Up until now we have only used cpu_to_chip_id() in the topology code, which is only used on SMP builds. However my recent commit a4da0d50 "Implement arch_get_random_long/int() for powernv" added a usage when SMP=n, breaking the build. Move cpu_to_chip_id() into prom.c so it is available for SMP=n builds. We would move the extern to prom.h, but that breaks the include in topology.h. Instead we leave it in smp.h, but move it out of the CONFIG_SMP #ifdef. We also need to include asm/smp.h in rng.c, because the linux version skips asm/smp.h on UP. What a mess. Signed-off-by:

I encountered following issue: [ 0.283035] ibmvscsi 30000015: couldn't initialize event pool [ 5.688822] ibmvscsi: probe of 30000015 failed with error -1 which prevents the storage from being recognized, and the machine from booting. After some digging, it seems that it is caused by commit 4886c399 as dma_mask pointer in viodev->dev is not set, so in dma_set_mask_and_coherent(), dma_set_coherent_mask() is not called because dma_set_mask(), which is dma_set_mask_pSeriesLP() returned EIO. While before the commit, dma_set_coherent_mask() is always called. I tried to replace dma_set_mask_and_coherent() with dma_coerce_mask_and_coherent(), and the machine could boot again. Signed-off-by:

Commit fba2369e (mm: use vm_unmapped_area() on powerpc architecture) has a bug in slice_scan_available() where we compare an unsigned long (high_slices) against a shifted int. As a result, comparisons against the top 32 bits of high_slices (representing the top 32TB) always returns 0 and the top of our mmap region is clamped at 32TB This also breaks mmap randomisation since the randomised address is always up near the top of the address space and it gets clamped down to 32TB.

When reading from the dispatch trace log (dtl) userspace interface, I sometimes see duplicate entries.

It appears that driver runs into a problem here if fibsize is too small because we allocate user_srbcmd with fibsize size only but later we access it until user_srbcmd->sg.count to copy it over to srbcmd. It is not correct to test (fibsize < sizeof(*user_srbcmd)) because this structure already includes one sg element and this is not needed for commands without data. So, we would recommend to add the following (instead of test for fibsize == 0). Signed-off-by:

Pull networking fixes from David Miller: "Mostly these are fixes for fallout due to merge window changes, as well as cures for problems that have been with us for a much longer period of time" 1) Johannes Berg noticed two major deficiencies in our genetlink registration. Some genetlink protocols we passing in constant counts for their ops array rather than something like ARRAY_SIZE(ops) or similar. Also, some genetlink protocols were using fixed IDs for their multicast groups. We have to retain these fixed IDs to keep existing userland tools working, but reserve them so that other multicast groups used by other protocols can not possibly conflict. In dealing with these two problems, we actually now use less state management for genetlink operations and multicast groups. 2) When configuring interface hardware timestamping, fix several drivers that simply do not validate that the hwtstamp_config value is one the driver actually supports. From Ben Hutchings. 3) Invalid memory references in mwifiex driver, from Amitkumar Karwar. 4) In dev_forward_skb(), set the skb->protocol in the right order relative to skb_scrub_packet(). From Alexei Starovoitov. 5) Bridge erroneously fails to use the proper wrapper functions to make calls to netdev_ops->ndo_vlan_rx_{add,kill}_vid. Fix from Toshiaki Makita. 6) When detaching a bridge port, make sure to flush all VLAN IDs to prevent them from leaking, also from Toshiaki Makita. 7) Put in a compromise for TCP Small Queues so that deep queued devices that delay TX reclaim non-trivially don't have such a performance decrease. One particularly problematic area is 802.11 AMPDU in wireless. From Eric Dumazet. 8) Fix crashes in tcp_fastopen_cache_get(), we can see NULL socket dsts here. Fix from Eric Dumzaet, reported by Dave Jones. 9) Fix use after free in ipv6 SIT driver, from Willem de Bruijn. 10) When computing mergeable buffer sizes, virtio-net fails to take the virtio-net header into account. From Michael Dalton. 11) Fix seqlock deadlock in ip4_datagram_connect() wrt. statistic bumping, this one has been with us for a while. From Eric Dumazet. 12) Fix NULL deref in the new TIPC fragmentation handling, from Erik Hugne. 13) 6lowpan bit used for traffic classification was wrong, from Jukka Rissanen. 14) macvlan has the same issue as normal vlans did wrt. propagating LRO disabling down to the real device, fix it the same way. From Michal Kubecek. 15) CPSW driver needs to soft reset all slaves during suspend, from Daniel Mack. 16) Fix small frame pacing in FQ packet scheduler, from Eric Dumazet. 17) The xen-netfront RX buffer refill timer isn't properly scheduled on partial RX allocation success, from Ma JieYue. 18) When ipv6 ping protocol support was added, the AF_INET6 protocol initialization cleanup path on failure was borked a little. Fix from Vlad Yasevich. 19) If a socket disconnects during a read/recvmsg/recvfrom/etc that blocks we can do the wrong thing with the msg_name we write back to userspace. From Hannes Frederic Sowa. There is another fix in the works from Hannes which will prevent future problems of this nature. 20) Fix route leak in VTI tunnel transmit, from Fan Du. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (106 commits) genetlink: make multicast groups const, prevent abuse genetlink: pass family to functions using groups genetlink: add and use genl_set_err() genetlink: remove family pointer from genl_multicast_group genetlink: remove genl_unregister_mc_group() hsr: don't call genl_unregister_mc_group() quota/genetlink: use proper genetlink multicast APIs drop_monitor/genetlink: use proper genetlink multicast APIs genetlink: only pass array to genl_register_family_with_ops() tcp: don't update snd_nxt, when a socket is switched from repair mode atm: idt77252: fix dev refcnt leak xfrm: Release dst if this dst is improper for vti tunnel netlink: fix documentation typo in netlink_set_err() be2net: Delete secondary unicast MAC addresses during be_close be2net: Fix unconditional enabling of Rx interface options net, virtio_net: replace the magic value ping: prevent NULL pointer dereference on write to msg_name bnx2x: Prevent "timeout waiting for state X" bnx2x: prevent CFC attention bnx2x: Prevent panic during DMAE timeout ...

