2019-09-06ipc: fix semtimedop for generic 32-bit architecturesArnd Bergmann
As Vincent noticed, the y2038 conversion of semtimedop in linux-5.1 broke when commit 00bf25d693e7 ("y2038: use time32 syscall names on 32-bit") changed all system calls on all architectures that take a 32-bit time_t to point to the _time32 implementation, but left out semtimedop in the asm-generic header. This affects all 32-bit architectures using asm-generic/unistd.h: h8300, unicore32, openrisc, nios2, hexagon, c6x, arc, nds32 and csky. The notable exception is riscv32, which has dropped support for the time32 system calls entirely.

2019-09-06io_uring: expose single mmap capabilityJens Axboe
After commit 75b28affdd6a we can get by with just a single mmap to map both the sq and cq ring. However, userspace doesn't know that. Add a features variable to io_uring_params, and notify userspace that the kernel has this ability. This can then be used in liburing (or in applications directly) to avoid the second mmap.

Daniel Borkmann says: ==================== The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add the ability to use unaligned chunks in the AF_XDP umem. By relaxing where the chunks can be placed, it allows to use an arbitrary buffer size and place whenever there is a free address in the umem. Helps more seamless DPDK AF_XDP driver integration. Support for i40e, ixgbe and mlx5e, from Kevin and Maxim. 2) Addition of a wakeup flag for AF_XDP tx and fill rings so the application can wake up the kernel for rx/tx processing which avoids busy-spinning of the latter, useful when app and driver is located on the same core. Support for i40e, ixgbe and mlx5e, from Magnus and Maxim. 3) bpftool fixes for printf()-like functions so compiler can actually enforce checks, bpftool build system improvements for custom output directories, and addition of 'bpftool map freeze' command, from Quentin. 4) Support attaching/detaching XDP programs from 'bpftool net' command, from Daniel. 5) Automatic xskmap cleanup when AF_XDP socket is released, and several barrier/{read,write}_once fixes in AF_XDP code, from Björn. 6) Relicense of bpf_helpers.h/bpf_endian.h for future libbpf inclusion as well as libbpf versioning improvements, from Andrii. 7) Several new BPF kselftests for verifier precision tracking, from Alexei. 8) Several BPF kselftest fixes wrt endianess to run on s390x, from Ilya. 9) And more BPF kselftest improvements all over the place, from Stanislav. 10) Add simple BPF map op cache for nfp driver to batch dumps, from Jakub. 11) AF_XDP socket umem mapping improvements for 32bit archs, from Ivan. 12) Add BPF-to-BPF call and BTF line info support for s390x JIT, from Yauheni. 13) Small optimization in arm64 JIT to spare 1 insns for BPF_MOD, from Jerin. 14) Fix an error check in bpf_tcp_gen_syncookie() helper, from Petar. 15) Various minor fixes and cleanups, from Nathan, Masahiro, Masanari, Peter, Wei, Yue. ==================== Signed-off-by: David S.

2019-09-06net_sched: act_police: add 2 new attributes to support police 64bit rate and ↵David Dai
peakrate For high speed adapter like Mellanox CX-5 card, it can reach upto 100 Gbits per second bandwidth. Currently htb already supports 64bit rate in tc utility. However police action rate and peakrate are still limited to 32bit value (upto 32 Gbits per second). Add 2 new attributes TCA_POLICE_RATE64 and TCA_POLICE_RATE64 in kernel for 64bit support so that tc utility can use them for 64bit rate and peakrate value to break the 32bit limit, and still keep the backward binary compatibility.

2019-09-06net: openvswitch: Set OvS recirc_id from tc chain indexPaul Blakey
Offloaded OvS datapath rules are translated one to one to tc rules, for example the following simplified OvS rule: recirc_id(0),in_port(dev1),eth_type(0x0800),ct_state(-trk) actions:ct(),recirc(2) Will be translated to the following tc rule: $ tc filter add dev dev1 ingress \ prio 1 chain 0 proto ip \ flower tcp ct_state -trk \ action ct pipe \ action goto chain 2 Received packets will first travel though tc, and if they aren't stolen by it, like in the above rule, they will continue to OvS datapath. Since we already did some actions (action ct in this case) which might modify the packets, and updated action stats, we would like to continue the proccessing with the correct recirc_id in OvS (here recirc_id(2)) where we left off. To support this, introduce a new skb extension for tc, which will be used for translating tc chain to ovs recirc_id to handle these miss cases. Last tc chain index will be set by tc goto chain action and read by OvS datapath.

2019-09-04tty: serial: Add linflexuart driver for S32V234Stefan-gabriel Mirea
Introduce support for LINFlex driver, based on: - the version of Freescale LPUART driver after commit b3e3bf2ef2c7 ("Merge 4.0-rc7 into tty-next"); - commit abf1e0a98083 ("tty: serial: fsl_lpuart: lock port on console write"). In this basic version, the driver can be tested using initramfs and relies on the clocks and pin muxing set up by U-Boot. Remarks concerning the earlycon support: - LinFlexD does not allow character transmissions in the INIT mode (see section 47.4.2.1 in the reference manual[1]). Therefore, a mutual exclusion between the first linflex_setup_watermark/linflex_set_termios executions and linflex_earlycon_putchar was employed and the characters normally sent to earlycon during initialization are kept in a buffer and sent afterwards. - Empirically, character transmission is also forbidden within the last 1-2 ms before entering the INIT mode, so we use an explicit timeout (PREINIT_DELAY) between linflex_earlycon_putchar and the first call to linflex_setup_watermark. - U-Boot currently uses the UART FIFO mode, while this driver makes the transition to the buffer mode. Therefore, the earlycon putchar function matches the U-Boot behavior before initializations and the Linux behavior after.

