◆ ext_config_dir()

const char * ext_config_dir

(

)

return the abloslute path of external SDI configuration folder directory (VOS: /etc/config/sdi). This folder holds the external configuration files, which were installed by user configuration package to overload SDI default configuration. The external SDI configuration folder contains files for read access only.

Returns: absolute path to external SDI configuration folder (with read-only files)

◆ ext_font_dir()

const char * ext_font_dir

(

)

return the absolute path of the folder for external fonts. (Android: $HOME/fonts/sdi_ext) (VOS: /usr/share/fonts)

This function is un-used on VOS, since fonts are installed with SI font packages to the system folder, we ADK components have access to use them. On Android, ADKPRT runs in context of SDI, therefore, fonts are installed with an user config package to application domain folder.

Returns: absolute path to external fonts directory or an empty string

◆ ext_plugin_dir()

const char * ext_plugin_dir

(

)

return the absolute path of the folder for external plugins (Android: $HOME/plugins).

This folder is used on platforms, which must use a separate folder for plugins. For instance, on Android external plugins come along with plugin update packages and SDI server is not able to write to lib folder (home_lib_dir()) due to missing write permissions. On platforms without external plugins folder (e.g. VOS), this function returns an empty string.

Returns: absolute path to external plugin directory or an empty string

◆ factory_reset()

void factory_reset

(

)

perform a factory reset of SDI server. The function is invoked for command "Factory Reset (20-22)" and does the following:

It removes all writable files, which are modified by SDI server during runtime.
On VOS platforms it synchronizes contents of installed user config packages to restore default configurations files coming along with these packages (see step 3 of init()). On Android user configuration files and SDI plugins are recovered from persitent partition. For this, functions install_user_configuration() and install_sdi_plugins() with flag recover=true are invoked.
It creates writeable files (not belonging to user configuration packages) to restore other default settings, e.g. STATUS.CFG

◆ get_dir_files() [1/2]

int filesystem::get_dir_files	(	const char *	dir,
		std::vector< std::string > *	files = `0`,
		const char *	regex = `0`
	)

helper function to count and/or obtain all files in directory dir. Caller has the option to pass a regular expression regex to match specific files to be considered for the result. The regular expression is applied on the full file path including the path prefix. If no regular expression is passed (NULL), all regular files in the directory are considered. For just counting files of the directory dir, caller can set parameter files to NULL.

Parameters

[in]	dir	path to directory, which contains the files
[out]	files	pointer to vector storing the found files (absolute file paths) or NULL if the function is just used for file counting.
[in]	regex	regular expression to match specific files be considered or NULL to find all regular files in directory `dir`.

Returns: number of files, which were found. -1 is returned in case of error (e.g. from directory path or missing permissions).

The function does not work recursive, thus, subfolders in directory dir are not considered.

◆ get_dir_files() [2/2]

int filesystem::get_dir_files	(	const char *	dir,
		vector< string > *	files,
		const char *	regex
	)

◆ home_config_dir()

(

)

return the abloslute path of SDI configuration folder in home directory (VOS: $HOME/share/sdi). This folder holds the SDI default configuration files, which are used, as long as not overloaded by external user configuration package. SDI configuration folder contains files for read access only.

Returns: absolute path to SDI default configuration folder (with read-only files)

◆ home_config_file() [1/2]

std::string filesystem::home_config_file

(

const std::string &

file

)

Appends a relative filename file to path returned by home_config_dir()

Parameters

[in]

file

relative filename to append to home_config_dir()

Returns: file path

Use this function for SDI configuration file provided by SDI installation packages and which cannot be overloaded by user configuration packages.

◆ home_config_file() [2/2]

string filesystem::home_config_file

(

const string &

file

)

◆ home_flash_dir()

const char * home_flash_dir

(

)

return the absolute path to SDI flash folder in home directory (VOS: $HOME/flash/sdi). If subfolders do not already exist, they are created with the first call of this function. The flash folder is the location for files, which require write access by SDI server. Writeable configuration files are synchononized with those files of external user configuration packages by invocation of init() function at SDI server startup.

