Lazily symbolize regular ELF binaries This patch adds a new API to bcc_elf.h, bcc_elf_foreach_sym_lazy. This helper avoids storing symbol names in string format, as for large binaries this data can get quite large. Instead we store the location in the ELF binary where we can later find the string. Later on, we can load these strings on demand and cache them in case they're accessed again. This patch also makes lazy resolution the default for regular ELF binaries, where regular means not perfmap or VDSO. --- src/cc/bcc_elf.c | 59 +++++++++++++++++++++++++++++++++++++++------- src/cc/bcc_elf.h | 9 +++++++ src/cc/bcc_syms.cc | 20 +++++++++++++++- src/cc/syms.h | 19 ++++++++++++++- 4 files changed, 97 insertions(+), 10 deletions(-) diff --git a/src/cc/bcc_elf.c b/src/cc/bcc_elf.c index b9d25d84f..3f99fbf31 100644 --- a/src/cc/bcc_elf.c +++ b/src/cc/bcc_elf.c @@ -214,7 +214,8 @@ static Elf_Scn * get_section(Elf *e, const char *section_name, static int list_in_scn(Elf *e, Elf_Scn *section, size_t stridx, size_t symsize, struct bcc_symbol_option *option, - bcc_elf_symcb callback, void *payload) { + bcc_elf_symcb callback, bcc_elf_symcb_lazy callback_lazy, + void *payload) { Elf_Data *data = NULL;

I assume the exit() that has been added in the keyboard interrupt handler is there so that no output is displayed when the program has been interrupted early when a time limit has been specified. But since the tool still invite the user to use Ctrl-C to end the tracing in that case, it seems more consistent to show an output in that case too.

Symfs is a file path prefix that needs to be prepended to full path of a library to compute location of corresponding debuginfo. It will allow bcc users to provide debug symbols if only they can write to at least one directory. Nothing else needs to be assumed regarding the system bcc runs on. My intention is to make debuginfo lookup work on Android in one form or another. None of the gdb rules works out of the box: - native libraries are often managed by Android apps themselves and uncompressed by apps into private directories. Sideloading debuginfo into those directories might be not feasible. What's more it's desirable to remove data like debuglink from release builds of mobile apps. At the same time those builds are the most interesting ones to investigate with bcc. - there is no /usr directory on Android, so there is no /usr/lib/debug/. It could be created with some effort, but symfs is much more convenient and already used when profiling with simpleperf (fork of perf for Android). --- src/cc/bcc_elf.c | 60 ++++++++++++++++++++++++++++++++++++++++++++---- 1 file changed, 56 insertions(+), 4 deletions(-) diff --git a/src/cc/bcc_elf.c b/src/cc/bcc_elf.c index 65e0e53c2..584257199 100644 --- a/src/cc/bcc_elf.c +++ b/src/cc/bcc_elf.c @@ -546,6 +546,54 @@ static char *find_debug_via_buildid(Elf *e) { return NULL; } +static char *find_debug_via_symfs(Elf *e, const char* path) { + char fullpath[PATH_MAX]; + char buildid[128]; + char symfs_buildid[128]; + int check_build_id; + char *symfs; + Elf *symfs_e = NULL; + int symfs_fd = -1; + char *result = NULL; + + symfs = getenv("BCC_SYMFS"); + if (!symfs || !*symfs) + goto out; + + check_build_id = find_buildid(e, buildid); + + snprintf(fullpath, sizeof(fullpath), "%s/%s", symfs, path); + if (access(fullpath, F_OK) == -1) + goto out; + + if (openelf(fullpath, &symfs_e, &symfs_fd) < 0) { + symfs_e = NULL; + symfs_fd = -1; + goto out; + } + + if (check_build_id) { + if (!find_buildid(symfs_e, symfs_buildid)) + goto out; + + if (strncmp(buildid, symfs_buildid, sizeof(buildid))) + goto out; + } + + result = strdup(fullpath); + +out: + if (symfs_e) { + elf_end(symfs_e); + } + + if (symfs_fd != -1) { + close(symfs_fd); + } + + return result; +} + static int foreach_sym_core(const char *path, bcc_elf_symcb callback, bcc_elf_symcb_lazy callback_lazy, struct bcc_symbol_option *option, void *payload, @@ -561,13 +609,17 @@ static int foreach_sym_core(const char *path, bcc_elf_symcb callback, return -1; // If there is a separate debuginfo file, try to locate and read it, first - // using the build-id section, then using the debuglink section.

The trace.py updated the `__cgroup` map with user provided cgroup path information before attaching bpf functions to events for probe function(s).

This has caught surprise from many users. So, the commit https://github.com/iovisor/bcc/commit/ba64f031f2435aad5a85f8f37dbbe2a982cbbe6b attempts to remove the early return in map.lookup_or_init(). But then since NULL pointer could be returned, user will need to change their bpf program to check return value, otherwise, verifier will reject the program. As described in the above, such an API behavior change may cause verifier failure and reject previously loadable bpf programs. bcc should try to maintain API stability, esp. to avoid subtle API behavior change. This patch propose to restore the behavior of map.lookup_or_init() and introduce a new one map.lookup_or_try_init(), which will avoid unexpected return. The name is suggested by Alexei to reflect that init may fail. map.lookup_or_try_init() will be formally documented and used in bcc. A warning will be generated if map.lookup_or_init() is used.

The compilation needs to define CMAKE_USE_LIBBPF_PACKAGE variable to enable search for libbpf package. If the package is found it is used to build all the bcc libs. The libbcc.so and libbcc_bpf.so (and their static versions) remain the same. The new library libbcc-no-libbpf.so is built from all libcc.so sources including libbpf_bcc.so's sources: libbpf.c perf_reader.c and dynamically linked to libbpf.so library. With libbcc-no-libbpf.so symbols are versioned, so there's no chance of being mixed: Symbols exported from libbpf.so: $ objdump -T /usr/lib64/libbpf.so | grep bpf_map_lookup_elem 0000000000006df0 g DF .text 000000000000006e LIBBPF_0.0.1 bpf_map_lookup_elem 0000000000006e60 g DF .text 0000000000000076 LIBBPF_0.0.2 bpf_map_lookup_elem_flags Symbol needed by libbcc-no-libbpf.so: $ objdump -T /opt/bcc/lib64/libbcc-no-libbpf.so | grep bpf_map_lookup_elem 0000000000000000 DF *UND* 0000000000000000 LIBBPF_0.0.1 bpf_map_lookup_elem Symbols exported by current libbcc.so: $ objdump -T /opt/bcc/lib64/libbcc.so | grep bpf_map_lookup_elem 00000000023ad843 g DF .text 0000000000000082 Base bpf_map_lookup_elem_flags 00000000023ad7d3 g DF .text 0000000000000070 Base bpf_map_lookup_elem Besides that it's better to share common source of libbpf code, it also prevents issues when having application that links to libbpf and libbcc, where you could end up conflicting functions and segfaults if those 2 libbpf libs are not on the same version.

Two new constructs below are introduced to bpf program: BPF_HASH_OF_MAPS(map_name, "inner_map_name", max_entries) BPF_ARRAY_OF_MAPS(map_name, "inner_map_name", max_entries) In the above, "inner_map_name" is for metadata purpose and there must be a map defined in bpf program with map name "inner_map_name". Both python and C++ APIs are added. For python, a new Table API get_fd() is introduced to get the fd of a map so that the fd can be used by a map-in-map do update. The get_fd() is already exposed as API function in C++. For C++, without get_fd(), we will need to templatize basic functions like update_value etc, which I feed too heavy weight. Because of C++ using get_fd() mechanism, so I exposed similar API on python side for parity reason. For map-in-map, the inner map lookup/update/delete won't have explicit map names. Considering map-in-map is not used very frequently, I feel looking primitive bpf_map_{lookup,update,delete}_elem() probably okay, so I did not create any new bcc specific constructs for this purpose. Added both C++ and python test cases to show how to use the above two new map type in bcc.

However It turned on that using debugsource (in Fedora) package is not suitable or even possible, so we are switching to use the libbpf-static package instead. Adding libbpf-static package detection and removing source package detection. Using ar to extract objects from archive and linking them with both libbcc_bpf.so and libbcc_bpf.a. Using always uapi headers from the latest libbpf Github repo, because there are not packaged, but they are backwards compatible, so it's no problem to have older libbpf package with newer uapi headers.

There are some other efforts trying to get user lock stats by tracing e.g. pthread locking primitives. For example, Sasha Goldshtein's linux-tracing-workshop https://github.com/goldshtn/linux-tracing-workshop is referenced in bcc/docs/tutorial_bcc_python_developer.md. It has a tool called lockstat.py which traces pthread_mutex_init to collect some lock statistics for userspace locks. In bcc, in the past, we also had an effort to gather userspace lock statistics with the same name lockstat.py. https://github.com/iovisor/bcc/pull/1268 In the future, bcc could have a lockstat tool tracing userspace locks. So let us rename the current lockstat.py to klockstat.py to clearly express its scope. --- README.md | 2 +- man/man8/{lockstat.8 => klockstat.8} | 30 +++++++++---------- snapcraft/snapcraft.yaml | 4 +-- tests/python/test_tools_smoke.py | 4 +-- tools/{lockstat.py => klockstat.py} | 26 ++++++++-------- ...stat_example.txt => klockstat_example.txt} | 18 +++++------ 6 files changed, 42 insertions(+), 42 deletions(-) rename man/man8/{lockstat.8 => klockstat.8} (90%) rename tools/{lockstat.py => klockstat.py} (93%) rename tools/{lockstat_example.txt => klockstat_example.txt} (96%) diff --git a/README.md b/README.md index 8ff346413..90896113f 100644 --- a/README.md +++ b/README.md @@ -118,7 +118,7 @@ pair of .c and .py files, and some are directories of files. - tools/[hardirqs](tools/hardirqs.py): Measure hard IRQ (hard interrupt) event time.

Examples of commands: # opensnoop --cgroupmap /sys/fs/bpf/test01 # execsnoop --cgroupmap /sys/fs/bpf/test01 Cgroup ids can be discovered in userspace by the system call name_to_handle_at(); an example of C program doing that is available in examples/cgroupid/cgroupid.c. More complete documentation is added in docs/filtering_by_cgroups.md The documentation is independent from Kubernetes. However, my goal is to use this feature in Kubernetes: I am preparing to use this in Inspektor Gadget to select specific Kubernetes pods, depending on a Kubernetes label selector. Kubernetes pods matching the label selector can come and go during the execution of the bcc tools; Inspektor Gadget is updating the BPF hash map used by the bcc tools accordingly. --- .gitignore | 1 + docs/filtering_by_cgroups.md | 65 ++++++++++++++++++++++ examples/cgroupid/Dockerfile | 16 ++++++ examples/cgroupid/Makefile | 2 + examples/cgroupid/cgroupid.c | 101 +++++++++++++++++++++++++++++++++++ tools/execsnoop.py | 25 +++++++++ tools/execsnoop_example.txt | 9 ++++ tools/opensnoop.py | 17 ++++++ tools/opensnoop_example.txt | 8 +++ 9 files changed, 244 insertions(+) create mode 100644 docs/filtering_by_cgroups.md create mode 100644 examples/cgroupid/Dockerfile create mode 100644 examples/cgroupid/Makefile create mode 100644 examples/cgroupid/cgroupid.c diff --git a/.gitignore b/.gitignore index 65a3946c5..9218b70c4 100644 --- a/.gitignore +++ b/.gitignore @@ -10,3 +10,4 @@ cmake-build-debug debian/**/*.log obj-x86_64-linux-gnu +examples/cgroupid/cgroupid diff --git a/docs/filtering_by_cgroups.md b/docs/filtering_by_cgroups.md new file mode 100644 index 000000000..1c711a240 --- /dev/null +++ b/docs/filtering_by_cgroups.md @@ -0,0 +1,65 @@ +# Demonstrations of filtering by cgroups + +Some tools have an option to filter by cgroup by referencing a pinned BPF hash +map managed externally. + +Examples of commands: + +``` +# ./opensnoop --cgroupmap /sys/fs/bpf/test01 +# ./execsnoop --cgroupmap /sys/fs/bpf/test01 +``` + +The commands above will only display results from processes that belong to one +of the cgroups whose id, returned by `bpf_get_current_cgroup_id()`, is in the +pinned BPF hash map. + +The BPF hash map can be created by: + +``` +# bpftool map create /sys/fs/bpf/test01 type hash key 8 value 8 entries 128 \ + name cgroupset flags 0 +``` + +To get a shell in a new cgroup, you can use: + +``` +# systemd-run --pty --unit test bash +``` + +The shell will be running in the cgroup +`/sys/fs/cgroup/unified/system.slice/test.service`. + +The cgroup id can be discovered using the `name_to_handle_at()` system call.

In ProbeChecker, however, nb_derefs has a different meaning: it counts the number of dereferences encountered. This difference resulted in an error when ProbeChecker is traversing the right-hand side of an assignment. This commit fixes the error and adds tests for the two cases of assignments: when the right-hand side is an external pointer with several indirection levels and when it is a call to a function returning an external pointer with several indirection levels. This commit also changes ProbeSetter and assignsExtPtr to count dereferences instead of addrof in an effort to use nb_derefs more consistently across the code to mean "number of dereferences needed to get to the external pointer".

This also deletes the dead code for namespace handling in libbpf, as this was the last use of it.

Tests run inside docker, in an ubuntu 19.04 container base. For the github workflow: - The test_libbcc suite is run first, to potentially fail fast on these faster unit tests. - The Python test suite is run Some of these tests are allowed to fail, but the failure is still reported: - In catch2 tests, using the [!mayfail] tag, where this will be displayed in the test summary - In Python unittests, using the `@mayFail("Reason")` decorator, which is introduce for consistency with catch2. These will report the reason for the failure, and log this to an artifact of the test. --- .github/workflows/bcc-test.yml | 94 +++++++++++++++++++++++++++++++ .gitignore | 1 + Dockerfile.tests | 69

BPF's 'cleanup' is registered to be invoked atexit. Alas, commit 115b959d86 introduced an 'os.close(fn.fd)' call for each func loaded (to prevent accidental FD leakage). Problem is, that the 'self.funcs' dict entries are NOT deleted, making subsequent calls to 'cleanup' to attempt closing the same 'fn.fd' again and again. It is expected from 'cleanup' to operate correctly when called repeatedly; Therefore, it should "nullify" references to closed resources.

Corresponding llvm bug: https://bugs.llvm.org/show_bug.cgi?id=41918. If the element type is array type, the rewriter may generate code like addr = ({ typeof(__u8 [16]) _val; __builtin_memset(&_val, 0, sizeof(_val)); bpf_probe_read(&_val, sizeof(_val), (u64)&daddr->s6_addr); _val; }) for something like addr = daddr->s6_addr; where s6_addr is an array. The above code has an issue then as addr is pointing to some data which is out of scope, which meaning compiler is free to use the space.

The issue exposed an issue that to rewrite CODE1: __u8 byte = daddr->s6_addr[4]; will segfault and to rewrite CODE2: __u8 byte = (daddr->s6_addr)[4]; will be okay. For CODE1, the clang did not give enough information to find the text which contains the left bracket "[", given base "daddr->s6_addr" and subscript "4". For CODE2, the clang is able to get the information successfuly. I think if we really go inside the base "daddr->s6_addr" and gets to its member field "s6_addr", we can find the needed information for the text range containing "[". Let us fix the segfault first and if really desirable, we can try to enhance later for CODE1 patterns.

