6c5c5f7e55 libseckey: Adapt keymgmt_match() implementation to OpenSSL
OpenSSL commit ee22a3741e3fc27c981e7f7e9bcb8d3342b0c65a changed the
OpenSSL provider's keymgmt_match() function to be not so strict with
the selector bits in regards to matching different key parts.

Adapt the secure key provider's match function accordingly.
This means, that if the public key is selected to be matched, and
the public key matches (together with any also selected parameters),
then the private key is no longer checked, although it may also be
selected to be matched. This is according to how the OpenSSL function
EVP_PKEY_eq() is supposed to behave.

OpenSSL function SSL_CTX_use_PrivateKey() calls the providers match
function to check if the private key specified matches the public key
of the certificate using EVP_PKEY_eq(). EVP_PKEY_eq() includes the
private key into the selector bits here, although the certificate
only contains the public key part.

d7b1cbad8b cpumf/pai: Add Processor Activity Instrumentation tool
The Processor Activity Instrumentation facility (PAI) uses the
perf_event_open system call to report data and the crypto counter
values. The data can be inspected with the perf tool in a very
generic way using raw data report and a hex dump utility.

The pai tool also uses the perf_event_open system call to record the
data, but uses specialized event attributes for recording detailed
information such as the recording of fork, exit, exec system call
events and context switch events.
Cryptography counter values are appended as raw data attachments.

The pai command can be used for recording and reporting.
Also a list of CPUs can be specified.
The recording ring buffers are created per CPU
and are named paicrypto.XXX where XXX stands for the CPU number.
The numbering scheme has leading zeros, such as 007 for CPU number 7.

For invocation and possible command line options see the man page.

c4e4b926b4 zdump/dfi: Fix segfault due to double free
The problem can happen when dfi_s390mv_init_gen() returns with an error
code to dfi_init() in dfi.c.
Double free condition occurs on zg_close() call at the end of the
while loop in dfi_init() if zg_close() has already been called for the
same file handle at the end of open_dump() function in scope of
dfi_s390mv_init_gen() processing.
This global file handle is not closed during init() call for any
other dump formats. Since it is not reopened/reused after open_dump() call
during multi-volume dump initialization, we should not close it at all.

The problem can be reproduced in the following steps:

1) Install multi-volume dump tool

   # zipl -M mvdump.conf
   Dump target: 2 partitions with a total size of 4732 MB.
   Warning: All information on the following partitions will be lost!
      /dev/dasdb2
      /dev/dasdb3
   Do you want to continue creating multi-volume dump partitions (y/n)?y
   Done.

2) Run zgetdump -i using device (not partition) as a parameter without
   taking actual dump.

   # zgetdump -i /dev/dasdb
   free(): double free detected in tcache 2
   Aborted (core dumped)

6324f62da7 zpcictl: Add option to trigger firmware reset
With "zpcictl --reset DDDD:BB:FF.F" now causing a fully Linux driven
reset where the Linux kernel does an explicit device driver unbind,
disable and re-enable, let's also expose a way to instead have firmware
perform a device reset by issuing an SCLP with SCLP_ERRNOTIFY_RESET.

When firmware is done resetting the device it will then issue an error
notification with PCI Error Code 0x3a indicating successful reset, which
will subsequently cause the new kernel based automatic recovery
mechanism to perform recovery in coordination with the device driver.
This allows resetting devices without unbinding them from their device
driver and thus without losing related block devices or network
interfaces. This may also be used to test the automatic recovery
mechanism.

3ade063ea2 zpcictl: Fix race of SCLP reset and Linux recovery
Currently "zpcictl --reset DDDD:BB:FF.F" issues an SCLP call with
SCLP_ERRNOTIFY_AQ_RESET followed by a Linux driven device reset via the
recover sysfs attribute. The latter was introduced with commit
bc0d40c580 ("zpcictl: Initiate recover after reset") because the
firmware driven reset leaves the device in the error state. Now with the
addition of transparent PCI recovery however the situation has changed
as Linux will not leave the device in the error state after the reset
but will instead initiate its automatic recovery flow. With that however
the two mechanisms, automatic PCI recovery and the zpcictl triggered
recovery attribute handler will race against each other.

In practice this is harmless as the automatic recovery is serialized
with the recover attribute and whichever wins the race will do the reset.
The losing side will detect that the original device was removed and
will refrain from causing a double reset.

Letting both mechanisms race against each other is not predictable
behavior though so instead of SCLP_ERRNOTIFY_AQ_RESET issue
a SCLP_ERRNOTIFY_AQ_REPORT_ERROR that will report a device error to the
Support Element but not cause a reset and then predictably reset via the
recover sysfs attribute. If instead a firmware driven reset followed by
the automatic recovery flow is desired the new "--reset-fw" option may
be used.

673ff375d9 genprotimg/check_hostkeydoc: relax default issuer check
While the original default issuer's organizationalUnitName (OU)
was defined as "IBM Z Host Key Signing Service", any OU ending
with "Key Signing Service" is considered legal.

Let's relax the default issuer check by stripping off characters
preceding "Key Signing Service".

4e2ebe0370 libseckey: Fix re-enciphering of EP11 secure key
The re-enciphering of EP11 asymmetric secure keys does not work.
First, the result of the re-encipher operation of the private key
part must be copied back into the user supplied key token buffer.
Second, the public key part, i.e. the MACed SubjectPublicKeyInfo
(SPKI) structure must also be re-enciphered (i.e. re-MACed), since
the MAC is calculated with the EP11 master key.

78b053326c genprotimg: remove DigiCert root CA pinning
Remove the DigiCert root CA pinning. The root CA used for the chain of trust can
change in the future therefore let's remove this check. If someone wants to
enforce the usage of a specific root CA it can be selected by the genprotimg
command line option `--root-ca $CA`. Make it transparent to the user which root
CA is actually being used by printing the subject name of the root CA to stdout
in verbose mode.

ab06a5d88a cpictl: Handle excessive kernel version numbers
Some development kernel versions provide an 8-digit date number like
"20220325" in place of the second kernel sublevel, while the data
format used to send this information to the HMC only supports 16 Bit
numbers. As a result, the HMC displays a seemingly random sublevel
number.

Fix this by replacing excessive sublevel numbers with 0 to ensure that
these numbers are handled consistently.

a0a71efde0 fdasd: Fix endless menu loop on EOF
Hitting CTRL-D anywhere will cause fdasd to go into an endless loop
displaying the main menu over and over again. Killing fdasd (e.g.
via CTR-C) is the only way out.
The issue is that read_line() is just ignoring the resulting EOF
condition on stdin. Subsequent invocations of read_line() will return
immediately and thus cause the loop. A simple fix is to reset stdin
after EOF. A caller of read_line() will see the same behavior as for
EOL with no input.

This can now include /lib/modprobe.d/10-unsupported-modules.conf

Strictly speaking, modprobe would only consider *.conf files inside

do the same for the added missing locations.

a28b396d9e zipl: make IPL sections defined with BLS to inherit a target field
The target field is required for IPL sections, but the ones populated from
BLS snippets did not have this field. This was only working when using BLS
snippets because IPL sections inherit the target field with "defaultauto".

But that's not the case when using a menu, for example the following zipl
configuration will fail if it's used along with BLS defined IPL sections:
fail when running the zipl tool:

  [defaultboot]
  defaultmenu = menu1

  :menu1
  target = /boot
  1 = linux
  2 = test
  default = 1
  prompt = 1
  timeout = 0

Because "linux" and "test" will be defined using BLS snippets and these
don't have an option to define target fields. Let's make these to always
inherit a target field, either from the [defaultboot] section or a menu
section if there's a defaultmenu defined.

ae7217806b common.mak: remove LINK and LINKXX
Now that we've concluded that the compiler is used for calling the actual
linker, it doesn't make much sense to select a different compiler for linking.
Even worse, it's prone to error. A naive user might try to compile s390-tools
using clang as follows:

  $ make -C genprotimg CC=clang
  ...
  CC      genprotimg/src/utils/curl.o
  LINK    genprotimg/src/genprotimg
  /usr/bin/ld: genprotimg.o: `stderr@@GLIBC_2.2' non-PLT reloc for symbol defined in shared library and accessed from executable (rebuild file with -fPIC ?)
  /usr/bin/ld: final link failed: bad value
  collect2: error: ld returned 1 exit status

Therefore it makes sense to use the same compiler for linking as well.
