Превращаем роутер в iSCSI target

[sakatgg]

Dioptimize Ок, большое спасибо собралось на AA с этим патчем нормально.

P.S.

ПОПРАВИЛ ПАТЧ!

Поледний вариант - вылетает. Первый (в папке 1) был рабочий.

[свернуть]

На всякий случай приложил оба варианта, мож что не так скопировалось.

P.S.2 Еще проблема на АА с luci-app-scst, скинул в /package, но в make menuconfig не появилось. На Openwrt 18.06.4 появляется нормально.

Вопрос: при включении на АА DIRECT_IO + патч 900-scst-exec-req-fifo-3.3.patch - достаточно сделать make clean? Или по новой с make distclean пересобирать?

Вопрос2 Сейчас лежит исходник /dl/scst-3.3.x-r8498.tar.bz2. Можно как-то в makefile отключить проверку новых ревизий, а то при каждом разе лезет проверять обновление. Инет не всегда есть.

luci-app-scst для новой версии Luci-Web интерфейса, в AA старая версия.

Не уверен, что он адекватно применился для этого ядра, там нужна скорее всего ручная правка.
Например строки:

--- old/block/blk-map.c	2012-03-19 23:46:01 +0000
+++ new/block/blk-map.c	2012-03-20 00:10:37 +0000

Должны быть такие:

--- a/block/blk-map.c
+++ b/block/blk-map.c

(и так далее, для всех подобных строк, дату и время можно удалить)
DIRECT_IO уже писать не нужно, его нету в конфигурации ядра, достаточно применить вышеупомянутый патч.

Посмотреть применился ли патч, можно зайдя по пути:
openwrt\build_dir\target-<платформа>_musl\linux-<платформа>\linux-<версия ядра>\block\blk-map.c
И сравнить со строками в патче, где "+" это должны были добавится эти строки в blk-map.c файл, а "-" удалится.

Удалите из Makefile переменную SVN_REVISION.
Было:

SVN_REVISION=r$(shell svn info $(PKG_SOURCE_URL)|grep Revision|cut -f2 -d\ )
PKG_SOURCE_SUBDIR:=$(PKG_NAME)-$(PKG_VERSION)-$(SVN_REVISION)

Стало:
