Subject: Disable key exchange if ARC4 is not available
Date: Wed, 18 Aug 2021 14:10:20 +1000	[thread overview]
Message-ID: <20210818041021.1210797-1-lsahlber@redhat.com> (raw)

Steve,

We depend on ARC4 for generating the encrypted session key in key exchange.
This patch disables the key exchange/encrypted session key for ntlmssp
IF the kernel does not have any ARC4 support.

This allows to build the cifs module even if ARC4 has been removed
though with a weaker type of NTLMSSP support.
