git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc updates from Michael Ellerman: "Notable changes: - A fix for a bug in our page table fragment allocator, where a page table page could be freed and reallocated for something else while still in use, leading to memory corruption etc. The fix reuses pt_mm in struct page (x86 only) for a powerpc only refcount. - Fixes to our pkey support. Several are user-visible changes, but bring us in to line with x86 behaviour and/or fix outright bugs. Thanks to Florian Weimer for reporting many of these. - A series to improve the hvc driver & related OPAL console code, which have been seen to cause hardlockups at times. The hvc driver changes in particular have been in linux-next for ~month. - Increase our MAX_PHYSMEM_BITS to 128TB when SPARSEMEM_VMEMMAP=y. - Remove Power8 DD1 and Power9 DD1 support, neither chip should be in use anywhere other than as a paper weight. - An optimised memcmp implementation using Power7-or-later VMX instructions - Support for barrier_nospec on some NXP CPUs. - Support for flushing the count cache on context switch on some IBM CPUs (controlled by firmware), as a Spectre v2 mitigation. - A series to enhance the information we print on unhandled signals to bring it into line with other arches, including showing the offending VMA and dumping the instructions around the fault.

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 v4.19 kernel cycle. I don't know if anything in particular stands out. Maybe the Aspeed coprocessor thing from Benji: Aspeed is doing baseboard management chips (BMC's) for servers etc. These Aspeed's are ARM processors that exist inside (I guess) Intel servers, and they are moving forward to using mainline Linux in those. This is one of the pieces of the puzzle to achive that. They are doing OpenBMC, it's pretty cool: https://lwn.net/Articles/683320/ Summary: Core changes: - Add a new API for explicitly naming GPIO consumers, when needed. - Don't let userspace set values on input lines. While we do not think anyone would do this crazy thing we better plug the hole before someone uses it and think it's a nifty feature. - Avoid calling chip->request() for unused GPIOs. New drivers/subdrivers: - The Mediatek MT7621 is supported which is a big win for OpenWRT and similar router distributions using this chip, as it seems every major router manufacturer on the planet has made products using this chip: https://wikidevi.com/wiki/MediaTek_MT7621 - The Tegra 194 is now supported. - The IT87 driver now supports IT8786E and IT8718F super-IO chips. - Add support for Rockchip RK3328 in the syscon GPIO driver. Driver changes: - Handle the get/set_multiple() properly on MMIO chips with inverted direction registers. We didn't have this problem until a new chip appear that has get/set registers AND inverted direction bits, OK now we handle it. - A patch series making more error codes percolate upward properly for different errors on gpiochip_lock_as_irq(). - Get/set multiple for the OMAP driver, accelerating these multiple line operations if possible. - A coprocessor interface for the Aspeed driver. Sometimes a few GPIO lines need to be grabbed by a co-processor for doing automated tasks, sometimes they are available as GPIO lines. By adding an explicit API in this driver we make it possible for the two line consumers to coexist. (This work was made available on the ib-aspeed branch, which may be appearing in other pull requests.) - Implemented .get_direction() and open drain in the SCH311x driver. - Continuing cleanup of included headers in GPIO drivers" * tag 'gpio-v4.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (80 commits) gpio: it87: Add support for IT8613 gpio: it87: add support for IT8718F Super I/O. gpiolib: Avoid calling chip->request() for unused gpios gpio: tegra: Include the right header gpio: mmio: Fix up inverted direction registers gpio: xilinx: Use the right include gpio: timberdale: Include the right header gpio: tb10x: Use the right include gpiolib: Fix of_node inconsistency gpio: vr41xx: Bail out on gpiochip_lock_as_irq() error gpio: uniphier: Bail out on gpiochip_lock_as_irq() error gpio: xgene-sb: Don't shadow error code of gpiochip_lock_as_irq() gpio: em: Don't shadow error code of gpiochip_lock_as_irq() gpio: dwapb: Don't shadow error code of gpiochip_lock_as_irq() gpio: bcm-kona: Don't shadow error code of gpiochip_lock_as_irq() gpiolib: Don't shadow error code of gpiochip_lock_as_irq() gpio: syscon: rockchip: add GRF GPIO support for rk3328 gpio: omap: Add get/set_multiple() callbacks gpio: pxa: remove set but not used variable 'gpio_offset' gpio-it87: add support for IT8786E Super I/O ...

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull RCU updates from Thomas Gleixner: "A large update to RCU: Preparatory work for consolidating the RCU flavors: - Introduce grace-period sequence numbers to the RCU-bh, RCU-preempt, and RCU-sched flavors, replacing the old ->gpnum and ->completed pair of fields. This change allows lockless code to obtain the complete grace-period state with a single READ_ONCE(), which is needed to maintain tolerable lock contention during the upcoming consolidation of the three RCU flavors. Note that grace-period sequence numbers are already used by rcu_barrier(), expedited RCU grace periods, and SRCU, and are thus already heavily used and well-tested. Joel Fernandes contributed a number of excellent fixes and improvements. - Clean up some grace-period-reporting loose ends, including improving the handling of quiescent states from offline CPUs and fixing some false-positive WARN_ON_ONCE() invocations. (Strictly speaking, the WARN_ON_ONCE() invocations were quite correct, but their invariants were (harmlessly) violated by the earlier sloppy handling of quiescent states from offline CPUs.) In addition, improve grace-period forward-progress guarantees so as to allow removal of fail-safe checks that required otherwise needless lock acquisitions.

