From: Niko Mauno Date: Tue, 1 Apr 2025 14:04:25 +0000 (+0000) Subject: default-providers: Add VIRTUAL-RUNTIME_dbus variable X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=81fd917ac05be19d8345fff272a2ffc17a257880;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git default-providers: Add VIRTUAL-RUNTIME_dbus variable The purpose of the new variable is to facilitate oe-core users who wish to use an alternative runtime D-Bus implementation instead of the default Freedesktop.org's dbus, such as dbus-broker, a recipe for which is currently available under meta-openembedded/meta-oe/recipes-core/dbus/ While introducing this facilitation the intent is to preserve the existing functionality, while allowing the user to optionally select an alternative runtime D-Bus implementation by adding the following line e.g. to local.conf file: VIRTUAL-RUNTIME_dbus = "dbus-broker" As a background, for example the Fedora distribution uses dbus-broker instead of Freedesktop.org's D-Bus implementation. The following excerpts from https://fedoraproject.org/wiki/Changes/DbusBrokerAsTheDefaultDbusImplementation provide background for their technological decision This change provides a more scalable and more reliable implementation in place of the reference implementation. The reference implementation suffers from long-standing issues including potential dead-locks and susceptibility to denial of service attacks, which the replacement implementation does not. and No visible changes in behavior are expected, except for different log messages. Any visibly different behavior to `dbus-daemon` should be reported as a regression. Ideally, this change should only improve the performance and security of the message bus.
