      Slab: Fix memory leak in fallback_alloc() · 481c5346
      Christoph Lameter authored
      The zonelist patches caused the loop that checks for available
      objects in permitted zones to not terminate immediately. One object
      per zone per allocation may be allocated and then abandoned.
      
      Break the loop when we have successfully allocated one object.

      Add return value to reserve_bootmem_node() · 71c2742f
      Bernhard Walle authored
      This patch changes the function reserve_bootmem_node() from void to int,
      returning -ENOMEM if the allocation fails.
      
      This fixes a build problem on x86 with CONFIG_KEXEC=y and
      CONFIG_NEED_MULTIPLE_NODES=y

      Receiving packets while we are cleaning up a network namespace is a
      racy proposition. It is possible when the packet arrives that we have
      removed some but not all of the state we need to fully process it.  We
      have the choice of either playing wack-a-mole with the cleanup routines
      or simply dropping packets when we don't have a network namespace to
      handle them.
      
      Since the check looks inexpensive in netif_receive_skb let's just
      drop the incoming packets.

      sctp: Make sure N * sizeof(union sctp_addr) does not overflow. · 735ce972
      David S. Miller authored
      As noticed by Gabriel Campana, the kmalloc() length arg
      passed in by sctp_getsockopt_local_addrs_old() can overflow
      if ->addr_num is large enough.
      
      Therefore, enforce an appropriate limit.
