f5744b95db genprotimg: Fix build with OpenSSL 1.1
OpenSSL 1.1 seems to use a non-const parameter to X509_name_dup(), but
x509_armonk_locality_fixup() is passing a const there. The compile then
fails on "discards 'const' qualifier", when -Werror is used. Thus
resolve with a type-cast like in c2b_name().

90a2e6d70e zipl/src: Fix leak of files
Fix leak of temporary files: if prepare_build_program_table_file()
is called in no dry-run mode and there was an error then the file
@filename will not be deleted in free_bootloader()).

Fix leak of renamed files as well as corruption of previously
created bootmap files with the same name in case of unsuccessful
IPL installation.

Add a special flag to keep a track of file's "temporary" state;
Base the cleanup decision on this flag instead of checking dry-run;
Release resources captured by prepare_bootloader() in the error path;
Move the final rename to be called only after successful installation.

                    Original logic:

prepare_bootloader_ipl():
prepare_bootloader_ngdump():

  always create temporary @filename
  if (!dry-run) rename @filename;
  install;
  cleanup: if (dry_run) drop @filename (*** LEAK ***)

prepare_bootloader_device():

  if (dry_run) create temporary @filename
  install, don't rename;
  cleanup: if (dry_run) drop @filename

                    New logic:

prepare_bootloader_ipl():
prepare_bootloader_ngdump():

  always create temporary @filename and set @tmp_filename_created;
  install;
  if (!dry_run) rename @filename and clear @tmp_filename_created;
  cleanup: if (@tmp_filename_created is set), drop @filename

prepare_bootloader_device():

  if (dry_run) create @filename and set @tmp_filename_created;
  install, don't rename;
  cleanup: if (@tmp_filename_created is set) drop @filename.

'Poughkeepsie' as issuer locality are still considered as valid as long
as they are signed with the IBM signing keys private key. In addition,
drop the check for 'issuer(HKD) == subject(HKSK)' as it doesn't improve
security. While at it, remove now unused functions and fix a memory leak

7dc2513205 zkey: Detect FIPS mode and generate PBKDF for luksFormat according to it
For LUKS2 volumes, zkey generates 'cryptsetup luksFormat' commands with
options '--pbkdf argon2i --pbkdf-memory 32 --pbkdf-force-iterations 4'
for low memory and time requirements. Using the default Argon2i options
might cause out-of-memory errors when multiple encrypted volumes are
unlocked automatically at boot through /etc/crypttab.

When the system runs in FIPS mode, which is indicated by file
/proc/sys/crypto/fips_enabled containing '1', the Argon2i password based
key derivation function might be disabled by a policy, and such
'cryptsetup luksFormat' commands might fail.

Generate '--pbkdf pbkdf2' instead if the system runs in FIPS mode.

0748d365a6 genprotimg/**/Makefile: Fix staged installs
Fix the support for staged installs. The Makefile variable `PKGDATADIR`
uses `DESTDIR` for all Makefile target, but actually it should only be
used for the `install*` and `uninstall*` targets. [1] Fix this by using
`DESTDIR` only for `install*` targets - uninstall* targets are not
supported by s390-tools.

Before this change, if `DESTDIR` was set for staged installs,
`genprotimg` has tried to find the bootloader binaries at the temporary
installation path `$DESTDIR$(TOOLS_DATADIR)/genprotimg/` instead of
`$(TOOLS_DATADIR)/genprotimg`.

Unsigned, Signed(EcSECP521R1, Rsa(2048, 3072))

As the user-data enum was not marked as non-exaustive this might be a
breaking change for users. (Not for any crate in this repo though).

The addition of such user-data is provided by following patches.

e40a3e0621 pvapconfig/tests: use a temporary directory for tests
Use the `TemporaryDirectory` type to create a temporary directory. This
type has the advantage that the directory is automatically removed once
it goes out of scope. The old implementation in test_sysfs_write_i32
leaks a directory if a previous subtest failed. Also, using a temporary
directory for the LockFile test fixes the following error:

  $ RUST_BACKTRACE=1 cargo test -- helper::tests::test_lockfile

Recent changes makes it reasonable to update the version string of pv
and pv_base to 1.0.0. Recent changes introduced some non-backwards
compatible changes, like move some Error definition from pv to the new
pv_core crate. Also, the pv crates seem to be in a good shape to be
considered released.

