47b9e78e07 Cast pointers through uintptr_t under JNI 
Fixes warnings of the form "warning: cast to pointer from integer of
different size" when building on 32 bit platforms. This is the same
approach used for pointer conversions in the openjdk sources.

bcc4881d3a Add some missing VERIFY_CHECK(ctx != NULL) for functions that use ARG_CHECK 
The `ARG_CHECK` macro requires that a variable called `ctx` exist and be
non-NULL. However, in several functions that do not use the context variable,
we simply ignore it with `(void)ctx`. Replace these with explicit checks for
non-NULLness to avoid invalid memory accesses.

3f8fdfbec1 build: fix x86_64 asm detection for some compilers 
I Noticed this on OSX with clang, though it likely happens elsewhere as well.
The result is disabled x86_64 asm.

Due to missing escaping, this $0 was interpreted as the function name
SECP_64BIT_ASM_CHECK, causing the compile-check to be broken on some compilers.

The actual check looked like this:

int main()
{
  uint64_t a = 11, tmp;
  __asm__ __volatile__("movq SECP_64BIT_ASM_CHECKx100000000,%1; mulq %%rsi" : "+a"(a) : "S"(tmp) : "cc", "%rdx");
  return 0;
}

It seems even more odd that it compiled anywhere.

5b71a3f Better error case handling for pubkey_create & pubkey_serialize, more tests. (Gregory Maxwell)
 2015-10-31 00:41:21 +01:00

26abce75ea Adds 32 static test vectors for scalar mul, sqr, inv. 
These were generated by testing more than 10^12 random test vectors
 for coverage on instrumented (comparison operator outcomes) 32-bit
 and 64-bit code, plus additional edge condition requirements (e.g.
 inputs of 0, 1, -1) and then solving a minimum set cover problem.

The required responses were generated with Sage.

This significantly improves the lcov branch coverage report and
 makes the tests much more sensitive to mutation testing of the
 scalar code.

The challenges and responses are in the form of pairs of scalars:
  C1 * C2 == R1
  (C1 * C2) * (1 / C2) == C1
  C2 * (1 / C2) == 1
  C1 * C1 == R2
  C1^2    == R2

5b71a3f460 Better error case handling for pubkey_create & pubkey_serialize, more tests. 
Makes secp256k1_ec_pubkey_serialize set the length to zero on failure,
 also makes secp256k1_ec_pubkey_create set the pubkey to zeros when
 the key argument is NULL.

Also adds many additional ARGCHECK tests.
