Vitaly Kuznetsov 8809883482 hv_netvsc: set nvdev link after populating chn_table ... Crash in netvsc_send() is observed when netvsc device is re-created on mtu change/set channels. The crash is caused by dereferencing of NULL channel pointer which comes from chn_table. The root cause is a mixture of two facts: - we set nvdev pointer in net_device_context in alloc_net_device() before we populate chn_table. - we populate chn_table[0] only. The issue could be papered over by checking channel != NULL in netvsc_send() but populating the whole chn_table and writing the nvdev pointer afterwards seems more appropriate.
