* this is needed for python3-ifcfg to parse it correctly https://github.com/ftao/python-ifcfg/issues/43 * backport this single patch, so it can be backported to dunfell then for master we should upgrade to new snapshot from debian which includes other fixes and improvements as well * this is already part of net-tools_1.60-26.diff from debian we're using but it's first added there and then removed $ grep 'sprintf(flags' net-tools_1.60-26.diff ++ sprintf(flags, "flags=%d<", ptr->flags); +- sprintf(flags, "flags=%d<", ptr->flags); * before: root@qemux86-64:~# ifconfig eth0 Link encap:Ethernet HWaddr 52:54:00:12:34:02 inet addr:192.168.7.2 Bcast:192.168.7.255 Mask:255.255.255.0 inet6 addr: fe80::5054:ff:fe12:3402/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:6 errors:0 dropped:0 overruns:0 frame:0 TX packets:106 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:496 (496.0 B) TX bytes:42832 (41.8 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:846 errors:0 dropped:0 overruns:0 frame:0 TX packets:846 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:53364 (52.1 KiB) TX bytes:53364 (52.1 KiB) * after: root@qemux86-64:~# ifconfig eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 metric 1 inet 192.168.7.2 netmask 255.255.255.0 broadcast 192.168.7.255 inet6 fe80::5054:ff:fe12:3402 prefixlen 64 scopeid 0x20<link> ether 52:54:00:12:34:02 txqueuelen 1000 (Ethernet) RX packets 6 bytes 496 (496.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 14 bytes 2140 (2.0 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 metric 1 inet 127.0.0.1 netmask 255.0.0.0 inet6 ::1 prefixlen 128 scopeid 0x10<host> loop txqueuelen 1000 (Local Loopback) RX packets 80 bytes 6080 (5.9 KiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 80 bytes 6080 (5.9 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 * for comparison ubuntu-20.04 in docker: root@dafcbbf25ff2:/# ifconfig eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 172.17.0.2 netmask 255.255.0.0 broadcast 172.17.255.255 ether 02:42:ac:11:00:02 txqueuelen 0 (Ethernet) RX packets 39299 bytes 89614740 (89.6 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 33767 bytes 3807354 (3.8 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536 inet 127.0.0.1 netmask 255.0.0.0 loop txqueuelen 1000 (Local Loopback) RX packets 5658 bytes 1294220 (1.2 MB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 5658 bytes 1294220 (1.2 MB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 * python3-ifcfg now parses flags correctly: root@qemux86-64:~# python3 -m ifcfg.cli | python3 -m json.tool { "eth0": { "inet": "192.168.7.2", "inet4": [ "192.168.7.2" ], "ether": "52:54:00:12:34:02", "inet6": [ "fe80::5054:ff:fe12:3402" ], "netmask": "255.255.255.0", "device": "eth0", "flags": "4163<UP,BROADCAST,RUNNING,MULTICAST> ", "mtu": "1500", "broadcast": "192.168.7.255" }, "lo": { "inet": "127.0.0.1", "inet4": [ "127.0.0.1" ], "ether": null, "inet6": [ "::1" ], "netmask": "255.0.0.0", "device": "lo", "flags": "73<UP,LOOPBACK,RUNNING> ", "mtu": "65536" }, "sit0": { "inet": null, "inet4": [], "ether": null, "inet6": [], "netmask": null, "device": "sit0", "flags": "128<NOARP> ", "mtu": "1480" } } (From OE-Core rev: dacfd695061b186240a85f8ffc43e6636c56e1fb) Signed-off-by: Martin Jansa <Martin.Jansa@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
