The list_empty case in crypto_alg_match() will return without calling up_read() on crypto_alg_sem. We could do the "goto out" routine, but the function will clearly do the right thing with that test simply removed. Signed-off-by:

The CDPR (Current Descriptor Pointer Register) can be unreliable when trying to locate an offending descriptor. Handle that case by (a) not OOPSing, and (b) reverting to the machine internal copy of the descriptor header in order to report the correct execution unit error. Note: printing all execution units' ISRs is not effective because it results in an internal time out (ITO) error and the EU resetting its ISR value (at least when specifying an invalid key length on an SEC 2.2/MPC8313E).

Patch adds 3-way parallel x86_64 assembly implementation of twofish as new module. New assembler functions crypt data in three blocks chunks, improving cipher performance on out-of-order CPUs. Patch has been tested with tcrypt and automated filesystem tests. Summary of the tcrypt benchmarks: Twofish 3-way-asm vs twofish asm (128bit 8kb block ECB) encrypt: 1.3x speed decrypt: 1.3x speed Twofish 3-way-asm vs twofish asm (128bit 8kb block CBC) encrypt: 1.07x speed decrypt: 1.4x speed Twofish 3-way-asm vs twofish asm (128bit 8kb block CTR) encrypt: 1.4x speed Twofish 3-way-asm vs AES asm (128bit 8kb block ECB) encrypt: 1.0x speed decrypt: 1.0x speed Twofish 3-way-asm vs AES asm (128bit 8kb block CBC) encrypt: 0.84x speed decrypt: 1.09x speed Twofish 3-way-asm vs AES asm (128bit 8kb block CTR) encrypt: 1.15x speed Full output: http://koti.mbnet.fi/axh/kernel/crypto/tcrypt-speed-twofish-3way-asm-x86_64.txt http://koti.mbnet.fi/axh/kernel/crypto/tcrypt-speed-twofish-asm-x86_64.txt http://koti.mbnet.fi/axh/kernel/crypto/tcrypt-speed-aes-asm-x86_64.txt Tests were run on: vendor_id : AuthenticAMD cpu family : 16 model : 10 model name : AMD Phenom(tm) II X6 1055T Processor Also userspace test were run on: vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Xeon(R) CPU E7330 @ 2.40GHz stepping : 11 Userspace test results: Encryption/decryption of twofish 3-way vs x86_64-asm on AMD Phenom II: encrypt: 1.27x decrypt: 1.25x Encryption/decryption of twofish 3-way vs x86_64-asm on Intel Xeon E7330: encrypt: 1.36x decrypt: 1.36x Signed-off-by:

This patch adds improved F-macro for 4-way parallel functions. With new F-macro for 4-way parallel functions, blowfish sees ~15% improvement in speed tests on AMD Phenom II (~5% on Intel Xeon E7330). However when used in 1-way blowfish function new macro would be ~10% slower than original, so old F-macro is kept for 1-way functions. Patch cleans up old F-macro as it is no longer needed in 4-way part. Patch also does register macro renaming to reduce stack usage. Signed-off-by:

Patch adds x86_64 assembly implementation of blowfish. Two set of assembler functions are provided. First set is regular 'one-block at time' encrypt/decrypt functions. Second is 'four-block at time' functions that gain performance increase on out-of-order CPUs. Performance of 4-way functions should be equal to 1-way functions with in-order CPUs. Summary of the tcrypt benchmarks: Blowfish assembler vs blowfish C (256bit 8kb block ECB) encrypt: 2.2x speed decrypt: 2.3x speed Blowfish assembler vs blowfish C (256bit 8kb block CBC) encrypt: 1.12x speed decrypt: 2.5x speed Blowfish assembler vs blowfish C (256bit 8kb block CTR) encrypt: 2.5x speed Full output: http://koti.mbnet.fi/axh/kernel/crypto/tcrypt-speed-blowfish-asm-x86_64.txt http://koti.mbnet.fi/axh/kernel/crypto/tcrypt-speed-blowfish-c-x86_64.txt Tests were run on: vendor_id : AuthenticAMD cpu family : 16 model : 10 model name : AMD Phenom(tm) II X6 1055T Processor stepping : 0 Signed-off-by:

As cryptd is depeneded on by other algorithms such as aesni-intel, it needs to be registered before them. When everything is built as modules, this occurs naturally. However, for this to work when they are built-in, we need to use subsys_initcall in cryptd. Tested-by:
