smb3: fix setting SecurityFlags when encryption is required

2024-08-08T16:14:53+00:00

Setting encryption as required in security flags was broken. For example (to require all mounts to be encrypted by setting): "echo 0x400c5 > /proc/fs/cifs/SecurityFlags" Would return "Invalid argument" and log "Unsupported security flags" This patch fixes that (e.g. allowing overriding the default for SecurityFlags 0x00c5, including 0x40000 to require seal, ie SMB3.1.1 encryption) so now that works and forces encryption on subsequent mounts.

cifs: fix setting SecurityFlags to true

2024-07-13T14:24:27+00:00

If you try to set /proc/fs/cifs/SecurityFlags to 1 it will set them to CIFSSEC_MUST_NTLMV2 which no longer is relevant (the less secure ones like lanman have been removed from cifs.ko) and is also missing some flags (like for signing and encryption) and can even cause mount to fail, so change this to set it to Kerberos in this case. Also change the description of the SecurityFlags to remove mention of flags which are no longer supported. Cc: stable@vger.kernel.org Reviewed-by: Shyam Prasad N Signed-off-by: Steve French
