2016-09-19genirq: Skip chained interrupt trigger setup if type is IRQ_TYPE_NONEMarc Zyngier1-2/+6
There is no point in trying to configure the trigger of a chained interrupt if no trigger information has been configured. At best this is ignored, and at the worse this confuses the underlying irqchip (which is likely not to handle such a thing), and unnecessarily alarms the user. Only apply the configuration if type is not IRQ_TYPE_NONE. Fixes: 1e12c4a9393b ("genirq: Correctly configure the trigger on chained interrupts") Reported-and-tested-by: Geert Uytterhoeven <[email protected]> Signed-off-by: Marc Zyngier <[email protected]> Link: https://lkml.kernel.org/r/CAMuHMdVW1eTn20=EtYcJ8hkVwohaSuH_yQXrY2MGBEvZ8fpFOg@mail.gmail.com Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Thomas Gleixner <[email protected]>
2016-09-19drm: Only use compat ioctl for addfb2 on X86/IA64Kristian H. Kristensen1-0/+4
Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an unaligned 64 bit field (modifier). This get packed differently between 32 bit and 64 bit modes on architectures that can handle unaligned 64 bit access (X86 and IA64). Other architectures pack the structs the same and don't need the compat wrapper. Use the same condition for drm_mode_fb_cmd2 as we use for drm_update_draw. Note that only the modifier will be packed differently between compat and non-compat versions. Reviewed-by: Rob Clark <[email protected]> Signed-off-by: Kristian H.

2016-09-17bna: fix crash in bnad_get_strings()Ivan Vecera1-27/+23
Commit 6e7333d "net: add rx_nohandler stat counter" added the new entry rx_nohandler into struct rtnl_link_stats64. Unfortunately the bna driver foolishly depends on the structure. It uses part of it for ethtool statistics and it's not bad but the driver assumes its size is constant as it defines string for each existing entry. The problem occurs when the structure is extended because you need to modify bna driver as well. If not any attempt to retrieve ethtool statistics results in crash in bnad_get_strings(). The patch changes BNAD_ETHTOOL_STATS_NUM so it counts real number of strings in the array and also removes rtnl_link_stats64 entries that are not used in output and are always zero.

2016-09-17net: avoid sk_forward_alloc overflowsEric Dumazet1-0/+10
A malicious TCP receiver, sending SACK, can force the sender to split skbs in write queue and increase its memory usage. Then, when socket is closed and its write queue purged, we might overflow sk_forward_alloc (It becomes negative) sk_mem_reclaim() does nothing in this case, and more than 2GB are leaked from TCP perspective (tcp_memory_allocated is not changed) Then warnings trigger from inet_sock_destruct() and sk_stream_kill_queues() seeing a not zero sk_forward_alloc All TCP stack can be stuck because TCP is under memory pressure. A simple fix is to preemptively reclaim from sk_mem_uncharge(). This makes sure a socket wont have more than 2 MB forward allocated, after burst and idle period.

In case of error during netback_probe() (e.g. an entry missing on the xenstore) netback_remove() is called on the new device, which will set the device backend state to XenbusStateClosed by calling set_backend_state(). However, the backend state wasn't initialized by netback_probe() at this point, which will cause and invalid transaction and set_backend_state() to BUG(). Initialize the backend state at the beginning of netback_probe() to XenbusStateInitialising, and create two new valid state transitions on set_backend_state(), from XenbusStateInitialising to XenbusStateClosed, and from XenbusStateInitialising to XenbusStateInitWait.

