Long story short... the buffer is created by the Corosync IPC code.
See:
gboolean ais_dispatch(int sender, gpointer user_data)
{
int rc = CS_OK;
char *buffer = NULL;
gboolean good = TRUE;
gboolean (*dispatch)(AIS_Message*,char*,int) = user_data;
rc = coroipcc_dispatch_get (ais_ipc_handle, (void**)&buffer, 0);
// passing in a pointer to a NULL pointer, nothing allocated yet
...
}
Angus is the corosync IPC specialist, perhaps he has some insights as
to your alignment issues.
I know shared memory is involved somehow, perhaps that is complicating things.
I also note that AIS_Message should in theory already be aligned, at
least to my reading of it.
struct crm_ais_msg_s
{
coroipc_response_header_t header __attribute__((aligned(8)));
