      net: vrf: Make add_fib_rules per network namespace flag · 097d3c95
      David Ahern authored
      Commit 1aa6c4f6 ("net: vrf: Add l3mdev rules on first device create")
      adds the l3mdev FIB rule the first time a VRF device is created. However,
      it only creates the rule once and only in the namespace the first device
      is created - which may not be init_net. Fix by using the net_generic
      capability to make the add_fib_rules flag per network namespace.

      bpf, tests: fix endianness selection · 78a5a93c
      Daniel Borkmann authored
      I noticed that test_l4lb was failing in selftests:
      
        # ./test_progs
        test_pkt_access:PASS:ipv4 77 nsec
        test_pkt_access:PASS:ipv6 44 nsec
        test_xdp:PASS:ipv4 2933 nsec
        test_xdp:PASS:ipv6 1500 nsec
        test_l4lb:PASS:ipv4 377 nsec
        test_l4lb:PASS:ipv6 544 nsec
        test_l4lb:FAIL:stats 6297600000 200000
        test_tcp_estats:PASS: 0 nsec
        Summary: 7 PASSED, 1 FAILED
      
      Tracking down the issue actually revealed that endianness selection
      in bpf_endian.h is broken when compiled with clang with bpf target.
      test_pkt_access.c, test_l4lb.c is compiled with __BYTE_ORDER as
      __BIG_ENDIAN, test_xdp.c as __LITTLE_ENDIAN! test_l4lb noticeably
      fails, because the test accounts bytes via bpf_ntohs(ip6h->payload_len)
      and bpf_ntohs(iph->tot_len), and compares them against a defined
      value and given a wrong endianness, the test outcome is different,
      of course.
      
      Turns out that there are actually two bugs: i) when we do __BYTE_ORDER
      comparison with __LITTLE_ENDIAN/__BIG_ENDIAN, then depending on the
      include order we see different outcomes. Reason is that __BYTE_ORDER
      is undefined due to missing endian.h include. Before we include the
      asm/byteorder.h (e.g. through linux/in.h), then __BYTE_ORDER equals
      __LITTLE_ENDIAN since both are undefined, after the include which
      correctly pulls in linux/byteorder/little_endian.h, __LITTLE_ENDIAN
      is defined, but given __BYTE_ORDER is still undefined, we match on
      __BYTE_ORDER equals to __BIG_ENDIAN since __BIG_ENDIAN is also
      undefined at that point, sigh. ii) But even that would be wrong,
      since when compiling the test cases with clang, one can select between
      bpfeb and bpfel targets for cross compilation. Hence, we can also not
      rely on what the system's endian.h provides, but we need to look at
      the compiler's defined endianness. The compiler defines __BYTE_ORDER__,
      and we can match __ORDER_LITTLE_ENDIAN__ and __ORDER_BIG_ENDIAN__,
      which also reflects targets bpf (native), bpfel, bpfeb correctly,
      thus really only rely on that. After patch:
      
        # ./test_progs
        test_pkt_access:PASS:ipv4 74 nsec
        test_pkt_access:PASS:ipv6 42 nsec
        test_xdp:PASS:ipv4 2340 nsec
        test_xdp:PASS:ipv6 1461 nsec
        test_l4lb:PASS:ipv4 400 nsec
        test_l4lb:PASS:ipv6 530 nsec
        test_tcp_estats:PASS: 0 nsec
        Summary: 7 PASSED, 0 FAILED