Therefore, move up the Semver to 1.0.0.
See also:
https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html

NOTE: As these crates are not published to `crates.io` as of now, the
version number is meaningless, as cargo will not pull them from

c0a12b29d0 rust/pv: Reorganize some tests
Use a static Mockito server instead of creating multiple on-the-fly

verifier API test to the test folder as it tests the public API. Also,
make the Debug impl for CertVerifier public. The test relocation
requires this. Before, there could be a test local implementation of the
Debug impl as it was in the same crate.

While at it, get rid of the lazy_static crate in favor of the once_cell
crate. As the new std lib implementation is very near to the one from
once cell. The project will switch to the std impl when v1.70 is
available in all supported distros. See:

9b51b8b882 rust/pv: Refactor pv crate
Big refactoring patch of the pv crate. The main reason behind this
refactoring is to simplify testing and maintaining the pv crate while
keeping OpenSSL/libcurl dependencies optional. Using crate features
increases the number of targets that have to be tested. This refactoring
eliminates the use of features by splitting the functionality of pv into
a use OpenSSL and no-use-OpenSSL crate.

Split off some code from the pv crate into a pv_core crate. pv requires
pv_core and reexports all symbols. pv_base contains all code from former
pv that does not use OpenSSL or libcurl functionalities. The refactored
pv crate contains functionalities to generate requests and validate host
key documents. All features from pv are dropped as they are not needed
anymore and to streamline the codebase for easier use and testing. While
at it fix some documentation issues.

Users (pvsecret & pvapconfig) have next to no code change, besides the
different import of the crate.

b5f7ac95d8 cpuplugd: adjust to CPU 0 being no longer hotpluggable
With kernel commit 496bb034f4ff ("s390/smp: disallow CPU hotplug
of CPU 0") it is no longer possible to hotplug CPU 0.

As a side effect, the sysfs handle /sys/devices/system/cpu/cpu0/online
does no longer exist. Since cpuplugd relies on checking all online
handles of all CPUs, this change causes cpuplugd to fail as it
interprets a non existing online file as an indicator that no other CPUs
with higher IDs exist as well. This leads to cpuplugd assuming that
there are no CPUs available.

Instead of checking for the online file, it is preferable to check for
the existence of the parent folder to verify the existence of a CPU.
As a consequence, all other checks for non-existing online files must
now imply that the CPU is online, but not hotpluggable.

bc4f455151 zdev/dracut: retain early persistent config over switch root
Useful for debugging (what happened during early boot).

Also useful for distro installers, which can import the early config into
their own environment early after starting:
chzdev --import /run/zdev.initrd.config --persistent --yes \
       --no-root-update --force --verbose

After that, distro installers can modify/add the device config based
on interactive or unattended installation choices using
chzdev --enable --active --persistent ...

Finally, distro installers can likewise transfer the entire device config
to the installed system mounted under $SYSROOT:
chzdev --export /tmp/zdev.config --all --type --persistent --verbose

[59-dasd.rules] into initrd for the same functionality like 95dasd or
95dasd_rules.

9b2fb1d4d2 zdev: add helper to convert from dasd_mod.dasd to zdev config
Shell library, which can be sourced by other POSIX compatible shell
scripts. Provide helper function parsing its stdin based on the syntax of
kernel device driver parameter dasd_mod.dasd= and invoking chzdev to
produce corresponding persistent device configurations. The helper function
takes one argument, which is either "globals" or "ranges". For a complete
configuration, call the function twice, first with "globals" and then with
"ranges".

The new script library file should be packaged in a core (sub)package of
s390-tools so the script is available for initrd environments.

