Reinette Chatre de0bd50845 iwlwifi: fix potential rx buffer loss ... RX handling maintains a few lists that keep track of the RX buffers. Buffers move from one list to the other as they are used, replenished, and again made available for usage. In one such instance, when a buffer is used it enters the "rx_used" list. When buffers are replenished an skb is attached to the buffer and it is moved to the "rx_free" list. The problem here is that the buffer is first removed from the "rx_used" list _before_ the skb is allocated. Thus, if the skb allocation fails this buffer remains removed from the "rx_used" list and is thus lost for future usage. Fix this by first allocating the skb before trying to attach it to a list. We add an additional check to not do this unnecessarily. Reported-by: Rick Farrington <rickdic@hotmail.com> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.
