2020-08-19libbpf: Centralize poisoning and poison reallocarray()Andrii Nakryiko12-33/+13
Most of libbpf source files already include libbpf_internal.h, so it's a good place to centralize identifier poisoning. So move kernel integer type poisoning there. And also add reallocarray to a poison list to prevent accidental use of it. libbpf_reallocarray() should be used universally instead.

2020-08-19tools/bpftool: Remove libbpf_internal.h usage in bpftoolAndrii Nakryiko4-150/+288
Most netlink-related functions were unique to bpftool usage, so I moved them into net.c. Few functions are still used by both bpftool and libbpf itself internally, so I've copy-pasted them (libbpf_nl_get_link, libbpf_netlink_open). It's a bit of duplication of code, but better separation of libbpf as a library with public API and bpftool, relying on unexposed functions in libbpf.

2020-08-19libbpf: Remove any use of reallocarray() in libbpfAndrii Nakryiko6-29/+45
Re-implement glibc's reallocarray() for libbpf internal-only use. reallocarray(), unfortunately, is not available in all versions of glibc, so requires extra feature detection and using reallocarray() stub from <tools/libc_compat.h> and COMPAT_NEED_REALLOCARRAY. All this complicates build of libbpf unnecessarily and is just a maintenance burden. Instead, it's trivial to implement libbpf-specific internal version and use it throughout libbpf. Which is what this patch does, along with converting some realloc() uses that should really have been reallocarray() in the first place.

2020-08-19libbpf: Improve relocation ambiguity detectionAndrii Nakryiko1-46/+124
Split the instruction patching logic into relocation value calculation and application of relocation to instruction. Using this, evaluate relocation against each matching candidate and validate that all candidates agree on relocated value. If not, report ambiguity and fail load. This logic is necessary to avoid dangerous (however unlikely) accidental match against two incompatible candidate types. Without this change, libbpf will pick a random type as *the* candidate and apply potentially invalid relocation.

2020-08-19libbpf: Make kernel feature probing lazyAndrii Nakryiko1-64/+86
Turn libbpf's kernel feature probing into lazily-performed checks. This allows to skip performing unnecessary feature checks, if a given BPF application doesn't rely on a particular kernel feature. As we grow number of feature probes, libbpf might perform less unnecessary syscalls and scale better with number of feature probes long-term. By decoupling feature checks from bpf_object, it's also possible to perform feature probing from libbpf static helpers and low-level APIs, if necessary.

2020-08-15all arch: remove system call sys_sysctlXiaoming Ni3-3/+3
Since commit 61a47c1ad3a4dc ("sysctl: Remove the sysctl system call"), sys_sysctl is actually unavailable: any input can only return an error. We have been warning about people using the sysctl system call for years and believe there are no more users. Even if there are users of this interface if they have not complained or fixed their code by now they probably are not going to, so there is no point in warning them any longer. So completely remove sys_sysctl on all architectures.

2020-08-14perf ftrace: Select function/function_graph tracer automaticallyChangbin Du3-23/+48
The '-g/-G' options have already implied function_graph tracer should be used instead of function tracer. So we don't need extra option '--tracer' in this case. This patch changes the behavior as below: - If '-g' or '-G' option is on, then function_graph tracer is used. - If '-T' or '-N' option is on, then function tracer is used. - The function_graph has priority over function tracer. - The option '--tracer' only take effect if neither -g/-G nor -T/-N is specified. Here are some examples. This will start tracing all functions using default tracer: $ sudo perf ftrace This will trace all functions using function graph tracer: $ sudo perf ftrace -G '*' This will trace function vfs_read using function graph tracer: $ sudo perf ftrace -G vfs_read This will trace function vfs_read using function tracer: $ sudo perf ftrace -T vfs_read Committer notes: Using '-h -G' will tell what that option is about, so to further clarify the above examples: # perf ftrace -h -G -G, --graph-funcs <func> Set graph filter on given functions # perf ftrace -h -g -g, --nograph-funcs <func> Set nograph filter on given functions # perf ftrace -h -T -T, --trace-funcs <func> trace given functions only # perf ftrace -h -N -N, --notrace-funcs <func> do not trace given functions # Signed-off-by: Changbin Du <changbin.du@gmail.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Acked-by: Namhyung Kim <namhyung@kernel.org> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Steven Rostedt (VMware) <rostedt@goodmis.org> Link: http://lore.kernel.org/lkml/20200808023141.14227-2-changbin.du@gmail.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
