This patch series extends the s390 qemu CPACF support to be able to
run a subset of the CPACF instruction cross platform. There have been
requests on the kernel crypto mailing list about a way to test
s390 specific crypto implementations. For example a way to test
s390 CPACF exploitation code like the s390_aes.ko kernel module.
So here now is a set of patches verified on x86 and s390 which
over (slow but working) support for a subset of the subfunctions of
some of the CPACF instructions.
Test: There are some very basic tests included with this patch series
suitable for some CI run. Better test coverage can be done by running
a full blown Linux and use for example the in-kernel crypto modules.
The 'usual' in-kernel crpyto modules will be automatically loaded
which run a bunch of test cases. So there is now support for these
kernel modules:
* sha256_s390x (autoloaded, sha256)
* sha512_s390x (autoloaded, sha512)
* aes_s390x (autoloaded, clear key aes ecb, cbc, ctr, xts)
* pkey_pckmo (autoloaded, derive AES protected key from clear key)
* paes_s390x (not autoloaded, protected key aes ecb, cbc, ctr, xts)
All these modules run selftests if configured by the kernel (which is
enabled by default). Failures are reported via syslog. Additionally
the aes testcases from libica can be run either inside such an qemu
environment or with a static build executed with the qemu tcg
application qemu-s390x --cpu max <static-build-libica-test>.
Changelog:
v1: Initial version with
- Related code restructured
- Support KIMD SHA512 and thus SHA256
- Support KMC AES-128, AES-192 and AES-256 and thus have basic AES
support (ECB mode) enabled.
- Support PCC Compute-XTS-Parameter-AES-128 and
Compute-XTS-Parameter-AES-256 but only for block sequence number
0. This is a requirement for the next step:
- Support KM XTS-AES-128 and KM XTS-AES-256. Together with the
minimal PCC support this enables AES-XTS CPACF acceleration.
v2: - Basic PCKMO support to be able to 'derive' an AES protected key
from clear key. See header details.
- Support protected key AES-ECB.
- Support protected key AES-CBC.
- Minimal protected key AES-XTS support for CPACF PCC.
- Support protected key AES-XTS.
- Support AES-CTR.
- Support protected key AES-CTR.
v3: - Reordered patches as suggested by Finn.
- One small bug fix in CPACF_aes.c related to address translation.
v4: - Rename of the parameters based on feedback from Janosch to
make clear these are registers or ptrs to registers.
Added Tested by from Holger. Fixed typo "face" -> "fake".
v5: - Add documentation file docs/system/s390x/cpacf.rst which
describes the state of the CPACF instructions and which
functions are covered when this series is applied.
First version sent to public mailing list qemu-s390x.
v6: - Rebase/rework to build on current qemu head.
- Add docs/system/s390x/cpacf.rst to target-s390x.rst
- New file crypto/aes-helpers.c with some simple
functions to support AES modes CBC, CTR and XTS.
- Slight rewrite of the s390x CPACF implementations to
use these generic AES mode implementations.
v7: - Update on docs/system/s390x/cpacf.rst to mention
the zArchicteture Principles of Operation document
which describes all these CPACF instructions.
v8: - Add a fix which deals with incorrect address handling
in the sha512 implementation related to fetch and push
data from/to memory.
- Slight rework around the capcf function implementation and
exception generation.
- Added some more details to the new cpacf.rst file.
- Fixed some typos and added some suggestions from Finn.
- Fixed cc handling on return of PCKMO (must not update cc).
Missing: simple test cases to verify that the implemented and not
implemented cpacf functions and subfunctions work as expected. But
see the statement about tests at the header.
v9: - Add simple tests for all the implemented CPACF instructions but
pckmo (which is a privileged instruction).
- Reworked the Fix for wrong address to call the wrap function
inline; rephrased commit header.
- Improve the header file cpacf.h to hold defines for all the
cpacf instruction functions and use them in the code.
- one new commit comprising the base protected key support with
exposing the xor pattern and wkvp and en/decrypt key functions
via cpacf.h. So the testcases can use this header file.
- one new commit which reworks the fetch memory and store memory
from and to guest (suggested by Ilya Leoshkevich).
v10: - Fixed v9 patch 3 (cpacf_sha512.c was missing)
Please note that patch #10 "target/s390x: Base support for cpacf
protected keys" produces a build warning ("unused function"). As
by default the qemu build has warnings=errors enabled, this one
patch does not build on it's own. If this is not acceptable, the
hunk introducing the two functions may be moved to the next
commit; another solution would be to merge with patch #11.
v11: Fixed nearly all checkpatch findings - only the warnings about
Maintainers may need update is still there.
v12: - Very first patch is integrated in master and thus removed from
this series.
- New header file include/crypto/aes-headers.h as suggested by
Daniel. Moved the patch which introduces the aes helpers before
the actual AES cpacf implementations and reworked all the code
to use these helpers.
- Merged together "Base support for cpacf protected keys" and
"Support pckmo encrypt AES subfunctions" to fix the broken
build caused by unused functions.
- Merged the changes from patch "Improve fetch and store mem from
and to guest" directly into the code where it is introduced.
v13: - reworked the helper functions to copy memory from and to
guest. These are now inline functions located in
target/s390x/tcg/crypto_helper.h and have been renamed and
extended for u32 and u64 as well. Also the both sha
implementations have been reworked to use these helper
functions. See patch #4 for details.
- fixed the wrong list of parameters docu in patch #5
- added some Reviewed-by tags.
- reworked the testcases to run (more or less) on real s390
hardware. However this does not and can not work with protected
keys.
- rebased to current master head.
v14: - fixed one wrong constant in target/s390x/tcg/cpacf.h
- added 1 patch (patch #1) which fixes the missing privileged
flag with the PCKMO instruction.
- added a simple testcase for the PCKMO instruction (see
tests/s390x/tcg/cpacf-pckmo.c for details).
v15: - rebased to current master
- new patch reworking the addressing mode check in the both
sha256 and sha512 implementations. Also added early bail out.
- In a similar way rework the checking for addressing mode in
cpacf_aes.c (comes in with each algo implementation).
- bail out early on length zero for the cpacf aes algs.
- As suggested by Ilya splitted the cpacf.h into two header
files cpacf-arch.h and cpacf.h.

