The problem might also exists for 3DES-CBC if 3DES hardware crypto is used. If this behavior (incompatibility of "Crypto: hardware" and "Crypto: software" in geom_eli) is known, it shopuld be documented in the geli man page. best regards Stefan Grundmann >How-To-Repeat: seth# mdconfig -a -t malloc -s 8M -u 666 seth# echo -n foobar > /tmp/pass seth# kldunload aesni kldunload: can't find file aesni seth# geli init -J /tmp/pass -i 5 -e AES-XTS -l 256 md666 Metadata backup can be found in /var/backups/md666.eli and can be restored with the following command: # geli restore /var/backups/md666.eli md666 seth# geli attach -j /tmp/pass md666 seth# dd if=/dev/zero of=/dev/md666.eli dd: /dev/md666.eli: end of device 16384+0 records in 16383+0 records out 8388096 bytes transferred in 0.986972 secs (8498818 bytes/sec) seth# dd if=/dev/md666.eli bs=1M | md5 7+1 records in 7+1 records out 8388096 bytes transferred in 0.522124 secs (16065339 bytes/sec) 23a0c69af6b0a448c0372e738ccccbeb seth# geli detach md666 seth# kldload aesni seth# geli attach -j /tmp/pass md666 seth# dd if=/dev/md666.eli bs=1M | md5 7+1 records in 7+1 records out 8388096 bytes transferred in 0.406862 secs (20616562 bytes/sec) a775583473215888a1a02d583b826d50 seth# geli detach md666 seth# seth# kldunload aesni seth# geli attach -j /tmp/pass md666 seth# dd if=/dev/md666.eli bs=1M | md5 7+1 records in 7+1 records out 8388096 bytes transferred in 0.719863 secs (11652348 bytes/sec) 23a0c69af6b0a448c0372e738ccccbeb >Fix: >Release-Note: >Audit-Trail: >Unformatted:
