In L2 tests that filter packets by destination MAC address we need to prevent false positives that can occur if we add an address that collides with the existing ones. To fix this, lets manually check if the new address to be added is already present in the NIC and use a different one if so. For Hash filtering this also envolves converting the address to the hash.

Jakub Kicinski says: ==================== net/tls: add a TX lock Some time ago Pooja and Mallesham started reporting crashes with an async accelerator. After trying to poke the existing logic into shape I came to the conclusion that it can't be trusted, and to preserve our sanity we should just add a lock around the TX side. First patch removes the sk_write_pending checks from the write space callbacks. Those don't seem to have a logical justification. Patch 2 adds the TX lock and patch 3 associated test (which should hang with current net). Mallesham reports that even with these fixes applied the async accelerator workload still occasionally hangs waiting for socket memory. I suspect that's strictly related to the way async crypto is integrated in TLS, so I think we should get these into net or net-next and move from there. ==================== Signed-off-by: -

TLS TX needs to release and re-acquire the socket lock if send buffer fills up. TLS SW TX path currently depends on only allowing one thread to enter the function by the abuse of sk_write_pending. If another writer is already waiting for memory no new ones are allowed in. This has two problems: - writers don't wake other threads up when they leave the kernel; meaning that this scheme works for single extra thread (second application thread or delayed work) because memory becoming available will send a wake up request, but as Mallesham and Pooja report with larger number of threads it leads to threads being put to sleep indefinitely; - the delayed work does not get _scheduled_ but it may _run_ when other writers are present leading to crashes as writers don't expect state to change under their feet (same records get pushed and freed multiple times); it's hard to reliably bail from the work, however, because the mere presence of a writer does not guarantee that the writer will push pending records before exiting. Ensuring wakeups always happen will make the code basically open code a mutex. Just use a mutex. The TLS HW TX path does not have any locking (not even the sk_write_pending hack), yet it uses a per-socket sg_tx_data array to push records.

sk_write_pending being not zero does not guarantee that partial record will be pushed. If the thread waiting for memory times out the pending record may get stuck. In case of tls_device there is no path where parial record is set and writer present in the first place. Partial record is set only in tls_push_sg() and tls_push_sg() will return an error immediately. All tls_device callers of tls_push_sg() will return (and not wait for memory) if it failed.

The "read-modify-write register index" function is declared with a confusing prototype: the "mask" and "reg" arguments are swapped. Fortunately, this does not affect callers so far. Both arguments are u32, and the wrapper macros (ocelot_rmw_ix etc) have the arguments in the correct order (the one from ocelot_io.c). Signed-off-by:

Doug Berger says: ==================== net: bcmgenet: restore internal EPHY support (part 2) This is a follow up to my previous submission (see [1]). The first commit provides what is intended to be a complete solution for the issues that can result from insufficient clocking of the MAC during reset of its state machines. It should be backported to the stable releases. It is intended to replace the partial solution of commit 1f515486 ("net: bcmgenet: soft reset 40nm EPHYs before MAC init") which is reverted by the second commit of this series and should not be back- ported as noted in [2]. The third commit corrects a timing hazard with a polled PHY that can occur when the MAC resumes and also when a v3 internal EPHY is reset by the change in commit 25382b99 ("net: bcmgenet: reset 40nm EPHY on energy detect"). It is expected that commit 25382b99 be back- ported to stable first before backporting this commit.

The phy_init_hw() function may reset the PHY to a configuration that does not match manual network settings stored in the phydev structure. If the phy state machine is polled rather than event driven this can create a timing hazard where the phy state machine might alter the settings stored in the phydev structure from the value read from the BMCR. This commit follows invocations of phy_init_hw() by the bcmgenet driver with invocations of the genphy_config_aneg() function to ensure that the BMCR is written to match the settings held in the phydev structure. This prevents the risk of manual settings being accidentally altered. Fixes: 1c1008c7 ("net: bcmgenet: add main driver file") Signed-off-by:

This reverts commit 1f515486. This commit improved the chances of the umac resetting cleanly by ensuring that the PHY was restored to its normal operation prior to resetting the umac. However, there were still cases when the PHY might not be driving a Tx clock to the umac during this window (e.g. when the PHY detects no link). The previous commit now ensures that the unimac receives clocks from the MAC during its reset window so this commit is no longer needed. This commit also has an unintended negative impact on the MDIO performance of the UniMAC MDIO interface because it is used before the MDIO interrupts are reenabled, so it should be removed.

