Deleting an HSCI interface, the connected HiperSockets interface's name
and the connected Ethernet interface's name are extracted from "ip link
show". Currently the extracted names are directly used in "bridge -d link
show dev ifname" for further checking. If "iflink" and "ifindex" of an
interface are not matched, ip commands will print @ifXX appended to the
real interface's name. Thus, it will be failed if the interface's name
with the ending @ifXX is used in "bridge -d link show dev ifname" for
further checking.
To solve the problem, the ending @ifXX must be removed before the
interface name is used further.

In the current code, after the function check_pnetids() and the function
verify_precon() are called, $? from each function is used twice
successively. It is used for the first time in the condition of the IF
statement, while for the second time as return code of the current
function. In bash, $? can be used to get the return code, but only for
the first time directly after the previous function is called.
Afterwards, $? will be reset to "0". Thus, the right return code can not
be get, if $? is used second time.
To solve the problem, using $? for the second time should be avoided.

When keys are generated concurrently in EKMF Web from multiple clients,
and the key labels use a sequence number tag, then the assignment logic
of the sequence number may cause a duplicate sequence number to be used,
because another key might have already been generated with the same
sequence number, since the next-to-use sequence number has been retrieved
from EKMF Web. This results in a HTTP response code of 409 and a -EEXIST
return code from ekmf_generate_key().
Instead of getting the last used sequence number from EKMFWeb, tell
EKMFWeb to automatically use the next available sequence number when
generating a key. When the sequence number label tag value is 'next'
then EKMFWeb will automatically assign the next available sequence number
to the label tag and increment the sequence number in an atomic way.

If a memory chunk is added to mem_phys as well as mem_virt
in dfi_mem_chunk_add_vol() then an illegal memory access might occur
when accessing mem_chunk->data e.g. in dfi_elf_mem_chunk_read_fn()
because the data block pointed to by the data field is now being referenced
by two memory chunks, one in mem_phys and one in mem_virt. If it happens
that the memory chunk from mem_virt is freed in mem_unmap() then
the memory chunk in mem_phys still points to the common data block
which has been already freed. This leads to all sort of bad behavior
in dfi_elf_mem_chunk_read_fn() and other places where mem_chunk->data
might be accessed.

Some Linux distributions always include a copy of all persistent device
configuration data when updating the initial RAM-disk. This makes
chzdev's persistent device configuration changes ineffective because
device configuration directives applied in the RAM-disk take precedence
over those stored in the root filesystem.
This patch introduces a new build-time switch which allows distributions
to specify that whenever there is a persistent device configuration
change, the RAM-disk is updated automatically.
This feature can be enabled by adding 'ZDEV_ALWAYS_UPDATE_INITRD=1' as
a zdev build option. Where, by default ZDEV_ALWAYS_UPDATE_INITRD is 0.

Extend zkey to allow to store a (dummy) LUKS2 passphrase together with a
secure key, for use with LUKS2 volumes. That way, when the repository is
backed up, or archived, also the passphrases of the associated LUKS2
volumes are backed up, or archived, and thus can not be forgotten.
This passphrase is then used in generated commands to format and open
the LUKS2 volumes.
Because of the use of secure keys to encrypt the volumes, the LUKS2
passphrase is of no or less relevance for security. It is therefore OK to
store the passphrase in clear text in the key repository, and also use
them in /etc/crypttab. Therefore, the passphrase could actually be a
trivial passphrase, or a dummy passphrase.
Note: Such a dummy passphrase is NOT considered a secret that needs to
be protected. If for a certain usage the passphrase is of relevance for
security, then the zkey dummy passphrase option must not be used to store
the passphrase.

Adding one to the pointer per block value results in a wrong
calculation of pointer block levels. When writing a file that
would result in about 454MB size, the code would calculate that
it needs a two level pointer directory but correct would be a three
level pointer directory. This causes an invalid filesystem state:
besides missing all the records of one top level pointer directory
entry, it would also record a higher record number in the FST than
what is present in the pointer blocks.
Note that this bug only hits when the file is about 454MB and the write
is stopped (means the file is closed) - if file writing continues the
problem doesn't happen because at some point in time cmsfs-fuse would
switch to three levels of pointer blocks anyways as the file grows.

When specifying an incorrect program option, dasdfmt segfaults as the
format string for the corresponding error message has no parameter.
Add the missing parameter to fix this.
