This should be no problem (if OpenSSL works correctly), because
`crls_download_cb` is only called out of the verification context of
OpenSSL. It's used to look up a CRL and therefore
X509_STORE_CTX_get_current_cert should always return a certificate
since X509_STORE_CTX_get_current_cert returns NULL only if an error
has occurred during the verification (see
https://www.openssl.org/docs/man1.1.0/man3/X509_STORE_CTX_get_current_cert.html).

Add host-key document verification support to genprotimg. This ensures

certificate (signed by the root CA used) so a chain of trust starting

By default, genprotimg tries to download all revocation lists needed
by looking up in the corresponding certificate on how CRL information

Modern systems have systemd manage system mount points like sysfs which
specify 'sysfs' as a keyword for the device as there is no device
associated with this special filesystem. However, any arbitrary string
could be specified here and the determination of the sysfs mount point
would fail in such a case.
To make sure that the mount point of the sysfs is still found when
mounted with a device keyword specified other than 'sysfs', check for
the filesystem type instead, which is more specific.

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 using zgetdump on a multi-volume device dump, the sysfs path to

$ zgetdump -i /dev/dasdb1
zgetdump: Could not open "/sys/bus/ccw/devices/0.0.9300/dasdb/dev" (No

A simple fix would be to add the missing "block" part in the sysfs path.
However, the logic still assumes sysfs links like "block:" that have
been deprecated a decade ago and are no longer present on modern
systems anyway.
Therefore, the logic can greatly be improved. Create a separate function
to determine whether a device is online, remove the logic for "block:"
entries, and use libutil functions to reduce the complexity even further.

The ERRMSG_EXIT macro is a bit clunky in its usage and a change is
necessary in order to free memory in error cases.
Create a new function error() that takes only a format string and adds
all other relevant information by itself. This function frees memory
before terminating the program with the EXIT_FAILURE exit code.
This simplifies the error handling for pretty much all calls and makes
the code a bit cleaner.
While at it, the defines EXIT_MISUSE and EXIT_BUSY don't provide any
value. Neither are they documented nor are these standardized. Also, a
parent process is mostly interessted in success or failure only anyway.
Replace these by using only EXIT_FAILURE in the error() function.
Also, change multiline output to a combination of warnx and error to
have a uniformed output. So this:
WARNING: Device is formatted with a different blocksize (4096).
Use --mode=full to perform a clean format.
becomes this:
dasdfmt: WARNING: Device is formatted with a different blocksize (4096).

When calling dasdfmt on device node symlinks like
/dev/disk/by-id/ccw-0X9300, dasdfmt fails with "dasdfmt: the ioctl to get
the blocksize of the device failed (Bad file descriptor)"
This is because before the actual formatting process starts, the disk
will be disabled calling the BIODASDDISABLE ioctl, resulting in the
removal of the symlink. Trying to open this file later in the process to
retrieve e.g. blocksize information results in the mentioned error, as
the file doesn't exist any longer.
This incorrect behaviour was introduced with commit 8826028bdc
("dasdfmt: Use libdasd provided ioctl functions") at which the use of a
globally available file descriptor was omitted. Instead, the ioctl
library functions require a device node to be passed as a function
parameter and will open a file descriptor themselves.
So, before that change, the global file descriptor was always valid even
when the file was removed.
In order to fix this without modifying the behaviour of libdasd,
introduce the two global variables dev_node and dev_path. dev_path is
the original device path entered by the user. dev_node on the other hand
is the reliable device node under /dev/block/ using the major and minor
numbers and is determined in get_device_name().
The dev_path is used for message output only and the dev_node variable
is used for the actual disk operations.
As these two variables are global, the device parameters for several
functions are removed to make the code a bit cleaner.
