    [NETLINK]: Don't BUG on undersized allocations · 26932566
    Patrick McHardy authored
    Currently netlink users BUG when the allocated skb for an event
    notification is undersized. While this is certainly a kernel bug,
    its not critical and crashing the kernel is too drastic, especially
    when considering that these errors have appeared multiple times in
    the past and it BUGs even if no listeners are present.
    
    This patch replaces BUG by WARN_ON and changes the notification
    functions to inform potential listeners of undersized allocations
    using a unique error code (EMSGSIZE).
