Fix rpm signing: hand the built packages back to the runner user

The rpm build runs in a container as root, so the packages arrived in the
workspace owned by root. Renaming them still worked, since that only needs
write permission on the directory, but rpm --addsign rewrites the file in
place and failed:

    error: 3proxy-0.9.9.0.el9.x86_64.rpm: open failed: Permission denied

Restore the invoking user's ownership before leaving the container, falling
back to a mode change where the container cannot chown, as under a rootless
container runtime.

CHANGELOG

@@ -1,13 +1,18 @@
-3proxy-1.0.0 Released August, 22 2026
+3proxy-0.9.9 Released August, 20 2026
 
-No changes in 3proxy code, this release only changes how packages are built, signed and published.
-
-! Fix: TLS, PCRE2 and PAM support was silently left out when 3proxy was built on a system whose /bin/sh is not dash, which is every RPM based distribution and macOS; the library checks built their test program with echo and escape sequences, which only dash expands, so every check failed and the features were dropped without a diagnostic
-! Fix: rpm packages were built on Ubuntu and required glibc 2.38, libssl.so.3 and libpcre2-8, which no RPM based distribution provides, so they could not be installed anywhere; they are built against AlmaLinux 8, 9 and 10 now and carry an el8, el9 or el10 tag, covering RHEL, AlmaLinux, Rocky and CentOS Stream of the same version
-! Fix: the rpm package depended on its own interpreter, /bin/3proxy, taken from the first line of the installed configuration file, and could not be installed on el9 or el10 because rpm resolves that dependency to /usr/bin/3proxy
-! Fix: deb packages required glibc 2.38 and libssl3t64 and installed on Ubuntu 24.04 and newer only; they are built against Ubuntu 22.04 now and install on Ubuntu 22.04 and later as well as Debian 12 and later
-+ Signed apt and dnf repositories are published at https://3proxy.org/repo/ in two channels: current, built from the master branch, and lts, built from the 0.9 branch; packages and repository metadata are both signed
-+ Release binaries are published with SHA256 checksums, an OpenPGP signature and a GitHub build provenance attestation; docker images are signed and attested as well
-+ The release signing key is an RSA-4096 key published as 3proxy-release-key.asc in the repository; rpm 4.14 and earlier can not import an Ed25519 key at all, which would leave RHEL 8 and its derivatives unable to verify anything
-+ Packages are reproducible: rebuilding a release produces byte identical deb and rpm files, every timestamp is derived from the build date recorded for the release
-- 32-bit ARM (armhf) is published as a deb package only, Enterprise Linux has no 32-bit ARM build
+! Fix: DNS replies are validated now: a reply from an address other than the nameserver the query was sent to, and a reply with a question section not matching the query, are dropped; both were accepted before
+! Fix: socket leak with SOCKSv5 UDP ASSOCIATE through a parent proxy, sockets were accumulated in CLOSE_WAIT state until descriptors ran out
+! Fix: file descriptor leak in HTTP proxy on the ftp:// request path
+! Fix: crash with illegal instruction on some platforms (e.g. some musl based Linux builds), caused by a memcpy on overlapping buffers
+! Fix: extip and ha (HAProxy PROXY protocol) parents are applied to SOCKSv5 UDP ASSOCIATE now
+! Fix: only socks5 and socks5+ parents are tried for UDP ASSOCIATE, other parent types can not be used for UDP
+! Fix: udppm through a SOCKSv5 parent did not work
+! Fix: -Ne and -Ni options were never applied, the option letter was not parsed; -Ne is not applied to the UDP ASSOCIATE reply anymore, -Ni is applied to it
+! Fix: -4 / -6 handling for UDP in socks; a single UDP association can use both IPv4 and IPv6 destinations now
+! Fix: a datagram with a null destination address is dropped now
+! Fix: DNS over TCP: a reply which did not fit a single read was never processed
+! Documentation: "How to apply ACLs to UDP traffic" added to HOWTO; authentication cache, ACL and UDP notes added to "Optimizing 3proxy for High Load" and to security recommendations
++ SOCKSv5 UDP: the destination of every datagram is authorized, so ACLs limiting the destination address, host name or port apply to UDP traffic now; the parent proxy and the external address are selected for the destination of the datagram and not for the UDP ASSOCIATE request
++ socks: -U option to control what happens when the destination changes within an UDP association: log it, authorize it, both (default) or neither
++ -C option (for TCP services) to terminate the session as soon as any of the sides closes the connection; by default the session is kept until both sides close it (TCP half-close)
++ timeouts: LINGER value added (11th, default 5), used to deliver buffered data after one of the sides has closed its sending side and as SO_LINGER value on outgoing connections

