2023-08-24bonding: fix macvlan over alb bond supportHangbin Liu
The commit 14af9963ba1e ("bonding: Support macvlans on top of tlb/rlb mode bonds") aims to enable the use of macvlans on top of rlb bond mode. However, the current rlb bond mode only handles ARP packets to update remote neighbor entries. This causes an issue when a macvlan is on top of the bond, and remote devices send packets to the macvlan using the bond's MAC address as the destination. After delivering the packets to the macvlan, the macvlan will rejects them as the MAC address is incorrect. Consequently, this commit makes macvlan over bond non-functional. To address this problem, one potential solution is to check for the presence of a macvlan port on the bond device using netif_is_macvlan_port(bond->dev) and return NULL in the rlb_arp_xmit() function. However, this approach doesn't fully resolve the situation when a VLAN exists between the bond and macvlan. So let's just do a partial revert for commit 14af9963ba1e in rlb_arp_xmit(). As the comment said, Don't modify or load balance ARPs that do not originate locally.

2023-08-22bnx2x: new flag for track HW resource allocationThinh Tran
While injecting PCIe errors to the upstream PCIe switch of a BCM57810 NIC, system hangs/crashes were observed. After several calls to bnx2x_tx_timout() complete, bnx2x_nic_unload() is called to free up HW resources and bnx2x_napi_disable() is called to release NAPI objects. Later, when the EEH driver calls bnx2x_io_slot_reset() to complete the recovery process, bnx2x attempts to disable NAPI again by calling bnx2x_napi_disable() and freeing resources which have already been freed, resulting in a hang or crash. Introduce a new flag to track the HW resource and NAPI allocation state, refactor duplicated code into a single function, check page pool allocation status before freeing, and reduces debug output when a TX timeout event occurs.

2023-08-22sfc: allocate a big enough SKB for loopback selftest packetEdward Cree
Cited commits passed a size to alloc_skb that was only big enough for the actual packet contents, but the following skb_put + memcpy writes the whole struct efx_loopback_payload including leading and trailing padding bytes (which are then stripped off with skb_pull/skb_trim). This could cause an skb_over_panic, although in practice we get saved by kmalloc_size_roundup. Pass the entire size we use, instead of the size of the final packet.

2023-08-22leds: trigger: netdev: rename 'hw_control' sysfs entry to 'offloaded'Marek Behún
Commit b655892ffd6d ("leds: trigger: netdev: expose hw_control status via sysfs") exposed to sysfs the flag that tells whether the LED trigger is offloaded to hardware, under the name "hw_control", since that is the name under which this setting is called in the code. Everywhere else in kernel when some work that is normally done in software can be made to be done by hardware instead, we use the word "offloading" to describe this, e.g. "LED blinking is offloaded to hardware". Normally renaming sysfs entries is a no-go because of backwards compatibility. But since this patch was not yet released in a stable kernel, I think it is still possible to rename it, if there is consensus.

2023-08-21ice: Fix NULL pointer deref during VF resetPetr Oros
During stress test with attaching and detaching VF from KVM and simultaneously changing VFs spoofcheck and trust there was a NULL pointer dereference in ice_reset_vf that VF's VSI is null. More than one instance of ice_reset_vf() can be running at a given time. When we rebuild the VSI in ice_reset_vf, another reset can be triaged from ice_service_task. In this case we can access the currently uninitialized VSI and cause panic. The window for this racing condition has been around for a long time but it's much worse after commit 227bf4500aaa ("ice: move VSI delete outside deconfig") because the reset runs faster. ice_reset_vf() using vf->cfg_lock and when we move this lock before accessing to the VF VSI, we can fix BUG for all cases. Panic occurs sometimes in ice_vsi_is_rx_queue_active() and sometimes in ice_vsi_stop_all_rx_rings() With our reproducer, we can hit BUG: ~8h before commit 227bf4500aaa ("ice: move VSI delete outside deconfig"). ~20m after commit 227bf4500aaa ("ice: move VSI delete outside deconfig"). After this fix we are not able to reproduce it after ~48h There was commit cf90b74341ee ("ice: Fix call trace with null VSI during VF reset") which also tried to fix this issue, but it was only partially resolved and the bug still exists.

2023-08-21ice: fix receive buffer size miscalculationJesse Brandeburg
The driver is misconfiguring the hardware for some values of MTU such that it could use multiple descriptors to receive a packet when it could have simply used one. Change the driver to use a round-up instead of the result of a shift, as the shift can truncate the lower bits of the size, and result in the problem noted above. It also aligns this driver with similar code in i40e. The insidiousness of this problem is that everything works with the wrong size, it's just not working as well as it could, as some MTU sizes end up using two or more descriptors, and there is no way to tell that is happening without looking at ice_trace or a bus analyzer.

2023-08-19net: phy: Fix deadlocking in phy_error() invocationSerge Semin
Since commit 91a7cda1f4b8 ("net: phy: Fix race condition on link status change") all the phy_error() method invocations have been causing the nested-mutex-lock deadlock because it's normally done in the PHY-driver threaded IRQ handlers which since that change have been called with the phydev->lock mutex held.

Fix it by dropping the phydev->lock mutex lock from the phy_process_error() method and printing a nasty error message to the system log if the mutex isn't held in the caller execution context. Note for the fix to work correctly in the PHY-subsystem itself the phydev->lock mutex locking must be added to the phy_error_precise() function.