2016-09-17ACPI / platform: Pay attention to parent device's resourcesMika Westerberg1-1/+19
Given following simplified device hierarchy: // PCI device having BAR0 (RMEM) split between 4 GPIO devices. Device (P2S) { Name (_ADR, 0x000d0000) Device (GPO0) { Name (_HID, "INT3452") Name (_UID, 1) Name (_CRS, ResourceTemplate () { Memory32Fixed (ReadWrite, 0, 0x4000, RMEM + 0x0000) }) } Device (GPO1) { Name (_HID, "INT3452") Name (_UID, 2) Name (_CRS, ResourceTemplate () { Memory32Fixed (ReadWrite, 0, 0x4000, RMEM + 0x4000) }) } Device (GPO2) { Name (_HID, "INT3452") Name (_UID, 3) Name (_CRS, ResourceTemplate () { Memory32Fixed (ReadWrite, 0, 0x4000, RMEM + 0x8000) }) } Device (GPO3) { Name (_HID, "INT3452") Name (_UID, 4) Name (_CRS, ResourceTemplate () { Memory32Fixed (ReadWrite, 0, 0x4000, RMEM + 0xc000) }) } } The current ACPI platform enumeration code allocates resources from the global MMIO resource pool (/proc/iomem) for all the four GPIO devices. After this PCI core calls pcibios_resource_survey() to allocate resources for all PCI devices including the parent device for these GPIO devices (P2S). Since that resource range has already been reserved the allocation fails. The reason for this is that we never bother with parent device's resources when ACPI platform devices are created. Fix this by checking whether there is a parent device and in that case make sure we assign correct parent resource to the resources for the child ACPI platform device. Currently we only deal with parent devices if they are PCI devices but we may expand this later to cover other bus types as well.

2016-09-17ACPI / sysfs: Fix an issue for LoadTable opcodeLv Zheng1-1/+3
OEM tables can be installed via RSDT/XSDT, in this case, they have already been created under /sys/firmware/acpi/tables. For this kind of tables, normally LoadTable opcode will be executed to load them. If LoadTable opcode is executed after acpi_sysfs_init(), acpi_sysfs_table_handler() will be invoked, thus a redundant table file will be created under /sys/firmware/acpi/tables/dynamic. Then running "acpidump" on such platform results in an error, complaining blank empty table (see Link 1 below). The bug can be reproduced by customizing an OEM1 table, allowing it to be overridden via 'table_sigs' (drivers/acpi/tables.c), adding the following code to the customized DSDT to load it: Name (OEMH, Zero) Name (OEMF, One) If (LEqual (OEMF, One)) { Store (LoadTable ("OEM1", "Intel", "Test"), OEMH) Store (Zero, OEMF) } In order to make sure that the OEM1 table is installed after acpi_sysfs_init(), acpi_sysfs_init() can be moved before invoking acpi_load_tables(). Then the following command execution result can be seen: # acpidump > acpidump.txt Could not read table header: /sysfs/firmware/acpi/tables/dynamic/OEM12 Could not get ACPI table at index 17, AE_BAD_HEADER Link: https://bugzilla.kernel.org/show_bug.cgi?id=150841 # [1] Link: https://github.com/acpica/acpica/commit/ed6a5fbc Reported-by: Jason Voelz <[email protected]> Reported-by: Francisco Leoner <[email protected]> Signed-off-by: Lv Zheng <[email protected]> Signed-off-by: Rafael J.

In platforms such as Rockchip's, the array of domains isn't always filled without holes, as which domains are present depend on the particular SoC revision. By allowing holes to be in the array, such SoCs can still use a single set of constants to index the array of power domains.

2016-09-16cpufreq: ti: Use generic platdev driverDave Gerlach1-0/+2
Now that the cpufreq-dt-platdev is used to create the cpufreq-dt platform device for all OMAP platforms and the platform code that did it before has been removed, add ti,am33xx and ti,dra7xx to the machine list in cpufreq-dt-platdev which had relied on the removed platform code to do this previously.

git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma Pull rdma fixes from Doug Ledford: "Round three of 4.8 rc fixes. This is likely the last rdma pull request this cycle. The new rxe driver had a few issues (you probably saw the boot bot bug report) and they should be addressed now. There are a couple other fixes here, mainly mlx4. There are still two outstanding issues that need resolved but I don't think their fix will make this kernel cycle.
