sctp: fix strchange_flags name for Stream Change Event
As defined in rfc6525#section-6.1.3, SCTP_STREAM_CHANGE_DENIED
and SCTP_STREAM_CHANGE_FAILED should be used instead of
SCTP_ASSOC_CHANGE_DENIED and SCTP_ASSOC_CHANGE_FAILED.
To keep the compatibility, fix it by adding two macros.

RISC-V Patches for the 4.20 Merge Window, Part 2 v2
This tag contains the follow-on patches I'd like to target for the 4.20 merge window. I'm being somewhat conservative here, as while there are a few patches on the mailing list that were posted early in the merge window I'd like to let those bake for another round -- this was a fairly big release as far as RISC-V is concerened, and we need to walk before we can run. As far as the patches that made it go: * A patch to ignore offline CPUs when calculating AT_HWCAP. This should fix GDB on the HiFive unleashed, which has an embedded core for hart 0 which is exposed to Linux as an offline CPU. * A move of EM_RISCV to elf-em.h, which is where it should have been to begin with. * I've also removed the 64-bit divide routines. I know I'm not really playing by my own rules here because I posted the patches this morning, but since they shouldn't be in the kernel I think it's better to err on the side of going too fast here. I don't anticipate any more patch sets for the merge window. Changes since v1: * Use a consistent base to merge from so the history isn't a mess. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEAM520YNJYN/OiG3470yhUCzLq0EFAlvZ//ITHHBhbG1lckBk YWJiZWx0LmNvbQAKCRDvTKFQLMurQaOqEACpJTs19+1HFQ/YSB4P+drIImDq9XNF OFElcqe+R961BnyHJUA4WObl0Bl9bDqciYhelwdeb/0gYaOBG5IsmwAKxN9N2f9d m2/3eVUyiwMDKsc8Mrdcu7e3TLvfnhfaSOVe9hDvVcSeZvaC4S+dr+b7gjOZd45o 52SQqj6TMh20g5h6knaU5wnhHriJH7U4MwiEmwSTZuUkKj8Uoa1HGyzuVqqhi6A2 3y0m4VmVTwS9dmork2xZdsif+POSxrRxdtMTMWf85FelSO1OdTeMemUx2WnnWlCU 5VoPF5upXWB6uVtgXAVC8yhjCke5mUIOMcO10UGXdcjS/q9Vfg0yt6LusijTmYec UznnpnkPOap3t6tb+dkRanP+BRphB6A9DpXUkiGGo2nwbi48OC+pTYjZMdRUX7r3 FHq3LknprDfK6+D6goftlXlYSmb8H2rSCubK5dv6Zq9/rkBAkN/ESo9HEXvtPrAh oQAU1kmjq1EQg87fpmMvVySLApj+YPCoNMaPn3be03JRup4vaoGo8obmVP7rqgAG BIq6gx2BqqWWNvJftFm85AurTC1K3ClLO0mgTD5zhHvaCTHNI0TLlYh58QcKU00j c6+u+6tMF00Nvk8n/cbC/hRc2T+oAGb6hr6pFQEhANAkMu9dYpYfOWRbYl7Iiszq J3eT+7rxvHXCpg== =9Lsg -----END PGP SIGNATURE----- Merge tag 'riscv-for-linus-4.20-mw2' of git://git.kernel.org/pub/scm/linux/kernel/git/palmer/riscv-linux Pull more RISC-V updates from Palmer Dabbelt: "This contains the follow-on patches I'd like to target for the 4.20 merge window.

