BACKPORT: bpf: add bpf_ktime_get_boot_ns()
On a device like a cellphone which is constantly suspending and resuming CLOCK_MONOTONIC is not particularly useful for keeping track of or reacting to external network events. Instead you want to use CLOCK_BOOTTIME. Hence add bpf_ktime_get_boot_ns() as a mirror of bpf_ktime_get_ns() based around CLOCK_BOOTTIME instead of CLOCK_MONOTONIC.

perf tools: Correct SNOOPX field offset
[ Upstream commit 39c0a53b114d0317e5c4e76b631f41d133af5cb0 ]
perf_event.h has macros that define the field offsets in the data_src
bitmask in perf records. The SNOOPX and REMOTE offsets were both 37.
These are distinct fields, and the bitfield layout in perf_mem_data_src
confirms that SNOOPX should be at offset 38.
Committer notes:
This was extracted from a larger patch that also contained kernel
changes.

tools/ chroot and using stuff in the kernel sources:

tools uapi: fix RISC-V 64-bit support
[ Upstream commit d0df00e30e4bf9bc27ddbd092ad683ff6121b360 ] The BPF library is not built on 64-bit RISC-V, as the BPF feature is not detected. Looking more in details, feature/test-bpf.c fails to build with the following error: | In file included from /tmp/linux-4.19.12/tools/include/uapi/asm/bitsperlong.h:17, | from /tmp/linux-4.19.12/tools/include/uapi/asm-generic/unistd.h:2, | from /usr/include/riscv64-linux-gnu/asm/unistd.h:1, | from test-bpf.c:2: | /tmp/linux-4.19.12/tools/include/asm-generic/bitsperlong.h:14:2: error: #error Inconsistent word size. Check asm/bitsperlong.h | #error Inconsistent word size. Check asm/bitsperlong.h | ^~~~~ The UAPI from the tools directory is missing RISC-V support, therefore bitsperlong.h from asm-generic is used, defaulting to 32 bits. Fix that by adding tools/arch/riscv/include/uapi/asm/bitsperlong.h as a copy of arch/riscv/include/uapi/asm/bitsperlong.h and by updating tools/include/uapi/asm/bitsperlong.h.

x86/speculation: Add prctl() control for indirect branch speculation
commit 9137bb27e60e554dab694eafa4cca241fa3a694f upstream Add the PR_SPEC_INDIRECT_BRANCH option for the PR_GET_SPECULATION_CTRL and PR_SET_SPECULATION_CTRL prctls to allow fine grained per task control of indirect branch speculation via STIBP and IBPB. Invocations: Check indirect branch speculation status with - prctl(PR_GET_SPECULATION_CTRL, PR_SPEC_INDIRECT_BRANCH, 0, 0, 0); Enable indirect branch speculation with - prctl(PR_SET_SPECULATION_CTRL, PR_SPEC_INDIRECT_BRANCH, PR_SPEC_ENABLE, 0, 0); Disable indirect branch speculation with - prctl(PR_SET_SPECULATION_CTRL, PR_SPEC_INDIRECT_BRANCH, PR_SPEC_DISABLE, 0, 0); Force disable indirect branch speculation with - prctl(PR_SET_SPECULATION_CTRL, PR_SPEC_INDIRECT_BRANCH, PR_SPEC_FORCE_DISABLE, 0, 0); See Documentation/userspace-api/spec_ctrl.rst.

Daniel Borkmann says:
====================
pull-request: bpf-next 2018-08-07
The following pull-request contains BPF updates for your *net-next* tree.
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.

"A set of fixes for perf:
Kernel side:
- Fix the hardcoded index of extra PCI devices on Broadwell which
caused a resource conflict and triggered warnings on CPU hotplug.
Tooling:
- Update the tools copy of several files, including perf_event.h,
powerpc's asm/unistd.h (new io_pgetevents syscall), bpf.h and x86's
memcpy_64.s (used in 'perf bench mem'), silencing the respective
warnings during the perf tools build.