Doug Berger authored
As noted in commit 28c2d1a7 ("net: bcmgenet: enable loopback during UniMAC sw_reset") the UniMAC must be clocked while sw_reset is asserted for its state machines to reset cleanly. The transmit and receive clocks used by the UniMAC are derived from the signals used on its PHY interface. The bcmgenet MAC can be configured to work with different PHY interfaces including MII, GMII, RGMII, and Reverse MII on internal and external interfaces. Unfortunately for the UniMAC, when configured for MII the Tx clock is always driven from the PHY which places it outside of the direct control of the MAC. The earlier commit enabled a local loopback mode within the UniMAC so that the receive clock would be derived from the transmit clock which addressed the observed issue with an external GPHY disabling it's Rx clock. However, when a Tx clock is not available this loopback is insufficient. This commit implements a workaround that leverages the fact that the MAC can reliably generate all of its necessary clocking by enterring the external GPHY RGMII interface mode with the UniMAC in local loopback during the sw_reset interval. Unfortunately, this has the undesirable side efect of the RGMII GTXCLK signal being driven during the same window. In most configurations this is a benign side effect as the signal is either not routed to a pin or is already expected to drive the pin. The one exception is when an external MII PHY is expected to drive the same pin with its TX_CLK output creating output driver contention. This commit exploits the IEEE 802.3 clause 22 standard defined isolate mode to force an external MII PHY to present a high impedance on its TX_CLK output during the window to prevent any contention at the pin. The MII interface is used internally with the 40nm internal EPHY which agressively disables its clocks for power savings leading to incomplete resets of the UniMAC and many instabilities observed over the years. The workaround of this commit is expected to put an end to those problems. Fixes: 1c1008c7 ("net: bcmgenet: add main driver file") Signed-off-by:

During the exit/unregistration process of the RmNet driver, the function rmnet_unregister_real_device() is called to handle freeing the driver's internal state and removing the RX handler on the underlying physical device. However, the order of operations this function performs is wrong and can lead to a use after free of the rmnet_port structure. Before calling netdev_rx_handler_unregister(), this port structure is freed with kfree(). If packets are received on any RmNet devices before synchronize_net() completes, they will attempt to use this already-freed port structure when processing the packet. As such, before cleaning up any other internal state, the RX handler must be unregistered in order to guarantee that no further packets will arrive on the device.

sk_msg_trim() tries to only update curr pointer if it falls into the trimmed region. The logic, however, does not take into the account pointer wrapping that sk_msg_iter_var_prev() does nor (as John points out) the fact that msg->sg is a ring buffer. This means that when the message was trimmed completely, the new curr pointer would have the value of MAX_MSG_FRAGS - 1, which is neither smaller than any other value, nor would it actually be correct. Special case the trimming to 0 length a little bit and rework the comparison between curr and end to take into account wrapping. This bug caused the TLS code to not copy all of the message, if zero copy filled in fewer sg entries than memcopy would need. Big thanks to Alexander Potapenko for the non-KMSAN reproducer. v2: - take into account that msg->sg is a ring buffer (John).

When a new filter is added to cls_api, the function tcf_chain_tp_insert_unique() looks up the protocol/priority/chain to determine if the tcf_proto is duplicated in the chain's hashtable. It then creates a new entry or continues with an existing one. In cls_flower, this allows the function fl_ht_insert_unque to determine if a filter is a duplicate and reject appropriately, meaning that the duplicate will not be passed to drivers via the offload hooks. However, when a tcf_proto is destroyed it is removed from its chain before a hardware remove hook is hit. This can lead to a race whereby the driver has not received the remove message but duplicate flows can be accepted. This, in turn, can lead to the offload driver receiving incorrect duplicate flows and out of order add/delete messages. Prevent duplicates by utilising an approach suggested by Vlad Buslov. A hash table per block stores each unique chain/protocol/prio being destroyed. This entry is only removed when the full destroy (and hardware offload) has completed. If a new flow is being added with the same identiers as a tc_proto being detroyed, then the add request is replayed until the destroy is complete.

Since de77ecd4 ("bonding: improve link-status update in mii-monitoring"), the bonding driver has utilized two separate variables to indicate the next link state a particular slave should transition to. Each is used to communicate to a different portion of the link state change commit logic; one to the bond_miimon_commit function itself, and another to the state transition logic. Unfortunately, the two variables can become unsynchronized, resulting in incorrect link state transitions within bonding. This can cause slaves to become stuck in an incorrect link state until a subsequent carrier state transition. The issue occurs when a special case in bond_slave_netdev_event sets slave->link directly to BOND_LINK_FAIL. On the next pass through bond_miimon_inspect after the slave goes carrier up, the BOND_LINK_FAIL case will set the proposed next state (link_new_state) to BOND_LINK_UP, but the new_link to BOND_LINK_DOWN. The setting of the final link state from new_link comes after that from link_new_state, and so the slave will end up incorrectly in _DOWN state. Resolve this by combining the two variables into one.
