One can only bzero the initial version that existed in illumos. In 52 * other words, if someone passes an older library handle that doesn't support a 53 * version you cannot assume that their structures have those additional members 54 * in them. Instead, a 'base' version is introduced for such types that have 55 * differences and instead we only bzero out the base version and then handle 56 * the additional members. In general, because all additional members will be 57 * assigned, there's no reason to zero them out unless they are arrays that 58 * won't be entirely filled in. 59 * 60 * Due to history, anything added after the update from version 2.4, in other 61 * words additions from or after '5094 Update libsmbios with recent items' 62 * (4e901881) is currently being used for this. While we don't allow software 63 * compiling against this to get an older form, this was the first major update 64 * and a good starting point for us to enforce this behavior which is useful for 65 * moving forward to making this more public. 66 */ 67 68 #include <sys/smbios_impl.h> 69 #include <sys/byteorder.h> 70 #include <sys/debug.h> 71 72 #ifdef _KERNEL 73 #include <sys/sunddi.h> 74 #else 75 #include <fcntl.h> 76 #include <unistd.h> 77 #include <string.h> 78 #endif 79 80 /* 81 * A large number of SMBIOS structures contain a set of common strings used to 82 * describe a h/w component's serial number, manufacturer, etc. These fields 83 * helpfully have different names and offsets and sometimes aren't consistent. 84 * To simplify life for our clients, we factor these common things out into 85 * smbios_info_t, which can be retrieved for any structure.
