, comment-safe check. 29 tests now (was 26).
Proved via a mutation harness (copy templates to a scratch dir, mutate the
copy, run the suite via HAPROXY_MANAGER_DIR, restore): commenting out the
redirect rule, either deny rule, any of the four wp_admin_* ACLs, any one of
the five normalize-uri lines, or expose-experimental-directives now reddens
the suite -- 13/13 required mutations caught, plus the exact trailing-comment
decoy and "all five normalizers commented at once" cases from the audit.
Also corrects two doc claims the audit found factually wrong:
- hap_listener.tpl: normalize-uri's percent-to-uppercase and
percent-decode-unreserved rewrite the WHOLE request-target, not just the
path -- measured examples included, and the query-sort-by-name rejection
reasoning ("every rule matches path") was a non-sequitur given that. Real
reason to leave it off: reordering would break signed/cached URLs. Fleet
checked: no .NET backends, no URL-in-path proxies, no known victim today.
- hap_header.tpl: dropping expose-experimental-directives does not
crash-loop the container. do_initial_setup() swallows the `haproxy -c`
failure and start_haproxy() returns without raising, so start-up.sh execs
gunicorn as PID 1 anyway -- a silent total outage (ports 80/443 unbound,
every site down) that ensure_haproxy.py retries forever without
escalating, while GET /health keeps answering 200.
No HAProxy rule, ACL, or normalizer changed -- comments and tests only.
Verified: all 5 required suites green, and `haproxy -c` against the real
haproxy 3.0.11 (Debian package) still exits 0 with only the same pre-existing
warnings as before (wp_admin_asset path_reg advisory, stats file).

fix(haproxy): normalise the URI before matching, closing five gate bypasses
The wp-admin edge gate matched the RAW request path while the backend
normalised and decoded it before resolving a file. Every gap between those
two behaviours was a bypass, and five had already been patched individually:
//wp-admin/plugins.php fell through ungated
/wp-admin/css/../plugins.php took the static-asset bypass
/wp-admin/js/%2e%2e/plugins.php same, percent-encoded
/wp%2Dadmin/plugins.php matched no wp-admin ACL at all
/wp-admin%2Fplugins.php encoded separator, served by OLS
Stop patching vectors and normalise once, first, so every path-based rule in
the frontend sees the same string the backend will resolve:
percent-to-uppercase
percent-decode-unreserved
path-merge-slashes
path-strip-dot
path-strip-dotdot full
Order was determined empirically against real haproxy 3.0.11, not from the
docs: the decoders MUST precede the path walkers, or %2e%2e is decoded to ..
only after path-strip-dotdot has already run and the traversal survives. Plain
path-strip-dotdot also leaves /../../ untouched -- "full" is required.
query-sort-by-name is deliberately not enabled; it reorders query parameters
and would break anything signing or caching on the exact query string.
normalize-uri is experimental in 3.0, so global gains
expose-experimental-directives -- without it haproxy does not start at all.
The two must be added and removed together.
%2F cannot be closed by normalisation ("/" is reserved, so decoding it is
correctly refused), so it gets its own deny, scoped to paths mentioning
wp-admin so non-WordPress apps that pass encoded slashes in path parameters
keep working. Deny rather than redirect: regsub finds no "/wp-admin/" in
"/wp-admin%2F...", so a redirect would point at the request's own URL.
Gate changes:
* wp_admin_safe_path KEPT -- merge-slashes kills its "//" vector but not
"/\", which no normalizer touches. Its failure mode (unsafe path is not
redirected, therefore falls through UNGATED -- the original C1) is now
closed by an explicit deny instead of being left implicit.
* wp_admin_asset now excludes .php, so the asset bypass cannot cover a PHP
entrypoint even if an encoding trick ever survives normalisation.
* wp_admin_path is case-insensitive, paired with a matching regsub flag --
adding either alone is an infinite redirect loop.
Verified behaviourally against real haproxy 3.0.11 with raw sockets (curl
normalises client-side and hides these), run twice: once against the rendered
templates and once against the haproxy.cfg generated by a real, healthy
container. 12/12 gated, 19/19 passed through, 7/7 with no off-site Location,
plus ~30 adversarial vectors. haproxy -c exits 0 and the container reaches
healthy. Blast radius measured on a 40-URL production-shaped corpus: 4
rewritten, all RFC-equivalent (%7E->~, /./ , //); query strings and all
non-unreserved escapes byte-identical.

