netfilter: ebtables: Fixes dropping of small packets in bridge nat

2020-10-20T11:54:53Z

Fixes an error causing small packets to get dropped. skb_ensure_writable expects the second parameter to be a length in the ethernet payload.=20 If we want to write the ethernet header (src, dst), we should pass 0. Otherwise, packets with small payloads (< ETH_ALEN) will get dropped.

Rejecting non-native endian BTF overlapped with the addition of support for it. The rest were more simple overlapping changes, except the renesas ravb binding update, which had to follow a file move as well as a YAML conversion. Signed-off-by: David S. Miller

net: core: introduce struct netdev_nested_priv for nested interface infrastructure

2020-09-28T22:00:15Z

Functions related to nested interface infrastructure such as netdev_walk_all_{ upper | lower }_dev() pass both private functions and "data" pointer to handle their own things. At this point, the data pointer type is void *. In order to make it easier to expand common variables and functions, this new netdev_nested_priv structure is added. In the following patch, a new member variable will be added into this struct to fix the lockdep issue. Signed-off-by: Taehee Yoo Signed-off-by: David S. Miller

net: bridge: fdb: don't flush ext_learn entries

2020-09-28T19:47:43Z

When a user-space software manages fdb entries externally it should set the ext_learn flag which marks the fdb entry as externally managed and avoids expiring it (they're treated as static fdbs). Unfortunately on events where fdb entries are flushed (STP down, netlink fdb flush etc) these fdbs are also deleted automatically by the bridge. That in turn causes trouble for the managing user-space software (e.g. in MLAG setups we lose remote fdb entries on port flaps). These entries are completely externally managed so we should avoid automatically deleting them, the only exception are offloaded entries (i.e. BR_FDB_ADDED_BY_EXT_LEARN + BR_FDB_OFFLOADED). They are flushed as before. Fixes: eb100e0e24a2 ("net: bridge: allow to add externally learned entries from user-space") Signed-off-by: Nikolay Aleksandrov Signed-off-by: David S. Miller

net: bridge: mcast: remove only S,G port groups from sg_port hash

2020-09-25T23:50:19Z

We should remove a group from the sg_port hash only if it's an S,G entry. This makes it correct and more symmetric with group add. Also since *,G groups are not added to that hash we can hide a bug.

net: bridge: mcast: when forwarding handle filter mode and blocked flag

We need to avoid forwarding to ports in MCAST_INCLUDE filter mode when the mdst entry is a *,G or when the port has the blocked flag. Signed-off-by: Nikolay Aleksandrov Signed-off-by: David S. Miller

net: bridge: mcast: handle host state

2020-09-23T20:24:34Z

Since host joins are considered as EXCLUDE {} joins we need to reflect that in all of *,G ports' S,G entries. Since the S,Gs can have host_joined == true only set automatically we can safely set it to false when removing all automatically added entries upon S,G delete.
