2015-03-29net: dsa: mv88e6xxx: Disable Message Port bit for CPU portGuenter Roeck
Datasheet says that the Message Port bit should not be set for the CPU port. Having it set causes DSA tagged packets to be sent to the CPU port roughly every 30 seconds. Those packets are the same as real packets forwarded between switch ports if the switch is configured for switching between multiple ports. The packets are then bridged by the software bridge, resulting in duplicated packets on the network.

2015-03-29netns: don't clear nsid too early on removalNicolas Dichtel
With the current code, ids are removed too early. Suppose you have an ipip interface that stands in the netns foo and its link part in the netns bar (so the netns bar has an nsid into the netns foo). Now, you remove the netns bar: - the bar nsid into the netns foo is removed - the netns exit method of ipip is called, thus our ipip iface is removed: => a netlink message is sent in the netns foo to advertise this deletion => this netlink message requests an nsid for bar, thus a new nsid is allocated for bar and never removed. We must remove nsids when we are sure that nobody will refer to netns currently cleaned.

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for your net-next tree. Basically, nf_tables updates to add the set extension infrastructure and finish the transaction for sets from Patrick McHardy. More specifically, they are: 1) Move netns to basechain and use recently added possible_net_t, from Patrick McHardy. 2) Use LOGLEVEL_<FOO> from nf_log infrastructure, from Joe Perches. 3) Restore nf_log_trace that was accidentally removed during conflict resolution. 4) nft_queue does not depend on NETFILTER_XTABLES, starting from here all patches from Patrick McHardy. 5) Use raw_smp_processor_id() in nft_meta. Then, several patches to prepare ground for the new set extension infrastructure: 6) Pass object length to the hash callback in rhashtable as needed by the new set extension infrastructure. 7) Cleanup patch to restore struct nft_hash as wrapper for struct rhashtable 8) Another small source code readability cleanup for nft_hash. 9) Convert nft_hash to rhashtable callbacks. And finally... 10) Add the new set extension infrastructure. 11) Convert the nft_hash and nft_rbtree sets to use it. 12) Batch set element release to avoid several RCU grace period in a row and add new function nft_set_elem_destroy() to consolidate set element release. 13) Return the set extension data area from nft_lookup. 14) Refactor existing transaction code to add some helper functions and document it. 15) Complete the set transaction support, using similar approach to what we already use, to activate/deactivate elements in an atomic fashion. ==================== Signed-off-by: David S.

2015-03-29tipc: involve reference counter for node structureYing Xue
TIPC node hash node table is protected with rcu lock on read side. tipc_node_find() is used to look for a node object with node address through iterating the hash node table. As the entire process of what tipc_node_find() traverses the table is guarded with rcu read lock, it's safe for us. However, when callers use the node object returned by tipc_node_find(), there is no rcu read lock applied. Therefore, this is absolutely unsafe for callers of tipc_node_find(). Now we introduce a reference counter for node structure. Before tipc_node_find() returns node object to its caller, it first increases the reference counter. Accordingly, after its caller used it up, it decreases the counter again. This can prevent a node being used by one thread from being freed by another thread.

But especially when the retransmission of broadcast link is failed, bclink->lock is first held in tipc_bclink_rcv(), and n_ptr->lock is taken in link_retransmit_failure() called by tipc_link_retransmit() subsequently, which is demonstrated on CPU0. As a result, deadlock occurs. If the order of holding the two locks happening on CPU0 is reversed, the deadlock risk will be relieved. Therefore, the node lock taken in link_retransmit_failure() originally is moved to tipc_bclink_rcv() so that it's obtained before bclink lock. But the precondition of the adjustment of node lock is that responding to bclink reset event must be moved from tipc_bclink_unlock() to tipc_node_unlock().

2015-03-29cxgb4: Allocate dynamic mem. for egress and ingress queue mapsHariprasad Shenai
QIDs (egress/ingress) from firmware in FW_*_CMD.alloc command can be anywhere in the range from EQ(IQFLINT)_START to EQ(IQFLINT)_END. For eg, in the first load eqid can be from 100 to 300. In the next load it can be from 301 to 500 (assume eq_start is 100 and eq_end is 1000). The driver was assuming them to always start from EQ(IQFLINT)_START till MAX_EGRQ(INGQ). This was causing stack overflow and subsequent crash. Fixed it by dynamically allocating memory (of qsize (x_END - x_START + 1)) for these structures.

2015-03-29usbnet: Fix tx_bytes statistic running backward in cdc_ncmBen Hutchings
cdc_ncm disagrees with usbnet about how much framing overhead should be counted in the tx_bytes statistics, and tries 'fix' this by decrementing tx_bytes on the transmit path. But statistics must never be decremented except due to roll-over; this will thoroughly confuse user-space. Also, tx_bytes is only incremented by usbnet in the completion path. Fix this by requiring drivers that set FLAG_MULTI_FRAME to set a tx_bytes delta along with the tx_packets count.

2015-03-29usbnet: Fix tx_packets stat for FLAG_MULTI_FRAME driversBen Hutchings
Currently the usbnet core does not update the tx_packets statistic for drivers with FLAG_MULTI_PACKET and there is no hook in the TX completion path where they could do this. cdc_ncm and dependent drivers are bumping tx_packets stat on the transmit path while asix and sr9800 aren't updating it at all. Add a packet count in struct skb_data so these drivers can fill it in, initialise it to 1 for other drivers, and add the packet count to the tx_packets statistic on completion.
