use errorf() while nameref states were being changed (by almost completely
eliminating the global variable) and the readonly first array variable
bypass (typo/refactoro); also, whitespace, one int → bool, and add a
comment wrt. the parser rewrite talked about with igli during a fever ;)
• keep the Kochan book at 3rd edition because 4th is not a paper book
• keep POSIX at 1993 because I’m actually unable to find an ISBN or
other bib ref for the 2013 version…
This uses NZAAT Init and Update, and AES MixColumns for Finish.
For hashtables this will need XOR with uint32_t then rotation
with uint5_t (so a total of 37 bit of entropy) for mitigation.
For entropy avalanche this needs mixing, and better handling
of the IV and/or the first four bytes, see BAFHHost* macros.
Thanks to Bob Jenkins for the one-at-a-time hash, Bret Mulvey for
the Hash.cs AvalancheTest, Jonathan “ciruZ” Schleifer and Dominik
“Natureshadow” George for discussion, Theodore “Ted” Ts'o for valuable
input on arc4random_roundhash, “poncho” for suggesting and Orson
“nightcracker” Peters for implementing MixColumns, tarent GmbH for
letting me test this empirically on a 64 GiB RAM machine.
‣ not like oksh did, but using mksh’s built-in features
• handle suggested __pure additions
• revert cid 1004F7F096867C83CF0
‣ always use our wcwidth code
‣ only use our strlcpy code if none found
• fix a couple of gcc-snapshot and clang/scan-build warnings
• mksh R49~rc1
suggested in http://crypto.stackexchange.com/questions/12145
• add pure mksh™ implementation, too, while here (since it can
replace NZAATFinish even though NZATMix is slower, both are
bijective)
one set of CTRL, UNCTRL, and new ISCTRL macros) C0 and DEL handling; the
optimisation only works for 7-bit ASCII, so those places 8-bit must pass
intact have an added check
also, while here, remove an editor oops (‘;’), oksh rcsid sync (they did
accept I was right wrt. set -e), int → bool, and code merge/cleanup
Add a proper suspend builtin that saves/restores the tty and pgrp
as needed instead of an alias that just sends SIGSTOP. Login shells
may be suspended if they are not running in an orphan process group.
