Some of the instances of tcp_sack_block are host-endian, some - net-endian. Define struct tcp_sack_block_wire identical to struct tcp_sack_block with u32 replaced with __be32; annotate uses of tcp_sack_block replacing net-endian ones with tcp_sack_block_wire. Change is obviously safe since for cc(1) __be32 is typedefed to u32. Signed-off-by:

The move of qdisc destruction to a rcu callback broke locking in the entire qdisc layer by invalidating previously valid assumptions about the context in which changes to the qdisc tree occur. The two assumptions were: - since changes only happen in process context, read_lock doesn't need bottem half protection. Now invalid since destruction of inner qdiscs, classifiers, actions and estimators happens in the RCU callback unless they're manually deleted, resulting in dead-locks when read_lock in process context is interrupted by write_lock_bh in bottem half context. - since changes only happen under the RTNL, no additional locking is necessary for data not used during packet processing (f.e. u32_list). Again, since destruction now happens in the RCU callback, this assumption is not valid anymore, causing races while using this data, which can result in corruption or use-after-free. Instead of "fixing" this by disabling bottem halfs everywhere and adding new locks/refcounting, this patch makes these assumptions valid again by moving destruction back to process context. Since only the dev->qdisc pointer is protected by RCU, but ->enqueue and the qdisc tree are still protected by dev->qdisc_lock, destruction of the tree can be performed immediately and only the final free needs to happen in the rcu callback to make sure dev_queue_xmit doesn't access already freed memory.

Fix incorrect use of RB_EMPTY_NODE in htb_safe_rb_erase, which makes it skip nodes within the rbtree instead of nodes not in the tree, resulting in crashes later on. The root cause for this seems to be the very counter-intuitive behaviour of the RB_EMPTY_NODE macro, which returns _false_ when the node is empty. Signed-off-by:

This is just a minor buglet I came across by accident - when inet_init fails to register raw_prot, it jumps to out_unregister_udp_proto which should unregister UDP _and_ TCP. Signed-off-by:

Anyway, I've been asked to add support for managing DSCP codepoints, so one can test DiffServ capable routers. It's very simple code and is working for me. Signed-off-by:
