2017-04-18PCI: Add arch_can_pci_mmap_io() on architectures which can mmap() I/O spaceDavid Woodhouse

2017-04-18PCI: Add arch_can_pci_mmap_wc() macroDavid Woodhouse
Most of the almost-identical versions of pci_mmap_page_range() silently ignore the 'write_combine' argument and give uncached mappings. Yet we allow the PCIIOC_WRITE_COMBINE ioctl in /proc/bus/pci, expose the 'resourceX_wc' file in sysfs, and allow an attempted mapping to apparently succeed. To fix this, introduce a macro arch_can_pci_mmap_wc() which indicates whether the platform can do a write-combining mapping. On x86 this ends up being pat_enabled(), while the few other platforms that support it can just set it to a literal '1'.

2017-04-18ftrace: Move the probe function into the tracing directorySteven Rostedt (VMware)
As nothing outside the tracing directory uses the function probes mechanism, I'm moving the prototypes out of the include/linux/ftrace.h and into the local kernel/trace/trace.h header. I plan on making them hook to the trace_array structure which is local to kernel/trace, and I do not want to expose it to the rest of the kernel. This requires that the probe functions must also be local to tracing. But luckily nothing else uses them. Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>

2017-04-18sctp: process duplicated strreset out and addstrm out requests correctlyXin Long
Now sctp stream reconf will process a request again even if it's seqno is less than asoc->strreset_inseq. If one request has been done successfully and some data chunks have been accepted and then a duplicated strreset out request comes, the streamin's ssn will be cleared. It will cause that stream will never receive chunks any more because of unsynchronized ssn. It allows a replay attack. A similar issue also exists when processing addstrm out requests. It will cause more extra streams being added. This patch is to fix it by saving the last 2 results into asoc. When a duplicated strreset out or addstrm out request is received, reply it with bad seqno if it's seqno < asoc->strreset_inseq - 2, and reply it with the result saved in asoc if it's seqno >= asoc->strreset_inseq - 2. Note that it saves last 2 results instead of only last 1 result, because two requests can be sent together in one chunk. And note that when receiving a duplicated request, the receiver side will still reply it even if the peer has received the response. It's safe, As the response will be dropped by the peer.

2017-04-18mmc: sdio: fix alignment issue in struct sdio_funcHeiner Kallweit
Certain 64-bit systems (e.g. Amlogic Meson GX) require buffers to be used for DMA to be 8-byte-aligned. struct sdio_func has an embedded small DMA buffer not meeting this requirement. When testing switching to descriptor chain mode in meson-gx driver SDIO is broken therefore. Fix this by allocating the small DMA buffer separately as kmalloc ensures that the returned memory area is properly aligned for every basic data type.

2017-04-17Remove compat_sys_getdents64()Al Viro
Unlike normal compat syscall variants, it is needed only for biarch architectures that have different alignement requirements for u64 in 32bit and 64bit ABI *and* have __put_user() that won't handle a store of 64bit value at 32bit-aligned address. We used to have one such (ia64), but its biarch support has been gone since 2010 (after being broken in 2008, which went unnoticed since nobody had been using it). It had escaped removal at the same time only because back in 2004 a patch that switched several syscalls on amd64 from private wrappers to generic compat ones had switched to use of compat_sys_getdents64(), which hadn't needed (or used) a compat wrapper on amd64. Let's bury it - it's at least 7 years overdue. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2017-04-17nbd: add a basic netlink interfaceJosef Bacik
The existing ioctl interface for configuring NBD devices is a bit cumbersome and hard to extend. The other problem is we leave a userspace app sitting in it's syscall until the device disconnects, which is less than ideal. This patch introduces a netlink interface for adding and disconnecting nbd devices. This has the benefits of being easily extendable without breaking older userspace applications, and allows us to configure a nbd device without leaving a userspace app sitting waiting for the device to disconnect. With this interface we also gain the ability to configure more devices than are preallocated at insmod time. We also have gained the ability to not specify a particular device and be provided one for us so that userspace doesn't need to find a free device to configure.

2017-04-16i2c: core: Allow drivers to disable i2c-core irq mappingHans de Goede
By default the i2c-core will try to get an irq with index 0 on ACPI / of instantiated devices. This is troublesome on some ACPI systems where the irq info at index 0 in the CRS table may contain nonsense and/or point to an irqchip for which there is no Linux driver. If this happens then before this commit the driver's probe method would never get called because i2c_device_probe will try to get an irq by calling acpi_dev_gpio_irq_get which will always return -EPROBE in this case, as it waits for a matching irqchip driver to load. Thus causing the driver to not get a chance to bind. This commit adds a new disable_i2c_core_irq_mapping flag to struct i2c_driver which a driver can set to tell the core to skip irq mapping.

By default the i2c subsys creates an i2c-client for the first I2cSerialBus resource of an acpi_device, but some acpi_devices have multiple I2cSerialBus resources and we may want to instantiate i2c-clients for the others. This commit adds a new i2c_acpi_new_device function which can be used to create an i2c-client for any I2cSerialBus resource of an acpi_device.

2017-04-16lightnvm: submit erases using the I/O pathJavier González
Until now erases have been submitted as synchronous commands through a dedicated erase function. In order to enable targets implementing asynchronous erases, refactor the erase path so that it uses the normal async I/O submission functions. If a target requires sync I/O, it can implement it internally. Also, adapt rrpc to use the new erase path. Signed-off-by: Javier González <javier@cnexlabs.com> Fixed spelling error.

2017-04-15Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/netDavid S. Miller
Conflicts were simply overlapping changes. In the net/ipv4/route.c case the code had simply moved around a little bit and the same fix was made in both 'net' and 'net-next'. In the net/sched/sch_generic.c case a fix in 'net' happened at the same time that a new argument was added to qdisc_hash_add(). Signed-off-by: David S. Miller <davem@davemloft.net>

2017-04-15workqueue: Provide work_on_cpu_safe()Thomas Gleixner
work_on_cpu() is not protected against CPU hotplug. For code which requires to be either executed on an online CPU or to fail if the CPU is not available the callsite would have to protect against CPU hotplug. Provide a function which does get/put_online_cpus() around the call to work_on_cpu() and fails the call with -ENODEV if the target CPU is not online. Preparatory patch to convert several racy task affinity manipulations.

2017-04-15netfilter: kill the fake untracked conntrack objectsFlorian Westphal
resurrect an old patch from Pablo Neira to remove the untracked objects. Currently, there are four possible states of an skb wrt. conntrack. 1. No conntrack attached, ct is NULL. 2. Normal (kmem cache allocated) ct attached. 3. a template (kmalloc'd), not in any hash tables at any point in time 4. the 'untracked' conntrack, a percpu nf_conn object, tagged via IPS_UNTRACKED_BIT in ct->status. Untracked is supposed to be identical to case 1. It exists only so users can check -m conntrack --ctstate UNTRACKED vs. -m conntrack --ctstate INVALID e.g. attempts to set connmark on INVALID or UNTRACKED conntracks is supposed to be a no-op. Thus currently we need to check ct == NULL || nf_ct_is_untracked(ct) in a lot of places in order to avoid altering untracked objects. The other consequence of the percpu untracked object is that all -j NOTRACK (and, later, kfree_skb of such skbs) result in an atomic op (inc/dec the untracked conntracks refcount). This adds a new kernel-private ctinfo state, IP_CT_UNTRACKED, to make the distinction instead. The (few) places that care about packet invalid (ct is NULL) vs. packet untracked now need to test ct == NULL vs. ctinfo == IP_CT_UNTRACKED, but all other places can omit the nf_ct_is_untracked() check.
