2019-03-28tools headers: Update x86's syscall_64.tbl and uapi/asm-generic/unistdArnaldo Carvalho de Melo
To pick up the changes introduced in the following csets: 2b188cc1bb85 ("Add io_uring IO interface") edafccee56ff ("io_uring: add support for pre-mapped user IO buffers") 3eb39f47934f ("signal: add pidfd_send_signal() syscall") This makes 'perf trace' to become aware of these new syscalls, so that one can use them like 'perf trace -e ui_uring*,*signal' to do a system wide strace-like session looking at those syscalls, for instance. For example: # perf trace -s io_uring-cp ~acme/isos/RHEL-x86_64-dvd1.iso ~/bla Summary of events: io_uring-cp (383), 1208866 events, 100.0% syscall calls total min avg max stddev (msec) (msec) (msec) (msec) (%) -------------- ------ -------- ------ ------- ------- ------ io_uring_enter 605780 2955.615 0.000 0.005 33.804 1.94% openat 4 459.446 0.004 114.861 459.435 100.00% munmap 4 0.073 0.009 0.018 0.042 44.03% mmap 10 0.054 0.002 0.005 0.026 43.24% brk 28 0.038 0.001 0.001 0.003 7.51% io_uring_setup 1 0.030 0.030 0.030 0.030 0.00% mprotect 4 0.014 0.002 0.004 0.005 14.32% close 5 0.012 0.001 0.002 0.004 28.87% fstat 3 0.006 0.001 0.002 0.003 35.83% read 4 0.004 0.001 0.001 0.002 13.58% access 1 0.003 0.003 0.003 0.003 0.00% lseek 3 0.002 0.001 0.001 0.001 9.00% arch_prctl 2 0.002 0.001 0.001 0.001 0.69% execve 1 0.000 0.000 0.000 0.000 0.00% # # perf trace -e io_uring* -s io_uring-cp ~acme/isos/RHEL-x86_64-dvd1.iso ~/bla Summary of events: io_uring-cp (390), 1191250 events, 100.0% syscall calls total min avg max stddev (msec) (msec) (msec) (msec) (%) -------------- ------ -------- ------ ------ ------ ------ io_uring_enter 597093 2706.060 0.001 0.005 14.761 1.10% io_uring_setup 1 0.038 0.038 0.038 0.038 0.00% # More work needed to make the tools/perf/examples/bpf/augmented_raw_syscalls.c BPF program to copy the 'struct io_uring_params' arguments to perf's ring buffer so that 'perf trace' can use the BTF info put in place by pahole's conversion of the kernel DWARF and then auto-beautify those arguments.

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent Pull perf/core improvements and fixes from Arnaldo: kernel: Stephane Eranian : - Restore mmap record type correctly when handling PERF_RECORD_MMAP2 events, as the same template is used for all the threads interested in mmap events, some may want just PERF_RECORD_MMAP, while some may want the extra info in MMAP2 records. perf probe: Adrian Hunter: - Fix getting the kernel map, because since changes related to x86 PTI entry trampolines handling, there are more than one kernel map. perf script: Andi Kleen: - Support insn output for normal samples, i.e.: perf script -F ip,sym,insn --xed Will fetch the sample IP from the thread address space and feed it to Intel's XED disassembler, producing lines such as: ffffffffa4068804 native_write_msr wrmsr ffffffffa415b95e __hrtimer_next_event_base movq 0x18(%rax), %rdx That match 'perf annotate's output. - Make the --cpu filter apply to PERF_RECORD_COMM/FORK/... events, in addition to PERF_RECORD_SAMPLE. perf report: - Add a new --samples option to save a small random number of samples per hist entry, using a reservoir technique to select a representative number of samples. Then allow browsing the samples using 'perf script' as part of the hist entry context menu. This automatically adds the right filters, so only the thread or CPU of the sample is displayed. Then we use less' search functionality to directly jump to the time stamp of the selected sample. It uses different menus for assembler and source display. Assembler needs xed installed and source needs debuginfo. - Fix the UI browser scripts pop up menu when there are many scripts available. perf report: Andi Kleen: - Add 'time' sort option.

Vendor events: Martin Liška: - perf PMU events for AMD Family 17h. perf script python: Tony Jones: - Add python3 support for the remaining Intel PT related scripts, with these we should have a clean build of perf with python3 while still supporting the build with python2. libbpf: Arnaldo Carvalho de Melo: - Fix the build on uCLibc, adding the missing stdarg.h since we use va_list in one typedef.

