vxlan: use the correct nlattr array in NL_SET_ERR_MSG_ATTR

2020-04-29T14:34:41+00:00

[ Upstream commit cc8e7c69db4dcc565ed3020f97ddd6debab6cbe8 ] IFLA_VXLAN_* attributes are in the data array, which is correctly used when fetching the value, but not when setting the extended ack. Because IFLA_VXLAN_MAX < IFLA_MAX, we avoid out of bounds array accesses, but we don't provide a pointer to the invalid attribute to userspace.

vxlan: check return value of gro_cells_init()

2020-03-18T23:43:12+00:00

gro_cells_init() returns error if memory allocation is failed. But the vxlan module doesn't check the return value of gro_cells_init(). Fixes: 58ce31cca1ff ("vxlan: GRO support at tunnel layer")` Signed-off-by: Taehee Yoo Signed-off-by: David S. Miller

vxlan: fix tos value before xmit

2020-01-03T00:35:48+00:00

Before ip_tunnel_ecn_encap() and udp_tunnel_xmit_skb() we should filter tos value by RT_TOS() instead of using config tos directly. vxlan_get_route() would filter the tos to fl4.flowi4_tos but we didn't return it back, as geneve_get_v4_rt() did. So we have to use RT_TOS() directly in function ip_tunnel_ecn_encap().

treewide: Use sizeof_field() macro

2019-12-09T18:36:44+00:00

Replace all the occurrences of FIELD_SIZEOF() with sizeof_field() except at places where these are defined. Later patches will remove the unused definition of FIELD_SIZEOF().

net: ipv6_stub: use ip6_dst_lookup_flow instead of ip6_dst_lookup

2019-12-04T20:27:13+00:00

ipv6_stub uses the ip6_dst_lookup function to allow other modules to perform IPv6 lookups. However, this function skips the XFRM layer entirely. All users of ipv6_stub->ip6_dst_lookup use ip_route_output_flow (via the ip_route_output_key and ip_route_output helpers) for their IPv4 lookups, which calls xfrm_lookup_route(). This patch fixes this inconsistent behavior by switching the stub to ip6_dst_lookup_flow, which also calls xfrm_lookup_route(). This requires some changes in all the callers, as these two functions take different arguments and have different return types.
