Linus Lüssing a516993f0a net: fix wrong skb_get() usage / crash in IGMP/MLD parsing code ... The recent refactoring of the IGMP and MLD parsing code into ipv6_mc_check_mld() / ip_mc_check_igmp() introduced a potential crash / BUG() invocation for bridges: I wrongly assumed that skb_get() could be used as a simple reference counter for an skb which is not the case. skb_get() bears additional semantics, a user count. This leads to a BUG() invocation in pskb_expand_head() / kernel panic if pskb_may_pull() is called on an skb with a user count greater than one - unfortunately the refactoring did just that. Fixing this by removing the skb_get() call and changing the API: The caller of ipv6_mc_check_mld() / ip_mc_check_igmp() now needs to additionally check whether the returned skb_trimmed is a clone.
