2019-06-19KVM: x86: Modify struct kvm_nested_state to have explicit fields for dataLiran Alon2-22/+22
Improve the KVM_{GET,SET}_NESTED_STATE structs by detailing the format of VMX nested state data in a struct. In order to avoid changing the ioctl values of KVM_{GET,SET}_NESTED_STATE, there is a need to preserve sizeof(struct kvm_nested_state). This is done by defining the data struct as "data.vmx[0]". It was the most elegant way I found to preserve struct size while still keeping struct readable and easy to maintain. It does have a misfortunate side-effect that now it has to be accessed as "data.vmx[0]" rather than just "data.vmx". Because we are already modifying these structs, I also modified the following: * Define the "format" field values as macros. * Rename vmcs_pa to vmcs12_pa for better readability.

2019-06-18perf build: Handle slang being in /usr/include and in /usr/include/slang/Arnaldo Carvalho de Melo2-3/+13
In some distros slang.h may be in a /usr/include 'slang' subdir, so use the if slang is not explicitely disabled (by using NO_SLANG=1) and its feature test for the common case (having /usr/include/slang.h) failed, use the results for the test that checks if it is in slang/slang.h. Change the only file in perf that includes slang.h to use HAVE_SLANG_INCLUDE_SUBDIR and forget about this for good. On a rhel6 system now we have: $ /tmp/build/perf/perf -vv | grep slang libslang: [ on ] # HAVE_SLANG_SUPPORT $ ldd /tmp/build/perf/perf | grep libslang libslang.so.2 => /usr/lib64/libslang.so.2 (0x00007fa2d5a8d000) $ grep slang /tmp/build/perf/FEATURE-DUMP feature-libslang=0 feature-libslang-include-subdir=1 $ cat /etc/redhat-release CentOS release 6.10 (Final) $ While on fedora:29: $ /tmp/build/perf/perf -vv | grep slang libslang: [ on ] # HAVE_SLANG_SUPPORT $ ldd /tmp/build/perf/perf | grep slang libslang.so.2 => /lib64/libslang.so.2 (0x00007f8eb11a7000) $ grep slang /tmp/build/perf/FEATURE-DUMP feature-libslang=1 feature-libslang-include-subdir=1 $ $ cat /etc/fedora-release Fedora release 29 (Twenty Nine) $ The feature-libslang-include-subdir=1 line is because the 'gettid()' test was added to test-all.c as the new glibc has an implementation for that, so we soon should have it not failing, i.e. should be the common case soon.

2019-06-18tools build: Add test to check if slang.h is in /usr/include/slang/Arnaldo Carvalho de Melo3-1/+12
A few odd old distros (rhel5, 6, yeah, lots of those out in use, in many cases we want to use upstream perf on it) have the slang header files in /usr/include/slang/, so add a test that will be performed only when test-all.c (the one with the most common sane settings) fails, either because we're in one of these odd distros with slang/slang.h or because something else failed (say libelf is not present). So for the common case nothing changes, no additional test is performed. Next step is to check in perf the result of these tests.

2019-06-18libbpf: allow specifying map definitions using BTFAndrii Nakryiko2-9/+345
This patch adds support for a new way to define BPF maps. It relies on BTF to describe mandatory and optional attributes of a map, as well as captures type information of key and value naturally. This eliminates the need for BPF_ANNOTATE_KV_PAIR hack and ensures key/value sizes are always in sync with the key/value type. Relying on BTF, this approach allows for both forward and backward compatibility w.r.t. extending supported map definition features. By default, any unrecognized attributes are treated as an error, but it's possible relax this using MAPS_RELAX_COMPAT flag. New attributes, added in the future will need to be optional. The outline of the new map definition (short, BTF-defined maps) is as follows: 1. All the maps should be defined in .maps ELF section. It's possible to have both "legacy" map definitions in `maps` sections and BTF-defined maps in .maps sections. Everything will still work transparently. 2. The map declaration and initialization is done through a global/static variable of a struct type with few mandatory and extra optional fields: - type field is mandatory and specified type of BPF map; - key/value fields are mandatory and capture key/value type/size information; - max_entries attribute is optional; if max_entries is not specified or initialized, it has to be provided in runtime through libbpf API before loading bpf_object; - map_flags is optional and if not defined, will be assumed to be 0. 3. Key/value fields should be **a pointer** to a type describing key/value. The pointee type is assumed (and will be recorded as such and used for size determination) to be a type describing key/value of the map. This is done to save excessive amounts of space allocated in corresponding ELF sections for key/value of big size. 4. As some maps disallow having BTF type ID associated with key/value, it's possible to specify key/value size explicitly without associating BTF type ID with it. Use key_size and value_size fields to do that (see example below). Here's an example of simple ARRAY map defintion: struct my_value { int x, y, z; }; struct { int type; int max_entries; int *key; struct my_value *value; } btf_map SEC(".maps") = { .type = BPF_MAP_TYPE_ARRAY, .max_entries = 16, }; This will define BPF ARRAY map 'btf_map' with 16 elements. The key will be of type int and thus key size will be 4 bytes. The value is struct my_value of size 12 bytes. This map can be used from C code exactly the same as with existing maps defined through struct bpf_map_def. Here's an example of STACKMAP definition (which currently disallows BTF type IDs for key/value): struct { __u32 type; __u32 max_entries; __u32 map_flags; __u32 key_size; __u32 value_size; } stackmap SEC(".maps") = { .type = BPF_MAP_TYPE_STACK_TRACE, .max_entries = 128, .map_flags = BPF_F_STACK_BUILD_ID, .key_size = sizeof(__u32), .value_size = PERF_MAX_STACK_DEPTH * sizeof(struct bpf_stack_build_id), }; This approach is naturally extended to support map-in-map, by making a value field to be another struct that describes inner map. This feature is not implemented yet. It's also possible to incrementally add features like pinning with full backwards and forward compatibility. Support for static initialization of BPF_MAP_TYPE_PROG_ARRAY using pointers to BPF programs is also on the roadmap.

