Since Buildroot commit 25cb3813e7 which
bumped LLVM from 21.x to 22.x, the build of bpftrace is broken as
bpftrace 0.24.2 only supports LLVM up to 21.
We tried backporting the bpftrace patch that allows using LLVM up to
version 22 but the patch didn't apply cleanly but more importantly it
wasn't clear if this patch was sufficient. Therefore, we opt for
bumping bpftrace entirely to fix the issue.
Packaging changes:
- The new version of bpftrace no longer needs host-bison/host-flex,
because bpftrace is now using a handwritten parser.
- Pass -DUSE_SYSTEM_LIBBPF:BOOL=ON to ensure the system libbpf version
is used, and not the bundled version
- Now depends on kernel headers >= 5.10 because it needs CAP_BPF and
CAP_PERFMON

|
bpftrace is a high-level tracing language for Linux enhanced
|
|
Berkeley Packet Filter (eBPF) available in recent Linux
|
|
kernels (4.x).
|
|
|
|
bpftrace uses LLVM as a backend to compile scripts to
|
|
BPF-bytecode and makes use of BCC for interacting with the
|
|
Linux BPF system, as well as existing Linux tracing
|
|
capabilities: kernel dynamic tracing (kprobes), user-level
|
|
dynamic tracing (uprobes), and tracepoints. The bpftrace
|
|
language is inspired by awk and C, and predecessor tracers
|
|
such as DTrace and SystemTap.
|
|
|
|
It's highly recommended to NOT strip bpftrace binary.
|
|
To do so, add "bpftrace" to BR2_STRIP_EXCLUDE_FILES.