-3proxy-1.0.0 Вышел 22 Августа 2026
+3proxy-0.9.9 Вышел 20 Августа 2026
 
-Изменений в коде 3proxy нет, этот выпуск меняет только сборку, подписывание и публикацию пакетов.
-
-! Исправление: поддержка TLS, PCRE2 и PAM молча не включалась при сборке в системах, где /bin/sh не dash, то есть во всех дистрибутивах на основе RPM и в macOS; проверки наличия библиотек формировали тестовую программу через echo с escape-последовательностями, которые раскрывает только dash, поэтому все проверки завершались неудачно и возможности отключались без каких-либо сообщений
-! Исправление: пакеты rpm собирались в Ubuntu и требовали glibc 2.38, libssl.so.3 и libpcre2-8, которых нет ни в одном дистрибутиве на основе RPM, поэтому установить их было невозможно нигде; теперь они собираются в AlmaLinux 8, 9 и 10 и содержат метку el8, el9 или el10, что покрывает RHEL, AlmaLinux, Rocky и CentOS Stream соответствующей версии
-! Исправление: пакет rpm зависел от собственного интерпретатора /bin/3proxy, взятого из первой строки устанавливаемого файла конфигурации, и не устанавливался в el9 и el10, поскольку rpm приводит эту зависимость к /usr/bin/3proxy
-! Исправление: пакеты deb требовали glibc 2.38 и libssl3t64 и устанавливались только в Ubuntu 24.04 и новее; теперь они собираются в Ubuntu 22.04 и устанавливаются в Ubuntu 22.04 и новее, а также в Debian 12 и новее
-+ Подписанные репозитории apt и dnf публикуются на https://3proxy.org/repo/ в двух каналах: current, собираемый из ветки master, и lts, собираемый из ветки 0.9; подписываются и пакеты, и метаданные репозитория
-+ Двоичные файлы релиза публикуются с контрольными суммами SHA256, подписью OpenPGP и подтверждением происхождения сборки GitHub (build provenance attestation); образы docker также подписываются и снабжаются подтверждением
-+ Ключ подписи релизов — RSA-4096, опубликован в репозитории как 3proxy-release-key.asc; rpm версии 4.14 и более ранние вообще не могут импортировать ключ Ed25519, что лишило бы RHEL 8 и производные от него возможности проверки
-+ Пакеты воспроизводимы: повторная сборка релиза даёт побайтово идентичные файлы deb и rpm, все отметки времени берутся из даты сборки, записанной для релиза
-- Для 32-битной ARM (armhf) публикуется только пакет deb, в Enterprise Linux нет сборки для 32-битной ARM
+! Исправление: ответы DNS теперь проверяются: ответ с адреса, отличного от адреса сервера имён, которому был отправлен запрос, а также ответ с секцией вопроса, не совпадающей с запросом, отбрасываются; ранее оба принимались
+! Исправление: утечка сокетов при SOCKSv5 UDP ASSOCIATE через вышестоящий прокси, сокеты накапливались в состоянии CLOSE_WAIT до исчерпания дескрипторов
+! Исправление: утечка файловых дескрипторов в HTTP-прокси на пути обработки запроса ftp://
+! Исправление: аварийное завершение с недопустимой инструкцией на некоторых платформах (например, в некоторых сборках Linux на основе musl) из-за memcpy на перекрывающихся буферах
+! Исправление: родители типа extip и ha (HAProxy PROXY protocol) теперь применяются к SOCKSv5 UDP ASSOCIATE
+! Исправление: для UDP ASSOCIATE используются только родители socks5 и socks5+, остальные типы для UDP неприменимы
+! Исправление: udppm через вышестоящий прокси SOCKSv5 не работал
+! Исправление: опции -Ne и -Ni никогда не применялись, буква опции не разбиралась; -Ne больше не применяется к ответу на UDP ASSOCIATE, -Ni применяется к нему
+! Исправление: обработка -4 / -6 для UDP в socks; одна UDP-ассоциация теперь может использовать адреса назначения и IPv4, и IPv6
+! Исправление: датаграмма с нулевым адресом назначения теперь отбрасывается
+! Исправление: DNS поверх TCP: ответ, не помещавшийся в одно чтение, никогда не обрабатывался
+! Документация: в HOWTO добавлен раздел "Как применять ACL к UDP-трафику"; в "Optimizing 3proxy for High Load" и в рекомендации по безопасности добавлены заметки о кэше аутентификации, ACL и UDP
++ SOCKSv5 UDP: адрес назначения каждой датаграммы авторизуется, поэтому ACL, ограничивающие адрес назначения, имя хоста или порт, теперь применяются к UDP-трафику; вышестоящий прокси и внешний адрес выбираются для адреса назначения датаграммы, а не для запроса UDP ASSOCIATE
++ socks: опция -U для управления тем, что происходит при смене адреса назначения в рамках UDP-ассоциации: журналировать, авторизовать, и то и другое (по умолчанию) или ничего
++ Опция -C (для TCP-сервисов) завершает сессию, как только любая из сторон закрывает соединение; по умолчанию сессия сохраняется, пока соединение не закроют обе стороны (полузакрытие TCP)
++ timeouts: добавлено значение LINGER (11-е, по умолчанию 5), используется для доставки буферизованных данных после того, как одна из сторон закрыла свою передающую сторону, а также как значение SO_LINGER для исходящих соединений

-
-Configuration is where most of the risk lives. The security recommendations are
-kept in [doc/html/securityen.html](doc/html/securityen.html), published at
-<https://3proxy.org/securityen.html>: how to run the service, what the
-ACLs have to cover, and the settings whose defaults are safe only until
-something else is enabled alongside them.
-
-Read it before exposing a service. Recurring points from it:
-
-- Run unprivileged, never suid, and chroot where the platform allows.
-- Name the internal and external interfaces explicitly, and limit sources and
-  destinations with ACLs rather than relying on defaults.
-- Enabling IPv6 makes ACLs written in IPv4 incomplete: the same host is
-  reachable through an IPv4-mapped address, and the IPv6 loopback is an
-  address of its own.
-- Anything that terminates or intercepts TLS holds key material and sees full
-  request URLs; both the key and the logs need protecting.

-No changes in 3proxy code, this release only changes how packages are built, signed and published.
-
-! Fix: TLS, PCRE2 and PAM support was silently left out when 3proxy was built on a system whose /bin/sh is not dash, which is every RPM based distribution and macOS; the library checks built their test program with echo and escape sequences, which only dash expands, so every check failed and the features were dropped without a diagnostic
-! Fix: rpm packages were built on Ubuntu and required glibc 2.38, libssl.so.3 and libpcre2-8, which no RPM based distribution provides, so they could not be installed anywhere; they are built against AlmaLinux 8, 9 and 10 now and carry an el8, el9 or el10 tag, covering RHEL, AlmaLinux, Rocky and CentOS Stream of the same version
-! Fix: the rpm package depended on its own interpreter, /bin/3proxy, taken from the first line of the installed configuration file, and could not be installed on el9 or el10 because rpm resolves that dependency to /usr/bin/3proxy
-! Fix: deb packages required glibc 2.38 and libssl3t64 and installed on Ubuntu 24.04 and newer only; they are built against Ubuntu 22.04 now and install on Ubuntu 22.04 and later as well as Debian 12 and later
-+ Signed apt and dnf repositories are published at https://3proxy.org/repo/ in two channels: current, built from the master branch, and lts, built from the 0.9 branch; packages and repository metadata are both signed
-+ Release binaries are published with SHA256 checksums, an OpenPGP signature and a GitHub build provenance attestation; docker images are signed and attested as well
-+ The release signing key is an RSA-4096 key published as 3proxy-release-key.asc in the repository; rpm 4.14 and earlier can not import an Ed25519 key at all, which would leave RHEL 8 and its derivatives unable to verify anything
-+ Packages are reproducible: rebuilding a release produces byte identical deb and rpm files, every timestamp is derived from the build date recorded for the release
-- 32-bit ARM (armhf) is published as a deb package only, Enterprise Linux has no 32-bit ARM build

