sha3: fix cSHAKE initialization for extremely large N and or S

2024-09-30T15:41:13Z

While both impractical and unlikely, the multiplication could overflow on 32-bit architectures. The 64-bit architecture case is unaffected by both the maximum length of Go slices being too small to trigger the overflow (everything except s390), and it being safe to assume no machine has more than 2 EiB of memory.

ssh: return ServerAuthError after too many auth failures

2024-09-16T20:42:53Z

if a client is disconnected due to too many authentication attempts we should return a ServerAuthError instead of a generic error. Some users check the error returned by NewServerConn to determine whether or not a client attempted to authenticate.

These were problematic but previously easy to miss. They're now easy to spot thanks to build failures at Go tip as of CL 610736. For golang/go#68796.

internal/poly1305: Port sum_amd64.s to Avo

chacha20poly1305: Avo port of chacha20poly1305_amd64.s

This implementation utilizes the same registers found in the reference implementation, aiming to produce a minimal semantic diff between the Avo-generated output and the original hand-written assembly. To verify the Avo implementation, the reference and Avo-generated assembly files are fed to `go tool asm`, capturing the debug output into corresponding temp files. The debug output contains supplementary metadata (line numbers, instruction offsets, and source file references) that must be removed in order to obtain a semantic diff of the two files. This is accomplished via a small utility script written in awk. Parameter metadata not found in the reference assembly file has been added, leading to a diff on the lines where those symbols are referenced. Commands used to verify Avo output: GOROOT=$(go env GOROOT) ASM_PATH="chacha20poly1305/chacha20poly1305_amd64.s" REFERENCE="b2d3a6a4b4d36521cd7f653879cf6981e7c5c340" go tool asm -o /dev/null -I "$GOROOT"/src/runtime -debug \ <(git cat-file -p "$REFERENCE:$ASM_PATH") \ > /tmp/reference.s go tool asm -o /dev/null -I "$GOROOT"/src/runtime -debug \ "$ASM_PATH" \ > /tmp/avo.s normalize(){ awk '{ $1=$2=$3=""; print substr($0,4) }' } diff <(normalize < /tmp/reference.s) <(normalize < /tmp/avo.s) 155,157c155,157 < MOVQ dst(FP), DI < MOVQ key+24(FP), R8 < MOVQ src+48(FP), SI --- > MOVQ dst_base(FP), DI > MOVQ key_base+24(FP), R8 > MOVQ src_base+48(FP), SI 159c159 < MOVQ ad+72(FP), CX --- > MOVQ ad_base+72(FP), CX 4684,4686c4684,4686 < MOVQ dst(FP), DI < MOVQ key+24(FP), R8 < MOVQ src+48(FP), SI --- > MOVQ dst_base(FP), DI > MOVQ key_base+24(FP), R8 > MOVQ src_base+48(FP), SI 4688c4688 < MOVQ ad+72(FP), CX --- > MOVQ ad_base+72(FP), CX Change-Id: Ia3a8e70b7440944ee739499c41ddceb70e054ef9 Reviewed-on: https://go-review.googlesource.com/c/crypto/+/601442 Reviewed-by: Filippo Valsorda LUCI-TryBot-Result: Go LUCI Reviewed-by: Roland Shoemaker Reviewed-by: Dmitri Shuralyov
