This doesn't work for me AT ALL. I get an oops early during boot (in "systemd-cryptse.." - it happens immediately after typing in my disk encryption key so it's possible/likely that you need an md-crypt setup to see this). It's a NULL pointer derefernce (at offset 0x18) where the callchain looks like this: RIP: skcipher_recvmsg+0x360/0x410 Call Trace: sock_read_iter+0xd0/0x120 new_sync_read+0x79/0xb0 __vfs_read+0x13/0x50 SyS_read+0x41/0x0b0 system_call_fastpath which I assume is related to the iov_iter conversion. That oops then is followed immediately by another that is a NULL pointer dereference in skcipher_sock_destruct, but the callchain for that is just the exit as part of killing of the original oops, so that second oops seems to be just a result of the first one. I'm assuming the culrpit is 1d10eb2f156f ("crypto: switch af_alg_make_sg() to iov_iter") but haven't tested. Sorry for the lack of full dmesg, but the oops happens before the system is actually usable, so I just have a camera screenshot of it. Any ideas?
