mod_docker - handle interface churn.
mod_ovs - retain root privileges to call ovs-vsctl.
mod_dnssd - handle initial failures.

hsflowd

Dell OS10 port now fully operational.

hsflowd

Major reworking of the Linux port. Allows single rpm to be built with dynamic loadable modules for optional features. Supports systemd scheduling. Optional features can be compiled in using the "FEATURES" variable. For example:

  make FEATURES="ULOG NFLOG PCAP DOCKER KVM OVS"

or:

  make -k FEATURES=ALL

See INSTALL.Linux for more details.

hsflowd

Fixed compilation bugs for LIBVIRT and XEN_DDK.
Improved test for setns system call (requires glibc > 2.14 as well as kernel > 3.0.0).

hsflowd

Run counter-polling and packet-sampling in separate threads, so that a blocking call in the polling thread cannot stall the processing of packet samples.

Fix bug introduced in 1.29.0 that reversed sampling direction for Cumulus Linux packet-samples.

Avoid trying to read optical DOM stats from a module that does not support it.

hsflowd

Allow reporting on both containers and VMs at the same time (e.g. "make LIBVIRT=yes DOCKER=yes").

Improve container lifecycle so that containers are removed promptly after they exit.

Eliminate use of /etc/hsflowd.state file for mapping container/VM to sFlow dsIndex. Replaced with hashing scheme.

Reduce counter-polling overhead by refreshing interface counters only when necessary.

hsflowd

This release adds support for packet-sampling via libpcap -- as an alternative to ULOG / NFLOG. If the kernel is new enough then the sampling can be pushed into the kernel to minimize the overhead.

hsflowd

Allow rtmetric and rtflow JSON messages.

hsflowd

v1.28.2

Support Cumulus VX virtual switches.
