9.1.0 ^^^^^
Known Issues ************
* When using a distribution with a recent SELinux release such as CentOS 8 Stream, PING health-monitor does not work as shell_exec_t calls are denied by SELinux.
* Fixed configuration issue which allowed authenticated and authorized users to inject code into HAProxy configuration using API requests. Octavia API no longer accepts unencoded whitespace characters in url_path values in update requests for healthmonitors.
Upgrade Notes *************
* The fix that updates the Netfilter Conntrack Sysfs variables requires rebuilding the amphora image in order to be effective.
Bug Fixes *********
* Increased the TCP buffer memory maximum and enabled MTU ICMP black hole detection.
* The generated RSyslog configuration on the amphora supports now RSyslog failover with TCP if multiple RSyslog servers were specified.
* In order to avoid hitting the Neutron API hard when batch update with creating many new members, we cache the subnet validation results in batch update members API call. We also change to validate new members only during batch update members since subnet ID is immutable.
* Ensure that the provided rsyslog configuration file is used by the rsyslog by restarting the service, it fixes the log offloading feature on distributions that start rsyslog before cloud-init.
* Ensure that the provided rsyslog configuration file is used by rsyslog in the amphora by restarting the service when using the amphorav1 provider, it fixes the log offloading feature on distributions that start rsyslog before cloud-init.
* Fixed issues when building amphora image for Centos Stream 9.
* Fixed issues when building amphora image for RHEL 9.
* Fix an authentication error with Barbican when creating a TERMINATED_HTTPS listener with application credential tokens or trust IDs.
* Correctly detect the member operating status "drain" when querying status data from HAProxy.
* Fix the shutdown of the driver-agent, the process might have been stuck while waiting for threads to finish. Systemd would have killed the process after a timeout, but some children processes might have leaked on the controllers.
* Enable required SELinux booleans for CentOS or RHEL amphora image.
* Fixed backwards compatibility issue with the feature that preserves HAProxy server states between reloads. HAProxy version 1.5 or below do not support this feature, so Octavia will not to activate it on amphorae with those versions.
* Fix a bug that prevented the provisioning_state of a health- monitor to be set to ERROR when an error occurred while creating, updating or deleting a health-monitor.
* Fix an issue with IPv6 members that could have been set in operating_status "ERROR" just after being added.
* Fix an issue with amphorav2 and persistence, some long tasks executed by a controller might have been released in taskflow and rescheduled on another controller. Octavia now ensures that a task is never released early by using a keepalive mechanism to notify taskflow (and its redis backend) that a job is still running.
* Fixed an issue with members in ERROR operating status that may have been updated briefly to ONLINE during a Load Balancer configuration change.
* Netfilter Conntrack Sysfs variables net.netfilter.nf_conntrack_max and nf_conntrack_expect_max get set to sensible values on the amphora now. Previously, kernel default values were used which were much too low for the configured net.netfilter.nf_conntrack_buckets value. As a result packets could get dropped because the conntrack table got filled too quickly. Note that this affects only UDP and SCTP protocol listeners. Connection tracking is disabled for TCP- based connections on the amphora including HTTP(S).
* Fix a bug when adding a member on a subnet that belongs to a network with multiple subnets, an incorrect subnet may have been plugged in the amphora.
* Fix a bug when deleting the last member plugged on a network, the port that was no longer used was not deleted.
* Fix a bug when updating a load balancer with a QoS policy after a failover, Octavia attempted to update the VRRP ports of the deleted amphorae, moving the provisioning status of the load balancer to ERROR.
* Fix a potential race condition when updating a resource in the amphorav2 worker. The worker was not waiting for the resource to be set to PENDING_UPDATE, so the resource may have been updated with old data from the database, resulting in a no-op update.
* Fixed issue with SELinux and the lvs-masquerade.sh script on the amphora. The script already runs with root permissions, so the use of sudo inside the script is unneeded.
* Fix an issue when Octavia performs a failover of an ACTIVE-STANDBY load balancer that has both amphorae missing. Some tasks in the controller took too much time to timeout because the timeout value defined in "[haproxy_amphora].active_connection_max_retries" and "[haproxy_amphora].active_connection_rety_interval" was not used.
* Fix a bug that could have triggered a race condition when configuring a member interface in the amphora. Due to a race condition, a network interface might have been deleted from the amphora, leading to a loss of connectivity.
* Fixed "Could not retrieve certificate" error when updating/deleting the client_ca_tls_container_ref field of a listener after a CA/CRL was deleted.
* Fixed validations in L7 rule and session cookie APIs in order to prevent authenticated and authorized users to inject code into HAProxy configuration. CR and LF (\r and \n) are no longer allowed in L7 rule keys and values. The session persistence cookie names must follow the rules described in https://developer.mozilla.org/en- US/docs/Web/HTTP/Headers/Set-Cookie.
* Fix load balancers stuck in PENDING_UPDATE issues for some API calls (POST /l7rule, PUT /pool) when a provider denied the call.
* Validate that the creation of L7 policies is compatible with the protocol of the listener in the Amphora driver. L7 policies are allowed for Terminated HTTPS or HTTP protocol listeners, but not for HTTPS, TCP or UDP protocols listeners.
Other Notes ***********
* The string representation of data base model objects has been improved. Calling str() on them will return a certain subset of fields and calling repr() on them will return all fields. This is helpful for debugging, but it may also change some of the log messages that Octavia emits.
