Fix the igb PTP support to explicitly reject any future flags that get added to the external timestamp request ioctl. In order to maintain currently functioning code, this patch accepts all three current flags. This is because the PTP_RISING_EDGE and PTP_FALLING_EDGE flags have unclear semantics and each driver seems to have interpreted them slightly differently.

Commit 823eb2a3 ("PTP: add support for one-shot output") introduced a new flag for the PTP periodic output request ioctl. This flag is not currently supported by any driver. Fix all drivers which implement the periodic output request ioctl to explicitly reject any request with flags they do not understand. This ensures that the driver does not accidentally misinterpret the PTP_PEROUT_ONE_SHOT flag, or any new flag introduced in the future. This is important for forward compatibility: if a new flag is introduced, the driver should reject requests to enable the flag until the driver has actually been modified to support the flag in question.

mlxsw does not support VXLAN devices with a physical device attached and vetoes such configurations upon enslavement to an offloaded bridge. Commit 0ce1822c ("vxlan: add adjacent link to limit depth level") changed the VXLAN device to be an upper of the physical device which causes mlxsw to veto the creation of the VXLAN device with "Unknown upper device type". This is OK as this configuration is not supported, but it prevents us from testing bad flows involving the enslavement of VXLAN devices with a physical device to a bridge, regardless if the physical device is an mlxsw netdev or not. Adjust the test to use a dummy device as a physical device instead of a mlxsw netdev. Fixes: 0ce1822c ("vxlan: add adjacent link to limit depth level") Signed-off-by:

Previously, hns3 driver just directly send specific setting bit and mask bits of MAC VLAN switch parameter to the firmware, it can not be compatible with the old firmware, because the old one ignores mask bits and covers all bits with new setting bits. So when running with old firmware, the communication between PF and VF will fail after resetting or configuring spoof check, since they will do the MAC VLAN switch parameter configuration. This patch fixes this problem by reading switch parameter firstly, then just modifies the corresponding bit and sends it to firmware.

j1939_session_destroy() and __j1939_priv_release() should be called only if session, ecu or socket are not linked or used by any one else. If at least one of these resources is linked, then the reference counting is broken somewhere. This warning will be triggered before KASAN will do, and will make it easier to debug initial issue.

An ESP packet could be decrypted in async mode if the input handler for this packet returns -EINPROGRESS in xfrm_input(). At this moment the device reference in skb is held. Later xfrm_input() will be invoked again to resume the processing. If the transform state is still valid it would continue to release the device reference and there won't be a problem; however if the transform state is not valid when async resumption happens, the packet will be dropped while the device reference is still being held. When the device is deleted for some reason and the reference to this device is not properly released, the kernel will keep logging like: unregister_netdevice: waiting for ppp2 to become free. Usage count = 1 The issue is observed when running IPsec traffic over a PPPoE device based on a bridge interface. By terminating the PPPoE connection on the server end for multiple times, the PPPoE device on the client side will eventually get stuck on the above warning message. This patch will check the async mode first and continue to release device reference in async resumption, before it is dropped due to invalid state. v2: Do not assign address family from outer_mode in the transform if the state is invalid v3: Release device reference in the error path instead of jumping to resume Fixes: 4ce3dbe3 ("xfrm: Fix xfrm_input() to verify state is valid when (encap_type < 0)") Signed-off-by:

I2C communication errors (-EREMOTEIO) during the IRQ handler of nxp-nci result in a NULL pointer dereference at the moment: BUG: kernel NULL pointer dereference, address: 0000000000000000 Oops: 0002 [#1] PREEMPT SMP NOPTI CPU: 1 PID: 355 Comm: irq/137-nxp-nci Not tainted 5.4.0-rc6 #1 RIP: 0010:skb_queue_tail+0x25/0x50 Call Trace: nci_recv_frame+0x36/0x90 [nci] nxp_nci_i2c_irq_thread_fn+0xd1/0x285 [nxp_nci_i2c] ? preempt_count_add+0x68/0xa0 ? irq_forced_thread_fn+0x80/0x80 irq_thread_fn+0x20/0x60 irq_thread+0xee/0x180 ? wake_threads_waitq+0x30/0x30 kthread+0xfb/0x130 ? irq_thread_check_affinity+0xd0/0xd0 ? kthread_park+0x90/0x90 ret_from_fork+0x1f/0x40 Afterward the kernel must be rebooted to work properly again. This happens because it attempts to call nci_recv_frame() with skb == NULL. However, unlike nxp_nci_fw_recv_frame(), nci_recv_frame() does not have any NULL checks for skb, causing the NULL pointer dereference. Change the code to call only nxp_nci_fw_recv_frame() in case of an error. Make sure to log it so it is obvious that a communication error occurred. The error above then becomes: nxp-nci_i2c i2c-NXP1001:00: NFC: Read failed with error -121 nci: __nci_request: wait_for_completion_interruptible_timeout failed 0 nxp-nci_i2c i2c-NXP1001:00: NFC: Read failed with error -121 Fixes: 6be88670 ("NFC: nxp-nci_i2c: Add I2C support to NXP NCI driver") Signed-off-by:Stephan Gerhold <stephan@gerhold.net> Reviewed-by:
