Issue #2789 has been updated by garytivey512.


Loaded the cryptodev.ko module as suggested by Sepherosa, and Tcplay works just fine.

Perhaps a note somewhere in the documentation would be useful,... or possibly find a way to load the module (cryptodev.ko) on demand if that is possible/practical.

While trying to create an encrypted container using tcplay I got this error message.
If anyone can help out on this one, it would be appreciated!

container(file) is zeroed-out and mounted using vnconfig vn0 imagefile

kldstat shows dm.ko and dm_target_crypt.ko loaded, but crypto.ko is not loaded --- if I try to manually load crypto.ko the returned message is "interface crypto.1 already present in the KLD 'kernel'!"
