instead of removing '..' in a given path, call kern_path with LOOKUP_BENEATH flag to prevent the out of share access. ran various test on this: smb2-cat-async smb://127.0.0.1/homes/../out_of_share smb2-cat-async smb://127.0.0.1/homes/foo/../../out_of_share smbclient //127.0.0.1/homes -c "mkdir ../foo2" smbclient //127.0.0.1/homes -c "rename bar ../bar" Cc: Ronnie Sahlberg <ronniesahlberg@gmail.com> Cc: Ralph Boehme <slow@samba.org> Tested-by: Steve French <smfrench@gmail.com> Tested-by: Namjae Jeon <linkinjeon@kernel.org> Acked-by: Namjae Jeon <linkinjeon@kernel.org> Signed-off-by: Hyunchul Lee <hyc.lee@gmail.com> Signed-off-by: Steve French <stfrench@microsoft.com>
