This chapter provides an overview of functionality that has been deprecated in all minor releases of Red Hat Enterprise Linux 7 up to Red Hat Enterprise Linux 7.3.
Deprecated functionality continues to be supported until the end of life of Red Hat Enterprise Linux 7. Deprecated functionality will likely not be supported in future major releases of this product and is not recommended for new deployments. For the most recent list of deprecated functionality within a particular major release, refer to the latest version of release documentation.
Deprecated hardware components are not recommended for new deployments on the current or future major releases. Hardware driver updates are limited to security and critical fixes only. Red Hat recommends replacing this hardware as soon as reasonably feasible.
A package can be deprecated and not recommended for further use. Under certain circumstances, a package can be removed from a product. Product documentation then identifies more recent packages that offer functionality similar, identical, or more advanced to the one deprecated, and provides further recommendations.
nautilus-open-terminal replaced with gnome-terminal-nautilus
Since Red Hat Enterprise Linux 7.3, the nautilus-open-terminal package has been deprecated and replaced with the gnome-terminal-nautilus package. This package provides a Nautilus extension that adds the option to the right-click context menu in Nautilus. nautilus-open-terminal is replaced by gnome-terminal-nautilus during the system upgrade.
sslwrap() removed from Python
function has been removed from Python 2.7
. After the 466 Python Enhancement Proposal
was implemented, using this function resulted in a segmentation fault. The removal is consistent with upstream.
Red Hat recommends using the
ssl.SSLContext class and the
ssl.SSLContext.wrap_socket() function instead. Most applications can simply use the
ssl.create_default_context() function, which creates a context with secure default settings. The default context uses the system's default trust store, too.
Symbols from libraries linked as dependencies no longer resolved by
ld linker resolved any symbols present in any linked library, even if some libraries were linked only implicitly as dependencies of other libraries. This allowed developers to use symbols from the implicitly linked libraries in application code and omit explicitly specifying these libraries for linking.
For security reasons,
ld has been changed to not resolve references to symbols in libraries linked implicitly as dependencies.
As a result, linking with
ld fails when application code attempts to use symbols from libraries not declared for linking and linked only implicitly as dependencies. To use symbols from libraries linked as dependencies, developers must explicitly link against these libraries as well.
To restore the previous behavior of
, use the
command-line option. (BZ#1292230
Windows guest virtual machine support limited
As of Red Hat Enterprise Linux 7, Windows guest virtual machines are supported only under specific subscription programs, such as Advanced Mission Critical (AMC).
libnetlink is deprecated
libnetlink library contained in the iproute-devel package has been deprecated. The user should use the
libmnl libraries instead.
S3 and S4 power management states for KVM are deprecated
Native KVM support for the S3 (suspend to RAM) and S4 (suspend to disk) power management states has been discontinued. This feature was previously available as a Technology Preview.
The Certificate Server plug-in udnPwdDirAuth is discontinued
udnPwdDirAuth authentication plug-in for the Red Hat Certificate Server has been removed in Red Hat Enterprise Linux 7.3. Profiles using the plug-in are no longer supported. Certificates created with a profile using the
udnPwdDirAuth plug-in are still valid if they have been approved.
Red Hat Access plug-in for IdM is discontinued
The Red Hat Access plug-in for Identity Management (IdM) has been removed in Red Hat Enterprise Linux 7.3. During the update, the redhat-access-plugin-ipa package is automatically uninstalled. Features previously provided by the plug-in, such as Knowledgebase access and support case engagement, are still available through the Red Hat Customer Portal. Red Hat recommends to explore alternatives, such as the
The Ipsilon identity provider service for federated single sign-on
The ipsilon packages were introduced as Technology Preview in Red Hat Enterprise Linux 7.2. Ipsilon links authentication providers and applications or utilities to allow for single sign-on (SSO).
Red Hat does not plan to upgrade Ipsilon from Technology Preview to a fully supported feature. The ipsilon packages will be removed from Red Hat Enterprise Linux in a future minor release.
Red Hat has released Red Hat Single Sign-On as a web SSO solution based on the Keycloak community project. Red Hat Single Sign-On provides greater capabilities than Ipsilon and is designated as the standard web SSO solution across the Red Hat product portfolio. For details, see Chapter 1, Overview

Future development on the Linux containers framework is now based on the docker command-line interface. libvirt-lxc tooling may be removed in a future release of Red Hat Enterprise Linux (including Red Hat Enterprise Linux 7) and should not be relied upon for developing custom container management applications.
