rename iface_has_link() to iface_has_carrier() to clarify usage
Only assign static "wildcard interface" settings, if the interface has a
carrier.
If the interface name was specified with a name, do not do carrier
checking for static configurations.
all_ifaces_up() is true, if all interfaces are up.
all_ifaces_setup() is true, if all interfaces are up and the gateways
and nameserver are setup.

If this option is set, dracut will try to connect via dhcp
<cnt> times before failing. Default is 1.

If this option is set, dhclient is called with "-timeout <arg>".
rd.net.timeout.iflink=<seconds>
Wait <seconds> until link shows up. Default is 60 seconds.
rd.net.timeout.ifup=<seconds>
Wait <seconds> until link has state "UP". Default is 20 seconds.

Wait <seconds> until route shows up. Default is 20 seconds.
rd.net.timeout.ipv6dad=<seconds>
Wait <seconds> until IPv6 DAD is finished. Default is 50 seconds.
rd.net.timeout.ipv6auto=<seconds>
Wait <seconds> until IPv6 automatic addresses are assigned.
Default is 40 seconds.
rd.net.timeout.carrier=<seconds>
Wait <seconds> until carrier is recognized. Default is 5 seconds.

Some hosting providers need a static route set in order to be
able to reach the default gateway. Be sure to retry adding
the default gateway after setting the static routes.
For targets with colons in the iSCSI target name:
"iqn.2000-09.com.foo:storage-system.e2000:00000001cm1p1"
the parser was confused with the optional iscsi_iface_name and
iscsi_netdev_name.
This patch reintroduces the old IQN, EUI and NAA parsing and enhances
the fallback parser by checking the LUN for a numerical value.
In the judgment sentence, it will print the following warning message,
becasuse of lacking the blank on the left of ']'.

When installing OS to a VLAN enabled iscsi LUN (extracted from iBFT), "/tmp/net.{xyz}.has_ibft_config" is not being set properly.
Then anaconda installer requires 'BOOTPROTO="ibft"' populated in ifcfg of the vlan interface (ex: ibft0.20), for it to properly populate the kernel parameters post installation. The setting 'BOOTPROTO="ibft"' is populated by write-ifcfg.sh script only if the corresponding interface has a file /tmp/net.{xyz}.has_inft_config
To get around this issue, in ibft_to_cmdline() function in net-lib.sh file, I made the following changes to populate the has_ibft_config file for the vlan interface(ex: ibft0.20):
By convention, strstr should be a literal string match. Previously, it
would match as a glob pattern. Some code used that, so add new
functions strglob and strglobin to do what that code expects, and
specify them tightly too. strglob tests whether the glob pattern
matches the entire string (the name strglob is also used in the yorick
language, and that's what it does there), while strglobin tests whether
the glob pattern matches anywhere in the string.
Also tightens str_starts, str_ends, and str_replace to deal with
literal strings only. In a quick grep I did not find code that depended
on these functions matching globs.
Changes the call sites where strstr was used with glob patterns to use
strglobin or strglob as the intention seemed to be (or, in one case,
strstr with the * removed as it did not affect the result anyway).
Fix 3 issues in ibft_to_cmdline():
- unset local variables at the beginning of each loop
- only write vlan.conf when we write out ip=xxx
- when vlan id is 0, don't write out vlan.conf. Because 0 means untagged
and we don't actually need vlan interface.
configured_ifaces is a function that returns the names of each interface
that the user wanted configured.
Currently, this is accomplished by reading the list from
/tmp/net.ifaces. But if we want to allow the user to specify an
interface by its MAC address or IP or something, we need a function that
will read the cache and convert the MACs etc. to names.
(Obviously this conversion only works once udev starts, so it will warn
you if you try it too early.)
Now that we can use a MAC as a device identifier, we can just bring up
the device specified by BOOTIF as a normal interface.
So instead of ignoring everything but BOOTIF, we'll put BOOTIF in the
IFACES list and bring it up as normal, defaulting to DHCP if nothing
else is specified.
We can also handle anaconda-style 'ksdevice=bootif' this way.
