s390/zcrypt: remove CEX2 and CEX3 device drivers

2023-07-24T10:12:22+00:00

Remove the legacy device driver code for CEX2 and CEX3 cards. The last machines which are able to handle CEX2 crypto cards are z10 EC first available 2008 and z10 BC first available 2009. The last machines able to handle a CEX3 crypto card are z196 first available 2010 and z114 first available 2011. Please note that this does not imply to drop CEX2 and CEX3 support in general. With older kernels on hardware up to the aforementioned machine models these crypto cards will get support by IBM. The removal of the CEX2 and CEX3 device drivers code opens up some simplifications, for example support for crypto cards without rng support can be removed also.

Pull more s390 updates from Alexander Gordeev: - Fix virtual vs physical address confusion in vmem_add_range() and vmem_remove_range() functions - Include instead of and throughout s390 code - Make all PSW related defines also available for assembler files. Remove PSW_DEFAULT_KEY define from uapi for that - When adding an undefined symbol the build still succeeds, but userspace crashes trying to execute VDSO, because the symbol is not resolved. Add undefined symbols check to prevent that - Use kvmalloc_array() instead of kzalloc() for allocaton of 256k memory when executing s390 crypto adapter IOCTL - Add -fPIE flag to prevent decompressor misaligned symbol build error with clang - Use .balign instead of .align everywhere. This is a no-op for s390, but with this there no mix in using .align and .balign anymore - Filter out -mno-pic-data-is-text-relative flag when compiling kernel to prevent VDSO build error - Rework entering of DAT-on mode on CPU restart to use PSW_KERNEL_BITS mask directly - Do not retry administrative requests to some s390 crypto cards, since the firmware assumes replay attacks - Remove most of the debug code, which is build in when kernel config option CONFIG_ZCRYPT_DEBUG is enabled - Remove CONFIG_ZCRYPT_MULTIDEVNODES kernel config option and switch off the multiple devices support for the s390 zcrypt device driver - With the conversion to generic entry machine checks are accounted to the current context instead of irq time. As result, the STCKF instruction at the beginning of the machine check handler and the lowcore member are no longer required, therefore remove it - Fix various typos found with codespell - Minor cleanups to CPU-measurement Counter and Sampling Facilities code - Revert patch that removes VMEM_MAX_PHYS macro, since it causes a regression * tag 's390-6.5-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (25 commits) Revert "s390/mm: get rid of VMEM_MAX_PHYS macro" s390/cpum_sf: remove check on CPU being online s390/cpum_sf: handle casts consistently s390/cpum_sf: remove unnecessary debug statement s390/cpum_sf: remove parameter in call to pr_err s390/cpum_sf: simplify function setup_pmu_cpu s390/cpum_cf: remove unneeded debug statements s390/entry: remove mcck clock s390: fix various typos s390/zcrypt: remove ZCRYPT_MULTIDEVNODES kernel config option s390/zcrypt: do not retry administrative requests s390/zcrypt: cleanup some debug code s390/entry: rework entering DAT-on mode on CPU restart s390/mm: fence off VM macros from asm and linker s390: include linux/io.h instead of asm/io.h s390/ptrace: make all psw related defines also available for asm s390/ptrace: remove PSW_DEFAULT_KEY from uapi s390/vdso: filter out mno-pic-data-is-text-relative cflag s390: consistently use .balign instead of .align s390/decompressor: fix misaligned symbol build error ...

s390/zcrypt: remove ZCRYPT_MULTIDEVNODES kernel config option

2023-07-03T09:19:41+00:00

Remove ZCRYPT_MULTIDEVNODES kernel config option and make the dependent code always build. The last years showed, that this option is enabled on all distros and exploited by some features (for example CEX plugin for kubernetes). So remove this choice as it was never used to switch off the multiple devices support for the zcrypt device driver.

With the growing number of Intel crypto drivers, it makes sense to group them all into a single drivers/crypto/intel/ directory. Create a separate drivers/crypto/intel/ixp4xx directory and move drivers/crypto/ixp4xx_crypto.c to it, along with a new Kconfig and Makefile to contain the config and make bits. Also add a COMPILE_TEST dependency to CRYPTO_DEV_IXP4XX so it can be more easily compile-tested. Signed-off-by: Tom Zanussi Acked-by: Corentin LABBE Signed-off-by: Herbert Xu

2023-03-31T09:50:09+00:00

The SA2UL Crypto driver provides support for couple of DES3 algos "cbc(des3_ede)" and "ecb(des3_ede)", and enabling the crypto selftest throws the following errors (as seen on K3 J721E SoCs): saul-crypto 4e00000.crypto: Error allocating fallback algo cbc(des3_ede) alg: skcipher: failed to allocate transform for cbc-des3-sa2ul: -2 saul-crypto 4e00000.crypto: Error allocating fallback algo ecb(des3_ede) alg: skcipher: failed to allocate transform for ecb-des3-sa2ul: -2 Fix this by selecting CRYPTO_DES which was missed while adding base driver support.