2019-02-25libbpf: add support for using AF_XDP socketsMagnus Karlsson
This commit adds AF_XDP support to libbpf. The main reason for this is to facilitate writing applications that use AF_XDP by offering higher-level APIs that hide many of the details of the AF_XDP uapi. This is in the same vein as libbpf facilitates XDP adoption by offering easy-to-use higher level interfaces of XDP functionality. Hopefully this will facilitate adoption of AF_XDP, make applications using it simpler and smaller, and finally also make it possible for applications to benefit from optimizations in the AF_XDP user space access code. Previously, people just copied and pasted the code from the sample application into their application, which is not desirable. The interface is composed of two parts: * Low-level access interface to the four rings and the packet * High-level control plane interface for creating and setting up umems and af_xdp sockets as well as a simple XDP program.

The netfilter conflicts were rather simple overlapping changes. However, the cls_tcindex.c stuff was a bit more complex. On the 'net' side, Cong is fixing several races and memory leaks. Whilst on the 'net-next' side we have Vlad adding the rtnl-ness support. What I've decided to do, in order to resolve this, is revert the conversion over to using a workqueue that Cong did, bringing us back to pure RCU. I did it this way because I believe that either Cong's races don't apply with have Vlad did things, or Cong will have to implement the race fix slightly differently. Signed-off-by: David S.

2019-01-29x86/speculation: Add PR_SPEC_DISABLE_NOEXECWaiman Long
With the default SPEC_STORE_BYPASS_SECCOMP/SPEC_STORE_BYPASS_PRCTL mode, the TIF_SSBD bit will be inherited when a new task is fork'ed or cloned. It will also remain when a new program is execve'ed. Only certain class of applications (like Java) that can run on behalf of multiple users on a single thread will require disabling speculative store bypass for security purposes. Those applications will call prctl(2) at startup time to disable SSB. They won't rely on the fact the SSB might have been disabled. Other applications that don't need SSBD will just move on without checking if SSBD has been turned on or not. The fact that the TIF_SSBD is inherited across execve(2) boundary will cause performance of applications that don't need SSBD but their predecessors have SSBD on to be unwittingly impacted especially if they write to memory a lot. To remedy this problem, a new PR_SPEC_DISABLE_NOEXEC argument for the PR_SET_SPECULATION_CTRL option of prctl(2) is added to allow applications to specify that the SSBD feature bit on the task structure should be cleared whenever a new program is being execve'ed.

Daniel Borkmann says: ==================== pull-request: bpf-next 2019-01-29 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Teach verifier dead code removal, this also allows for optimizing / removing conditional branches around dead code and to shrink the resulting image. Code store constrained architectures like nfp would have hard time doing this at JIT level, from Jakub. 2) Add JMP32 instructions to BPF ISA in order to allow for optimizing code generation for 32-bit sub-registers. Evaluation shows that this can result in code reduction of ~5-20% compared to 64 bit-only code generation. Also add implementation for most JITs, from Jiong. 3) Add support for __int128 types in BTF which is also needed for vmlinux's BTF conversion to work, from Yonghong. 4) Add a new command to bpftool in order to dump a list of BPF-related parameters from the system or for a specific network device e.g. in terms of available prog/map types or helper functions, from Quentin. 5) Add AF_XDP sock_diag interface for querying sockets from user space which provides information about the RX/TX/fill/completion rings, umem, memory usage etc, from Björn. 6) Add skb context access for skb_shared_info->gso_segs field, from Eric. 7) Add support for testing flow dissector BPF programs by extending existing BPF_PROG_TEST_RUN infrastructure, from Stanislav. 8) Split BPF kselftest's test_verifier into various subgroups of tests in order better deal with merge conflicts in this area, from Jakub. 9) Add support for queue/stack manipulations in bpftool, from Stanislav. 10) Document BTF, from Yonghong. 11) Dump supported ELF section names in libbpf on program load failure, from Taeung. 12) Silence a false positive compiler warning in verifier's BTF handling, from Peter. 13) Fix help string in bpftool's feature probing, from Prashant. 14) Remove duplicate includes in BPF kselftests, from Yue. ==================== Signed-off-by: David S.
