2020-05-06Use __attribute__((fallthrough)) rather than magic GCC comments.Nick Mathewson
GCC added an implicit-fallthrough warning a while back, where it would complain if you had a nontrivial "case:" block that didn't end with break, return, or something like that. Clang recently added the same thing. GCC, however, would let you annotate a fall-through as intended by any of various magic "/* fall through */" comments. Clang, however, only seems to like "__attribute__((fallthrough))". Fortunately, GCC accepts that too. A previous commit in this branch defined a FALLTHROUGH macro to do the right thing if GNUC is defined; here we replace all of our "fall through" comments with uses of that macro. This is an automated commit, made with the following perl one-liner: #!/usr/bin/perl -i -p s#/\* *falls? ?thr.*?\*/#FALLTHROUGH;#i;

2018-01-11On shutdown, mark openssl as uninitialized.Nick Mathewson
This causes openssl to get completely reinitialized on startup, which is probably a good idea.
2017-05-30Fix GCC 7 -Wimplicit-fallthrough warningsAndreas Stieger
Add magic comments recognized by default -Wimplicit-fallthrough=3 or break, as required.
2017-03-14Improve keccak-tiny performance by 15% on LE intelNick Mathewson
The 64-bit load and store code was generating pretty bad output with my compiler, so I extracted the code from csiphash and used that instead. Close ticket 21737

2015-11-05Fix SipHash-2-4 performance for non multiple of 8 buffers.Yawning Angel
Code cribbed from Andrew Moon's Public Domain SipHash-2-4 implementation (which IMO is also cleaner). Fixes bug 17544.
2015-03-23Merge remote-tracking branch 'public/bug15436_025' into maint-0.2.6Nick Mathewson
2015-03-23Fix unaligned access in SipHash-2-4.Yawning Angel
The compiler is allowed to assume that a "uint64_t *" is aligned correctly, and will inline a version of memcpy that acts as such. Use "uint8_t *", so the compiler does the right thing.
2014-10-28Add another year to our copyright dates.Nick Mathewson
Because in 95 years, we or our successors will surely care about enforcing the BSD license terms on this code. Right?
2014-04-07Make csiphash use the proper endian-converter on solarisNick Mathewson
fixes bug 11426; bugfix on 0.2.5.3-alpha, where csiphash was introduced.
2014-03-18csiphash: don't attempt unaligned accessNick Mathewson
In digestmap_set/get benchmarks, doing unaligned access on x86 doesn't save more than a percent or so in the fast case. In the slow case (where we cross a cache line), it could be pretty expensive. It also makes ubsan unhappy.
2014-02-17Appropriately condition the _le64toh macro definition for OpenBSD.dana koch
This corrects a linker error on OpenBSD, where the function is called letoh64. See also http://git.kernel.org/cgit/docs/man-pages/man-pages.git/tree/man3/endian.3#n84.
2014-02-12Randomize the global siphash key at startupNick Mathewson
This completes our conversion to using siphash for our hash functions.

2014-02-12csiphash: avoid unaligned access on non-x86Nick Mathewson
2014-02-12Get csiphash better integrated with our build systemNick Mathewson
2014-02-12Raw import of Marek Majkowski's cisphash.cNick Mathewson
siphash is a hash function designed for producing hard-to-predict 64-bit outputs from short inputs and a 128-bit key. It's chosen for security and speed. See https://131002.net/siphash/ for more information on siphash. Source: https://github.com/majek/csiphash/
