      Calvin Owens 提交于
      This implements ndo_poll_controller in net_device_ops callbacks for mlx5,
      which is necessary to use netconsole with this driver.

      tg3: Avoid NULL pointer dereference in tg3_io_error_detected() · 1b0ff898
      Milton Miller 提交于
      While the driver is probing the adapter, an error may occur before the
      netdev structure is allocated and attached to pci_dev. In this case,
      not only netdev isn't available, but the tg3 private structure is also
      not available as it is just math from the NULL pointer, so dereferences
      must be skipped.
      
      The following trace is seen when the error is triggered:

      This patch avoids the NULL pointer dereference by moving the access after
      the netdev NULL pointer check on tg3_io_error_detected(). Also, we add a
      check for netdev being NULL on tg3_io_resume() [suggested by Michael Chan].

      nfp: bpf: improve handling for disabled BPF syscall · b47c62c5
      Arnd Bergmann 提交于
      I stumbled over a new warning during randconfig testing,
      with CONFIG_BPF_SYSCALL disabled:
      
      drivers/net/ethernet/netronome/nfp/nfp_net_offload.c: In function 'nfp_net_bpf_offload':
      drivers/net/ethernet/netronome/nfp/nfp_net_offload.c:263:3: error: '*((void *)&res+4)' may be used uninitialized in this function [-Werror=maybe-uninitialized]
      drivers/net/ethernet/netronome/nfp/nfp_net_offload.c:263:3: error: 'res.n_instr' may be used uninitialized in this function [-Werror=maybe-uninitialized]
      
      As far as I can tell, this is a false positive caused by the compiler
      getting confused about a function that is partially inlined, but it's
      easy to avoid while improving the code:
      
      The nfp_bpf_jit() stub helper for that configuration is unusual as it
      is defined in a header file but not marked 'static inline'. By moving
      the compile-time check into the caller using the IS_ENABLED() macro,
      we can remove that stub and simplify the nfp_net_bpf_offload_prepare()
      function enough to unconfuse the compiler.
