[PATCH net-next 4/4] netlink: implement nla_get_in_addr and nla_get_in6_addr
From: Jiri Benc <hidden>
Date: 2015-03-29 15:00:31
Subsystem:
802.11 (including cfg80211/nl80211), networking drivers, networking [general], networking [ipsec], networking [ipv4/ipv6], networking [tcp], openvswitch, the rest · Maintainers:
Johannes Berg, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Steffen Klassert, Herbert Xu, David Ahern, Ido Schimmel, Neal Cardwell, Aaron Conole, Eelco Chaudron, Ilya Maximets, Linus Torvalds
Those are counterparts to nla_put_in_addr and nla_put_in6_addr. Signed-off-by: Jiri Benc <redacted> --- Note that nla_get_in6_addr returns the struct in6_addr rather than a pointer to it. This may be frown upon by some; if desired, I'll rework the function to accept target pointer as a parameter. --- drivers/net/vxlan.c | 16 +++++++--------- include/net/netlink.h | 21 +++++++++++++++++++++ net/ipv4/devinet.c | 10 +++++----- net/ipv4/fib_rules.c | 8 ++++---- net/ipv4/fib_semantics.c | 4 ++-- net/ipv4/ip_gre.c | 4 ++-- net/ipv4/ip_vti.c | 4 ++-- net/ipv4/ipip.c | 4 ++-- net/ipv4/netfilter/nf_conntrack_l3proto_ipv4.c | 4 ++-- net/ipv4/route.c | 4 ++-- net/ipv4/tcp_metrics.c | 4 ++-- net/ipv6/fib6_rules.c | 6 ++---- net/ipv6/ip6_gre.c | 6 +++--- net/ipv6/ip6_tunnel.c | 6 ++---- net/ipv6/ip6_vti.c | 6 ++---- net/ipv6/netfilter/nf_conntrack_l3proto_ipv6.c | 6 ++---- net/ipv6/route.c | 6 +++--- net/ipv6/sit.c | 3 +-- net/l2tp/l2tp_netlink.c | 4 ++-- net/openvswitch/flow_netlink.c | 4 ++-- net/wireless/nl80211.c | 4 ++-- 21 files changed, 72 insertions(+), 62 deletions(-)
