There is a structural problem in switchdev, where the flag bits in struct switchdev_notifier_fdb_info (added_by_user, is_local etc) only represent a simplified / denatured view of what's in struct net_bridge_fdb_entry :: flags (BR_FDB_ADDED_BY_USER, BR_FDB_LOCAL etc). Each time we want to pass more information about struct net_bridge_fdb_entry :: flags to struct switchdev_notifier_fdb_info

A malicious actor behind one bridge port may spam the kernel with packets with a random source MAC address, each of which will create an FDB entry, each of which is a dynamic allocation in the kernel. There are roughly 2^48 different MAC addresses, further limited by the rhashtable they are stored in to 2^31. Each entry is of the type struct net_bridge_fdb_entry, which is currently 128 bytes big.

This allows the called fdb_create to detect that the entry was added by the user early in the process. This is in preparation to adding limits in fdb_create that should not apply to user created fdb entries.

Hello, Sometimes I have to create and use Navision Databases on samba shares - this works with samba 2.0.x but does not with samba 2.2.x (tried 2.2.3a and 2.2.4). The following tests were done with a acl enabeled samba and an acl aware kernel/filesystem, but I also have done these tests with acl not compiled into samba on an host without acl in the kernel - same result, does not work, same

Test FDB ageing of user entry created by bridge fdb replace ADDR dev <DEV> master dynamic Use LOW_AGEING_TIME variable in forwarding.config to set a low ageing time. Beware, DSA might not accept the ageing time you want. Check the age_time_coeff value for your driver. Signed-off-by: Hans J.
