It seems that when a PCI Express bridge is not in use and has no devices behind it, the ranges property is bogus. Specifically the size property is of the form [0xffffffff:...], and if you add this size to the resource start address the 64-bit calculation will overflow. Just check specifically for this size value signature and skip them. Signed-off-by:

Pull x86/apic updates from Thomas Gleixner: "This is a major overhaul to the x86 apic subsystem consisting of the following parts: - Remove obsolete APIC driver abstractions (David Rientjes) - Use the irqdomain facilities to dynamically allocate IRQs for IOAPICs. This is a prerequisite to enable IOAPIC hotplug support, and it also frees up wasted vectors (Jiang Liu) - Misc fixlets. Despite the hickup in Ingos previous pull request - caused by the missing fixup for the suspend/resume issue reported by Borislav - I strongly recommend that this update finds its way into 3.17. Some history for you: This is preparatory work for physical IOAPIC hotplug. The first attempt to support this was done by Yinghai and I shot it down because it just added another layer of obscurity and complexity to the already existing mess without tackling the underlying shortcomings of the current implementation. After quite some on- and offlist discussions, I requested that the design of this functionality must use generic infrastructure, i.e. irq domains, which provide all the mechanisms to dynamically map linux interrupt numbers to physical interrupts. Jiang picked up the idea and did a great job of consolidating the existing interfaces to manage the x86 (IOAPIC) interrupt system by utilizing irq domains. The testing in tip, Linux-next and inside of Intel on various machines did not unearth any oddities until Borislav exposed it to one of his oddball machines. The issue was resolved quickly, but unfortunately the fix fell through the cracks and did not hit the tip tree before Ingo sent the pull request. Not entirely Ingos fault, I also assumed that the fix was already merged when Ingo asked me whether he could send it. Nevertheless this work has a proper design, has undergone several rounds of review and the final fallout after applying it to tip and integrating it into Linux-next has been more than moderate. It's the ground work not only for IOAPIC hotplug, it will also allow us to move the lowlevel vector allocation into the irqdomain hierarchy, which will benefit other architectures as well. Patches are posted already, but they are on hold for two weeks, see below. I really appreciate the competence and responsiveness Jiang has shown in course of this endavour. So I'm sure that any fallout of this will be addressed in a timely manner. FYI, I'm vanishing for 2 weeks into my annual kids summer camp kitchen duty^Wvacation, while you folks are drooling at KS/LinuxCon :) But HPA will have a look at the hopefully zero fallout until I'm back" * 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (53 commits) x86, irq, PCI: Keep IRQ assignment for PCI devices during suspend/hibernation x86/apic/vsmp: Make is_vsmp_box() static x86, apic: Remove enable_apic_mode callback x86, apic: Remove setup_portio_remap callback x86, apic: Remove multi_timer_check callback x86, apic: Replace noop_check_apicid_used x86, apic: Remove check_apicid_present callback x86, apic: Remove mps_oem_check callback x86, apic: Remove smp_callin_clear_local_apic callback x86, apic: Replace trampoline physical addresses with defaults x86, apic: Remove x86_32_numa_cpu_node callback x86: intel-mid: Use the new io_apic interfaces x86, vsmp: Remove is_vsmp_box() from apic_is_clustered_box() x86, irq: Clean up irqdomain transition code x86, irq, devicetree: Release IOAPIC pin when PCI device is disabled x86, irq, SFI: Release IOAPIC pin when PCI device is disabled x86, irq, mpparse: Release IOAPIC pin when PCI device is disabled x86, irq, ACPI: Release IOAPIC pin when PCI device is disabled x86, irq: Introduce helper functions to release IOAPIC pin x86, irq: Simplify the way to handle ISA IRQ ...

If do_journal_release() races with do_journal_end() which requeues delayed works for transaction flushing, we can leave work items for flushing outstanding transactions queued while freeing them. That results in use after free and possible crash in run_timers_softirq(). Fix the problem by not requeueing works if superblock is being shut down (MS_ACTIVE not set) and using cancel_delayed_work_sync() in do_journal_release(). CC: stable@vger.kernel.org Signed-off-by:

Christopher reports that perf_event_print_debug() can crash in uniprocessor builds. The crash is due to pcr_ops being NULL. This happens because pcr_arch_init() is only invoked by smp_cpus_done() which only executes in SMP builds. init_hw_perf_events() is closely intertwined with pcr_ops being setup properly, therefore: 1) Call pcr_arch_init() early on from init_hw_perf_events(), instead of from smp_cpus_done(). 2) Do not hook up a PMU type if pcr_ops is NULL after pcr_arch_init(). 3) Move init_hw_perf_events to a later initcall so that it we will be sure to invoke pcr_arch_init() after all cpus are brought up. Finally, guard the one naked sequence of pcr_ops dereferences in __global_pmu_self() with an appropriate NULL check. Reported-by:

nmi_cpu_busy() is a SMP function call that just makes sure that all of the cpus are spinning using cpu cycles while the NMI test runs. It does not need to disable IRQs because we just care about NMIs executing which will even with 'normal' IRQs disabled. It is not legal to enable hard IRQs in a SMP cross call, in fact this bug triggers the BUG check in irq_work_run_list(): BUG_ON(!irqs_disabled()); Because now irq_work_run() is invoked from the tail of generic_smp_call_function_single_interrupt().

In case we configured the adapter to be a wake up source from Wake-on-LAN, but we never actually woke up using Wake-on-LAN, we will leave the adapter in MagicPacket matching mode, which prevents any other type of packets from reaching the RX engine. Fix this by calling bcmgenet_power_up() with GENET_POWER_WOL_MAGIC to restore the adapter configuration in bcmgenet_resume(). The second problem we had was an imbalanced clock disabling in bcmgenet_wol_resume(), the Wake-on-LAN slow clock is only enabled in bcmgenet_suspend() if we configured Wake-on-LAN, yet we unconditionally disabled the clock in bcmgenet_wol_resume().

