When there are bitflips, we have to set these bits again to show the upper layers a completely erased page. When a bitflip happens in the exact byte where the bad block marker is, then this byte is swapped with another byte in block_mark_swapping(). The correction code then detects a bitflip in another subpage and no longer corrects the bitflip where it really happens. Correct this behaviour by calling block_mark_swapping() after the bitflips have been corrected.

A Multicast Router will listen on address ff02::16 for MLDv2 messages. Currently, MLDv2 messages originating from a Multicast Listener running on the same host as the Multicast Router are not being delivered to the Multicast Router. This is due to dst.input being assigned the default value of dst_discard. This results in the packet being looped back but discarded before being delivered to the Multicast Router. This patch sets dst.input to ip6_input to ensure a looped back packet is delivered to the Multicast Router. Signed-off-by: Brendan McGrath <redmcg(a)redmandi.dyndns.org> Signed-off-by: David S.
