Add support for KNX data secure (#66) * initial comic * save work * Handle SystemBroadcast and Broadcast for TP and IP * Rework * Fix comment * save work * save work * save work * save work * save work * Restore old broadcast structure * Readd systembroadcast methods * Make sure that services from SystemBroadcast are also available from Broadcast on closed media * save work * Save work * save work * Save work * save work * save work * save work * save work * save work * Change maximum number of elements for the key tables, etc. * save work * First working seqno sync with ETS * save work * save work * save work * save work * save work * save work * Remove magic value and add comment * save work * Extend restart and masterreset for factory reset * save work * First working secure broadcast mode with IA programming * Add FunctionPropertyExt* AL services * Fix FunctionPropertyExt*. Working T_DATA_CONNECTED with FunctionPropertyExt*. * Add PropertyValueExt* AL services. Handle master reset in AL service RESTART. * Fix FunctionPropertyExtStateRead, fix restart. MILESTONE: Working physical programming of IA and toolkey with confirmed restart. Reading deviceinfos working. * Handle PDT_CONTROL in FunctionPropertyExt* * Fix FunctionPropertyExt* and FunctionProperty for PDT_CONTROL * Change comment. * save work * save work * Add group object security handling * Move map to own file * use simple_map * Include simple_map.h in CmakeFile * Move code from header to source file * Remove obsolete code * MILESTONE: working programming of secure device with IA and tables * cleanup * bugfix * flashSize must be big enough. Security IF object contains a lot more data. * Merge master into feat_datasecure * Revert "Merge master into feat_datasecure" This reverts commit 0c8358692aab13456196dc3a9ce5383bc1a2dec9. * Revert "Revert "Merge master into feat_datasecure"" This reverts commit aa5925378591eb32ea6d89dcb778ab02388a710f. * Bugfixes * cleanup * cleanup * Add printing of uint64_t * Don't compile secapplayer if data secure not enabled * pin platform for ESP8266 to specific version * SecIfObject: save/restore required for persisting STATE. Bugfix: use correct PID for group key table * Cleanup comment and debug output * Further cleanup. * Refactor master reset * Remove unused IP data link layer test code * Only reset TOOL kkey to FDSK on factory reset * Modify .gitignore and remove vscode config file * Correct comment * Handle SBC flag (systembroadcast) in SCF field. Couplers between open and closed media need this. * Remove code that slipped in.