Subject: [PATCH 0227/1261] tools: add libbpf-based tools to BCC w/ runqslower as first converted tool Add runqslower as a first tool converted from BCC to libbpf, utilizing BPF CO-RE (Compile Once -

This will build all the listed +tools/applications. All the build artifacts, by default, go into .output +subdirectory to keep source code and build artifacts completely separate. The +only exception is resulting tool binaries, which are put in a current +directory. `make clean` will clean up all the build artifacts, including +generated binaries. + +Given libbpf package might not be available across wide variety of +distributions, all libbpf-based tools are linked statically against version of +libbpf that BCC links against (from submodule under src/cc/libbpf). This +results in binaries with minimal amount of dependencies (libc, libelf, and +libz are linked dynamically, though, given their widespread availability). + +Tools are expected to follow a simple naming convention: + - .c contains userspace C code of a tool. + - .bpf.c contains BPF C code, which gets compiled into BPF ELF file. + This ELF file is used to generate BPF skeleton .skel.h, which is + subsequently is included from .c. + - .h can optionally contain any types and constants, shared by both + BPF and userspace sides of a tool. + +For such cases, simply adding name to Makefile's APPS variable will +ensure this tool is built alongside others. + +For more complicated applications, some extra Makefile rules might need to be +created. For such cases, it is advised to put application into a dedicated +subdirectory and link it from main Makefile. + +vmlinux.h generation +------------------- + +vmlinux.h contains all kernel types, both exported and internal-only. BPF +CO-RE-based applications are expected to include this file in their BPF +program C source code to avoid dependency on kernel headers package. + +For more reproducible builds, vmlinux.h header file is pre-generated and +checked in along the other sources. This is done to avoid dependency on +specific user/build server's kernel configuration, because vmlinux.h +generation depends on having a kernel with BTF type information built-in +(which is enabled by `CONFIG_DEBUG_INFO_BTF=y` Kconfig option). + +vmlinux.h is generated from upstream Linux version at particular minor +version tag. E.g., `vmlinux_505.h` is generated from v5.5 tag. Exact set of +types available in compiled kernel depends on configuration used to compile +it. To generate present vmlinux.h header, default configuration was used, with +only extra `CONFIG_DEBUG_INFO_BTF=y` option enabled. + +Given different kernel version can have incompatible type definitions, it +might be important to use vmlinux.h of a specific kernel version as a "base" +version of header. To that extent, all vmlinux.h headers are versioned by +appending suffix to a file name. There is always a symbolic +link vmlinux.h, that points to whichever version is deemed to be default +(usually, latest). + +bpftool +------- + +bpftool is a universal tool used for inspection of BPF resources, as well as +providing various extra BPF-related facilities, like code-generation of BPF +program skeletons. The latter functionality is heavily used by these tools to +load and interact with BPF programs. + +Given bpftool package can't yet be expected to be available widely across many +distributions, bpftool binary is checked in into BCC repository in bin/ +subdirectory. Once bpftool package is more widely available, this can be +changed in favor of using pre-packaged version of bpftool. diff --git a/libbpf-tools/runqslower.bpf.c b/libbpf-tools/runqslower.bpf.c new file mode 100644 index 000000000..09abab252 --- /dev/null +++ b/libbpf-tools/runqslower.bpf.c @@ -0,0 +1,105 @@ +// SPDX-License-Identifier: GPL-2.0 +// Copyright (c) 2019 Facebook +#include "vmlinux.h" +#include +#include "runqslower.h" + +#define TASK_RUNNING 0 + +#define BPF_F_INDEX_MASK 0xffffffffULL +#define BPF_F_CURRENT_CPU BPF_F_INDEX_MASK + +const volatile __u64 min_us = 0;

The current documentation of the `-P` option indicates that it's used to "display stacks separately for each process", and this doesn't match with the intended usage. This patch has two parts: - Fix `tools/stackcount.py` to explicitly set perpid to True if `-p ` is used - Remove the `-P` option from the example of tracing single, isolated process in `tools/stackcount_example.txt`, since the usage of the option can be confusing (and unnecessary after the current change) --- tools/stackcount.py | 6 ++++++ tools/stackcount_example.txt | 2 +- 2 files changed, 7 insertions(+), 1 deletion(-) diff --git a/tools/stackcount.py b/tools/stackcount.py index a58f9e316..2afb91ff8 100755 --- a/tools/stackcount.py +++ b/tools/stackcount.py @@ -275,6 +275,12 @@ def __init__(self): self.kernel_stack = self.args.kernel_stacks_only self.user_stack = self.args.user_stacks_only + # For tracing single processes in isolation, explicitly set perpid + # to True, if not already set.

Adding the interface to define trampoline function for given kernel function via BPF_PROG macro, like: KFUNC_PROBE(do_sys_open, int dfd, const char *filename, int flags, int mode) { ... } which defines trampoline function with the 'kfunc__do_sys_open' name, that instruments do_sys_open kernel function before the function is executed. or: KRETFUNC_PROBE(do_sys_open, int dfd, const char *filename, int flags, int mode, int ret) { ... } which defines trampoline function with the 'kfunc__do_sys_open' name, that instruments do_sys_open kernel function after the function is executed. The main benefit is really lower overhead for trampolines (please see following commit for klockstat.py with perf comparison). Another benefit is the ability of kretfunc probe to access function arguments, so some tools might need only one program instead of entry/exit ones (please see following commit for opensnoop.py changes). Currently the interface does not allow to define function of different name than: kfunc__ or kretfunc__ which is sufficient by now, and can be easily changed in future if needed.

Even though do_sys_open still exists, it might be optimized off final binary depending on compilers. So we can't catch do_sys_open in some cases. This patch uses ksymname to try to get entries of open, openat and openat2, and changes the definitions of the trace functions to snoop them all. This works for both kprobe and kfunc.

We do not want to include libbpf/src/libbpf_internal.h as it is really libbpf internal. Let us define bcc version of btf_ext_header with struct name bcc_btf_ext_header.

In 5.9, tcp, udp and hash/array/sk_local_storage map iterators are implemented. This patch added necessary interface to support bpf_iter in bcc. A few C++ APIs are added to bcc. Two bpf_iter examples, task and sk_local_storage_map, are added to illustrate how bpf iterator can be implemented. Python interface can be added later if there is a need.

It's better than fiddling with the counts in userspace b/c if the userspace program crashes then the semaphore count does not get decremented. It's also better b/c the kernel can activate the semaphore for all processes that have the target mapped into memory. Currently with bcc, you have to provide the pid of each process you want to activate a semaphore for and then bcc will go poke /proc/pid/mem at the right offset. --- src/cc/api/BPF.cc | 6 ++++-- src/cc/api/BPF.h | 3 ++- src/cc/libbpf.c | 18 ++++++++++++------ src/cc/libbpf.h | 2 +- 4 files changed, 19 insertions(+), 10 deletions(-) diff --git a/src/cc/api/BPF.cc b/src/cc/api/BPF.cc index 1c1242c5b..b05caba36 100644 --- a/src/cc/api/BPF.cc +++ b/src/cc/api/BPF.cc @@ -225,7 +225,8 @@ StatusTuple BPF::attach_uprobe(const std::string& binary_path, const std::string& probe_func, uint64_t symbol_addr, bpf_probe_attach_type attach_type, pid_t pid, - uint64_t symbol_offset) { + uint64_t symbol_offset, + uint32_t ref_ctr_offset) { if (symbol_addr != 0 && symbol_offset != 0) return StatusTuple(-1, @@ -245,7 +246,8 @@ StatusTuple BPF::attach_uprobe(const std::string& binary_path, TRY2(load_func(probe_func, BPF_PROG_TYPE_KPROBE, probe_fd)); int res_fd = bpf_attach_uprobe(probe_fd, attach_type, probe_event.c_str(), - binary_path.c_str(), offset, pid); + binary_path.c_str(), offset, pid, + ref_ctr_offset); if (res_fd < 0) { TRY2(unload_func(probe_func)); diff --git a/src/cc/api/BPF.h b/src/cc/api/BPF.h index f3096d740..3038a112c 100644 --- a/src/cc/api/BPF.h +++ b/src/cc/api/BPF.h @@ -78,7 +78,8 @@ class BPF { uint64_t symbol_addr = 0, bpf_probe_attach_type attach_type = BPF_PROBE_ENTRY, pid_t pid = -1, - uint64_t symbol_offset = 0); + uint64_t symbol_offset = 0, + uint32_t ref_ctr_offset = 0); StatusTuple detach_uprobe(const std::string& binary_path, const std::string& symbol, uint64_t symbol_addr = 0, bpf_probe_attach_type attach_type = BPF_PROBE_ENTRY, diff --git a/src/cc/libbpf.c b/src/cc/libbpf.c index 329741e37..21efdf746 100644 --- a/src/cc/libbpf.c +++ b/src/cc/libbpf.c @@ -91,6 +91,8 @@ #define UNUSED(expr) do { (void)(expr); } while (0) +#define PERF_UPROBE_REF_CTR_OFFSET_SHIFT 32 + struct bpf_helper { char *name; char *required_version; @@ -838,7 +840,8 @@ static int bpf_get_retprobe_bit(const char *event_type) * the [k,u]probe.

It separates docker image builds into a separate github workflow, and refactors the package building process slightly, to be generic, in order to create builds for both ubuntu 16.04 and ubuntu 18.04. This provides a means to distribute intermediate apt packages between releases, and also enables uploading these as CI artifacts. As recent releases have not annotated their tags, it drops the requirement for tags to be annotated in selecting the version to use. --- .github/workflows/bcc-test.yml | 35 ------------ .github/workflows/publish.yml | 101 +++++++++++++++++++++++++++++++++ .gitignore | 4 ++ Dockerfile.ubuntu | 12 ++-- scripts/build-deb.sh | 2 +- scripts/docker/auth.sh | 19 +++++++ scripts/docker/build.sh | 27 +++++++++ scripts/docker/push.sh | 64 +++++++++++++++++++++ scripts/git-tag.sh | 2 +- 9 files changed, 225 insertions(+), 41 deletions(-) create mode 100644 .github/workflows/publish.yml create mode 100755 scripts/docker/auth.sh create mode 100755 scripts/docker/build.sh create mode 100755 scripts/docker/push.sh diff --git a/.github/workflows/bcc-test.yml b/.github/workflows/bcc-test.yml index 1a72ff541..4907e2941 100644 --- a/.github/workflows/bcc-test.yml +++ b/.github/workflows/bcc-test.yml @@ -92,38 +92,3 @@ jobs: #

I have verified this with disassembling vmlinux codes. https://www.systutorials.com/x86-64-calling-convention-by-gcc/ bcc previously used rcx for the 4th parameter for all cases. This patch fixed the issue by using r10 for syscalls. A macro PT_REGS_PARM4_SYSCALL() is also introduced in helpers.h to access the 4th parameter for r10.

Subject: [PATCH 0576/1261] libbpf-tools: add arm64 and powerpc vmlinux.h headers Add vmlinux.h for arm64 (aarch64) and powerpc (ppc64le) architectures. Makefile already normalizes aarch64 -> arm64 and ppc64le -> powerpc, so no adjustments are necessary.

For attachment to corresponding usdt uprobe, we can pass valid pid to perf_event_open() syscall so usdt is only triggered for this process, or pass pid -1 permits usdt is to triggered for all processes. There are use cases for usdt to be triggered for other processes than just one process. For example, for python usdt function__entry/function__return, users may want to trace usdt of a particular python process and all its children processes. C++ already has API to permit ignoring pid during attachment. attach_usdt(const USDT& usdt, pid_t pid = -1) This patch added similar functionality to python with an additional parameter to BPF constructor to indicate whether attach_usdt can ignore pid or not.

Details: The results, when built with gcc 9.3: nm ../linux.buildout/kernel/sched/core.o | grep finish_task_switch 0000000000001288 t finish_task_switch However, when built with gcc 10.2: nm ../linux.buildout/kernel/sched/core.o | grep finish_task_switch 00000000000012d0 t finish_task_switch.isra.0 The same symbols (with xxx.isra.0 or without, respectively of course) also appear in final file 'System.map' and in '/proc/kallsyms' when booting. This negatively impact the tracing tools commonly used in kernel debugging, such as bcc tools offcputime and runqlat. They hardcode 'finish_task_switch' (without the .isra.0 suffix) into their scripts. This patch fix the issue by changing the hardcoded 'finish_task_switch' string to a python regular expression pattern who can match both the traditional form 'finish_task_switch' and the new gcc10 form 'finish_task_switch.isra.0' (with single digit at the end). attach_kprobe()'s input parameter 'event_re' is used for this type of pattern matching.

Since an [upstream kernel patch](https://lore.kernel.org/linux-csky/20210226161151.2629097-1-arnd@kernel.org/) added these defines in a kernel header, we see the warning. This patch moves these definitions to a separate 'virtual' header that's included after virtual_bpf.h and adds an ifndef guard. As a result, newer kernels with the patch will not trigger the warning, while older kernels will not lose the definition. This should be safe based on my digging - some existing bcc programs use `__builtin_bswap` methods, but without checking HAVE_BUILTIN_BSWAP. Macros that may be conditionally defined based on HAVE_BUILTIN_BSWAP, like those in `bpf_endian.h`, aren't. If a similar macro or struct def in virtual_bpf.h - or any header it pulls in - changes depending on HAVE_BUILTIN_BSWAP this could cause problems on older kernels, but I don't believe that this is the case, or will be based on how infrequently the defines are checked. --- src/cc/export/bpf_workaround.h | 11 +++++++++++ src/cc/exported_files.cc | 4 ++++ src/cc/frontends/clang/kbuild_helper.cc | 3 --- 3 files changed, 15 insertions(+), 3 deletions(-) create mode 100644 src/cc/export/bpf_workaround.h diff --git a/src/cc/export/bpf_workaround.h b/src/cc/export/bpf_workaround.h new file mode 100644 index 000000000..732eab1fa --- /dev/null +++ b/src/cc/export/bpf_workaround.h @@ -0,0 +1,11 @@ +R"********( +#ifndef __HAVE_BUILTIN_BSWAP16__ +#define __HAVE_BUILTIN_BSWAP16__ +#endif +#ifndef __HAVE_BUILTIN_BSWAP32__ +#define __HAVE_BUILTIN_BSWAP32__ +#endif +#ifndef __HAVE_BUILTIN_BSWAP64__ +#define __HAVE_BUILTIN_BSWAP64__ +#endif +)********" diff --git a/src/cc/exported_files.cc b/src/cc/exported_files.cc index b9818e179..ec2c7d9f7 100644 --- a/src/cc/exported_files.cc +++ b/src/cc/exported_files.cc @@ -29,6 +29,10 @@ map<string, const char *> ExportedFiles::headers_ = { "/virtual/include/bcc/bpf.h", #include "compat/linux/virtual_bpf.h" }, + { + "/virtual/include/bcc/bpf_workaround.h", + #include "export/bpf_workaround.h" + }, { "/virtual/include/bcc/proto.h", #include "export/proto.h" diff --git a/src/cc/frontends/clang/kbuild_helper.cc b/src/cc/frontends/clang/kbuild_helper.cc index 5bed2721b..5c57c13ee 100644 --- a/src/cc/frontends/clang/kbuild_helper.cc +++ b/src/cc/frontends/clang/kbuild_helper.cc @@ -123,9 +123,6 @@ int KBuildHelper::get_flags(const char *uname_machine, vector<string> *cflags) { cflags->push_back("-include"); cflags->push_back("./include/linux/kconfig.h"); cflags->push_back("-D__KERNEL__"); - cflags->push_back("-D__HAVE_BUILTIN_BSWAP16__"); - cflags->push_back("-D__HAVE_BUILTIN_BSWAP32__"); - cflags->push_back("-D__HAVE_BUILTIN_BSWAP64__"); cflags->push_back("-DKBUILD_MODNAME=\"bcc\""); // If ARCH env variable is set, pass this along.

By using libdebuginfod we can query a server for a file containing debug information for a given ELF binary. The environment variable DEBUGINFOD_URLS has to be defined to an URL for a debuginfod server providing debug information files for your distribution or the federating server provided by the elfutils project: For example, to use the Fedora server, you would need: $ export DEBUGINFOD_URLS="https://debuginfod.fedoraproject.org/" Or for the elfutils server which federates to servers for openSUSE, Void Linux, Debian and Fedora, among others: $ export DEBUGINFOD_URLS="https://debuginfod.elfutils.org/" Calls to the debuginfod_find_debuginfo function from libdebuginfod will fail if the environment variable is not set, otherwise the library will attempt to download debug information for a build ID extracted from the binary in question and store it in a local cache directory.

Note that the buildbot only has Fedora 25-28 so it will not try to build libbcc with debuginfod support as the required packages are not available on these releases. For .deb packages there is no easy way to add dependencies dynamically, so we do not add dependencies to libdebuginfod there for now. For documentation purposes, however, let's add a comment indicating which changes are required for libdebuginfod support for downstream maintainers.

So we need two calls to fentry_exists to verify that whether a symbol exists. This commit updates this behavior to use the module name provided as a hint, and fallback to vmlinux if module BTF is not available.

Now we can replace ext4dist and treat it as an alias to fsdist. This commit removes ext4dist and replaces it with a symlink to fsdist.

