Subject: [PATCH] Handling collision between standard i/o file descriptors and
newly created ones
Though unlikely to happen, it may happen that newly created file
descriptor take the value 0 (stdin), 1 (stdout) or 2 (stderr) if one
of the standard ones have been dismissed in between. So, it may
confuse the program if it is unaware of this change.
The point of this patch is to avoid a reasign of standard file
descriptors on newly created ones.
Closes issue #16

Subject: [PATCH] garray: Fix integer overflows in element capacity
calculations
Integer overflows in size calculations of buffers (GArray and GPtrArray)
allow subsequent buffer overflows. This happens due to conversions
between gsize and guint.
Proof of concept demonstrations of the overflows can be found in issue
2578. They are not being added as unit tests as they require too much
memory to test.
This will affect `GArray`s which are 4GB in size, or `GPtrArray`s which
are 48GB in size.
Fixes: #2578

Subject: [PATCH] gdbusconnection: Fix race between method calls and object
unregistration
If `g_dbus_connection_unregister_object()` (or `unregister_subtree()`)
was called from one thread, while an idle callback for a method call (or
a property get or set) was being invoked in another, it was possible for
the two to race after the idle callback had checked that the
object/subtree was registered, but before it had finished dereferencing
all the data related to that object/subtree.
Unregistering the object/subtree would immediately free the data,
leading the idle callback to cause a use-after-free error.
Fix that by giving the idle callback a strong reference to the data from
inside the locked section where it checks whether the object/subtree is
still registered.

Subject: [PATCH] gdbusconnection: Fix race between subtree method call and
unregistration
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Fix another variant of the previous commit, this time specific to the
idle callback of a method call on a subtree object, racing with
unregistration of that subtree.
In this case, the `process_subtree_vtable_message_in_idle_cb()` idle
callback already has a pointer to the right `ExportedSubtree` struct,
but again doesn鈥檛 have a strong reference to it.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
They are not allowed in the specification, and can lead to infinite
loops when parsing.
That鈥檚 a security issue if your application is accepting D-Bus messages
from untrusted peers (perhaps in a peer-to-peer connection). It鈥檚 not
exploitable when your application is connected to a bus (such as the
system or session buses), as the bus daemons (dbus-daemon or
dbus-broker) filter out such broken messages and don鈥檛 forward them.
Arrays of zero-length elements are disallowed in the D-Bus
specification: https://dbus.freedesktop.org/doc/dbus-specification.html#container-types
oss-fuzz#41428, #41435
Fixes: #2557

Subject: [PATCH] gdbusmethodinvocation: Fix a leak on an early return path
When doing an early return from `g_dbus_method_invocation_return_*()`
due to passing in the wrong type (or no return value when one was
expected), the parameters were not correctly sunk and were leaked.
Fix that. A unit test will be added in a following commit.

Subject: [PATCH] gdbusmethodinvocation: Fix dead code for type checking GetAll
`property_info` is only ever set for `Get` and `Set` calls, not for
`GetAll`, as it only represents a single property. So this code was
never reachable.
Move it out so that it is reachable.

Subject: [PATCH] glocalfileoutputstream: Do not double-close an fd on unlink
error
In case we fail unlinking a file we could close again an FD that has
been already just closed. So avoid this by unsetting it when closing.

Subject: [PATCH] gsocketclient: Fix still-reachable references to cancellables
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
`GSocketClient` chains its internal `GCancellable` objects to ones
provided by the caller in two places using `g_cancellable_connect()`.
However, it never calls `g_cancellable_disconnect()`, instead relying
(incorrectly) on the `GCancellable` provided by the caller being
short-lived.
In the (valid) situation where a caller reuses one `GCancellable` for
multiple socket client calls, or for calls across multiple socket
clients, this will cause the internal `GCancellable` objects from those
`GSocketClient`s to accumulate, with one reference left each (which is
the reference from the `g_cancellable_connect()` closure).
These `GCancellable` instances aren't technically leaked, as they will
all be freed when the caller's `GCancellable` is disposed, but they are
no longer useful and there is no bound on the number of them which will
hang around.
For a program doing a lot of socket operations, this still-reachable
memory usage can become significant.
Fix the problem by adding paired `g_cancellable_disconnect()` calls.
It's not possible to add a unit test as we can't measure still-reachable
memory growth before the end of a unit test when everything has to be
freed.

Subject: [PATCH] gtestdbus: Print the dbus address on a specific FD intead of
stdout
We used to use a pipe for the dbus daemon stdout to read the defined
address, but that was already requiring a workaround to ensure that dbus
daemon children were then able to write to stdout.
However the current implementation is still causing troubles in some
cases in which the daemon is very verbose, leading to hangs when writing
to stdout.
As per this, just don't handle stdout ourself, but use instead a
specific pipe to get the address address. That can now be safely closed
once we've received the data we need.
This reverts commit d80adeaa960ddfa13837900d0391f9bd9c239f78.
Fixes: #2537

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
`_g_get_unix_mount_points()` parses `/etc/fstab` every time it’s called,
so caching the result can improve performance when mounts are queried
frequently.
The cache will remain in memory until `/etc/fstab` is next modified.
This means that the final copy of the cache will be deliberately
‘leaked’ on process exit.

Subject: [PATCH] gutils: Fix g_find_program_in_path() to return an absolute
path
Fix a possibility of returning a relative path, in case PATH contains
a relative path. According to the doc, the function should return an
absolute path.

Subject: [PATCH] gvariant-serialiser: Prevent unbounded recursion in
is_normal()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This fixes a bug in 7c4e6e9fbe473de0401c778c6b0c4aad27d5145a.
The original approach in that commit accidentally only checked the depth
at the leaf nodes in the variant tree, whereas actually the depth should
be checked before recursing to avoid stack overflow.
It neglected to consider that `g_variant_serialised_is_normal()` would
be recursed into by some of the `DISPATCH(_is_normal)` cases. When that
happened, the depth check was after the recursion so couldn鈥檛 prevent a
stack overflow.
Fixes: #2572

Subject: [PATCH] tests/dbus-appinfo: Add test case for flatpak opening an
invalid file
We were testing the case in which we were opening an actual file, and so
potentially using a fd-list, however we were missing the case in which a file
was not existent.
And in such case we are incidentally hitting a leak now.

Subject: [PATCH] xdgmime: fix double free
We free xdg_dirs[i] twice, but fail to free xdg_dirs itself.
Also, since free() is NULL-safe, there is no need for the second check
here.
