The second rule in prerouting chain was probably a leftover: The router listens on veth0, so not tracking connections via that interface is sufficient. Likewise, the rule in output chain can be limited to that interface as well. Signed-off-by:

Setup phase in test_port_shadow() relied upon a race-condition: Listening nc on port 1405 was started in background before attempting to create the fake conntrack entry using the same source port. If listening nc won, fake conntrack entry could not be created causing wrong behaviour. Reorder nc calls to fix this and introduce a short delay before testing the setup to wait for listening nc process startup.

Rework the reproducer for the vrf+conntrack regression reported by Eugene into a selftest and also add a test for ip masquerading that Lahav fixed recently. With net or net-next tree, the first test fails and the latter two pass. With 09e856d5 ("vrf: Reset skb conntrack connection on VRF rcv") reverted first test passes but the last two fail. A proper fix needs more work, for time being a revert seems to be the best choice, snat/masquerade did not work before the fix.

In es58x_rx_err_msg(), if can->do_set_mode() fails, the function directly returns without calling netif_rx(skb). This means that the skb previously allocated by alloc_can_err_skb() is not freed. In other terms, this is a memory leak. This patch simply removes the return statement in the error branch and let the function continue.

We recently changed bpftool's Makefile to make it install libbpf's headers locally instead of pulling them from the source directory of the library. Although bpftool needs two versions of libbpf, a "regular" one and a "bootstrap" version, we would only install headers for the regular libbpf build. Given that this build always occurs before the bootstrap build when building bpftool, this is enough to ensure that the bootstrap bpftool will have access to the headers exported through the regular libbpf build. However, this did not account for the case when we only want the bootstrap version of bpftool, through the "bootstrap" target. For example, perf needs the bootstrap version only, to generate BPF skeletons. In that case, when are the headers installed? For some time, the issue has been masked, because we had a step (the installation of headers internal to libbpf) which would depend on the regular build of libbpf and hence trigger the export of the headers, just for the sake of creating a directory. But this changed with commit 8b6c4624 ("bpftool: Remove Makefile dep. on $(LIBBPF) for $(LIBBPF_INTERNAL_HDRS)"), where we cleaned up that stage and removed the dependency on the regular libbpf build. As a result, when we only want the bootstrap bpftool version, the regular libbpf is no longer built. The bootstrap libbpf version is built, but headers are not exported, and the bootstrap bpftool build fails because of the missing headers. To fix this, we also install the library headers for the bootstrap version of libbpf, to use them for the bootstrap bpftool and for generating the skeletons. Fixes: f012ade1 ("bpftool: Install libbpf headers instead of including the dir") Reported-by:

udp_mem is a vector of 3 INTEGERs, which is used to limit the number of pages allowed for queueing by all UDP sockets. However, sk_has_memory_pressure() in __sk_mem_raise_allocated() always return false for udp, as memory pressure is not supported by udp, which means that __sk_mem_raise_allocated() will fail once pages allocated for udp socket exceeds udp_mem[0]. Therefor, udp_mem[0] is the only one that limit the number of pages. However, the document of udp_mem just express that udp_mem[2] is the limitation. So, just fix it. Signed-off-by:
