This helper function takes a remote IP address, and tries to
determine the dracut command line arguments ip= and ifname= that
will make this remote address reachable during boot.
Functionality was taken from the module-setup.sh scripts of 95iscsi and 95nfs,
cleaned up and fixed some issues in particular with statically configured
networks, where the old code would print the unsupported string
"$ifname:static".
Add support to boot from an NVMe over TCP device.
Example of supported command line formats:
nvme.discover=tcp:192.168.1.3::4420
nvme.discover=tcp:192.168.1.3 # will use 4420 as default svcid
- Create is_nvmf() function to handle all fabrics types
- Fix parse_nvmf_discover() to correctly use the default values
- Auxiliary function to validate an IP connection
- Fix inverted result for getargbool when reading "rd.nonvmf" command line parameter
Requires rd.neednet=1
Requires adding/replacing STARTMODE in /etc/sysconfig/network/ifcfg-ethX to "nfsroot"
to avoid shutdown hanging in initiator

This fixes two issues:
1) on non-x86 systems in non-hostonly config this would cause
an annoying warning on every initramfs generation
2) on non-x86 systems in hostonly config this would result in
early microcode not getting disabled
ipv6 addresses need square brackets, otherwise the iscsi discovery and log-in,
which adds the iscsi port after another colon will get confused and fail.
On Fedora/RHEL, libcryto will verify both itself and libssl on start, if
libssl is missing, FIPS self test will fail. However libssl is not a
dependency of libcryto so dracut will not install it, unless some other
binary or library pulls it in. Systemd requires libssl, so in most cases
it just worked, but could fail in some corner cases where systemd is not
used.

After changing the kernel command line, the cmsifup script calls ifup
to activate the interface. However, ifup is only available in the
network-legacy module; when using the network-manager module, we
should regenerate connections according to the command line; then
later NM will be run and will activate the device.
Most rpc services are not needed for NFSv4, so skip these components
to save space. rpc.idmapd is still needed in case of
nfs4_disable_idmapping is set to 0.
Since commit ff70adf873ef ("initrd: save hostname to a file in /run"),
the initrd generator of NetworkManager parses the hostname from 'ip='
options of the kernel command line and writes it to
/run/NetworkManager/initrd/hostname.
When that file exists, set the kernel hostname.
In presence of multiple hostnames in the command line, the last one
wins. Hostnames from command line always have precedence over ones
received through DHCP. This is a bit different from the legacy network
module that gives higher precedence to the hostname (from DHCP or
command line) of the last interface that is brought up, which depends
on the udev order.
In commit 49c4172 all shell based memory tracing functions are removed,
there are some left over. Remove them as well.

With memstrack module, rd.break may not work because the hook scripts
are sourced, not executed, so the exit call will make pre-pivot queue
exit early. See 98dracut-systemd/dracut-pre-pivot.sh, everything after
"source_hook cleanup" will be ignored.
Replace with return instead.

For the GRUB and zipl bootloaders the BLS fragment that is shipped by the
kernel package is used, so the same fragment is used for the rescue entry.
But there are cases where this BLS fragment is not suitable. For example,
if the boot directory is on a btrfs subvolume the path in the linux and
initrd fiels need to be adjusted with the real path. Otherwise GRUB won't
be able to read them.
The GRUB and zipl kernel-install plugins already take care of this before
installing the BLS fragments, so just copy the installed fragment that has
the updated paths instead of using the BLS shipped by the kernel package.

The first line in crypttab with a "force" option causes all subsequent
lines to be included as if they also had it set because the variable
used to track it is not reset between loop iterations. So fix that by
just setting it to empty before the check for the force option.
If a crypto kernel module changes from compiled in to module, the
encrypted disk might fail to open, because the kernel module was
not included in the initramfs.
This patch tries heuristically to catch such modules.

This feature could be off loaded to memstrack, which have better
accurecy, better performance, and have more detailed tracing features.
Also simplify make_trace_mem a bit.
And currently rd.memdebug=4 is unstable, fails from time to time.
Install libnss_dns.so and libnss_mdns4_minimal.so plugins for the Name
Service Switch (NSS) functionality of glibc so that name resolution
through /etc/resolv.conf and mDNS works in the initrd.
Fixes: #772
