net: bridge: move br_fdb_replay inside br_switchdev.c

2021-10-27T13:54:02Z

br_fdb_replay is only called from switchdev code paths, so it makes sense to be disabled if switchdev is not enabled in the first place. As opposed to br_mdb_replay and br_vlan_replay which might be turned off depending on bridge support for multicast and VLANs, FDB support is always on. So moving br_mdb_replay and br_vlan_replay inside br_switchdev.c would mean adding some #ifdef's in br_switchdev.c, so we keep those where they are. The reason for the movement is that in future changes there will be some code reuse between br_switchdev_fdb_notify and br_fdb_replay.

net: bridge: reduce indentation level in fdb_create

2021-10-27T13:54:02Z

We can express the same logic without an "if" condition as big as the function, just return early if the kmem_cache_alloc() call fails. Signed-off-by: Vladimir Oltean Reviewed-by: Ido Schimmel Acked-by: Nikolay Aleksandrov Signed-off-by: David S. Miller

net: bridge: rename br_fdb_insert to br_fdb_add_local

2021-10-27T13:54:02Z

br_fdb_insert() is a wrapper over fdb_insert() that also takes the bridge hash_lock. With fdb_insert() being renamed to fdb_add_local(), rename br_fdb_insert() to br_fdb_add_local().

net: bridge: rename fdb_insert to fdb_add_local

2021-10-27T13:54:02Z

fdb_insert() is not a descriptive name for this function, and also easy to confuse with __br_fdb_add(), fdb_add_entry(), br_fdb_update(). Even more confusingly, it is not even related in any way with those functions, neither one calls the other. Since fdb_insert() basically deals with the creation of a BR_FDB_LOCAL entry and is called only from functions where that is the intention: - br_fdb_changeaddr - br_fdb_change_mac_address - br_fdb_insert then rename it to fdb_add_local(), because its removal counterpart is called fdb_delete_local().

net: bridge: remove fdb_insert forward declaration

2021-10-27T13:54:02Z

fdb_insert() has a forward declaration because its first caller, br_fdb_changeaddr(), is declared before fdb_create(), a function which fdb_insert() needs. This patch moves the 2 functions above br_fdb_changeaddr() and deletes the forward declaration for fdb_insert().

net: bridge: remove fdb_notify forward declaration

2021-10-27T13:54:02Z

fdb_notify() has a forward declaration because its first caller, fdb_delete(), is declared before 3 functions that fdb_notify() needs: fdb_to_nud(), fdb_fill_info() and fdb_nlmsg_size(). This patch moves the aforementioned 4 functions above fdb_delete() and deletes the forward declaration.

net: bridge: fix flags interpretation for extern learn fdb entries

2021-08-10T18:29:39Z

Ignore fdb flags when adding port extern learn entries and always set BR_FDB_LOCAL flag when adding bridge extern learn entries. This is closest to the behaviour we had before and avoids breaking any use cases which were allowed. This patch fixes iproute2 calls which assume NUD_PERMANENT and were allowed before, example: $ bridge fdb add 00:11:22:33:44:55 dev swp1 extern_learn Extern learn entries are allowed to roam, but do not expire, so static or dynamic flags make no sense for them. Also add a comment for future reference.
