Subject: [PATCH AUTOSEL 5.19 15/38] ksmbd: return STATUS_BAD_NETWORK_NAME error status if share is not configured

From: Namjae Jeon <linkinjeon@...nel.org>

[ Upstream commit fe54833dc8d97ef387e86f7c80537d51c503ca75 ]

If share is not configured in smb.conf, smb2 tree connect should return
STATUS_BAD_NETWORK_NAME instead of STATUS_BAD_NETWORK_PATH.