When we bring the interface down, phy_stop() will schedule the PHY state machine to call our link adjustment callback. By the time we do so, we may have clock gated off the GENET hardware block, and this will cause bus errors to happen in bcmgenet_mii_setup(): Make sure that we only touch the UMAC_CMD register when there is an actual link. This is safe to do for two reasons: - updating the Ethernet MAC registers only make sense when a physical link is present - the PHY library state machine first set phydev->link = 0 before invoking phydev->adjust_link in the PHY_HALTED case Fixes: 24052408 ("net: bcmgenet: only update UMAC_CMD if something changed") Signed-off-by:

Make sure that we properly suspend and resume the PHY device when we enter low power modes. We had two calls to bcmgenet_mii_reset() which will issue a software-reset to the PHY without using the PHY library, get rid of them since they are completely bogus and mess up with the PHY library state. Make sure that we reset the PHY library cached values (link, pause and duplex) to allow the link adjustment callback to be invoked when needed.

bcmgenet_set_hw_params() will read the hardware version and compare it with the one we are getting from Device Tree. Due to the clock being enabled too late, bcmgenet_set_hw_params() will cause bus errors since the GENET hardware block is still gated off by the time bcmgenet_set_hw_params() is called, this will also make us fail the version check since we will read the value 0 from the hardware. Fix this by requesting the clock before the first piece of code that needs to access hardware register. Fixes: 1c1008c7 ("net: bcmgenet: add main driver file") Signed-off-by:

There is a long known problem with the netfront/netback interface: if the guest tries to send a packet which constitues more than MAX_SKB_FRAGS + 1 ring slots, it gets dropped. The reason is that netback maps these slots to a frag in the frags array, which is limited by size. Having so many slots can occur since compound pages were introduced, as the ring protocol slice them up into individual (non-compound) page aligned slots. The theoretical worst case scenario looks like this (note, skbs are limited to 64 Kb here): linear buffer: at most PAGE_SIZE - 17 * 2 bytes, overlapping page boundary, using 2 slots first 15 frags: 1 + PAGE_SIZE + 1 bytes long, first and last bytes are at the end and the beginning of a page, therefore they use 3 * 15 = 45 slots last 2 frags: 1 + 1 bytes, overlapping page boundary, 2 * 2 = 4 slots Although I don't think this 51 slots skb can really happen, we need a solution which can deal with every scenario. In real life there is only a few slots overdue, but usually it causes the TCP stream to be blocked, as the retry will most likely have the same buffer layout. This patch solves this problem by linearizing the packet. This is not the fastest way, and it can fail much easier as it tries to allocate a big linear area for the whole packet, but probably easier by an order of magnitude than anything else. Probably this code path is not touched very frequently anyway. Signed-off-by:

Also, the name of the struct is changed to drop the _t, to make the name look less typedef-like. The following Coccinelle semantic patch detects the case: @tn@ identifier i; type td; @@ -typedef struct i { ... } -td ; @@ type tn.td; identifier tn.i; @@ -td + struct i Signed-off-by:

Currently the functionality to untag traffic on input resides as part of the vlan module and is build only when VLAN support is enabled in the kernel. When VLAN is disabled, the function vlan_untag() turns into a stub and doesn't really untag the packets. This seems to create an interesting interaction between VMs supporting checksum offloading and some network drivers. There are some drivers that do not allow the user to change tx-vlan-offload feature of the driver. These drivers also seem to assume that any VLAN-tagged traffic they transmit will have the vlan information in the vlan_tci and not in the vlan header already in the skb. When transmitting skbs that already have tagged data with partial checksum set, the checksum doesn't appear to be updated correctly by the card thus resulting in a failure to establish TCP connections. The following is a packet trace taken on the receiver where a sender is a VM with a VLAN configued. The host VM is running on doest not have VLAN support and the outging interface on the host is tg3: 10:12:43.503055 52:54:00:ae:42:3f > 28:d2:44:7d:c2:de, ethertype 802.1Q (0x8100), length 78: vlan 100, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 27243, offset 0, flags [DF], proto TCP (6), length 60) 10.0.100.1.58545 > 10.0.100.10.ircu-2: Flags [S], cksum 0xdc39 (incorrect -> 0x48d9), seq 1069378582, win 29200, options [mss 1460,sackOK,TS val 4294837885 ecr 0,nop,wscale 7], length 0 10:12:44.505556 52:54:00:ae:42:3f > 28:d2:44:7d:c2:de, ethertype 802.1Q (0x8100), length 78: vlan 100, p 0, ethertype IPv4, (tos 0x0, ttl 64, id 27244, offset 0, flags [DF], proto TCP (6), length 60) 10.0.100.1.58545 > 10.0.100.10.ircu-2: Flags [S], cksum 0xdc39 (incorrect -> 0x44ee), seq 1069378582, win 29200, options [mss 1460,sackOK,TS val 4294838888 ecr 0,nop,wscale 7], length 0 This connection finally times out. I've only access to the TG3 hardware in this configuration thus have only tested this with TG3 driver. There are a lot of other drivers that do not permit user changes to vlan acceleration features, and I don't know if they all suffere from a similar issue. The patch attempt to fix this another way. It moves the vlan header stipping code out of the vlan module and always builds it into the kernel network core. This way, even if vlan is not supported on a virtualizatoin host, the virtual machines running on top of such host will still work with VLANs enabled.
