Failed to login iscsi target

I am using the latest targetcli-fb and configure the iscsi target in Arch Linux. Everything is fine but when I try to run discovery on another server (Debian and Windows) it failed.

From journald it shows:

kernel: iSCSI Login negotiation failed.
kernel: iscsi_login_setup_crypto() failed
kernel: crypto_alloc_hash() failed for conn_rx_tfm
kernel: iSCSI Login negotiation failed.

and the targetcli configs:
/iscsi> ls
o- iscsi .............................................................................................................. [Targets: 1]
  o- iqn.2003-01.org.linux-iscsi.xxx.x8664:sn.729471705929 .............................................................. [TPGs: 1]
    o- tpg1 ................................................................................................. [no-gen-acls, no-auth]

Re: Failed to login iscsi target

Please use code tags for your config and other terminal output for better readability. Still, it looks ok to me.

I have targetcli-fb on one of my Arch boxes, but it's an old version (2.1.fb35-1) built back in June (official packages are up to date). Discovery and login from another Arch box works. I don't have time to troubleshoot further, but if you haven't found a solution by Monday I can update and maybe be of more use.

Re: Failed to login iscsi target

Found out what's going wrong. It's because the module "crc32c" is not loaded. I run the command "modprobe crc32c" and everything is fine.

Just don't know why the module is not loaded by default, I can't found any clues so I manually put a crc32c.conf at /etc/modules-load.d/

Re: Failed to login iscsi target

That's strange. In my case crc32c_generic is loaded automatically when I run discovery from another Arch machine.