That means that their attributes are bytes-typed, not string-typed. When a bytes-typed value is rendered into a string with Python's '%s' formatting directive, it gets a wrapped in single quotes and prefixed with b. For example, b'probe-location'. This is visually noisy, but also breaks some tool behavior which uses string-formatted values for stuff like filters. This is only an issue in Python 3. In Python 2, the bytes type is just an alias for the string type, and so byte sequences from libcc were implicitly decoded as ASCII text. --- src/python/bcc/usdt.py | 16 ++++++++-------- tools/tplist.py | 4 ++-- 2 files changed, 10 insertions(+), 10 deletions(-) diff --git a/src/python/bcc/usdt.py b/src/python/bcc/usdt.py index 87f68d111..b96ac0eb4 100644 --- a/src/python/bcc/usdt.py +++ b/src/python/bcc/usdt.py @@ -50,24 +50,24 @@ def _format(self): if self.valid & BCC_USDT_ARGUMENT_FLAGS.CONSTANT != 0: return "%d" % self.constant if self.valid & BCC_USDT_ARGUMENT_FLAGS.DEREF_OFFSET == 0: - return "%s" % self.base_register_name + return "%s" % self.base_register_name.decode() if self.valid & BCC_USDT_ARGUMENT_FLAGS.DEREF_OFFSET != 0 and \ self.valid & BCC_USDT_ARGUMENT_FLAGS.DEREF_IDENT == 0: if self.valid & BCC_USDT_ARGUMENT_FLAGS.INDEX_REGISTER_NAME != 0: - index_offset = " + %s" % self.index_register_name + index_offset = " + %s" % self.index_register_name.decode() if self.valid & BCC_USDT_ARGUMENT_FLAGS.SCALE != 0: index_offset += " * %d" % self.scale else: index_offset = "" sign = '+' if self.deref_offset >= 0 else '-' - return "*(%s %s %d%s)" % (self.base_register_name, - sign, abs(self.deref_offset), index_offset) + return "*(%s %s %d%s)" % (self.base_register_name.decode(), + sign, abs(self.deref_offset), index_offset) if self.valid & BCC_USDT_ARGUMENT_FLAGS.DEREF_OFFSET != 0 and \ self.valid & BCC_USDT_ARGUMENT_FLAGS.DEREF_IDENT != 0 and \ self.valid & BCC_USDT_ARGUMENT_FLAGS.BASE_REGISTER_NAME != 0 and \ self.base_register_name == "ip": sign = '+' if self.deref_offset >= 0 else '-' - return "*(&%s %s %d)" % (self.deref_ident, + return "*(&%s %s %d)" % (self.deref_ident.decode(), sign, abs(self.deref_offset)) # If we got here, this is an unrecognized case.

Unfortunately this caused a redefinition of BPF.XDP, which was similarly pulled in from `bpf_prog_type` enum, thus breaking program loading (#3489). Let's pull these enum- and flag-type class variables out into their own wrapper classes. For backwards compatibility, keep them all (except for `bpf_attach_type`, which was merged 2 days ago) defined in the BPF class, but add a comment to not continue doing this. --- docs/reference_guide.md | 8 ++-- examples/networking/sockmap.py | 10 ++--- src/python/bcc/__init__.py | 73 +++++++++++++++++++++++++++------- 3 files changed, 67 insertions(+), 24 deletions(-) diff --git a/docs/reference_guide.md b/docs/reference_guide.md index 92be49e9b..aa7db55e3 100644 --- a/docs/reference_guide.md +++ b/docs/reference_guide.md @@ -1858,8 +1858,8 @@ Attaches a BPF function of the specified type to a particular ```attachable_fd`` For example: ```Python -b.attach_func(fn, cgroup_fd, b.CGROUP_SOCK_OPS) -b.attach_func(fn, map_fd, b.SK_MSG_VERDICT) +b.attach_func(fn, cgroup_fd, BPFAttachType.CGROUP_SOCK_OPS) +b.attach_func(fn, map_fd, BPFAttachType.SK_MSG_VERDICT) ``` Note.

A few potential solutions were discussed in that issue, we settled on treating the main exe like any other map in `/proc/PID/maps`.

"Runtime" in this context means everything except the stuff that depends on clang/LLVM. libbcc_bpf.so was originally created in fa073456 ("make libbpf standalone-ready") with (I'm guessing) the intent of creating bcc-libbpf. That has been superceded by libbpf (separate repo) so I don't think it should be used much anymore. This updated libbcc_bpf.so will be used by ahead-of-time compiled bpftrace scripts[0] to drop the dependency on LLVM/clang for the runtime component.

Thus +we turn to use a PERCPU_ARRAY to record the 'cache hit' situation to speed +things up; and for other cases, then use a percpu_hash. + +As RAW_TRACEPOINT_PROBE(kvm_exit) consumes less cpu cycles, when this tool is +used, it firstly tries to employ raw tracepoints in modules, and if failes, +then fall back to regular tracepoint. + +Limitation: In view of the hardware-assisted virtualization technology of +different architectures, currently we only adapt on vmx in intel. + +Since this uses BPF, only the root user can use this tool. +.SH REQUIREMENTS +CONFIG_BPF and bcc. + +This also requires Linux 4.7+ (BPF_PROG_TYPE_TRACEPOINT support). +.SH OPTIONS +.TP +\-h +Print usage message. +.TP +\-p PID +Display process with this PID only, collpase all tids with exit reasons sorted +in descending order. +.TP +\-v VCPU +Display this VCPU only for this PID. +.TP +\-a ALLTIDS +Display all TIDS for this PID. +.TP +\-t TID +Display thread with this TID only with exit reasons sorted in descending order. +.TP +\-T 'TID1,TID2' +Display threads for a union like {395490, 395491}. +.TP +duration +Duration of display, after sleeping several seconds. +.SH EXAMPLES +.TP +Display kvm exit reasons and statistics for all threads...

A thread write to multi files with the same name would add up to same value in the map which can be repro by the following command: $ cat somefile | tee /foo/bar/xxx /fuz/baz/xxx Let us add device number and inode number to uniquely identify a file.

The bpf_attach_perf_event_raw API provide flexibility to use advanced features of perf events with BPF. Presently, this API is available to use in BPF programs via C and C++ interface. Patch enables support to use in python interface. Patch also adds testcase under 'tests/python' which uses the newly added python interface 'attach_perf_event_raw'.

Specifically: * All named fields are added, including field names within anonymous unions and bitfields * Perf.perf_event_attr now complains when a field which isn't part of the ctype struct is set. * Goal here is to prevent users from setting a recently-added field - which we haven't updated the ctype _fields_ to include - and getting confused when it doesn't propagate to the perf_event_open syscall. This bit me in #3571 and I am pretty familiar with bcc internals so I'd like to prevent this from confusing others down the line. * Perf.perf_event_attr's 'flags' field is removed as it was a standin for the bitfields. The _old_ profile.py was the only script in bcc tools that I could find using this. The last bullet is a breaking change. Although `tools/old/profile.py` has been migrated to use the bitfield it was flipping using `flags`, there could be some scripts out in the wild which break. I don't think this is likely: this stuff hasn't been significantly touched since 2016 and I suspect if users of the python interface were writing lots of perf_event programs we would've seen more python tools or activity here. Regardless, there is probably a way to keep `flags` field working while also exposing named bitfields, but I suspect it'll be ugly and wanted to see if anyone thought it was necessary. --- src/python/bcc/perf.py | 119 ++++++++++++++++++++++++++++++++++------- 1 file changed, 99 insertions(+), 20 deletions(-) diff --git a/src/python/bcc/perf.py b/src/python/bcc/perf.py index b1c13f72d..513274375 100644 --- a/src/python/bcc/perf.py +++ b/src/python/bcc/perf.py @@ -16,32 +16,114 @@ import os from .utils import get_online_cpus +class _sample_period_union(ct.Union): + _fields_ = [ + ('sample_period', ct.c_ulong), + ('sample_freq', ct.c_ulong), + ] + +class _wakeup_events_union(ct.Union): + _fields_ = [ + ('wakeup_events', ct.c_uint), + ('wakeup_watermark', ct.c_uint), + ] + +class _bp_addr_union(ct.Union): + _fields_ = [ + ('bp_addr', ct.c_ulong), + ('kprobe_func', ct.c_ulong), + ('uprobe_path', ct.c_ulong), + ('config1', ct.c_ulong), + ] + +class _bp_len_union(ct.Union): + _fields_ = [ + ('bp_len', ct.c_ulong), + ('kprobe_addr', ct.c_ulong), + ('probe_offset', ct.c_ulong), + ('config2', ct.c_ulong), + ] + class Perf(object): + class perf_event_attr(ct.Structure): + _anonymous_ = [ + "_sample_period_union", + "_wakeup_events_union", + "_bp_addr_union", + "_bp_len_union" + ] + _fields_ = [ ('type', ct.c_uint), ('size', ct.c_uint), ('config', ct.c_ulong), -

Shorten the sleep duration so test finishes faster - since it's just testing attach currently the extra time isn't producing more signal. Also add python equivalent of `perf_event_sample_format` enum so `sample_type` can be more clearly set. v2: The test doesn't work on ubuntu 16.04 due to old kernel headers. It doesn't work on the rest of the github actions VMs due to hardware perf events not being supported, so add necessary check / skip. --- src/python/bcc/__init__.py | 28 ++++++++++++++++++++++++++ tests/python/CMakeLists.txt | 2 ++ tests/python/test_attach_perf_event.py | 11 ++++++---- 3 files changed, 37 insertions(+), 4 deletions(-) diff --git a/src/python/bcc/__init__.py b/src/python/bcc/__init__.py index 76678e6ef..c8986388e 100644 --- a/src/python/bcc/__init__.py +++ b/src/python/bcc/__init__.py @@ -141,6 +141,34 @@ class PerfSWConfig: DUMMY = 9 BPF_OUTPUT = 10 +class PerfEventSampleFormat: + # from perf_event_sample_format in uapi/linux/bpf.h + IP = (1 << 0) + TID = (1 << 1) + TIME = (1 << 2) + ADDR = (1 << 3) + READ = (1 << 4) + CALLCHAIN = (1 << 5) + ID = (1 << 6) + CPU = (1 << 7) + PERIOD = (1 << 8) + STREAM_ID = (1 << 9) + RAW = (1 << 10) + BRANCH_STACK = (1 << 11) + REGS_USER = (1 << 12) + STACK_USER = (1 << 13) + WEIGHT = (1 << 14) + DATA_SRC = (1 << 15) + IDENTIFIER = (1 << 16) + TRANSACTION = (1 << 17) + REGS_INTR = (1 << 18) + PHYS_ADDR = (1 << 19) + AUX = (1 << 20) + CGROUP = (1 << 21) + DATA_PAGE_SIZE = (1 << 22) + CODE_PAGE_SIZE = (1 << 23) + WEIGHT_STRUCT = (1 << 24) + class BPFProgType: # From bpf_prog_type in uapi/linux/bpf.h SOCKET_FILTER = 1 diff --git a/tests/python/CMakeLists.txt b/tests/python/CMakeLists.txt index 3cd96031c..d86fcab6b 100644 --- a/tests/python/CMakeLists.txt +++ b/tests/python/CMakeLists.txt @@ -63,6 +63,8 @@ add_test(NAME py_test_tracepoint WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} COMMAND ${TEST_WRAPPER} py_test_tracepoint sudo ${CMAKE_CURRENT_SOURCE_DIR}/test_tracepoint.py) add_test(NAME py_test_perf_event WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} COMMAND ${TEST_WRAPPER} py_test_perf_event sudo ${CMAKE_CURRENT_SOURCE_DIR}/test_perf_event.py) +add_test(NAME py_test_attach_perf_event WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} + COMMAND ${TEST_WRAPPER} py_test_attach_perf_event sudo ${CMAKE_CURRENT_SOURCE_DIR}/test_attach_perf_event.py) add_test(NAME py_test_utils WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} COMMAND ${TEST_WRAPPER} py_test_utils sudo ${CMAKE_CURRENT_SOURCE_DIR}/test_utils.py) add_test(NAME py_test_percpu WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} diff --git a/tests/python/test_attach_perf_event.py b/tests/python/test_attach_perf_event.py index c53f450e0..d0cea065f 100755 --- a/tests/python/test_attach_perf_event.py +++ b/tests/python/test_attach_perf_event.py @@ -6,11 +6,14 @@ import os import time import unittest -from bcc import BPF, PerfType, PerfHWConfig +from bcc import BPF, PerfType, PerfHWConfig, PerfEventSampleFormat from bcc import Perf from time import sleep +from utils import kernel_version_ge, mayFail class TestPerfAttachRaw(unittest.TestCase): + @mayFail("This fails on github actions environment, hw perf events are not supported") + @unittest.skipUnless(kernel_version_ge(4,9), "requires kernel >= 4.9") def test_attach_raw_event(self): bpf_text=""" #include <linux/perf_event.h> @@ -50,15 +53,15 @@ def test_attach_raw_event(self): event_attr.type = Perf.PERF_TYPE_HARDWARE event_attr.config = PerfHWConfig.CACHE_MISSES event_attr.sample_period = 1000000 - event_attr.sample_type = 0x8 # PERF_SAMPLE_ADDR + event_attr.sample_type = PerfEventSampleFormat.ADDR event_attr.exclude_kernel = 1 b.attach_perf_event_raw(attr=event_attr, fn_name="on_sample_hit", pid=-1, cpu=-1) except Exception: print("Failed to attach to a raw event.

This patch uses a <ev_name, <fn_name, fd>> map to build the corresponding relationship among the kprobe event, handler function names, and fds. Then we can detach any single handler function, which is pretty helpful if the developer wants to enable and disable kprobes/kretprobes dynamically. For example: We want to measure both the execution count, execution time, and some other metrics of a kernel function. For flexibility, we want to use separate handlers for each metric to disable them individually if any of them incur some performance penalties. Without this interface, we have to disable all handlers on the kernel function. The uprobe also has a similar problem. I will fix it in a subsequent patch.

For example, to create a string representation of a "struct sk_buff", the pointer to the skb data is provided along with the type id of "struct sk_buff". Here that functionality is utilized to support tracing kernel function entry and return using k[ret]probes. The "struct pt_regs" context can be used to derive arguments and return values, and when the user supplies a function name we - look it up in /proc/kallsyms to find its address/module - look it up in the BTF kernel/module data to get types of arguments and return value - store a map representation of the trace information, keyed by function address On function entry/return we look up info about the arguments (is it a pointer? what size of data do we copy?) and call bpf_probe_read() to copy the data into our trace buffers. These are then sent via perf event to userspace, and since we know the associated BTF id, we can dump the typed data using btf_dump__dump_type_data(). ksnoop can be used to show function signatures; for example: $ ksnoop info ip_send_skb int ip_send_skb(struct net * net, struct sk_buff * skb); Then we can trace the function, for example: $ ksnoop trace ip_send_skb TIME CPU PID FUNCTION/ARGS 78101668506811 1 2813 ip_send_skb( net = *(0xffffffffb5959840) (struct net){ .passive = (refcount_t){ .refs = (atomic_t){ .counter = (int)0x2, }, }, .dev_base_seq = (unsigned int)0x18, .ifindex = (int)0xf, .list = (struct list_head){ .next = (struct list_head *)0xffff9895 .prev = (struct list_head *)0xffffffff }, [output truncated] 78178228354796 1 2813 ip_send_skb( return = (int)0x0 ); We see the raw value of pointers along with the typed representation of the data they point to. Up to five arguments are supported. The arguments are referred to via name (e.g. skb, net), and the return value is referred to as "return" (using the keyword ensures we can never clash with an argument name). ksnoop can select specific arguments/return value rather than tracing everything; for example: $ ksnoop "ip_send_skb(skb)" ...will only trace the skb argument. A single level of reference is supported also, for example: $ ksnoop "ip_send_skb(skb->sk)" or Simple predicates (==, !=, <, <=, >, >=) can also be specified; for example, to show skbs where the length is > 255: $ ksnoop "ip_rcv(skb->len > 0xff,skb)" TIME CPU PID FUNCTION/ARGS 32461869484376 1 2955 ip_rcv( skb->len = (unsigned int)0x127, skb = *(0xffff89c99623a000) (struct sk_buff){ (union){ .sk = (struct sock *)0xffff89c880b37000, .ip_defrag_offset = (int)0x80b37000, }, We can also specify a combination of entry/return predicates; when such a combination is specified, data on entry (assuming it matches the predicate) is "stashed" for retrieval on return. This allows us to ask questions like "show entry arguments for function foo when it returned a non-zero value indicating error"; $ ksnoop "sock_sendmsg(skb, return != 0)" Multiple functions can be specified also. In addition, using "stack" (-s) mode, it is possible to specify that a sequence of functions should be traced, but only if function A calls function B (either directly or indirectly). For example, in specifying $ ksnoop -s tcp_sendmsg __tcp_transmit_skb ip_output ...we are saying we are only interested in tcp_sendmsg() function calls that in turn issue calls to __tcp_transmit_skb(), and these in turn eventually call ip_output(), and that we only want to see their entry and return. This mode is useful for investigating behaviour with a specific stack signature, allowing us to see function/argument information for specific call chains only. Finally, module support is included too, provided module BTF is present in /sys/kernel/btf : $ ksnoop iwl_trans_send_cmd TIME CPU PID FUNCTION/ARGS 80046971419383 3 1038 iwl_trans_send_cmd( trans = *(0xffff989564d20028) (struct iwl_trans){ .ops = (struct iwl_trans_ops *)0xffffff .op_mode = (struct iwl_op_mode *)0xffff .trans_cfg = (struct iwl_cfg_trans_para The goal pursued here is not to add another tracer to the world - there are plenty of those - but rather to demonstrate feature usage for deep data display in the hope that other tracing technologies make use of this functionality. In the meantime, having a simple tracer like this plugs the gap and can be quite helpful for kernel debugging.

