Commit 406f42fa ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it go through appropriate helpers. Make sure local references to netdev->dev_addr are constant. Signed-off-by:

Vladimir Oltean says: ==================== Drop rtnl_lock from DSA .port_fdb_{add,del} As mentioned in the RFC posted 2 months ago: https://patchwork.kernel.org/project/netdevbpf/cover/20210824114049.3814660-1-vladimir.oltean@nxp.com/ DSA is transitioning to a driver API where the rtnl_lock is not held when calling ds->ops->port_fdb_add() and ds->ops->port_fdb_del(). Drivers cannot take that lock privately from those callbacks either. This change is required so that DSA can wait for switchdev FDB work items to finish before leaving the bridge. That change will be made in a future patch series. A small selftest is provided with the patch set in the hope that concurrency issues uncovered by this series, but not spotted by me by code inspection, will be caught. A status of the existing drivers: - mv88e6xxx_port_fdb_add() and mv88e6xxx_port_fdb_del() take mv88e6xxx_reg_lock() so they should be safe. - qca8k_fdb_add() and qca8k_fdb_del() take mutex_lock(&priv->reg_mutex) so they should be safe. - hellcreek_fdb_add() and hellcreek_fdb_add() take mutex_lock(&hellcreek->reg_lock) so they should be safe. - ksz9477_port_fdb_add() and ksz9477_port_fdb_del() take mutex_lock(&dev->alu_mutex) so they should be safe. - b53_fdb_add() and b53_fdb_del() did not have locking, so I've added a scheme based on my own judgement there (not tested). - felix_fdb_add() and felix_fdb_del() did not have locking, I've added and tested a locking scheme there. - mt7530_port_fdb_add() and mt7530_port_fdb_del() take mutex_lock(&priv->reg_mutex), so they should be safe. - gswip_port_fdb() did not have locking, so I've added a non-expert locking scheme based on my own judgement (not tested). - lan9303_alr_add_port() and lan9303_alr_del_port() take mutex_lock(&chip->alr_mutex) so they should be safe. - sja1105_fdb_add() and sja1105_fdb_del() did not have locking, I've added and tested a locking scheme. ==================== Signed-off-by: -

This test is a bit strange in that it is perhaps more manual than others: it does not transmit a clear OK/FAIL verdict, because user space does not have synchronous feedback from the kernel. If a hardware access fails, it is in deferred context. Nonetheless, on sja1105 I have used it successfully to find and solve a concurrency issue, so it can be used as a starting point for other driver maintainers too. Signed-off-by:

These programs are useful, but not all selftests require them. Additionally, on embedded boards without package management (things like buildroot), installing mausezahn or jq is not always as trivial as downloading a package from the web. So it is actually a bit annoying to require programs that are not used. Introduce options that can be set by scripts to not enforce these dependencies. For compatibility, default to "yes".

After talking with Ido Schimmel, it became clear that rtnl_lock is not actually required for anything that is done inside the SWITCHDEV_FDB_{ADD,DEL}_TO_DEVICE deferred work handlers. The reason why it was probably added by Arkadi Sharshevsky in commit c9eb3e0f ("net: dsa: Add support for learning FDB through notification") was to offer the same locking/serialization guarantees as .ndo_fdb_{add,del} and avoid reworking any drivers. DSA has implemented .ndo_fdb_add and .ndo_fdb_del until commit b117e1e8 ("net: dsa: delete dsa_legacy_fdb_add and dsa_legacy_fdb_del") - that is to say, until fairly recently. But those methods have been deleted, so now we are free to drop the rtnl_lock as well. Note that exposing DSA switch drivers to an unlocked method which was previously serialized by the rtnl_mutex is a potentially dangerous affair. Driver writers couldn't ensure that their internal locking scheme does the right thing even if they wanted. We could err on the side of paranoia and introduce a switch-wide lock inside the DSA framework, but that seems way overreaching. Instead, we could check as many drivers for regressions as we can, fix those first, then let this change go in once it is assumed to be fairly safe. Signed-off-by: -

Now that the rtnl_mutex is going away for dsa_port_{host_,}fdb_{add,del}, no one is serializing access to the address lists that DSA keeps for the purpose of reference counting on shared ports (CPU and cascade ports). It can happen for one dsa_switch_do_fdb_del to do list_del on a dp->fdbs element while another dsa_switch_do_fdb_{add,del} is traversing dp->fdbs. We need to avoid that. Currently dp->mdbs is not at risk, because dsa_switch_do_mdb_{add,del} still runs under the rtnl_mutex. But it would be nice if it would not depend on that being the case. So let's introduce a mutex per port (the address lists are per port too) and share it between dp->mdbs and dp->fdbs. The place where we put the locking is interesting. It could be tempting to put a DSA-level lock which still serializes calls to .port_fdb_{add,del}, but it would still not avoid concurrency with other driver code paths that are currently under rtnl_mutex (.port_fdb_dump, .port_fast_age). So it would add a very false sense of security (and adding a global switch-wide lock in DSA to resynchronize with the rtnl_lock is also counterproductive and hard). So the locking is intentionally done only where the dp->fdbs and dp->mdbs lists are traversed. That means, from a driver perspective, that .port_fdb_add will be called with the dp->addr_lists_lock mutex held on the CPU port, but not held on user ports. This is done so that driver writers are not encouraged to rely on any guarantee offered by dp->addr_lists_lock. Signed-off-by: -

Looking at the code, the GSWIP switch appears to hold bridging service structures (VLANs, FDBs, forwarding rules) in PCE table entries. Hardware access to the PCE table is non-atomic, and is comprised of several register reads and writes. These accesses are currently serialized by the rtnl_lock, but DSA is changing its driver API and that lock will no longer be held when calling ->port_fdb_add() and ->port_fdb_del(). So this driver needs to serialize the access to the PCE table using its own locking scheme. This patch adds that. Signed-off-by:

The b53 driver performs non-atomic transactions to the ARL table when adding, deleting and reading FDB and MDB entries. Traditionally these were all serialized by the rtnl_lock(), but now it is possible that DSA calls ->port_fdb_add and ->port_fdb_del without holding that lock. So the driver must have its own serialization logic. Add a mutex and hold it from all entry points (->port_fdb_{add,del,dump}, ->port_mdb_{add,del}). Signed-off-by: -

DSA would like to remove the rtnl_lock from its SWITCHDEV_FDB_{ADD,DEL}_TO_DEVICE handlers, and the felix driver uses the same MAC table functions as ocelot. This means that the MAC table functions will no longer be implicitly serialized with respect to each other by the rtnl_mutex, we need to add a dedicated lock in ocelot for the non-atomic operations of selecting a MAC table row, reading/writing what we want and polling for completion.

The sja1105 hardware seems as concurrent as can be, but when we create a background script that adds/removes a rain of FDB entries without the rtnl_mutex taken, then in parallel we do another operation like run 'bridge fdb show', we can notice these errors popping up: sja1105 spi2.0: port 2 failed to read back entry for 00:01:02:03:00:40 vid 0: -ENOENT sja1105 spi2.0: port 2 failed to add 00:01:02:03:00:40 vid 0 to fdb: -2 sja1105 spi2.0: port 2 failed to read back entry for 00:01:02:03:00:46 vid 0: -ENOENT sja1105 spi2.0: port 2 failed to add 00:01:02:03:00:46 vid 0 to fdb: -2 Luckily what is going on does not require a major rework in the driver. The sja1105_dynamic_config_read() function sends multiple SPI buffers to the peripheral until the operation completes. We should not do anything until the hardware clears the VALID bit. But since there is no locking (i.e. right now we are implicitly serialized by the rtnl_mutex, but if we remove that), it might be possible that the process which performs the dynamic config read is preempted and another one performs a dynamic config write. What will happen in that case is that sja1105_dynamic_config_read(), when it resumes, expects to see VALIDENT set for the entry it reads back. But it won't. This can be corrected by introducing a mutex for serializing SPI accesses to the dynamic config interface which should be atomic with respect to each other. Signed-off-by:

Vladimir Oltean authored
The hardware manual says that software should attempt a new dynamic config access (be it a a write or a read-back) only while the VALID bit is cleared. The VALID bit is set by software to 1, and it remains set as long as the hardware is still processing the request. Currently the driver only polls for the command completion only for reads, because that's when we need the actual data read back. Writes have been more or less "asynchronous", although this has never been an observable issue. This change makes sja1105_dynamic_config_write poll the VALID bit as well, to absolutely ensure that a follow-up access to the static config finds the VALID bit cleared. So VALID means "work in progress", while VALIDENT means "entry being read is valid". On reads we check the VALIDENT bit too, while on writes that bit is not always defined. So we need to factor it out of the loop, and make the loop provide back the unpacked command structure, so that sja1105_dynamic_config_read can check the VALIDENT bit. The change also attempts to convert the open-coded loop to use the read_poll_timeout macro, since I know this will come up during review. It's more code, but hey, it uses read_poll_timeout! Tested on SJA1105T, SJA1105S, SJA1110A. Signed-off-by:

This adds an optional mdio bus child node. If present, the mac will look for PHYs there instead of directly under the top-level node. This eliminates any ambiguity about whether child nodes are PHYs, and allows the MDIO bus to contain non-PHY devices. Signed-off-by:

The 16nm internal EPHY that is present in 7712 is actually a 16nm Gigabit PHY which has been forced to operate in 10/100 mode. Its controls are therefore via the EXT_GPHY_CTRL registers and not via the EXT_EPHY_CTRL which are used for all GENETv5 adapters. Add a match on the 7712 compatible string to allow that differentiation to happen. On previous GENETv4 chips the EXT_CFG_IDDQ_GLOBAL_PWR bit was cleared by default, but this is not the case with this chip, so we need to make sure we clear it to power on the EPHY. Signed-off-by:
