Pull security subsystem updates from James Morris: "Highlights: - PKCS#7 support added to support signed kexec, also utilized for module signing. See comments in 3f1e1bea. ** NOTE: this requires linking against the OpenSSL library, which must be installed, e.g. the openssl-devel on Fedora ** - Smack - add IPv6 host labeling; ignore labels on kernel threads - support smack labeling mounts which use binary mount data - SELinux: - add ioctl whitelisting (see http://kernsec.org/files/lss2015/vanderstoep.pdf) - fix mprotect PROT_EXEC regression caused by mm change - Seccomp: - add ptrace options for suspend/resume" * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (57 commits) PKCS#7: Add OIDs for sha224, sha284 and sha512 hash algos and use them Documentation/Changes: Now need OpenSSL devel packages for module signing scripts: add extract-cert and sign-file to .gitignore modsign: Handle signing key in source tree modsign: Use if_changed rule for extracting cert from module signing key Move certificate handling to its own directory sign-file: Fix warning about BIO_reset() return value PKCS#7: Add MODULE_LICENSE() to test module Smack - Fix build error with bringup unconfigured sign-file: Document dependency on OpenSSL devel libraries PKCS#7: Appropriately restrict authenticated attributes and content type KEYS: Add a name for PKEY_ID_PKCS7 PKCS#7: Improve and export the X.509 ASN.1 time object decoder modsign: Use extract-cert to process CONFIG_SYSTEM_TRUSTED_KEYS extract-cert: Cope with multiple X.509 certificates in a single file sign-file: Generate CMS message as signature instead of PKCS#7 PKCS#7: Support CMS messages also [RFC5652] X.509: Change recorded SKID & AKID to not include Subject or Issuer PKCS#7: Check content type and versions MAINTAINERS: The keyrings mailing list has moved ...

crypto: poly1305 - Add a SSE2 SIMD variant for x86_64

2015-07-17T13:20:27Z

Implements an x86_64 assembler driver for the Poly1305 authenticator. This single block variant holds the 130-bit integer in 5 32-bit words, but uses SSE to do two multiplications/additions in parallel. When calling updates with small blocks, the overhead for kernel_fpu_begin/ kernel_fpu_end() negates the perfmance gain. We therefore use the poly1305-generic fallback for small updates. For large messages, throughput increases by ~5-10% compared to poly1305-generic: testing speed of poly1305 (poly1305-generic) test 0 ( 96 byte blocks, 16 bytes per update, 6 updates): 4080026 opers/sec, 391682496 bytes/sec test 1 ( 96 byte blocks, 32 bytes per update, 3 updates): 6221094 opers/sec, 597225024 bytes/sec test 2 ( 96 byte blocks, 96 bytes per update, 1 updates): 9609750 opers/sec, 922536057 bytes/sec test 3 ( 288 byte blocks, 16 bytes per update, 18 updates): 1459379 opers/sec, 420301267 bytes/sec test 4 ( 288 byte blocks, 32 bytes per update, 9 updates): 2115179 opers/sec, 609171609 bytes/sec test 5 ( 288 byte blocks, 288 bytes per update, 1 updates): 3729874 opers/sec, 1074203856 bytes/sec test 6 ( 1056 byte blocks, 32 bytes per update, 33 updates): 593000 opers/sec, 626208000 bytes/sec test 7 ( 1056 byte blocks, 1056 bytes per update, 1 updates): 1081536 opers/sec, 1142102332 bytes/sec test 8 ( 2080 byte blocks, 32 bytes per update, 65 updates): 302077 opers/sec, 628320576 bytes/sec test 9 ( 2080 byte blocks, 2080 bytes per update, 1 updates): 554384 opers/sec, 1153120176 bytes/sec test 10 ( 4128 byte blocks, 4128 bytes per update, 1 updates): 278715 opers/sec, 1150536345 bytes/sec test 11 ( 8224 byte blocks, 8224 bytes per update, 1 updates): 140202 opers/sec, 1153022070 bytes/sec testing speed of poly1305 (poly1305-simd) test 0 ( 96 byte blocks, 16 bytes per update, 6 updates): 3790063 opers/sec, 363846076 bytes/sec test 1 ( 96 byte blocks, 32 bytes per update, 3 updates): 5913378 opers/sec, 567684355 bytes/sec test 2 ( 96 byte blocks, 96 bytes per update, 1 updates): 9352574 opers/sec, 897847104 bytes/sec test 3 ( 288 byte blocks, 16 bytes per update, 18 updates): 1362145 opers/sec, 392297990 bytes/sec test 4 ( 288 byte blocks, 32 bytes per update, 9 updates): 2007075 opers/sec, 578037628 bytes/sec test 5 ( 288 byte blocks, 288 bytes per update, 1 updates): 3709811 opers/sec, 1068425798 bytes/sec test 6 ( 1056 byte blocks, 32 bytes per update, 33 updates): 566272 opers/sec, 597984182 bytes/sec test 7 ( 1056 byte blocks, 1056 bytes per update, 1 updates): 1111657 opers/sec, 1173910108 bytes/sec test 8 ( 2080 byte blocks, 32 bytes per update, 65 updates): 288857 opers/sec, 600823808 bytes/sec test 9 ( 2080 byte blocks, 2080 bytes per update, 1 updates): 590746 opers/sec, 1228751888 bytes/sec test 10 ( 4128 byte blocks, 4128 bytes per update, 1 updates): 301825 opers/sec, 1245936902 bytes/sec test 11 ( 8224 byte blocks, 8224 bytes per update, 1 updates): 153075 opers/sec, 1258896201 bytes/sec Benchmark results from a Core i5-4670T.
