This patch fixes a potential hole when configuring the cycle counter used to generate the nanosecond time clock. This clock is based off of the SYSTIME registers along with the TIMINCA registers. The TIMINCA register determines the increment to be added to the SYSTIME registers every DMA clock tick. This register needs to be reconfigured whenever the link-speed changes. However, the value calculated stays the same when link is down and when link is up. Misconfiguration can occur if the link status changes due to a reset, which causes the TIMINCA register to be reset. This reset puts the device in an unstable state where the SYSTIME registers stop incrementing and the PTP protocol does not function. The solution is to double check the TIMINCA value and always reset the value if the register is zero. This prevents a misconfiguration bug that halts the PHC. Signed-off-by:

/proc/net/ipv6_route reflects the contents of fib_table_hash. The proc handler is installed in ip6_route_net_init() whereas fib_table_hash is allocated in fib6_net_init() _after_ the proc handler has been installed. This opens up a short time frame to access fib_table_hash with its pants down. fib6_init() as a whole can't be moved to an earlier position as it also registers the rtnetlink message handlers which should be registered at the end. Therefore split it into fib6_init() which is run early and fib6_init_late() to register the rtnetlink message handlers. Signed-off-by:

Orphaning skb in dev_hard_start_xmit() makes bonding behavior unfriendly for applications sending big UDP bursts : Once packets pass the bonding device and come to real device, they might hit a full qdisc and be dropped. Without orphaning, the sender is automatically throttled because sk->sk_wmemalloc reaches sk->sk_sndbuf (assuming sk_sndbuf is not too big) We could try to defer the orphaning adding another test in dev_hard_start_xmit(), but all this seems of little gain, now that BQL tends to make packets more likely to be parked in Qdisc queues instead of NIC TX ring, in cases where performance matters.

bnx2x driver incorrectly sets ip_summed to CHECKSUM_UNNECESSARY on encapsulated segments. TCP stack happily accepts frames with bad checksums, if they are inside a GRE or IPIP encapsulation. Our understanding is that if no IP or L4 csum validation was done by the hardware, we should leave ip_summed as is (CHECKSUM_NONE), since hardware doesn't provide CHECKSUM_COMPLETE support in its cqe. Then, if IP/L4 checksumming was done by the hardware, set CHECKSUM_UNNECESSARY if no error was flagged. Patch based on findings and analysis from Robert Evans Signed-off-by:

Bogdan Hamciuc diagnosed and fixed following bug in netpoll_send_udp() : "skb->len += len;" instead of "skb_put(skb, len);" Meaning that _if_ a network driver needs to call skb_realloc_headroom(), only packet headers would be copied, leaving garbage in the payload. However the skb_realloc_headroom() must be avoided as much as possible since it requires memory and netpoll tries hard to work even if memory is exhausted (using a pool of preallocated skbs) It appears netpoll_send_udp() reserved 16 bytes for the ethernet header, which happens to work for typicall drivers but not all. Right thing is to use LL_RESERVED_SPACE(dev) (And also add dev->needed_tailroom of tailroom) This patch combines both fixes. Many thanks to Bogdan for raising this issue. Reported-by:

In the transmit path of the bonding driver, skb->cb is used to stash the skb->queue_mapping so that the bonding device can set its own queue mapping. This value becomes corrupted since the skb->cb is also used in __dev_xmit_skb. When transmitting through bonding driver, bond_select_queue is called from dev_queue_xmit. In bond_select_queue the original skb->queue_mapping is copied into skb->cb (via bond_queue_mapping) and skb->queue_mapping is overwritten with the bond driver queue. Subsequently in dev_queue_xmit, __dev_xmit_skb is called which writes the packet length into skb->cb, thereby overwriting the stashed queue mappping. In bond_dev_queue_xmit (called from hard_start_xmit), the queue mapping for the skb is set to the stashed value which is now the skb length and hence is an invalid queue for the slave device. If we want to save skb->queue_mapping into skb->cb[], best place is to add a field in struct qdisc_skb_cb, to make sure it wont conflict with other layers (eg : Qdiscc, Infiniband...) This patchs also makes sure (struct qdisc_skb_cb)->data is aligned on 8 bytes : netem qdisc for example assumes it can store an u64 in it, without misalignment penalty. Note : we only have 20 bytes left in (struct qdisc_skb_cb)->data[]. The largest user is CHOKe and it fills it. Based on a previous patch from Tom Herbert. Signed-off-by:
