Subject: [dpdk-dev] [PATCH 2/2] kni: fix build for 5.0 for igb_ndo_bridge_setlink()
Date: Tue, 22 Jan 2019 15:44:29 +0000	[thread overview]
Message-ID: <20190122154429.41882-2-ferruh.yigit@intel.com> (raw)
In-Reply-To: <20190122154429.41882-1-ferruh.yigit@intel.com>

Build error seen with Linux kernel 5.0 and
when CONFIG_RTE_KNI_KMOD_ETHTOOL is enabled.

build error:
.../build/build/kernel/linux/kni/igb_main.c:2348:24:
  error: initialization of
  ‘int (*)(struct net_device *, struct nlmsghdr *, u16,
  	struct netlink_ext_ack *)’
  {aka ‘int (*)(struct net_device *, struct nlmsghdr *,
  	short unsigned int,  struct netlink_ext_ack *)’}
  from incompatible pointer type
  ‘int (*)(struct net_device *, struct nlmsghdr *, u16)’
  {aka ‘int (*)(struct net_device *, struct nlmsghdr *,
  	short unsigned int)’}
  [-Werror=incompatible-pointer-types]
  .ndo_bridge_setlink = igb_ndo_bridge_setlink,
                        ^~~~~~~~~~~~~~~~~~~~~~
.../build/build/kernel/linux/kni/igb_main.c:2348:24:
  note: (near initialization for ‘igb_netdev_ops.ndo_bridge_setlink’)

igb_ndo_bridge_setlink() is changed in Linux kernel version 5.0
and now requires a new parameter, 'struct netlink_ext_ack *extack'.
Fixed by adding a new parameter with a kernel version check.