Users with examples:

Subsequent commit ("zdev/dracut: add rd.dasd parsing") introduces
zdev/dracut/95zdev/parse-dasd.sh performing:
zdev_parse_rd_dasd | zdev_parse_dasd_list globals 2>&1 | zdev_vinfo
zdev_parse_rd_dasd | zdev_parse_dasd_list ranges 2>&1 | zdev_vinfo

https://github.com/dracutdevs/dracut/pull/2534 updates
modules.d/80cms/cmssetup.sh performing:
echo "$DASD" | zdev_parse_dasd_list globals 2>&1 | vinfo
echo "$DASD" | zdev_parse_dasd_list ranges 2>&1 | vinfo

The parsing code for rd.dasd using the same syntax as dasd_mod.dasd=
is inspired by the own implementation that used to be in linuxrc.s390
of https://github.com/rhinstaller/anaconda.

ed106d7f28 zdev/dracut: add site support for early devices to the kdump case
The existing code can already determine the required devices for the
actively running system, but this does not work for execution environments
in different (disaster recovery) sites.

Kdump likely does not notice when running in a different site and does not
re-generate the kdump initrd (because the kdump config itself does not
change).

The new code allows users to explicitly specify devices required for early
boot in initrd on different sites. Assuming this is a small number of
devices and could even overlap between the root-fs and the kdump case, do
not further distinguish those two sets of devices, but simply use the same
marker attribute "zdev:early=1" for both cases. With all this site
information available at the (initial) kdump initrd generation, the
resulting kdump initrd can work on any site without having to re-generate.

Complements commit 3c7adcc3c81d ("zdev: dracut: modifiy the
module-setup.sh").

63f31bf73e zdev/dracut: add field debugging capabilities with logging
Additional debugging output can be generated with e.g. dracut option
"--stdlog 5" (or short -L5). It shows the chzdev export result, the output
of chzdev imports, and an overview of the resulting persistent config
within the initrd.
On systems, which default to using dracut option "--quiet", you might need
an additional "--verbose" to counter "--quiet" so -L5 has effect.
Typically combined with "--debug" to get a shell trace from building an
initrd (Note: --debug does not increase the log levels).

7bec672c7e zdev/dracut: fix kernel module install even for hostonly mode
Otherwise, dracut skips modules that are "not hostonly", i.e. not used /
loaded on the system when running dracut to build an initrd.
Without the fix, zdev device auto configuration only works for device
types for which a device driver happened to be loaded when building an
initrd. Likewise for specifying rd.* boot options.

Hostonly mode is often the default in Linux distributions.
Make zdev device auto configuration work nonetheless without users
having to know about and tweak dracut modes for initrd generation.

On the typical sloppy hostonly mode, the code disables hostonly for
installing kernel modules. This covers building regular initrds, where zdev
device auto configuration should even work for device types, for which
device drivers were not loaded when an initrd was generated. This can
happen when new devices of new types are configured for a DPM logical
partition. Also, users could want to start using dracut cmdline options
rd.{dasd,zfcp,znet} for a device type that was not used when the initrd was
built.

The special strict hostonly mode is used by some kdump implementations. In
that case, hostonly remains in effect intentionally because only support
for the really required devices as determined by dracut module 95zdev-kdump
should be included in a kdump initrd due to the memory-constrained kdump
environment. Cf. commit 73c46a3056 ("zdev/dracut: fix kdump by only
activating required devices"), which also provides more references on
strict hostonly mode. Even for non-kdump cases, let strict hostonly mode be
effective here in 95zdev in case some future use case appears for this
special mode beyond kdump.

55fdb17b18 ap_tools/ap-check: handle get-attributes between pre and post event
Since mdevctl commit acf78c1ff6c9 it is now possible for the
get-attributes event to occur between a pre-define and post-define.
This is done in order to obtain the active attributes for the device
before writing them to the config file, and implies that the
get-attributes cannot re-obtain the file lock.  For other cases
where mdevctl calls get-attributes, the file lock is not already
held and must be obtained by ap-check before reading attributes from
active devices.
To solve this, let's use the knowledge that mdevctl is a single-threaded
tool and add a test to detect this scenario.  If the file lock is
already held by the parent during a get-attributes, don't attempt to
re-acquire it.

