+1. Здесь не место для вопросов, касающихся компьютерной грамотности и навыков использования ОС
+2. Здесь не место для вопросов "у меня не работает" без технических подробностей
+3. Здесь не место для вопросов "как мне открыть ютуб", "что писать в ...", "перестало открываться".
+4. Здесь не место для обсуждения сборок
+5. Вирусов здесь нет. У вас либо чья-то сборка, либо ваш антивирус давно пора отправить на покой. Антивирусы в основном жалуются на upx и windivert, которые убраны НЕ будут. upx - это паковщик для сокращения требуемого места на openwrt, windivert - замена iptables для windows, потенциальный инструмент хакера или компонент зловредной программы, но сам по себе вирусом не является. Не согласны - удаляйте софт. За агрессивные наезды "почему автор распространяет вирусы" молча схватите бан.
+
+Все означенное обсуждать в дискуссиях или на форумах.
+При нарушении будет закрываться или конвертироваться в дискуссии.
+Issue только для обсуждения проблем самого софта. Неработа стратегии или ваше неумение настроить - это ваша проблема, а не проблема софта.
+Однокнопочные решения дают только сборщики, поэтому "открытие сайта" не является функцией программы, и нет смысла жаловаться, что он не открывается. Но можно это обсудить в дискуссиях. Не захламляйте issues !

-!!! Эта инструкция написана еще до включения wireguard в ядро linux.

-!!! для преодоления DPI. Автор не преследует цели поддерживать готовые патчи для актуальных версий.
-!!! Вместо патчинга гораздо проще использовать навесное решение ipobfs.
-
-Посвящено возможной блокировке в РФ VPN протоколов через DPI.
-Предпосылками являются последние законодательные акты и во всю сочащиеся "секретные" записки.
-В РФ разрабатываются и готовятся к применению более продвинутые решения по блокировке трафика.
-Вполне вероятно будут резать стандартные VPN протоколы. Нам надо быть к этому готовыми.
-
-Один из возможных и перспективных путей решения данного вопроса - кустомная модификация
-исходников VPN с целью незначительного изменения протокола, ломающего стандартные модули обнаружения в DPI.
-Это относительно сложно, доступно только для гиков.
-Никто не будет разрабатывать специальные модули обнаружения в DPI, если только кто-то не сделает простое и
-удобное решение для всех, и его станут широко применять. Но это маловероятно, и даже если и так,
-то всегда можно модифицировать протокол чуток по другому. Делать моды для DPI несравненно дольше
-и дороже, чем клепать на коленке изменения протокола для wireguard.
-
-
-ЗАМЕЧЕНИЕ : альтернативой модификации конечного софта для VPN является использование "навесных"
-обфускаторов. см : https://github.com/bol-van/ipobfs
-
-
-Рассмотрю что нам надо пропатчить в wireguard. Модифицированный wireguard проверен на виртуалках
-с десктопным linux, он работает, сообщения в wireshark действительно не вписываются в стандартный
-протокол и не опознаются.
-
-Wireguard протокол очень простой. Все сообщения описаны в messages.h
-Поставим себе целью сделать 2 простые модификации :
-1) Добавим в начало всех сообщений немного мусора, чтобы изменить размер сообщений и смещения полей
-2) Изменим коды типов сообщений
-Этого может быть вполне достаточно для обмана DPI

-Вот и весь патчинг. Полный patch (версия wireguard 0.0.20190123) лежит в 010-wg-mod.patch.
-Патчинг кода - самое простое. Для десктопного linux дальше все просто.
-Пересобираем через make, устанавливаем через make install, перегружаем
-модуль wireguard, перезапускаем интерфейсы, и все готово.
-
-Настоящий геморой начнется когда вы это попытаетесь засунуть на роутер под openwrt.
-Одна из больших проблем linux - отсутствие совместимости драйверов на уровне бинариков.
-Поэтому собирать необходимо в точности под вашу версию ядра и в точности под его .config.
-Вам придется либо полностью самостоятельно собирать всю прошивку, либо найти SDK в точности
-от вашей версии прошивки для вашей архитектуры и собрать модуль с помощью этого SDK.
-Последний вариант более легкий.
-Для сборки вам понадобится система на linux x86_64. Ее можно установить в виртуалке.
-Теоретически можно пользоваться WSL из win10, но на практике там очень медленное I/O,
-по крайней мере на старых версиях win10. Безумно медленное. Будете собирать вечность.
-Может в новых win10 что-то и улучшили, но я бы сразу расчитывал на полноценный linux.
-
-Находим здесь вашу версию : https://downloads.openwrt.org/
-Скачиваем файл openwrt-sdk-*.tar.xz или lede-sdk-*.tar.xz
-Например : https://downloads.openwrt.org/releases/18.06.2/targets/ar71xx/generic/openwrt-sdk-18.06.2-ar71xx-generic_gcc-7.3.0_musl.Linux-x86_64.tar.xz
-Если ваша версия непонятна или стара, то проще будет найти последнюю прошивку и перешить роутер.
-Распаковываем SDK. Следующими командами можно собрать оригинальный вариант wireguard :
-
-# scripts/feeds update -a
-# scripts/feeds install -a
-# make defconfig
-# make -j 4 package/wireguard/compile
-
-Сборка будет довольно долгой. Ведь придется подтащить ядро, собрать его, собрать зависимости.
-"-j 4" означает использовать 4 потока. Впишите вместо 4 количество доступных cpu cores.
-
-Получим следующие файлы :
-
-openwrt-sdk-18.06.2-ar71xx-generic_gcc-7.3.0_musl.Linux-x86_64/bin/targets/ar71xx/generic/packages/kmod-wireguard_4.9.152+0.0.20190123-1_mips_24kc.ipk

