Package: netatalk
Version: 2.2.5-1
Severity: normal
Tags: patch

Dear Maintainer,

When accessing an AFP server from an old client (using ASP/DDP) with the
default configuration (with atalkd and DDP enabled, of course), no volumes are

 This is because afpd ignores the AppleVolumes.default file and the uservols
for ASP/DDP sessions. It only shows volumes defined in AppleVolumes.system (and
the default configuration has none).

etc/afpd/volume.c's load_volumes function contains a check (line 1962) which
disables AppleVolumes.default loading if the parent_or_child variable indicates
that it's directly running in the main afpd process. This variable is updated
after the fork() in libatalk/dsi/dsi_tcp.c, so the correct volumes are shown
when using AFP over TCP.

The ASP session manager also forks when a new session is created (line 270 of
libatalk/asp/asp_getsess.c) but does not set the parent_or_child variable, so
load_volumes will not load the user-specific volumes nor AppleVolumes.default
on ASP.

The attached patch sets parent_or_child = 1 after this fork(), so clients which
use ASP/DDP will get the correct user-specific volumes.
