ssh: add server side multi-step authentication

2024-04-03T07:40:24Z

Add support for sending back partial success to the client while handling authentication in the server. This is implemented by a special error that can be returned by any of the authentication methods, which contains the authentication methods to offer next. This patch is based on CL 399075 with some minor changes and the addition of test cases.

x/crypto/chacha20: cleanup chacha_ppc64le.s

2024-03-26T21:57:38Z

- Adding PCALIGN before the loops - Changing WORD directive with corresponding Vector Merge EVEN/ODD word instructions - Replacing Branch Conditional (BC) with its extended mnemonic form BDNZ - VPERMXOR instruction usage in place of VXOR instructions followed by VRLW (rotate left) for cases of rotating in multiples of 8. This replacements give performace improvement both in time and space of around 7%-8% as listed below using benchstat tool. goos: linux goarch: ppc64le pkg: golang.org/x/crypto/chacha20 cpu: POWER10 | chacha20.prev.out | chacha20.new.out | | sec/op | sec/op vs base | ChaCha20/64 171.9n ± 0% 156.6n ± 1% -8.90% (p=0.002 n=6) ChaCha20/256 165.5n ± 0% 152.4n ± 0% -7.92% (p=0.002 n=6) ChaCha20/10x25 505.8n ± 0% 504.3n ± 2% -0.32% (p=0.589 n=6) ChaCha20/4096 2.265µ ± 0% 2.052µ ± 0% -9.40% (p=0.002 n=6) ChaCha20/100x40 5.359µ ± 3% 5.018µ ± 2% -6.37% (p=0.002 n=6) ChaCha20/65536 35.71µ ± 0% 32.29µ ± 0% -9.57% (p=0.002 n=6) ChaCha20/1000x65 44.63µ ± 0% 41.05µ ± 0% -8.02% (p=0.002 n=6) geomean 2.235µ 2.073µ -7.26% | chacha20.prev.out | chacha20.new.out | | B/s | B/s vs base | ChaCha20/64 355.1Mi ± 0% 389.8Mi ± 1% +9.78% (p=0.002 n=6) ChaCha20/256 1.440Gi ± 0% 1.565Gi ± 0% +8.62% (p=0.002 n=6) ChaCha20/10x25 471.3Mi ± 0% 472.8Mi ± 2% +0.31% (p=0.589 n=6) ChaCha20/4096 1.684Gi ± 0% 1.859Gi ± 0% +10.38% (p=0.002 n=6) ChaCha20/100x40 711.8Mi ± 3% 760.3Mi ± 2% +6.80% (p=0.002 n=6) ChaCha20/65536 1.709Gi ± 0% 1.890Gi ± 0% +10.59% (p=0.002 n=6) ChaCha20/1000x65 1.356Gi ± 0% 1.475Gi ± 0% +8.72% (p=0.002 n=6) geomean 957.3Mi 1.008Gi +7.83% Change-Id: Ib31cb10a2a11eacdacf0272fbfd887eb5ccd8bcb Reviewed-on: https://go-review.googlesource.com/c/crypto/+/564797 Reviewed-by: Lynn Boger Run-TryBot: Paul Murphy TryBot-Result: Gopher Robot Reviewed-by: David Chase LUCI-TryBot-Result: Go LUCI Run-TryBot: Lynn Boger Reviewed-by: Cherry Mui
