libcamera: ipc_pipe: Do not run memcpy with null arguments
IPCMessage::payload() converts the IPCMessage into an IPCUnixSocket
payload. However, if IPCMessage is constructed with one of the
following constructors -
IPCMessage::IPCMessage(),
IPCMessage::IPCMessage(uint32_t cmd)
IPCMessage::IPCMessage(const Header &header)
The data_ vector of IPCMessage is empty and uninitialised. In that
case, IPCMessage::payload will try to memcpy() an empty data_ vector
which can lead to invoking memcpy() with a nullptr parameter, which
is then identified by the address sanity checker.. Add a non-empty
data_ vector check to avoid it.
The issue is noticed by running a test manually, testing the vimc
IPA code paths in isolated mode. It is only noticed when the test
is compiled with -Db_sanitize=address,undefined meson built-in option.
ipc_pipe.cpp:110:8: runtime error: null pointer passed as argument 2, which is declared to never be null
