LinkedIn YouTube Facebook Twitter Products If you’re looking for assistance, Red Hat Consulting Services can share their expertise and guidance to help you get there, and possibly save you time and money in the process. Need help? Red Hat Consulting Services has assisted many customers with their Red Hat Enterprise Linux upgrade projects. If you need more time to upgrade before the EOM date, Red Hat is announcing a one-time, 4 year Extended Lifecycle Support (ELS) maintenance period for Red Hat Enterprise Linux 7. You can also work with Red Hat’s expert consulting services for a fully-automated upgrade process. However, you can perform an in-place upgrade from Red Hat Enterprise Linux 7 to Red Hat Enterprise Linux 8 and then perform a second in-place upgrade to Red Hat Enterprise Linux 9 when you’re ready. It is not possible to perform an in-place upgrade directly from Red Hat Enterprise Linux 7 to Red Hat Enterprise Linux 9. Red Hat Enterprise Linux 9.3 and 8.9 add new features and capabilities for container management and automation, helping enhance containerized innovations across the hybrid cloud. Retain your system’s configurations, subscriptions, and applications, and run a leapp pre-upgrade analysis report to identify upgradability issues and automate remediations where possible to reduce manual intervention. Included with your subscription, leapp simplifies the upgrade in less time and with less effort than traditional redeployment projects by delivering a single, automatable path to upgrade to the next major version of Red Hat Enterprise Linux. As a result, deadlocks in libdb no longer occur in the described scenario.Leapp is the supported tool used to perform in-place system upgrades from Red Hat Enterprise Linux 7 to 8 without having to reinstall your systems. With this update, the btree version of the cursor->get method has been modified to lock the tree's pages in the same order as the writing methods, that is, the primary tree first and the OPD tree second. This consequently caused a deadlock in libdb because neither of the processes released their locks. When a writer process accessed a page from the primary tree while a reader process accessed a page from the OPD tree, the processes were unable to access the page from the other tree because the pages were simultaneously locked by the other process. A writer process accessed first the primary tree and then the OPD tree while a reader process did the same in the reverse order. Previously, the libdb database did not lock its internal buffers in the correct order when it accessed pages located in an off-page duplicate (OPD) tree while processing operations on a cursor. (BZ#1419761)Ĭertificate System now uses the Mozilla NSS secure random number generator Note that by default, the allowSameKeyRenewal parameter is set to true in the UniqueKe圜onstraint. Additionally, the caFullCMCUserSignedCert.cfg profile has been updated to contain both the UniqueKe圜onstraint and the RenewGracePeriodConstraint, which must be placed in the correct order. If there is an existing origNotAfter attribute, it is not overwritten in this process in order to not interfere with the existing renewal by serial flow. Additionally, it preserves the origNotAfter attribute of the most recent certificate that shares the same key in the request, which allows the attribute to be used by the RenewGracePeriodConstraint. The implementation uses the caFullCMCUserSignedCert with the UniqueKe圜onstraint enhanced profile constraint, which has also been updated to disallow renewal of a key shared by a revoked certificate. This update enables the Certificate Authority (CA) to process Certificate Management over CMS (CMC) renewal requests signed by a previously issued signing certificate.
