Package: bpfcc Version: 0.17.0-9 Severity: wishlist Hi!
(Cc-ing the kernel team, since it might be relevant for coordination or packaging efforts, please feel free to reassign to src:linux if that should be more appropriate) With the ongoing efforts around BTF and CO-RE (see http://www.brendangregg.com/blog/2020-11-04/bpf-co-re-btf-libbpf.html), it would be nice to have a decent and working toolchain for it with our upcoming bullseye release. Given that CONFIG_DEBUG_INFO_BTF support is in the works (see #973870), it would be nice, if we could provide bcc's libbpf-tools through a separate package. Looking at e.g. libbpf-tools's compiled biolatency binary, it only depends on libc6, libelf1 + zlib1g and it's less than 250kb (stripped) total size: | % ldd ./biolatency | linux-vdso.so.1 (0x00007ffcb01ef000) | libelf.so.1 => /lib/x86_64-linux-gnu/libelf.so.1 (0x00007f348b386000) | libz.so.1 => /lib/x86_64-linux-gnu/libz.so.1 (0x00007f348b369000) | libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f348b1a4000) | /lib64/ld-linux-x86-64.so.2 (0x00007f348b3e6000) | % ls -lah ./biolatency | -rwxr-xr-x 1 mika mika 239K Dec 30 13:47 ./biolatency Same for all the other tools which are currently shipped via libbpf-tools (see https://github.com/iovisor/bcc/tree/master/libbpf-tools), all being below 250KB and depending only on libc6, libelf1 + zlib1g. Whereas bpfcc-tools pulls in over 200MB of of additional disk space, bpftrace still also adds ~190MB of disk space - mainly due to their dependency on libllvm11. So IMO it would be great, if it's possible to ship libbpf-tools on Debian/bullseye systems without giving it much thoughts due to dependencies and disk space requirements. regards -mika-