Before this commit, that line was written in C natural syntax and we're relying on the BCC rewriter to transform that to valid eBPF code by emitting some bpf_probe_read calls. This support was not working when using opensnoop in systems supporting kfuncs because in this case the BCC rewriter doesn't transform that line and the verifier claims about an invalid memory access: 7: (85) call bpf_get_current_task#35; return current_task->nsproxy->mnt_ns->ns.inum; 8: (79) r1 = *(u64 *)(r0 +2896) R0 invalid mem access 'inv' This commit fixes that by explicitly using bpf_probe_kernel_read() instead of the C natural syntax.

Most of the tools that use perf_buffer__poll() were not handling the case when it was interrupted by a signal, they were just ending. We noticed this issue by running the tools inside a container, after some seconds they will finish: ``` $ time /execsnoop ... runc 210198 939 0 /usr/sbin/runc --version docker-init 210205 939 0 /usr/bin/docker-init --version Error polling perf buffer: -4 real 0m48.913s user 0m0.020s sys 0m0.033s ``` This commit fixes that by checking if errno is EINTR after calling perf_buffer__poll(). 2. Many tools were returning non zero when ended by SIG_INT. ``` $ sudo ./execsnoop PCOMM PID PPID RET ARGS runc 203967 939 0 /usr/sbin/runc --version docker-init 203973 939 0 /usr/bin/docker-init --version calico 203974 724 0 /opt/cni/bin/calico portmap 203985 724 0 /opt/cni/bin/portmap bandwidth 203990 724 0 /opt/cni/bin/bandwidth ^C $ echo $? 130 ``` 3.

The off=2048 value is a clue; this suggests an index resulting from an underflow of the __u8 index value. Adding a bitmask to the decrement operation solves the problem. It appears that the guards on stack_depth size around the array dereference were optimized out.

It works fine if irq is triggered while normal task running, but there is a chance causing overwrite issue while irq is triggered while idle task (a.k.a swapper/x, tid=0) running on multi-core system. Let's say there are two irq event trigger simultaneously on both CPU core, irq A @ core #0, irq B @ core #1, and system load is pretty light, so BPF program will get tid=0 since current task is swapper/x for both cpu core. In this case, the information of first irq event stored in map could be overwritten by incoming second irq event.

Currently, when a tool exits in an unexpected way (e.g. we expected a HUP to be required, but the tool required a KILL), the test failure message isn't very descriptive.

The -translation is performed by generating programs written in a subset of -the C programming language, that are converted to EBPF using the BPF -Compiler Collection tools. - -The compiler code is licensed under an [Apache v2.0 license] -(http://www.apache.org/licenses/LICENSE-2.0.html). - -## Preliminaries - -In this section we give a brief overview of P4 and EBPF. A detailed -treatment of these topics is outside the scope of this text. - -### P4 - -P4 (http://p4.org) is a domain-specific programming language for -specifying the behavior of the dataplanes of network-forwarding -elements. The name of the programming language comes from the title -of a paper published in the proceedings of SIGCOMM Computer -Communications Review in 2014: -http://www.sigcomm.org/ccr/papers/2014/July/0000000.0000004: -"Programming Protocol-Independent Packet Processors". - -P4 itself is protocol-independent but allows programmers to express a -rich set of data plane behaviors and protocols. The core P4 -abstractions are: - -* Header definitions describe the format (the set of fields and their - sizes) of each header within a packet. - -* Parse graphs (finite-state machines) describe the permitted header - sequences within received packets. - -* Tables associate keys to actions. P4 tables generalize traditional - forwarding tables; they can be used to implement routing tables, - flow lookup tables, access-control lists, etc. - -* Actions describe how packet header fields and metadata are manipulated. - -* Match-action units stitch together tables and actions, and perform - the following sequence of operations: - - * Construct lookup keys from packet fields or computed metadata, - - * Use the constructed lookup key to index into tables, choosing an - action to execute, - - * Finally, execute the selected action. - -* Control flow is expressed as an imperative program describing the - data-dependent packet processing within a pipeline, including the - data-dependent sequence of match-action unit invocations. - -P4 programs describe the behavior of network-processing dataplanes. A -P4 program is designed to operate in concert with a separate *control -plane* program. The control plane is responsible for managing at -runtime the contents of the P4 tables. P4 cannot be used to specify -control-planes; however, a P4 program implicitly specifies the -interface between the data-plane and the control-plane. - -The P4 language is under active development; the current stable -version is 1.0.2 (see http://p4.org/spec); a reference implementation -of a compiler and associated tools is freely available using a Apache -2 open-source license (see http://p4.org/code). - -### EBPF - -#### Safe code - -EBPF is a acronym that stands for Extended Berkeley Packet Filters. -In essence EBPF is a low-level programming language (similar to -machine code); EBPF programs are traditionally executed by a virtual -machine that resides in the Linux kernel. EBPF programs can be -inserted and removed from a live kernel using dynamic code -instrumentation. The main feature of EBPF programs is their *static -safety*: prior to execution all EBPF programs have to be validated as -being safe, and unsafe programs cannot be executed. A safe program -provably cannot compromise the machine it is running on: - -* it can only access a restricted memory region (on the local stack) - -* it can run only for a limited amount of time; during execution it - cannot block, sleep or take any locks - -* it cannot use any kernel resources with the exception of a limited - set of kernel services which have been specifically whitelisted, - including operations to manipulate tables (described below) - -#### Kernel hooks - -EBPF programs are inserted into the kernel using *hooks*. There are -several types of hooks available: - -* any function entry point in the kernel can act as a hook; attaching - an EBPF program to a function `foo()` will cause the EBPF program to - execute every time some kernel thread executes `foo()`. - -* EBPF programs can also be attached using the Linux Traffic Control - (TC) subsystem, in the network packet processing datapath. Such - programs can be used as TC classifiers and actions. - -* EBPF programs can also be attached to sockets or network interfaces. - In this case they can be used for processing packets that flow - through the socket/interface. - -EBPF programs can be used for many purposes; the main use cases are -dynamic tracing and monitoring, and packet processing. We are mostly -interested in the latter use case in this document. - -#### EBPF Tables - -The EBPF runtime exposes a bi-directional kernel-userspace data -communication channel, called *tables* (also called maps in some EBPF -documents and code samples). EBPF tables are essentially key-value -stores, where keys and values are arbitrary fixed-size bitstrings. -The key width, value width and table size (maximum number of entries -that can be stored) are declared statically, at table creation time. - -In user-space tables handles are exposed as file descriptors. Both -user- and kernel-space programs can manipulate tables, by inserting, -deleting, looking up, modifying, and enumerating entries in a table. - -In kernel space the keys and values are exposed as pointers to the raw -underlying data stored in the table, whereas in user-space the -pointers point to copies of the data. - -#### Concurrency - -An important aspect to understand related to EBPF is the execution -model. An EBPF program is triggered by a kernel hook; multiple -instances of the same kernel hook can be running simultaneously on -different cores. - -Each table however has a single instances across all the cores. A -single table may be accessed simultaneously by multiple instances of -the same EBPF program running as separate kernel threads on different -cores. EBPF tables are native kernel objects, and access to the table -contents is protected using the kernel RCU mechanism. This makes -access to table entries safe under concurrent execution; for example, -the memory associated to a value cannot be accidentally freed while an -EBPF program holds a pointer to the respective value. However, -accessing tables is prone to data races; since EBPF programs cannot -use locks, some of these races often cannot be avoided. - -EBPF and the associated tools are also under active development, and -new capabilities are added frequently. The P4 compiler generates code -that can be compiled using the BPF Compiler Collection (BCC) -(https://github.com/iovisor/bcc) - -## Compiling P4 to EBPF - -From the above description it is apparent that the P4 and EBPF -programming languages have different expressive powers. However, -there is a significant overlap in their capabilities, in particular, -in the domain of network packet processing. The following image -illustrates the situation: - -![P4 and EBPF overlap in capabilities](scope.png) - -We expect that the overlapping region will grow in size as both P4 and -EBPF continue to mature. - -The current version of the P4 to EBPF compiler translates programs -written in the version 1.1 of the P4 programming language to programs -written in a restricted subset of C. The subset of C is chosen such -that it should be compilable to EBPF using BCC. - -``` - -------------- ------- -P4 ---> | P4-to-EBPF | ---> C ----> | BCC | --> EBPF - -------------- ------- -``` - -The P4 program only describes the packet processing *data plane*, that -runs in the Linux kernel. The *control plane* must be separately -implemented by the user. The BCC tools simplify this task -considerably, by generating C and/or Python APIs that expose the -dataplane/control-plane APIs. - -### Dependencies - -EBPF programs require a Linux kernel with version 4.2 or newer. - -In order to use the P4 to EBPF compiler the following software must be installed: - -* The compiler itself is written in the Python (v2.x) programming - language. - -* the P4 compiler front-end: (https://github.com/p4lang/p4-hlir). - This is required for parsing the P4 programs. - -* the BCC compiler collection tools: (https://github.com/iovisor/bcc). - This is required for compiling the generated code. Also, BCC comes - with a set of Python utilities which can be used to implement - control-plane programs that operate in concert with the kernel EBPF - datapath. - -The P4 to EBPF compiler generates code that is designed for being used -as a classifier using the Linux TC subsystem. - -Furthermore, the test code provided is written using the Python (v3.x) -programming language and requires several Python packages to be -installed. - -### Supported capabilities - -The current version of the P4 to EBPF compiler supports a relatively -narrow subset of the P4 language, but still powerful enough to write -very complex packet filters and simple packet forwarding engines. In -the spirit of open-source "release early, release often", we expect -that the compiler's capabilities will improve gradually. - -* Packet filtering is performed using the `drop()` action. Packets - that are not dropped will be forwarded. - -* Packet forwarding is performed by setting the - `standard_metadata.egress_port` to the index of the destination - network interface - -Here are some limitations imposed on the P4 programs: - -* Currently both the ingress and the egress P4 pipelines are executed - at the same hook (wherever the user chooses to insert the generated - EBPF program). In the future the compiler should probably generate - two separate EBPF programs. - -* arbitrary parsers can be compiled, but the BCC compiler will reject - parsers that contain cycles - -* arithmetic on data wider than 32 bits is not supported - -* checksum computations are not implemented. In consequence, programs - that IP/TCP/UDP headers will produce incorrect packet headers. - -* EBPF does not offer support for ternary or LPM tables - -* P4 cloning and recirculation and not supported - -* meters and registers are not supported; only direct counters are - currently supported. EBPF can potentially support registers and - arbitrary counters, so these may appear in the future. - -* learning (i.e. `generate_digest`) is not implemented - -### Translating P4 to C - -To simplify the translation, the P4 programmer should refrain using -identifiers whose name starts with `ebpf_`. - -The following table provides a brief summary of how each P4 construct -is mapped to a corresponding C construct: - -#### Translating parsers - -P4 Construct | C Translation -----------|------------ -`header_type` | `struct` type -`header` | `struct` instance with an additional `valid` bit -`metadata` | `struct` instance -parser state | code block -state transition | `goto` statement -`extract` | load/shift/mask data from packet buffer - -#### Translating match-action pipelines - -P4 Construct | C Translation -----------|------------ -table | 2 EBPF tables: second one used just for the default action -table key | `struct` type -table `actions` block | tagged `union` with all possible actions -`action` arguments | `struct` -table `reads` | EBPF table access -`action` body | code block -table `apply` | `switch` statement -counters | additional EBPF table - -### Code organization - -The compiler code is organized in two folders: - -* `compiler`: the complete compiler source code, in Python v2.x - The compiler entry point is `p4toEbpf.py`. - -* `test`: testing code and data. There are two testing programs: - * `testP4toEbpf.py`: which compiles all P4 files in the testprograms folder - - * `endToEndTest.py`: which compiles and executes the simple.p4 - program, and includes a simple control plane - -Currently the compiler contains no installation capabilities. - -### Invoking the compiler - -Invoking the compiler is just a matter of invoking the python program -with a suitable input P4 file: - -``` -p4toEbpf.py file.p4 -o file.c -``` - -#### Compiler options - -The P4 compiler first runs the C preprocessor on the input P4 file. -Some of the command-line options are passed directly to the -preprocessor. - -The following compiler options are available: - -Option | Meaning --------|-------- -`-D macro` | Option passed to C preprocessor -`-I path` | Option passed to C preprocessor -`-U macro` | Option passed to C preprocessor -`-g [router|filter]` | Controls whether the generated code behaves like a router or a filter. -`-o outoutFile` | writes the generated C code to the specified output file. - -The `-g` option controls the nature of the generated code: - -* `-g filter` generates a filter; the only P4 action that has an - effect is the `drop()` action. Setting metadata in P4 (e.g., - `egress_port`) has no effect. - -* `-g router` generates a simple router; both `drop()` and - `egress_port` impact packet processing. - -#### Using the generated code - -The resulting file contains the complete data structures, tables, and -a C function named `ebpf_filter` that implements the P4-specified -data-plane. This C file can be manipulated using the BCC tools; -please refer to the BCC project documentation and sample test files of -the P4 to EBPF source code for an in-depth understanding. A minimal -Python program that compiles and loads into the kernel the generated -file into EBPF is: - -``` -#!/usr/bin/env python3 -from bcc import BPF - -b = BPF(src_file="file.c", debug=0) -fn = b.load_func("ebpf_filter", BPF.SCHED_CLS) -``` - -##### Connecting the generated program with the TC - -The EBPF code that is generated is intended to be used as a classifier -attached to the ingress packet path using the Linux TC subsystem. The -same EBPF code should be attached to all interfaces. Note however -that all EBPF code instances share a single set of tables, which are -used to control the program behavior. - -The following code fragment illustrates how the EBPF code can be -hooked up to the `eth0` interface using a Python program. (The `fn` -variable is the one produced by the previous code fragment). - -``` -from pyroute2 import IPRoute - -ipr = IPRoute() -interface_name="eth0" -if_index = ipr.link_lookup(ifname=interface_name)[0] -ipr.tc("add", "ingress", if_index, "ffff:") -ipr.tc("add-filter", "bpf", if_index, ":1", fd=fn.fd, -

I expected that this would result in the tests running on both 18.04 and 20.04. Unfortunately this change was effectively a no-op as the tests are run in a Docker container and the os field in bcc-test.yml dictates the type/version of the _host_ OS, not the container's OS. So it's not necessary to run on both, just run on 20.04. It will be necessary to modify Dockerfile.test to use both 18.04 and 20.04. To prepare for this, move all python tests to use python3 interpreter, as 20.04 doesn't have python2 pip readily available. Also, refactor Dockerfile.tests a bit so that it's possible to provide ubuntu version and shortname as build input. This commit does not result in the docker test container working/running both 18.04 and 20.04, rather lays groundwork for future commits to do so.

Bumping to 11 causes test_disassembler to fail because it expects a map w/ a certain format with FD 3, and the LLVM bump causes the map to be FD 4. The purpose of the test is to ensure that the format of the diassembled map is correct, not that it has a specific FD, so make some small changes to the test so that it doesn't care what the FD number is. --- Dockerfile.tests | 2 +- tests/python/test_disassembler.py | 20 +++++++++++++++++++- 2 files changed, 20 insertions(+), 2 deletions(-) diff --git a/Dockerfile.tests b/Dockerfile.tests index 3b082364b..c43b22cf3 100644 --- a/Dockerfile.tests +++ b/Dockerfile.tests @@ -1,7 +1,7 @@ ARG UBUNTU_VERSION="18.04" FROM ubuntu:${UBUNTU_VERSION} -ARG LLVM_VERSION="8" +ARG LLVM_VERSION="11" ENV LLVM_VERSION=$LLVM_VERSION ARG UBUNTU_SHORTNAME="bionic" diff --git a/tests/python/test_disassembler.py b/tests/python/test_disassembler.py index bf324d2b3..794309a95 100755 --- a/tests/python/test_disassembler.py +++ b/tests/python/test_disassembler.py @@ -151,7 +151,25 @@ def test_func(self): 1: (95) exit""", b.disassemble_func("test_func")) - self.assertEqual( + def _assert_equal_ignore_fd_id(s1, s2): + # In first line of string like + # Layout of BPF map test_map (type HASH, FD 3, ID 0): + # Ignore everything from FD to end-of-line + # Compare rest of string normally + s1_lines = s1.split('\n') + s2_lines = s2.split('\n') + s1_first_cut = s1_lines[0] + s1_first_cut = s1_first_cut[0:s1_first_cut.index("FD")] + s2_first_cut = s2_lines[0] + s2_first_cut = s2_first_cut[0:s2_first_cut.index("FD")] + + self.assertEqual(s1_first_cut, s2_first_cut) + + s1_rest = '\n'.join(s1_lines[1:]) + s2_rest = '\n'.join(s2_lines[1:]) + self.assertEqual(s1_rest, s2_rest) + + _assert_equal_ignore_fd_id( """Layout of BPF map test_map (type HASH, FD 3, ID 0): struct { int a; From 9a45c3c9e162e1e8e4eb3f267bdc2084c42b328b Mon Sep 17 00:00:00 2001 From: Dave Marchevsky <davemarchevsky@fb.com> Date: Mon, 20 Dec 2021 23:05:16 -0500 Subject: [PATCH 0892/1261] docker: Run tests on ubuntu-20.04 as well Move bcc-test github action's `matrix.os` to indicate the OS to run in the container, not the test runner itself (just pin the latter to ubuntu-20.04).