-<p>
-httpsrv answers requests itself instead of forwarding them. What it does with a
-request is decided by <code>http</code> rules written before the service, the way
-access rules are: the first rule whose host and URL both match handles the
-request. It is useful for a status page, a small static site, a block page for
-requests an ACL rejects, or a health check an upstream balancer can poll.
-</p><pre>
-http OPERATION HOST URL [PARAMETERS]
-</pre>
-<p>
-HOST is matched against the Host header, URL against the path with the query
-string removed. A minimal static site:
-</p><pre>
-auth iponly
-allow *
-
-http file * /           /usr/local/web/index.html
-http file * /*.html     "/usr/local/web/$1.html"
-http file * /css/*.css  "/usr/local/web/css/$1.css"
-http cache * /img/**    "/usr/local/web/img/$1" * 3600
-httpsrv -p80 -i127.0.0.1
-</pre>
-<p>
-<b>Patterns.</b> <code>*</code> stands for any run of characters within one
-element of the path and does not cross a <code>/</code>, so a rule cannot reach
-into a directory it did not name. <code>**</code> crosses them. Each star, and
-each group of a regular expression, is remembered in order: <code>$1</code>
-upwards stand for them in the path or location the rule builds, and
-<code>$0</code> for the whole request path. A <code>rewrite_host</code> rule
-uses the stars of its own host pattern instead, since that is what it is
-rewriting. With a PCRE build a pattern may be
-written as a regular expression with a <code>pcre:</code> prefix, for the URL and
-for the host alike:
-</p><pre>
-http file  * /d/*.txt       "/usr/local/web/$1.txt"
-http cache * "pcre:^/(.*)/pic/(.*)\.(gif|jpeg)$" "/usr/local/web/picts/$1/$2.$3"
-http file  status.example.com /**  "/usr/local/web/status/$1"
-http file  "pcre:^(www|web)\.example\.com$" /**  "/usr/local/web/$1"
-</pre>
-<p>
-Outside quotes a dollar begins the name of a file to include, so an argument
-holding one - a path built with <code>$1</code>, a regular expression anchored
-with <code>$</code> - is written in quotes, as above. <code>$$</code> stands for
-a single dollar and is not read as an include either.
-</p>
-<p>
-<b>Operations.</b>
-</p><pre>
-&#35; file - send the file, using sendfile/TransmitFile where the system can
-http file * /dl/**  "/usr/local/web/dl/$1"
-
-&#35; cache - read it into memory on the first request and answer from there
-http cache * /css/*.css "/usr/local/web/css/$1.css"
-
-&#35; redir - answer with a redirect, 302 unless a status is given
-http redir * /old/**  301 "https://example.org/$1"
-
-&#35; rewrite - change the path and hand the request to the rules after this one
-http rewrite * /alias/** "/w/$1"
-
-&#35; rewrite_host - the same for the host, which decides which rules match next
-http rewrite_host *.old.example ** "$1.new.example"
-
-&#35; reply - a status and nothing else
-http reply * /health**  200 "X-Health: ok"
-http reply * /down**    503 "Retry-After: 30"
-
-&#35; echo, data - describe the request, or generate content of a given size
-http echo * /echo**
-http data * /gen** size=1048576
-</pre>
-<p>
-<b>What a rule adds to the answer.</b> <code>file</code> and <code>cache</code>
-take, after the path, a content type, a max-age, headers to add and a status to
-answer with. Each may be left out or written as <code>*</code>:
-</p><pre>
-http OPERATION HOST URL PATH [TYPE [MAX-AGE [HEADERS [CODE]]]]
-
-&#35; type worked out from the name, cached by clients for an hour
-http file * /img/*.png "/usr/local/web/img/$1.png" * 3600
-
-&#35; a type of its own, and a header
-http file * /api/*.json "/usr/local/web/api/$1.json" application/json * "X-Api: 1"
-
-&#35; a file serving as the body of an error page
-http file * /err/** /usr/local/web/404.html text/html * * 404
-</pre>
-<p>
-HEADERS is one argument holding whole header lines, separated by a backslash and
-an n - the two characters, since a configuration line cannot carry a line
-ending. Quote it, headers contain spaces. A rule's headers and max-age go with
-whatever status that rule asked for, but not with a refusal the server itself
-decided on: a request for a file which is not there is answered 404 by the
-server, not by the rule.
-</p>
-<p>
-Types not known to the server are registered with
-<code>http_content_type</code>, and a type named by a rule is used whatever the
-name of the file says:
-</p><pre>
-http_content_type .webp image/webp
-http_content_type wasm  application/wasm
-</pre>
-<p>
-<b>Files and dates.</b> Only a full path is taken - a relative one would be read
-against whatever directory the service happens to be in - and a path holding
-<code>.</code> or <code>..</code> as an element, a line ending or a star is
-refused. On Windows a path must name a drive or a share (<code>"C:\web\$1"</code>
-or <code>"\\host\share\$1"</code>). A request which decodes to a path leaving the
-tree is refused before any of this. Every answer carries Last-Modified, and a
-request carrying If-Modified-Since is answered 304 with no body when the file
-has not changed.
-</p>
-<p>
-<b>Caching.</b> <code>cache</code> reads the file once and answers from memory
-afterwards; a file which has changed on disk is read again, and one larger than
-a megabyte is sent as <code>file</code> would. With a MAX-AGE the file is not
-looked at again for that long - the rule has already told clients the file may
-be treated as unchanged for that time - so a request costs nothing but the copy
-out. Without one every request stats the file and a change is picked up at once.
-</p>
-<p>
-<b>A block page.</b> A service which rejects a request with a redirect can send
-the client to an httpsrv running beside it:
-</p><pre>
-auth iponly
-deny * * "pcre:^(ads|track)[0-9]*\.example\.(com|net)$"
-allow *
-proxy -p3128 -i192.168.1.1
-
-flush
-auth iponly
-allow *
-http file * /**  /usr/local/web/blocked.html text/html * * 403
-httpsrv -p8080 -i127.0.0.1
-</pre>
-<p>
-<b>Both a site and a proxy.</b> A request may arrive the way it arrives at a
-site - a path, with the name in the Host header - or the way it arrives at a
-proxy, naming the whole URL, or the host alone with CONNECT. Both are read. A
-proxy-form request authenticates with Proxy-Authorization and is refused with
-407, the way a proxy refuses one; a site-form request uses Authorization and
-401. What answers it is decided by the rules either way.
-</p>
-<p>
-<code>proxypass</code> is the rule which answers by fetching, so one service can
-serve what it has and proxy the rest:
-</p><pre>
-auth iponly
-allow *
-http file * /local/** "/usr/local/web/$1"
-http proxypass * /**
-httpsrv -p8080
-</pre>
-<p>
-An access rule redirecting to the local proxy does the same without a rule for
-it. The chain with no address is what "the local proxy" is written as, and the
-second <code>allow</code> is what the proxy matches on the pass it makes itself,
-since a rule carrying the chain is not taken twice:
-</p><pre>
-auth iponly
-allow *
-parent 1000 http 0.0.0.0 0
-allow *
-http file * /local/** "/usr/local/web/$1"
-httpsrv -p8080
-</pre>
-<p>
-Authentication happens twice for the same reason - once for the service, once
-for the proxy - so a configuration which asks for credentials asks for them the
-way a proxy does.
-</p>
-<p>
-The access rules are read from the top on both passes, and the second one is
-where the request's destination is known. On the first pass the service is
-answering for itself, so an address or a port in a rule is matched against the
-address the client connected to; the name from the request is matched on both
-passes. On the second the destination is the one the request names, so rules
-written with an address, a port or a name decide what the proxy may fetch, and
-they decide it before it connects:
-</p><pre>
-auth iponly
-allow *
-parent 1000 http 0.0.0.0 0
-allow * * * 80,443
-deny *
-httpsrv -p8080
-</pre>
-<p>
-Everything reaches the rules, only ports 80 and 443 are fetched, and a
-<code>deny</code> written before the rule carrying the chain applies on both
-passes just the same. The connection to the server is kept for the next request and
-closed when that request goes elsewhere, or when the server has closed it in the
-meantime.
-</p>
-<p>
-<b>Connections.</b> A client asking in HTTP/1.1 gets a 1.1 answer and the
-connection is kept for the next request, unless it sent
-<code>Connection: close</code>; a 1.0 client has to ask for keep-alive. The
-connection is only kept when the length of the answer is known exactly, which is
-true of every operation except the administration pages, so those are always the
-last thing on a connection. A request body the server cannot read to its end -
-one sent chunked, or one larger than a megabyte - ends the connection too.
-</p>
-<p>
-<b>Administration.</b> The <code>admin</code> service is httpsrv with the pages
-of the administration interface already declared, see
-<a href="#ADMIN">Administering and information analysis</a>. Rules may be added
-before it in the same way, and are taken first.