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-08-13 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add driver XDP support for veth. This can be used in conjunction with redirect of another XDP program e.g. sitting on NIC so the xdp_frame can be forwarded to the peer veth directly without modification, from Toshiaki. 2) Add a new BPF map type REUSEPORT_SOCKARRAY and prog type SK_REUSEPORT in order to provide more control and visibility on where a SO_REUSEPORT sk should be located, and the latter enables to directly select a sk from the bpf map. This also enables map-in-map for application migration use cases, from Martin. 3) Add a new BPF helper bpf_skb_ancestor_cgroup_id() that returns the id of cgroup v2 that is the ancestor of the cgroup associated with the skb at the ancestor_level, from Andrey. 4) Implement BPF fs map pretty-print support based on BTF data for regular hash table and LRU map, from Yonghong. 5) Decouple the ability to attach BTF for a map from the key and value pretty-printer in BPF fs, and enable further support of BTF for maps for percpu and LPM trie, from Daniel. 6) Implement a better BPF sample of using XDP's CPU redirect feature for load balancing SKB processing to remote CPU. The sample implements the same XDP load balancing as Suricata does which is symmetric hash based on IP and L4 protocol, from Jesper. 7) Revert adding NULL pointer check with WARN_ON_ONCE() in __xdp_return()'s critical path as it is ensured that the allocator is present, from Björn. ==================== Signed-off-by: David S.

2018-08-13selftests/bpf: Selftest for bpf_skb_ancestor_cgroup_idAndrey Ignatov4-3/+302
Add selftests for bpf_skb_ancestor_cgroup_id helper. test_skb_cgroup_id.sh prepares testing interface and adds tc qdisc and filter for it using BPF object compiled from test_skb_cgroup_id_kern.c program. BPF program in test_skb_cgroup_id_kern.c gets ancestor cgroup id using the new helper at different levels of cgroup hierarchy that skb belongs to, including root level and non-existing level, and saves it to the map where the key is the level of corresponding cgroup and the value is its id. To trigger BPF program, user space program test_skb_cgroup_id_user is run. It adds itself into testing cgroup and sends UDP datagram to link-local multicast address of testing interface. Then it reads cgroup ids saved in kernel for different levels from the BPF map and compares them with those in user space. They must be equal for every level of ancestry. Example of run: # ./test_skb_cgroup_id.sh Wait for testing link-local IP to become available ... OK Note: 8 bytes struct bpf_elf_map fixup performed due to size mismatch!

2018-08-08selftests/powerpc: Kill child processes on SIGINTBreno Leitao1-6/+12
There are some powerpc selftests, as tm/tm-unavailable, that run for a long period (>120 seconds), and if it is interrupted, as pressing CRTL-C (SIGINT), the foreground process (harness) dies but the child process and threads continue to execute (with PPID = 1 now) in background. In this case, you'd think the whole test exited, but there are remaining threads and processes being executed in background. Sometimes these zombies processes are doing annoying things, as consuming the whole CPU or dumping things to STDOUT. This patch fixes this problem by attaching an empty signal handler to SIGINT in the harness process. This handler will interrupt (EINTR) the parent process waitpid() call, letting the code to follow through the normal flow, which will kill all the processes in the child process group. This patch also fixes a typo. Signed-off-by: Breno Leitao <leitao@debian.org> Signed-off-by: Gustavo Romero <gromero@linux.vnet.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>

The main changes are: 1) Add cgroup local storage for BPF programs, which provides a fast accessible memory for storing various per-cgroup data like number of transmitted packets, etc, from Roman. 2) Support bpf_get_socket_cookie() BPF helper in several more program types that have a full socket available, from Andrey. 3) Significantly improve the performance of perf events which are reported from BPF offload. Also convert a couple of BPF AF_XDP samples overto use libbpf, both from Jakub. 4) seg6local LWT provides the End.DT6 action, which allows to decapsulate an outer IPv6 header containing a Segment Routing Header. Adds this action now to the seg6local BPF interface, from Mathieu. 5) Do not mark dst register as unbounded in MOV64 instruction when both src and dst register are the same, from Arthur. 6) Define u_smp_rmb() and u_smp_wmb() to their respective barrier instructions on arm64 for the AF_XDP sample code, from Brian. 7) Convert the tcp_client.py and tcp_server.py BPF selftest scripts over from Python 2 to Python 3, from Jeremy. 8) Enable BTF build flags to the BPF sample code Makefile, from Taeung. 9) Remove an unnecessary rcu_read_lock() in run_lwt_bpf(), from Taehee. 10) Several improvements to the README.rst from the BPF documentation to make it more consistent with RST format, from Tobin. 11) Replace all occurrences of strerror() by calls to strerror_r() in libbpf and fix a FORTIFY_SOURCE build error along with it, from Thomas. 12) Fix a bug in bpftool's get_btf() function to correctly propagate an error via PTR_ERR(), from Yue. ==================== Signed-off-by: David S.

This adds a set of test cases to test the behaviour of copy_tofrom_user when exceptions are encountered accessing the source or destination. Currently, copy_tofrom_user does not always copy as many bytes as possible when an exception occurs on a store to the destination, and that is reflected in failures in these tests.
