exit_thread: accept a task parameter to be exited
We need to call exit_thread from copy_process in a fail path. So make it accept task_struct as a parameter. [v2] * s390: exit_thread_runtime_instr doesn't make sense to be called for non-current tasks. * arm: fix the comment in vfp_thread_copy * change 'me' to 'tsk' for task_struct * now we can change only archs that actually have exit_thread [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Jiri Slaby <jslaby@suse.cz> Cc: "David S.

Pull networking updates from David Miller: "Highlights: 1) Support more Realtek wireless chips, from Jes Sorenson. 2) New BPF types for per-cpu hash and arrap maps, from Alexei Starovoitov. 3) Make several TCP sysctls per-namespace, from Nikolay Borisov. 4) Allow the use of SO_REUSEPORT in order to do per-thread processing of incoming TCP/UDP connections. The muxing can be done using a BPF program which hashes the incoming packet. From Craig Gallek. 5) Add a multiplexer for TCP streams, to provide a messaged based interface. BPF programs can be used to determine the message boundaries. From Tom Herbert. 6) Add 802.1AE MACSEC support, from Sabrina Dubroca. 7) Avoid factorial complexity when taking down an inetdev interface with lots of configured addresses. We were doing things like traversing the entire address less for each address removed, and flushing the entire netfilter conntrack table for every address as well. 8) Add and use SKB bulk free infrastructure, from Jesper Brouer. 9) Allow offloading u32 classifiers to hardware, and implement for ixgbe, from John Fastabend. 10) Allow configuring IRQ coalescing parameters on a per-queue basis, from Kan Liang. 11) Extend ethtool so that larger link mode masks can be supported. From David Decotigny. 12) Introduce devlink, which can be used to configure port link types (ethernet vs Infiniband, etc.), port splitting, and switch device level attributes as a whole. From Jiri Pirko. 13) Hardware offload support for flower classifiers, from Amir Vadai. 14) Add "Local Checksum Offload". Basically, for a tunneled packet the checksum of the outer header is 'constant' (because with the checksum field filled into the inner protocol header, the payload of the outer frame checksums to 'zero'), and we can take advantage of that in various ways.

ipv4: Update parameters for csum_tcpudp_magic to their original types
This patch updates all instances of csum_tcpudp_magic and csum_tcpudp_nofold to reflect the types that are usually used as the source inputs. For example the protocol field is populated based on nexthdr which is actually an unsigned 8 bit value. The length is usually populated based on skb->len which is an unsigned integer. This addresses an issue in which the IPv6 function csum_ipv6_magic was generating a checksum using the full 32b of skb->len while csum_tcpudp_magic was only using the lower 16 bits. As a result we could run into issues when attempting to adjust the checksum as there was no protocol agnostic way to update it. With this change the value is still truncated as many architectures use "(len + proto) << 8", however this truncation only occurs for values greater than 16776960 in length and as such is unlikely to occur as we stop the inner headers at ~64K in size. I did have to make a few minor changes in the arm, mn10300, nios2, and score versions of the function in order to support these changes as they were either using things such as an OR to combine the protocol and length, or were using ntohs to convert the length which would have truncated the value. I also updated a few spots in terms of whitespace and type differences for the addresses. Most of this was just to make sure all of the definitions were in sync going forward.

arch/hotplug: Call into idle with a proper state
Let the non boot cpus call into idle with the corresponding hotplug state, so the hotplug core can handle the further bringup. That's a first step to convert the boot side of the hotplugged cpus to do all the synchronization with the other side through the state machine. For now it'll only start the hotplug thread and kick the full bringup of the cpu.

net: Facility to report route quality of connected sockets
This patch add the SO_CNX_ADVICE socket option (setsockopt only). The purpose is to allow an application to give feedback to the kernel about the quality of the network path for a connected socket. The value argument indicates the type of quality report. For this initial patch the only supported advice is a value of 1 which indicates "bad path, please reroute"-- the action taken by the kernel is to call dst_negative_advice which will attempt to choose a different ECMP route, reset the TX hash for flow label and UDP source port in encapsulation, etc. This facility should be useful for connected UDP sockets where only the application can provide any feedback about path quality. It could also be useful for TCP applications that have additional knowledge about the path outside of the normal TCP control loop.

Merge branch 'strscpy' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile
Pull strscpy string copy function implementation from Chris Metcalf. Chris sent this during the merge window, but I waffled back and forth on the pull request, which is why it's going in only now. The new "strscpy()" function is definitely easier to use and more secure than either strncpy() or strlcpy(), both of which are horrible nasty interfaces that have serious and irredeemable problems. strncpy() has a useless return value, and doesn't NUL-terminate an overlong result. To make matters worse, it pads a short result with zeroes, which is a performance disaster if you have big buffers. strlcpy(), by contrast, is a mis-designed "fix" for strlcpy(), lacking the insane NUL padding, but having a differently broken return value which returns the original length of the source string. Which means that it will read characters past the count from the source buffer, and you have to trust the source to be properly terminated. It also makes error handling fragile, since the test for overflow is unnecessarily subtle. strscpy() avoids both these problems, guaranteeing the NUL termination (but not excessive padding) if the destination size wasn't zero, and making the overflow condition very obvious by returning -E2BIG. It also doesn't read past the size of the source, and can thus be used for untrusted source data too. So why did I waffle about this for so long? Every time we introduce a new-and-improved interface, people start doing these interminable series of trivial conversion patches. And every time that happens, somebody does some silly mistake, and the conversion patch to the improved interface actually makes things worse. Because the patch is mindnumbing and trivial, nobody has the attention span to look at it carefully, and it's usually done over large swatches of source code which means that not every conversion gets tested. So I'm pulling the strscpy() support because it *is* a better interface. But I will refuse to pull mindless conversion patches. Use this in places where it makes sense, but don't do trivial patches to fix things that aren't actually known to be broken. * 'strscpy' of git://git.kernel.org/pub/scm/linux/kernel/git/cmetcalf/linux-tile: tile: use global strscpy() rather than private copy string: provide strscpy() Make asm/word-at-a-time.h available on all architectures |