Like sk local storage, this commit allows creating inode/task local storage using BPF_{INODE, TASK}_STORAGE macros, and manipulating maps using map.{inode, task}_storage_get() and map.{inode, task}_storage_delete() helpers.

This commit introduces such an API, perf_reader_consume, modeled after libbpf's perf_buffer__consume. Future work will refactor bcc to use libbpf's perf buffer support as much as possible instead of duplicating functionality.

This is the code that generates custom sscanf and printf functions for BPF map defs. These generated functions are used to serialize arguments to update_value (and similar calls which take string as input) to the correct key / value types. It's still possible to use update_value and its ilk without rw_engine enabled, just need to use the variants that take raw bytes and do serialization manually. In the future we can add some simple sscanf/printfs for common types that can be used without LLVM generation. For now, when rw_engine is disabled, it's fine to skip tests that require these autogenerated functions. --- src/cc/bcc_common.cc | 4 ++++ src/cc/bcc_common.h | 1 + src/python/bcc/libbcc.py | 2 ++ tests/cc/test_bpf_table.cc | 4 ++-- tests/python/test_clang.py | 4 ++++ 5 files changed, 13 insertions(+), 2 deletions(-) diff --git a/src/cc/bcc_common.cc b/src/cc/bcc_common.cc index 5c349d70d..c33e37afc 100644 --- a/src/cc/bcc_common.cc +++ b/src/cc/bcc_common.cc @@ -37,6 +37,10 @@ void * bpf_module_create_c_from_string(const char *text, unsigned flags, const c return mod; } +bool bpf_module_rw_engine_enabled() { + return ebpf::bpf_module_rw_engine_enabled(); +} + void bpf_module_destroy(void *program) { auto mod = static_cast<ebpf::BPFModule *>(program); if (!mod) return; diff --git a/src/cc/bcc_common.h b/src/cc/bcc_common.h index b5f77db92..ed68f543a 100644 --- a/src/cc/bcc_common.h +++ b/src/cc/bcc_common.h @@ -30,6 +30,7 @@ void * bpf_module_create_c(const char *filename, unsigned flags, const char *cfl void * bpf_module_create_c_from_string(const char *text, unsigned flags, const char *cflags[], int ncflags, bool allow_rlimit, const char *dev_name); +bool bpf_module_rw_engine_enabled(); void bpf_module_destroy(void *program); char * bpf_module_license(void *program); unsigned bpf_module_kern_version(void *program); diff --git a/src/python/bcc/libbcc.py b/src/python/bcc/libbcc.py index f9b83b3cb..076d84c35 100644 --- a/src/python/bcc/libbcc.py +++ b/src/python/bcc/libbcc.py @@ -26,6 +26,8 @@ lib.bpf_module_create_c_from_string.restype = ct.c_void_p lib.bpf_module_create_c_from_string.argtypes = [ct.c_char_p, ct.c_uint, ct.POINTER(ct.c_char_p), ct.c_int, ct.c_bool, ct.c_char_p] +lib.bpf_module_rw_engine_enabled.restype = ct.c_bool +lib.bpf_module_rw_engine_enabled.argtypes = None lib.bpf_module_destroy.restype = None lib.bpf_module_destroy.argtypes = [ct.c_void_p] lib.bpf_module_license.restype = ct.c_char_p diff --git a/tests/cc/test_bpf_table.cc b/tests/cc/test_bpf_table.cc index 2d5a56449..43bf28b00 100644 --- a/tests/cc/test_bpf_table.cc +++ b/tests/cc/test_bpf_table.cc @@ -21,7 +21,7 @@ #include "BPF.h" #include "catch.hpp" -TEST_CASE("test bpf table", "[bpf_table]") { +TEST_CASE("test bpf table", ebpf::bpf_module_rw_engine_enabled() ?

It's part of the logic that checks if kfunc and lsm programs are supported. Before this commit it used libbpf_find_vmlinux_btf_id(), this function calls btf__load_vmlinux_btf() that tries to load the BTF from different places, the canonical vmlinux in sysfs and other locations. This is not accurate as kfunc and lsm programs require to have the BTF file exposed directly by the kernel (CONFIG_DEBUG_INFO_BTF should be set). This commit updates that function to check if BTF is exposed directly by the kernel. This was causing opensnoop to try to use kfunc programs (instead of kprobes) in systems where they are not supported: $ ls /usr/lib/debug/boot/vmlinux-$(uname -r) /usr/lib/debug/boot/vmlinux-5.11.0-38-generic $ cat /boot/config-$(uname -r) | grep -i CONFIG_DEBUG_INFO_BTF $ sudo stat /sys/kernel/btf/vmlinux stat: cannot stat '/sys/kernel/btf/vmlinux': No such file or directory $ sudo python3 /usr/share/bcc/tools/opensnoop bpf: Failed to load program: Invalid argument Traceback (most recent call last): File "/usr/share/bcc/tools/opensnoop", line 321, in <module> b = BPF(text=bpf_text) File "/usr/lib/python3/dist-packages/bcc/__init__.py", line 483, in __init__ self._trace_autoload() File "/usr/lib/python3/dist-packages/bcc/__init__.py", line 1466, in _trace_autoload self.attach_kretfunc(fn_name=func_name) File "/usr/lib/python3/dist-packages/bcc/__init__.py", line 1140, in attach_kretfunc fn = self.load_func(fn_name, BPF.TRACING) File "/usr/lib/python3/dist-packages/bcc/__init__.py", line 522, in load_func raise Exception("Failed to load BPF program %s: %s" % Exception: Failed to load BPF program b'kretfunc____x64_sys_open': Invalid argument Fixes: 1ad2656a1d9c ("Add support_kfunc function to BPF object") Signed-off-by: Mauricio Vásquez <mauricio@kinvolk.io> --- src/cc/libbpf.c | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) diff --git a/src/cc/libbpf.c b/src/cc/libbpf.c index 63938eb54..e64032990 100644 --- a/src/cc/libbpf.c +++ b/src/cc/libbpf.c @@ -1350,7 +1350,16 @@ int bpf_attach_raw_tracepoint(int progfd, const char *tp_name) bool bpf_has_kernel_btf(void) { - return libbpf_find_vmlinux_btf_id("bpf_prog_put", 0) > 0; + struct btf *btf; + int err; + + btf = btf__parse_raw("/sys/kernel/btf/vmlinux"); + err = libbpf_get_error(btf); + if (err) + return false; + + btf__free(btf); + return true; } int kernel_struct_has_field(const char *struct_name, const char *field_name) From 8f40d6f57a8d94e7aee74ce358572d34d31b4ed4 Mon Sep 17 00:00:00 2001 From: Yonghong Song <yhs@fb.com> Date: Fri, 14 Jan 2022 09:26:33 -0800 Subject: [PATCH 0932/1261] update debian changelog for release v0.24.0 * Support for kernel up to 5.16 * bcc tools: update for trace.py, sslsniff.py, tcptop.py, hardirqs.py, etc. * new libbpf tools: bashreadline * allow specify wakeup_events for perf buffer * support BPF_MAP_TYPE_{INODE, TASK}_STORAGE maps * remove all deprecated libbpf function usage * remove P4/B language support * major test infra change, using github actions now * doc update, bug fixes and other tools improvement Signed-off-by: Yonghong Song <yhs@fb.com> --- debian/changelog | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/debian/changelog b/debian/changelog index 8a23841a4..220280400 100644 --- a/debian/changelog +++ b/debian/changelog @@ -1,3 +1,17 @@ +bcc (0.24.0-1) unstable; urgency=low + + * Support for kernel up to 5.16 + * bcc tools: update for trace.py, sslsniff.py, tcptop.py, hardirqs.py, etc. + * new libbpf tools: bashreadline + * allow specify wakeup_events for perf buffer + * support BPF_MAP_TYPE_{INODE, TASK}_STORAGE maps + * remove all deprecated libbpf function usage + * remove P4/B language support + * major test infra change, using github actions now + * doc update, bug fixes and other tools improvement + + -- Yonghong Song <ys114321@gmail.com> Wed, 14 Jan 2022 17:00:00 +0000 + bcc (0.23.0-1) unstable; urgency=low * Support for kernel up to 5.15 From 7db52aba311acb06610cdf89d8b524ceaae168d1 Mon Sep 17 00:00:00 2001 From: Barret Rhoden <brho@google.com> Date: Fri, 14 Jan 2022 13:59:28 -0500 Subject: [PATCH 0933/1261] libbpf-tools/klockstat: replace 'spin' with 'wait' Threads wait on mutexes; they don't spin.

If a BPF_SK_STORAGE map is pinned to bpffs, the map can be used in another bcc based process with BPF_TABLE_PINNED macro. #define BPF_TABLE_PINNED(_table_type, _key_type, _leaf_type, _name, _max_entries, _pinned) \ BPF_TABLE(_table_type ":" _pinned, _key_type, _leaf_type, _name, _max_entries) Miao Xu reported an issue such that the structure supporting BPF_TABLE does not have func pointer member sk_storage_get and sk_storage_delete and this may cause BPF program compilation failure. For example, without helpers.h change in this patch, the test case in this patch will have the following error: /virtual/main.c:14:22: error: no member named 'sk_storage_get' in 'struct sk_stg_table_t' val = sk_stg.sk_storage_get(sk, NULL, BPF_SK_STORAGE_GET_F_CREATE); To fix the above issue, we need to add sk_storage_get and sk_storage_delete to BPF_F_TABLE macro. I also added {task, inode}_storage_{get, delete} func pointer members to BPF_F_TABLE macro. Some other map macros like BPF_SOCKMAP, BPF_SOCKHASH, etc. also have special func pointer members. But I leave them for future patches if we have use cases for it.

After JITting an object file, the location and size of the section are considered to be "the function's insns". In order to support libbpf-style loading, we need to support its sec_def-style SEC() attributes e.g. SEC("tp_btf/softirq_entry"), which allow libbpf to determine the type of BPF prog - and often other information like where to attach - based on the section name. These are not guaranteed to be unique per function, so we can no longer assume that a section contains only one function. This commit gets rid of that assumption. bcc now finds the symbol in the JITed image matching each BPF prog function and uses it to determine size/location. Also, this commit only adds the ".bpf.fn.$FUNC_NAME" section attribute iff there isn't already a custom section attribute set.

However, since shared objects are page-aligned, when all of the probe locations have different page offsets, these offsets uniquely identify locations. Adjust Probe::usdt_getarg() to generate a switch on page offset if this is the case. If some locations have the same page offset, an instruction pointer switch is used, so this patch does not fully lift the restriction. However, it helps greatly with one-off investigations.

As a result these registers are showing up in probe descriptors on Fedora. pthread_start probe description on Ubuntu 20.04: ``` stapsdt 0x00000052 NT_STAPSDT (SystemTap probe descriptors) Provider: libpthread Name: pthread_start Location: 0x00000000000095e9, Base: 0x000000000001922c, Semaphore: 0x0000000000000000 Arguments: 8@%rax 8@1600(%rax) 8@1608(%rax) ``` And in the Fedora test container: ``` ``` stapsdt 0x00000053 NT_STAPSDT (SystemTap probe descriptors) Provider: libpthread Name: pthread_start Location: 0x0000000000009280, Base: 0x0000000000016cbc, Semaphore: 0x0000000000000000 Arguments: 8@%xmm0 8@1600(%rax) 8@1608(%rax) ``` bcc doesn't recognize these registers so it's unable to generate code to fetch arguments which use these registers for storage. Add support for XMM0-15. This should fix `lib/uthreads.py` test, which uses `pthread_start` and therefore fails to generate program on Fedora.

17:01:37 -0500 Subject: [PATCH 1009/1261] libbpf-tools: Add experimental integration with BTFGen MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit adds an experimental BTFGen[0] integration to allow some of the libbpf-tools to run in systems that don't provide BTF information. The whole process consist of two parts: (1) generating and embedding the BTF file within the tools binary and (2) using those when the tool is run. The first part is done by using the Makefile, it generates the reduced BTF files for the different eBPF objects of the tools, those files are then compressed and a C header file with its content is created. The second part is handled by a new C file that provides the logic to uncompress and save the BTF file according to the Linux distribution and kernel version where the tools is being run.

For example, when llvm decides to inline the latter into the former but not ignore the inline directive on the former, the underscored one doesn't exist and the one without can't be kprobed because it doesn't have the fentry call. Side step the whole thing by attaching to the block_rq_complete tracepoint. There's a slight disadvantage - it now needs its own bpf_ktime_get_ns() call. It will add some overhead on really high ops devices but it is what it is.

This happens because the filter_ports variable is declared using a ".rodata hack": SEC(".rodata") int filter_ports[MAX_PORTS] This breaks with the recent clang, as the filter_ports variable is placed into the '.rodata,aw' section. Older clang would put it into '.rodata,a' section where all 'const volatile' variables are placed. The result is that the filter_ports variable has a wrong offset of 0 in BTF_KIND_DATASEC. To hack the hack we can declare the variable as SEC(".rodata") const int filter_ports[MAX_PORTS] but, instead, we now can just declare it as const volatile int filter_ports[MAX_PORTS] In fact, this was already done in a02663be ("libbpf-tools: update bpftool and fix .rodata hack"), but a later commit f8ac3c6c ("libbpf-tools: fix tcpconnect compile errors") reverted the change without any comments.

Previous work (#1670) modified the "global address" -> "module offset" calculation in `ProcSyms::Module::contains` to account for differences between the file offset a section is loading bytes from and the requested start address (relative to the base address of the `.so`). Unfortunately that change didn't also modify "module offset" -> "global address" calculations, such as the one in bcc_resolve_global_addr. Update that calculation to account for the same. This calculation discrepancy was most apparent for us in production when trying to attach USDTs to a shared lib with differing requested start address and file offset. This patch also adds a test w/ comments describing our specific situation and demonstrating how the patch fixes the issue.

This can be useful to detect diverse memory mishandling. Case at hand here is the detection of a memory leak introduced in the past that went undetected for a while. Currently, it may not be possible to enable it as part of the bcc CI as there is a few existing leaks, but long term it may be beneficial to enable this as part of the CI si bus get caught early on. In the meantime, it is still valuable to be able to enable this in an ad-hoc manner.

This makes it complicated for libraries built on top of libbcc to be compatible across multiple versions when there is API changes for instances, as happens in https://github.com/iovisor/gobpf/pull/311 Exposing MAJOR/MINOR/PATCH versions would allow libraries which are not shipped as part of iovisor/bcc to handle those API changes. This diffs exposes those values, provides a macro to perform version comparison (a la `LINUX_VERSION()`). One thing it does not address currently is exposing whether this is an "exact tag" version, e.g a release, or in between releases.

This is because some existing users may have implicit memory accesses to access user memory, so using bpf_probe_read_kernel() will cause their applications to fail. In riscv64, we should use the new bpf_probe_read_{kernel|user} function instead of the old bpf_probe_read(). riscv64 does not have overlapping address spaces, but does not have ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE set like x86. And bpf_probe_read() is not available in RISCV64, so it will cause an error. This patch works fine to correctly use bpf_probe_read_{kernel|user}() on riscv64 until issues that may break existing user programs are resolved.

Add a new option -s (or --source-port) to display the source port when tracing, or to use the source port as part of the key when counting connections. This option is unset by default to provide the original output.

The catch framework allows to do this. See https://github.com/catchorg/Catch2/blob/devel/docs/command-line.md#specifying-which-tests-to-run When the wrapper was originally introduced, it used to pass the list of arguments to the tests as an array. For some reasons, it got changed in https://github.com/iovisor/bcc/commit/7009b559f390292b1ee4b3970aca88b2272c52fd#diff-29e66e11b6682a5b66d214c108dd3c351a557bc884b64946af004e0e3195d209 This diff, re-introduces passing the list of arguments as an array (`$@`).

