etaHEN Plugin SDK

• The etaHEN Plugin SDK is a collection of tool open source tools and samples for developing for etaHEN, requires the Johns SDK
• The etaHEN Plugin SDK has support for dynamic linking with libraries available in the libs folder
• Any ELF or Plugin made with this SDK is already jailbroken, no code required

Note

Kstuff slows down plugin loading! If you are on a firmware that uses kstuff it may take up to 1 min for the plugin to load

ELFs vs etaHEN Plugins

• ELFs: are meant for single use payload-like programs where they run a single task (like showing hwinfo in a notification, etc) will need johns elf losder active
• Plugins: are daemons that are meant to run the whole time the console is on in the background (can only be loaded by etaHEN)

Plugins

• Plugins can be loaded by etaHEN automatically from either /mnt/usb<number>/etaHEN/plugins or internally from /data/etaHEN/plugins when etaHEN is first ran or by the etaHEN toolbox
• Plugins located in the etahen > plugins folder on USB root are given priority over internally installed plugins in /data/etaHEN/plugins
• Duplicate Plugins are ignored by etaHEN on startup (but are listed in the toolbox's plugin section), etaHEN also checks if the plugin title id is already running
• Plugins can be killed and ran via etaHEN's toolbox
• each plugin has its own title id and version defined in the plugins CMakeLists.txt file as follows

set(PLUGIN_TITLE_ID "TEST00000")
set(PLUGIN_VERSION "9.99")

• libhijacker provides plugins with tools to modify processes

static void default_handler(int sig) {
    (void) sig;
    kill(getpid(), SIGKILL);
}
