libkeccak's Introduction
NAME libkeccak - Keccak-family hashing library DESCRIPTION libkeccak is a bit-oriented lanewise implementation of the Keccak-family with support for extend output size, state marshalling, algorithm tuning with implicit parameters, secure erasure of sensitive data, and HMAC. RATIONALE Keccak won the SHA-3 competition. We need a library for it, and let it be bit-oriented. SEE ALSO sha3sum, libblake(7), libsha2(7), libsha1(7)

fail to keccak_bits(256, "\x00", 0)
i use this code
keccak_bits(256, "\x00", 0)
but the result is not correct.
Divergence between macOS and Debian from 4096 chars
Hi,
keccak-256sum -x return different results for mac and debian when hashed string is greater or equal to 4096 characters.
Examples :
For 4095 characters. both on debian and mac.

I would appreciate any clue.
Thank you
Where in the world?
Could you add a fancy option where one could trace the origins of all of the output bits? Like, where in the data source did the first bit originate from? Or, what happened to the first bit in the input? So, let's say it's a zero. Did it become a one or remain a zero and where in the world is it? You can assume that the input size is the same as the output size.

Stack-overrun segfault when operating on files with large st_blksize (e.g. in a modern tmpfs which may use hugepage backing)
Initial summary
I was attempting to use the sha3sum utilities (which use libkeccak) today, and every single time I tried to run any of them, I'd get a segfault in libkeccak_generalised_sum_fd.
I traced it back to the alloca call in that function. And the debugger showed blksize = 2097152 (2 MiB).
So clearly what's happening here, is that if the file being operated on reports a large st_blksize when fstat'd, libkeccak will blindly attempt to alloca a giant chunk of memory of that block size, regardless of whether it's super-giant and literally exceeds the stack size given to the thread that the function is executing inside (which is exactly what was happening in my particular case).
Thread stack size considerations
I believe the default thread stack size limits on Linux are 2 MiB for x86_32, and 8 MiB for x86_64. The machine I'm using is 64-bit; however in my /etc/security/limits.conf, I long ago intentionally reduced the soft RLIMIT_STACK value to 2 MiB, in an effort to curtail excess memory usage by highly-threaded programs.
* soft stack 2048
Also note that different distributions may well tweak the standard defaults to other values. And additionally that any program that happens to use libkeccak may quite plausibly explicitly call pthread_attr_setstacksize somewhere in its execution to change its own stack size limit for program-specific reasons.
So, to summarize, what I'm saying here is that you can't really assume a whole lot about the upper bound on stack size (other than that on sane systems it'll probably be at least 1 MiB).
File system block size circumstances
Now, as for situations in which st_blksize may plausibly be quite large (too large for it to be safe to simply alloca that amount of memory without worrying about potentially overrunning the stack), there are actually quite a few.
There are many file systems that allow configuring rather large block/cluster sizes for specific use cases. The case I'm most familiar with is ZFS; but I know that many other file systems have similar capabilities.
Additionally, a very common large-block-size situation, that you likely wouldn't immediately think of, is actually Linux tmpfs. Classically, as a RAM-backed filesystem, the block size reported by tmpfs has been equal to the page size (4096 bytes).
However, starting with kernel 4.7.0, tmpfs gained the ability to use THP (transparent hugepages) to facilitate the use of 2 MiB pages on x86-architecture systems, in certain circumstances, for backing larger files. (See the description of mount option huge= in man page tmpfs(5).) One important consequence of this feature is that stat syscalls on tmpfs may very well return st_blksize = 2097152 (2 MiB, the size of a standard x86 hugepage). And that's pretty damn large.
The problematic combination
In my particular use case, I had the following combination:
- The file I was hashing was situated on a THP-enabled tmpfs filesystem, and therefore reported
st_blksize = 2097152. - The thread stack size limit was 2 MiB, i.e. 2097152 bytes.
Given that some small amount of stack was inevitably going to have already been used by caller stack frames, it was inevitable that libkeccak_generalised_sum_fd would segfault when it hit the alloca call.
Potential solutions
- Continue using
alloca, but cap the allowable value of theblksizevariable after assignment fromst_blksizeto a "reasonable maximum", like 64 KiB (something in that ballpark) - Get rid of
allocaand usemallocfor the buffer instead- Will need a check-for-
NULL-and-return--1path obviously - Requires giving
chunkan initial value ofNULLat declaration, and then ensuring that all function return paths callfree(chunk)- Could be made a bit tidier with the
goto-label-at-end-of-function-upon-failure idiom - Could be made even cleaner still, if able to assume GCC or Clang only, with fancy automatic-destruction-upon-leaving-scope magic by putting
__attribute__((cleanup(func)))right after the variable name in thechunkdeclaration; and then having a static functionvoid func(char **p) { free(*p); }
- Could be made a bit tidier with the
- Will need a check-for-
- Dynamically decide whether to use
allocaormallocdepending on whetherblksizeis above or below the "reasonable maximum" size- This is nice because it keeps things fast-and-on-the-stack for the "normal" fast-path case of small
blksize - However this gets slightly hairy, as the way to implement it likely involves:
- having two pointers (e.g.
chunkpluschunk_malloc = NULL) - in small
blksizecase, directly assignchunk = alloca(blksize) - in large
blksizecase, assignchunk = chunk_malloc = malloc(blksize)(withNULLcheck of course) - use
chunkas the actual pointer - as in (2) above, ensure that all code paths do
free(chunk_malloc)one way or another (it'll beNULLif theallocapath was taken, and sofreeis a no-op) - most of the actual hairiness relates to the fact that all the pointers are
restrict-qualified, and now there are two pointers that... kinda alias the same thing; I don't think it's actually a problem, since aliasing only really concerns reads/writes through the pointers; but if something here did happen to violate the rules at all, then the gods of Undefined Behavior (a.k.a. compiler optimizer writers, who take sadistic pleasure in exploiting UB to make your life miserable) will silently unleash their wrath upon your soul in various horrific-but-invisible ways
- having two pointers (e.g.
- This is nice because it keeps things fast-and-on-the-stack for the "normal" fast-path case of small
- If able to assume C11, you could potentially use a static
thread_localbuffer I guess... though this is perhaps a generally idiotic idea
Thanks; and apologies if this was excessively over-explained for what it is.

That's not useful, because the ABIs will ignore your suggestion. All this does is cause warnings in C++17 mode:
warning: ISO C++17 does not allow ‘register’ storage class specifier [-Wregister]
If you really want to pass parameters as registers, add regparm(3) to your GCC attributes. In my opinion, that's not worth it, because the only platform that still passes parameters on the stack is i386.
README erroneously mentions libsha2
I'm not sure whether that's supposed to be libsha3 instead, or just is completely wrong, so sorry for the lack of a PR.
