|
||||
Subject: [PATCH] Avoid possible crash when getting server properties.
|
||||
|
||||
The crash occurs when calling dls_device_get_all_props() for a content
|
||||
directory server that we have not yet subscribed to (that is,
|
||||
prv_cds_subscribed() returns FALSE in
|
||||
prv_get_system_update_id_for_props()). This crash is caused by an
|
||||
invalid GVariantBuilder passed to g_variant_builder_end() in
|
||||
prv_get_sleeping_for_props(), leading to a NULL result pointer being
|
||||
passed to dls_async_task_complete(). A GVariant is attempted to be
|
||||
constructed from this NULL pointer in dls_task_complete().
|
||||
|
||||
Here is the call chain that leads to the crash:
|
||||
|
||||
dls_device_get_all_props()
|
||||
prv_get_system_update_id_for_props()
|
||||
gupnp_service_proxy_begin_action("GetSystemUpdateID") -> prv_system_update_id_for_props_cb()
|
||||
prv_system_update_id_for_props_cb()
|
||||
prv_get_sr_token_for_props()
|
||||
prv_get_sleeping_for_props()
|
||||
dls_async_task_complete()
|
||||
cb_data->cb() -> prv_async_task_complete()
|
||||
prv_async_task_complete()
|
||||
dls_task_complete()
|
||||
g_variant_new()
|
||||
|
||||
The crash was most likely observed when a device running Plex Media
|
||||
Server was present on the network.
|
||||
|
||||
This commit moves the call of g_variant_builder_end() in
|
||||
prv_system_update_id_for_props_cb() (which invalidates the
|
||||
GVariantBuilder used later in prv_get_sleeping_for_props()) to the
|
||||
error handling branch. This leaves the GVariantBuilder alone and
|
||||
allows prv_get_sr_token_for_props() or one of its descendants to call
|
||||
g_variant_builder_end() and complete the task.

Subject: [PATCH] Port to gupnp-1.2
|
||||
|
||||
gupnp_context_get_host_ip has been deprecated for a long time, as
|
||||
the host-ip property moved to gssdp.
|
||||
|
||||
There is also a ton of new deprecations but I will address that separately.
