[Pkg-pulseaudio-devel] Bug#489060: warning: `pulseaudio' uses 32-bit capabilities (legacy support in use)

[Ted Percival]

Package: pulseaudio
Version: 0.9.10-2
Severity: normal
Tags: patch

On recent Linux kernels (2.6.24? definitely 2.6.25), the kernel logs a
warning about pulseaudio using 32-bit capabilities. This is because it
links with libcap1, but needs to be updated to libcap2 for 64-bit
capability support.

Linux only logs a warning about 32-bit capabilities for the first
process that uses them, so you might not see the message for pulseaudio
if another app triggers the warning first (eg. avahi-daemon, Debian bug
#464712).

You need a versioned dependency on libcap2-dev >= 2.10-1 as described in
the header of the attached patch.

    Build against libcap2
    
    Removes a warning about deprecated 32-bit capabilities.
    Build-Depends on libcap2-dev (>= 2.10-1) to avoid possibly-insecure
    use of v2 capabilities. See kernel/capability.c in the Linux source
    for details (look for warn_deprecated_v2).
