The parameter order change of the rebased patch was > not re-applied as expected. This causes a memory leak and can cause crashes > when out-of-order packets are received. hlist_add_behind will try to access the > uninitalized list pointers of frag_entry_new to find the previous/next entry > and may modify/read random memory locations. > > Signed-off-by: Sven Eckelmann <sven@...fation.org> > Cc: Andrew Morton <akpm@...ux-foundation.org> Applied, thank you. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