The CPACF instruction PCKMO is a privileged instruction. So set the
IF_PRIV flag in insn-data.h.inc to reflect this.

Fix missing parts for MSA 9 kdsa and rework the cpacf handling code
so that further extensions can be made in a clean and structured way.
Introduce a new header file cpacf-arch.h to hold defines, structs and
function prototypes around s390 cpacf. Use the cpcaf function defines
in the existing code.

fcallies, cohuck
Move the cpacf sha512 implementation into a new file
cpacf_sha512.c. Add this new file to the build. Introduce a new header
file cpacf.h which holds function prototypes and other things around
cpacf local to the tcg directory.

From: Harald Freudenberger @ 2026-08-18 16:18 UTC (permalink / raw)
To: richard.henderson, iii, david, thuth, berrange
Cc: qemu-s390x, qemu-devel, linux-s390, dengler, borntraeger,
fcallies, cohuck
Add some simple helper functions to copy memory from guest to a local
buffer and the other way around:
- read_guest_wrap_u8()
- write_guest_wrap_u8()
- read_guest_wrap_u32()
- write_guest_wrap_u32()
- read_guest_wrap_u64()
- write_guest_wrap_u64()
The reader functions read from guest memory into an array of
u8/u32/u64 with BE conversion. Similar the writer functions write an
array of u8/u32/u64 into guest memory with BE conversion.
All these functions are intended to be used for the crypto
implementations thus are located in crypto_helper.h.
Rework and simplify the sha 256 and sha 512 implementations to use
these helper functions.

The handling for different addressing modes in the both sha
implementations cpacf sha256 and sha512 was incomplete. Rework this
addressing checking to clearly have support for s390 64 bit and 32 bit
addressing mode but raise an exception otherwise.

Add a new file crypto/aes-helpers.c with simple functions
to support some AES modes:
- AES cbc: AES_cbc_encrypt() AES_cbc_decrypt()
- AES ctr: AES_ctr_encrypt()
- AES xts: AES_xts_encrypt() AES_xts_decrypt()
and some AES related helpers:
- AES_xor()
- AES_xts_prep_next_tweak()
Add header file include/crypto/aes-helpers.h for these functions

Support CPACF pcc subfunctions PCC-Compute-XTS-Parameter-AES-128
and PCC-Compute-XTS-Parameter-AES-245 but only for the special
case block sequential number is 0. However, this covers the s390
AES XTS implementation in the Linux kernel and Libica and thus
also Opencryptoki clear key via Libica.

