The big differences between RDS 3.0 and 3.1 are protocol-level flow control, and with 3.1 the header is in front of the data. The header always ends up in the header buffer, and the data goes in the data page. In 3.0 our "header" is a trailer, and will end up either in the data page, the header buffer, or split across the two. Since 3.1 is backwards- compatible with 3.0, we need to continue to support these cases. This patch does that -- if using RDS 3.0 wire protocol, it will copy the header from wherever it ended up into the header buffer.

RDS on IB uses privdata to do protocol version negotiation. Apparently the IB stack will return a larger privdata buffer than the struct we were expecting.

During large updates there could be triggered warnings like: "Fix inflate_threshold_root. Now=25 size=11 bits" if inflate() of the root node isn't finished in 10 loops. It should be much rarer now, after changing the threshold from 15 to 25, and a temporary problem, so this patch tries to handle it automatically using a fix variable to increase by one inflate threshold for next root resizes (up to the 35 limit, max fix = 10). The fix variable is decreased when root's inflate() finishes below 7 loops (even if some other, smaller table/ trie is updated -- for simplicity the fix variable is global for now).

During trie_rebalance() we free memory after resizing with call_rcu(), but large updates, especially with PREEMPT_NONE configs, can cause memory stresses, so this patch calls synchronize_rcu() in tnode_free_flush() after each sync_pages to guarantee such freeing (especially before resizing the root node). The value of sync_pages = 128 is based on Pawel Staszewski's tests as the lowest which doesn't hinder updating times. (For testing purposes there was a sysfs module parameter to change it on demand, but it's removed until we're sure it could be really useful.) The patch is based on suggestions by: Paul E.

The connector test code currently does not work out of the box. This is because it uses a connector id that is above the registered limit. So rather than force people to stumble through undocumented code wondering why it isn't working, have the test code use one of the "private" ids by default. While I'm in here, clean up the code (kernel and user app) so that it's a bit more user friendly and verbose in significant things that it does. Terse test code wastes people time as they simply enumerate it with all the same kind of debug messages to get a better feel of what code is running at any time.

The connector documentation states that the argument to the callback function is always a pointer to a struct cn_msg, but rather than encode it in the API itself, it uses a void pointer everywhere. This doesn't make much sense to encode the pointer in documentation as it prevents proper C type checking from occurring and can easily allow people to use the wrong pointer type. So convert the argument type to an explicit struct cn_msg pointer. Signed-off-by: NMike Frysinger <vapier@gentoo.org> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Commit e912b114 (net: sk_prot_alloc() should not blindly overwrite memory) took care of not zeroing whole new socket at allocation time. sock_copy() is another spot where we should be very careful. We should not set refcnt to a non null value, until we are sure other fields are correctly setup, or a lockless reader could catch this socket by mistake, while not fully (re)initialized. This patch puts sk_node & sk_refcnt to the very beginning of struct sock to ease sock_copy() & sk_prot_alloc() job. We add appropriate smp_wmb() before sk_refcnt initializations to match our RCU requirements (changes to sock keys should be committed to memory before sk_refcnt setting) Signed-off-by: NEric Dumazet <eric.dumazet@gmail.com> Signed-off-by: NDavid S.

E100 places it's RX packet descriptors inside skb->data and uses them with bidirectional streaming DMA mapping.

Bonding device forbids slave device of different types under the same master. However, it is possible for a bonding master to change type during its lifetime. This can be either from ARPHRD_ETHER to ARPHRD_INFINIBAND or the other way arround. The change of type requires device level multicast address cleanup because device level multicast addresses depend on the device type. The patch adds a call to dev_close() before the bonding master changes type and dev_open() just after that. In the example below I enslaved an IPoIB device (ib0) under bond0. Since each bonding master starts as device of type ARPHRD_ETHER by default, a change of type occurs when ib0 is enslaved. This is how /proc/net/dev_mcast looks like without the patch 5 bond0 1 0 00ffffffff12601bffff000000000001ff96ca05 5 bond0 1 0 01005e000116 5 bond0 1 0 01005e7ffffd 5 bond0 1 0 01005e000001 5 bond0 1 0 333300000001 6 ib0 1 0 00ffffffff12601bffff000000000001ff96ca05 6 ib0 1 0 333300000001 6 ib0 1 0 01005e000001 6 ib0 1 0 01005e7ffffd 6 ib0 1 0 01005e000116 6 ib0 1 0 00ffffffff12401bffff00000000000000000001 6 ib0 1 0 00ffffffff12601bffff00000000000000000001 and this is how it looks like after the patch. 5 bond0 1 0 00ffffffff12601bffff000000000001ff96ca05 5 bond0 1 0 00ffffffff12601bffff00000000000000000001 5 bond0 1 0 00ffffffff12401bffff0000000000000ffffffd 5 bond0 1 0 00ffffffff12401bffff00000000000000000116 5 bond0 1 0 00ffffffff12401bffff00000000000000000001 6 ib0 1 0 00ffffffff12601bffff000000000001ff96ca05 6 ib0 1 0 00ffffffff12401bffff00000000000000000116 6 ib0 1 0 00ffffffff12401bffff0000000000000ffffffd 6 ib0 2 0 00ffffffff12401bffff00000000000000000001 6 ib0 2 0 00ffffffff12601bffff00000000000000000001 Signed-off-by: NMoni Shoua <monis@voltaire.com> Signed-off-by: NJay Vosburgh <fubar@us.ibm.com> Signed-off-by: NDavid S.

When a slab cache uses SLAB_DESTROY_BY_RCU, we must be careful when allocating objects, since slab allocator could give a freed object still used by lockless readers. In particular, nf_conntrack RCU lookups rely on ct->tuplehash[xxx].hnnode.next being always valid (ie containing a valid 'nulls' value, or a valid pointer to next object in hash chain.) kmem_cache_zalloc() setups object with NULL values, but a NULL value is not valid for ct->tuplehash[xxx].hnnode.next. Fix is to call kmem_cache_alloc() and do the zeroing ourself. As spotted by Patrick, we also need to make sure lookup keys are committed to memory before setting refcount to 1, or a lockless reader could get a reference on the old version of the object. Its key re-check could then pass the barrier. Signed-off-by: NEric Dumazet <eric.dumazet@gmail.com> Signed-off-by: NPatrick McHardy <kaber@trash.net>
