      hv_netvsc: fix a race between netvsc_send() and netvsc_init_buf() · e8f0a89c
      Vitaly Kuznetsov 提交于
      Fix in commit 88098834 ("hv_netvsc: set nvdev link after populating
      chn_table") turns out to be incomplete. A crash in
      netvsc_get_next_send_section() is observed on mtu change when the device
      is under load. The race I identified is: if we get to netvsc_send() after
      we set net_device_ctx->nvdev link in netvsc_device_add() but before we
      finish netvsc_connect_vsp()->netvsc_init_buf() send_section_map is not
      allocated and we crash. Unfortunately we can't set net_device_ctx->nvdev
      link after the netvsc_init_buf() call as during the negotiation we need
      to receive packets and on the receive path we check for it. It would
      probably be possible to split nvdev into a pair of nvdev_in and nvdev_out
      links and check them accordingly in get_outbound_net_device()/
      get_inbound_net_device() but this looks like an overkill.
      
      Check that send_section_map is allocated in netvsc_send().

      firewire-net:
      - set min/max_mtu
      - remove fwnet_change_mtu
      
      nes:
      - set max_mtu
      - clean up nes_netdev_change_mtu
      
      xpnet:

      hippi:

      - remove hippi_change_mtu
      
      batman-adv:
      - set max_mtu
      - remove batadv_interface_change_mtu
      - initialization is a little async, not 100% certain that max_mtu is set
        in the optimal place, don't have hardware to test with
      
      rionet:
      - set min/max_mtu
      - remove rionet_change_mtu
      
      slip:
      - set min/max_mtu
      - streamline sl_change_mtu
      
      um/net_kern:
      - remove pointless ndo_change_mtu
      
      hsi/clients/ssi_protocol:
      - use core MTU range checking
      - remove now redundant ssip_pn_set_mtu
      
      ipoib:
      - set a default max MTU value
      - Note: ipoib's actual max MTU can vary, depending on if the device is in
        connected mode or not, so we'll just set the max_mtu value to the max
        possible, and let the ndo_change_mtu function continue to validate any new
        MTU change requests with checks for CM or not. Note that ipoib has no
        min_mtu set, and thus, the network core's mtu > 0 check is the only lower
        bounds here.
      
      mptlan:
      - use net core MTU range checking
      - remove now redundant mpt_lan_change_mtu
      
      fddi:
      - min_mtu = 21, max_mtu = 4470
      - remove now redundant fddi_change_mtu (including export)
      
      fjes:
      - min_mtu = 8192, max_mtu = 65536
      - The max_mtu value is actually one over IP_MAX_MTU here, but the idea is to
        get past the core net MTU range checks so fjes_change_mtu can validate a
        new MTU against what it supports (see fjes_support_mtu in fjes_hw.c)
      
      hsr:
      - min_mtu = 0 (calls ether_setup, max_mtu is 1500)
      
      f_phonet:
      - min_mtu = 6, max_mtu = 65541
      
      u_ether:

      phonet/pep-gprs:
      - min_mtu = 576, max_mtu = 65530
      - remove redundant gprs_set_mtu