-<p>
-A transparent proxy serves clients that were never configured to use one. A
-packet filter redirects their connections to 3proxy, and the
-<b>transparent</b> command tells the service to take the destination from the
-filter instead of from the request. Every other feature applies as usual:
-access rules, parent proxies, limits and logging all see the real destination.
-It works on Linux and on the BSDs. Since 1.0.1 it is part of the binary; before
-that it was the separate TransparentPlugin, and the <b>plugin</b> line it
-needed is no longer required.
-</p>
-<p>
-The command supplies both the address and the port the client was trying to
-reach, so a service can serve whatever was redirected to it rather than one
-port with one target.
-</p>
-<p>
-Without it a service has to get a destination from somewhere else: an HTTP
-proxy falls back to the <b>Host</b> header, and a port mapper uses the address
-it was configured with. Taking the destination from the filter is what makes
-the other protocols work, and what makes the address authoritative rather than
-something the client claimed.
-</p>
-<p>
-<b>tlspr</b> is the clearest case. Nothing reaches it at all unless traffic is
-redirected to it, or the clients resolve the names to it through DNS. With a
-redirection it gets the address as well as the name from the handshake, and
-that is what lets access rules be written with host names: the name from the
-handshake is matched, and the connection still goes to the address the client
-was going to. Without the address it would have to resolve the name itself,
-which is a second lookup and a second answer.

-On Linux 3proxy asks the kernel where the connection was going. On the BSDs it
-asks pf, which keeps the original destination in its state table, through
-<b>/dev/pf</b> - so <b>rdr</b> rules work, and 3proxy has to be able to read
-that device. Where a redirection leaves the destination on the socket instead,
-that is used: OpenBSD <b>divert-to</b> and FreeBSD <b>ipfw fwd</b> both do.
-</p>
-<p>
-The mechanism is chosen automatically, and <b>transparent</b> takes an
-argument for the installations that need to pin it: <b>auto</b> (the default),
-<b>netfilter</b>, <b>pf</b>, or <b>socket</b> for reading it off the socket. A
-mode the build has no code for is refused, so a configuration written for
-another platform fails where it is wrong instead of quietly doing something
-else.
-</p>
-
-<p><b>FreeBSD, NetBSD and OpenBSD, pf</b>. Redirect in <b>/etc/pf.conf</b>,
-excluding the address the proxy connects from:

-rdr pass on em0 inet proto tcp from ! 192.0.2.10 to any port 443 -&gt; 127.0.0.1 port 3143
-</pre>
-<p>
-Load with <b>pfctl -f /etc/pf.conf</b>. 3proxy looks the destination up in pf's
-state table, so it needs to read <b>/dev/pf</b>: either run it as root, or give
-its account access to that device.
-</p>
-
-<p><b>OpenBSD, divert-to</b> is an alternative which leaves the destination on
-the socket, and needs no access to <b>/dev/pf</b>:
-</p><pre>
-pass in on em0 inet proto tcp to any port 80  divert-to 127.0.0.1 port 3129
-pass in on em0 inet proto tcp to any port 443 divert-to 127.0.0.1 port 3143
-</pre>
-
-<p><b>FreeBSD, ipfw</b>. <b>fwd</b> delivers the connection locally without

-ipfw add fwd 127.0.0.1,3129 tcp from any to any 80  in recv em0
-ipfw add fwd 127.0.0.1,3143 tcp from any to any 443 in recv em0

-

-has no pf lookup, and macOS has neither <b>divert-to</b> nor ipfw to leave the
-address on the socket. Transparent proxying is not usable there, even though
-the commands exist in a macOS build.

-</p><pre>
-http ОПЕРАЦИЯ ХОСТ URL [ПАРАМЕТРЫ]

-<b>Шаблоны.</b> <code>*</code> означает любую последовательность символов внутри
-одного элемента пути и не пересекает <code>/</code>, поэтому правило не может
-попасть в каталог, который не назван в нём. <code>**</code> пересекает.
-Каждая звёздочка и каждая группа регулярного выражения запоминаются по порядку:
-<code>$1</code> и далее подставляют их в путь или адрес, который строит правило,
-<code>$0</code> - весь путь запроса. Правило <code>rewrite_host</code>
-использует звёздочки собственного шаблона хоста, поскольку переписывает именно
-его. В сборке с PCRE шаблон можно записать
-регулярным выражением с префиксом <code>pcre:</code> - и для URL, и для хоста:

-http file * /err/** /usr/local/web/404.html text/html * * 404
-</pre>
-<p>
-ЗАГОЛОВКИ - один аргумент, содержащий целые строки заголовков, разделённые
-обратной косой чертой и n - двумя символами, поскольку строка конфигурации не
-может содержать конец строки. Аргумент нужно брать в кавычки, в заголовках есть
-пробелы. Заголовки и max-age правила отправляются с тем кодом, который правило
-задало, но не с отказом, который решил вернуть сам сервер: на запрос
-отсутствующего файла 404 отвечает сервер, а не правило.
-</p>
-<p>
-Неизвестные серверу типы регистрируются командой
-<code>http_content_type</code>, а тип, названный в правиле, используется

-http_content_type .webp image/webp
-http_content_type wasm  application/wasm
-</pre>

