google.golang.org/protobuf/cmd/protoc-gen-go@v1.34.2 generates
protobuffers incompatible with go1.17, it fails with the error:
"ui/protocol/ui.pb.go:2716:47: predeclared any requires go1.18 or later
(-lang was set to go1.17; check go.mod)"
Notes:
- consider using go1.18 as min required version if there's no problem
compiling the daemon on Debian <= 13 and other distros.
- github.com/golang/protobuf is deprecated and we should get rid of
it.
- Don't rename libbpf's bpf_map_def struct, and distribute the needed bpf
headers.
The bpf_map_def struct has been deprecated for quite some time now,
and it was been removed on >= 6.2 anyway.
We still need it, because we use gobpf.
- Improved compilation behaviour:
- We don't require the kernel sources anymore. We can just use the
kernel headers from the distribution.
- There's no need to copy the sources to the kernel tree, the modules
can be compiled from the ebpf_prog/ dir.
- Compiling against kernels 6.x seems to solve the problem we had with
VPNs, where connections were not intercepted with modules compiled
against 5.8, on kernels >= 5.19.
The modules has been tested on kernels 4.17, 5.4, 5.10, 5.15, 6.1 and
6.2 (kernel connections included).
Closes: #939
Build eBPF modules whenever a change to the modules is pushed.
It'll fail if there're some warnings.
The action compiles *and publishes* the modules for several branches and
kernels.
Hopefully this will help to automate this process and be more transparent.
It'll also help on issues like this one: #454
rename, remove unused targets
trigger targets only when relevant files actually are changed
git:
do not track files which are generated during make
github actions fix to not rely on a pre-built ui.pb.go
