This bypasses any issues we might have with containers where IPv6 is

This comes at a minor test-coverage cost: we don't test GDBusServer's
default behaviour when told to listen on "tcp:" or "nonce-tcp:", and
on systems where IPv6 is available, we don't test it. If we want to
do those, we should perhaps do them in separate tests, and disable

Conceptually, a D-Bus server is really trying to determine the credentials
of (the process that initiated) a connection, not the credentials that
the process had when it sent a particular message. Ideally, it does
this with a getsockopt()-style API that queries the credentials of the
connection's initiator without requiring any particular cooperation from
that process, avoiding a class of possible failures.
The leading '\0' in the D-Bus protocol is primarily a workaround
for platforms where the message-based credentials-passing API is
strictly better than the getsockopt()-style API (for example, on
FreeBSD, SCM_CREDS includes a process ID but getpeereid() does not),
or where the getsockopt()-style API does not exist at all. As a result
libdbus, the reference implementation of D-Bus, does not implement
Linux SCM_CREDENTIALS at all - it has no reason to do so, because the
SO_PEERCRED socket option is equally informative.
This change makes GDBusServer on Linux more closely match the behaviour
of libdbus.
In particular, GNOME/glib#1831 indicates that when a libdbus client
connects to a GDBus server, recvmsg() sometimes yields a SCM_CREDENTIALS
message with cmsg_data={pid=0, uid=65534, gid=65534}. I think this is
most likely a race condition in the early steps to connect:
client server
connect
accept
send '\0' <- race -> set SO_PASSCRED = 1
receive '\0'
If the server wins the race:
client server
connect
accept
set SO_PASSCRED = 1
send '\0'
receive '\0'
then everything is fine. However, if the client wins the race:
client server
connect
accept
send '\0'
set SO_PASSCRED = 1
receive '\0'
then the kernel does not record credentials for the message containing
'\0' (because SO_PASSCRED was 0 at the time). However, by the time the
server receives the message, the kernel knows that credentials are
desired. I would have expected the kernel to omit the credentials header
in this case, but it seems that instead, it synthesizes a credentials
structure with a dummy process ID 0, a dummy uid derived from
/proc/sys/kernel/overflowuid and a dummy gid derived from
/proc/sys/kernel/overflowgid.
In an unconfigured GDBusServer, hitting this race condition results in
falling back to DBUS_COOKIE_SHA1 authentication, which in practice usually
succeeds in authenticating the peer's uid. However, we encourage AF_UNIX
servers on Unix platforms to allow only EXTERNAL authentication as a
security-hardening measure, because DBUS_COOKIE_SHA1 relies on a series
of assumptions including a cryptographically strong PRNG and a shared
home directory with no write access by others, which are not necessarily
true for all operating systems and users. EXTERNAL authentication will
fail if the server cannot determine the client's credentials.
In particular, this caused a regression when CVE-2019-14822 was fixed
in ibus, which appears to be resolved by this commit. Qt clients
(which use libdbus) intermittently fail to connect to an ibus server
(which uses GDBusServer), because ibus no longer allows DBUS_COOKIE_SHA1
authentication or non-matching uids.

