Author: jhb Date: Mon Jun 10 19:26:57 2019 New Revision: 348876 URL: https://svnweb.freebsd.org/changeset/base/348876 Log: Add warnings to /dev/crypto for deprecated algorithms. These algorithms are deprecated algorithms that will have no in-kernel consumers in FreeBSD 13. Specifically, deprecate the following algorithms: - ARC4 - Blowfish - CAST128 - DES - 3DES - MD5-HMAC - Skipjack MFC after: 1 month Relnotes: yes Sponsored by: Chelsio Communications Differential Revision: https://reviews.freebsd.org/D20554 Modified: head/sys/opencrypto/cryptodev.c Modified: head/sys/opencrypto/cryptodev.c ============================================================================== --- head/sys/opencrypto/cryptodev.c Mon Jun 10 19:22:36 2019 (r348875) +++ head/sys/opencrypto/cryptodev.c Mon Jun 10 19:26:57 2019 (r348876) @@ -386,6 +386,9 @@ cryptof_ioctl( struct crypt_op copc; struct crypt_kop kopc; #endif + static struct timeval arc4warn, blfwarn, castwarn, deswarn, md5warn; + static struct timeval skipwarn, tdeswarn; + static struct timeval warninterval = { .tv_sec = 60, .tv_usec = 0 }; switch (cmd) { case CIOCGSESSION: @@ -406,18 +409,28 @@ cryptof_ioctl( case 0: break; case CRYPTO_DES_CBC: + if (ratecheck(&deswarn, &warninterval)) + gone_in(13, "DES cipher via /dev/crypto"); txform = &enc_xform_des; break; case CRYPTO_3DES_CBC: + if (ratecheck(&tdeswarn, &warninterval)) + gone_in(13, "3DES cipher via /dev/crypto"); txform = &enc_xform_3des; break; case CRYPTO_BLF_CBC: + if (ratecheck(&blfwarn, &warninterval)) + gone_in(13, "Blowfish cipher via /dev/crypto"); txform = &enc_xform_blf; break; case CRYPTO_CAST_CBC: + if (ratecheck(&castwarn, &warninterval)) + gone_in(13, "CAST128 cipher via /dev/crypto"); txform = &enc_xform_cast5; break; case CRYPTO_SKIPJACK_CBC: + if (ratecheck(&skipwarn, &warninterval)) + gone_in(13, "Skipjack cipher via /dev/crypto"); txform = &enc_xform_skipjack; break; case CRYPTO_AES_CBC: @@ -430,6 +443,8 @@ cryptof_ioctl( txform = &enc_xform_null; break; case CRYPTO_ARC4: + if (ratecheck(&arc4warn, &warninterval)) + gone_in(13, "ARC4 cipher via /dev/crypto"); txform = &enc_xform_arc4; break; case CRYPTO_CAMELLIA_CBC: @@ -458,6 +473,9 @@ cryptof_ioctl( case 0: break; case CRYPTO_MD5_HMAC: + if (ratecheck(&md5warn, &warninterval)) + gone_in(13, + "MD5-HMAC authenticator via /dev/crypto"); thash = &auth_hash_hmac_md5; break; case CRYPTO_POLY1305:
