2021-04-08devices: af_packet - use netlink to get/set mtuAloys Augustin1-11/+93
The /sys filesystem is not always accurate when switching network namespaces. Using netlink should work in more situations. Type: improvement Change-Id: I71611f14319820469ea7794eec5b7c6c70e2be6d Signed-off-by: Aloys Augustin <aloaugus@cisco.com>
2020-04-27devices: allow link state down with netlinkMatthew Smith1-1/+1
Type: fix Use the up parameter in vnet_netlink_set_link_state(). It was ignoring the parameter and always setting IFF_UP on an interface. Change-Id: I0d44406d982afbdc43bc6b26d0f22c0bdd47abdc Signed-off-by: Matthew Smith <mgsmith@netgate.com>

2018-03-03netlink: Use nl_pid 0 to play nice with others.Jon Loeliger1-1/+1
While the netlink field is named nl_pid, and typically contains a process id, setting it to a pid value directly prevents other modules from also using a netlink socket. On the other hand, setting it to 0 allows multiple modules to use a netlink socket by letting the kernel assign the nl_pid a value. This allows the verito tap code to interact nicely with the router plugin's librtnl after, say, tap-inject has been enabled.

2017-12-01virtio: fix coverity warningsSteven1-5/+6
Fix 3 coverity warnings 1. api_format.c: init net_ns = 0 and remove its corresponding vec_add and vec_free 2. netlink.c (reported in tap.c before the code was removed): resource leaked due to fd is not close 3. tap.c: subtract 1 for size when calling strncpy to accommodate the terminated NULL character Change-Id: Iff4e66604862f0c06dac227b8cfd48d3979e41a5 Signed-off-by: Steven <sluong@cisco.com>