-<b>Файлы и даты.</b> Принимается только полный путь - относительный отсчитывался
-бы от того каталога, в котором оказался сервис, - а путь с элементом
-<code>.</code> или <code>..</code>, концом строки или звёздочкой отвергается. В
-Windows путь должен указывать диск или сетевой ресурс (<code>"C:\web\$1"</code>
-или <code>"\\host\share\$1"</code>). Запрос, который декодируется в путь за
-пределами дерева, отвергается раньше всего этого. Каждый ответ содержит
-Last-Modified, а запрос с If-Modified-Since получает 304 без тела, если файл не
-изменился.
-</p>
-<p>
-<b>Кэширование.</b> <code>cache</code> читает файл один раз и дальше отвечает из
-памяти; изменившийся на диске файл читается заново, а файл больше мегабайта
-отдаётся так же, как это сделал бы <code>file</code>. При заданном MAX-AGE файл
-не проверяется в течение этого времени - правило уже сообщило клиентам, что
-столько файл можно считать неизменным, - и запрос стоит только копирования
-наружу. Без MAX-AGE каждый запрос делает stat, и изменение подхватывается сразу.
-</p>
-<p>
-<b>Страница блокировки.</b> Сервис, отклоняющий запрос редиректом, может
-отправить клиента на httpsrv, работающий рядом:
-</p><pre>
-auth iponly
-deny * * "pcre:^(ads|track)[0-9]*\.example\.(com|net)$"
-allow *
-proxy -p3128 -i192.168.1.1
-
-flush
-auth iponly
-allow *
-http file * /**  /usr/local/web/blocked.html text/html * * 403
-httpsrv -p8080 -i127.0.0.1
-</pre>
-<p>
-<b>И сайт, и прокси.</b> Запрос может прийти так, как приходит на сайт - путь,
-имя в заголовке Host, - или так, как приходит на прокси: с полным URL, либо, для
-туннеля, с одним именем хоста в CONNECT. Читается и то, и другое. Запрос в форме
-для прокси аутентифицируется через Proxy-Authorization и отклоняется кодом 407,
-как это делает прокси; запрос в форме для сайта - через Authorization и 401. Чем
-он будет обработан, в обоих случаях решают правила.
-</p>
-<p>
-<code>proxypass</code> - правило, которое отвечает, забирая ресурс, поэтому один
-сервис может отдавать своё и проксировать остальное:
-</p><pre>
-auth iponly
-allow *
-http file * /local/** "/usr/local/web/$1"
-http proxypass * /**
-httpsrv -p8080
-</pre>
-<p>
-Правило доступа с перенаправлением на локальный прокси делает то же самое без
-отдельного правила. Цепочка без адреса и означает "локальный прокси", а второй
-<code>allow</code> - то, с чем совпадает сам прокси на своём проходе, так как
-правило с цепочкой второй раз не берётся:
-</p><pre>
-auth iponly
-allow *
-parent 1000 http 0.0.0.0 0
-allow *
-http file * /local/** "/usr/local/web/$1"
-httpsrv -p8080
-</pre>
-<p>
-Аутентификация по той же причине происходит дважды - для сервиса и для прокси, -
-поэтому конфигурация, требующая учётных данных, запрашивает их так, как это
-делает прокси.
-</p>
-<p>
-Правила доступа просматриваются с начала на обоих проходах, и назначение запроса
-известно на втором. На первом сервис отвечает сам за себя, поэтому адрес или порт
-в правиле сопоставляется с адресом, на который подключился клиент; имя из запроса
-сопоставляется на обоих проходах. На втором назначение - то, которое названо в
-запросе, поэтому правила с адресом, портом или именем определяют, что прокси
-разрешено забрать, и определяют это до установления соединения:
-</p><pre>
-auth iponly
-allow *
-parent 1000 http 0.0.0.0 0
-allow * * * 80,443
-deny *
-httpsrv -p8080
-</pre>
-<p>
-До правил доходит всё, забираются только порты 80 и 443, а <code>deny</code>,
-записанный до правила с цепочкой, действует на обоих проходах точно так же. Соединение с сервером сохраняется для следующего запроса и
-закрывается, если следующий запрос идёт в другое место или если сервер за это
-время его закрыл.
-</p>
-<p>
-<b>Соединения.</b> Клиент, обратившийся по HTTP/1.1, получает ответ 1.1, и
-соединение сохраняется для следующего запроса, если он не прислал
-<code>Connection: close</code>; клиенту 1.0 нужно запросить keep-alive явно.
-Соединение сохраняется только тогда, когда длина ответа известна точно - это
-верно для всех операций, кроме страниц администрирования, поэтому они всегда
-последнее, что отдаётся в соединении. Тело запроса, которое сервер не может
-дочитать до конца - присланное chunked или размером больше мегабайта, - тоже
-завершает соединение.
-</p>
-<p>
-<b>Администрирование.</b> Сервис <code>admin</code> - это httpsrv с уже
-объявленными страницами интерфейса администрирования, см.
-<a href="#ADMIN">Администрирование и анализ информации</a>. Правила можно
-добавлять перед ним так же, и они проверяются первыми.

-Linux и BSD. С версии 1.0.1 встроено в бинарник, раньше это был отдельный
-TransparentPlugin, и строка <b>plugin</b> больше не нужна.
-</p>
-<p>
-Команда даёт и адрес, и порт назначения, поэтому сервис обслуживает всё, что
-на него перенаправлено, а не один порт с одним адресом назначения.
-</p>
-<p>
-Без неё сервис берёт адрес откуда-то ещё: HTTP-прокси - из заголовка
-<b>Host</b>, порт-маппер - из своей конфигурации. Именно получение адреса от
-фильтра позволяет работать с остальными протоколами и делает адрес
-достоверным, а не заявленным клиентом.
-</p>
-<p>
-Нагляднее всего это с <b>tlspr</b>. Без перенаправления трафика (или без
-резолва имён на него через DNS) на него вообще ничего не попадёт. С
-перенаправлением он получает и имя из TLS handshake, и адрес назначения -
-именно это позволяет писать правила доступа по именам хостов: имя из handshake
-проверяется в ACL, а соединение идёт на тот адрес, куда шёл клиент. Без адреса
-пришлось бы резолвить имя самостоятельно, то есть делать ещё один запрос и
-получать ещё один ответ.
-</p>
-<p>
-Конфигурация для веб- и TLS-трафика:
-</p><pre>
-log /var/log/3proxy.log D
-auth iponly
-allow *
-
-&#35; для сервисов ниже адрес назначения берётся из перенаправления
-transparent
-
-&#35; обычный веб-трафик, перенаправленный сюда с порта 80
-proxy -p3129 -e192.0.2.10
-
-&#35; TLS, перенаправленный сюда с порта 443: без этого у tlspr было бы только
-&#35; имя из handshake, а так есть и адрес
-tlspr -p3143 -e192.0.2.10
-
-notransparent
-</pre>
-<p>
-<b>-e</b> задаёт сервисам собственный адрес для исходящих соединений. Именно
-этот адрес исключается в правилах перенаправления, и это исключение не даёт
-соединениям самого прокси попасть обратно в него. Без исключения соединение,
-которое 3proxy устанавливает к серверу назначения, попадает под то же правило,
-возвращается в 3proxy, и трафик зацикливается. Можно вместо этого запускать
-3proxy под отдельной учётной записью и исключать её - так лучше, если у машины
-один адрес.