2023-08-19net: sfp: handle 100G/25G active optical cables in sfp_parse_supportJosua Mayer
Handle extended compliance code 0x1 (SFF8024_ECC_100G_25GAUI_C2M_AOC) for active optical cables supporting 25G and 100G speeds. Since the specification makes no statement about transmitter range, and as the specific sfp module that had been tested features only 2m fiber - short-range (SR) modes are selected. The 100G speed is irrelevant because it would require multiple fibers / multiple SFP28 modules combined under one netdev. sfp-bus.c only handles a single module per netdev, so only 25Gbps modes are selected. sfp_parse_support already handles SFF8024_ECC_100GBASE_SR4_25GBASE_SR with compatible properties, however that entry is a contradiction in itself since with SFP(28) 100GBASE_SR4 is impossible - that would likely be a mode for qsfp modules only. Add a case for SFF8024_ECC_100G_25GAUI_C2M_AOC selecting 25gbase-r interface mode and 25000baseSR link mode. Also enforce SFP28 bitrate limits on the values read from sfp eeprom as requested by Russell King. Tested with fs.com S28-AO02 AOC SFP28 module.

2023-08-19net: mdio: mdio-bitbang: Fix C45 read/write protocolSerge Semin
Based on the original code semantic in case of Clause 45 MDIO, the address command is supposed to be followed by the command sending the MMD address, not the CSR address. The commit 002dd3de097c ("net: mdio: mdio-bitbang: Separate C22 and C45 transactions") has erroneously broken that. So most likely due to an unfortunate variable name it switched the code to sending the CSR address. In our case it caused the protocol malfunction so the read operation always failed with the turnaround bit always been driven to one by PHY instead of zero. Fix that by getting back the correct behaviour: sending MMD address command right after the regular address command.

2023-08-18mlxsw: Fix the size of 'VIRT_ROUTER_MSB'Amit Cohen
The field 'virtual router' was extended to 12 bits in Spectrum-4. Therefore, the element 'MLXSW_AFK_ELEMENT_VIRT_ROUTER_MSB' needs 3 bits for Spectrum < 4 and 4 bits for Spectrum >= 4. The elements are stored in an internal storage scratchpad. Currently, the MSB is defined there as 3 bits. It means that for Spectrum-4, only 2K VRFs can be used for multicast routing, as the highest bit is not really used by the driver. Fix the definition of 'VIRT_ROUTER_MSB' to use 4 bits. Adjust the definitions of 'virtual router' field in the blocks accordingly - use '_avoid_size_check' for Spectrum-2 instead of for Spectrum-4. Fix the mask in parse function to use 4 bits.

The two most significant bits of the "local_port" field in the SSPR register are always cleared since they are overwritten by the deprecated and overlapping "sub_port" field. On systems with more than 255 local ports (e.g., Spectrum-4), this results in the firmware maintaining invalid mappings between system port and local port. Specifically, two different systems ports (0x1 and 0x101) point to the same local port (0x1), which eventually leads to firmware errors. Fix by removing the deprecated "sub_port" field.

Currently, in Spectrum-2 and above, time stamps are extracted from the CQE into the time stamp fields in 'struct mlxsw_skb_cb', only when the CQE time stamp type is UTC. The time stamps are read directly from the CQE and software can get the time stamp in UTC format using CQEv2. From Spectrum-4, the time stamps that are read from the CQE are allowed to be also from MIRROR_UTC type. Therefore, we get a warning [1] from the driver that the time stamp fields were not set, when LLDP control packet is sent. Allow the time stamp type to be MIRROR_UTC and set the time stamp in this case as well.

There are two network devices(veth1 and veth3) in ns1, and ipvlan1 with L3S mode and ipvlan2 with L2 mode are created based on them as figure (1). In this case, ipvlan_register_nf_hook() will be called to register nf hook which is needed by ipvlans in L3S mode in ns1 and value of ipvl_nf_hook_refcnt is set to 1. (1) ns1 ns2 ------------ ------------ veth1--ipvlan1 (L3S) veth3--ipvlan2 (L2) (2) ns1 ns2 ------------ ------------ veth1--ipvlan1 (L3S) ipvlan2 (L2) veth3 | | |------->-------->--------->-------- migrate When veth3 migrates from ns1 to ns2 as figure (2), veth3 will register in ns2 and calls call_netdevice_notifiers with NETDEV_REGISTER event: dev_change_net_namespace call_netdevice_notifiers ipvlan_device_event ipvlan_migrate_l3s_hook ipvlan_register_nf_hook(newnet) (I) ipvlan_unregister_nf_hook(oldnet) (II) In function ipvlan_migrate_l3s_hook(), ipvl_nf_hook_refcnt in ns1 is not 0 since veth1 with ipvlan1 still in ns1, (I) and (II) will be called to register nf_hook in ns2 and unregister nf_hook in ns1. As a result, ipvl_nf_hook_refcnt in ns1 is decreased incorrectly and this in ns2 is increased incorrectly. When the second net namespace is removed, a reference count leak warning in ipvlan_ns_exit() will be triggered. This patch add a check before ipvlan_migrate_l3s_hook() is called.

2023-08-18net: dsa: felix: fix oversize frame dropping for always closed tc-taprio gatesVladimir Oltean
The blamed commit resolved a bug where frames would still get stuck at egress, even though they're smaller than the maxSDU[tc], because the driver did not take into account the extra 33 ns that the queue system needs for scheduling the frame. It now takes that into account, but the arithmetic that we perform in vsc9959_tas_remaining_gate_len_ps() is buggy, because we operate on 64-bit unsigned integers, so gate_len_ns - VSC9959_TAS_MIN_GATE_LEN_NS may become a very large integer if gate_len_ns < 33 ns. In practice, this means that we've introduced a regression where all traffic class gates which are permanently closed will not get detected by the driver, and we won't enable oversize frame dropping for them.