The latest versions of Google camera and codec HAL depends on such feature. At this stage, it supports only stateless codecs. It has been discussed for a long time (at least over the last 3-4 years), and we finally reached to something that seem to work. This series contain both the API and core changes required to support it and a new m2m decoder driver (cedrus). As the current API is still experimental, the only real driver using it (cedrus) was added at staging[1]. We intend to keep it there for a while, in order to test the API. Only when we're sure that this API works for other cases (like encoders), we'll move this driver out of staging and set the API into a stone. [1] We added support for the vivid virtual driver (used only for testing) to it too, as it makes easier to test the API for the ones that don't have the cedrus hardware" * tag 'media/v4.20-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (53 commits) media: dt-bindings: Document the Rockchip VPU bindings media: platform: Add Cedrus VPU decoder driver media: dt-bindings: media: Document bindings for the Cedrus VPU driver media: v4l: Add definition for the Sunxi tiled NV12 format media: v4l: Add definitions for MPEG-2 slice format and metadata media: videobuf2-core: Rework and rename helper for request buffer count media: v4l2-ctrls.c: initialize an error return code with zero media: v4l2-compat-ioctl32.c: add missing documentation for a field media: media-request: update documentation media: media-request: EPERM -> EACCES/EBUSY media: v4l2-ctrls: improve media_request_(un)lock_for_update media: v4l2-ctrls: use media_request_(un)lock_for_access media: media-request: add media_request_(un)lock_for_access media: vb2: set reqbufs/create_bufs capabilities media: videodev2.h: add new capabilities for buffer types media: buffer.rst: only set V4L2_BUF_FLAG_REQUEST_FD for QBUF media: v4l2-ctrls: return -EACCES if request wasn't completed media: media-request: return -EINVAL for invalid request_fds media: vivid: add request support media: vivid: add mc ... |

delayacct: track delays from thrashing cache pages
Delay accounting already measures the time a task spends in direct reclaim and waiting for swapin, but in low memory situations tasks spend can spend a significant amount of their time waiting on thrashing page cache. This isn't tracked right now. To know the full impact of memory contention on an individual task, measure the delay when waiting for a recently evicted active cache page to read back into memory. Also update tools/accounting/getdelays.c: [hannes@computer accounting]$ sudo ./getdelays -d -p 1 print delayacct stats ON PID 1 CPU count real total virtual total delay total delay average 50318 745000000 847346785 400533713 0.008ms IO count delay total delay average 435 122601218 0ms SWAP count delay total delay average 0 0 0ms RECLAIM count delay total delay average 0 0 0ms THRASHING count delay total delay average 19 12621439 0ms Link: http://lkml.kernel.org/r/20180828172258.3185-4-hannes@cmpxchg.org Signed-off-by: Johannes Weiner <hannes@cmpxchg.org> Acked-by: Peter Zijlstra (Intel) <peterz@infradead.org> Tested-by: Daniel Drake <drake@endlessm.com> Tested-by: Suren Baghdasaryan <surenb@google.com> Cc: Christopher Lameter <cl@linux.com> Cc: Ingo Molnar <mingo@redhat.com> Cc: Johannes Weiner <jweiner@fb.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Peter Enderborg <peter.enderborg@sony.com> Cc: Randy Dunlap <rdunlap@infradead.org> Cc: Shakeel Butt <shakeelb@google.com> Cc: Tejun Heo <tj@kernel.org> Cc: Vinayak Menon <vinmenon@codeaurora.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

libnvdimm for 4.20
* Improve the efficiency and performance of reading nvdimm-namespace labels. Reduce the amount of label data read at driver load time by a few orders of magnitude. Reduce heavyweight call-outs to platform-firmware routines. * Handle media errors located in the 'struct page' array stored on a persistent memory namespace. Let the kernel clear these errors rather than an awkward userspace workaround. * Fix Address Range Scrub (ARS) completion tracking. Correct occasions where the kernel indicates completion of ARS before submission. * Fix asynchronous device registration reference counting. * Add support for reporting an nvdimm dirty-shutdown-count via sysfs. * Fix various small libnvdimm core and uapi issues. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJb0NuwAAoJEB7SkWpmfYgCjUYP/1RK35zXBJSArGE3CUkap/zp exuqUzhisiE3RER13hNvC59AxXB9QuIbzuR5bzWm+Lawuuaozn3iL2oKn3Gy0inl yE3m/1Hx43FTkYdH86K9bpaXtRfymppJiR475jRFin17xWL3UP2JJgYtGwoRfO4p OL1aLcGo04Y1E2h6sVx97DjiwWN5uTaG9jCciZr2w+s5pg1seuEOJcAayp+6D0Tq i2hZvQ6nyxxF2WzGqRk3ABbRySpQ5o4b33I/jjOKEFwYoB8UiZQeLuL2WRr1ztfz jo+aalLJjZTOMgeWPIYSuV+U8vySVUwXpMhfrMGnIRm5BuE9JUlHrYkMLcLZJyei 2qgQ65mDmoViBVx0w5k2nUjP8Ju5lC7fZTaLU60vf+3FZvBbSTtmog2+P0xMLg17 AHebl9slzJPO4r/z4XY+n9Bk/qOz6sfWk07LugfNcMdeZriJKr7BUclZVZDYiPJA /Rtnd8XRu8hS5Kfj7wK2QD5sVklS5VQhho/zzBZHQcQkQBfRo6f6YQ83N/6yoTKD p6nel3uRMX2n8+EPyODYt9j0cF7JupWqlSpRKUORrdSz85gt4D6W578tkJCEOCm0 JOm5HdLlwIhlIcam/w0blLOr+a0sISS4cWR72Vc/lSZHoM8ouQiQC/lplpiAAWwI 7pSmlYEEbZRQCy6ZrlVy =0FtE -----END PGP SIGNATURE----- Merge tag 'libnvdimm-for-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm updates from Dan Williams: - Improve the efficiency and performance of reading nvdimm-namespace labels.