fix(haproxy): close open redirect in wp-admin edge gate
The redirect target is built by regsub-rewriting `path`, which only replaces the matched "/wp-admin/.*" substring -- anything before it survives untouched. Three request forms turn that survival into an off-site Location header: a protocol-relative "//evil/wp-admin/x.php", a browser-normalized "/\evil/wp-admin/x.php", and an RFC 7230 absolute-form request target. Without this gate those paths simply 404 against WordPress; the gate itself is what would have exposed a fleet-wide phishing primitive. Adds a positive wp_admin_safe_path ACL (path_reg ^/[^/\\]) requiring a well-formed absolute path, required alongside the existing conditions on the redirect rule. A path that fails it is simply not redirected and falls through to the backend -- pre-gate behavior, so no regression. set-var is left unguarded since it only computes a variable; the redirect is what emits the header, so guarding it is sufficient. Verified against real HAProxy 3.0.11: the naive two-backslash form fails to compile (config-line word parsing collapses "\\" to one backslash before PCRE sees it, leaving an unterminated class); four backslashes are required in the template so PCRE receives the intended single-backslash class member. Confirmed live, via a differential test against the pre-fix rule, that both the // and /\ vectors previously produced off-site Location headers and now do not, while normal root and subdirectory-install redirects are unaffected.

feat(haproxy): rate-limit POST /xmlrpc.php floods per client IP
Mirrors the existing wp-login.php brute-force protection. Generic frontend limits trigger at 300-500 req/s (sized for media-heavy pageloads), but observed xmlrpc floods run at just a few req/s for hours -- well under that ceiling while still pinning PHP-FPM workers and driving 503s fleet-wide (1,011 in one day on a single site). Adds a dedicated stick-table (xmlrpc_bruteforce, sc2) rather than reusing wp_bruteforce: sharing a counter would let wp-login and xmlrpc traffic from the same IP inflate each other's rate. Tarpits at 60 req/min/IP (double wp-login's 30, since xmlrpc is machine-to-machine and legitimately bursts -- Jetpack sync, mobile app, remote publishing). Honors the same whitelist as every other rule in the file and does not block the endpoint outright. Only safe to key on var(txn.real_ip) because of the trusted-proxy header gate shipped earlier today (2026.08.3) -- before that, per-IP tracking was trivially evaded via a spoofed X-Forwarded-For. Adds scripts/test-xmlrpc-rate-limit.py (stdlib unittest, no pytest in this repo) pinning the tracking rule, the tarpit threshold, the path_end ACL, and the whitelist exclusions. Existing trusted-proxy-gate, config-rollback, and cert-write-safety regression suites all still pass unmodified. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> |

fix(haproxy): stop the trusted-proxy volume from shadowing Cloudflare/proxy lists
/etc/haproxy is a named volume in deployed containers, so the baked-in
cloudflare_ips.list and trusted_proxies.list COPYed there in the prior
task never actually reached hosts with a pre-existing volume -- the
start-up.sh guard then found them "missing" and created them empty.
With both lists empty, the from_trusted_proxy ACL in hap_listener.tpl
matched nothing, so CF-Connecting-IP / X-Real-IP / X-Forwarded-For got
stripped from every peer, including Cloudflare's own edge. Confirmed
live: image shipped 34/13 lines, running container had 0/0.
Fix: stage both files under /haproxy/defaults (outside the volume) and
apply their ownership rule in start-up.sh instead of a blind
"create if missing":
- cloudflare_ips.list is shipped data -- always refresh it from the
baked default so Cloudflare range updates reach existing hosts.
- trusted_proxies.list is operator data -- seed it from the baked
default only when missing, and never overwrite what an operator
added on the server.
Both branches fall back to creating an empty file if the baked default
is somehow absent, since a missing "-f" target is a fatal HAProxy
config error.
Verified against a volume pre-populated to shadow the image (mimicking
a real host): cloudflare_ips.list repopulates with all 15 IPv4 + 7
IPv6 ranges even after being truncated and restarted; a distinctive
operator entry appended to trusted_proxies.list survives a restart
untouched; haproxy -c still validates cleanly.
Release-worthy fix for a defect from the just-released 2026.08.2 build.

fix(certs): stop the test suite bricking the container; make the pairing check real
Gate findings on fix/cert-write-safety. One blocker, one latent truncation
path, a false premise in a load-bearing comment, and a set of tests that were
passing without testing anything.
THE BLOCKER - scripts/test-cert-scripts.py bricked the production container
------------------------------------------------------------------------
The openssl-availability tests build a stripped PATH out of SYMLINKS to real
system binaries (cat, grep, mktemp, mv, cp, rm, mkdir, basename, dirname, find,
date, chmod). _cleanup_tmp() then walked the temp tree calling os.chmod(p,
0o600) - and os.chmod FOLLOWS SYMLINKS. Run once as root in the real image,
which is where this file ships (COPY scripts /haproxy/scripts) and where an
operator would most plausibly run it after deploying a cert fix, it stripped
the exec bit off twelve core binaries INCLUDING chmod itself, so it could not
be undone from inside the container:
/haproxy/scripts/cert-publish-lib.sh: line 109: /usr/bin/grep: Permission denied
bash: /usr/bin/chmod: Permission denied
Certificate publishing stayed dead until the container was recreated. It was
invisible on a workstation because an unprivileged chmod of a root-owned file
fails EPERM straight into `except OSError: pass` - which is also why the
advertised "32 tests pass" was only ever true off-container. In the image the
shipped file measured FAILED (failures=22, skipped=1). Cleanup now skips
symlinks; the suites are green in the image and the binaries survive.
S1 - the shell half had no same-filesystem guard
------------------------------------------------
The header claimed a cross-device mv would "FAIL LOUDLY and leave the live pem
alone". GNU mv does the opposite: across filesystems it copies, so it opens and
truncates the DESTINATION and only then discovers it cannot finish - measured
as a 204800-byte partial live.pem, sentinel gone, before mv reported ENOSPC.
cert_publish() now compares stat -Lc %d of the staging and certs dirs before
writing anything, mirroring the st_dev check the Python half already had, and
the comment says what mv actually does. Latent today (both dirs share a device
on all five hosts) but both are env-overridable.
openssl is present - correct the premise, make the check mandatory
------------------------------------------------------------------
Both halves justified a fail-open with "the image does not necessarily install
the openssl CLI". It does: openssl 3.5.6 in the running container, pulled in by
ca-certificates which certbot needs, and generate_self_signed_cert() already
shells to `openssl req` with check=True during setup. The 'unavailable' branch
never fired, so the pairing check has always run - and that, not the stated
reasoning, is what made the fail-open harmless. Structural validation alone is
weak: a bundle of EMPTY pem blocks passes every structural rule and is caught
only by openssl. The check is now mandatory in both halves and a missing binary
is a loud refusal. No `cryptography` fallback: the app runs on
/usr/local/bin/python3 (3.12) where it is not importable - it belongs to
Debian's /usr/bin/python3 - and reaching for that would be a second unverified
premise.
Smaller items
-------------
* cert_bundle_valid() read the file six times; a concurrent swap between two of
them made openssl x509 and openssl pkey judge different files and log a bogus
"private key does not match the certificate" into the monitored error log. It
now reads one snapshot and feeds openssl from it on stdin.
* except OSError -> except (OSError, UnicodeDecodeError): a BINARY-corrupt live
pem made backup_existing_pem() raise out of publish_pem_bundle() entirely, so
the republish that would have healed the host was the one thing that could
not run. The shell half recovers fine.
* stat -c %a on a symlinked live pem reports the LINK's 0777 and produced a
world-writable private key in the crt directory; now stat -Lc.
* The staging reaper's '*.??????' glob matched mktemp names but not the Python
side's '<name>.<random>.tmp', so those leaked forever. Matches both now.
* renew-certificates.sh and sync-certificates.sh exited 0 even when every
domain failed to publish, so "0 updated, 12 failed" looked identical to a
clean run to cron, to host-renew-certificates.sh (which branches on it) and
to monitoring - a host could silently stop publishing renewals until the
certificates expired. They now exit 1 if any domain failed, still after
publishing the ones that worked.
Test-quality
------------
Four TestCertPublishLibrary tests passed with cert-publish-lib.sh DELETED -
they asserted only rc != 0, and `command not found` is 127. All four now assert
the rejection REASON via assert_rejected(), and setUp() fails if the library is
missing. test_missing_openssl_still_rejects... is replaced by
test_empty_pem_blocks_are_rejected, which pins the case that makes the pairing
check necessary.
Also: the staging-containment test used startswith(certs + os.sep), so
cert_staging_dir() returning the crt directory ITSELF - the exact hazard -
still passed; test_successful_renewal_still_publishes built its "renewed" cert
with a no-op .replace() and could not tell a renewal that published nothing;
test_no_temp_file_survives_a_failed_publish failed before the staging dir
existed and asserted [] == []; FIX_ONLY was skipUnless(hasattr(hm,
'publish_pem_bundle')), so renaming that function turned 10 of 17 tests into
skips while the run still printed OK. Each is fixed and each fix is
mutation-proved: the mutation that the old assertion waved through now fails.
File mode is pinned in both suites (it was pinned nowhere), and the rename
failure is injected with a stub mv instead of chmod 0500, which root ignored -
so that test no longer skips itself precisely where it matters.
Verification
------------
IN THE BUILT IMAGE, as root (the acceptance bar):
scripts/test-cert-scripts.py 38 tests, OK, 0 skipped
scripts/test-cert-write-safety.py 22 tests, OK, 0 skipped
scripts/test-config-rollback.py 17 tests, OK (neighbour, unchanged)
Workstation: 38/38 OK for the shell suite; the Python suite needs flask.
Against the pre-fix tree (main): shell 38 failures; python failures=4, errors=1,
skipped=15 - the FIX_ONLY skips are the 14 fix-only tests plus the API guard.
The old python suite against the pre-fix tree measures skipped=10, confirming
the gate's count.
32 mutation checks, all behaving as intended: every fix breaks a test when
reverted, and every rewritten test fails under the mutation its predecessor
passed. py_compile clean, bash -n clean, shellcheck clean, no new pyflakes
warnings (same 4 pre-existing).