But for `bcc_elf_get_buildid` which did not free the elf object, the rest of the leaks were isolated in the tests themselves which did not free some resources here and there. This diff clears those leaks. This will allow running the tests suite in the future with LSAN enabled, helping in catching possible future leaks earlier.

Now the problem is that when multiple arguments are passed, they all end up being within the same argument because they get wrapped within the double-quotes. This is pretty much an escape-hell as we keep on passing the same arguments over and over through functions and then within `bash -c`. The reason for the `bash -c` bit is that it allows us to set some envirtonment variable used in the tests. Those env var are set to the local environment values. Instead of going an extra layer of indirection, we can tell `sudo` to preserve those specific env var by using the `--preserve-env` argument this way, we do not have to re-escape the arguments that are passed within the `bash -c` quoted arg.

Encoding and python2/python3 is.... complicated. Those tests already run on py3 which is the default for Ubuntu Focal and Fedora 34. This change symlinks /usr/local/bin/python to python3 within the Bionic container and changes all tools to use "#!/usr/bin/env python" shebang instead of "#!/usr/bin/python" which allows to use the default python set by the environment. To add insult to injury. Python 3.6 still needs a bit of help to default to UTF-8 which can be achieved with the env var `PYTHONIOENCODING` to `utf-8`. Since python 3.7, [UTF-8 mode is enabled by default when the locale is C or POSIX](https://docs.python.org/3/whatsnew/3.7.html#whatsnew37-pep540). Some more details about this problem can be found here: https://vstinner.github.io/posix-locale.html#misconfigured-locales-in-docker-images Illustration: ``` root@bionic:/# locale LANG= LANGUAGE= LC_CTYPE="POSIX" LC_NUMERIC="POSIX" LC_TIME="POSIX" LC_COLLATE="POSIX" LC_MONETARY="POSIX" LC_MESSAGES="POSIX" LC_PAPER="POSIX" LC_NAME="POSIX" LC_ADDRESS="POSIX" LC_TELEPHONE="POSIX" LC_MEASUREMENT="POSIX" LC_IDENTIFICATION="POSIX" LC_ALL= root@bionic:/# python2 Python 2.7.17 (default, Jul 1 2022, 15:56:32) [GCC 7.5.0] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> print("%s" % u'\xb7') Traceback (most recent call last): File "<stdin>", line 1, in <module> UnicodeEncodeError: 'ascii' codec can't encode character u'\xb7' in position 0: ordinal not in range(128) >>> root@bionic:/# python3 Python 3.6.9 (default, Jun 29 2022, 11:45:57) [GCC 8.4.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> print("%s" % u'\xb7') Traceback (most recent call last): File "<stdin>", line 1, in <module> UnicodeEncodeError: 'ascii' codec can't encode character '\xb7' in position 0: ordinal not in range(128) >>> root@bionic:/# PYTHONIOENCODING=utf-8 python3 Python 3.6.9 (default, Jun 29 2022, 11:45:57) [GCC 8.4.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> print("%s" % u'\xb7') · ``` On Focal: ``` root@focal:/# locale LANG= LANGUAGE= LC_CTYPE="POSIX" LC_NUMERIC="POSIX" LC_TIME="POSIX" LC_COLLATE="POSIX" LC_MONETARY="POSIX" LC_MESSAGES="POSIX" LC_PAPER="POSIX" LC_NAME="POSIX" LC_ADDRESS="POSIX" LC_TELEPHONE="POSIX" LC_MEASUREMENT="POSIX" LC_IDENTIFICATION="POSIX" LC_ALL= root@focal:/# python3 Python 3.8.10 (default, Jun 22 2022, 20:18:18) [GCC 9.4.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> print("%s" % u'\xb7') · ``` --- docker/Dockerfile.tests | 1 + tests/wrapper.sh.in | 7 ++++--- tools/argdist.py | 2 +- tools/bashreadline.py | 2 +- tools/bindsnoop.py | 2 +- tools/biolatency.py | 2 +- tools/biolatpcts.py | 2 +- tools/biopattern.py | 2 +- tools/biosnoop.py | 2 +- tools/biotop.py | 2 +- tools/bitesize.py | 2 +- tools/bpflist.py | 2 +- tools/btrfsdist.py | 2 +- tools/btrfsslower.py | 2 +- tools/cachestat.py | 2 +- tools/cachetop.py | 2 +- tools/capable.py | 2 +- tools/compactsnoop.py | 2 +- tools/cpudist.py | 2 +- tools/cpuunclaimed.py | 2 +- tools/criticalstat.py | 2 +- tools/dbslower.py | 2 +- tools/dbstat.py | 2 +- tools/dcsnoop.py | 2 +- tools/dcstat.py | 2 +- tools/deadlock.py | 2 +- tools/dirtop.py | 2 +- tools/drsnoop.py | 2 +- tools/execsnoop.py | 2 +- tools/exitsnoop.py | 2 +- tools/ext4dist.py | 2 +- tools/ext4slower.py | 2 +- tools/filelife.py | 2 +- tools/fileslower.py | 2 +- tools/filetop.py | 2 +- tools/funccount.py | 2 +- tools/funcinterval.py | 2 +- tools/funclatency.py | 2 +- tools/funcslower.py | 2 +- tools/gethostlatency.py | 2 +- tools/hardirqs.py | 2 +- tools/inject.py | 2 +- tools/killsnoop.py | 2 +- tools/klockstat.py | 2 +- tools/llcstat.py | 2 +- tools/mdflush.py | 2 +- tools/memleak.py | 2 +- tools/mountsnoop.py | 2 +- tools/mysqld_qslower.py | 2 +- tools/netqtop.py | 2 +- tools/nfsdist.py | 2 +- tools/nfsslower.py | 2 +- tools/offcputime.py | 2 +- tools/offwaketime.py | 2 +- tools/oomkill.py | 2 +- tools/opensnoop.py | 2 +- tools/pidpersec.py | 2 +- tools/profile.py | 2 +- tools/readahead.py | 2 +- tools/runqlat.py | 2 +- tools/runqlen.py | 2 +- tools/runqslower.py | 2 +- tools/shmsnoop.py | 2 +- tools/slabratetop.py | 2 +- tools/sofdsnoop.py | 2 +- tools/softirqs.py | 2 +- tools/solisten.py | 2 +- tools/sslsniff.py | 2 +- tools/stackcount.py | 2 +- tools/statsnoop.py | 2 +- tools/swapin.py | 2 +- tools/syncsnoop.py | 2 +- tools/syscount.py | 2 +- tools/tcpaccept.py | 2 +- tools/tcpcong.py | 2 +- tools/tcpconnect.py | 2 +- tools/tcpconnlat.py | 2 +- tools/tcpdrop.py | 2 +- tools/tcplife.py | 2 +- tools/tcpretrans.py | 2 +- tools/tcprtt.py | 2 +- tools/tcpstates.py | 2 +- tools/tcpsubnet.py | 2 +- tools/tcpsynbl.py | 2 +- tools/tcptop.py | 2 +- tools/tcptracer.py | 2 +- tools/threadsnoop.py | 2 +- tools/tplist.py | 2 +- tools/trace.py | 2 +- tools/ttysnoop.py | 2 +- tools/vfscount.py | 2 +- tools/vfsstat.py | 2 +- tools/virtiostat.py | 2 +- tools/wakeuptime.py | 2 +- tools/xfsdist.py | 2 +- tools/xfsslower.py | 2 +- tools/zfsdist.py | 2 +- tools/zfsslower.py | 2 +- 98 files changed, 101 insertions(+), 99 deletions(-) diff --git a/docker/Dockerfile.tests b/docker/Dockerfile.tests index 28965c446..8a490b45f 100644 --- a/docker/Dockerfile.tests +++ b/docker/Dockerfile.tests @@ -72,3 +72,4 @@ RUN wget -O ruby-install-0.7.0.tar.gz \ RUN ruby-install --system ruby 2.6.0 -- --enable-dtrace RUN if [ !

The reason is due to code zone - zone_pgdat->node_zones where zone and zone_pgdat->node_zones are pointers to struct zone (with size 1664). So effectively the above is equivalent to ((void *)zone - (void *)zone_pgdat->node_zones)/sizeof(struct zone) which is converted to sdiv insn. llvm11 seems okay and I didn't investigate why. But llvm14 and latest llvm16 failed with compiler fatal error. To fix the issue let us replace the above '(void *)' as '(u64)' and then the udiv will be used for the division.

The TL;DR is that the implementation of `os.popen` change somewhere between python 3.9 and 3.10 and depending on which version of python is used, either `fork/clone` is called, or `vfork`. In both cases, we are going to end up calling `execve`. This change switches the syscall traced from `clone` to `execve`. At the same time, it is now a constant that can be used across the tests.

Failing to do so, we would need to: 1) land the docker file change in order to incorporate the change 2) land the charge that uses this new dockerfile change This is cumbersome and it is hard to make sure that changes to the dockerfile are indeed correct. This change conditionally pull the pre-built image if no dockerfile change happened. Otherwise it reuses the "build_container" action to build the image. This commit should confirm that we indeed pull when no dockerfile are changed. A subsequent commit will modify a Dockerfile and confirm that in that case, we indeed build the container. --- .github/workflows/bcc-test.yml | 48 ++++++++++++++++++++++++---------- 1 file changed, 34 insertions(+), 14 deletions(-) diff --git a/.github/workflows/bcc-test.yml b/.github/workflows/bcc-test.yml index 898039f5c..bcf10275f 100644 --- a/.github/workflows/bcc-test.yml +++ b/.github/workflows/bcc-test.yml @@ -30,19 +30,29 @@ jobs: RW_ENGINE_ENABLED: ON steps: - uses: actions/checkout@v2 + - uses: dorny/paths-filter@v2 + id: changes + with: + filters: | + docker: + - 'docker/build/**' - name: System info run: | uname -a ip addr - - name: Log into registry ${{ env.REGISTRY }} - uses: docker/login-action@v2 - with: - registry: ${{ env.REGISTRY }} - username: ${{ github.actor }} - password: ${{ secrets.GITHUB_TOKEN }} - - name: Pull and tag docker container + - name: Pull docker container + if: steps.changes.outputs.docker == 'false' run: | docker pull ${{ env.REGISTRY }}/${{ env.IMAGE_NAME }}:${{ matrix.os.distro }}-${{ matrix.os.version }} + - name: Build docker container + if: steps.changes.outputs.docker == 'true' + uses: ./.github/actions/build-container + with: + os_distro: ${{ matrix.os.distro }} + os_version: ${{ matrix.os.version }} + os_nick: ${{ matrix.os.nick }} + - name: Tag docker container + run: | docker tag ${{ env.REGISTRY }}/${{ env.IMAGE_NAME }}:${{ matrix.os.distro }}-${{ matrix.os.version }} bcc-docker - name: Run bcc build env: ${{ matrix.env }} @@ -121,19 +131,29 @@ jobs: PYTHON_TEST_LOGFILE: critical.log steps: - uses: actions/checkout@v2 + - uses: dorny/paths-filter@v2 + id: changes + with: + filters: | + docker: + - 'docker/build/**' - name: System info run: | uname -a ip addr - - name: Log into registry ${{ env.REGISTRY }} - uses: docker/login-action@v2 - with: - registry: ${{ env.REGISTRY }} - username: ${{ github.actor }} - password: ${{ secrets.GITHUB_TOKEN }} - - name: Pull and tag docker container + - name: Pull docker container + if: steps.changes.outputs.docker == 'false' run: | docker pull ${{ env.REGISTRY }}/${{ env.IMAGE_NAME }}:${{ matrix.os.distro }}-${{ matrix.os.version }} + - name: Build docker container + if: steps.changes.outputs.docker == 'true' + uses: ./.github/actions/build-container + with: + os_distro: ${{ matrix.os.distro }} + os_version: ${{ matrix.os.version }} + os_nick: ${{ matrix.os.nick }} + - name: Tag docker container + run: | docker tag ${{ env.REGISTRY }}/${{ env.IMAGE_NAME }}:${{ matrix.os.distro }}-${{ matrix.os.version }} bcc-docker - name: Run bcc build env: ${{ matrix.env }} From 0393eba198bcf3c413bb91398ac1881ef525c78c Mon Sep 17 00:00:00 2001 From: chantra <chantr4@gmail.com> Date: Tue, 6 Sep 2022 23:09:02 +0000 Subject: [PATCH 1202/1261] [docker] Fix tabs in Dockerfile.fedora My editor was expanding tabs to spaces when other lines seem to be using pure tabs.

The problem is that we cannot differenciate between a test failing because some tooling is missing, or tests legitimately failing. This diff creates a new decorator that will skip a test if some binaries are not present, therefore, if the binaries are there and there is any issue, CI will fail. It will generate a message similar to: ``` docker run -ti \ --privileged \ --network=host \ --pid=host \ -v $(pwd):/bcc \ -v /sys/kernel/debug:/sys/kernel/debug:rw \ -v /lib/modules:/lib/modules:ro \ -v /usr/src:/usr/src:ro \ -e CTEST_OUTPUT_ON_FAILURE=1 \ u34 \ /bin/bash -c \ '/bcc/build/tests/wrapper.sh "py_test_percpu" "sudo" "/bcc/tests/python/test_brb.py" test_brb.c -v' test_brb (__main__.TestBPFSocket) ... skipped 'Missing binaries: neperf, neterver. iperf and netperf packages must be installed.' ---------------------------------------------------------------------- Ran 1 test in 0.000s OK (skipped=1) ``` --- tests/python/utils.py | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/tests/python/utils.py b/tests/python/utils.py index b1a7d2638..40e7b157d 100644 --- a/tests/python/utils.py +++ b/tests/python/utils.py @@ -2,6 +2,7 @@ from distutils.spawn import find_executable import traceback import distutils.version +import shutil import logging, os, sys @@ -51,6 +52,23 @@ def wrapper(*args, **kwargs): return wrapper return decorator +# This is a decorator that will skip tests if any binary in the list is not in PATH. +def skipUnlessHasBinaries(binaries, message): + def decorator(func): + def wrapper(self, *args, **kwargs): + missing = [] + for binary in binaries: + if shutil.which(binary) is None: + missing.append(binary) + + if len(missing): + missing_binaries = ", ".join(missing) + self.skipTest(f"Missing binaries: {missing_binaries}. {message}") + else: + func(self, *args, **kwargs) + return wrapper + return decorator + class NSPopenWithCheck(NSPopen): """ A wrapper for NSPopen that additionally checks if the program From bfc8252a07165b95cb13c27ab9cf1040257f7368 Mon Sep 17 00:00:00 2001 From: chantra <chantr4@gmail.com> Date: Thu, 1 Sep 2022 23:38:06 +0000 Subject: [PATCH 1206/1261] [test][test_brb] Gate the test behind the new skipUnlessHasBinaries decorator If we have the binaries on file, we should fail and report the failure.

Because of loop unrolling is often hard to reliably apply in practice: On the one hand because loops in code is not always easy to formalize: https://llvm.org/docs/LoopTerminology.html On the other hand, loop unrolling in clang/llvm often is not forcible because of the complexity of code generation and optimization. Bounded loop allows more reliable verification on BPF code that uses compile-time constants as loop termination conditions. Therefore substantially simplified the writing of BPF code. --- docs/kernel-versions.md | 1 + 1 file changed, 1 insertion(+) diff --git a/docs/kernel-versions.md b/docs/kernel-versions.md index bd83b92d2..bb1fe8982 100644 --- a/docs/kernel-versions.md +++ b/docs/kernel-versions.md @@ -82,6 +82,7 @@ BPF flow dissector | 4.20 | [`d58e468b1112`](https://github.com/torvalds/linux/c BPF 1M insn limit | 5.2 | [`c04c0d2b968a`](https://github.com/torvalds/linux/commit/c04c0d2b968ac45d6ef020316808ef6c82325a82) BPF cgroup sysctl | 5.2 | [`7b146cebe30c`](https://github.com/torvalds/linux/commit/7b146cebe30cb481b0f70d85779da938da818637) BPF raw tracepoint writable | 5.2 | [`9df1c28bb752`](https://github.com/torvalds/linux/commit/9df1c28bb75217b244257152ab7d788bb2a386d0) +BPF bounded loop | 5.3 | [`2589726d12a1`](https://github.com/torvalds/linux/commit/2589726d12a1b12eaaa93c7f1ea64287e383c7a5) BPF trampoline | 5.5 | [`fec56f5890d9`](https://github.com/torvalds/linux/commit/fec56f5890d93fc2ed74166c397dc186b1c25951) BPF LSM hook | 5.7 | [`fc611f47f218`](https://github.com/torvalds/linux/commit/fc611f47f2188ade2b48ff6902d5cce8baac0c58) [`641cd7b06c91`](https://github.com/torvalds/linux/commit/641cd7b06c911c5935c34f24850ea18690649917) BPF iterator | 5.8 | [`180139dca8b3`](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=180139dca8b38c858027b8360ee10064fdb2fbf7) From 79bf9786508254e3d87fc00e9a7321ac5e453355 Mon Sep 17 00:00:00 2001 From: Francis Laniel <flaniel@linux.microsoft.com> Date: Thu, 3 Mar 2022 22:19:34 +0100 Subject: [PATCH 1209/1261] libbpf-tools: Add tcptop tool. tcptop is a simple program that traces sent and received bytes over IP and print them like top.