This is the bulk of GPIO changes for the v4.20 series:
Core changes: - A patch series from Hans Verkuil to make it possible to enable/disable IRQs on a GPIO line at runtime and drive GPIO lines as output without having to put/get them from scratch. The irqchip callbacks have been improved so that they can use only the fastpatch callbacks to enable/disable irqs like any normal irqchip, especially the gpiod_lock_as_irq() has been improved to be callable in fastpath context. A bunch of rework had to be done to achieve this but it is a big win since I never liked to restrict this to slowpath. The only call requireing slowpath was try_module_get() and this is kept at the .request_resources() slowpath callback. In the GPIO CEC driver this is a big win sine a single line is used for both outgoing and incoming traffic, and this needs to use IRQs for incoming traffic while actively driving the line for outgoing traffic. - Janusz Krzysztofik improved the GPIO array API to pass a "cookie" (struct gpio_array) and a bitmap for setting or getting multiple GPIO lines at once. This improvement orginated in a specific need to speed up an OMAP1 driver and has led to a much better API and real performance gains when the state of the array can be used to bypass a lot of checks and code when we want things to go really fast. The previous code would minimize the number of calls down to the driver callbacks assuming the CPU speed was orders of magnitude faster than the I/O latency, but this assumption was wrong on several platforms: what we needed to do was to profile and improve the speed on the hot path of the array functions and this change is now completed. - Clean out the painful and hard to grasp BNF experiments from the device tree bindings. Future approaches are looking into using JSON schema for this purpose. (Rob Herring is floating a patch series.) New drivers: - The RCAR driver now supports r8a774a1 (RZ/G2M). - Synopsys GPIO via CREGs driver. Major improvements: - Modernization of the EP93xx driver to use irqdomain and other contemporary concepts. - The ingenic driver has been merged into the Ingenic pin control driver and removed from the GPIO subsystem. - Debounce support in the ftgpio010 driver. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJbzdyOAAoJEEEQszewGV1zfYcP/0HBEAOPhHD/i5OQxfKs1msh mFT/t/IbTmRpCgbEv4CDx4Kc/InE0sUnQr1TL/1WvU6uObM6Ncxq5Z90MvyrgzYu BqQHq2k2tORvkVSNRxcfD/BAAoo1EerXts1kDhutvdKfepfS6DxpENwzvsFgkVlq 2jj1cdZztjv8A+9cspHDpQP+jDvl1VSc10nR5fRu1TttSpUwzRJaB30NBNXJmMJc 5KUr67lEbsQRPsBvFErU11bydPqhfT+pXmODcfIwS0EtATQ8WC5mkSb/Ooei0fvT oZ7uR3Os8tMf7isOKssEyFabKwhnfOEt6TBt9em0TfUtInOo0Dc7r8TfBcn57fyZ xg2R9DQEVRfac8bjhF/BI5KHuN9IMGDDvj6XApumQVliZbISRjMnh3jte6RpcV0A Ejqz8FeDY13qvEdOnW1EPpwmXdDVWiEAq0ebGLStKNls+/4gB2HmyxGUOzJf+og5 hujsxcJzGQqjCe0moeY/1d7vsy0ZjbHoS+p5fy79U212y2O7onEzFU92AX89bxKC rx2eCNmiZxCUy1nqu8edO62VnH6QdnqG3o+a4DJfCSHPvFM/E/NX9zHemZubQQ4I rYXNy4bL4tEG9cqWMfBxWrpiDZw7H6l8kXwdZG8IMyRU9BcKu96amgZ+jBXwzoaB JZelAAUWB9APghJYFr7o =YosT -----END PGP SIGNATURE----- Merge tag 'gpio-v4.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.20 series: Core changes: - A patch series from Hans Verkuil to make it possible to enable/disable IRQs on a GPIO line at runtime and drive GPIO lines as output without having to put/get them from scratch.

