One can only bzero the initial version that existed in illumos. In 53 * other words, if someone passes an older library handle that doesn't support a 54 * version you cannot assume that their structures have those additional members 55 * in them. Instead, a 'base' version is introduced for such types that have 56 * differences and instead we only bzero out the base version and then handle 57 * the additional members. In general, because all additional members will be 58 * assigned, there's no reason to zero them out unless they are arrays that 59 * won't be entirely filled in. 60 * 61 * Due to history, anything added after the update from version 2.4, in other 62 * words additions from or after '5094 Update libsmbios with recent items' 63 * (4e901881) is currently being used for this. While we don't allow software 64 * compiling against this to get an older form, this was the first major update 65 * and a good starting point for us to enforce this behavior which is useful for 66 * moving forward to making this more public. 67 */ 68 69 #include <sys/smbios_impl.h> 70 #include <sys/byteorder.h> 71 #include <sys/debug.h> 72 73 #ifdef _KERNEL 74 #include <sys/sunddi.h> 75 #else 76 #include <fcntl.h> 77 #include <unistd.h> 78 #include <string.h> 79 #endif 80 81 #define SMB_CONT_WORD 2 /* contained elements are word size */ 82 83 /* 84 * A large number of SMBIOS structures contain a set of common strings used to 85 * describe a h/w component's serial number, manufacturer, etc. These fields 86 * helpfully have different names and offsets and sometimes aren't consistent. 87 * To simplify life for our clients, we factor these common things out into 88 * smbios_info_t, which can be retrieved for any structure.