Make sure that the kernel command line used for the Secure Execution
boot image is always null-terminated. Before this change, users had to
ensure that the provided kernel cmdline was null-terminated, which was
error-prone. But since the default s390x Linux kernel command line is
set to `root=/dev/ram0 ro` the remaining reserved memory for the kernel
command line is zeroed out. Therefore, the problem only shows up if the
used kernel command line is shorter than the default kernel command
line.

  $ uname -r

  $ cat /sys/firmware/cpi/system_level

  --reboot--

  $ uname -r
  5.4.256
  $ cat /sys/firmware/cpi/system_level
  0x4260000000504100

The first sublevel field is defined as one byte, so ensure that
a value larger than that isn't included.

90475fbaa5 common.mak: use eval only once for defining variables
Using eval only once at the top most function "define_toolchain_variables",
makes the other subsequent eval calls redundant.

“The result of the eval function is always the empty string; thus, it
can be placed virtually anywhere in a makefile without causing syntax
errors.” [1]

So this patch also prevents potential syntax errors using GNU Make <v4.2.
Since version 4.2 GNU Make introduced a less errorness function calling and
variable expanding with commit
e971597 ("[SV 46995] Strip leading/trailing space from variable names")

07ff9e1da0 zdev: limit the derivation of ZDEV_SITE_ID
Currently ZDEV_SITE_ID is derived with the help of an additional
udev-rule, 40-zdev-id.rules. The sole purpose of this rule is to
determine the ZDEV_SITE_ID environment value with the help of zdev_id
binary. This solution is minimal, but this has some unwanted side-
effects. The zdev_id logic get executed for all the events, even
those completely unrelated to zdev/or site, and imports the unneeded
envionment values to the udev-db.

Instead of having an additional rule file, add this logic as part of
the udev-rule of those devices which are configured with site-support.
The logic will then be available on all those rules with the
site-supported devices only.

6d06921276 zdev:qeth: adapt performance_stats attribute semantics
Behaviour of the qeth performance_stats sysfs attribute has changed
with kernel commit
b0abc4f5df76 ("s390/qeth: overhaul ethtool statistics")
that went into kernel v5.1.

Before the kernel commit
- collection of statistics was turned on and off by writing 1 or 0
- default after device activation was 0
- statistics were reset by writing 0

After the kernel commit:
- collection is always on
- attribute always reads 1
- statistics is reset by writing 1; writing 0 is a no-op

Problems of chzdev on new kernels:
chzdev cannot reset statistics ('performance_stats=1' does nothing).
'chzdev --export' always lists performance_stats.
'chzdev qeth --help-attribute performance_stats' reflects old behaviour.

This patch will do the following:
'chzdev qeth --help-attribute performance_stats' reflects new behaviour.
'chzdev --export' does not list performance_stats on new kernels.
'chzdev performance_stats=1' resets statistics on new kernels.
'chzdev performance_stats=0' still resets statistics on old kernels,
    does nothing on new kernels.

Excluding them from being collected from sysfs saves hundreds times

271b809495 zdump/dfi_s390: Support reading compressed s390_ext dumps
Update dfi_s390.c to support reading of compressed dump segments.
For this, introduce a callback function for reading memory chunks
associated with compressed dump segments. Apart from the segment location
on disk this function requires the entry_offset array from the dump segment
header in order to process each compressed entry separately, thus allowing
fast seek processing for zgetdump (no need to decompress a big dump segment
to extract a single piece of data).

In addition, split mem_chunks_add_ext() in several functions.

With current implementation, printing progress while writing a compressed

skip progress_print() in write_addr_range() and call it after each

write_addr_range() to call progress_print() conditionally based on the new
print_progress parameter.

For non-compressed dump segments, call progress_print() from
write_addr_range() just as before.

d53bfb9201 zipl/boot: Integrate zlib compression to single volume DASD dumper
Integrate zlib DFLTCC deflate compression to single volume dasd dumper
using the existing s390 extended dump format. Compression takes place
only if DFLTCC facility is available, otherwise dump is written
uncompressed as before.

First megabyte of memory is always written uncompressed and afterwards
this area is used for zlib workspace and for the compression output buffer.
The compression takes place in chunks of data of equal size (currently 1MB)
and the offset of each compressed chunk is stored in the dump segment
header. Since existing dump segment headers of 1 page size are used, we
need to limit the maximum size of compressed dump segments.
Chunk is written uncompressed in case of compression error or if
deflate compression only makes it bigger.

Thus every chunk of data is compressed separately and can be decompressed
independently. The main reason for that is to enable zgetdump to make fast
read seeks. Otherwise, zgetdump would need to decompress a big dump segment
in the worst case to extract a single piece of data.

Put compression related functions and structures to eckd2dump_zlib.c
and eckd2dump_zlib.h

Update zipl man page with the general information of zlib compression
support.

1b044b8a40 zkey: Support EP11 AES keys with prepended header to retain EP11 session
The pkey kernel module supports two key blob formats for EP11 AES keys.
The first one (PKEY_TYPE_EP11) contains a 16 bytes header that overlays
the first 32 bytes of the key blob which usually contain the ID of the
EP11 session to which the key is bound. For zkey/dm-crypt that session
ID used to be all zeros. The second blob format (PKEY_TYPE_EP11_AES)
prepends the 16 bytes header to the blob, an thus does not overlay the
blob. This format can be used for key blobs that are session-bound, i.e.
have a non-zero session ID in the first 32 bytes.

Change zkey to generate EP11 keys using the new format (i.e. pkey type
PKEY_TYPE_EP11_AES), but existing key blobs using the old format can
still be used.

4b486e87cc zdev/dracut: fix kdump build to integrate with site support
This complements v2.27.0 commit 73c46a3056 ("zdev/dracut: fix kdump by
only activating required devices"). On older distributions, the absence of
zdev_id can cause the following harmless error messages for each udev
event:

(spawn)[387]: failed to execute '/lib/s390-tools/zdev_id' \
'/lib/s390-tools/zdev_id': No such file or directory

Kdump is still functional nonetheless.

As of v2.24.0 commit 2e89722ef0 ("zdev: make site specific udev-rule for
ccw"), the invocations of chzdev within
zdev/dracut/95zdev-kdump/module-setup.sh generate
/etc/udev/rules.d/40-zdev-id.rules. And so even though zdev-kdump
intentionally does not install zdev_id and its previous singular user
zdev/udev/81-dpm.rules into the kdump initrd, because DPM device auto
configuration is not desired in the kdump environment, zdev_id meanwhile
has an additional functionality for site-support and the generated
40-zdev-id.rules calls /lib/s390-tools/zdev_id. By installing zdev_id into
the kdump initrd, 40-zdev-id.rules can work without error.

e6add997eb Integrate rust into s390-tools build system
The rust integration into the s390-tools build system consists of the
following steps:

- Add a subdirectory for the rust code.
- Add a Makefile that forwards rust builds to `cargo`.
- Add a `utils` crate for rust code in s390-tools.
- Add rust stuff for dotfiles:
  - gitignore
  - editorconfig
  - codespellrc (while at it, add an ignore file)

With cargo the rust ecosystem has its own build system which also is
responsible to resolve rust dependencies via downloading the dependencies
from (default) crates.io and discover the source files. Therefore, the
Makefile just calls `cargo build` to forward the build to cargo.

If a rust crate does not require external dependencies, users might call
rustc directly.

A simple `make` will build all the rust targets as well (with --release
specified). Also `make install` will work as usual.

A few Makefile configuration variables are introduced for rust/Cargo:
  - HAVE_CARGO (default 1) to toggle the build of rust code using cargo
  - CARGOFLAGS             to add custom cargo flags, e.g. --offline
  - CARGO		   Cargo binary location defaults to
                           $(where cargo)

A new global make target is defined to get the current s390-tools
version:
$ make version
  2.28.0

rust/Makefile also has the `print-rust-targets`  target to print all rust
directories/crates that should be shipped/installed.

a500946e50 vmur: fix wrong command flag exclusion
Command vmur issues a warning and aborts receiving a file from

Example:
 ./vmur re -t 0x25,0x40 22 -H /tmp/xxx.txt
 vmur: Conflicting options: -b and -t are mutually exclusive.
This is wrong as there is only one option specified.
The command should be aborted only when both flags are specified.

