net: ipv6_stub: use ip6_dst_lookup_flow instead of ip6_dst_lookup

2019-12-04T20:27:13Z

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.

ipv6: include for missing declarations

2019-10-22T22:17:03Z

Include for the missing declarations of various functions. Fixes the following sparse warnings: net/ipv6/addrconf_core.c:94:5: warning: symbol 'register_inet6addr_notifier' was not declared. Should it be static? net/ipv6/addrconf_core.c:100:5: warning: symbol 'unregister_inet6addr_notifier' was not declared.

ipv6: Add delete route hook to stubs

2019-05-23T00:48:43Z

Add ip6_del_rt to the IPv6 stub. The hook is needed by the nexthop code to remove entries linked to a nexthop that is getting deleted. Signed-off-by: David Ahern Signed-off-by: David S. Miller

treewide: Add SPDX license identifier for missed files

2019-05-21T08:50:45Z

Add SPDX license identifiers to all files which: - Have no license information of any form - Have EXPORT_.*_SYMBOL_GPL inside which was used in the initial scan/conversion to ignore the file These files fall under the project license, GPL v2 only. The resulting SPDX license identifier is: GPL-2.0-only Signed-off-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman

ipv6: Pass fib6_result to fib lookups

2019-04-18T06:10:47Z

Change fib6_lookup and fib6_table_lookup to take a fib6_result and set f6i and nh rather than returning a fib6_info. For now both always return 0. A later patch set can make these more like the IPv4 counterparts and return EINVAL, EACCESS, etc based on fib6_type. Signed-off-by: David Ahern Signed-off-by: David S. Miller

ipv6: Pass fib6_result to ip6_mtu_from_fib6 and fib6_mtu

2019-04-18T06:10:46Z

Change ip6_mtu_from_fib6 and fib6_mtu to take a fib6_result over a fib6_info. Update both to use the fib6_nh from fib6_result. Since the signature of ip6_mtu_from_fib6 is already changing, add const to daddr and saddr. Signed-off-by: David Ahern Signed-off-by: David S. Miller

ipv6: Rename fib6_multipath_select and pass fib6_result

2019-04-18T06:08:51Z

Add 'struct fib6_result' to hold the fib entry and fib6_nh from a fib lookup as separate entries, similar to what IPv4 now has with fib_result. Rename fib6_multipath_select to fib6_select_path, pass fib6_result to it, and set f6i and nh in the result once a path selection is done. Call fib6_select_path unconditionally for path selection which means moving the sibling and oif check to fib6_select_path. To handle the two different call paths (2 only call multipath_select if flowi6_oif == 0 and the other always calls it), add a new have_oif_match that controls the sibling walk if relevant. Update callers of fib6_multipath_select accordingly and have them use the fib6_info and fib6_nh from the result. This is needed for multipath nexthop objects where a single f6i can point to multiple fib6_nh (similar to IPv4). Signed-off-by: David Ahern Signed-off-by: David S. Miller

ipv6: Add fib6_nh_init and release to stubs

2019-04-08T22:22:40Z

Add fib6_nh_init and fib6_nh_release to ipv6_stubs. If fib6_nh_init fails, callers should not invoke fib6_nh_release, so there is no reason to have a dummy stub for the IPv6 is not enabled case. Signed-off-by: David Ahern Reviewed-by: Ido Schimmel Signed-off-by: David S. Miller

ipv6: Move ipv6 stubs to a separate header file

2019-03-29T17:53:45Z

The number of stubs is growing and has nothing to do with addrconf. Move the definition of the stubs to a separate header file and update users. In the move, drop the vxlan specific comment before ipv6_stub. Code move only; no functional change intended. Signed-off-by: David Ahern Signed-off-by: David S. Miller

ipv6_stub: add ipv6_route_input stub/proxy.