-В Linux 3proxy спрашивает у ядра, куда шло соединение. В BSD он спрашивает у pf,
-который хранит исходный адрес назначения в таблице состояний, через
-<b>/dev/pf</b> - поэтому работают правила <b>rdr</b>, и 3proxy должен иметь
-доступ к этому устройству. Если перенаправление оставляет адрес на самом сокете,
-используется он: так делают OpenBSD <b>divert-to</b> и FreeBSD <b>ipfw fwd</b>.
-</p>
-<p>
-Механизм выбирается автоматически, а команда <b>transparent</b> принимает
-аргумент для случаев, когда его надо зафиксировать: <b>auto</b> (по умолчанию),
-<b>netfilter</b>, <b>pf</b> или <b>socket</b> для чтения адреса с сокета. Режим,
-которого нет в сборке, отвергается, поэтому конфигурация, написанная для другой
-платформы, не запустится вместо того, чтобы молча делать что-то другое.
-</p>
-
-<p><b>FreeBSD, NetBSD, OpenBSD, pf</b>. Перенаправление в <b>/etc/pf.conf</b> с

-</pre>
-<p>
-Загружается через <b>pfctl -f /etc/pf.conf</b>. 3proxy ищет адрес назначения в
-таблице состояний pf, поэтому ему нужен доступ на чтение к <b>/dev/pf</b>: либо
-запуск от root, либо права на устройство для его учётной записи.
-</p>
-
-<p><b>OpenBSD, divert-to</b> - альтернатива, оставляющая адрес на сокете, доступ
-к <b>/dev/pf</b> при этом не нужен:
-</p><pre>
-pass in on em0 inet proto tcp to any port 80  divert-to 127.0.0.1 port 3129
-pass in on em0 inet proto tcp to any port 443 divert-to 127.0.0.1 port 3143
-</pre>
-
-<p><b>FreeBSD, ipfw</b>. <b>fwd</b> доставляет соединение локально, не переписывая

+<h3>3proxy TransparentPlugin (Linux/BSD only)</h3>
 
-Transparent proxying is part of 3proxy itself since 1.0.1. It was the separate
-TransparentPlugin before that, and the <b>plugin</b> line that used to load it
-is no longer needed: the <b>transparent</b> and <b>notransparent</b> commands
-are always available on the platforms that can redirect a connection.
-
-<p>
-It turns 3proxy into a transparent proxy for virtually any TCP-based protocol,
-with the rest of 3proxy applying as usual - redirections, parent proxies, ACLs,
-traffic limitations and logging. The destination IP and port come from the
-packet filter that redirected the connection, and are used as the target of the
-proxied connection.
-</p>
+This plugin can turn 3proxy into a transparent proxy for virtually any TCP-based protocol
+and use all 3proxy features - redirections, parent proxies, ACLs, traffic limitations,
+etc. The TransparentPlugin takes the destination IP:port from Linux and uses this
+information as the target IP in the proxy. An example usage:
 
 <pre>
+plugin /path/to/TransparentPlugin.ld.so transparent_plugin
 log /path/to/log
 auth iponly

 </pre>
+Now, any TCP traffic transparently redirected to port 12345 will be routed via
+the parent SOCKSv5 proxy and logged; all URLs for web requests are visible in logs.
+The parameters '127.0.0.1 11111' in this case are not used and are overwritten by
+the destination IP:port for each transparent connection.
 
-<p>
-Any TCP traffic redirected to port 12345 is routed through the parent SOCKSv5
-proxy and logged, with the URLs of web requests visible in the log. The
-'127.0.0.1 11111' arguments are not used in that case: they are replaced by the
-destination the client was trying to reach.
-</p>
-
-<p>
-The destination is looked up in pf on the BSDs, through <b>/dev/pf</b>, and
-asked of the kernel on Linux; a redirection that leaves the address on the
-socket is used where there is one. <b>transparent</b> takes an optional
-<b>auto</b>, <b>netfilter</b>, <b>pf</b> or <b>socket</b> to pin that choice.
-</p>
-<p>
-The redirection rules must not match the connections 3proxy itself makes, or
-the traffic returns to the proxy and loops. Give the service an address to
-connect from with <b>-e</b> and exclude it in the rules, or run 3proxy as its
-own account and exclude that account.
-</p>
-
-<p>
-Redirection rules for iptables, nftables, firewalld, ufw and pf are in

+Плагин превращает 3proxy в транспарентный прокси для практически любых TCP-соединений
+и позволяет прозрачно для клиентов использовать весь фунционал прокси - редиректоры,
+родительские прокси, ACLи, ограничения трафика. TransparentPlugin получает IP:port
+назначения от Linux  и использует эту информацию в качестве конечного адреса назначения.

-Любой TCP-трафик, перенаправленный на порт 12345, пойдёт через родительский
-SOCKSv5 прокси и будет залогирован, URL веб-запросов видны в логе. Аргументы
-'127.0.0.1 11111' в этом случае не используются: они заменяются адресом, к
-которому обращался клиент.
-</p>
-
-<p>
-В BSD адрес назначения ищется в pf через <b>/dev/pf</b>, в Linux запрашивается у
-ядра; если перенаправление оставляет адрес на сокете, используется он. Команда
-<b>transparent</b> принимает необязательный аргумент <b>auto</b>,
-<b>netfilter</b>, <b>pf</b> или <b>socket</b>, чтобы зафиксировать выбор.
-</p>
-<p>
-Правила перенаправления не должны попадать на соединения, которые устанавливает
-сам 3proxy, иначе трафик возвращается в прокси и зацикливается. Задайте сервису
-адрес для исходящих соединений через <b>-e</b> и исключите его в правилах, либо
-запускайте 3proxy под отдельной учётной записью и исключайте её.

+будут прологгированы и перенаправлены в родительский SOCKSv5 proxy, при этом для

 <li>Always limit connections to the internal network and localhost (to 127.0.0.1 and

 BIND method with the external interface IP address to be allowed.
-<li>Services resolve IPv4 only unless told otherwise ('-4' is the default). Enabling
-IPv6 with '-6', '-46' or '-64' makes every ACL written in IPv4 incomplete, because the
-same host can be asked for in another way. A proxy that denies 127.0.0.1 but has IPv6
-enabled still reaches that host as '::ffff:127.0.0.1', and reaches the machine again as
-'::1', which is a different address the IPv4 rule never mentioned. When IPv6 is enabled,
-deny the mapped form '::ffff:0:0/96' as well unless it is needed, and deny the IPv6
-addresses that correspond to whatever the IPv4 rules protect: '::1' and '::' for the
-local machine, 'fe80::/10' for link-local and 'fc00::/7' for unique local addresses.
-Denying the IPv4 spelling alone is not enough.
-<li>With '-46' or '-64' a name resolves to either family, so a target ACL that names
-only one of a host's addresses does not limit that host. Names are resolved into