Johannes Berg says: ==================== genetlink: clean up multicast group APIs The generic netlink multicast group registration doesn't have to be dynamic, and can thus be simplified just like I did with the ops. This removes some complexity in registration code. Additionally, two users of generic netlink already use multicast groups in a wrong way, add workarounds for those two to keep the userspace API working, but at the same time make them not clash with other users of multicast groups as might happen now. While making it all a bit easier, also prevent such abuse by adding checks to the APIs so each family can only use the groups it owns. ==================== Signed-off-by:

Register generic netlink multicast groups as an array with the family and give them contiguous group IDs. Then instead of passing the global group ID to the various functions that send messages, pass the ID relative to the family - for most families that's just 0 because the only have one group. This avoids the list_head and ID in each group, adding a new field for the mcast group ID offset to the family. At the same time, this allows us to prevent abusing groups again like the quota and dropmon code did, since we can now check that a family only uses a group it owns. Signed-off-by:

The quota code is abusing the genetlink API and is using its family ID as the multicast group ID, which is invalid and may belong to somebody else (and likely will.) Make the quota code use the correct API, but since this is already used as-is by userspace, reserve a family ID for this code and also reserve that group ID to not break userspace assumptions.

The drop monitor code is abusing the genetlink API and is statically using the generic netlink multicast group 1, even if that group belongs to somebody else (which it invariably will, since it's not reserved.) Make the drop monitor code use the proper APIs to reserve a group ID, but also reserve the group id 1 in generic netlink code to preserve the userspace API. Since drop monitor can be a module, don't clear the bit for it on unregistration. Acked-by:

As suggested by David Miller, make genl_register_family_with_ops() a macro and pass only the array, evaluating ARRAY_SIZE() in the macro, this is a little safer. The openvswitch has some indirection, assing ops/n_ops directly in that code. This might ultimately just assign the pointers in the family initializations, saving the struct genl_family_and_ops and code (once mcast groups are handled differently.) Signed-off-by:

snd_nxt must be updated synchronously with sk_send_head. Otherwise tp->packets_out may be updated incorrectly, what may bring a kernel panic. Here is a kernel panic from my host. [ 103.043194] BUG: unable to handle kernel NULL pointer dereference at 0000000000000048 [ 103.044025] IP: [<ffffffff815aaaaf>] tcp_rearm_rto+0xcf/0x150 ... [ 146.301158] Call Trace: [ 146.301158] [<ffffffff815ab7f0>] tcp_ack+0xcc0/0x12c0 Before this panic a tcp socket was restored. This socket had sent and unsent data in the write queue. Sent data was restored in repair mode, then the socket was switched from reapair mode and unsent data was restored. After that the socket was switched back into repair mode. In that moment we had a socket where write queue looks like this: snd_una snd_nxt write_seq |_________|________| | sk_send_head After a second switching from repair mode the state of socket was changed: snd_una snd_nxt, write_seq |_________ ________| | sk_send_head This state is inconsistent, because snd_nxt and sk_send_head are not synchronized. Bellow you can find a call trace, how packets_out can be incremented twice for one skb, if snd_nxt and sk_send_head are not synchronized. In this case packets_out will be always positive, even when sk_write_queue is empty. tcp_write_wakeup skb = tcp_send_head(sk); tcp_fragment if (!before(tp->snd_nxt, TCP_SKB_CB(buff)->end_seq)) tcp_adjust_pcount(sk, skb, diff); tcp_event_new_data_sent tp->packets_out += tcp_skb_pcount(skb); I think update of snd_nxt isn't required, when a socket is switched from repair mode. Because it's initialized in tcp_connect_init. Then when a write queue is restored, snd_nxt is incremented in tcp_event_new_data_sent, so it's always is in consistent state. I have checked, that the bug is not reproduced with this patch and all tests about restoring tcp connections work fine.
