* bcc: De-vendor libbpfDaniel Thompson2022-05-271-0/+2
| | | | | | | | | | | | | | | | | | | | | | | Currently bcc builds against a vendored copy of libbpf. This causes problems for bpftrace which is built against bcc and the system libbpf. The resulting version skew between the vendored and system versions of libbpf resulting in a SEGV whenever bpftrace is used. Although --help and -l (list probe points) work OK that is because they do not actually use BPF! Anything that does use BPF will crash immediately, including bpftrace --info and simple one-liners such as: ~# bpftrace -e 't:raw_syscalls:sys_exit { printf("%s", comm); }' Attaching 1 probe... Segmentation fault Note that this issue is very closely related to similar problems compiling bpftrace against mixed headers from the two libbpf versions.

* bcc: Fixes to allow libbpf to be de-vendoredDaniel Thompson2022-05-272-0/+125
| | | | | | | | | | | | De-vendoring libbpf resolves a SEGV everytime we run bpftrace. Unfortunately it is not currently possible to de-vendor libbpf because bcc does not build. Fix this with brute force and ignorance... and in a seperate patch so this can be treated as an explanation of the problem and ripped out in favour of the right fix.

| | | | | | | | | | | | In order to use latest clang, latest bcc sources are needed, this also means that we need to use vendored libbpf as thats the newest one needed and avoids dependencies on kernel bpf headers which maybe old and out of sync examples use error.h header which is not available on musl therefore disable examples when building on musl Signed-off-by: Khem Raj <raj.khem@gmail.com>
