Steve, find two patches that replaces the previous ones. One patch removes all authentication mechs for SMB1 that are NTLM or less secure but leaves SMB1 with ActiveDirectory KRB5 and NTLMSSP support. Second patch forks the ARC4 code in the kernel and creates a new kernel module under fs/cifs_common that contains the ARC4 crypto that cifs/ ksmbd and also all other kernel subsystems that need ARC4 support can use.
