      net/lapb: tuse %*ph to dump buffers · 0d08df6c
      Andy Shevchenko authored
      Use %*ph specifier to dump small buffers in hex format instead doing this
      byte-by-byte.

      ptp: oops in ptp_ioctl() · 6756325a
      Dan Carpenter authored
      If we pass ERR_PTR(-EFAULT) to kfree() then it's going to oops.

      fou: add Kconfig options for IPv6 support · fabb13db
      Arnd Bergmann authored
      A previous patch added the fou6.ko module, but that failed to link
      in a couple of configurations:
      
      net/built-in.o: In function `ip6_tnl_encap_add_fou_ops':
      net/ipv6/fou6.c:88: undefined reference to `ip6_tnl_encap_add_ops'
      net/ipv6/fou6.c:94: undefined reference to `ip6_tnl_encap_add_ops'
      net/ipv6/fou6.c:97: undefined reference to `ip6_tnl_encap_del_ops'
      net/built-in.o: In function `ip6_tnl_encap_del_fou_ops':
      net/ipv6/fou6.c:106: undefined reference to `ip6_tnl_encap_del_ops'
      net/ipv6/fou6.c:107: undefined reference to `ip6_tnl_encap_del_ops'
      
      If CONFIG_IPV6=m, ip6_tnl_encap_add_ops/ip6_tnl_encap_del_ops
      are in a module, but fou6.c can still be built-in, and that
      obviously fails to link.
      
      Also, if CONFIG_IPV6=y, but CONFIG_IPV6_TUNNEL=m or
      CONFIG_IPV6_TUNNEL=n, the same problem happens for a different
      reason.
      
      This adds two new silent Kconfig symbols to work around both
      problems:
      
      - CONFIG_IPV6_FOU is now always set to 'm' if either CONFIG_NET_FOU=m
        or CONFIG_IPV6=m
      - CONFIG_IPV6_FOU_TUNNEL is set implicitly when IPV6_FOU is enabled
        and NET_FOU_IP_TUNNELS is also turned out, and it will ensure
        that CONFIG_IPV6_TUNNEL is also available.
      
      The options could be made user-visible as well, to give additional
      room for configuration, but it seems easier not to bother users
      with more choice here.

      ipv6: hide ip6_encap_hlen/ip6_tnl_encap definitions · 9791d8e7
      Arnd Bergmann authored
      A recent cleanup moved MAX_IPTUN_ENCAP_OPS along with some other
      definitions, but it is now invisible when CONFIG_INET is
      not defined, but still referenced from ip6_tunnel.h:
      
      In file included from net/xfrm/xfrm_input.c:17:0:
      include/net/ip6_tunnel.h:67:17: error: 'MAX_IPTUN_ENCAP_OPS' undeclared here (not in a function)
         ip6tun_encaps[MAX_IPTUN_ENCAP_OPS];
                       ^~~~~~~~~~~~~~~~~~~
      
      This hides the ip6_encap_hlen and ip6_tnl_encap functions inside
      of CONFIG_INET so we don't run into the the problem.
      
      Alternatively we could move the macro out of the #ifdef again to
      restore the previous behavior
