In the smc_listen_work(), if smc_listen_prfx_check() failed, the real reason: SMC_CLC_DECL_DIFFPREFIX was dropped, and SMC_CLC_DECL_NOSMCDEV was returned. Althrough this is also kind of SMC_CLC_DECL_NOSMCDEV, but return the real reason is much friendly for debugging. Fixes: e49300a6 ("net/smc: add listen processing for SMC-Rv2") Signed-off-by:

Kernels that don't have support for openvswitch drop reasons also won't have the drop counter reasons, so we should skip the test completely. It previously wasn't possible to build a test case for this without polluting the datapath, so we introduce a mechanism to clear all the flows from a datapath allowing us to test for explicit drop actions, and then clear the flows to build the original test case.

Paolo Abeni reports that on some systems the pyroute2 version isn't new enough to run the test suite. Ensure that we support a minimum version of 0.6 for all cases (which does include the existing ones). The 0.6.1 version was released in May of 2021, so should be propagated to most installations at this point. The alternative that Paolo proposed was to only skip when the add-flow is being run. This would be okay for most cases, except if a future test case is added that needs to do flow dump without an associated add (just guessing). In that case, it could also be broken and we would need additional skip logic anyway. Just draw a line in the sand now. Fixes: 25f16c87 ("selftests: add openvswitch selftest suite") Reported-by:

When the system boots into the crash dump kernel after a panic, the ice networking device may still have pending transactions that can cause errors or machine checks when the device is re-enabled. This can prevent the crash dump kernel from loading the driver or collecting the crash data. To avoid this issue, perform a function level reset (FLR) on the ice device via PCIe config space before enabling it on the crash kernel. This will clear any outstanding transactions and stop all queues and interrupts. Restore the config space after the FLR, otherwise it was found in testing that the driver wouldn't load successfully. The following sequence causes the original issue: - Load the ice driver with modprobe ice - Enable SR-IOV with 2 VFs: echo 2 > /sys/class/net/eth0/device/sriov_num_vfs - Trigger a crash with echo c > /proc/sysrq-trigger - Load the ice driver again (or let it load automatically) with modprobe ice - The system crashes again during pcim_enable_device() Fixes: 837f08fd ("ice: Add basic driver framework for Intel(R) E800 Series") Reported-by:

The hardware provides the indexes of the first and the last available queue and VF. From the indexes, the driver calculates the numbers of queues and VFs. In theory, a faulty device might say the last index is smaller than the first index. In that case, the driver's calculation would underflow, it would attempt to write to non-existent registers outside of the ioremapped range and crash. I ran into this not by having a faulty device, but by an operator error. I accidentally ran a QE test meant for i40e devices on an ice device. The test used 'echo i40e > /sys/...ice PCI device.../driver_override', bound the driver to the device and crashed in one of the wr32 calls in i40e_clear_hw. Add checks to prevent underflows in the calculations of num_queues and num_vfs. With this fix, the wrong device probing reports errors and returns a failure without crashing.

I took this for net instead of -next given infra is already in place and no actual code change is made. Patch 4, from Pablo Neira Ayso, disables timeout resets on stateful element reset.

Broken since feature was added in 6.2, fixes from Xingyuan Mo.

As reported by Tom, .NET and applications build on top of it rely on connect(AF_UNSPEC) to async cancel pending I/O operations on TCP socket. The blamed commit below caused a regression, as such cancellation can now fail. As suggested by Eric, this change addresses the problem explicitly causing blocking I/O operation to terminate immediately (with an error) when a concurrent disconnect() is executed. Instead of tracking the number of threads blocked on a given socket, track the number of disconnect() issued on such socket. If such counter changes after a blocking operation releasing and re-acquiring the socket lock, error out the current operation.

In bcm_sf2_mdio_register(), the class_find_device() will call get_device() to increment reference count for priv->master_mii_bus->dev if of_mdio_find_bus() succeeds. If mdiobus_alloc() or mdiobus_register() fails, it will call get_device() twice without decrement reference count for the device. And it is the same if bcm_sf2_mdio_register() succeeds but fails in bcm_sf2_sw_probe(), or if bcm_sf2_sw_probe() succeeds. If the reference count has not decremented to zero, the dev related resource will not be freed. So remove the get_device() in bcm_sf2_mdio_register(), and call put_device() if mdiobus_alloc() or mdiobus_register() fails and in bcm_sf2_mdio_unregister() to solve the issue. And as Simon suggested, unwind from errors for bcm_sf2_mdio_register() and just return 0 if it succeeds to make it cleaner.

syzbot reported a warning [0] introduced by commit c48ef9c4 ("tcp: Fix bind() regression for v4-mapped-v6 non-wildcard address."). After the cited commit, a v4 socket's address matches the corresponding v4-mapped-v6 tb2 in inet_bind2_bucket_match_addr(), not vice versa. During X.X.X.X -> ::ffff:X.X.X.X order bind()s, the second bind() uses bhash and conflicts properly without checking bhash2 so that we need not check if a v4-mapped-v6 sk matches the corresponding v4 address tb2 in inet_bind2_bucket_match_addr(). However, the repro shows that we need to check that in a no-conflict case. The repro bind()s two sockets to the 2-tuples using SO_REUSEPORT and calls listen() for the first socket: from socket import * s1 = socket() s1.setsockopt(SOL_SOCKET, SO_REUSEPORT, 1) s1.bind(('127.0.0.1', 0)) s2 = socket(AF_INET6) s2.setsockopt(SOL_SOCKET, SO_REUSEPORT, 1) s2.bind(('::ffff:127.0.0.1', s1.getsockname()[1])) s1.listen() The second socket should belong to the first socket's tb2, but the second bind() creates another tb2 bucket because inet_bind2_bucket_find() returns NULL in inet_csk_get_port() as the v4-mapped-v6 sk does not match the corresponding v4 address tb2. bhash2[] -> tb2(::ffff:X.X.X.X) -> tb2(X.X.X.X) Then, listen() for the first socket calls inet_csk_get_port(), where the v4 address matches the v4-mapped-v6 tb2 and WARN_ON() is triggered. To avoid that, we need to check if v4-mapped-v6 sk address matches with the corresponding v4 address tb2 in inet_bind2_bucket_match(). The same checks are needed in inet_bind2_bucket_addr_match() too, so we can move all checks there and call it from inet_bind2_bucket_match(). Note that now tb->family is just an address family of tb->(v6_)?rcv_saddr and not of sockets in the bucket. This could be refactored later by defining tb->rcv_saddr as tb->v6_rcv_saddr.s6_addr32[3] and prepending ::ffff: when creating v4 tb2.

Since 429e3d12 ("bonding: Fix extraction of ports from the packet headers"), header offsets used to compute a hash in bond_xmit_hash() are relative to skb->data and not skb->head. If the tail of the header buffer of an skb really needs to be advanced and the operation is successful, the pointer to the data must be returned (and not a pointer to the head of the buffer).

In the cited commit, if the routing device is ovs internal port, the out device is set to uplink, and packets go out after encapsulation. If filter device is uplink, it can trigger the following syndrome: mlx5_core 0000:08:00.0: mlx5_cmd_out_err:803:(pid 3966): SET_FLOW_TABLE_ENTRY(0x936) op_mod(0x0) failed, status bad parameter(0x3), syndrome (0xcdb051), err(-22) Fix this issue by not offloading internal port if filter device is out device. In this case, packets are not forwarded to the root table to be processed, the termination table is used instead to forward them from uplink to uplink.

When mlx5e_xdp_xmit is called without the XDP_XMIT_FLUSH set it is possible that it leaves a mpwqe session open. That is ok during runtime: the session will be closed on the next call to mlx5e_xdp_xmit. But having a mpwqe session still open at XDP sq close time is problematic: the pc counter is not updated before flushing the contents of the xdpi_fifo. This results in leaking page fragments. The fix is to always close the mpwqe session at the end of mlx5e_xdp_xmit, regardless of the XDP_XMIT_FLUSH flag being set or not.

Currently, whenever fw issues a change ownership event, the PF that owns the fw tracer drops its ownership directly and the other PFs try to pick up the ownership via what MTRC register suggests. In some cases, driver releases the ownership of the tracer and reacquires it later on. Whenever the driver releases ownership of the tracer, fw issues a change ownership event. This event can be delayed and come after driver has reacquired ownership of the tracer. Thus the late event will trigger the tracer owner PF to release the ownership again and lead to a scenario where no PF is owning the tracer. To prevent the scenario described above, when handling a change ownership event, do not drop ownership of the tracer directly, instead read the fw MTRC register to retrieve the up-to-date owner of the tracer and set it accordingly in driver level.

With current implementation in single FDB LAG mode all packets are processed by eswitch 0 rules. As such, 'peer' FDB entries receive the packets for rules of other eswitches and are responsible for updating the main entry by sending SWITCHDEV_FDB_ADD_TO_BRIDGE notification from their background update wq task. However, this introduces a race condition when non-zero eswitch instance decides to delete a FDB entry, sends SWITCHDEV_FDB_DEL_TO_BRIDGE notification, but another eswitch's update task refreshes the same entry concurrently while its async delete work is still pending on the workque. In such case another SWITCHDEV_FDB_ADD_TO_BRIDGE event may be generated and entry will remain stuck in FDB marked as 'offloaded' since no more SWITCHDEV_FDB_DEL_TO_BRIDGE notifications are sent for deleting the peer entries. Fix the issue by synchronously marking deleted entries with MLX5_ESW_BRIDGE_FLAG_DELETED flag and skipping them in background update job. Signed-off-by:

Currently, mlx5 is registering event handler for vport context change event some time after arming the event. this can lead to missing an event, which will result in wrong rules in the FDB. Hence, register the event handler before arming the event. This solution is valid since FW is sending vport context change event only on vports which SW armed, and SW arming the vport when enabling it, which is done after the FDB has been created.

The cited patch change mlx5 driver so that during probe DMA operations were performed before pci_enable_device(), and during teardown DMA operations were performed after pci_disable_device(). DMA operations require PCI to be enabled. Hence, The above leads to the following oops in PPC systems[1]. On s390x systems, as reported by Niklas Schnelle, this is a problem because mlx5_pci_init() is where the DMA and coherent mask is set but mlx5_cmd_init() already does a dma_alloc_coherent(). Thus a DMA allocation is done during probe before the correct mask is set. This causes probe to fail initialization of the cmdif SW structs on s390x after that is converted to the common dma-iommu code. This is because on s390x DMA addresses below 4 GiB are reserved on current machines and unlike the old s390x specific DMA API implementation common code enforces DMA masks. Fix it by performing the DMA operations during probe after pci_enable_device() and after the dma mask is set, and during teardown before pci_disable_device().
