[PATCHv4 RESEND net-next 0/2] selftests: wireguards: use nftables for testing

[Hangbin Liu]

This patch set convert iptables to nftables for wireguard testing, as
iptables is deparated and nftables is the default framework of most releases.

v3: drop iptables directly (Jason A. Donenfeld)
    Also convert to using nft for qemu testing (Jason A. Donenfeld)
v2: use one nft table for testing (Phil Sutter)

[PATCHv4 RESEND net-next 2/2] selftests: wireguard: update to using nft for qemu test

[Hangbin Liu]

Since we will replace iptables with nft for wireguard netns testing,
let's also convert the qemu test to use nft at the same time.

I saw the patch status[1] is still "Awaiting Upstream".
Is there anything I need to do?

Can't these be statically linked into the nft binary?

I was able to have nft linked statically against built libmnl and
libnftnl by passing '--disable-shared --enable-static' to configure
calls of all three build systems. With --enable-shared in library
configure calls, nftables build preferred to link against the DSOs and I
did not find a way to change this.

Cheers, Phil

The patch is using
"./configure --prefix=/ $(CROSS_COMPILE_FLAG) --enable-static \
--disable-shared --disable-debug --disable-man-doc --with-mini-gmp --without-cli"
to build nft.

I don't know why it's not linked static.

Thanks
