First, the simple question: what's the simplest cross-platform way of implementing scsi_ulto4b and scsi_4btoul (/sys/cam/scsi/scsi_all.h) for 64 bit values. GEOM (/sys/geom/geom_enc.c) implements it via a 64 bit cast in g_enc_le8. Is this the best current way? Second, anyone done work on unifying our various byte ordering macros? Besides htonl and ntohl, there are scsi_*ul*, g_enc_*, openssl/aes_locl.h, machine/endian.h, arpa/nameser.h, and I'm sure there are others. Perhaps the best thing is to add macros similar to geom_enc_* to machine/endian.h. Any ideas?