-
-Но это будет оригинальный wireguard. Нам нужен патченый.
-Установим quilt и mc для нормального редактора вместо vim :
-
-# sudo apt-get update
-# sudo apt-get install quilt mc
-
-# make package/wireguard/clean
-# make package/wireguard/prepare V=s QUILT=1
-
-

-# quilt push -a
-# quilt new 010-wg-mod.patch
-# export EDITOR=mcedit
-
-Далее будет открываться редактор mcedit, в который нужно вносить изменения в каждый файл :
-
-# quilt edit messages.h
-# quilt edit cookie.c
-# quilt edit noise.c
-# quilt edit send.c
-# quilt diff
-# quilt refresh

-
-Выходим в корень SDK.
-
-# make package/wireguard/compile V=99
-
-Если не было ошибок, то получили измененные ipk.
-Патч можно зафиксировать в описании пакета :

-затем
-# make package/wireguard/compile
-
-Если нужно поменять версию wireguard, то идите в
-openwrt-sdk-18.06.2-ar71xx-generic_gcc-7.3.0_musl.Linux-x86_64/feeds/base/package/network/services/wireguard/Makefile
-поменяйте там версию в PKG_VERSION на последнюю из : https://git.zx2c4.com/WireGuard
-скачайте tar.xz с этой версией , вычислите его sha256sum, впишите в PKG_HASH
-
-1 раз где-нибудь пропатчите файлы последней версии wireguard в текстовом редакторе, скопируйте в build_dir,
-сделайте версию для openwrt. эти же файлы скопируйте на ваш сервер с десктопным linux, сделайте там make / make install
-
-Но имейте в виду, что build_dir - локация для временных файлов.
-make clean оттуда все снесет, включая ваши модификации. Модифицированные файлы лучше сохранить отдельно,
-чтобы потом было легко скопировать обратно.
-
-Полученные ipk копируем на роутер в /tmp, устанавливаем через
-# cd /tmp
-# rm -r /tmp/opkg-lists
-# opkg install *.ipk
-Если требует зависимостей, то
-# opkg update
-# opkg install .... <зависимости>
-# rm -r /tmp/opkg-lists
-# opkg install *.ipk
-
-В /tmp/opkg-lists opkg хранит кэш списка пакетов. Если попытаться установить файл ipk, и такой же пакет
-найдется в репозитории, opkg будет устанавливать из репозитория. А нам это не надо.
-
-# rmmod wireguard
-# kmodloader

-должны увидеть что-то вроде :
-[8985.415490] wireguard: WireGuard 0.0.20190123 loaded. See www.wireguard.com for information.
-[8985.424178] wireguard: Copyright (C) 2015-2019 Jason A. Donenfeld <Jason@zx2c4.com>. All Rights Reserved.
-значит модуль загрузился
-
-Могут понадобиться ключи opkg --force-reinstall, --force-depends.
---force-depends поможет при несоответствии hash версии ядра. То есть версия x.x.x та же самая, но hash конфигурации разный.
-При несоответствии x.x.x вы что-то делаете не так, работать это не будет.
-Например : 4.14.56-1-b1186491495127cc6ff81d29c00a91fc, 4.14.56-1-3f8a21a63974cfb7ee67e41f2d4b805d
-Это свидетельствует о несоответствии .config ядра при сборке прошивки и в SDK.
-Если несоответствие легкое, то может все прокатить, но при более серьезной разнице в .config модуль может не загрузиться
-или вызвать стабильные или хаотические падения ядра и перезагрузки (включая вариант беcконечной перезагрузки - bootloop).
-Так что перед --force-depends убедитесь, что знаете как лечится такая ситуация, и не стоит это делать при отсутствии физического
-доступа к девайсу.
-
-Когда поднимите линк, и вдруг ничего не будет работать, то посмотрите в wireshark udp пакеты
-на порт endpoint. Они не должны начинаться с 0,1,2,3,4. В первых 4 байтах должен быть рандом,
-в следующих 4 байтах - значения из измененного enum message_type. Если пакет все еще начинается с 0..4,
-значит модуль wireguard оригинальный, что-то не собралось, не скопировалось, не перезапустилось.
-В противном случае должен подняться линк, пинги ходить. Значит вы победили, поздравляю.
-Регулятору будет намного сложнее поймать ваш VPN.