Cc: qemu-s390x, qemu-devel, linux-s390, dengler, borntraeger,
fcallies, cohuck
Add base support for cpacf protected key handling.
Add support for the pckmo subfunctions PCKMO-Encrypt-AES-128-Key,
PCKMO-Encrypt-AES-192-Key and PCKMO-Encrypt-AES-256-Key which deal
with protected keys. These pckmo subfunctions derive a protected key
from an AES clear key by encrypting it with an internal AES wrapping
key. More details about protected keys can be found in the
"z/Architecture Prinziples of Operation" document.
The qemu version provided here is only a fake intended to make
protected key available for developing and testing purpose:
* The protected key is 'derived' from the clear key by xoring
the fixed pattern 0xAAAA... onto the key value.
* The AES Wrapping Key Verification Pattern is a fixed
value of 32 bytes 0x0F0A0C0E0F0A0C0E...
Add preprocessor defines for the xor pattern and wkvp used to
construct ('encrypt') a protected key from a clear key value with
this implementation. Also add some static functions to 'encrypt'
from clear key to protected key and 'decrypt' back to cpacf_aes.c.
The preprocessor defines shall be used later in testcases to
construct and decode protected keys.

Support CPACF pcc subfunctions PCC-Compute-XTS-Parameter-Encrypted-AES-128
and PCC-Compute-XTS-Parameter-Encrypted-AES-128 but only for the special
case block sequential number is 0. However, this covers the s390 PAES XTS
implementation in the Linux kernel.

