2022-12-12bridge: mcast: Allow user space to add (*, G) with a source list and filter modeIdo Schimmel2-0/+150
Add new netlink attributes to the RTM_NEWMDB request that allow user space to add (*, G) with a source list and filter mode. The RTM_NEWMDB message can already dump such entries (created by the kernel) so there is no need to add dump support. However, the message contains a different set of attributes depending if it is a request or a response. The naming and structure of the new attributes try to follow the existing ones used in the response. Request: [ struct nlmsghdr ] [ struct br_port_msg ] [ MDBA_SET_ENTRY ] struct br_mdb_entry [ MDBA_SET_ENTRY_ATTRS ] [ MDBE_ATTR_SOURCE ] struct in_addr / struct in6_addr [ MDBE_ATTR_SRC_LIST ] // new [ MDBE_SRC_LIST_ENTRY ] [ MDBE_SRCATTR_ADDRESS ] struct in_addr / struct in6_addr [ ...] [ MDBE_ATTR_GROUP_MODE ] // new u8 Response: [ struct nlmsghdr ] [ struct br_port_msg ] [ MDBA_MDB ] [ MDBA_MDB_ENTRY ] [ MDBA_MDB_ENTRY_INFO ] struct br_mdb_entry [ MDBA_MDB_EATTR_TIMER ] u32 [ MDBA_MDB_EATTR_SOURCE ] struct in_addr / struct in6_addr [ MDBA_MDB_EATTR_RTPROT ] u8 [ MDBA_MDB_EATTR_SRC_LIST ] [ MDBA_MDB_SRCLIST_ENTRY ] [ MDBA_MDB_SRCATTR_ADDRESS ] struct in_addr / struct in6_addr [ MDBA_MDB_SRCATTR_TIMER ] u8 [...] [ MDBA_MDB_EATTR_GROUP_MODE ] u8 Signed-off-by: Ido Schimmel <idosch@nvidia.com> Acked-by: Nikolay Aleksandrov <razor@blackwall.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-12-12bridge: mcast: Add support for (*, G) with a source list and filter modeIdo Schimmel2-3/+132
In preparation for allowing user space to add (*, G) entries with a source list and associated filter mode, add the necessary plumbing to handle such requests. Extend the MDB configuration structure with a currently empty source array and filter mode that is currently hard coded to EXCLUDE. Add the source entries and the corresponding (S, G) entries before making the new (*, G) port group entry visible to the data path. Handle the creation of each source entry in a similar fashion to how it is created from the data path in response to received Membership Reports: Create the source entry, arm the source timer (if needed), add a corresponding (S, G) forwarding entry and finally mark the source entry as installed (by user space). Add the (S, G) entry by populating an MDB configuration structure and calling br_mdb_add_group_sg() as if a new entry is created by user space, with the sole difference that the 'src_entry' field is set to make sure that the group timer of such entries is never armed. Note that it is not currently possible to add more than 32 source entries to a port group entry. If this proves to be a problem we can either increase 'PG_SRC_ENT_LIMIT' or avoid forcing a limit on entries created by user space.

2022-12-12bridge: mcast: Avoid arming group timer when (S, G) corresponds to a sourceIdo Schimmel2-1/+2
User space will soon be able to install a (*, G) with a source list, prompting the creation of a (S, G) entry for each source. In this case, the group timer of the (S, G) entry should never be set. Solve this by adding a new field to the MDB configuration structure that denotes whether the (S, G) corresponds to a source or not. The field will be set in a subsequent patch where br_mdb_add_group_sg() is called in order to create a (S, G) entry for each user provided source.

2022-12-12bridge: mcast: Add a flag for user installed source entriesIdo Schimmel2-1/+3
There are a few places where the bridge driver differentiates between (S, G) entries installed by the kernel (in response to Membership Reports) and those installed by user space. One of them is when deleting an (S, G) entry corresponding to a source entry that is being deleted. While user space cannot currently add a source entry to a (*, G), it can add an (S, G) entry that later corresponds to a source entry created by the reception of a Membership Report. If this source entry is later deleted because its source timer expired or because the (*, G) entry is being deleted, the bridge driver will not delete the corresponding (S, G) entry if it was added by user space as permanent. This is going to be a problem when the ability to install a (*, G) with a source list is exposed to user space. In this case, when user space installs the (*, G) as permanent, then all the (S, G) entries corresponding to its source list will also be installed as permanent. When user space deletes the (*, G), all the source entries will be deleted and the expectation is that the corresponding (S, G) entries will be deleted as well. Solve this by introducing a new source entry flag denoting that the entry was installed by user space. When the entry is deleted, delete the corresponding (S, G) entry even if it was installed by user space as permanent, as the flag tells us that it was installed in response to the source entry being created. The flag will be set in a subsequent patch where source entries are created in response to user requests.

Expose __br_multicast_del_group_src() which is symmetric to br_multicast_new_group_src() and does not remove the installed {S, G} forwarding entry, unlike br_multicast_del_group_src().

As a preparatory step, expose br_multicast_new_group_src() so that it could later be invoked from the MDB code (i.e., br_mdb.c) that handles RTM_NEWMDB messages.

2022-12-12bridge: mcast: Add a centralized error pathIdo Schimmel1-4/+6
Subsequent patches will add memory allocations in br_mdb_config_init() as the MDB configuration structure will include a linked list of source entries. This memory will need to be freed regardless if br_mdb_add() succeeded or failed. As a preparation for this change, add a centralized error path where the memory will be freed.

2022-12-12bridge: mcast: Split (*, G) and (S, G) addition into different functionsIdo Schimmel1-49/+96
When the bridge is using IGMP version 3 or MLD version 2, it handles the addition of (*, G) and (S, G) entries differently. When a new (S, G) port group entry is added, all the (*, G) EXCLUDE ports need to be added to the port group of the new entry. Similarly, when a new (*, G) EXCLUDE port group entry is added, the port needs to be added to the port group of all the matching (S, G) entries. Subsequent patches will create more differences between both entry types. Namely, filter mode and source list can only be specified for (*, G) entries. Given the current and future differences between both entry types, handle the addition of each entry type in a different function, thereby avoiding the creation of one complex function.

2022-12-12bridge: mcast: Do not derive entry type from its filter modeIdo Schimmel1-6/+3
Currently, the filter mode (i.e., INCLUDE / EXCLUDE) of MDB entries cannot be set from user space. Instead, it is set by the kernel according to the entry type: (*, G) entries are treated as EXCLUDE and (S, G) entries are treated as INCLUDE. This allows the kernel to derive the entry type from its filter mode. Subsequent patches will allow user space to set the filter mode of (*, G) entries, making the current assumption incorrect. As a preparation, remove the current assumption and instead determine the entry type from its key, which is a more direct way.

2022-12-12net: add IFF_NO_ADDRCONF and use it in bonding to prevent ipv6 addrconfXin Long3-8/+17
Currently, in bonding it reused the IFF_SLAVE flag and checked it in ipv6 addrconf to prevent ipv6 addrconf. However, it is not a proper flag to use for no ipv6 addrconf, for bonding it has to move IFF_SLAVE flag setting ahead of dev_open() in bond_enslave(). Also, IFF_MASTER/SLAVE are historical flags used in bonding and eql, as Jiri mentioned, the new devices like Team, Failover do not use this flag. So as Jiri suggested, this patch adds IFF_NO_ADDRCONF in priv_flags of the device to indicate no ipv6 addconf, and uses it in bonding and moves IFF_SLAVE flag setting back to its original place.

In applications where the switch ports must perform 802.1X based authentication and are therefore locked, ATU violation interrupts are quite to be expected as part of normal operation. The problem is that they currently spam the kernel log, even if rate limited. Create a series of trace points, all derived from the same event class, which log these violations to the kernel's trace buffer, which is both much faster and much easier to ignore than printing to a serial console.

2022-12-12net: dsa: mv88e6xxx: read FID when handling ATU violationsHans J. Schultz1-11/+61
When an ATU violation occurs, the switch uses the ATU FID register to report the FID of the MAC address that incurred the violation. It would be good for the driver to know the FID value for purposes such as logging and CPU-based authentication. Up until now, the driver has been calling the mv88e6xxx_g1_atu_op() function to read ATU violations, but that doesn't do exactly what we want, namely it calls mv88e6xxx_g1_atu_fid_write() with FID 0. (side note, the documentation for the ATU Get/Clear Violation command says that writes to the ATU FID register have no effect before the operation starts, it's only that we disregard the value that this register provides once the operation completes) So mv88e6xxx_g1_atu_fid_write() is not what we want, but rather mv88e6xxx_g1_atu_fid_read(). However, the latter doesn't exist, we need to write it. The remainder of mv88e6xxx_g1_atu_op() except for mv88e6xxx_g1_atu_fid_write() is still needed, namely to send a GET_CLR_VIOLATION command to the ATU. In principle we could have still kept calling mv88e6xxx_g1_atu_op(), but the MDIO writes to the ATU FID register are pointless, but in the interest of doing less CPU work per interrupt, write a new function called mv88e6xxx_g1_read_atu_violation() and call it. The FID will be the port default FID as set by mv88e6xxx_port_set_fid() if the VID from the packet cannot be found in the VTU. Otherwise it is the FID derived from the VTU entry associated with that VID. Signed-off-by: Hans J.
