X-Git-Url: http://cvs.zerfleddert.de/cgi-bin/gitweb.cgi/proxmark3-svn/commitdiff_plain/463ca973e7cf1e866bb60d7cc33d38e473aa4d3d FIX: hf mf eload - now supports specifying 0,1,2,4 in card memory for the file to be loaded. FIX: hf mf esave - now supports specifying 0,1,2,4 in card memory for the file to be saved. ADD: data.h - added FILE_PATH_SIZE constant ADD: hf legic load - a command help and checks for FILE_PATH_SIZE ADD: hf legis save - now checks for FILE_PATH_SIZE ADD: lf hitag - now checks for FILE_PATH_SIZE ADD: util.c - AddLogLine now checks for FILE_PATH_SIZE ADD: data load / save - now checks for FILE_PATH_SIZE FIX: ui.c - added a case of closing a filehandle FIX: hf mf cload / csave now checks for FILE_PATH_SIZE FIX: armsrc/mifarecmd.c - adjusted the buffersize in MifareEMemget from 48 to USB_CMD_DATA_SIZE --- diff --git a/armsrc/mifarecmd.c b/armsrc/mifarecmd.c index 0d1fb77a..4f3556b2 100644 --- a/armsrc/mifarecmd.c +++ b/armsrc/mifarecmd.c @@ -714,8 +714,8 @@ void MifareNested(uint32_t arg0, uint32_t arg1, uint32_t calibrate, uint8_t *dat crypto1_destroy(pcs);