+CPACF Support
+=============
+
+CPACF
+-----
+
+CP Assist for Cryptographic Function (CPACF) is a hardware-integrated
+coprocessor feature built into every processor core of IBM Z and
+LinuxONE mainframes (s390x architecture). It provides high-speed,
+hardware-accelerated encryption and hashing directly on the CPU.
+
+CPACF provides a set of z/Architecture instructions (known as Message
+Security Assist or MSA) that execute cryptographic operations
+synchronously with the main processor.
+
+- Symmetric Encryption: Support for AES (128, 192, 256-bit), DES, and
+ Triple-DES (TDES).
+- Hashing: Acceleration for SHA-1, SHA-2 (up to SHA-512), SHA-3 and
+ SHAKE.
+- Random Number Generation: Pseudo Random Number Generator (PRNG) and
+ a hardware-based True Random Number Generator (TRNG).
+- Asymmetric Support: Elliptic Curve Cryptography (ECC) primitives
+ P-256, P-384, P-521, Montgomery/Edwards curves (e.g., Ed25519).
+
+Documentation about CPACF instructions is publicly available and
+can be found in the "z/Architecture Principles of Operation"
+accessible at the IBM documentation hub https://www.ibm.com/docs/en.
+For example the latest version as a pdf is available here:
+https://www.ibm.com/support/pages/zvm/library/other/22783214.pdf
+
+
+CPACF instructions
+------------------
+
+Here is a list of implemented CPACF instructions and the supported
+functions for each instruction:
+
+KDSA (COMPUTE DIGITAL SIGNATURE AUTHENTICATION)
+- Function code 0x00 - Function Query
+
+KIMD (COMPUTE INTERMEDIATE MESSAGE DIGEST)
+- Function code 0x00 - Function Query
+- Function code 0x02 - CPACF_KIMD_SHA_256
+- Function code 0x03 - CPACF_KIMD_SHA_512
+
+KLMD (COMPUTE LAST MESSAGE DIGEST)
+- Function code 0x00 - Function Query
+- Function code 0x02 - CPACF_KLMD_SHA_256
+- Function code 0x03 - CPACF_KLMD_SHA_512
+
+KM (CIPHER MESSAGE)
+- Function code 0x00 - Function Query
+- Function code 0x12 - CPACF_KM_AES_128
+- Function code 0x13 - CPACF_KM_AES_192
+- Function code 0x14 - CPACF_KM_AES_256
+- Function code 0x1a - CPACF_KM_PAES_128
+- Function code 0x1b - CPACF_KM_PAES_192
+- Function code 0x1c - CPACF_KM_PAES_256
+- Function code 0x32 - CPACF_KM_XTS_128
+- Function code 0x34 - CPACF_KM_XTS_256
+- Function code 0x3a - CPACF_KM_PXTS_128
+- Function code 0x3c - CPACF_KM_PXTS_256
+
+KMAC (COMPUTE MESSAGE AUTHENTICATION CODE)
+- Function code 0x00 - Function Query
+
+KMC (CIPHER MESSAGE WITH CHAINING)
+- Function code 0x00 - Function Query
+- Function code 0x12 - CPACF_KMC_AES_128
+- Function code 0x13 - CPACF_KMC_AES_192
+- Function code 0x14 - CPACF_KMC_AES_256
+- Function code 0x1a - CPACF_KMC_PAES_128
+- Function code 0x1b - CPACF_KMC_PAES_192
+- Function code 0x1c - CPACF_KMC_PAES_256
+
+KMCTR (CIPHER MESSAGE WITH COUNTER)
+- Function code 0x00 - Function Query
+- Function code 0x12 - CPACF_KMCTR_AES_128
+- Function code 0x13 - CPACF_KMCTR_AES_192
+- Function code 0x14 - CPACF_KMCTR_AES_256
+- Function code 0x1a - CPACF_KMCTR_PAES_128
+- Function code 0x1b - CPACF_KMCTR_PAES_192
+- Function code 0x1c - CPACF_KMCTR_PAES_256
+
+KMF (CIPHER MESSAGE WITH CIPHER FEEDBACK)
+- not supported
+
+KMO (CIPHER MESSAGE WITH OUTPUT FEEDBACK)
+- not supported
+
+PCC (PERFORM CRYPTOGRAPHIC COMPUTATION)
+- Function code 0x00 - Function Query
+- Function code 0x32 - compute XTS param AES-128
+- Function code 0x34 - compute XTS param AES-256
+- Function code 0x3a - compute XTS param Encrypted AES-128
+- Function code 0x3c - compute XTS param Encrypted AES-256
+
+PCKMO (PERFORM CRYPTOGRAPHIC KEY MANAGEMENT OPERATION)
+- Function code 0x00 - Function Query
+- Function code 0x12 - CPACF_PCKMO_ENC_AES_128_KEY
+- Function code 0x13 - CPACF_PCKMO_ENC_AES_192_KEY
+- Function code 0x14 - CPACF_PCKMO_ENC_AES_256_KEY
+
+PRNO (PERFORM RANDOM NUMBER OPERATION)
+- Function code 0x00 - Function Query
+- Function code 0x72 - CPACF_PRNO_TRNG
+
+Note that the use of a not supported CPACF instruction (KMF and KMO)
+or invocation of a not listed function will result in a Specification
+Exception.
+
+Not listed CPACF instructions (KMA, KMF, KMO) cause an Operation
+Exception when used. Not listed functions cause a Specification
+Exception when called. If only the query function is listed (KDSA),
+then the query function will return a function status word with all
+but the query function bit set to 0.
+
+
+Protected key support
+---------------------
+
+The qemu version for protected key support is only a fake provided
+here for developing and testing purpose:
+
+- The protected key is _derived_ from the clear key by xoring the
+ fixed pattern 0xAAAA... onto the key value.
+- The AES Wrapping Key Verification Pattern is a fixed value of 32
+ bytes 0x0F0A0C0E0F0A0C0E...
+
+The PCKMO instruction implementation does exactly this - _derive_ a
+_protected_ key from the clear key given by xor 0xAAAA... and writing
+the fixed value for the WKVP of 0x0F0A0C0E0F0A0C0E... into the blob.
+The other subfunctions of the CPACF instructions dealing with
+protected key treat the protected key blob by first checking for the
+WKVP (against the fixed value of 0x0F0A0C0E0F0A0C0E...) and second
+_decrypting_ the key value by xoring 0xAAAA... and then execute the
+clear key operation with the decrypted key value.
+This is suitable for testing purpose but such keys are not for real
+production load and would open up a huge security breach!
+
+For more details about protected keys see the "z/Architecture
+Principles of Operation" document chapter "General Instructions"
+sub-chapter "Protection of Cryptographic Keys" and again the
+implementation here does NOT implement what is explained there.

Add simple tests for the CPACF instructions implemented:
- kdsa - minimal as only query is implemented
- kimd - query, sha256, sha512
- klmd - query, sha256, sha512
- km - query, aes 128, 192, 256 with clear and prot key
- kmac - minimal as only query is implemented
- kmc - query, aes 128, 192, 256 with clear and prot key
- kmctr - query, aes 128, 192, 256 with clear and prot key
- pcc - query, xts aes 128, 256 and prot key xts aes 128, 256
- pckmo - run query and check for SIGILL
- prno - query, trng
No test for kma, kmf, kmo as these instructions are currently
not implemented at all.
