We use xdp-loader to load dnsdist_xdp.bpf.o for dnsdist running
AF_XDP:
xdp-loader load green0 -P 90 -p /sys/fs/bpf/dnsdist -n xdp_dns_filter /usr/lib/bpf/dnsdist_xdp.bpf.o
so the xsk v4/v6 destination map would be:
/sys/fs/bpf/dnsdist/xskDestinationsV4
/sys/fs/bpf/dnsdist/xskDestinationsV6
but dnsdist-xsk.cc has:
static std::string getDestinationMap(bool isV6)
{
return !isV6 ? "/sys/fs/bpf/dnsdist/xsk-destinations-v4" : "/sys/fs/bpf/dnsdist/xsk-destinations-v6";
}
we can't use xsk-destinations-v4/v6 in dnsdist_xdp.bpf.o because bpf map
could not use '-' in map definition, '-' would result in compiling
error.
so we patch dnsdist-xsk.cc to use xskDestinationsV4/V6 that matches the
map name in dnsdist_xdp.bpf.o

We are going to add pwru for packet drop related
trouble shooting, pwru by default requires kernel
with kprobe multi attachment, enable kernel config
for that.

Similar to xdp-tools to add ebpf network program.
we can use libbpf-bootstrap as facility to add ebpf
tracing program.

bpftrace depends on libbcc, so add bcc in build.
bcc build depends on zip, but loongfire does not
have zip
workaround:
copy loongson host Fedora zip command to chroot build
cp /usr/bin/zip to build_loongarch64/usr/bin
Fedora zip depends on libbz2.so.1, libbz2 is from bzip2
addon that loongfire already has, so make symbolic link
cd build_loongarch64/lib64; ln -s libbz2.so.1.0.8 libbz2.so.1
we should build zip addon for loongfire but zip has build error
need to resolve zip build error as long term solution

rebase xdp-tools from upstream xdp-tools 1.5.4. there is
Makefile conflict when rebase because 1.5.4 added xdp-forward.
manually resolve the rebase conflict by put loongfire xdp program
at the end:
for example instruction from deepseek:
Open the Makefile in a text editor and locate the conflict:
makefile
ifneq ($(BPFTOOL),)
<<<<<<< HEAD
UTILS += xdp-bench xdp-forward xdp-monitor xdp-trafficgen
=======
UTILS += xdp-bench xdp-monitor xdp-trafficgen xdp-synproxy
>>>>>>> d8ebb16 (Add xdp-synproxy)
endif
Understand the conflict:
The HEAD (upstream/main) version includes xdp-forward.
Your commit (d8ebb16) adds xdp-synproxy but removes xdp-forward.
Resolve the conflict by including both changes:
Keep xdp-forward from HEAD.
Add xdp-synproxy from your commit.
The merged line should look like this:
makefile
UTILS += xdp-bench xdp-forward xdp-monitor xdp-trafficgen xdp-synproxy
Remove the conflict markers (<<<<<<<, =======, >>>>>>>).
edit result:
ifneq ($(BPFTOOL),)
UTILS += xdp-bench xdp-forward xdp-monitor xdp-trafficgen xdp-synproxy
endif
Save the file after making these changes.
Stage the resolved Makefile and continue the rebase:
git add Makefile
git rebase --continue
repeat editing Makefile and git rebase --continue for below program
xdp-dnsrrl
xdp-udp
xdp-dns
xdp-sni
xdp-geoip
xdp-udpddos
xdp-tailcall
xdp-synproxy-tailcall
xdp-ddos
