Date: Tue, 22 Sep 2020 01:53:18 +0200 From: Jan Engelhardt <jengelh@...i.de> To: stephen@...workplumber.org Cc: netdev@...r.kernel.org Subject: [PATCH iproute2] ip: do not exit if RTM_GETNSID failed `ip addr` when run under qemu-user-riscv64, fails. This likely is due to qemu-5.1 not doing translation of RTM_GETNSID calls. 2: host0@if5: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 5a:44:da:1a:c4:0b brd ff:ff:ff:ff:ff:ff request send failed: Operation not supported Treat the situation similar to an absence of procfs.