Fix this wrong behavior.

5a848c98bb zipl/src: remove no-pie and noexecstack compiler and linker flags
Only the bootloaders cannot be built as PIE and for that there are
already the -no-pie linker and compiler flags set by the boot/Makefile.
In addition, remove the `noexecstack` linker flag as it has no use
anymore (see commit 518bf7d7357 ("zipl/boot: use
`--no-warn-rwx-segments` linker flag")). It was originally introduced to
declare the ELF segment of the bootloader stack as non-executable. But
this ELF attribute had no effect for multiple reasons:

1. ALL_LDFLAGS is not used for the bootloaders
2. no ELF loader is used for the bootloaders that would take this ELF
   attribute into account

This fixes the problem of overriding  `-fPIE` set by the distributor.

7e53611e3a dump2tar: fix truncated paths
When creating a tar archive, dump2tar incorrectly truncates the last
character of file paths that are exactly 100 characters long.

Paths up to 100 characters can be represented in the 100-byte name field
of a tar header entry, while longer paths are handled via an additional
tar data block. For 100-character paths, dump2tar determines that a
single header is sufficient, but then uses util_strlcpy() to store the
path into the name field. Since util_strlcpy() ensures nul-terminated
strings, the final character of the path is overwritten.

Fix this by using strncpy() instead of util_strlcpy(). Also mark the
affected name fields as "nonstring" to prevent associated compiler
warnings.

4d4ddbd887 Recursive Makefiles: avoid race condition in the install target
The `install` Makefile target of the top Makefile has `all` and
`install-recursive` as prerequisites. This leads to the two recursive
Makefile calls `make -C <SUBDIR> all` and `make -C <SUBDIR> install`.

The problem is these two targets try to build the same object files and
this leads to a race condition between these two targets in case of a
parallel build.

Fix this problem by removing the `all` prerequisite from the `install`
target, as it is not needed since all the `install` targets in the
sub-Makefiles already have proper prerequisites.

By using core utilization, thread utilization, and management
utilization, it is possible to determine how much capacity is left or
how much the real CPU SMT utilization is on lpars. Extending hyptop
with this new field provides useful information.

For more info about real CPU SMT utilization:
https://linux.mainframe.blog/smt_utilization/

Briefly:
ur = real SMT util
uc = core util
ut = thread util
um = *management util
s  = **speedup factor

	ur = ((uc * per_core_thr_count) - ut) / s + (ut - uc) + um

* management utilization:
logical core time spent on hypervisor instead of logical partition.
** speedup factor:
metric used to calculate the SMT utilization on that logical core. This
value varies depending on the workload and the machine generation due
to hardware optimization level.

de013d2f04 Makefile: add genprotimg to non-s390x architectures target list
`genprotimg` can be useful on non-s390x architectures such as x86 or
arm. Therefore add `genprotimg` to the non-s390x target list.

How to build genprotimg on a non-s390x system (s390x cross-compiler
required)

$ # Build and install /usr/bin/genprotimg
$ make -C genprotimg
$ make install -C genprotimg
$ # Build and install the genprotimg bootloaders
$ make -C genprotimg/boot HOST_ARCH=s390x CROSS_COMPILE=s390x-linux-gnu-
$ make install -C genprotimg/boot HOST_ARCH=s390x CROSS_COMPILE=s390x-linux-gnu-

ed94cf9839 genprotimg/boot: compile the bootloaders only if HOST_ARCH is s390x
The genprotimg bootloaders are s390x specific, so only build them if the
`HOST_ARCH' is set to s390x.

