            Bug ID: 3575
           Summary: wrong usage message: "-Q protocol_feature" is an
                    invalid query type
           Product: Portable OpenSSH
           Version: 9.2p1
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: minor
          Priority: P5
         Component: sftp-server
          Assignee: unassigned-bugs at mindrot.org
          Reporter: max at mx17.net

When running the executable /usr/lib/openssh/sftp-server, there is an
issue with the displayed message of the usage parameter "-Q".

    # /usr/lib/openssh/sftp-server -h
    usage: sftp-server [-ehR] [-d start_directory] [-f log_facility]
[-l log_level]
            [-P denied_requests] [-p allowed_requests] [-u umask]
           sftp-server -Q protocol_feature
    # /usr/lib/openssh/sftp-server -Q protocol_feature
    Invalid query type

I think "-Q" supports only "requests":

        case 'Q':
            if (strcasecmp(optarg, "requests") != 0) {
                fprintf(stderr, "Invalid query type\n");
                exit(1);
            }

The incorrect usage parameter in the executable's message can cause
confusion and frustration for users trying to utilize the tool.
Please let me know if you need any further information or
clarification.

Thank you for your time.

Max
