This series introduces a flag that algorithms can set to indicate that they allocate memory during processing of typical inputs, and thus shouldn't be used in cases like dm-crypt where memory allocation failures aren't acceptable. Compared to Mikulas's patches, I've made the following improvements: - Tried to clearly document the semantics of CRYPTO_ALG_ALLOCATES_MEMORY. This includes documenting the usage constraints, since there are actually lots of cases that were overlooked where algorithms can still allocate memory in some edge cases where inputs are misaligned, fragemented, etc. E.g. see crypto/skcipher.c and crypto/ahash.c. Mikulas, please let me know if there are any concerns for dm-crypt. - Moved the common mechanism for inheriting flags to its own patch. - crypto_grab_spawn() now handles propagating CRYPTO_ALG_INHERITED_FLAGS to the new template instance. - Inherit the flags in various places that were missed. - Other cleanups. Note: Mikulas's patch "crypto: set the flag CRYPTO_ALG_ALLOCATES_MEMORY" still needs to be checked for cases where the flag no longer needs to be set due to the usage constraints I documented. Eric Biggers (4): crypto: geniv - remove unneeded arguments from aead_geniv_alloc() crypto: algapi - use common mechanism for inheriting flags crypto: algapi - introduce the flag CRYPTO_ALG_ALLOCATES_MEMORY crypto: algapi - remove crypto_check_attr_type() Mikulas Patocka (2): crypto: set the flag CRYPTO_ALG_ALLOCATES_MEMORY dm-crypt: don't use drivers that have CRYPTO_ALG_ALLOCATES_MEMORY crypto/adiantum.c | 4 +- crypto/algapi.c | 17 +-- crypto/authenc.c | 4 +- crypto/authencesn.c | 4 +- crypto/ccm.c | 23 ++-- crypto/chacha20poly1305.c | 4 +- crypto/cmac.c | 15 ++- crypto/cryptd.c | 59 ++++----- crypto/ctr.c | 8 +- crypto/cts.c | 3 +- crypto/echainiv.c | 2 +- crypto/essiv.c | 11 +- crypto/gcm.c | 10 +- crypto/geniv.c | 9 +- crypto/hmac.c | 15 ++- crypto/lrw.c | 3 +- crypto/pcrypt.c | 14 +-- crypto/rsa-pkcs1pad.c | 3 +- crypto/seqiv.c | 2 +- crypto/simd.c | 6 +- crypto/skcipher.c | 3 +- crypto/vmac.c | 15 ++- crypto/xcbc.c | 15 ++- crypto/xts.c | 3 +- .../crypto/allwinner/sun8i-ce/sun8i-ce-core.c | 12 +- .../crypto/allwinner/sun8i-ss/sun8i-ss-core.c | 12 +- drivers/crypto/amlogic/amlogic-gxl-core.c | 6 +- drivers/crypto/axis/artpec6_crypto.c | 20 ++- drivers/crypto/bcm/cipher.c | 72 ++++++++--- drivers/crypto/caam/caamalg.c | 6 +- drivers/crypto/caam/caamalg_qi.c | 6 +- drivers/crypto/caam/caamalg_qi2.c | 8 +- drivers/crypto/caam/caamhash.c | 2 +- drivers/crypto/cavium/cpt/cptvf_algs.c | 18 ++- drivers/crypto/cavium/nitrox/nitrox_aead.c | 4 +- .../crypto/cavium/nitrox/nitrox_skcipher.c | 16 +-- drivers/crypto/ccp/ccp-crypto-aes-cmac.c | 1 + drivers/crypto/ccp/ccp-crypto-aes-galois.c | 1 + drivers/crypto/ccp/ccp-crypto-aes-xts.c | 1 + drivers/crypto/ccp/ccp-crypto-aes.c | 2 + drivers/crypto/ccp/ccp-crypto-des3.c | 1 + drivers/crypto/ccp/ccp-crypto-sha.c | 1 + drivers/crypto/chelsio/chcr_algo.c | 7 +- drivers/crypto/hisilicon/sec/sec_algs.c | 24 ++-- drivers/crypto/hisilicon/sec2/sec_crypto.c | 4 +- .../crypto/inside-secure/safexcel_cipher.c | 47 +++++++ drivers/crypto/inside-secure/safexcel_hash.c | 18 +++ drivers/crypto/ixp4xx_crypto.c | 6 +- drivers/crypto/marvell/cesa/cipher.c | 18 ++- drivers/crypto/marvell/cesa/hash.c | 6 + .../crypto/marvell/octeontx/otx_cptvf_algs.c | 30 ++--- drivers/crypto/n2_core.c | 3 +- drivers/crypto/picoxcell_crypto.c | 17 ++- drivers/crypto/qat/qat_common/qat_algs.c | 12 +- drivers/crypto/qce/skcipher.c | 1 + drivers/crypto/talitos.c | 117 ++++++++++++------ drivers/crypto/virtio/virtio_crypto_algs.c | 3 +- drivers/crypto/xilinx/zynqmp-aes-gcm.c | 1 + drivers/md/dm-crypt.c | 17 ++- include/crypto/algapi.h | 23 +++- include/crypto/internal/geniv.h | 2 +- include/linux/crypto.h | 32 +++++ 62 files changed, 550 insertions(+), 279 deletions(-) -- 2.27.0