Returns: absolute path to SDI flash folder for writeable files

◆ home_flash_file() [1/2]

std::string filesystem::home_flash_file

(

const std::string &

file

)

Appends a relative filename file to path returned by home_flash_dir()

Parameters

[in]

file

relative filename to append to home_flash_dir()

Returns: file path

◆ home_flash_file() [2/2]

string filesystem::home_flash_file

(

const string &

file

)

◆ home_lib_dir()

const char * home_lib_dir

(

)

return the abloslute path of lib folder in home directory (VOS: $HOME/lib).

This library folder is used for SDI plugins and libraries coming along with SDI download packages.

Returns: absolute path to home lib folder

◆ init()

void init

(

)

This function must be called at startup, before SDI server accesses other functions of the filesystem module. The function internally does the following:

It checks the $HOME environment variable. If it is not provided by the system, the function sets $HOME to working directory of SDI server, since this environment variable is referred the most filesystem functions.
It checks for old files of previous SDI server versions and if exist, these files were overtaken to new destination, which is expected by the recent SDI server. Old obsolete files of previous SDI server versions were removed.
On VOS platforms it synchronizes files, which were installed with user configuration packages. Especially those files, which require write access must be overtaken to home flash directory. For this, SDI server holds a registration file with a checksum for each file to detect, if it was overloaded by file of the user configuration package. In addition, after removal of a user configuration package, the associated files are removed again and default files from SDI configuration folder are restored.

◆ install_sdi_plugins()

unsigned short install_sdi_plugins ( bool recover = false )

install SDI plugins from update package, which was added to SDI update directory (see sdi_update_dir()). Plugins are expected in a specified subfolder "plugin". The function is called wiht command "Check for update (20-1D)" using upload type UPLOAD_TYPE_PLUGIN. On Android the update package data is provided and the command is sent by Android Secure Installer. The function copies the external plugin in internal location, which is specified by ext_plugin_dir(). In addition, the function does not allow to install arbitrary files, therefore, it checks, if each found plugin matches the plugin pattern PLUGIN_PATTERN. After the plugins were overtaken to plugin directory, the plugins are loaded and registered for usage in SDI server. If an external plugin has the same name as an internal plugin (provided with SDI base package, see function home_lib_dir()) and shall "overload" it, the internal plugin is unregisted and unloaded before the external plugin installed. Finally, the function stores a backup copy of each plugin to persitent directory (see sdi_persist_dir()) to make the installed plugins recoverable for command "Factory Reset (20-22)". For command "Factory Reset (20-22)" the same function is invoked with flag recover=true, to restore and install the backup copies from persistent directory.

Parameters

[in]

recover

flag set to true to restore and install the SDI plugins from persistent directory

Returns: SDI error code (0x9000 for success, 0x64xx for error)

◆ install_user_configuration()

unsigned short install_user_configuration ( bool recover = false )

install user configuration from update package, which was added to SDI update directory (see sdi_update_dir()). The function is called with command "Check for update (20-1D)" using upload type UPLOAD_TYPE_CONFIG_SDIEMV. On Android the update package data is provided and the command is sent by Android Secure Installer. Configuration files are expected in a specified folder structure, whereas other components than SDI (e.g. ADKEMV or ADKSEC) use a path prefix like "emv" or "sec". The function knows the internal location for each file. In addition, the function does not allow to install arbitrary files, therefore, it checks, if the found files are in internal whitelist (see table allowed_files in filesystem.cpp). After all configuration files were installed the function runs required post actions (if any), which are related to the installed files. Finally, the function stores a backup copy of each file to persitent directory (see sdi_persist_dir()) to make the installed files recoverable for command "Factory Reset (20-22)". For command "Factory Reset (20-22)" the same function is invoked with flag recover=true, to restore and install the backup copies from persistent directory.

Parameters

[in]

recover

flag set to true to restore and install the configuration files from persistent directory

Returns: SDI error code (0x9000 for success, 0x64xx for error)

◆ log_config_dir()

const char * log_config_dir

Required for SW update on Android. On VOS it is unused.

Returns: absolute path to HOME for ADK Logging configuration files

◆ lookup_config_file() [1/2]

std::string filesystem::lookup_config_file

(

const std::string &

file

)

lookup a configuration file (read-only) by its relative path file and return the absolute path for it. The function looks up the file at first in external configuration folder (provided by ext_config_dir()). If not found there, the file is searched in SDI default configuration folder (provided by home_config_dir()). The function return an empty string, if the file is not found in one of both locations.

Parameters

[in]

file

relative file path to look up the configuration file (e.g. "sec/sccfg.json")

Returns: absolute path of the found configuration file (e.g. "/etc/config/sdi/sec/sccfg.json" or "$HOME/sdi/sec/sccfg.json") or an empty string, if the file was not found.

◆ lookup_config_file() [2/2]

		unsigned	modes = `FM_Default`
	)

helper function to remove multiple files. Files to be removed are specified by vector files.

Parameters

[in]	files	vector of files to be removed
[in]	modes	function operation modes, see enum FilesModes

Returns: number of files, which were removed. -1 is returned in case of error due to missing directory or file access.

int filesystem::remove_files	(	const vector< string > &	files,
		unsigned	modes
	)

◆ remove_sdi_plugins()

unsigned short remove_sdi_plugins

(

)

remove SDI plugins according removal file, which is looked up in SDI update directory (see sdi_update_dir()). The removal file is expected in a specified subfolder "plugin". The function is called with command "Check for update (20-1D)" using upload type UPLOAD_TYPE_REMOVE_PLUGIN. On Android the update package data is provided and the command is sent by Android Secure Installer. Before removal of a plugin, the plugin is unloaded and unregistered for usage in SDI server. If a plugin is removed, which has the same name as an internal plugin in home_lib_dir(), the internal plugin is loaded and reactivated again. Finally, the function removes the backup copy of each plugin from persitent directory (see sdi_persist_dir()) so that command "Factory Reset (20-22)" will no longer recover the plugin.

The removal file (remove.json) contains an array 'files' with a filename per plugin to remove. No path prefix is added, the function knows the internal location for each file. The filenames may also contain reguluar expressions to match multiple files to delete. The function does not allow to remove arbitrary files, therefore, it checks, if the regular expression matches one or more plugins is in external plugin folder before the plugin is unregistered, unloaded and removed. If a filename in the removal file does not match any existing plugin, the entry is ignored and it is proceeded with the next one. Example format for removal.json:

{  "files": [    "libsdiplugin.*\.so",  // remove all external SDI plugins  ]}

Returns: SDI error code (0x9000 for success, 0x64xx for error)

◆ remove_user_configuration()

unsigned short remove_user_configuration

(

)

remove user configuration files according removal file, which is looked up in SDI update directory (see sdi_update_dir()). The function is called with command "Check for update (20-1D)" using upload type UPLOAD_TYPE_REMOVE_CONFIG_SDIEMV. On Android the update package data is provided and the command is sent by Android Secure Installer. After removal, it runs required post actions (if any), which are related to the removed files. Finally, the function removes the backup copy of each file from persitent directory (see sdi_persist_dir()) so that command "Factory Reset (20-22)" will no longer recover the files.

The removal file (remove.json) contains an array 'files' with a relative path per file to remove. The same external path representation as in update packages is used and the function knows the internal location for each file. The lines may also contain reguluar expressions to match multiple files to delete. The function does not allow to remove arbitrary files, therefore, it checks, if the found files are in internal whitelist (see table allowed_files). If a line in the removal file does not match any existing allowed file, the line is ignored and it is proceeded with the next line. Example format for removal.json:

{  "files": [    "emv/[Ee][Mm][Vv][_-].*\.[Xx][Mm][Ll]",  // remove all EMV config files    "sec/sccfg.json",    "config.json",    "whitelist.json",    "sensitivetags.json",    "cardranges.json"  ]}

Returns: SDI error code (0x9000 for success, 0x64xx for error)