fix(certs): never truncate a live PEM; validate before publishing
Every path that refreshed a combined certificate did
with open(combined_path, 'w') as combined: # TRUNCATES
subprocess.run(['cat', cert, key], stdout=combined) # rc ignored
where combined_path is the bundle HAProxy is currently serving. The live file
was emptied before any source material had been read and the cat status was
never checked, so an unreadable source, a zero-length privkey, a full disk or a
killed container left a truncated or key-less PEM in place. HAProxy loads
/etc/haproxy/certs as a directory, so one unusable file there fails the whole
ssl bind - HTTPS down for every site on the host, and unlike a bad haproxy.cfg
it is not recoverable by config rollback.
The bundle endpoint compounded it: superseded .pem files were unlinked and
their lineages `certbot delete`d before anything had checked the replacement,
destroying both copies of a working certificate. Recovery there means fresh,
rate-limited ACME orders.
Bundles are now assembled in a staging directory beside the crt directory (never
inside it - HAProxy would try to load a temp file), validated there, and swapped
in with os.replace(). Validation is mandatory structural checks in pure Python
plus a best-effort openssl key/leaf pairing check; a missing openssl warns
loudly and does not silently pass. The previous bundle is copied to
/etc/haproxy/cert-backups first. Superseded certs are moved aside rather than
deleted, and `certbot delete` runs only after HAProxy has reloaded onto the
replacement. The same guarantees are implemented for the cron/renewal shell
path in scripts/cert-publish-lib.sh, which also gates the reload on `haproxy -c`.
Reuses write_config_atomically() from the config-rollback fix (extended with
staging_dir/validate) rather than adding a second atomic writer.
Also heals a zero-byte QUIC cluster-secret file, which previously made
get_or_create_cluster_secret() return '' forever.
Tests: scripts/test-cert-write-safety.py (17) and scripts/test-cert-scripts.py
(32) in the existing stdlib-unittest, stub-binary convention. Both bug classes
reproduce against the pre-fix tree via HAPROXY_MANAGER_DIR.

fix(config): take the rollback backup BEFORE writing the new config
generate_config() wrote /etc/haproxy/haproxy.cfg and only then called
reload_haproxy_safely(), which called create_backup(). The "backup" was
therefore a copy of the config that had just been written, so on a validation
failure restore_backup() restored the identical broken bytes: the advertised
rollback was a no-op and a fatal haproxy.cfg stayed on disk, where
start_haproxy() refuses to launch. Same shape as the June 2026 incident where
a missing template produced a fatal config and took an edge down.
Reproduced end to end before the fix (invalid config generated -> "Backups
created successfully" -> "Backups restored successfully" -> haproxy.cfg on
disk still invalid, `haproxy -c` rc=1).
Changes:
* create_backup() is now called by generate_config() BEFORE the first write,
which also covers blocked_ips.map (rewritten early in generate_config) and
coraza-spoe.cfg - both previously written before the backup and, for the
SPOE file, never backed up at all even though `haproxy -c` parses it.
* create_backup() refuses to promote a config HAProxy already rejects, so a
broken file on disk cannot overwrite a known-good backup ("rollback" must
not mean "restore a different broken config"). It returns (ok, status) so
the caller knows whether a rollback target exists.
* promote_current_config_to_backup() records the config as known-good only
after it has validated AND loaded, so a box whose first generation succeeded
has a rollback target immediately, and a config that never loaded is never
promoted.
* restore_backup() returns (restored, message) and distinguishes "no backup
available" from "restored". Every caller now surfaces the difference; a
failed rollback is logged CRITICAL and reported as ROLLBACK FAILED in the
API error message instead of silently looking like a successful recovery.
* reload_haproxy_safely(backup_status=...) no longer takes its own backup - it
runs after the write, where a backup is meaningless. Called without a status
it logs the contract violation rather than overwriting a good backup.
* validate_config_file() separates "config is invalid" from "validator could
not run" so a missing haproxy binary is not read as a bad config.
* Config writes are atomic (temp file + fsync + os.replace, mode preserved);
a truncated haproxy.cfg is as fatal as an invalid one. Removes the dead
temp_config_path variable whose comment claimed this already happened.
* Fast path: if the live config set is already byte-identical to the backup
(the normal case after a successful reload), skip the re-validation and the
copy, so this adds no `haproxy -c` latency to customer-facing API calls.
Tests: scripts/test-config-rollback.py - 17 self-contained stdlib-unittest
tests, no new dependencies (the repo has no Python test framework; the
existing scripts/test-*.sh are curl integration scripts). A stub `haproxy`
binary stands in for the validator. 12 of the 17 fail against the previous
code; every assertion was mutation-proven (9 mutations, each reddening only
the tests that cover it).
No template, QUIC or HTTP/3 changes.

fix(api): bound all subprocess calls + run 2 workers to prevent API stall
HAProxy Manager Build and Push / Build-and-Push (push) Successful in 1m9s
The management API wedged on whp01 2026-07-07: every panel call to the manager (config regenerate during a WHP site update, SSL, even /health) timed out at 30s while customer sites stayed up. Root cause: all four gunicorn gthread worker threads were permanently blocked in socket reads inside untimed subprocess.run() calls (certbot ACME / socat reloads). A stalled external command holds its worker thread forever; gunicorn --timeout can't rescue it (gthread only kills a worker whose main thread stops heart-beating, and ours kept polling). Stalled calls accumulated until the 4-thread pool was exhausted and the whole API went dark. - Wrap subprocess.run with a default timeout (HAPROXY_MGR_SUBPROCESS_TIMEOUT, 180s) so every external command is bounded and releases its thread on expiry via the existing per-endpoint try/except. Bounding by default covers all ~30 call sites and any future one. - certbot renew keeps an explicit 900s timeout (walks every lineage). - API_WORKERS default 1 -> 2: a single worker made a thread-pool wedge a total outage; a second worker keeps the API answering while one recycles.

fix(supervisor): restart haproxy in-place if it dies while container lives
HAProxy Manager Build and Push / Build-and-Push (push) Successful in 1m11s
haproxy runs as a background child of PID 1 (gunicorn) with nothing watching it after init. If the haproxy master dies mid-life (observed 2026-07-01 on whp01: SIGABRT -> exit 134, reaped by gunicorn and logged as "Worker (pid:22) exited"), the container stays "up", Docker's --restart never fires, and haproxy is down until the external host watchdog full-restarts the whole container minutes later (dropping every connection). Add an in-container supervisor loop in start-up.sh (Phase 1.5) that runs scripts/ensure_haproxy.py every HAPROXY_SUPERVISOR_INTERVAL (default 15s). ensure_haproxy.py calls the existing, idempotent start_haproxy() only when haproxy isn't running (psutil guard), reviving it in place within one interval with no container restart. Same entrypoint-supervision pattern shipped for cac-litespeed. Validated locally: killing haproxy -> revived with new PIDs in ~one interval, container stayed healthy, no spurious restarts while healthy.