On x86 one can cross-compile and install the bootloaders as follows:

$ make -C genprotimg/boot HOST_ARCH=s390x CROSS_COMPILE=s390x-linux-gnu-
$ make -C genprotimg/boot install HOST_ARCH=s390x CROSS_COMPILE=s390x-linux-gnu-

Under typical circumstances these sysfs attributes should be available
however if the device happens to be in the process of being removed
without the protection of the ap config file lock, this scenario can
be encountered.  In this case, ignore the device and assume it is in
the process of being removed.

dad7fce7a1 zipl/boot: move load_wait_psw() location
`load_wait_psw` is defined in include/boot/s390.h but is implemented in
zipl/boot/libc.c. This results in a dangling definition for s390.h users
other than zipl, due to the missing implementation. Since the function
is only relevant for zipl, move the definition to the corresponding
header file zipl/boot/libc.h

8058921f58 Reorganize boot-loader header files
include/boot/s390.h relies on s390 specific kernel headers. However,
some tools used this header for non-s390 code (outside of boot-loaders).
To solve this the PSW and PAGE_SIZE definitions are now in separate
header files. All includes for s390.h which are not in boot-loader code
are replaced with one of psw.h or page.h.

This fixes the compilation failure on ppc64le due to conflicting types
for `__vector128`.

other selection options --by-path and --by-interface which both return
the more appropriate exit code 3 (EXIT_DEVICE_NOT_FOUND).

6028300366 cpacfstatsd: don't fail if no crypto counters are supported
Do not fail to start the daemon if no crypto counters are supported, as
there is still a use case for the daemon to run, as the user can then
use the 'cpacfstats' tool to evaluate that no counter stats are
available. Previously, the user had to check the syslogs for the reason
why the daemon was not running and the cpacfstats command failed.

Before this change:

$ cpacfstats
cpacfstats: Can't access domain socket file '/run/cpacfstatsd_socket', errno=2 [No such file or directory]
cpacfstats: Maybe cpacfstatsd daemon is not running ???
cpacfstats: Can't connect to daemon

After this change:

$ cpacfstats
 des counter: unsupported
 aes counter: unsupported
 sha counter: unsupported
 rng counter: unsupported
 ecc counter: unsupported
 pai_user   : unsupported
 pai_kernel : unsupported

Also, it's no good practice to let systemd services fail, because
otherwise the system state will be shown as 'degraded':

$ systemctl status
* a46lp59
    State: degraded
     Jobs: 0 queued
   Failed: 1 units

$ systemctl list-units --failed

09c01e580a zdev: use rename-file to avoid any symlinks created
During the boot, the ZDEV_SITE_ID is derived with the help
of loadparm and will be saved in ZDEV_SITE_ID_FILE, which
will be the used by the udev-rules.

ZDEV_SITE_ID_FILE creation can have a surface of symlink attack
as we are directly using the fopen and fprintf on it. To avoid
this, make sure that we are writing the ZDEV_SITE_ID to a temporary
file, which will then be renamed to ZDEV_SITE_ID_FILE, which will
remove all the existing symlinks associated with the target file.

Tip: you may skip the pvsecret build by adding
`HAVE_OPENSSL=0`, `HAVE_LIBCURL=0`, or `HAVE_CARGO=0`.
The runtime requirements are: openssl-libs (>= 1.1.1).

- Packages: blktrace, multipath-tools, sg3-utils
- Tools: rsync, tar, lsscsi
* zipl
For CCW-type DASD dump, zlib compression can be used to compress the dump
data before writing it to the DASD partition. It can benefit from
s390 on-chip compression accelerator (DFLTCC) and provide a faster dumping
process, hence lower system downtime.
The zlib version integrated with zipl (zipl/boot/zlib) is based on the Linux
kernel zlib (kernel version 6.3) which represents zlib version 1.1.3 with a
limited number of functions and a number of updates on top including s390
hardware compression (DFLTCC) support. Also, all memory allocations are
performed in advance, which aligns with zipl requirements.
The CCW-type standalone dumper is built as a single binary and must be
loaded to stage2 during boot. Hence, all required zlib functions must be
integrated into it, and its size is restricted. To limit the size, only
deflate-related parts are integrated (no decompression is required during
dumping).
Removing the inflate modules and function prototypes are the only major
modifications made to the kernel version of zlib.
* zgetdump
For building zgetdump you need OpenSSL version 1.1.0 or newer
installed (openssl-devel.rpm). Also required is glib2