-anyone is a traffic amplifier. Do not configure them on a public service.
-<li>'ssl_server_ca_key' is the private key of a certificate authority that clients have
-been told to trust. Anyone who obtains it can impersonate any site to those clients, so
-protect it as a signing key and use a CA created for this purpose only, never one that
-is trusted for anything else. Restrict the 'ssl_certcache' directory as well: it holds
-the certificates generated from that key.
-<li>Interception ('ssl_mitm') ends the guarantee the client believes it has. The full

-proxy and reaches the log, where a plain CONNECT would have shown only a host and a
-port. Treat those logs accordingly.
-<li>Certificates generated for interception by a build against wolfSSL carry no key
-identifiers, because that library cannot generate certificate extensions, and a client
-verifying strictly (OpenSSL 'x509_strict', which recent Python enables by default)
-rejects them. Builds against OpenSSL generate them. Where they are missing, turning
-verification off in the client removes the protection interception was supposed to
-preserve; use an OpenSSL build instead.
-<li>Regular expression rules ('pcre', 'pcre_rewrite') are matched without

- \fBMAX-AGE\fR is a number of seconds, and is sent as Cache-Control: max-age.
-Without it, or with \fB*\fR, nothing is said about caching.
-.br
- \fBHEADERS\fR is one argument holding whole header lines, separated by a
-backslash and an n \- the two characters, since a configuration line cannot
-carry a line ending. Each becomes a real line ending in the answer. Quote the
-argument if any header holds a space, which they usually do.
-.br
- \fBCODE\fR is the status to answer with instead of 200, which is how a file
-serves as the body of an error page.
-.br
- A rule's headers and MAX-AGE go with whatever status that rule asked for. They
-are not sent with a refusal the server itself decided on: a request for a file
-which is not there is answered 404 by the server, not by the rule.
-.br
- \fBfile\fR and \fBcache\fR send Last-Modified, and answer a request carrying
-If-Modified-Since with 304 and no body when the file has not changed since the
-time it names. All three date formats HTTP allows are read; one which cannot be
-read is treated as no date at all. A rule answering with a CODE of its own is
-answering something other than the file, so it is never turned into a 304.

-
-.SS Patterns
-A URL is matched with stars, or with a regular expression when it carries a
-\fBpcre:\fR prefix (\fBregex:\fR is taken as well). A host is matched the way an
-access list matches one, and takes the same prefix.
-.br
- \fB*\fR stands for any run of characters within one element of the path: it
-does not cross a \fB/\fR, so a rule cannot reach into a directory it did not
-name.
-.br
- \fB**\fR crosses them, and is what a rule which should match everything below a
-point, or everything at all, is written with.
-.br
- Each star, and each group of a regular expression, is remembered in the order
-it appears. \fB$1\fR upwards stand for them in the path or location a rule
-builds, and \fB$0\fR for the whole request path.
-.br
- Outside quotes a dollar begins the name of a file to include, so an argument
-holding one \- a path or location built with \fB$1\fR, a regular expression
-anchored with \fB$\fR \- is written in quotes. \fB$$\fR stands for a single
-dollar and is not read as an include either, which is how a dollar reaches a
-rule as text.
-
-.SS Both a site and a proxy
-A request may arrive the way it arrives at a site, naming a path and a host in
-the Host header, or the way it arrives at a proxy, naming the whole URL, or, for
-a tunnel, the host alone with CONNECT. Both are read. A request in the proxy
-form authenticates with Proxy-Authorization and is refused with 407, as a proxy
-refuses one; a request in the site form uses Authorization and 401.
-.br
- What answers a request is still decided by the rules. \fBproxypass\fR is the
-rule which answers by fetching, so a service can serve what it has and proxy the
-rest:
-.br
- http file * /local/** "/usr/local/web/$1"
-.br
- http proxypass * /**
-.br
- httpsrv -p8080
-.br
- The same happens without a rule for it where an access rule redirects to the
-local proxy, which is written as a chain of no address: the rules are asked
-first, and a request none of them answers is fetched.
-.br
- allow *
-.br
- parent 1000 http 0.0.0.0 0
-.br
- allow *
-.br
- The second \fBallow\fR is what the proxy matches on the pass it makes itself:
-a rule carrying the chain is not taken twice. Authentication happens twice for
-the same reason, once for the service and once for the proxy, so a configuration
-asking for credentials asks for them as a proxy does.
-.br
- The access rules are read from the top on both passes, and it is the second
-pass which describes where the request is going. On the first one the service is
-answering for itself, so the destination an address or a port is matched against
-is the address the client connected to; the name from the request is matched on
-both. On the second the destination is the one the request names, so rules
-written with an address, a port or a name decide what the proxy is allowed to
-fetch, and they decide it before the connection is made:
-.br
- allow *
-.br
- parent 1000 http 0.0.0.0 0
-.br
- allow * * * 80,443
-.br
- deny *
-.br
- Everything reaches the rules, and only ports 80 and 443 are fetched. A rule
-before the one carrying the chain applies on both passes just the same, so a
-\fBdeny\fR written there stops the request as well.
-.br
- The connection to the server is kept for the request after it, and closed when
-the request after it goes somewhere else, or when the server has closed it in
-the meantime. A tunnel is fetched by the proxy code as well, which means the
-connection carrying it belongs to that request alone.
-
-.SS Connections
-An answer is sent as HTTP/1.1 to a client which asked in HTTP/1.1, and the
-connection is kept for the next request unless the client sent
-\fBConnection: close\fR. A 1.0 client gets a 1.0 answer, and the connection is
-kept only when it asked with \fBConnection: keep-alive\fR.
-.br
- The connection is kept only when what was sent is framed exactly: every
-operation but the administration pages states a length, or sends a chunked body
-a 1.1 client can read, so the pages of \fBadmin\fR are always the last thing on
-a connection. A request body which cannot be read to its end ends the connection
-as well: one sent with \fBTransfer-Encoding\fR, which this server does not read,
-and one longer than a megabyte, which it will not.
-
-.SS Paths a rule builds
-The path a rule builds is used as it is, so it is refused rather than corrected
-when it is not a plain full path. A relative path is refused: it would be read
-against whatever directory the service happens to be in. So is one holding
-\fB.\fR or \fB..\fR as an element, a carriage return, a newline or a star. On
-Windows a path must name a drive or a share, and is converted to the extended
-\\\\?\\ form and opened through the wide interface, so a long path works.
-.br
- A request is checked before any of this: a path which decodes to one leaving
-the tree is refused outright.
-
-.SS Examples

- http file example.com /my/webpath/*.html "/usr/local/web/$1.html"
-.br
- http cache example.com "pcre:^/(.*)/pic/(.*)\.(gif|jpeg)$" "/usr/local/web/picts/$1/$2.$3"

- http redir * /old/** 301 "https://example.org/$1"

