Users can currently pick specific versions of NIC naming, but that
does not guarantee that NIC names won't change after the kernel adds
a new sysfs attribute.
This patch allows for an allow/deny list of sysfs attributes
that could be used when composing the name.
These lists can be supplied as an hwdb entry in the form of
/etc/udev/hwdb.d/50-net-naming-allowlist.hwdb
net:naming:drvirtio_net
ID_NET_NAME_ALLOW=0
ID_NET_NAME_ALLOW_ACPI_INDEX=1
ID_NET_NAME_ALLOW_ADDR_ASSIGN_TYPE=1
ID_NET_NAME_ALLOW_ADDRESS=1
ID_NET_NAME_ALLOW_ARI_ENABLED=1
ID_NET_NAME_ALLOW_DEV_PORT=1
ID_NET_NAME_ALLOW_FUNCTION_ID=1
ID_NET_NAME_ALLOW_IFLINK=1
ID_NET_NAME_ALLOW_INDEX=1
ID_NET_NAME_ALLOW_LABEL=1
ID_NET_NAME_ALLOW_PHYS_PORT_NAME=1
ID_NET_NAME_ALLOW_TYPE=1
We already refuse the other two cursor-related options (--cursor= and
--after-cursor=) with --since=, so let's do the same with
--cursor-file=.
Closes: #20523
Regardless of whether a vc path is passed, the behavior of
systemd-vconsole-setup wasn't ideal when either the passed vc or /dev/tty1 was
in graphics mode.
When a vc in graphics mode was passed, no message was emitted despite the fact
that the font settings couldn't be applied. The previous code might have
assumed that setfont(8) would throw a warning but that's not case.
When no argument was passed, systemd-vconsole-setup was supposed to
automatically select a valid tty, init it and copy the font setting to the
remaining ttys. However if the selected virtual console was in KD_GRAPHICS mode
the initialization of the font failed not only for the selected source vc but
for all of them.
This patch enables IFNAME_VALID_ALTERNATIVE for checks guarding the
parsing of RestrictNetworkInterfaces=.
The underlying implementation for this option already supports
altnames.