With libbpf built via git submodule, the uapi header included in the libbpf package is used, so here a similar approach is proposed for the external package build. Instead of having to sync another file the already present compat/linux/virtual_bpf.h is used; we copy it to compat/linux/bpf.h (eliminating the string prefix/suffix on first/last lines). From there, we ensure that places that assume the presence of the libbpf git submodule point at compat/ as a location to find the uapi header.

The workload of target platform is running auto test script and launching lots of applications periodically on Android TV. There are several abnormal records of run queue latency, ex. 1311763801. We have investgated this issue and found the root cuase of this issue is the hash map to store en-queue start time of each task overflowed, and it seems cpudist also encountered such issue before and fix by following pull request. https://github.com/iovisor/bcc/pull/2568 Apply the similar fix to runqslower, getting the max_pid from /proc/sys/kernel/max_pid and pass to BPF C in kernel to create enough entries of BPF map to store en-queue start time of each task. In the mean time, since we create the BPF map with max_pid entries, use BPF_ARRAY instead of BPF_HASH to prevent collision. ``` (bcc)root@localhost:/# runqslower 100000 -P Tracing run queue latency higher than 100000 us TIME COMM TID LAT(us) PREV COMM PREV TID 23:42:45 glide-source-th 28986 161605 kworker/u9:3 12260 23:42:50 HTTPREQUEST_MAN 26249 107187 OMX_VideoInput 7152 23:42:50 migration/2 24 146799 OmxSideband 7147 23:42:50 rtk_post_worker 128 174145 migration/2 24 23:42:50 Binder:233_4 633 170457 runqslower 7086 23:42:58 GIBBON_SURFACE_ 26233 103377 composer@2.4-se 457 23:43:14 Binder:581_1B 2202 113153 Binder:581_7 833 23:43:24 migration/0 15 107716 writer 7277 .... 05:08:14 dumpLogs.sh 22242 1311763801 NBP_POOL-[1] 24233 05:08:14 dumpLogs.sh 22243 1311752373 appsrc7:src 24281 05:08:14 dumpLogs.sh 22248 1311760825 dumpLogs.sh 22193 ``` Signed-off-by: Ism Hong <ism.hong@realtek.com> --- tools/runqslower.py | 14 ++++++++------ 1 file changed, 8 insertions(+), 6 deletions(-) diff --git a/tools/runqslower.py b/tools/runqslower.py index 0ef5cb1ab..1700f1bf8 100755 --- a/tools/runqslower.py +++ b/tools/runqslower.py @@ -74,7 +74,7 @@ #include <linux/nsproxy.h> #include <linux/pid_namespace.h> -BPF_HASH(start, u32);

This causes the argument parser to fail: Parse error: 8@x22 8@x20 8@x23 8@x0 8@x26 8@x27 8@[sp, 112] 8@[sp, 120] ------------------------------------------^ The error message then repeats forever. Changed ArgumentParser_aarch64::parse_register so it accepts either "xNN" or "sp" and outputs the register name rather than the register number. The stack pointer is in a separate field `sp` in `struct pt_regs` rather than in the `regs[]` array [1]. Note that the parser currently accepts "x31" and converts that into a reference to `regs[31]' but that array only has 31 elements. Made x31 an alias for `sp` to avoid undefined behaviour from reading past the end of the array.

This patch contains re-generated vmlinux.h from kernel built with default config plus minimal changes to enable most (all?) BPF-relevant parts of kernel. Here's a list of added options: CONFIG_BPF_EVENTS=y CONFIG_BPFILTER_UMH=m CONFIG_BPFILTER=y CONFIG_BPF_JIT=y CONFIG_BPF_KPROBE_OVERRIDE=y CONFIG_BPF_STREAM_PARSER=y CONFIG_BPF_SYSCALL=y CONFIG_CC_HAS_ASM_INLINE=y CONFIG_CC_HAS_KASAN_GENERIC=y CONFIG_CC_HAS_SANCOV_TRACE_PC=y CONFIG_CGROUP_BPF=y CONFIG_GCC_VERSION=70300 CONFIG_IPV6_MULTIPLE_TABLES=y CONFIG_IPV6_SEG6_BPF=y CONFIG_IPV6_SEG6_LWTUNNEL=y CONFIG_LIBCRC32C=y CONFIG_LWTUNNEL_BPF=y CONFIG_LWTUNNEL=y CONFIG_NET_ACT_BPF=y CONFIG_NET_CLS_BPF=y CONFIG_NETFILTER_ADVANCED=y CONFIG_NETFILTER_XT_MATCH_BPF=y CONFIG_NET_SOCK_MSG=y CONFIG_NF_CT_PROTO_DCCP=y CONFIG_NF_CT_PROTO_SCTP=y CONFIG_NF_CT_PROTO_UDPLITE=y CONFIG_SOCK_CGROUP_DATA=y CONFIG_STREAM_PARSER=y CONFIG_XDP_SOCKETS_DIAG=y CONFIG_XDP_SOCKETS=y To make this vmlinux.h generation process easier for future adjustments (e.g., if some of the tools would need types that default config compiles out), check in used Kconfig along the vmlinux.h itself.

automated tests for it. Following patches are adding automated test for this function and it seems too much to link in all the clang/llvm stuff to the test binary just for single function test. Adding ebpf::parse_tracepoint that takes istream of the tracepoint format data and returns tracepoint struct as std::string. No functional change is intended or expected.

Two new 'common_' fields were added and it causes 2 issues for tracepoint format parser. First issue - is the gap between common fields and other fields, which is not picked up by the parser, so the resulted struct is not aligned with the data. Second issue - is the fact that current parser covers common fields with: u64 __do_not_use__ so the new common fields are not accounted for. This issue is solved in the following patch. I kept both issues and fixes separated to make the change readable. There's a 'not described gap' in the sched_wakeup's format file and probably in other formats as well: Having: # cat /sys/kernel/debug/tracing/events/sched/sched_wakeup/format name: sched_wakeup ID: 310 format: field:unsigned short common_type; offset:0; size:2; signed:0; field:unsigned char common_flags; offset:2; size:1; signed:0; field:unsigned char common_preempt_count; offset:3; size:1; signed:0; field:int common_pid; offset:4; size:4; signed:1; field:unsigned char common_migrate_disable; offset:8; size:1; signed:0; field:unsigned char common_preempt_lazy_count; offset:9; size:1; signed:0; field:char comm[16]; offset:12; size:16; signed:1; field:pid_t pid; offset:28; size:4; signed:1; field:int prio; offset:32; size:4; signed:1; field:int success; offset:36; size:4; signed:1; field:int target_cpu; offset:40; size:4; signed:1; There's "common_preempt_lazy_count" field on offset 9 with size 1: common_preempt_lazy_count; offset:9; size:1; and it's followed by "comm" field on offset 12: field:char comm[16]; offset:12; size:16; signed:1; which makes 2 bytes gap in between, that might confuse some applications like bpftrace or bcc-tools library. The tracepoint parser makes struct out of the field descriptions, but does not account for such gaps. I posted patch to fix this [1] in RT kernel, but that might take a while, and we could easily fix our tracepoint parser to workaround this issue. Adding code to detect this gaps and add 1 byte __pad_X fields, where X is the offset number.

Keeping the 'u64 __do_not_use__' field for backward compatibility (who knows who's actualy using it) and adding new fields, like: char __do_not_use__X for each byte of extra common fields, where X is the offset of the field. With this fix the bcc-tools correctly parses tracepoints on RT kernel and it's usable again.

Quoting https://refspecs.linuxbase.org/elf/elf.pdf: ``` Symbol table entries for different object file types have slightly different interpretations for the st_value member. - In relocatable files, st_value holds alignment constraints for a symbol whose section index is SHN_COMMON. - In relocatable files, st_value holds a section offset for a defined symbol. That is, st_value is an offset from the beginning of the section that st_shndx identifies. - In executable and shared object files, st_value holds a virtual address. To make these files' symbols more useful for the dynamic linker, the section offset (file interpretation) gives way to a virtual address (memory interpretation) for which the section number is irrelevant. ``` This is a problem in practice as well. I run into this while tracing shared libraries on Android with bpftrace. Some of them have text sections mmapped at different offset than file offset which results in probes being placed at wrong offsets. --- src/cc/bcc_syms.cc | 10 ++++---- tests/python/CMakeLists.txt | 2 ++ tests/python/test_uprobes2.py | 47 +++++++++++++++++++++++++++++++++++ 3 files changed, 54 insertions(+), 5 deletions(-) create mode 100755 tests/python/test_uprobes2.py diff --git a/src/cc/bcc_syms.cc b/src/cc/bcc_syms.cc index fe9853df2..49439f43d 100644 --- a/src/cc/bcc_syms.cc +++ b/src/cc/bcc_syms.cc @@ -707,6 +707,7 @@ int bcc_resolve_symname(const char *module, const char *symname, const uint64_t addr, int pid, struct bcc_symbol_option *option, struct bcc_symbol *sym) { + int module_type; static struct bcc_symbol_option default_option = { .use_debug_file = 1, .check_debug_file_crc = 1, @@ -747,11 +748,10 @@ int bcc_resolve_symname(const char *module, const char *symname, if (sym->offset == 0x0) goto invalid_module; - // For executable (ET_EXEC) binaries, translate the virtual address - // to physical address in the binary file. - // For shared object binaries (ET_DYN), the address from symbol table should - // already be physical address in the binary file. - if (bcc_elf_get_type(sym->module) == ET_EXEC) { + // For executable (ET_EXEC) binaries and shared objects (ET_DYN), translate + // the virtual address to physical address in the binary file. + module_type = bcc_elf_get_type(sym->module); + if (module_type == ET_EXEC || module_type == ET_DYN) { struct load_addr_t addr = { .target_addr = sym->offset, .binary_addr = 0x0, diff --git a/tests/python/CMakeLists.txt b/tests/python/CMakeLists.txt index 63a341305..67b3303c9 100644 --- a/tests/python/CMakeLists.txt +++ b/tests/python/CMakeLists.txt @@ -55,6 +55,8 @@ add_test(NAME py_array WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} COMMAND ${TEST_WRAPPER} py_array sudo ${CMAKE_CURRENT_SOURCE_DIR}/test_array.py) add_test(NAME py_uprobes WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} COMMAND ${TEST_WRAPPER} py_uprobes sudo ${CMAKE_CURRENT_SOURCE_DIR}/test_uprobes.py) +add_test(NAME py_uprobes_2 WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} + COMMAND ${TEST_WRAPPER} py_uprobes2 sudo ${CMAKE_CURRENT_SOURCE_DIR}/test_uprobes2.py) add_test(NAME py_test_stackid WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} COMMAND ${TEST_WRAPPER} py_stackid sudo ${CMAKE_CURRENT_SOURCE_DIR}/test_stackid.py) add_test(NAME py_test_tracepoint WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} diff --git a/tests/python/test_uprobes2.py b/tests/python/test_uprobes2.py new file mode 100755 index 000000000..6118754a6 --- /dev/null +++ b/tests/python/test_uprobes2.py @@ -0,0 +1,47 @@ +#!/usr/bin/env python +# +# USAGE: test_uprobe2.py +# +# Copyright 2020 Facebook, Inc +# Licensed under the Apache License, Version 2.0 (the "License") + +from bcc import BPF +from unittest import main, TestCase +from subprocess import Popen, PIPE +from tempfile import NamedTemporaryFile + + +class TestUprobes(TestCase): + def setUp(self): + lib_text = b""" +__attribute__((__visibility__("default"))) void fun() +{ +} +""" + self.bpf_text = """ +int trace_fun_call(void *ctx) {{ + return 1; +}} +""" + # Compile and run the application + self.ftemp = NamedTemporaryFile(delete=False) + self.ftemp.close() + comp = Popen([ + "gcc", + "-x", "c", + "-shared", + "-Wl,-Ttext-segment,0x2000000", + "-o", self.ftemp.name, + "-" + ], stdin=PIPE) + comp.stdin.write(lib_text) + comp.stdin.close() + self.assertEqual(comp.wait(), 0) + + def test_attach1(self): + b = BPF(text=self.bpf_text) + b.attach_uprobe(name=self.ftemp.name, sym="fun", fn_name="trace_fun_call") + + +if __name__ == "__main__": + main() From 5057bbe6fb00a112c03ac5c5277646fd9602c1b1 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Sun, 5 Apr 2020 18:21:26 -0400 Subject: [PATCH 0305/1261] examples/tracing: add io_latencies - IO latency distribution monitor This adds flexible low overhead latency percentile monitoring for block devices which can be useful in understanding and debugging IO related issues.

It is expected that any C preprocessor that conforms to the ELF ABI v2 specification must predefine the _CALL_ELF macro and set its value to 2. Instead of looking at __BYTE_ORDER__ to determine whether to use the Local Entry Point (LEP) of symbols, one should look at the _CALL_ELF macro instead as this is ABI-related. Similarly, _CALL_ELF should be used only for determining the ABI version and not the endianness. Reported-by: Naveen N.

Hence separation of bpf_probe_read_user and bpf_probe_read_kernel is essential. Commit 6ae08ae3dea2 ("bpf: Add probe_read_{user, kernel} and probe_read_{user, kernel}_str helpers") introduced these changes into the kernel. However, bcc tools does not respect it. As a workaround, perform the following: 1. Use bpf_probe_read_user() explicitly in the bcc tools. 2. When kernel version < 5.5, perform the checks if the bpf_probe_read_user kernel helper is present in the backported kernel as well. If not found, then fallback from bpf_probe_read_user to bpf_probe_read.

Commit fa697140f9a2 ("syscalls/x86: Use 'struct pt_regs' based syscall calling convention for 64-bit syscalls") changed the raw parameter passed to the syscall entry function from a list of parameters supplied in user space to a single `pt_regs *` parameter (ARCH_HAS_SYSCALL_WRAPPER) 2. But ARCH_HAS_SYSCALL_WRAPPER in s390 is not used for that purpose. See commit a18f03cd89e9 ("s390: autogenerate compat syscall wrappers") 3.

That's a clone of filetop but works in a different way : - user specify a set of globs to select a list of directories to watch - dirtop extracts the inode_id of the selected directories - the bpf program receives the list of top directories to consider - when vfs_{read|write} occurs, the bpf program check if one of the parents is part of the list we search for - if it matches, the io is accounted On the python side, the program will reconcilate IOs per directory and print stats. While filetop list the programs and filename, dirtop only list the directory name.

