    - Networking
      The High-Performance Networking Stack (io-sock) was introduced for QNX SDP 7.1 as a replacement for the io-pkt networking stack and is updated for QNX SDP 8.0.
      - Modifying a BSP to support io-sock
        If QNX does not provide a BSP that supports io-sock for your target hardware, you need to create one. To simplify the process, QNX recommends that you start with the io-sock-compatible BSP provided by QNX that most closely matches your target's specifications.
      - Migrating from QNX SDP 7.1 io-pkt to QNX SDP 8.0 io-sock
        Applications that use io-pkt can be modified to use io-sock. QNX recommends the following initial modifications to make them compatible.
      - Migrating from QNX SDP 7.1 io-sock to QNX SDP 8.0 io-sock
      - Migrating io-sock networking drivers with PTP to QNX SDP 8.0.1 io-sock

  - Migrating from SDP 8.0.x to 8.0.2
    Some migration steps that apply to migrating to SDP 8.0 from an earlier environment also apply to moving to SDP 8.0.2 from SDP 8 or SDP 8.0.1.

QNX SDP8.0Migrating to QNX OS 8.0Developer

If your system controls permissions for networking operations using process manager (procmgr) abilities that are set using procmgr_ability(), QNX recommends that you instead generate and apply a security policy that controls abilities (for information, go to the Security Policies chapter of the QNX OS System Security guide). This method helps ensure that io-sock and client processes have the abilities they need to perform networking operations.

If you do not use a security policy, to control io-sock abilities, QNX recommends that you use the sysctl variable qnx.sec.droproot to run io-sock with the abilities for a specified user (for more information, go to the sysctl entry in the QNX OS Utilities Reference).