bpf: sk_msg program helper bpf_msg_push_data
This allows user to push data into a msg using sk_msg program types. The format is as follows, bpf_msg_push_data(msg, offset, len, flags) this will insert 'len' bytes at offset 'offset'. For example to prepend 10 bytes at the front of the message the user can, bpf_msg_push_data(msg, 0, 10, 0); This will invalidate data bounds so BPF user will have to then recheck data bounds after calling this. After this the msg size will have been updated and the user is free to write into the added bytes. We allow any offset/len as long as it is within the (data, data_end) range. However, a copy will be required if the ring is full and its possible for the helper to fail with ENOMEM or EINVAL errors which need to be handled by the BPF program. This can be used similar to XDP metadata to pass data between sk_msg layer and lower layers.

There is not a direct relationship between those functions and the current maps syscalls, hence a new MAP_LOOKUP_AND_DELETE_ELEM syscall is added, this is mapped to the pop operation in the queue/stack maps and it is still to implement in other kind of maps.

bpf: add queue and stack maps
Queue/stack maps implement a FIFO/LIFO data storage for ebpf programs. These maps support peek, pop and push operations that are exposed to eBPF programs through the new bpf_map[peek/pop/push] helpers. Those operations are exposed to userspace applications through the already existing syscalls in the following way: BPF_MAP_LOOKUP_ELEM -> peek BPF_MAP_LOOKUP_AND_DELETE_ELEM -> pop BPF_MAP_UPDATE_ELEM -> push Queue/stack maps are implemented using a buffer, tail and head indexes, hence BPF_F_NO_PREALLOC is not supported. As opposite to other maps, queue and stack do not use RCU for protecting maps values, the bpf_map[peek/pop] have a ARG_PTR_TO_UNINIT_MAP_VALUE argument that is a pointer to a memory zone where to save the value of a map. Basically the same as ARG_PTR_TO_UNINIT_MEM, but the size has not be passed as an extra argument. Our main motivation for implementing queue/stack maps was to keep track of a pool of elements, like network ports in a SNAT, however we forsee other use cases, like for exampling saving last N kernel events in a map and then analysing from userspace.

UAPI: ndctl: Fix g++-unsupported initialisation in headers
The following code in the linux/ndctl header file: static inline const char *nvdimm_bus_cmd_name(unsigned cmd) { static const char * const names[] = { [ND_CMD_ARS_CAP] = "ars_cap", [ND_CMD_ARS_START] = "ars_start", [ND_CMD_ARS_STATUS] = "ars_status", [ND_CMD_CLEAR_ERROR] = "clear_error", [ND_CMD_CALL] = "cmd_call", }; if (cmd < ARRAY_SIZE(names) && names[cmd]) return names[cmd]; return "unknown"; } is broken in a number of ways: (1) ARRAY_SIZE() is not generally defined. (2) g++ does not support "non-trivial" array initialisers fully yet. (3) Every file that calls this function will acquire a copy of names[]. The same goes for nvdimm_cmd_name(). Fix all three by converting to a switch statement where each case returns a string. That way if cmd is a constant, the compiler can trivially reduce it and, if not, the compiler can use a shared lookup table if it thinks that is more efficient. A better way would be to remove these functions and their arrays from the header entirely. Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com> |

kvm: x86: Introduce KVM_CAP_EXCEPTION_PAYLOAD
This is a per-VM capability which can be enabled by userspace so that the faulting linear address will be included with the information about a pending #PF in L2, and the "new DR6 bits" will be included with the information about a pending #DB in L2. With this capability enabled, the L1 hypervisor can now intercept #PF before CR2 is modified. Under VMX, the L1 hypervisor can now intercept #DB before DR6 and DR7 are modified. When userspace has enabled KVM_CAP_EXCEPTION_PAYLOAD, it should generally provide an appropriate payload when injecting a #PF or #DB exception via KVM_SET_VCPU_EVENTS. However, to support restoring old checkpoints, this payload is not required. Note that bit 16 of the "new DR6 bits" is set to indicate that a debug exception (#DB) or a breakpoint exception (#BP) occurred inside an RTM region while advanced debugging of RTM transactional regions was enabled. This is the reverse of DR6.RTM, which is cleared in this scenario. This capability also enables exception.pending in struct kvm_vcpu_events, which allows userspace to distinguish between pending and injected exceptions.