[\-h] [\-C] [\-r MAXROWS] [\-s {reads,writes,rbytes,wbytes}] [\-p PID] [interval] [count] +.SH DESCRIPTION +This is top for directories. + +This traces file reads and writes, and prints a per-directory summary every interval +(by default, 1 second). By default the summary is sorted on the highest read +throughput (Kbytes). Sorting order can be changed via -s option. + +This uses in-kernel eBPF maps to store per process summaries for efficiency. + +This script works by tracing the __vfs_read() and __vfs_write() functions using +kernel dynamic tracing, which instruments explicit read and write calls. If +files are read or written using another means (eg, via mmap()), then they +will not be visible using this tool. Also, this tool will need updating to +match any code changes to those vfs functions. + +This should be useful for file system workload characterization when analyzing +the performance of applications. + +Note that tracing VFS level reads and writes can be a frequent activity, and +this tool can begin to cost measurable overhead at high I/O rates. + +Since this uses BPF, only the root user can use this tool. +.SH REQUIREMENTS +CONFIG_BPF and bcc. +.SH OPTIONS +.TP +\-d +Defines a list of directories, comma separated, to observe. +Wildcards are allowed if between single bracket. +.TP +\-C +Don't clear the screen. +.TP +\-r MAXROWS +Maximum number of rows to print. Default is 20. +.TP +\-s {reads,writes,rbytes,wbytes} +Sort column. Default is rbytes (read throughput). +.TP +\-p PID +Trace this PID only. +.TP +interval +Interval between updates, seconds. +.TP +count +Number of interval summaries. + +.SH EXAMPLES +.TP +Summarize block device I/O by directory, 1 second screen refresh: +# +.B dirtop.py +.TP +Don't clear the screen, and top 8 rows only: +# +.B dirtop.py -Cr 8 +.TP +5 second summaries, 10 times only: +# +.B dirtop.py 5 10 +.TP +Report read & write IOs generated in mutliple yarn and data directories: +# +.B dirtop.py -d '/hdfs/uuid/*/yarn,/hdfs/uuid/*/data' +.SH FIELDS +.TP +loadavg: +The contents of /proc/loadavg +.TP +READS +Count of reads during interval. +.TP +WRITES +Count of writes during interval. +.TP +R_Kb +Total read Kbytes during interval. +.TP +W_Kb +Total write Kbytes during interval. +.TP +PATH +The path were the IOs were accounted. +.SH OVERHEAD +Depending on the frequency of application reads and writes, overhead can become +significant, in the worst case slowing applications by over 50%. Hopefully for +real world workloads the overhead is much less -- test before use. The reason +for the high overhead is that VFS reads and writes can be a frequent event, and +despite the eBPF overhead being very small per event, if you multiply this +small overhead by a million events per second, it becomes a million times +worse. Literally. You can gauge the number of reads and writes using the +vfsstat(8) tool, also from bcc. +.SH SOURCE +This is from bcc. +.IP +https://github.com/iovisor/bcc +.PP +Also look in the bcc distribution for a companion _examples.txt file containing +example usage, output, and commentary for this tool. +.SH OS +Linux +.SH STABILITY +Unstable - in development. +.SH AUTHOR +Erwan Velu +.SH INSPIRATION +filetop(8) by Brendan Gregg +.SH SEE ALSO +vfsstat(8), vfscount(8), fileslower(8) diff --git a/tools/dirtop.py b/tools/dirtop.py new file mode 100755 index 000000000..d7c9e0c75 --- /dev/null +++ b/tools/dirtop.py @@ -0,0 +1,264 @@ +#!/usr/bin/python +# @lint-avoid-python-3-compatibility-imports +# +# dirtop file reads and writes by directory. +# For Linux, uses BCC, eBPF. +# +# USAGE: dirtop.py -d 'directory1,directory2' [-h] [-C] [-r MAXROWS] [interval] [count] +# +# This uses in-kernel eBPF maps to store per process summaries for efficiency. +# +# Copyright 2016 Netflix, Inc. +# Licensed under the Apache License, Version 2.0 (the "License") +# +# 13-Mar-2020 Erwan Velu Created dirtop from filetop +# 06-Feb-2016 Brendan Gregg Created filetop. + +from __future__ import print_function +from bcc import BPF +from time import sleep, strftime +import argparse +import os +import stat +from subprocess import call + +# arguments +examples = """examples: + ./dirtop -d '/hdfs/uuid/*/yarn' # directory I/O top, 1 second refresh + ./dirtop -d '/hdfs/uuid/*/yarn' -C # don't clear the screen + ./dirtop -d '/hdfs/uuid/*/yarn' 5 # 5 second summaries + ./dirtop -d '/hdfs/uuid/*/yarn' 5 10 # 5 second summaries, 10 times only + ./dirtop -d '/hdfs/uuid/*/yarn,/hdfs/uuid/*/data' # Running dirtop on two set of directories +""" +parser = argparse.ArgumentParser( + description="File reads and writes by process", + formatter_class=argparse.RawDescriptionHelpFormatter, + epilog=examples) +parser.add_argument("-C", "--noclear", action="store_true", + help="don't clear the screen") +parser.add_argument("-r", "--maxrows", default=20, + help="maximum rows to print, default 20") +parser.add_argument("-s", "--sort", default="all", + choices=["all", "reads", "writes", "rbytes", "wbytes"], + help="sort column, default all") +parser.add_argument("-p", "--pid", type=int, metavar="PID", dest="tgid", + help="trace this PID only") +parser.add_argument("interval", nargs="?", default=1, + help="output interval, in seconds") +parser.add_argument("count", nargs="?", default=99999999, + help="number of outputs") +parser.add_argument("--ebpf", action="store_true", + help=argparse.SUPPRESS) +parser.add_argument("-d", "--root-directories", type=str, required=True, dest="rootdirs", + help="select the directories to observe, separated by commas") +args = parser.parse_args() +interval = int(args.interval) +countdown = int(args.count) +maxrows = int(args.maxrows) +clear = not int(args.noclear) +debug = 0 + +# linux stats +loadavg = "/proc/loadavg" + +# define BPF program +bpf_text = """ +# include +# include + +// the key for the output summary +struct info_t { + unsigned long inode_id;

Although this approach works fine with systemd services and containers when cgroup-v2 is enabled, it does not work with containers when only cgroup-v1 is enabled because bpf_get_current_cgroup_id() only works with cgroup-v2. It also requires Linux 4.18 to get this bpf helper function. This patch adds an additional way to filter by containers, using mount namespaces. Note that this does not help with systemd services since they normally don't create a new mount namespace (unless you set some options like 'ReadOnlyPaths=', see "man 5 systemd.exec"). My goal with this patch is to filter Kubernetes pods, even on distributions with an older kernel (<4.18) or without cgroup-v2 enabled. - This is only implemented for tools that already support filtering by cgroup id (bindsnoop, capable, execsnoop, profile, tcpaccept, tcpconnect, tcptop and tcptracer). - I picked the mount namespace because the other namespaces could be disabled in Kubernetes (e.g. HostNetwork, HostPID, HostIPC). It can be tested by following the example in docs/special_filtering added in this commit, to avoid compiling locally the following command can be used ``` sudo bpftool map create /sys/fs/bpf/mnt_ns_set type hash key 8 value 4 \ entries 128 name mnt_ns_set flags 0 docker run -ti --rm --privileged \ -v /usr/src:/usr/src -v /lib/modules:/lib/modules \ -v /sys/fs/bpf:/sys/fs/bpf --pid=host kinvolk/bcc:alban-containers-filters \ /usr/share/bcc/tools/execsnoop --mntnsmap /sys/fs/bpf/mnt_ns_set ``` Co-authored-by: Alban Crequy Co-authored-by: Mauricio Vásquez --- ...ing_by_cgroups.md => special_filtering.md} | 59 +++++++++++++- man/man8/bindsnoop.8 | 7 +- man/man8/capable.8 | 7 +- man/man8/execsnoop.8 | 14 ++-- man/man8/opensnoop.8 | 7 +- man/man8/profile.8 | 4 +- man/man8/tcpaccept.8 | 7 +- man/man8/tcpconnect.8 | 8 +- man/man8/tcptop.8 | 7 +- man/man8/tcptracer.8 | 7 +- src/python/bcc/containers.py | 80 +++++++++++++++++++ tools/bindsnoop.py | 30 +++---- tools/bindsnoop_example.txt | 5 +- tools/capable.py | 24 +++--- tools/capable_example.txt | 10 ++- tools/execsnoop.py | 29 +++---- tools/execsnoop_example.txt | 6 +- tools/opensnoop.py | 31 +++---- tools/opensnoop_example.txt | 12 ++- tools/profile.py | 23 ++---- tools/profile_example.txt | 8 +- tools/tcpaccept.py | 32 +++----- tools/tcpaccept_example.txt | 5 +- tools/tcpconnect.py | 23 ++---- tools/tcpconnect_example.txt | 7 +- tools/tcptop.py | 42 +++++----- tools/tcptop_example.txt | 4 +- tools/tcptracer.py | 41 +++------- tools/tcptracer_example.txt | 2 +- 29 files changed, 322 insertions(+), 219 deletions(-) rename docs/{filtering_by_cgroups.md => special_filtering.md} (58%) create mode 100644 src/python/bcc/containers.py diff --git a/docs/filtering_by_cgroups.md b/docs/special_filtering.md similarity index 58% rename from docs/filtering_by_cgroups.md rename to docs/special_filtering.md index f2f08926d..9b15260ca 100644 --- a/docs/filtering_by_cgroups.md +++ b/docs/special_filtering.md @@ -1,4 +1,10 @@ -# Demonstrations of filtering by cgroups +# Special Filtering + +Some tools have special filtering capabitilies, the main use case is to trace +processes running in containers, but those mechanisms are generic and could +be used in other cases as well. + +## Filtering by cgroups Some tools have an option to filter by cgroup by referencing a pinned BPF hash map managed externally. @@ -66,3 +72,54 @@ map, bcc tools will display results from this shell.

So exitsnoop shows line per each thread termination if the process is multi-thread process. This is not useful when people wants to know why process terminates, not thread. So this changes exitsnoop default behavior which traces process termination instead of thread termination.

For architecture with overlapping address space, error out when bpf_probe_read_user is not available. 2. For arch with non overlapping address space, if bpf_probe_read_user is not available bpf_probe_read_user is implicitly converted to bpf_probe_read. 3.

If we were using REQ_WRITE in the BPF program, it should just work (without needing to be defined) with the appropriate #includes. 1. ```trace_start(struct pt_regs *ctx, struct request *req)```: This function will later be attached to kprobes. The arguments to kprobe functions are ```struct pt_regs *ctx```, for registers and BPF context, and then the actual arguments to the function. We'll attach this to blk_start_request(), where the first argument is ```struct request *```. 1. ```start.update(&req, &ts)```: We're using the pointer to the request struct as a key in our hash. What? This is commonplace in tracing. Pointers to structs turn out to be great keys, as they are unique: two structs can't have the same pointer address. (Just be careful about when it gets free'd and reused.) So what we're really doing is tagging the request struct, which describes the disk I/O, with our own timestamp, so that we can time it. There's two common keys used for storing timestamps: pointers to structs, and, thread IDs (for timing function entry to return). -1. ```req->__data_len```: We're dereferencing members of ```struct request```.

Namely, * syscall_helpers.{c,h}: convert system call numbers to names * errno_helpers.{c,h}: convert errno names to numbers The helpers contain pre-generated tables for x86_64 (which will be outdated at some point, so require to be updated on demand), but for other architectures require additional tools: syscall helpers require the ausyscall(1) tool, and errno helpers require errno(1) utility from the moreutils package. So, if you run on non-x86_64, then either install these tools, or use numeric values. If possible, use bpf_map_lookup_and_delete_batch function to read and reset values in the data map. This is a raceless way to obtain all values. If the function is not available, e.g., for old kernels, then fall back to the old version which can loose some syscalls (happened between reading values and resetting them).

But such optimization will place certain information, acted as the array, in the read-only section. Currently, bcc does not support read-only section, so jump table optimized code will fail during kernel verification. This is what happened to biolatpcts.py in my environment with latest llvm. -bash-4.4$ sudo ./biolatpcts.py console bpf: Failed to load program: Invalid argument unknown opcode 60 processed 0 insns (limit 1000000) max_states_per_insn 0 total_states 0 peak_states 0 mark_read 0 HINT: The 'unknown opcode' can happen if you reference a global or static variable, or data in read-only section. For example, 'char *p = "hello"' will result in p referencing a read-only section, and 'char p[] = "hello"' will have "hello" stored on the stack. This patch disabled jump table optimization on x64. The jump table optimization is guarded for llvm version 4 and above. We can disable jump table on other architectures if needed. A test case, developed based biolatpcts.py tool, is added to ensure it pass the verifier.

Along with the new --usdt-file-activation feature in bpftrace ( https://github.com/iovisor/bpftrace/pull/1317 ), bpftrace can potentially hold onto many dozens of USDT:Context instances, causing memory issues. While reducing the amount of memory USDT::Context uses is one option, we can potentially side step it by allowing the usdt semaphore count to be set independently. Before, the only way to increment the count (by 1) is to call bcc_usdt_enable*(). bcc_usdt_enable*() has checks that limit it to a single increment per context. The only way to decrement the count is by calling bcc_usdt_close() which naturally only allows for one decrement. With independent semaphore helpers, we can avoid holding onto a USDT::Context instance for the lifetime of the tracing session. We can simply: 1. create a USDT::Context 2. increment the semaphore count for the probe we care about 3. destroy the USDT::Context 4. repeat 1-3 for all probes we want to attach to 5. do our tracing 6. create a USDT::Context for the probe we care about 7. decrement the semaphore count 8. destroy the USDT::Context 9. repeat 6-8 for all the probes we're attached to This approach also has the benefit of 1 USDT::Context instance being alive at a time which can help keep memory high watermark low. [0]: Through gdb single stepping and /proc/pid/status.

For example, a decap of + * | ETH | IP | UDP | GUE | IP | TCP | into | ETH | IP | TCP | + * through **bpf_skb_adjust_room**\ () helper with passing in + * **BPF_F_ADJ_ROOM_NO_CSUM_RESET** flag would require one call + * to **bpf_csum_level**\ () with **BPF_CSUM_LEVEL_DEC** since + * the UDP header is removed. Similarly, an encap of the latter + * into the former could be accompanied by a helper call to + * **bpf_csum_level**\ () with **BPF_CSUM_LEVEL_INC** if the + * skb is still intended to be processed in higher layers of the + * stack instead of just egressing at tc. + * + * There are three supported level settings at this time: + * + * * **BPF_CSUM_LEVEL_INC**: Increases skb->csum_level for skbs + * with CHECKSUM_UNNECESSARY. + * * **BPF_CSUM_LEVEL_DEC**: Decreases skb->csum_level for skbs + * with CHECKSUM_UNNECESSARY. + * * **BPF_CSUM_LEVEL_RESET**: Resets skb->csum_level to 0 and + * sets CHECKSUM_NONE to force checksum validation by the stack. + * * **BPF_CSUM_LEVEL_QUERY**: No-op, returns the current + * skb->csum_level. + * Return + * 0 on success, or a negative error in case of failure. In the + * case of **BPF_CSUM_LEVEL_QUERY**, the current skb->csum_level + * is returned or the error code -EACCES in case the skb is not + * subject to CHECKSUM_UNNECESSARY. */ #define __BPF_FUNC_MAPPER(FN) \ FN(unspec), \ @@ -3289,7 +3384,13 @@ union bpf_attr { FN(seq_printf), \ FN(seq_write), \ FN(sk_cgroup_id), \ - FN(sk_ancestor_cgroup_id), + FN(sk_ancestor_cgroup_id), \ + FN(ringbuf_output), \ + FN(ringbuf_reserve), \ + FN(ringbuf_submit), \ + FN(ringbuf_discard), \ + FN(ringbuf_query), \ + FN(csum_level), /* integer value in 'imm' field of BPF_CALL instruction selects which helper * function eBPF program intends to call @@ -3366,6 +3467,14 @@ enum { BPF_F_CURRENT_NETNS = (-1L), };

For example, in my misjudged case: 640 bytes in 10 allocations from stack -- __kmalloc+0x178 [kernel] __kmalloc+0x178 [kernel] xhci_urb_enqueue+0x140 [kernel] usb_hcd_submit_urb+0x5e0 [kernel] This result looks like kernel doesn't free urb_priv. However, it's not true. The reason for this leak is because xhci hw irq interrupts during the BPF program. BPF program is not finished on that CPU, and xhci_irq() will call xhci_urb_free_priv() before the end. But the kernel doesn't permit this isr to go into BPF program again. Because BPF infrastructure(trace_call_bpf) denied this action. So we miss this free action and cause memory leak misjudgment. Side-effect: - Increase overhead for each memory allocation. - A higher chance to be interrupted at the allocation part causes ignore more allocations. This workaround doesn't solve all misjudgments, the improvement in BPF infrastructure is the only solution. --- man/man8/memleak.8 | 10 ++++++++-- tools/memleak.py | 18 ++++++++++++++++-- tools/memleak_example.txt | 26 ++++++++++++++++++++++++-- 3 files changed, 48 insertions(+), 6 deletions(-) diff --git a/man/man8/memleak.8 b/man/man8/memleak.8 index fa52c8cf6..2fd267643 100644 --- a/man/man8/memleak.8 +++ b/man/man8/memleak.8 @@ -3,8 +3,8 @@ memleak \- Print a summary of outstanding allocations and their call stacks to detect memory leaks.

This won't work for s390 with recent kernels since s390 has overlap user/kernel addresses and bpf_probe_read() is not available any more.

Therefore, for non-s390, the rewriter will use `bpf_probe_read()` for these implicit memory accesses.

It's supposed to load "asm/preempt.h" from "source/"(*) but accidentally loaded the one from "build/", so the error showed. (x86_64 didn't suffer this error because it didn't install the extra "asm/preempt.h" to "build/".) For the distros, e.g. SUSE/openSUSE and debian, with separate "build/" and "source/", all those "generated/" paths only exist in "build/". To avoid the potential compilation issue, this commit adjusts the include order for those with split headers to align the include order from kernel top Makefile.
