address changes in the config_t structure on IDA 93

[yeggor]

I tested idalib on the recently released IDA 93 Beta 2 (Version 9.3.260119.bd658ba9).

It was not working due to the changes in the structures related to license checking logic.
The changes were minor, related to config_t (similar to previous update).

As we can see from the pseudocode below, with the changes applied, the logic resolves correctly in libida:

  memset(&qerror, 0, sizeof(qerror));
  license_manager = get_license_manager(v6);
  license_res = license_manager->_vtbl->check_license_params(license_manager, 0, 0);
  if ( license_res && license_res->is_ok )
    goto _exit;
  license_location = get_config()->license_location;
  config0 = get_config();
  license_info = config0->license_info;
  if ( (debug & 0x200) != 0 )
  {
    get_license_str(config0->license_info->lid, &qinfo);
    license = qinfo.n ? qinfo.body : &g_qstring_nullstr;
    callui_msg("Attempting to acquire license: %s\n", license);
    if ( qinfo.body )
    {
      qinfo.n = 0;
      qfree(qinfo.body);
    }
  }
  if ( !license_manager->_vtbl->get_or_borrow_license(license_manager, license_location, license_info, 16, &qerror) )
    goto _exit;
  if ( (g_error_debug & 0xFFFFFFFE) == 2 )
  {
    if ( qerror.n )
      body = qerror.body;
    else
      body = &g_qstring_nullstr;
    result = msg("Failed to retrieve license: %s", body);
    goto _exit_with_err;
  }
  callui(ui_process_action);
  if ( !license_manager->_vtbl->check_license_params(license_manager, 0, 0) )
  {
    result = msg("Cannot continue without a valid license");
_exit_with_err:
    __break(1u);
    return result;
  }

The changes have been tested on macos/linux/windows.

Also, starting with version 9.3, hex-rays provides "armlinux" installers, however libraries are not yet available in releases/9.3.0-beta branch: https://github.com/HexRaysSA/ida-sdk/tree/53900700e45498ccff48edadf6b495c9be2532ae/src/lib. But I verified statically that uint8_t _skip_a[0x2a0]; will work for it (structures are matches between x86-64/AArch64).

@xorpse I've updated the ida-sdk submodule and tested changes with the 9.3.260213.91fc47de released today (macos/windows/linux-x86). We still can't test it with IDA Pro Linux ARM64 9.3 because libraries were not released: https://github.com/HexRaysSA/ida-sdk/tree/d5db59ab4e9d2ae92038e9520082affd0da6fe20/src/lib.

Linking the issue in ida-sdk: HexRaysSA/ida-sdk#32.

I think we can still move to make an initial release--this one would be a new platform anyway, so it's unlikely to affect any current users. I propose to do a quick release with the support we have, then make a follow-up with additional support and #46 once it's ready. After that, we can do a major release with the mutability rework.

Yeah sounds good

Hi, chiming in to ask if you have any plans for an IDA 9.3 compatibility release?

Yes, following HexRaysSA/ida-sdk#32 (comment) well make a release today or tomorrow.
