dn_route: set rt neigh to blackhole_netdev instead of loopback_dev in ifdown

2022-05-18T01:03:23Z

Like other places in ipv4/6 dst ifdown, change to use blackhole_netdev instead of pernet loopback_dev in dn dst ifdown. Signed-off-by: Xin Long Link: https://lore.kernel.org/r/0cdf10e5a4af509024f08644919121fb71645bc2.1652751029.git.lucien.xin@gmail.com Signed-off-by: Jakub Kicinski

decnet: Use container_of() for struct dn_neigh casts

2022-05-10T10:21:51Z

Clang's structure layout randomization feature gets upset when it sees struct neighbor (which is randomized) cast to struct dn_neigh: net/decnet/dn_route.c:1123:15: error: casting from randomized structure pointer type 'struct neighbour *' to 'struct dn_neigh *' gateway = ((struct dn_neigh *)neigh)->addr; ^ Update all the open-coded casts to use container_of() to do the conversion instead of depending on strict member ordering.

net: Don't include filter.h from net/sock.h

2021-12-29T16:48:14Z

sock.h is pretty heavily used (5k objects rebuilt on x86 after it's touched). We can drop the include of filter.h from it and add a forward declaration of struct sk_filter instead. This decreases the number of rebuilt objects when bpf.h is touched from ~5k to ~1k. There's a lot of missing includes this was masking. Primarily in networking tho, this time.

net: decnet: Fix refcount warning for new dn_fib_info

2021-08-03T21:23:22Z

fib_treeref needs to be set after kzalloc. The old code had a ++ which led to the confusion when the int was replaced by a refcount_t.
