Hello crypto maintainers! We've found and example of the ipsec algorithm combination, which doesn't fit into CRYPTO_MAX_ALG_NAME long buffers: ip x s add src 1.1.1.1 dst 1.1.1.2 proto esp spi 0 mode tunnel enc des3_ede 0x0 auth sha256 0x0 flag esn replay-window 256 produces "echainiv(authencesn(hmac(sha256-generic),cbc(des3_ede-generic)))" on the machines without optimized crypto drivers, which doesn't fit into current 64-bytes buffers. I see two possible options: a) split CRYPTO_MAX_ALG_NAME into CRYPTO_MAX_ALG_NAME + CRYPTO_MAX_DRV_NAME pair and make later, say, 96, because the former probably cannot be changed because of numerous user-space exports. And change half of the code to use new define. b) rename *-generic algorithms to *-gen, so that cra_driver_name will be shortened, while MODULE_ALIAS_CRYPTO() could still be maintained in old and new form. What are your thoughts? -- Best regards, Alexander Sverdlin.
