| | | | | | | | | | | | XLC 16 changed which macros are used to identify it. Older versions of XLC didn't work correctly anyway (#1581 #1509 etc), so just drop support for recognizing those versions.

|
* Add a fuzzer for Memory_PoolJack Lloyd2018-12-292-1/+115
| | | | | | | | | Basically, test that it works. Accepts a sequence of alloc+free operations and verify that each pointer returned does not overlap with any other outstanding allocation, that the memory returned is zeroed, and that alignment is respected. Intended for testing #1800 but no reason not to land this first.

| * Use posix_memalign instead of mmap for creating the locking poolJack Lloyd2018-12-282-27/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | As described in #602, using mmap with fork causes problems because the mmap remains shared in the child instead of being copy-on-write, then the parent and child stomp on each others memory. However we really do not need mmap semantics, we just want a block of memory that is page-aligned, which can be done with posix_memalign instead. This was added in POSIX.1-2001 and seems to be implemented by all modern systems. Closes #602
* | Avoid const-time modulo in DSA verificationJack Lloyd2018-12-291-1/+11
| | | | | | | | | | | | It has a substantial perf hit and is not necessary. It may not be really necessary for signatures either but leave that as it, with a comment explaining.
* | Simplifications in BigIntJack Lloyd2018-12-291-7/+1
|/ | | | | Use ct_is_zero instead of more complicated construction, and avoid duplicated size check/resize - Data::set_word will handle it.

| * Fix Barrett reduction input boundJack Lloyd2018-12-264-17/+28
|/ | | | | | | | | | | | In the long ago when I wrote the Barrett code I must have missed that Barrett works for any input < 2^2k where k is the word size of the modulus. Fixing this has several nice effects, it is faster because it replaces a multiprecision comparison with a single size_t compare, and now the branch does not reveal information about the input or modulus, but only their word lengths, which is not considered sensitive. Fixing this allows reverting the change make in a57ce5a4fd2 and now RSA signing is even slightly faster than in 2.8, rather than 30% slower.
