Announcing dbus 1.15.6 (development release)

[Simon McVittie]

dbus is the reference implementation of D-Bus, a message bus for
communication between applications and system services.

This is a development release for early adopters. If in doubt, please
use dbus 1.14.x instead, especially in stable OS distributions.

git tag: dbus-1.15.6

Denial-of-service fixes:

• Fix an assertion failure in dbus-daemon when a privileged Monitoring
  connection (dbus-monitor, busctl monitor, gdbus monitor or similar)
  is active, and a message from the bus driver cannot be delivered to a
  client connection due to <deny> rules or outgoing message quota. This
  is a denial of service if triggered maliciously by a local attacker.
  (dbus#457; hongjinghao, Simon McVittie)

Enhancements:

• Special-case reading pseudo-files from Linux /proc to take into
  account the filesystem's unusual semantics (dbus!401, Luca Boccassi)

Other fixes:

• Fix compilation on compilers not supporting __FUNCTION__
  (dbus!404, Barnabás Pőcze)

• Fix some memory leaks on out-of-memory conditions
  (dbus!403, Barnabás Pőcze)

• Documentation:
  · Update the README to recommend building with Meson
    (dbus!402, Ahmed Abdelfattah)
  · Fix syntax of a code sample in dbus-api-design
    (dbus!396; Yen-Chin, Lee)

• CMake build fixes:
  · Detect presence of <sys/syscall.h> (dbus!400, Luca Boccassi)

Tests and CI enhancements:

• Fix CI pipelines after freedesktop/freedesktop#540
  (dbus!405, dbus#456; Simon McVittie)

• Ensure the messagebus user is created if necessary
  (dbus#445, Ralf Habacker)