kvm/x86 : add coalesced pio support
Coalesced pio is based on coalesced mmio and can be used for some port like rtc port, pci-host config port and so on. Specially in case of rtc as coalesced pio, some versions of windows guest access rtc frequently because of rtc as system tick. guest access rtc like this: write register index to 0x70, then write or read data from 0x71. writing 0x70 port is just as index and do nothing else. So we can use coalesced pio to handle this scene to reduce VM-EXIT time. When starting and closing a virtual machine, it will access pci-host config port frequently. So setting these port as coalesced pio can reduce startup and shutdown time. without my patch, get the vm-exit time of accessing rtc 0x70 and piix 0xcf8 using perf tools: (guest OS : windows 7 64bit) IO Port Access Samples Samples% Time% Min Time Max Time Avg time 0x70:POUT 86 30.99% 74.59% 9us 29us 10.75us (+- 3.41%) 0xcf8:POUT 1119 2.60% 2.12% 2.79us 56.83us 3.41us (+- 2.23%) with my patch IO Port Access Samples Samples% Time% Min Time Max Time Avg time 0x70:POUT 106 32.02% 29.47% 0us 10us 1.57us (+- 7.38%) 0xcf8:POUT 1065 1.67% 0.28% 0.41us 65.44us 0.66us (+- 10.55%) Signed-off-by: Peng Hao <peng.hao2@zte.com.cn> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> |

FDDI: defza: Add support for DEC FDDIcontroller 700 TURBOchannel adapter
Add support for the DEC FDDIcontroller 700 (DEFZA), Digital Equipment Corporation's first-generation FDDI network interface adapter, made for TURBOchannel and based on a discrete version of what eventually became Motorola's widely used CAMEL chipset. The CAMEL chipset is present for example in the DEC FDDIcontroller TURBOchannel, EISA and PCI adapters (DEFTA/DEFEA/DEFPA) that we support with the `defxx' driver, however the host bus interface logic and the firmware API are different in the DEFZA and hence a separate driver is required. There isn't much to say about the driver except that it works, but there is one peculiarity to mention. The adapter implements two Tx/Rx queue pairs. Of these one pair is the usual network Tx/Rx queue pair, in this case used by the adapter to exchange frames with the ring, via the RMC (Ring Memory Controller) chip. The Tx queue is handled directly by the RMC chip and resides in onboard packet memory. The Rx queue is maintained via DMA in host memory by adapter's firmware copying received data stored by the RMC in onboard packet memory. The other pair is used to communicate SMT frames with adapter's firmware. Any SMT frame received from the RMC via the Rx queue must be queued back by the driver to the SMT Rx queue for the firmware to process. Similarly the firmware uses the SMT Tx queue to supply the driver with SMT frames that must be queued back to the Tx queue for the RMC to send to the ring. This solution was chosen because the designers ran out of PCB space and could not squeeze in more logic onto the board that would be required to handle this SMT frame traffic without the need to involve the driver, as with the later DEFTA/DEFEA/DEFPA adapters. Finally the driver does some Frame Control byte decoding, so to avoid magic numbers some macros are added to <linux/if_fddi.h>. Signed-off-by: Maciej W.

fuse: enable caching of symlinks
FUSE file reads are cached in the page cache, but symlink reads are not. This patch enables FUSE READLINK operations to be cached which can improve performance of some FUSE workloads. In particular, I'm working on a FUSE filesystem for access to source code and discovered that about a 10% improvement to build times is achieved with this patch (there are a lot of symlinks in the source tree).

Conflicts were easy to resolve using immediate context mostly, except the cls_u32.c one where I simply too the entire HEAD chunk. Signed-off-by: David S. Miller <davem@davemloft.net> |