This patch makes sure that atomic_{read,set}() are at least {READ,WRITE}_ONCE(). We already had the 'requirement' that atomic_read() should use ACCESS_ONCE(), and most archs had this, but a few were lacking. All are now converted to use READ_ONCE().

Pull locking and atomic updates from Ingo Molnar: "Main changes in this cycle are: - Extend atomic primitives with coherent logic op primitives (atomic_{or,and,xor}()) and deprecate the old partial APIs (atomic_{set,clear}_mask()) The old ops were incoherent with incompatible signatures across architectures and with incomplete support.

mn10300/cevt-mn10300: Migrate to new 'set-state' interface
Migrate mn10300 driver to the new 'set-state' interface provided by clockevents core, the earlier 'set-mode' interface is marked obsolete now. This also enables us to implement callbacks for new states of clockevent devices, for example: ONESHOT_STOPPED. We weren't doing anything in the ->set_mode() callback. So, this patch doesn't provide any set-state callbacks.

arch/*/io.h: Add ioremap_uc() to all architectures
This adds ioremap_uc() only for architectures that do not include asm-generic.h/io.h as that already provides a default definition for them for both cases where you have CONFIG_MMU and you do not, and because of this, the number of architectures this patch address is less than the architectures that the ioremap_wt() patch addressed, "arch/*/io.h: Add ioremap_wt() to all architectures"). In order to reduce the number of architectures we have to modify by adding new architecture IO APIs we'll have to review the architectures in this patch, see why they can't add asm-generic.h/io.h or issues that would be created by doing so and then spread a consistent inclusion of this header towards the end of their own header. For instance arch/metag includes the asm-generic/io.h *before* the ioremap*() definitions, this should be the other way around but only once we have guard wrappers for the non-MMU case also for asm-generic/io.h.

PCI: Call pci_read_bridge_bases() from core instead of arch code
When we scan a PCI bus, we read PCI-PCI bridge window registers with pci_read_bridge_bases() so we can validate the resource hierarchy. Most architectures call pci_read_bridge_bases() from pcibios_fixup_bus(), but PCI-PCI bridges are not arch-specific, so this doesn't need to be in arch-specific code. Call pci_read_bridge_bases() directly from the PCI core instead of from arch code. For alpha and mips, we now call pci_read_bridge_bases() always; previously we only called it if PCI_PROBE_ONLY was set.

Make asm/word-at-a-time.h available on all architectures
Added the x86 implementation of word-at-a-time to the generic version, which previously only supported big-endian. Omitted the x86-specific load_unaligned_zeropad(), which in any case is also not present for the existing BE-only implementation of a word-at-a-time, and is only used under CONFIG_DCACHE_WORD_ACCESS. Added as a "generic-y" to the Kbuilds of all architectures that didn't previously have it. Signed-off-by: Chris Metcalf <cmetcalf@ezchip.com> |

This series of commits converts non-modular code that is using the module_init() call to hook itself into the system to instead use device_initcall(). The conversion is a runtime no-op, since module_init actually becomes __initcall in the non-modular case, and that in turn gets mapped onto device_initcall. A couple files show a larger negative diffstat, representing ones that had a module_exit function that we remove here vs previously relying on the linker to dispose of it. We make this conversion now, so that we can relocate module_init from init.h into module.h in the future. The files changed here are just limited to those that would otherwise have to add module.h to obviously non-modular code, in order to avoid a compile fail, as testing has shown" * tag 'module_init-device_initcall-v4.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: MIPS: don't use module_init in non-modular cobalt/mtd.c file drivers/leds: don't use module_init in non-modular leds-cobalt-raq.c cris: don't use module_init for non-modular core eeprom.c code tty/metag_da: Avoid module_init/module_exit in non-modular code drivers/clk: don't use module_init in clk-nomadik.c which is non-modular xtensa: don't use module_init for non-modular core network.c code sh: don't use module_init in non-modular psw.c code mn10300: don't use module_init in non-modular flash.c code parisc64: don't use module_init for non-modular core perf code parisc: don't use module_init for non-modular core pdc_cons code cris: don't use module_init for non-modular core intmem.c code ia64: don't use module_init in non-modular sim/simscsi.c code ia64: don't use module_init for non-modular core kernel/mca.c code arm: don't use module_init in non-modular mach-vexpress/spc.c code powerpc: don't use module_init in non-modular 83xx suspend code powerpc: use device_initcall for registering rtc devices x86: don't use module_init in non-modular devicetree.c code x86: don't use module_init in non-modular intel_mid_vrtc.c |
