Starting from SBR 8.6.0R2 Release, the following are the features and limitation

 

Features

  1. Before installing Signalware on RHEL 7.5, you must disable kernel address space layout randomization (KASLR), which is enabled by default on RHEL 7.5. Signalware is incompatible with KASLR and requires the kernel memory address space to be consistent.

  2. To disable KASLR:

    1. Edit the GRUB_CMDLINE_LINUX key in the /etc/default/grub file to add the new parameter nokaslr. Example: GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=rhel_bng-lnx-perf6/root rd.lvm.lv=rhel_bng-lnx-perf6/swap rhgb quiet nokaslr".
    2. Run grub2-mkconfig -o /boot/grub2/grub.cfg.
    3. Reboot the server.

      This disables the KASLR feature on Linux Kernel.

    4. Install Signalware.
    5. Start Signalware.
  3. To know more about KASLR, refer to the RHEL 7.5 kernel release notes.

Limitation

  1. SBR does not log the Grouped AVP's like Vendor-Specific-Application-ID in Diameter Message due to design constraint.
