Networking

The following information will be added to future versions of the QNX SDP 8.0 Utilities Reference.

io-sock -m fdt -m phy -m phy_fdt -d cgem [option[,option...]]

mount -T io-sock [-o option[,option...]] fdt
mount -T io-sock [-o option[,option...]] phy
mount -T io-sock [-o option[,option...]] phy_fdt
mount -T io-sock [-o option[,option...]] cgem
                            

The curl library has been updated to version 8.8.0. For more information, refer to https://curl.se/ch/8.8.0.html.

• Before you install this networking update, make sure that you have installed QNX SDP 8.0.1 Kernel Update (Build 388) (if you installed SDP 8.0 after July 09, 2024, this update is included).
• To use previously released QNX SDP 8.0 Board Support Packages with this update, install the update, and then rebuild your BSP by running make clean and make in the $BSP_ROOT_DIR directory. For more information, go to the user’s guide for your BSP.
• If you install an individual networking driver that supports this update, this update and the recent kernel update are installed automatically. However, you'll have to manually update any other networking drivers that you use. If you don't update, a message like this is displayed when you try to load them:

  link_elf_load_file: /stage-osr4/x86_64/lib/dll/devs-em.so stack.requires(65538) > mod.provides(65537)

• This networking update does not support the devs-qwdi_syn_dhd_pcie-version driver, which supports Synaptics DHD PCIE-based WLAN devices. Don't update your QNX SDP 8.0 installation with this update if you are using it.
• Some product packages contain experimental files. To access status information, do one of the following:
  • In the QNX Software Center, right-click a package, choose Properties, then click Package Contents. The status of each file in the package is displayed.
  • Sign in to www.qnx.com. On the right side of the web page, under Product Registration, click QNX Software Center Portal. Use the portal to search using the Build ID that use -i displays. The binary information that is displayed includes the state.
  • Generate a manifest report. For more information, see the Manifest Reports & File Lookup chapter of the myQNX License Manager and QNX Software Center User's Guide.

• This update adds new sysctl variables that in some environments can improve throughput by reducing the number of TCP ACK responses.
• The implementation of Precision Time Protocol (PTP) in QNX OS networking drivers must now use a new PTP driver framework. This framework includes support for 64-bit timestamps. The ptpd2 utility is updated to use the new framework.

• The FreeBSD version that QNX OS networking is based on has been updated to 13.3.

• The new sysctl variable qnx.net.inet.tcp.rfc1323_timestamps allows you to disable (0) or enable (1; the default) TCP timestamps for incoming and outgoing traffic.
• You can now set the parent device (vlandev) of a VLAN interface to be a bridge. This option helps support VLAN and non-VLAN connections between a QNX host and its guest at the same time.
• The sysctl variable qnx.ipv4idrsvd, which determines the minimum value that io-sock can use for IPv4 ID field, now accepts a value up to 32768.
• The status of the following items has changed from experimental to stable:
  • networking driver for the Intel Ethernet Controller I225 (devs-igc.so)
  • strongSwan (version 5.8.2)
  • multicast and Unicast DNS daemon (mdnsd)

Some experimental items are implemented in the packages of the baseline product. This means these items are installed when you install QNX SDP and, hence, there's nothing else you must do to be able to use them. Other experimental items are contained in their own packages that aren't installed when you install QNX SDP. To locate and install these packages so you can use the items they contain, go to the Available tab in QNX Software Center and search for part or all of the package name. Then, click the package in the search results and then the Install button in the bottom right corner.