On Linux, if getsockopt SO_PEERCRED is used on a TCP socket, one
might expect it to fail with an appropriate error like ENOTSUP or
EPROTONOSUPPORT. However, it appears that in fact it succeeds, but
yields a credentials structure with pid 0, uid -1 and gid -1. These
are not real process, user and group IDs that can be allocated to a
real process (pid 0 needs to be reserved to give kill(0) its documented
special semantics, and similarly uid and gid -1 need to be reserved for
setresuid() and setresgid()) so it is not meaningful to signal them to
high-level API users.
An API user with Linux-specific knowledge can still inspect these fields
via g_credentials_get_native() if desired.
Similarly, if SO_PASSCRED is used to receive a SCM_CREDENTIALS message
on a receiving Unix socket, but the sending socket had not enabled
SO_PASSCRED at the time that the message was sent, it is possible
for it to succeed but yield a credentials structure with pid 0, uid
/proc/sys/kernel/overflowuid and gid /proc/sys/kernel/overflowgid. Even
if we were to read those pseudo-files, we cannot distinguish between
the overflow IDs and a real process that legitimately has the same IDs
(typically they are set to 'nobody' and 'nogroup', which can be used
by a real process), so we detect this situation by noticing that
pid == 0, and to save syscalls we do not read the overflow IDs from
/proc at all.
This results in a small API change: g_credentials_is_same_user() now
returns FALSE if we compare two credentials structures that are both
invalid. This seems like reasonable, conservative behaviour: if we cannot
prove that they are the same user, we should assume they are not.

Accordingly, the `DesktopFileDir` objects either have to be

(3) synchronised between the two threads
to avoid one of them being used by one thread after being freed on
another. Option (1) changed with commit 99bc33b6 and is no longer an

When the _g_dbus_worker_flush_sync() schedules the 'data' and releases
the worker->write_lock, it is possible for the GDBus worker thread thread
to finish the D-Bus call and acquire the worker->write_lock before
the _g_dbus_worker_flush_sync() re-acquires it in the if (data != NULL) body.
When that happens, the ostream_flush_cb() increases the worker->write_num_messages_flushed
and then releases the worker->write_lock. The write lock is reacquired by
the _g_dbus_worker_flush_sync(), which sees that the while condition is satisfied,
thus it doesn't enter the loop body and immediately clears the data members and
frees the data structure itself. The ostream_flush_cb() is still ongoing, possibly
inside flush_data_list_complete(), where it accesses the FlushData, which can be
in any stage of being freed.
Instead, add an explicit boolean flag indicating when the flush is truly finished.

g_date_time_add_seconds() and g_date_time_add_full() use floating-point

different floating-point rounding when a value is stored in the 80-bit

Previously, if a method was not annotated with org.gtk.GDBus.C.UnixFD

The gobject introspection comments have a reference to an incorrect
class: they have, as 'self', the GSubprocess class instead of
GSubprocessLauncher.
This patch fixes this.
g_settings_backend_watch() uses a weak notify for keeping track of
the target. There's an explanation why this is supposed to be safe but
that explanation is wrong.
The following could happen before:
1. We have the target stored in the watch list
2. The last reference to the target is dropped in thread A and we end up
in g_settings_backend_watch_weak_notify() right before the mutex
3. g_settings_backend_dispatch_signal() is called from another thread B
and gets the mutex before 2.
4. g_weak_ref_init() is called on the target from thread B, which at
this point has a reference count of exactly one (see g_object_unref()
where it calls the weak notifies)
5. Thread A continues at 3. and drops the last reference and destroys
the object. Now the GWeakRef from 4. points to a destroyed object. Note
that GWeakRefs would be cleared before the weak notifies are called
6. At some later point another thread g_weak_ref_get() is called by
g_settings_backend_invoke_closure() and accesses an already destroyed
object with refcount 0 from the GWeakRef created in 4. by thread B (or
worse, already freed memory that was reused).
Solve this by actually storing a GWeakRef of the target in the watch
list and only access the target behind it via the GWeakRef API, and then
pass a strong reference to the notification dispatch code.
The weak notify is only used to remove the (potentially with empty
GWeakRef) target from the list of watches and the only place that
compares the target by pointer instead of going through the GWeakRef
API.

Meson 0.50, but we haven't bumped the minimum version of Meson we
require, yet; which means we're getting compatibility warnings when
using recent versions of Meson, and undefined behaviour when using older
versions.
The configure_file() object defaults to `install: false`, unless an
install directory is used. This means that all instances of an `install`
argument with an explicit `true` or `false` value can be removed,
whereas all instances of `install` with a value determined from a
configuration option must be turned into an explicit conditional.