2019-08-31xsk: add support to allow unaligned chunk placementKevin Laatz
Currently, addresses are chunk size aligned. This means, we are very restricted in terms of where we can place chunk within the umem. For example, if we have a chunk size of 2k, then our chunks can only be placed at 0,2k,4k,6k,8k... and so on (ie. every 2k starting from 0). This patch introduces the ability to use unaligned chunks. With these changes, we are no longer bound to having to place chunks at a 2k (or whatever your chunk size is) interval. Since we are no longer dealing with aligned chunks, they can now cross page boundaries. Checks for page contiguity have been added in order to keep track of which pages are followed by a physically contiguous page.

2019-08-28perf: Allow normal events to output AUX dataAlexander Shishkin
In some cases, ordinary (non-AUX) events can generate data for AUX events. For example, PEBS events can come out as records in the Intel PT stream instead of their usual DS records, if configured to do so. One requirement for such events is to consistently schedule together, to ensure that the data from the "AUX output" events isn't lost while their corresponding AUX event is not scheduled. We use grouping to provide this guarantee: an "AUX output" event can be added to a group where an AUX event is a group leader, and provided that the former supports writing to the latter.

This patch introduces meta matches in the kernel for time (a UNIX timestamp), day (a day of week, represented as an integer between 0-6), and hour (an hour in the current day, or: number of seconds since midnight). All values are taken as unsigned 64-bit integers. The 'time' keyword is internally converted to nanoseconds by nft in userspace, and hence the timestamp is taken in nanoseconds as well.

2019-08-24erofs: move erofs out of stagingGao Xiang
EROFS filesystem has been merged into linux-staging for a year. EROFS is designed to be a better solution of saving extra storage space with guaranteed end-to-end performance for read-only files with the help of reduced metadata, fixed-sized output compression and decompression inplace technologies. In the past year, EROFS was greatly improved by many people as a staging driver, self-tested, betaed by a large number of our internal users, successfully applied to almost all in-service HUAWEI smartphones as the part of EMUI 9.1 and proven to be stable enough to be moved out of staging. EROFS is a self-contained filesystem driver. Although there are still some TODOs to be more generic, we have a dedicated team actively keeping on working on EROFS in order to make it better with the evolution of Linux kernel as the other in-kernel filesystems. As Pavel suggested, it's better to do as one commit since git can do moves and all histories will be saved in this way. Let's promote it from staging and enhance it more actively as a "real" part of kernel for more wider scenarios!

2019-08-23drop_monitor: Make timestamps y2038 safeIdo Schimmel
Timestamps are currently communicated to user space as 'struct timespec', which is not considered y2038 safe since it uses a 32-bit signed value for seconds. Fix this while the API is still not part of any official kernel release by using 64-bit nanoseconds timestamps instead.

2019-08-22jffs2: Remove C++ style comments from uapi headerMasahiro Yamada
Linux kernel tolerates C++ style comments these days. Actually, the SPDX License tags for .c files start with //. On the other hand, uapi headers are written in more strict C, where the C++ comment style is forbidden. I simply dropped these lines instead of fixing the comment style. This code has been always commented out since it was added around Linux 2.4.9 (i.e. commented out for more than 17 years). 'Maybe later...' will never happen.

2019-08-21bpf: clarify when bpf_trace_printk discards linesPeter Wu
I opened /sys/kernel/tracing/trace once and kept reading from it. bpf_trace_printk somehow did not seem to work, no entries were appended to that trace file. It turns out that tracing is disabled when that file is open. Save the next person some time and document this. The trace file is described in Documentation/trace/ftrace.rst, however the implication "tracing is disabled" did not immediate translate to "bpf_trace_printk silently discards entries".

2019-08-21nl80211: Add support for EDMG channelsAlexei Avshalom Lazar
802.11ay specification defines Enhanced Directional Multi-Gigabit (EDMG) STA and AP which allow channel bonding of 2 channels and more. Introduce new NL attributes that are needed for enabling and configuring EDMG support. Two new attributes are used by kernel to publish driver's EDMG capabilities to the userspace: NL80211_BAND_ATTR_EDMG_CHANNELS - bitmap field that indicates the 2.16 GHz channel(s) that are supported by the driver. When this attribute is not set it means driver does not support EDMG. NL80211_BAND_ATTR_EDMG_BW_CONFIG - represent the channel bandwidth configurations supported by the driver. Additional two new attributes are used by the userspace for connect command and for AP configuration: NL80211_ATTR_WIPHY_EDMG_CHANNELS NL80211_ATTR_WIPHY_EDMG_BW_CONFIG New rate info flag - RATE_INFO_FLAGS_EDMG, can be reported from driver and used for bitrate calculation that will take into account EDMG according to the 802.11ay specification.
