Bug description:
[impact]
if link is already up, configured mac isn't set
this also affects the master/nomaster configuration
[test case]
create .network config for the link, for example:
[Match]
Name=eth0
[Link]
MACAddress=00:16:3e:ff:ff:ff
[Network]
DHCP=yes
make sure the link is already up, and restart systemd-networkd:
root@test-f:/etc/systemd/network# ip l show eth0
61: eth0@if62: <BROADCAST,MULTICAST> mtu 1500 qdisc noqueue state DOWN mode
DEFAULT group default qlen 1000
link/ether 00:16:3e:fc:b2:00 brd ff:ff:ff:ff:ff:ff link-netnsid 0
root@test-f:/etc/systemd/network# ip l set dev eth0 up
root@test-f:/etc/systemd/network# ip l show eth0
61: eth0@if62: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state
UP mode DEFAULT group default qlen 1000
link/ether 00:16:3e:fc:b2:00 brd ff:ff:ff:ff:ff:ff link-netnsid 0
root@test-f:/etc/systemd/network# systemctl restart systemd-networkd
root@test-f:/etc/systemd/network# ip l show eth0
61: eth0@if62: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state
UP mode DEFAULT group default qlen 1000
link/ether 00:16:3e:fc:b2:00 brd ff:ff:ff:ff:ff:ff link-netnsid 0
root@test-f:/etc/systemd/network# ip l set dev eth0 down
root@test-f:/etc/systemd/network# ip l show eth0
61: eth0@if62: <BROADCAST,MULTICAST> mtu 1500 qdisc noqueue state DOWN mode
DEFAULT group default qlen 1000
link/ether 00:16:3e:fc:b2:00 brd ff:ff:ff:ff:ff:ff link-netnsid 0
root@test-f:/etc/systemd/network# systemctl restart systemd-networkd
root@test-f:/etc/systemd/network# ip l show eth0
61: eth0@if62: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state
UP mode DEFAULT group default qlen 1000
link/ether 00:16:3e:ff:ff:ff brd ff:ff:ff:ff:ff:ff link-netnsid 0
[regression potential]
any regression would likely result in incorrectly set link mac and/or
master, or failure to correctly set mac and/or master
[scope]
this is needed for g and earlier
this is fixed upstream by commit
e16e4b3bedc57919b3ecb4096e941709a5d39b8a which is included in v247 so
this is fixed already in h and later
[other info]
this moves the configuration of the link mac and master out of the
link_up() function, so this also allows repeated calls to link_up()
without reconfiguring the link mac and master. That behavior is useful
for the commits for bug 1664844