2019-06-18libbpf: split initialization and loading of BTFAndrii Nakryiko1-10/+24
Libbpf does sanitization of BTF before loading it into kernel, if kernel doesn't support some of newer BTF features. This removes some of the important information from BTF (e.g., DATASEC and VAR description), which will be used for map construction. This patch splits BTF processing into initialization step, in which BTF is initialized from ELF and all the original data is still preserved; and sanitization/loading step, which ensures that BTF is safe to load into kernel. This allows to use full BTF information to construct maps, while still loading valid BTF into older kernels.

2019-06-18libbpf: identify maps by section index in addition to offsetAndrii Nakryiko1-15/+25
To support maps to be defined in multiple sections, it's important to identify map not just by offset within its section, but section index as well. This patch adds tracking of section index. For global data, we record section index of corresponding .data/.bss/.rodata ELF section for uniformity, and thus don't need a special value of offset for those maps.

2019-06-18libbpf: refactor map initializationAndrii Nakryiko1-114/+133
User and global data maps initialization has gotten pretty complicated and unnecessarily convoluted. This patch splits out the logic for global data map and user-defined map initialization. It also removes the restriction of pre-calculating how many maps will be initialized, instead allowing to keep adding new maps as they are discovered, which will be used later for BTF-defined map definitions.

2019-06-17perf tools: Don't hardcode host include path for libslangFlorian Fainelli2-2/+1
Hardcoding /usr/include/slang is fundamentally incompatible with cross compilation and will lead to the inability for a cross-compiled environment to properly detect whether slang is available or not. If /usr/include/slang is necessary that is a distribution specific knowledge that could be solved with either a standard pkg-config .pc file (which slang has) or simply overriding CFLAGS accordingly, but the default perf Makefile should be clean of all of that.

2019-06-17perf trace: Fixup pointer arithmetic when consuming augmented syscall argsArnaldo Carvalho de Melo1-1/+1
We can't just add the consumed bytes to the arg->augmented.args member, as it is not void *, so it will access (consumed * sizeof(struct augmented_arg)) in the next augmented arg, totally wrong, cast the member to void pointe before adding the number of bytes consumed, duh. With this and hardcoding handling the 'renameat' and 'renameat2' syscalls in the tools/perf/examples/bpf/augmented_raw_syscalls.c eBPF proggie, we get: mv/24388 renameat2(AT_FDCWD, "/tmp/build/perf/util/.bpf-event.o.tmp", AT_FDCWD, "/tmp/build/perf/util/.bpf-event.o.cmd", RENAME_NOREPLACE) = 0 mv/24394 renameat2(AT_FDCWD, "/tmp/build/perf/util/.perf-hooks.o.tmp", AT_FDCWD, "/tmp/build/perf/util/.perf-hooks.o.cmd", RENAME_NOREPLACE) = 0 mv/24398 renameat2(AT_FDCWD, "/tmp/build/perf/util/.pmu-bison.o.tmp", AT_FDCWD, "/tmp/build/perf/util/.pmu-bison.o.cmd", RENAME_NOREPLACE) = 0 mv/24401 renameat2(AT_FDCWD, "/tmp/build/perf/util/.expr-bison.o.tmp", AT_FDCWD, "/tmp/build/perf/util/.expr-bison.o.cmd", RENAME_NOREPLACE) = 0 mv/24406 renameat2(AT_FDCWD, "/tmp/build/perf/util/.pmu.o.tmp", AT_FDCWD, "/tmp/build/perf/util/.pmu.o.cmd", RENAME_NOREPLACE) = 0 mv/24407 renameat2(AT_FDCWD, "/tmp/build/perf/util/.pmu-flex.o.tmp", AT_FDCWD, "/tmp/build/perf/util/.pmu-flex.o.cmd", RENAME_NOREPLACE) = 0 mv/24416 renameat2(AT_FDCWD, "/tmp/build/perf/util/.parse-events-flex.o.tmp", AT_FDCWD, "/tmp/build/perf/util/.parse-events-flex.o.cmd", RENAME_NOREPLACE) = 0 I.e. it works with two string args in the same syscall.