swap werkzeug dev server for gunicorn + accept all HTTP methods on default/blocked pages
Two related fixes for the issues the AI Monitor surfaced on whp01 on 2026-05-12 (haproxy-manager going "healthy but stalled" after long uptime, and noise from POST /blocked-ip returning 405): 1. Production WSGI server. The Flask app was running on werkzeug's built-in dev server (the one that prints "WARNING: This is a development server" on every startup). werkzeug is single-threaded and accumulates worker state over long uptimes; after ~24h on whp01 the health endpoint stops responding while the container still reports "healthy" because Docker's HEALTHCHECK uses an HTTP probe from inside the same werkzeug process that's stalled. Replace with gunicorn (gthread worker class, --max-requests=1000 with jitter so workers recycle periodically). Two gunicorn instances, one per Flask app — port 8000 for the management API, port 8080 for the default/blocked-ip page server. Both lift their app objects from the haproxy_manager module so gunicorn can import them. Required structural change: default_app was created INSIDE the __name__ == '__main__' block at module bottom, where gunicorn could never reach it. Moved to module level. The __main__ block now stays only for `python haproxy_manager.py` local-dev workflow. Container init (init_db, certbot register, generate_config, start_haproxy) extracted into a do_initial_setup() function called from a new scripts/init.py. start-up.sh runs init.py to completion before either gunicorn binds, which keeps HAProxy startup off the WSGI workers' fork paths (no race between workers all trying to start_haproxy() at once). 2. /blocked-ip and / accept ALL methods. HAProxy proxies blocked-IP traffic to default_app preserving the original verb, so a blocked POST request used to hit Flask's GET-only route and get a 405 + the AI Monitor flagged the noise. Adding the full method list lets the 403 page render regardless of verb. Gunicorn settings tunable via env (workers, timeout, max-requests). API gets --timeout 120 because ACME cert issuance can be slow; the default page server stays on the gunicorn default 30s. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

Don't abort cert renewal when a single domain fails
The renewal script was exiting immediately when certbot returned a non-zero exit code, which happens when ANY cert fails to renew.

Fix certificate renewal to properly update HAProxy combined certificate files

After certbot renews certificates, the separate fullchain.pem and privkey.pem files must be combined into a single .pem file for HAProxy. The renewal script was missing this critical step, causing HAProxy to continue using old certificates.

Increased thresholds significantly: - Initial trigger: 10 → 25 errors - Medium level: 20 → 40 errors - High level: 35 → 60 errors - Critical level: 50 → 100 errors 2. Only count actual scan attempts as errors: - Script files: .php, .asp, .jsp, .cgi, .pl, .py, .rb, .sh - Admin paths: /wp-admin, /phpmyadmin, /adminer - Config files: .env, .git, .htaccess, .ini, .yml - Backup files: .backup, .bak, .sql, .dump - Known vulnerable paths: /cgi-bin, /fckeditor 3. Explicitly exclude legitimate assets from counting: - Images: .jpg, .png, .gif, .svg, .webp - Fonts: .woff, .woff2, .ttf, .eot, .otf - Static: .css, .js, .map, .pdf - Common paths: /static/, /assets/, /fonts/, /images/ 4. Still count all 401/403 errors (auth failures are suspicious) This prevents missing fonts, images, CSS files from triggering blocks while still catching actual vulnerability scanners. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> |

Add safeguards to prevent false positive blocking
HAProxy Manager Build and Push / Build-and-Push (push) Successful in 52s
- Handle common missing files (favicon.ico, robots.txt) without counting as errors - Return 404 directly from frontend for these files (bypasses backend counting) - Add clear-ip.sh script to remove specific IPs from stick-table - Keep trusted networks whitelist for local/private IPs This prevents legitimate users from being blocked due to browser requests for common files that don't exist. Usage: ./scripts/clear-ip.sh <IP_ADDRESS> 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com> |