-    python3 tests/run.py --keep              # keep the configurations and logs
-
-Python 3.6 or later and a built 3proxy are the only requirements: the suite
-is standard library throughout, so it runs wherever 3proxy builds. The TLS
-case additionally wants `openssl` on PATH to generate its key material, and
-skips itself when that is missing or the build has no TLS support. With no
-`--bin` it looks in `bin/`, then `build/bin/`, then the per-configuration
-directories a multi-configuration CMake generator uses.
-
-The proxy under test is also the origin server the tests talk to: the `http`
-command's `echo` operation reports back how a request arrived - method, path,
-query, host, and the source port it came from - and `data` generates a body
-of a requested size, framing, status and pace. So a case can state what a
-proxy should do to a request and then read off what actually reached the
-other side.
-
-## Adding a case
-
-A case is a module under `cases/` exporting `run(t)`. It writes the
-configurations it needs, starts them, and says what it expects:
-
-```python
-def run(t):
-    srv = t.free_port()
-    t.start("my_case", f"""
-        log
-        auth iponly
-        allow *
-        http * /echo echo
-        httpsrv -p{srv}
-    """, ports=[srv])
-
-    r = t.http(f"http://127.0.0.1:{srv}/echo")
-    t.eq(200, r.status, "the server answers")
-    t.contains(r, "method=GET", "the method is reported")
-```
-
-Servers are stopped for you when the case ends, whether or not it passed.
-
-`t` offers `http()` (direct, through an HTTP proxy, or over a CONNECT
-tunnel), `socks_http()` and `socks_connect()` for SOCKS4 and SOCKS5,
-`socks_udp_associate()`, `raw()` for bytes a real client would never send,
-and `run_config()` for configurations that are meant to be rejected.
-Assertions are `eq`, `ne`, `contains`, `not_contains`, `in_range`,
-`not_in_range`, plus `ok`, `fail` and `skip`. `harness.field()` and
-`int_field()` pull a single line out of an `echo` reply.
-
-For services with no TCP port to connect to, `t.udp_echo()` starts an echo
-server, `t.udp_exchange()` sends a datagram, `t.wait_udp()` waits for a UDP
-service to start answering, `t.socks_udp()` carries one through a SOCKS
-association, and `t.dns_query()` asks a DNS server for an A record.
-
-`t.certs()` generates a CA, a second unrelated CA, and a certificate for
-127.0.0.1, once per run and inside the run's temporary directory, so no key
-material lives in the tree. `t.https()`, `t.tls_proxy_http()` and
-`t.socks_http()` reach a server through TLS, a TLS-wrapped proxy, or SOCKS.
-Log records are written when a connection finishes rather than when the
-reply arrives, so assert on them through `t.wait_output(server, text)`.
-
-Note that access rules accumulate until `flush`, so a service section that
-means to stand on its own should start with one - otherwise an earlier
-`allow *` matches first and the rule under test is never reached.
-
-## What is not covered yet
-
-41 of the 112 configuration commands appear in a test, and the count says
-nothing about service options: the IPv6 case, for instance, exercises -4,
--6, -46, -64 and -i without adding a command to it. What follows is
-roughly the order worth working through: how much of the product a gap
-covers, and how much of a fixture it needs.
-
-### Traffic limits and accounting
-
-`bandlimin` `bandlimout` `nobandlimin` `nobandlimout` `connlim` `noconnlim`
-`countin` `countout` `countall` and the `no*` forms, `maxconn`.
-
-Cheap and worth doing first: `data?size=` and a stopwatch measure a
-bandwidth limit, and the admin counters page already shows what a counter
-holds. `countin` appears in a configuration today but nothing checks that it
-counts. `connlim` and `maxconn` need concurrent connections.
-
-### The mail proxies
-
-`pop3p` `smtpp` `imapp`, and `ftppr`.
-
-The largest gap by volume: four protocol implementations with no coverage at
-all. Each needs a scripted server that speaks enough of the protocol,
-including the multi-line and challenge forms - a POP3 or IMAP server that
-only answers `+OK` will not exercise the interesting paths. Worth the
-fixture: this is also where known parent-chaining trouble lives, since
-`clientnegotiate()` has no case for R_POP3, R_SMTP or R_FTP.
-
-### Access rules and chaining
-
-`redirect` `weight` `parentretries` `force` `noforce` `include` `nolog`.
-
-Also the parts of an ACE never exercised: source addresses and masks, port
-ranges, time and weekday fields, and operation lists beyond the single
-`HTTP_CONNECT` used today. `weight` needs several parents and enough
-requests to see the split.
-
-### IPv6, what is left of it
-
-`tests/cases/ipv6.py` covers listening on `::1`, proxying to and from it,
-SOCKS with an IPv6 destination, rules naming an IPv6 address, and which
-family each of `-4 -6 -46 -64` will use. Still open: `extip` with an IPv6 CIDR, whose
-randomisation path has no coverage.
-
-### Authentication
-
-`authcache` `radius` `authnserver`, and the auth methods beyond `iponly` and
-`strong`: `none`, `nbname`, `dnsname`. `radius` needs a server to answer.
-
-### Plugins
-
-`plugin`. Nothing loads one, though `StringsPlugin`, `TrafficPlugin`,
-`TransparentPlugin` and `FilePlugin` are built in CI. StringsPlugin matters
-most: the admin string table is kept byte-compatible for it deliberately,
-and nothing proves that.
-
-### Logging
-
-`logformat` `rotate` `archiver` `logdump`.
-
-Tests read the log as free text, so a reordered field would pass every check
-here and break every downstream parser. `rotate` and `archiver` need control
-of the clock or a long run.
-
-### TLS options
-
-About 25 `ssl_client_*` and `ssl_server_*` commands: SNI, ALPN, protocol
-versions, cipher lists, `ssl_client_cert` and `ssl_client_key` for mTLS,
-`ssl_*_verify` and `ssl_*_no_verify`. The certificate fixture exists, so
-these are mostly a matter of writing them.
-
-### Process and lifecycle
-
-`daemon` `chroot` `setuid` `setgid` `pidfile` `stacksize` `backlog` `monitor`
-`system` `include` `timeouts` `maxseg` `external` `delimchar`
-`filtermaxsize`. Several need root or change the process in ways a test
-runner has to survive; `include`, `timeouts` and `pidfile` do not, and are
-easy.
-
-Reload is worth a case of its own: the admin page returns "Reload scheduled"
-and nothing checks that the configuration is re-read, that a changed rule
-takes effect, or that services come back.
-
-### DNS
-
-`fakeresolve` `nscache6` `dialer`.
-
-### Known limitations, deliberately not asserted
-
-A request rewrite that changes the method or the authority is ignored, and
-the manual says so; a test that pinned the current behaviour would have to
-change when that does. An intercepted certificate is verified strictly where the build can
-generate the key identifiers, and the case skips that one check on a wolfSSL
-build, which cannot. If wolfSSL gains the ability, the skip should go.
