OpenBGPD 9.1 released

OpenBGPD 9.1 has been released, which will be arriving in the

OpenBGPD directory of your local OpenBSD mirror soon.

This release includes the following changes to the previous release:

• Improve outbound filter performance by storing the rules in an array and also deduplicate equal filters across peers. This and the filter_set change reduce the initial sync duration of large route servers by more than 25%.

  
  

• Improve performance of filter_sets processing in the RDE process by moving to a linear array of set objects to reduce cache misses.

  
  

• Add better logging for attribute parse errors which cause a session reset via UPDATE ATTRLIST error notification.

  
  

• Introduce various additional memory metrics which are part of the 'show rib memory' command. Some values are also tracked per-neighbor and visible via 'show neighbor'.

  
  

• Fix logic error when handling per-peer and per-group MRT message dump configurations.

  
  

OpenBGPD-portable is known to compile and run on FreeBSD and the Linux distributions Alpine, Debian, Fedora, RHEL/CentOS and Ubuntu.
