This downgrades errors from setting file attributes via tmpfiles to
warnings and makes them non-fatal.

Also, as a special case, if a file system does not support file
attributes at all, then the message is downgraded to debug, so that it
is not seen at all.

With this change reiserfs should not see any messages at all anymore
(since it apparently does not implement file attributes at all), but XFS
will still get a warning but no failure. The warning is something the
XFS kernel folks should fix though, by adjusting their file attributes
behaviour to be identical to ext234's.

logind: prefer new sessions over older ones on VT switches

Our seat->positions[] array keeps track of the 'preferred' session on a
VT. The only situation this is used, is to select the session to activate
when a VT is activated. In the normal case, there's only one session per
VT so the selection is trivial.

Older greeters, however, implement take-overs when they start sessions on
the same VT that the greeter ran on. We recently limited such take-overs
to VTs where a greeter is running on, to force people to never share VTs
in new code that is written.

For legacy reasons, we need to be compatible to old greeters, though.
Hence, we allow those greeters to implement take-over. In such take-overs,
however, we should really make sure that the new sessions gets preferred
over the old one under all circumstances. Hence, make sure we override
the previous preferred session with a new session.

9 years agosd-bus: fix gvariant structure encoding
David Herrmann [Thu, 16 Jul 2015 09:00:55 +0000 (11:00 +0200)]
sd-bus: fix gvariant structure encoding

In gvariant, all fixed-size objects need to be sized a multiple of their
alignment. If a structure has only fixed-size members, it is required to
be fixed size itself. If you imagine a structure like (ty), you have an
8-byte member followed by an 1-byte member. Hence, the overall inner-size
is 9. The alignment of the object is 8, though. Therefore, the specs
mandates final padding after fixed-size structures, to make sure it's
sized a multiple of its alignment (=> 16).

On the gvariant decoder side, we already account for this in
bus_gvariant_get_size(), as we apply overall padding to the size of the
structure. Therefore, our decoder correctly skips such final padding when
parsing fixed-size structure.

On the gvariant encoder side, however, we don't account for this final
padding. This patch fixes the structure and dict-entry encoders to
properly place such padding at the end of non-uniform fixed-size
structures.

The problem can be easily seen by running:
    $ busctl --user monitor
and
    $ busctl call --user org.freedesktop.systemd1 / org.foobar foobar "(ty)" 777 8

The monitor will fail to parse the message and print an error. With this
patch applied, everything works fine again.

This patch also adds a bunch of test-cases to force non-uniform
structures with non-pre-aligned positions.

Thanks to Jan Alexander Steffens <jan.steffens@gmail.com> for spotting
this and narrowing it down to non-uniform gvariant structures. Fixes #597.
